Fan Fic: Rosario Vampire: Brightest Darkness
Rosario Vampire: Brightest Darkness is a series of Rosario + Vampire Continuation Fics written by Lord Daemon. The fic is split into six parts, Act I, Act II, Act III, Act IV, Act V, and Act VI, with a seventh act on the way.

Note: This page is chock full of spoilers, many of them unmarked, so it is probably for the best if you read it then come back here. You Have Been Warned.

This fic contains examples of the following tropes:


  • 0% Approval Rating:
    • During the majority of Act III, Tsukune and co, suffer this from most of the other students, who believe them to be fakers claiming to fight Fairy Tale for attention. From the climax of Act III onwards, after the other students see the group successfully fend off Kuyou and a Fairy Tale invasion force firsthand, they are the heroes of the academy from there on out.
    • In Act VI chapter 45, all the members of the Fairy Tale faction that Gyokuro leads express open disdain for the late Kiria, to the extent that they view his brutal death at the hands of Ghoul!Tsukune as a Mercy Kill.
  • 100% Adoration Rating: In Act III chapter 42 onwards, the student body as a whole realizes that the rumors that Tsukune and co. were fighting Fairy Tale were true when they see them fight off Kuyou and a Fairy Tale squad firsthand, which makes them the heroes of the academy. The good publicity is increased even further at the end of Act IV after the group slays Alucard.
  • A-Cup Angst/Not Growing Up Sucks: In Act V chapter 19, Arial bemoans the fact that, since she died as a child and will remain in the body of one in Heaven forever, her breasts will never develop.
  • Abnormal Ammo: In Act IV chapter 17, in order to cure the victims of the love-struck potion, Ruby conjures a bazooka with an airburst warhead specifically designed to release the antidote.
  • Abusive Parents:
    • Babylon imprisoned his daughter Pandora in Pandora's Box, whereas Hex openly states that he doesn't consider Babylon a father at all. As Hex puts it in Act VI chapter 40, nothing would make himself and Pandora happier than to see Babylon torn apart before their eyes.
    • In the first chapter of Act IV, Issa promptly starts physically beating Akua and Kahlua in a rage when he discovers that they had been working for Fairy Tale and damaged the Shuzen family's reputation by doing so. When he discovers that Kokoa and Moka had also accidentally turned Tsukune into a ghoul and not killed him immediately, uncaring that Tsukune had been cured of the ghoul by the Chrono Displacement spell, he begins to attack them as well before Tsukune calls him out and convinces him to give Akua and Kahlua a chance to redeem themselves.
  • Acquired Poison Immunity: Not exactly poison immunity, but the basic principle is the same; by the time of Act II chapter 30, Tsukune is so used to the girls' seduction attempts that Moka, Kokoa, and Yukari's attempts to give him a nosebleed via fanservice end in failure.
  • Adaptational Heroism: Unlike in canon, Akua and Kahlua reform at the end of Act III and become trusted friends and allies of Tsukune's group.
  • Adaptational Villainy:
    • In canon, Tsukune's ghoul form was largely depicted as an instinctive, mindless Berserker. Here, it's shown as a full-fledged Superpowered Evil Side with its own identity and personality.
    • Though Hokuto was always an antagonist in the manga, he was more of a Wild Card to the extent that he helped Tsukune and Moka stop his own plan. Here, he's a straight-up no-gray-area villain and a blatant Straw Nihilist who openly expresses the view that life itself is nothing but a meaningless plague that must be wiped out.
  • Adult Fear: In Act VI chapter 47, Mizore, Kurumu, and Yukari's parents all face this, having just witnessed their daughters get arrested and nearly executed by the HDA on national television.
  • Adults Are Useless: Headmaster Mikogami, as usual. Best displayed in Act III chapters 40-44; both Kuyou and a Fairy Tale armada invade and attack Yokai Academy one after the other, and instead of trying to stop them, he decides to sit on his ass and let Tsukune's group take care of it.
  • Aesop Amnesia: During the events of Act I, Kokoa learns not to chase after someone who's already taken when Dark points this out to her in chapter 20. By the time of Act II, she's fallen in love with Tsukune and challenges Moka for the right to be his mate, and ends up learning the same lesson all over again.
  • Affably Evil/Faux Affably Evil:
    • For all of his Blue and Orange Morality, Hex is quite pleasant and polite, and doesn't particularly care if he loses at his game; it's all a part of luck, after all.
    • Jovian and Jacqueline often act polite and sweet, even managing to earn the trust of Kyouko and Tsukune's mom by acting as such. Regardless, they're both unrepentant Psycho Lesbians and sadists who revel in causing others pain, especially by raping those Hokuto has them hold hostage. The new Jovian and Jacqueline under Talon's control in Act VI are considerably more genuine Affably Evil.
    • Hokuto also acts polite and refined, while openly declaring life itself to be evil and meaningless.
    • Evil!Falla can also act and speak polite when it suits her, but all the same, she's a complete Jerkass with a Lack of Empathy that borders on sociopathy.
  • Affectionate Nickname:
    • Dark often calls Mizore his "little snow bunny."
    • Felucia calls Mizore "slushy," initially as an insult, but as she warms up to her, it becomes more affectionate.
    • Kurumu calls Rason "angel boy." Of course, he doesn't like it when anyone but Kurumu calls him that.
  • Aggressive Categorism/Van Helsing Hate Crimes:
    • Most of Rason's fellow angels adamantly refuse to see monsters as anything but savage beasts, while looking to humans as near-pristine examples of goodness. Rason was actually banished from Heaven in the past because he saved a monster from a human. It took Rason's efforts to save Luna and Falla from his fellow angels, as well as direct interference from God Himself, to get the angels to start thinking differently, and by the end of Act IV, they have all finally accepted that monsters can be good too, even allowing them into Heaven.
    • The Human Defense Agency, or HDA, that came into being after Alucard's attack and the subsequent exposure of monsters, is also fairly quick to write off all monsters as evil simply because of the actions of a few people, with one soldier flat-out telling Moka and Akasha to their faces that, as far as he's concerned, monsters like them aren't even animals. However, Moka and Akasha's efforts in Act VI with their director, who is actually not so black-and-white, seem to be making some progress.
  • Ain't Too Proud to Beg:
    • In Act I chapter 20, Kokoa begs Dark not to reject her; Inner Moka is quick to call her out on it, remarking that after all her talk about vampire pride, Kokoa is still stooping as low as to beg a boy who is already taken for his love.
    • In Act VI chapter 35, when Talon remarks that he'll simply give Jovian and Jacqueline the order to be free because he doesn't want them to be his slaves, the two let out a Big "NO!" before getting down on their knees and begging him not to do so.
  • The Alcoholic: In the flashback in Act IV chapter 29, Felucia asks Kenzo what's stopping her from just wiping out humanity herself, Kenzo points out that part of it is because she tends to stop and get plastered at the first bar she sees.
  • All Animals Are Dogs: In Act VI chapter 22, after Fang Fang's phoenix nearly incinerates Complica and Arial, Fang Fang actually scolds it as if it were a puppy.
  • All for Nothing:
    • Throughout Act III, Akua and Kahlua willingly work for Kiria and aid him in his plan to rewrite history with the Chrono Displacement spell, going to such lengths as stealing said spell from their father's secret archive, turning themselves into hybrids with Alucard's blood, and killing numerous innocents, because they hoped to make Issa one of the top rulers of the new world that Kiria intended to create. They're naturally horrified when they discover that they were nothing but Kiria's Unwitting Pawns and that part of his Evil Plan would have involved having the two infected with Blackheart and sent back in time to destroy Issa's empire from within so he would be the strongest monster of them all, which is anything but what they wanted; they spend the entirety of Act IV trying to atone for their actions. To further drive the nail in, Kiria's plan was doomed to fail from the start, as if Tsukune and the others had fallen, Luna would have killed Kiria herself and then let the Chrono Displacement spell go critical and destroy everything in a fit of madness.
    • During the final chapters of Act V, the actions of Babylon's minions lead the HDA to declare war on monsters, leading them to arrest and quarantine any monster they can find and drive the dark lords out of the human world. After some events, however, they realize by Act VI chapter 52 that their efforts were in vain; Babylon had been targeting the monster world all along, and the humans were unfortunate enough to get caught in the crossfire.
  • All Myths Are True: Discussed and largely defied in Act VI chapter 43. Kyouko mentions several different kinds of monster myths, such as silver bullets killing werewolves, sirens luring men to their deaths, and witches flying on broomsticks and eating children, and the gang all dismiss them as ridiculous, even stating that wooden stakes through the heart and getting shot with silver bullets would kill anyone. Kurumu, however, mentions that succubi can drain the life force out of the men they have sex with, but as she puts it, said succubus would have to "be a bitch" to do so.
  • All of the Other Reindeer: Throughout much of Act III, most of the other students ostracize and harass Tsukune and his friends, believing them to be Fake Ultimate Heroes claiming to fight Fairy Tale. However, the disrespect and criticism all comes to an end when the students see the gang fight off Kuyou and a Fairy Tale squadron firsthand.
  • All Witches Have Cats: Discussed and defied along with many other monster myths in Act VI chapter 43. When Kyouko mentions the myth that witches keep black cats as pets, Ruby states that she's allergic to cats (though not Cat Girls like Ms. Nekonome).
  • Aloof Big Sister: The original Falla took this trope Up to Eleven, noted as always being cold to Complica and not treating her like a sister at all. On top of it all, she informed Complica of how to cast the Chrono Displacement spell so as to go back in time and spend one more day with her crush while deliberately neglecting to inform her that the spell would kill her the next day (though it's revealed in Act VI that Complica knew it would happen all along) and then explicitly telling Luna to her face that she was glad Complica was dead.
  • Alternate Identity Amnesia: In Acts II and III, Tsukune typically blacks out and has no idea of what happened when the ghoul is in control.
  • Always Identical Twins: Apoch and Astreal Ezrana are identical except for their hair and eye colors: Apoch has short black hair and Supernatural Gold Eyes, whereas Astreal has long blond hair and black eyes.
  • Always in Class One: So far, all of the school-aged OCs (Rason, Dark, Felucia, Ahakon, Luna, etc.) have ended up in Ms. Nekonome's class with Tsukune and his friends. Rason even lampshades it.
  • Always Save the Girl: Mizore is Dark's top priority no matter what. If he so much as suspects that her life is in danger, he'll do anything short of killing his closest friends to protect her.
  • Ambiguous Disorder: Complica has always had a problem with her train of thought, has a short attention span, and her mind constantly runs at full speed. In Act VI chapter 19, she seemingly hallucinates four copies of herself while taking a bath.
  • Ambition Is Evil: The original Falla's desire to become queen led to her killing her own father and then destroying her homeland and entire species in a fit of rage, deciding if she couldn't be queen of their kingdom, then they would all fade into time.
  • Amnesiac Dissonance: In Act IV, Falla's Alternate Self cannot remember anything of her past except her name due to a head injury. When she regains her memories in chapter 22 thanks to Lilith's Mirror, she's horrified to discover just what an evil monster she was.
  • An Arm and a Leg:
    • As shown in his flashback in Act I chapter 18, the very first thing Dark did when he turned on his old master was chop off his hand.
    • In Act II chapter 25, Dark tears off all of Miyabi's limbs one by one, though not before he crushes all of the bones in said limbs to powder.
    • In Act III chapter 52, Ghoul!Tsukune tears off Kiria's arms as well.
    • In Act IV chapter 29, Apoch chops off one of Jovian's hands before finishing her off.
    • In Act V chapter 35, Evil!Falla gleefully tears her Good Counterpart's leg, arm, and wings off. Good!Falla's body is subsequently repaired by Ceal.
    • In Act VI chapter 35, Kahlua gets her arm chopped off by Jacqueline. After Ten-Ten rescues them, she reattaches the arm using special slug-like creatures.
    • In Act VI chapter 40, Hex demonstrates his power by severing Issa's hand with a spatial blade and then reattaching it.
    • Ceal's left hand was severed and destroyed as a result of Pandora's Jackass Genie tendencies; he replaced it with one created from the body mass of a necro demon.
  • An Offer You Can't Refuse: In Act IV chapter 23, Hokuto forces Tsukune and co. to hand Moka over to him by revealing that he has had Jovian and Jacqueline take Kyouko and Tsukune's mother hostage.
  • Anatomically Impossible Sex:
    • In Act VI chapter 26, when Luna discovers that Pandora enjoys making love with the various monsters trapped in the box with her, she's completely shocked, considering the fact that Pandora has the appearance of a little girl and the monsters in question are much bigger than she is.
    • In Act VI chapter 41, Sun, Kurumu, and Ran end up seeing Kokoa having sex with Gin in his werewolf form, and are astonished at the seeming physical impossibility of the task.
    Kurumu: You think she's using any lubricant?
    Ran: What?! That's the stupidest thing you could say right now! Of course she would have to be using lubricant. For God's sake, if she didn't, he would have ruined her from the very start!
  • And I Must Scream:
    • When Ghaldin tracks them down and seizes control back over them, Apoch and Astreal are involuntarily forced to fight Tsukune and the others, fully conscious of their actions and unable to control themselves all the while. Dark, having also been controlled, is aware of his actions as well, and as soon as he's freed when Inner Moka kills Ghaldin, he promptly takes to Pummeling the Corpse in a rage.
    • After being defeated by Luna, Falla was stranded in the time stream, with nothing better to do than shift all over time and the monster world.
    • In Act III chapter 12, it's stated that Kokoa's ghoul infection led her to force herself on Tsukune; all the while, Kokoa can do nothing but watch helplessly and try in vain to stop.
    • In Act V chapter 10, it's revealed that all of those controlled by the Otonashi sisters are conscious and aware while being controlled. It also works in a positive way, as Tsukune and the guys, while under their control, are able to hear the siren sisters praying to the Almighty for their freedom from their master Babylon, and for forgiveness for being forced to do his bidding, which is what motivates them to help free the trio from Babylon's control.
    • In Act V chapter 35, it's stated that the brainwashed Apoch and Astreal are fully conscious of their actions and can do nothing but watch as they're forced to fight their friends against their will.
  • And Show It to You:
    • In Act II, Dark finishes off Miyabi by ripping his spine out of his body.
    • In the final chapter of Act III, Ghoul!Tsukune rips several of Kiria's organs out with his bare hands.
  • And Then What?: When Moka kills their master, thus freeing them, Apoch and Astreal admit that they never really thought about what they would do with their lives after getting their freedom. Ruby solves the problem by making them her assistants.
  • And Your Little Dog Too:
    • In Act IV chapter 11, after revealing that her attempts at redemption were all an act, Falla tells Tsukune that when she's finished killing them, she'll visit Tsukune's mom and cousin and show them just "what kind of friend" she really is. Fortunately, she doesn't live long enough to make good on her threat.
    • As revealed in Act VI chapter 53, this is Gyokuro's plan for the Blackheart-enhanced clones of Moka, Ruby, Kokoa, Kurumu, Mizore, and Yukari: to have them destroy everyone and everything the originals hold dear before killing the girls themselves.
  • Angelic Beauty: In Act III, Ahakon describes Apoch and Astreal as such.
  • Anger Born of Worry: In Act II chapter 25, after saving Mizore from her suicide attempt, Kurumu angrily slaps her before tearfully demanding to know why she tried to kill herself.
  • Anti-Hero:
    • Dark Kuyumaya is a Type II or III. He's undoubtedly on the side of good and protective of his friends, but kills and injures with little-to-no hesitation. However, as he explains in Act VI chapter 45, he doesn't kill without reason.
    • Ceal Erres, which is best displayed in Act VI chapter 1. While the others had agreed not to kill any HDA operatives while breaking Moka and the others out, Ceal dismisses that and promptly starts killing any operatives who oppose them, flat-out stating that if someone gets in his way, they die.
  • Anti-Human Alliance: Fairy Tale, though it doesn't stop them from recruiting humans.
  • Anti-Villain:
    • Akua and Kahlua during Act III. They're working for Fairy Tale because they intend to put their father on top of the new world order Kiria plans to create. After they discover that Kiria in fact planned to infect them with Blackheart and then send them back to kill their father, they have a Heel Realization, and are allies of the group from Act IV onwards.
    • Talon Ryashen is a Type I or II. He's hunting down everyone who was ever associated with Fairy Tale in any way, regardless of whether or not they defected or were even aware of the organization's true agenda. However, as he puts it, they turned him into a monster and took everything from him, and thus, he pretty much has nothing left to live for but revenge.
    • Jovian and Jacqueline Kikion. As they explain in Act VI, they're not naturally good or evil on their own; rather, their morality is shaped to match their master's at the time. The original Kikions served Hokuto, who was a Straw Nihilist seeking to bring about The End of the World as We Know It, so they themselves became sadistic Psycho Lesbians who take their time to rape Felucia and Kyouko while holding them hostage. The new Jovian and Jacqueline who were summoned by Talon, who, while misguided and driven by vengeance against Fairy Tale, is not actually evil, and are thus far more affable and sympathetic, even comforting Rin.
  • Anything You Can Do, I Can Do Better: Leon says this exact phrase word-for-word twice while fighting Jovian and Jacqueline, first when he initially copies their powers, and then as a Pre-Mortem One-Liner when he uses a Wave Motion Gun to vaporize Jacqueline from the waist up.
  • Arbitrary Skepticism:
    • Despite living in a world filled with all manner of monsters and demons, Ahakon is genuinely shocked to see Kou, a talking bat. Kurumu even lampshades it.
    • In Acts V and VI, the HDA, despite knowing of and accepting the existence of monsters and magic, find the idea of Time Travel ridiculous, at least until the final chapters of Act VI.
  • Arc Villain:
    • Act I: Ghaldin Rayazo, then Dahlzin Aragaso
    • Act II: Fairy Tale and Tsukune's ghoul form
    • Act III: Kiria Yoshi
    • Act IV: Hokuto Kaneshiro and Alucard
    • Acts V and VI: Babylon
  • Arc Words: "A life is a life, no matter what it is."
  • Armies Are Evil: Babylon's army is as evil as they come, though quite a few of them are Brainwashed and Crazy.
  • Armor-Piercing Slap:
    • In Act II chapter 25, after thwarting Mizore's attempted suicide, Kurumu slaps her twice while demanding to know what she was thinking.
    • In Act III chapter 1, Kokoa also slaps Tsukune when he continues to insist that his transformation into a ghoul wasn't entirely her fault because she was tricked.
    • In Act VI chapter 21, Sivia slaps Rathieal while chewing him out for sending so many monsters after Luna without Babylon's authorization. Subverted; instead of just standing there and taking it, Rathieal kills her on the spot because he Hates Being Touched.
  • Arson, Murder, and Jaywalking:
    • In Act IV chapter 34, Issa has this to say after the Day of Alucard:
    Issa: I trusted my daughters to you, boy, and what do I get in return? Alucard is revived and nearly destroys the world because you couldn't keep Moka safe. The humans now know of monsters everywhere because you couldn't keep things quiet. And my youngest daughter is running around half-naked.
    • In Act VI chapter 47, Ageha remarks on the parents' situation:
    Ageha: My daughter could have been killed, I may never see her again, and on top of all that, I'm stuck riding in a low-class school bus in the human world with a driver who smells like an ashtray!
    • Moka has a similar reaction in Act VI chapter 50 after being brought up to speed on everything that had happened while she was negotiating with the HDA, leading to this exchange:
    Moka: Yokai Academy is destroyed? A reality bender saved Luna? Arial's not insane about Dark anymore?
    Arial: Hey, I'm not crazy. And why am I being compared to those other things?
  • Artificial Human/Pure Magic Being: Apoch and Astreal, as well as Jovian and Jacqueline, are summoned beings created by magic.
  • Artists: The Cii sisters are all noted on multiple occasions to be extremely talented at drawing.
  • Ascend to a Higher Plane of Existence: In Act VI chapter 52, Complica is seemingly erased from existence due to the cost of Chrono Displacement. However, Hex reveals that instead of having her soul destroyed, Complica actually became an anomaly in existence similar to him; though even Hex is unsure what exactly became of Complica or where she ended up, he does know that Complica is still alive in some form.
  • Ascended Fangirl: Ran began to idolize Ahakon after witnessing him aid in Alucard's defeat, and is a friend of his from Act V onwards.
  • Asshole Victim/Kick the Son of a Bitch:
    • The wizard who originally summoned Dark and forced him to kill Arial. When a guy has no qualms against doing something that even the most vile demons of Hell find despicable, you know he had it coming when Dark turns on him and brutally murders him in a rage.
    • In Act I chapter 14, no one regrets the death of Ghaldin, particularly since he forced the Ezrana twins, as well as Rason and Dark, to try to kill Tsukune's posse while explicitly stating that Apoch and Astreal are nothing but his slaves for him to use as he wishes.
    • Later, in Act I chapter 16, when Dark overhears that Kotsubo tried to molest Mizore the previous year, he loses his temper and nearly kills him, and is only stopped by Tsukune and Rason's insistence that Kotsubo isn't worth it.
    • In Act II, when they discover that Miyabi raped Mizore, Dark is so furious that he attacks Miyabi and kills him in the slowest and most brutal manner possible; despite being horrified at Dark's brutality, Tsukune and the others nonetheless have No Sympathy for Miyabi and unanimously agree that he deserved every second of it.
    • In Act III, Kano repeatedly blackmails the girls of the group into letting him take dirty pictures of them, and then ultimately decides to try to rape them. Cue Karmic Death in chapter 31 when Luna uses her magic to stop time and then bites off the back of his head just as he's about to force himself on Mizore.
    • In Act IV chapter 28, Jovian and Jacqueline are killed by Apoch and Astreal. Considering that they had previously raped Felucia and Kyouko and reduced a good portion of Tsukune's hometown to rubble, they definitely had it coming, with Ahakon and Yukari in particular openly rejoicing their deaths.
    • After everything Hokuto has done, including kidnapping and brainwashing Felucia, setting Kuyou loose on Yokai Academy, letting Jovian and Jacqueline rape and torture Felucia to the point of Sanity Slippage, holding Tsukune's family hostage, and being indirectly responsible for the deaths of Felucia, Kenzo's gang, and the original Ezrana sisters, the entire gang cheers Tsukune on as he beats the ever-loving shit out of Hokuto and kills him in Act IV chapter 31.
    • Early on in Act VI, Ceal kills Jenner, head of the HDA. It's pretty hard to feel sorry for Jenner when one considers that he was an openly anti-monster General Ripper who has spent most of his screen-time lambasting monsters to the extent that he outright states he'll take any possible excuse he can to declare open war on them.
    • In Act VI chapter 17, Kurumu sides with Mizore after Mizore beats Arial to a bloody pulp, stating that, even if Arial is a disembodied soul and any fatal damage will destroy her soul and erase her from existence, Arial nonetheless deserved it considering the fact that she nearly killed Mizore in a fit of jealousy and stole her wedding ring.
  • The Atoner:
    • Dark's entire motivation is to atone for the lives he was forced to take while working for first his former master, and then Fairy Tale.
    • In Act III, because she was responsible for the ghoul managing to get enough power to hijack Tsukune's body completely, Kokoa swears fealty to Tsukune in atonement.
    • After regaining her memories, Falla seeks to atone for her own crimes.
    • In Act IV, Akua and Kahlua also seek to make up for what they did while working for Fairy Tale.
  • Attempted Rape:
    • In the past, Rason saved Luna from being raped by a male human.
    • In Act III chapter 31, after forcing the girls into several pornographic picture sessions, Kano decides to have his way with them, starting with Mizore. However, Luna uses her magic to break herself and the others free, and then eats the entire back half of Kano's head.
  • Attention Deficit... Ooh, Shiny!: In the flashback in Act IV chapter 29, Kenzo mentions that Felucia has a short attention span; Felucia proves him right by drifting off and absently looking out the window while he's talking to her.
  • Attention Whore: Mizore's first impression of Felucia Sonsta is that she's "a tramp who just barges in and demands all the attention from everybody around her."
  • Awful Truth: Throughout the first handful of chapters in Act VI, Mizore and the others try to keep Dark from discovering that Arial, whom he had long honored and looked up to as his guardian angel, is really a stubborn, hot-tempered Yandere who is obsessed with him to the point that she very nearly killed Mizore in a jealous rage and stole Mizore's wedding ring right off of her finger. They ultimately have no choice but to tell Dark the truth after Mizore and Arial have a Designated Girl Fight that ends with Mizore beating Arial to an inch of her life right in front of him, and Dark has a major Heroic BSOD. The chapter in which he finds out is fittingly titled "Painful Truth."
  • Ax-Crazy:
    • Tsukune's ghoul form counts to a T. In Act III chapter 52, when unleashed, he proceeds to brutally dismember and disembowel Kiria with his bare hands, laughing while he does it.
    • Jovian and Jacqueline also qualify, particularly the originals who served Hokuto. In Act III chapter 52, when Hokuto warns Felucia that Jovian will kill Ruby and Tsukune if Felucia won't hold them back, Jovian gleefully cheers that she loves killing. The resummoned Jovian and Jacqueline in Act VI are considerably more mellow.
    • Arial often comes across as this in Act VI, in part due to her obsession with Dark; in chapter 7, the very first thing she does as soon as she discovers that Mizore is Dark's girlfriend is use her ice claws to literally tear Mizore apart in a jealous rage right in front of everybody; it's outright acknowledged that, had Ceal not reconstructed her body, Mizore would have died from Arial's attack.
    • As revealed in Act VI chapter 52, the Fairy Tale-created clone of Moka is little more than a savage animal.
  • Awesome but Impractical:
    • Kokoa's overcharge grants her enough power to go toe-to-toe with Inner Moka, but even the slightest attack completely depletes her energy, and if she doesn't use it up, it can lead to a Superpower Meltdown.
    • The Artimus Arrow spell, as seen in Act VI, is powerful enough to one-shot a Nigh Invulnerable rylo demon, but draws so much power from the magical ether that, according to Yukari and Ruby, if they even tried to hold it, the power behind it would cause their bodies to literally explode.
  • Back from the Dead/Death Is Cheap: Several examples:
    • In Act II, Kurumu is killed by duplicates of Apoch and Astreal under Fairy Tale's control, but Rason manages to convince the Almighty and the Lord of Hell to bring her back to life.
    • Both Dark and the Ezrana sisters have been killed, but return to life typically by being resummoned.
    • In the climax of Act III, everyone in the group except for Tsukune himself dies during the assault on Kiria's stronghold, but Tsukune uses the Chrono Displacement spell to reverse time by a day and prevent their deaths.
    • In Act V, after being rejected by a mind-controlled Rason, Kurumu literally dies of a broken heart, but a quick Get A Hold Of Yourself Man from the Lord of Hell down below snaps her out of her funk and convinces her to go back.
    • In Act VI, Akasha is resurrected by the Almighty as part of a Redemption Quest, though she herself is unaware that she has been truly brought back until Hex informs her as such in chapter 51.
  • Bad Boss: In his short appearance in Act I, Ghaldin physically abuses the Ezrana sisters and declares them to be nothing more than his slaves and weapons for him to use as he pleases. Small wonder why they ran away from him.
  • The Bad Guy Wins: During the climax of Act IV, Hokuto, as part of his plan, deliberately breaks The Masquerade to the entire human world in order to prove to Moka that humans and monsters could never possibly co-exist. It takes some time, but soon the entire human world becomes afraid of monsters. Ultimately subverted by the end of Act VI.
  • Badass: Several examples, but most notably Dark; in Act I chapter 20, he has a sparring match with Inner Moka in order to prove a point to Kokoa, and it's more-or-less outright stated that Inner Moka only beat him because Dark was trying to lose.
  • Badass Boast:
    • In Act II chapter 25, after brutally tearing Miyabi to pieces, Dark gives out one as he rips out his spinal cord to finish him off:
    Dark: Know this, Miyabi. I will hunt down every last Fairy Tale member for this act. I will murder them all. I will show you all what happens when you mess with a shadow demon!
    • In Act IV chapter 31, Tsukune gives out one of his own to Hokuto right before kicking his ass:
    Tsukune: Hokuto... I'm going to tear you apart for what you've done. I'll fucking send you to Hell for all the pain you've caused. You will never be forgiven for this. Now... KNOW YOUR PLACE!!
  • Badass Cape: Ahakon and Razico wear a red and black one, respectively.
  • Bait and Switch: In Act III chapter 11, when the rest of the group are outside of Tsukune's room reacting in shock, Moka initially assumes that they're referring to Tsukune's cracked Holy Lock and responds in kind... until she walks into the room and sees they were actually shocked at the sight of Kokoa pinning Tsukune down and raping him.
  • Bait-and-Switch Gunshot: In Act III chapter 51, after Ruby returns from destroying the Chrono Displacement spell, we hear a gunshot and it's initially assumed that she was shot by a Fairy Tale operative like in the original timeline. As it turns out, Dark saw the operative coming and shot him before he could shoot Ruby.
  • Bare-Handed Blade Block:
    • In Act III chapter 52, Ghoul!Tsukune pulls one off on Kiria's Sinister Scythe arm before ripping said arm clean off.
    • In Act IV chapter 31, Tsukune blocks two of Hokuto's scythes as such before jerking him forward and kneeing him in the face.
  • Bare Your Midriff: Astreal takes to wearing a belly-bearing tank top from the end of Act IV onwards.
  • Baseball Episode: In Act VI chapter 52, with the knowledge that Complica will shortly perish as a result of the Chrono Displacement spell, the entire group rigs up a big baseball game and stadium for her to have fun in her last moments, knowing that Complica is a baseball fan.
  • Batman Gambit:
    • In Act III, Hokuto's plan to use Kuyou as a distraction while he steals the Artifact of Doom he needs for his plans from Yokai Academy's archives hinged solely on Kuyou's desire for revenge on Tsukune. It works like a charm.
    • In Act III chapter 13, with the revelation that Tsukune's Holy Lock is cracking, Dark claims that he's only keeping Tsukune alive so that Kokoa can atone for her actions and regain her vampire pride, after which he'll kill him to prevent the ghoul from surfacing. However, as Mizore and Felucia explain, if Dark hadn't mentioned Kokoa's debt to Tsukune and act like it was still safe, the headmaster would have had Tsukune killed, knowing that Dark would be the first to kill Tsukune if the ghoul posed any threat; in doing so, Dark has bought the group time to find a way to repair the lock.
  • Batter Up: In Act V chapter 37, Kyouko deals the finishing blow to the evil Falla by beating her to a pulp with a baseball bat.
  • Be Careful What You Wish For:
    • In Act III, after being forced to kiss Jovian in exchange for her repairing Tsukune's Holy Lock, Astreal remarks that she'd rather die than do that again. Kuyou makes his entrance at that very moment and, having overheard Astreal say that, burns her alive for the hell of it.
    • Throughout Act III, Kiria had hoped to unleash Tsukune's ghoul form for his plans. In the final chapter of Act III, Tsukune, about to die anyway as a result of the cost of using Chrono Displacement, deliberately removes the Holy Lock and unleashes the ghoul, which promptly tears Kiria apart.
    Rason: He gave Kiria what he wanted after all... he made sure the bastard wouldn't survive.
    • Several times during the climax of Act IV, Jovian and Jacqueline both remark that they want someone to "go splat." Astreal fulfills this desire by subjecting Jacqueline herself to a Disney Villain Death.
  • Beam-O-War:
    • In Act III chapter 24, during their Designated Girl Fight over Ahakon, Yukari ends up in one with the Ezrana sisters, who begin to overpower her. Ahakon ultimately throws her out of the way and seemingly dies Taking the Bullet; fortunately, Luna jumps in just in time and saves him.
    • In Act IV chapter 28, Astreal ends up in one with Jovian. The clash ends when Apoch steps in and chops Jovian's hand off with her Laser Blade.
  • Because I Said So: In Act IV chapter 16, the angels automatically go along with the Almighty's decision that Rason was right all along and monsters can indeed be good and evil just like humans because the Almighty's word is absolute (though one angel briefly protests it before Gabriel shuts him up).
  • Benevolent Boss:
    • For all of his flaws and insanity in Acts III and IV, Hokuto does treat Jovian and Jacqueline decently and with respect.
    • In Act VI, Talon has this kind of relationship with Rin and the resummoned Kikion sisters. In chapter 53, he even states that he sees them as equals, not underlings.
  • Berserk Button:
    • Hurting or otherwise mistreating women in front of Dark in any way is essentially suicide.
    • Mentioning Arial's Hair-Trigger Temper in front of her is a surefire way to get her to lose said temper.
    • Jovian and Jacqueline do not like the idea of being duplicated or copied in any way. They personally slaughtered any other duplicates of themselves that Fairy Tale tried to create, and in Act V, they're livid when Leon copies their powers.
    • As shown in Act VI chapter 47, despite her preferred lifestyle, Ageha is utterly indignant when Tsurara remarks that she looks like "a whore off the street."
  • Beware the Nice Ones: Tsukune is every bit an All-Loving Hero willing to Turn the Other Cheek in regards to those who wrong him, but piss him off enough and he will break you. Several of the various baddies (Kuyou, Hokuto, etc.) have discovered this the hard way.
  • Beware the Quiet Ones: Dark is well known among the Yokai student body as The Stoic, but it doesn't stop him from putting several bullies in the infirmary and going One-Man Army on a Fairy Tale squadron.
  • Beyond the Impossible: In Acts V and VI, Babylon's powers enable the souls of the dead to leave the afterlife, which the angels of Heaven insist shouldn't be possible.
    Gabriel: Whoever this monster is, he... defied the laws of life itself.
  • Big Brother Instinct:
    • Astreal is extremely protective of Apoch.
    • Hex's entire motive is to free his little sister Pandora from containment.
  • Big Damn Heroes/Just in Time:

    • In Act III chapter 50, Luna shows up just in time to stop Kiria from infecting Tsukune with Blackheart.
    • In Act VI chapter 35, Ten-Ten Huang shows up in the nick of time to save Akua and Kahlua from Talon's wrath and get them to safety.
  • Big "NO!": In Act VI chapter 35, Jovian and Jacqueline let out one when Talon remarks that he'll just order them to be free.
  • Big "Shut Up!":
    • In Act III chapter 52, when Kiria is beginning to remark that he was wondering if Tsukune was going to make it, Tsukune promptly cuts him off:
    Tsukune: Shut the fuck up, Kiria!!
    • In Act VI chapter 44, after Arial hits Mizore in the forehead with an ice kunai, Kurumu starts to taunt her over how it feels, only to be cut off when Mizore screams, "Shut up, Kurumu!"
  • Bigger Is Better in Bed/Gag Penis: In Act VI chapter 41, Gin's penis in werewolf form is said to be so big that both Kurumu and Ran are shocked at how Kokoa can handle it without lubricant.
  • Bizarre Alien Biology: Xarai, Ceal's pet necro demon, is mentioned as having several stomachs.
  • Black and White Morality: Invoked in Act VI chapter 52. With the newly-formed Monster Coalition branch of the HDA, Moka outright tells everyone on national television that there are only two sides of the current conflict: those who stand for peace between humans and monsters, and those who don't, and they will not let anyone ruin the chance for peace.
  • Black Eyes of Evil: Neither are exactly evil, but both Dark and Astreal have black eyes.
  • Black Sheep: The original Falla was this to her family.
  • Blackmail: In Act III chapters 30 and 31, Kano kidnaps all of the girls of the group, takes dirty pictures of them, and threatens to expose the photos to the whole school unless they continue to have such sessions with him and not tell anyone, eventually leading him to force Kokoa into a make-out session. The blackmail comes to an end after Luna kills him just as he's about to rape Mizore, and after Gin of all people finds the photos and has them disposed of.
  • Blade Below the Shoulder:
    • Kahlua can morph one arm into a blade as a result of her infusion with Alucard's blood. As shown in Act IV chapter 27, her blade is durable enough to block one of Jovian's Hand Blasts, though not without causing her pain.
    • Talon has one retractable blade in each arm thanks to Alucard's blood.
  • Blondes Are Evil: Jacqueline, Astreal's Evil Counterpart, is blonde and Ax-Crazy. Averted in the case of Rason and Astreal.
  • Blood from Every Orifice:
    • In Act IV, an alternate Luna suffers this as her chrono dementia reaches deadly levels, bleeding from the mouth, nose, eyes, and ears.
    • In Act IV chapter 20, Kokoa also suffers this as she tests just how far she can push her overcharge before undergoing a Superpower Meltdown.
  • Blood from the Mouth:
    • In Act III chapter 12, Moka coughs up blood after taking a brutal kick to the gut from the ghoul-infected Kokoa; it's even outright stated that said kick nearly killed her on impact.
    • In Act V chapter 11, Tsukune succumbs to his vampiric impulses and drinks Moka's blood, only to puke it back up when his body rejects it.
    • In Act VI chapter 2, an HDA soldier starts bleeding from the mouth as Ceal has Xarai crush him to death.
  • Blood Magic/The Power of Blood:
    • In Act II, Yukari accidentally cuts herself with one of her tarot cards, which was covered with a warlock's blood; said warlock's blood mixes with her own through the cut and gives her a power boost. Kokoa also gets a boost from the warlock after drinking his blood.
    • In Act III, Ahakon comes across Dark's summoning spell, written on the walls of a cave in blood.
    • Several of Fairy Tale's mooks and Super Soldiers, such as Akua, Kahlua, and the Kikion sisters, have been greatly enhanced by Alucard's blood.
    • Moka's blood is the key to breaking Alucard's seal.
    • After Hokuto beats Tsukune to near-death in Act IV, all four Shuzen sisters give him their blood to revive him, turning him into a full-fledged vampire that proceeds to wipe the floor with Hokuto.
  • Blue and Orange Morality:
    • Unlike their pure evil father Babylon, Hex and Pandora don't adhere to any real morality by human and monster standards. While they don't support their dad's plans of conquest, they don't particularly care if the Earth falls to him either, as "lesser beings" are beneath their concern.
    • Jovian and Jacqueline also count to a degree. As they explain when they're resummoned in Act VI, their morality is shaped by their master(s), and they're not naturally good or evil on their own.
  • Body Horror: Ceal has done a variety of body modifications on himself, replacing his lost left hand with a scaly black one and assimilating the organic matter of Pandora's pets into his own body.
  • Bondage Is Bad: As shown in Act III chapter 31, bondage is definitely bad when you're being blackmailed into it by a perverted Camera Fiend like Kano.
    Kano: So I got a thing for bondage. What guy doesn't?
  • Borrowed Catch Phrase: Both Tsukune and Mizore have used Inner Moka's "Know your place!" on different occasions.
  • Bound and Gagged:
    • In Act III chapter 52, after defeating Akua and Kahlua, Tsukune and co. detain them by tying them up back-to-back with chains.
    • Happens to Kyouko in Act V chapter 35, courtesy of Jovian, Jacqueline, and Evil!Falla.
  • Brainwashed and Crazy:
    • In Act I, Apoch and Astreal brainwash Dark and Rason with the intent to use them to fight off their evil master; the "crazy" part comes into play when Ghaldin catches up to them and uses it to his advantage by forcing the boys to do his bidding as well.
    • During Act IV, Felucia is charmed by Jovian and Jacqueline to help Hokuto in his plan.
    • In Act V, Apoch and Astreal are charmed by the revived Jovian and Jacqueline to help them get the keys to Pandora's Box. Unlike Felucia, they're fully conscious and aware while being controlled.
    • Most of the monsters in Babylon's army were charmed by the Otonashi sisters.
  • Break the Cutie: Luna, in part due to her escalating chrono dementia. In Act VI chapter 37, while using his magic to cure said dementia, Ceal remarks that Luna's mind is so damaged that it's a miracle she can still walk and talk.
  • Broke Your Arm Punching Out Cthulhu: In Act III chapter 47, Dark manages to destroy Kiria's Blackheart supply, but gets infected by it himself in the process, causing him to kill Mizore and Gin to pull off a Heroic Sacrifice to stop him. He gets better.
  • Broken Angel: In Act VI, Gabriel loses his angelic powers after losing Hex's game; as a result, his wings lose their feathers and shrivel up. However, shortly afterwards, Ceal uses his magic to restore Gabriel's wings, though he cannot restore his grace. In chapter 46, he becomes a full angel again after kissing Luna.
  • Broken Pedestal/Rebuilt Pedestal:
    • Moka and Kokoa both respected Akua and Kahlua until they discover that the two had been working for Fairy Tale. When the two have switched sides and are being punished by their father in the opening of Act IV, Moka and Kokoa have No Sympathy, with Moka remarking in disgust, "To think we used to respect you both." However, they rebuild that pedestal as the series progresses.
    • During Act III, Tsukune and co. trust and respect Hokuto until chapters 41 and 42, where he reveals that he personally orchestrated Kuyou's attack on Yokai Academy to serve as a distraction while he stole an Artifact of Doom from the secured levels. Ruby in particular is completely disgusted with herself for ever having trusted him.
    • Dark always lived his life in honor of Arial, who granted him his freedom before she died, while Mizore often gave thanks to Arial at night as well. Come Act VI, when Arial comes Back from the Dead, they discover that she had become infatuated with Dark, nearly killing Mizore in a jealous rage. Dark himself suffers a major Heroic BSOD which, several chapters later, results in a massive Freak Out, believing that everything he had fought for in Arial's name was meaningless. Mizore sums it up quite nicely in Act VI chapter 17:
    Mizore: Damn it, I've had enough of this girl. She's not the angel my Dark spoke of. She's not the angel I gave my thanks to at night. She's a fucking nightmare!!
    • Come Act VI chapter 27, however, Arial realizes and accepts that she is Dark's guardian angel/mother figure and nothing more, and they reconcile. In the case of herself and Mizore, however, things are still quite frosty, no pun intended.
  • The Bully: As lampshaded by Rason, Yokai Academy has quite a few bullies.
  • Bullying a Dragon:
    • In Act III, Kano repeatedly blackmails the girls into letting him take dirty pictures of them, laughing off all of their threats and the fact that their boyfriends will be pissed if/when they find out. He knows they're a threat, but with his blackmail and the group's current shaky situation in the school, he's convinced they can't touch him... until Luna bites off the back of his skull at the end of Act III chapter 31.
    • Throughout most of Act III, most of the other students openly taunt and harass the gang, believing that the stories about the group fighting Fairy Tale are nothing but a ploy for attention. Even if that was true, the students have apparently forgotten that these are the same monsters who defeated Kuyou and the Security Committee and put an end to their tyranny over the school, as well as the fact that Dark alone has hospitalized several bullies that made the near-fatal mistake of messing with him.
    • In Acts IV and V, several of the other male students try to hit on Moka and the other girls despite full knowledge of who they're dating. It's even lampshaded how stupid this is.
    • In Act VI chapter 45, Kurumu briefly teases Kokoa over having sex with Gin, forgetting for the moment that Sun did the same earlier and is laying in the infirmary brain-dead as a result; when Ran reminds her, Kurumu promptly takes it back.
  • Butterfly of Doom: In Act III, when Luna discovers that Rason is destined to die during the fight against Kiria, she promptly leaves to find a way to change his fate. Unfortunately, it's revealed in chapter 40 that Luna was supposed to be present in the original timeline during the fight against Kuyou, and save Astreal from death at Kuyou's hands; with Luna's departure, Kuyou torches Astreal with no effort. On top of it all, Falla, heartless bitch that she is, knew that Astreal was doomed to die without Luna all along and deliberately neglected to inform Luna as such until it was too late.
  • Cain and Abel and Seth: Luna, Falla, and Complica originally had this dynamic, with Falla being the Cain to Luna and Complica's Abel and Seth. Now that Falla has been replaced with a far more benevolent Alternate Self, it's been subverted.
  • Calling the Old Man Out: In the first chapter of Act IV, Tsukune calls out Issa for his borderline abusive treatment of his daughters for their actions, making it clear that he's perfectly willing to fight Issa in their defense. Issa agrees to give Akua and Kahlua a chance at redemption as a result.
  • Came Back Strong: After being seemingly killed by Hokuto during their fight in Act IV, Tsukune is revived as a full-fledged vampire by all four Shuzen sisters.
  • Came Back Wrong: In Act V chapter 29, Ceal recounts how his grandfather used Pandora's Box to bring his great-grandfather Back from the Dead, only to discover the hard way that while Pandora can bring back the body, she can't bring back the soul. Leon is not happy to discover this, as he apparently planned to use his wish to resurrect his late girlfriend Selena.
  • Can't Act Perverted Toward a Love Interest: Gin starts to shape up in Act III after becoming Kokoa's boyfriend.
  • Can't Live Without You: In Act VI chapter 35, Jovian and Jacqueline explain that, due to the nature of their spell, they need to have a master to live, and if they do not have one, they will be cursed to die, with Death itself following them relentlessly until then. Apoch and Astreal are also cursed as such, but are unaware of it.
  • Cassandra Truth:
    • In Act I, when Rason theorizes to Mizore that Tsukune hasn't chosen which one of the girls he wants to be with because he doesn't want to compromise his friendship with the other three, Mizore dismisses him until Tsukune confirms it himself.
    • In Act II, Ageha is understandably skeptical of Tsukune and co.'s claims that Rason is Kurumu's Destined One and that she was killed and brought Back from the Dead until Kurumu, having regained her memories, confirms it herself.
    • In Act III, most of the other students don't believe the stories that Tsukune and his friends beat several Fairy Tale squadrons until they witness the gang fight off Kuyou and then an entire Fairy Tale squadron firsthand.
    • In Act III chapters 6-8, Dark is completely skeptical that the Holy Lock, a seemingly simple chain, has actually sealed the ghoul away until he sees how durable it is firsthand.
  • Casual Kink:
    • In Act II chapter 33, Rason mentions that Kurumu had him bark like a dog while they were making love.
    • Ruby and Razico's love sessions heavily involve Razico's magical chains.
  • Catch Phrase:
    • Dark often remarks "I despise those who don't treat women right" when he sees someone mistreating women.
    • Whenever someone makes a comment on their relationship, Jovian and Jacqueline dismissively state, "What do we care? We're made from magic."
    • Yukari often says "Poor angel" whenever Rason passes out from Kurumu's Marshmallow Hell.
    • Apoch and Astreal often respond to Ruby talking to them with "Yes, Ms. Ruby," said in perfect unison. It's most common during the first three acts.
    • Rason quips "Pimp" to Tsukune whenever he sees more than one girl around him.
  • Catchphrase Interruptus: When Dark is about to spout his Catch Phrase to Kenzo in Act II chapter 37:
    Dark: I despise—
    Kenzo: —those who don't treat women right. I know, Dark. I've tried to live by that motto myself, but damn it, we all just don't have the willpower you have.
  • Chain Pain: Razico fights with a magically-conjured chain.
  • Chaos Is Evil: Zigzagged; Pandora loves chaos and bloodshed, but is more Chaotic Neutral than actually evil.
  • Cheaters Never Prosper: In Act VI chapter 51, after Akasha loses Hex's game and is charmed by him as a result, Falla gambles her own heart to Hex in exchange for Akasha's freedom, but uses her time powers to cheat; Hex realizes it right away and declares it an automatic loss.
  • Children Are Innocent:
    • It was being forced to kill an innocent little girl that caused Dark to turn on his former master.
    • In Act IV, Tsukune and co. manage to earn the public's trust by saving children from being killed by the collateral damage Jovian and Jacqueline are causing.
  • Chivalrous Pervert: Gin. In Act III, when he discovers from the boys that Kano had been blackmailing the girls into letting him take all manner of dirty pictures of them, he's absolutely furious and personally hunts down said pictures and burns them. After becoming Kokoa's boyfriend, he drops the "pervert" part completely.
  • Clipped Wing Angel: In Act III chapter 42, the minute Kuyou goes One-Winged Angel, he takes down all of the members of Tsukune's posse with relative ease. The "Clipped" part comes into play when a royally pissed off Tsukune reenters the fray, No Sells all of Kuyou's attacks, and takes him out in a matter of minutes.
  • Cold-Blooded Torture: In Acts III and IV, Jovian and Jacqueline eagerly do this to Felucia, both physically and sexually.
  • Collector of the Strange: As explained in Act III chapter 46, Issa is a collector of rare magical spells and artifacts, such as the Chrono Displacement spell, though he never actually intends to use them.
  • Combat Pragmatist:
    • One of Dark's favorite combat tactics is to turn invisible and stealth-kill his enemies.
    • After being unable to penetrate Jacqueline's barrier during their battle in Act IV, Astreal elects to blast apart the floor of the sundeck below her feet and subject her to a Disney Villain Death.
  • Comically Missing the Point/Skewed Priorities:
    • In Act II chapter 41, when Kurumu regains her memories of Rason and confirms the Cassandra Truth above, Ageha is initially more concerned with the fact that Kurumu lost her virginity to Rason instead of Tsukune rather than the fact that her daughter was recently murdered and brought Back from the Dead.
    • In Act III chapter 13, when it's discovered that the ghoul inside Tsukune had infected Kokoa with its essence, which caused her to rape Tsukune against her will, Felucia is more concerned over where having Kokoa rape Tsukune fits in with the ghoul's Evil Plan than anything else. Ahakon even asks her why that's the only detail she can focus on; in Felucia's defense, however, she does admit that it was a stupid question.
    • In Act V chapter 23, with Yokai Academy's festival ruined and several students dead as a result of Tsukune's bloodlust-fuelled rampage, Rin's primary concern is that the fireworks show has been cancelled.
  • Complete Immortality:
    • As a result of Pandora's Jackass Genie tendencies, Fafnir cannot be killed at all, except by Ceal's hands.
    • Moka's clone, as revealed in Act VI chapter 52. As the scientists explain to Gyokuro, they tried killing her via firing squad, decapitation, burning, freezing, and everything else, and the clone survived every single one.
  • Complexity Addiction: During the early parts of Act I, Apoch and Astreal go through elaborate schemes to test the group's power, and ultimately brainwash Rason and Dark, in order to be free of their master Ghaldin; the brainwashing attempt backfires when the sisters' inexperience with mind control spells allows Ghaldin to take control of all four of them. When all is said and done and Ghaldin is killed by Inner Moka, Tsukune flat-out tells the sisters that he and his friends would have helped them willingly from the start if they had simply asked.
  • Continuation Fic: Of the Rosario + Vampire anime. It actually seems to adapt the parts of the manga that the anime doesn't cover.
  • Contrived Coincidence: In Act V chapter 39, Moka and the others arrive at the destroyed human city shortly after Render, Leon, Apoch, Astreal, and Good!Falla's battle with Jovian, Jacqueline, and Evil!Falla has left the city in ruins; the HDA promptly uses this to blame the group for the destruction and place them under arrest. In Act VI chapter 10, after the group has escaped the HDA complex, Razico even notes that their arrival was bad timing.
  • Convenient Terminal Illness: During the final chapter of Act III, Tsukune, already about to die as a result of the cost of the Chrono Displacement spell, deliberately tears off the Holy Lock and unleashes the ghoul, which butchers Kiria. However, as the ghoul had its own mind and personality, it is destroyed instead, leaving Tsukune alive and free of its influence.
  • Cooldown Hug:
    • In Act I chapter 4, Moka tries to give Mizore one... only to get an Elemental Punch to the gut for her trouble.
    • In Act V chapter 20, when Tsukune is beginning to succumb to his bloodlust again and urges Ren and Ruby to escape before he loses control, Ren hugs him and begs him not to throw his life away.
  • Corporal Punishment/Spank the Cutie:
    • In Act V chapter 20, Kokoa mentions that Issa still spanks her, much to Gin's surprise. Later, in Act VI chapter 49, it's heavily implied that Issa spanked Akua and Kahlua to punish them for failing to stop Talon; we're not shown the actual act, but the two are left holding their butts in pain and whimpering apologies.
    • In Act VI chapter 43, when Jacqueline keeps making loud noise while they're trying to stealthily find Akua and Kahlua, Jovian promptly slaps her ass and tells her to be quiet.
    • In Act VI chapter 42, the Cii sisters reveal that their father's preferred method of punishing them was taking them out and spanking them right in front of the entire kingdom.
  • Could Have Avoided This Plot:
    • In Act I, Apoch and Astreal brainwash Rason and Dark in order to get them to help them fight off their master Ghaldin, but it backfires when Ghaldin arrives and takes control of all four of them. When Ghaldin is defeated, Apoch and Astreal apologize and insist that they only wanted help; Tsukune informs them that the entire group would have helped them willingly from the start if they had just asked and let them act on their own accord.
    • In Act VI chapters 42-44, tensions between Kokoa and Sun over Gin escalate to the point where Kokoa attacks Sun and ends up leaving her in a coma, essentially brain dead. Though he acknowledges that Kokoa is undoubtedly at fault, Gin also states that the whole mess could have been prevented if he had just been clearer with Sun and stopped her advances sooner.
  • Cover-Blowing Superpower: In Act III chapter 41, Jovian uses Force Fields and Hand Blasts to deflect Kuyou's attacks and steer him towards the academy as part of Hokuto's plan. As Jovian had previously told them that she didn't know how to use such magic, Tsukune and Ruby are naturally suspicious and follow her to the academy's secured levels, where they discover that Hokuto and Jovian had been Evil All Along.
  • Crazy-Prepared:
    Moka: Um, say Kurumu, why do you have all these outfits anyway?
    Kurumu: Well, I am a succubus after all, and I like to be both prepared and diverse with my man.
    • As revealed in Act III chapter 13, Tsukune's ghoul somehow anticipated that the group would find a way to suppress it, namely the Holy Lock, and infected Kokoa with a portion of its essence as a contingency.
    • In Act III chapter 44, after Felucia is kidnapped by Hokuto and forced to work for him, it's revealed that she anticipated that something might happen to her and left a videotape in which she gives Dark and Mizore her blessing, as well as her Love Confession.
  • Crazy Sane: Even while suffering from chrono dementia, Luna and Falla manage to have surprisingly long moments of clarity, their bouts of instability largely signified by spells of Laughing Mad and Suddenly Shouting.
  • Creature Hunter Organization: The Human Defense Agency, founded in Act V in response to The Unmasqued World, serves to protect humanity from evil monsters. Unfortunately, due to a misunderstanding, most members of the organization automatically assume that all monsters are bad. However, as of the end of Act VI, Moka and the others have won them over, and they are now allies of the group.
  • Crowd Panic: In Act III chapter 41, the entire student body has this reaction when they discover that Kuyou has returned.
  • Curb-Stomp Battle:
    • The group's initial confrontation with Kiria in Act II chapter 26 goes badly until Tsukune unleashes the ghoul.
    • After becoming a full vampire in Act IV chapter 31, Tsukune proceeds to completely decimate Hokuto. After Hokuto has gone One-Winged Angel, no less.
  • Custom Uniform/Non-Uniform Uniform:
    • Felucia wears the Yokai Academy uniform, but leaves out the neck ribbon, leaves the jacket open to expose her white undershirt, and wears a black plaid skirt as opposed to a brown one.
    • Dark, Rason, and Ahakon all wear their street clothes instead of the uniform.
  • Dangerous Forbidden Technique: The Chrono Displacement spell enables time travel to any specific time and location, but sacrifices the user's life force and dooms them to die by the next day. At the end of Act III, Tsukune and co. destroy the spell so it can never be used again.
  • Dangerously Short Skirt: Several of the angels, including Rason, have questioned whether or not the Yokai Academy girls' skirts are supposed to be so short.
  • Dark Is Not Evil:
    • Dark Kuyumaya, no pun intended. He's a Made of Evil demon with shadow-based powers, but is one of Tsukune's pals and a heroic, if tragic, character.
    • Xarai, the necro demon that aids Ceal Erres. It's a big black demon with Combat Tentacles, but is loyal to Ceal, mourns his death in Act VI chapter 38, and comforts a heartbroken Complica, even trying to stop her from using the Chrono Displacement spell to go back because it'll kill her.
  • Darker and Edgier: Than some aspects of the original manga. For example, in the manga, Miyabi never actually raped Mizore, instead groping her and stealing her first kiss.
  • A Date with Rosie Palms: In Act VI chapter 43, Jovian manages to twist this trope into a threat to get Jacqueline to be quiet:
    Jovian: If you so much as make a peep before our master says it's all clear, then I'm going to play with myself tonight and you're going to just watch.
  • Date Peepers: In Act VI chapter 41, Sun spies on Kokoa and Gin having sex. When Kokoa finds out next chapter... let's just say she doesn't take it well.
  • Dating What Daddy Hates: In Act VI, after settling into her role as Dark's guardian angel/mother figure, Arial openly disapproves of Mizore and is firmly convinced that she isn't good enough for Dark, believing that Felucia would be a better fit. However, as of the final chapter of Act IV, Arial agrees to give Mizore a chance as per Complica's final request.
  • Dead All Along: Act VI chapter 39 reveals that Akasha is in fact an undead lost soul and not truly alive, being on a Redemption Quest from the Almighty to truly earn her place in Heaven. Subverted slightly, as it's revealed as early as her appearance in chapter 19, but it's the first Moka has learned about it. Then, in chapter 51, it's revealed that Akasha is actually Back from the Dead completely.
  • Dead Alternate Counterpart: After being killed in Act III, Apoch and Astreal are replaced by duplicates of themselves from an Alternate Timeline in Act IV. Similarly, the original Falla in the mainstream timeline is killed and replaced by a duplicate of herself from the same timeline.
  • Deader Than Dead: When Felucia, Complica, and Arial come Back from the Dead in Acts V and VI, it's stated that they're essentially pure life force in a solid form, and they can still be killed; if that happens, they'll cease to exist altogether. This happens to the original Falla, Jovian, and Jacqueline after they're pulled out of Hell by Babylon.
  • Deadly Dodging: In Act V chapter 35, after being unable to break Jovian's barrier himself, Render dodges out of the way of a Laser Blade attack from Apoch, said attack breaking Jovian's barrier and allowing Render to attack her.
  • Deadpan Snarker/Danger Deadpan: Several examples, such as this exchange between Moka and Kurumu in Act IV chapter 21, after Moka gets a Close-Call Haircut from a Death Trap:
    Moka: This is crazy! I've only been awake for ten minutes and I nearly died!
    Kurumu: That's gotta be a new record for us.
    • There's also this exchange in Act VI chapter 25, when Moka and Akasha are going to negotiate with the director of the HDA:
    HDA Captain: You two are coming with us. We will escort you to the HDA command center located outside the city and you will speak to the director personally. You will have an armed escort at all times.
    Moka: I hope that doesn't include restroom breaks.
    • Jovian also gets in on the act in Act VI chapter 43 after Jacqueline starts making noise when they're trying to be sneaky:
    Jacqueline: Um, you can punish me later for it if you want, sister.
    Jovian: Somehow, I doubt you'll learn anything if I do.
    • Dark may count, but he's so consistently deadpan that it's hard to tell whether he's this or The Comically Serious.
  • Deal with the Devil:
    • In Act II, after Kurumu is killed by duplicates of Apoch and Astreal, Rason makes a deal with the Lord of Hell to bring her back.
    • In Act VI, Felucia, having nothing left to do in Hell with Jovian and Jacqueline gone, makes a deal with the Lord of Hell to help thwart Babylon's planned invasion in exchange for being allowed into Heaven.
  • Death Amnesia:
    • As part of the deal to resurrect her in Act II, Kurumu's memories of Rason and their bond are removed so as to spare her the horrors of Hell. However, a few chapters later, Kurumu manages to regain her memories.
    • After being killed by the ghoul and resummoned by Ahakon in Act III, Dark initially has no memories of what happened beforehand until Mizore triggers the Flashback Echo below.
    • In Act VI, after being resummoned by Talon, Jovian and Jacqueline have no memory of their time working for Hokuto.
  • Death by Adaptation: In the original manga, Kuyou, Hokuto, and Kiria survived the final battle with Alucard and managed to rebuild Fairy Tale. Here, all three of them are dead by the end of Acts III and IV.
  • Death by Despair: After Rason, under the influence of the Otonashi sisters, breaks up with her in Act V, Kurumu, being a succubus that needs love to live, literally dies of a broken heart. She returns from the dead shortly after, after getting a Get A Hold Of Yourself Man from the Lord of Hell.
  • Death by Origin Story: Arial was killed by Dark, which prompted him to turn against his master.
  • Defector from Decadence: Dark was once one of Fairy Tale's top agents, but when he discovered their anti-human agenda and plans to attack Yokai Academy, he turned on them. As a result, several other agents, including Kenzo and Felucia, had Heel Realizations and followed his example.
  • Defiant to the End: In Act IV chapter 31, as he lays defeated, with Tsukune about to deliver the finishing blow, Hokuto nevertheless takes the time to gloat to Tsukune that he still wins, as Alucard has been successfully resurrected.
  • Demonic Possession: As revealed in Act III, when Kokoa completed the transfusion to Tsukune, the ghoul inside his body infected her with a portion of its essence for use as a contingency plan; when the essence takes over Kokoa in chapter 12, it uses her body to rape Tsukune, attack the group, and nearly rip off Tsukune's Holy Lock to unleash the ghoul before Kokoa manages to regain control of herself, after which Dark forcibly draws the spirit out of Kokoa's body and absorbs it.
  • Despotism Justifies the Means:
    • This is part of the reason why Falla was passed over as the next chronofly queen in favor of Luna; as pointed out by their mother, Falla was "too focused on the power to use it properly." Falla even flat-out admits that she only cares about acquiring power and nothing else, not even her own family.
    • Babylon, the Big Bad of Acts V and VI. It's outright stated that all he wants is to conquer The Multiverse and rule over all worlds as their king.
  • Destination Defenestration: In Act I chapter 4, Mizore throws Moka out a window in a jealous rage.
  • Did You Just Flip Off Cthulhu?/Rage Against the Heavens: In Act IV chapter 16, Rason is so pissed off at Heaven's Aggressive Categorism of all monsters, as well as their blatant refusal to act against Hokuto's plan to destroy the world because of their laws, that he actually calls out the Almighty himself over it, accusing him of being out of his mind. The Almighty is ultimately swayed by this, but does point out that he's not happy that Rason's "out of his mind" comment.
    Rason: Almighty... are you out of your goddamned mind? How could you, Lord? How could you treat the innocent in such a way? It's not right at all! Luna helped save the world with us! Falla... this Falla, anyway, has been an angel as well in her life. She's protected a human boy from the monsters at the academy, she helped save Luna today as well! How could you? How can you just condemn them like this? Damn it, monsters are no different than humans! Hokuto is plotting to destroy everything! EVERYTHING! And here you try to kill the innocent who have only tried to stop this from happening. We're fighting to save life on Earth, both human and monster alike! And you treat us like we're the evil in the world?! I've had enough, Almighty. I've had enough with your damned rules and laws. [...] If this is how he wants to be with his world... with the innocent lives that exist down below... to treat those lives with prejudice and cruelty just because they aren't human... and to allow real evil, real monsters to roam freely, I will have no part of it!!
  • Did You Just Punch Out Cthulhu?: In Act IV, Tsukune and co. manage to defeat Alucard, whom the entire monster world long believed to be completely unkillable and unstoppable.
  • Didn't Think This Through:
    • In Act III, Gin runs to Dark and convinces him to hide him after stealing Apoch's underwear, apparently forgetting that Dark is a well-known Wife-Basher Basher. As soon as Dark finds out, however, he throws him to Apoch and Astreal.
    • In Act III chapter 16, after the group is stated to be heroes who fought off Fairy Tale, Kokoa proceeds to brag to the other students that they'll protect the school, whipping the crowd into a big frenzy:
    Kokoa: I didn't think they'd go this crazy.
    Kurumu: More like "didn't think!"
    • Throughout Act IV, Tsukune and co. expect Hokuto to pull off a full-scale attack on Yokai Academy to capture Moka, as per what happened in an Alternate Timeline. However, they fail to consider the fact that Luna and Falla, two Time Masters, were not present in said Alternate Timeline, and are completely unprepared when Hokuto goes with a Divide and Conquer tactic instead by holding Tsukune's family hostage.
    • In Act VI chapter 22, to deal the finishing blow to a monster Ceal had grounded, Fang Fang summons a phoenix, forgetting that he's doing so in the middle of his own backyard, the phoenix is powerful enough to incinerate his entire compound, and Sun, Arial, and Complica are right in its blast radius. When Ceal points this out, Fang Fang's only response is a sheepish "Oh, right;" unfortunately, by the time this is pointed out to him, it's too late, and the phoenix unleashes a wave of fire that just barely misses Complica and Arial.
    • In Act VI chapter 51, Falla uses her time powers to cheat at Hex's game, forgetting that Hex is a Reality Warper and thus would easily be able to tell.
  • Dirty Coward:
    • In Act IV chapter 18, Hitomi constantly uses her petrified victims as shields against the group.
    • In Act IV chapter 27, Tsukune outright calls Hokuto one. Since before that point, Hokuto had held Tsukune's family hostage, forced Felucia to work for him, and is continuing to let his mooks do the fighting for him, it's not unjustified.
  • Dishing Out Dirt: From Act III onwards, Yukari learns how to use her magic to control the earth.
  • Disney Villain Death:
    • A non-villain example in Act III: during the attack on Kiria's stronghold, a Fairy Tale soldier drags Yukari down an elevator shaft to her death. She gets better.
    • Later in Act III, Tsukune flings Akua off of the top of the building after she kills Moka. Again, she gets better.
    • In Act IV, while fighting Jacqueline, Astreal blows out the floor of the sundeck the former was standing on, causing Jacqueline to fall to her doom.
  • Divide and Conquer:
    • In Act I, in order to weaken Tsukune and Moka's defenses, Rarosun and Surason shapeshift into Dark and Rason and molest Kurumu and Mizore, respectively, in order to dupe Dark and Rason into fighting and killing one another.
    • In Act IV, Hokuto has Jovian and Jacqueline hold Tsukune's mother and cousin hostage in order to force the gang to split up to save them, while also forcing Moka to go with the brainwashed Felucia to Hokuto without a fight.
  • Divine Parentage: Act II reveals that Kurumu's Disappeared Dad is actually the Lord of Hell himself, though Kurumu is unaware of this until Act V.
  • Do Not Go Gentle: Upon Alucard's revival in Act IV chapter 31, despite the others insisting that Alucard is unstoppable and the world is doomed, Tsukune refuses to accept it and just go down without a fight.
  • Doom Magnet: As pointed out a few times, the constant battles the group has had to face only started when Dark and Rason enrolled in the academy.
  • Don't Call Me Sir: While he has Kokoa, Akua, and Kahlua under his servitude in Acts III and IV, Tsukune repeatedly corrects them when they address him as "master."
  • Don't Make Me Destroy You: After beating Ceal in a fight in Act VI chapter 45, Dark says a variation of this trope name:
    Dark: This fight is over. Don't make me make Complica and Falla cry by killing you just to prove my point.
  • Does Not Know His Own Strength: In Act VI chapter 42, after Kokoa snaps and punches Sun in the face, it's revealed two chapters later that Kokoa hit Sun so hard that she fractured her skull and ruptured her eyeballs, with Yukari stating that if Kokoa had hit Sun any harder, she would have completely destroyed Sun's entire head. Kokoa is instantly horrified at this, having never wanted that to happen.
  • Double Standard: Abuse, Female on Male: Played with in Act II chapter 30, in which Inner Moka takes advantage of a loophole in the Eia Dreahl to give Tsukune a nosebleed by punching him in the face. Dark, Rason, Kurumu, and Mizore all think it was a bit extreme, while Yukari is just despondent that she didn't think of doing it.
  • Double Standard: Rape, Female on Female: Averted: during Act IV, Tsukune and co. are absolutely livid to discover that Jovian and Jacqueline had been sexually abusing Felucia and Kyouko.
  • Double Standard: Rape, Female on Male: Averted: in Act III chapter 12, when the group catches a possessed Kokoa forcing herself on Tsukune, they, especially Moka, are disgusted and furious.
  • The Dragonslayer: Ceal Erres' Family Business.
  • Drama-Preserving Handicap: Throughout Act III, Tsukune is forced to hold back much of his power to avoid cracking the Holy Lock and unleashing the ghoul.
  • Dramatic Dislocation:
    • In Act IV chapter 28, the effort of using her sword to deflect Jovian's rage-fueled Wave Motion Gun attack causes Apoch to dislocate her shoulder. She pops it back into place by repeatedly slamming it against the floor.
    • In Act VI chapter 45, Dark breaks Ceal's ankle during their fight. Ceal just snaps the bones back into place.
  • Dramatically Missing the Point: In Act IV chapter 1, when Kokoa and Moka accidentally let it slip that Kokoa turned Tsukune into a ghoul, Issa doesn't particularly care that they managed to save Tsukune and reverse the transformation; he only cares that they didn't kill the ghoul on sight.
  • The Dreaded:
    • Throughout Acts II and III, the entire group, Tsukune included, is terrified of Tsukune's inner ghoul and dread the possibility of it surfacing.
    • As stated in Act V chapter 29, dragons as a whole have this reputation in the monster world, to the extent that Render and Leon question Ceal's sanity when he reveals he's a dragon slayer.
  • Driven to Suicide/Interrupted Suicide:
    • In Act II chapter 25, Mizore, believing that she is Defiled Forever thanks to Miyabi, jumps off of a balcony in despair, but Kurumu saves her and comforts her, pointing out that Dark only wants to be with her and no one else.
    • In Act III chapter 1, after being tricked into giving Tsukune's ghoul side enough power to take over Tsukune's body, Kokoa is so horrified and guilt-ridden that she tries to jump off a cliff and into the sea, but Gin stops her and talks some sense into her.
  • Dual Wielding:
    • Render's Weapon of Choice is a pair of magically-summoned swords.
    • From Act III onwards, Mizore trades in her ice Wolverine Claws for a pair of ice katanas.
  • Dude, Where's My Respect?:
    • Much of the conflict between Mizore and Arial in Act VI revolves around this. Mizore has been nice to Arial in an attempt to get on her good side and even saved Arial's life, and Arial still treats her with contempt.
    • On more than one occasion, Falla is understandably irked that the others repeatedly fail to mention that she was instrumental in Tsukune's defeat of Alucard.
  • Dull Surprise:
    • In Act II chapter 26, Tsurara takes the revelation that Dark is an ex-member of Fairy Tale in stride, remarking that, since he was able to take out their weapons and vehicles so easily, he must have had some training with them.
    • In Act III chapter 12, the group come across a possessed Kokoa having her way with Tsukune; while the others are completely taken aback, Dark's response is a totally deadpan "Didn't See That Coming."
  • Dwindling Party: Tsukune and co. go through this in Act III chapters 47-50 during their raid on Fairy Tale's HQ. In this order: Dark is infected with Blackheart and kills Mizore, and is only stopped when Gin blows them both up using Fairy Tale's explosives; Ruby is fatally shot by a Fairy Tale agent; Yukari is dragged to her death down an elevator shaft by another agent; Ahakon gets blown up by a grenade while fighting a group of soldiers; Rason is shot down by a Fairy Tale gunship; Kurumu is gunned down by two other gunships after taking out the ship that killed Rason; Kokoa's overcharge sets off a gas explosion while fighting Kahlua, killing them both; and Moka dies when Akua punches through her chest and destroys her heart, with Akua being thrown off the building to her death by Tsukune immediately afterwards. By the time Tsukune reaches Kiria, he's all alone, and gets curb-stomped by Kiria only to be saved by Luna, whom Tsukune convinces to let him use the Chrono Displacement spell to send him back in time by one day and save everyone.
  • Easily Forgiven/Turn the Other Cheek: The various members of Tsukune's circle of friends can do such things as nearly kill each other and pick fights for the pettiest of reasons, and by the end of the day, Tsukune will have forgiven them and gotten them to forgive each other.
  • Eek, a Mouse!!: In Act I chapter 25, Apoch freaks out at the sight of a bug, much to Astreal's annoyance.
  • Elemental Powers: Ahakon is able to cast fire, water, and lightning magic.
  • Embarrassing Nickname: When he summons him in Act III, Ahakon dubs Dark "Amazing Joe." As soon as Dark regains his memories, he immediately threatens to kill Ahakon if he calls him that again.
  • Energy Bow: In Act VI, Astreal learns the Artimus Arrow spell, which is essentially this.
  • Engagement Challenge: In Act VI, Arial, who has been acknowledged as Dark's mother in a sense, outright disapproves of Mizore's relationship with Dark and tells her that she will have to prove herself worthy of Dark's hand in marriage. Just a few chapters later, however, she decides that Felucia would make a better wife to Dark than Mizore, and is actively shipping Dark and Felucia together. As of the end of Act VI, however, she agrees to give Mizore a fair chance as per Complica's Last Request.
  • Entitled to Have You: Arial's attitude towards Dark for most of Acts V and VI, to the extent that she's perfectly willing to endure all manner of threats, physical harm, and even the wrath of the Almighty Himself because she's convinced that Dark is rightfully hers.
  • Eureka Moment: In Act III chapter 42, with the revelation that Fairy Tale is still active and coming to attack Yokai Academy, Tsukune remarks to Moka that Akua and Kahlua said that Fairy Tale had been destroyed. At that very moment, Moka recalls the mystery vampire agent they fought in Ashton City during Act II, and from the evidence she failed to put together before (namely the agent's fighting style, voice over the radio, personal knowledge of Moka, and the fact that Akua just happened to show up at the academy right after the gang got back from Ashton City), realizes that Akua was said vampire agent; thus, Akua and Kahlua have been working for Fairy Tale all along.
  • Exact Words:
    • In Act II chapter 30, Inner Moka uses the exact wording of the Eia Dreahl to her advantage, realizing that the pact only said to give Tsukune a nosebleed; it didn't say how.
    • In Act III chapter 9, according to the elder in Heaven, the Holy Lock can withstand almost anything on Earth. Key word, almost: even it can't take the strain of Tsukune's full monster energy without cracking.
    • In Act III chapter 44, the gang accuses the headmaster of lying when he said that Fairy Tale was destroyed. However, Mikogami points out that he only said that the dark lords had informed him that Fairy Tale had disappeared and that they wanted the school reopened; he never explicitly said that the organization was destroyed.
    • In Act VI chapter 2, after knocking Ran senseless with a multitude of washtubs, Yukari agrees to respect Ran's feelings and not to hit her with any more of them. However, as she points out, she never said she wouldn't use her earth powers to bury Ran alive if she inflicts Marshmallow Hell on Ahakon again.
  • Expendable Clone Army: In Act II, Fairy Tale uses the spell that originally created Apoch and Astreal to create a small army of duplicates, which they use for, among other things, living weapons, combat tests, and even sex toys.
  • Explain, Explain... Oh, Crap!:
    • In Act III chapter 46, Kou is explaining to the headmaster that the Chrono Displacement spell that Fairy Tale stole was stored in a secret archive on the Shuzen family estate that only Issa and his daughters knew about... and then realizes that the only way Fairy Tale could possibly have known about the spell or the archive is if Akua and Kahlua were working for them.
    • In Act VI chapter 13, Kyouko insists that Talon can't be evil because he's targeting those who were part of Fairy Tale... and then realizes that since Dark, Akua, and Kahlua are ex-Fairy Tale agents themselves, they're on Talon's hit list too.
  • Extreme Melee Revenge:
    • In Act II; upon discovering that Miyabi had raped Mizore, Dark goes ballistic; when he gets the upper hand, Dark slowly crushes all of the bones in Miyabi's arms and legs to powder before tearing them off one by one, punches him in the face with such force that his jawbone snaps clean off, and finally tears his spinal cord clean out of his body with his bare hands. Even though Tsukune and co. all agree that Miyabi deserved every minute of it, they're still horrified at Dark's brutality.
    • In Act III chapter 12, after catching Kokoa raping Tsukune, Moka flies into a rage and promptly pummels Kokoa into the ground while demanding to know why she did it. Midway through, she discovers that Kokoa has been infected by the ghoul's essence, which promptly seizes control of Kokoa again and beats Moka down right back.
  • Extreme Omnivore: Chronoflies are able to eat literally anything to keep their strength up; Luna and Falla have eaten, among other things, pencils, rocks, silverware, blankets, and their own gym clothes. In Act III chapter 31, Luna takes this trope to extreme levels by eating the entire back half of Kano's head.
  • Even Evil Has Loved Ones:
    • Despite being a Disappeared Dad, the Lord of Hell does care about Kurumu. Upon her temporary death in Act II, he allows her memories of and bond with Rason to return even though part of the Deal with the Devil was that they would be permanently removed, and then goes Papa Wolf on the ogres who began to rape and torture her soul before she was revived.
    • In Act IV, Jovian is absolutely furious when Astreal kills Jacqueline.
  • Everyone Has Standards/Even Evil Has Standards:
    • The Lord of Hell himself has some. He does not approve of Babylon's plan of conquest, and arranges for Felucia to be resurrected and earn her place in Heaven in exchange for helping to stop said plan.
    • According to Dark, even the most evil denizens of Hell find harming children abhorrent. It was being forced to kill one by his former master that motivated him to turn on said master.
    • In Act VI chapter 42, while Kurumu admits that the myth that succubi can drain the life force out of men during sex is true, nowadays a succubus would have to "be a bitch" to do so; her mother never killed any of her various flings, and she never planned to either. As Kurumu puts it, "we may be demons who prey on men, but we're classier than doing something as dark as that."
  • Everything's Better with Princesses:
    • Luna, Falla, and Complica are princesses of the fallen chronofly kingdom.
    • As the daughter of the Lord of Hell, Kurumu is in effect the Princess of Hell.
  • Evil All Along:
    • In Act I, Rarosun and Surason Kiyo initially appear good, even befriending Apoch and Astreal. Then it turns out they're working for the vampire lord Dahlzin, who wants to drink Tsukune and Moka's blood to become stronger, and pull off a Divide and Conquer tactic on their friends to leave the two open.
    • Act III sets up Hokuto as benevolent and a friend to the group. As it turns out, he infiltrated Yokai Academy in order to steal an Artifact of Doom as part of his plan to resurrect Alucard, and even orchestrated Kuyou's attack on the school to distract everyone while he did so.
  • Evil Cannot Comprehend Good:
    • During Act IV, while mentioning Felucia's disappearance and Luna's death at her hands, Evil!Falla is completely unable to understand why Mizore and Kurumu, respectively, are upset over them because they were sort-of rivals for Mizore and Kurumu's respective boyfriends. After bifurcating Luna in Act IV chapter 13, Evil!Falla flat-out tells Kurumu to her face that Kurumu should thank her for doing so since Luna won't be hounding Rason anymore.
    • As a Straw Nihilist, Hokuto is completely incapable of believing that humans and monsters could ever peacefully co-exist, and even deliberately breaks The Masquerade to prove to Moka that the humans would never accept monsters. He's firmly convinced that the humans in Tsukune's neighborhood will kill Tsukune and his friends without even trying to listen to reason, and is absolutely surprised when the group actually manages to win said humans' trust, with Moka even taking the time to mock Hokuto for his "failed hypothesis."
    • As noted in Act VI chapter 53, Gyokuro is literally incapable of imagining a world where humans and monsters peacefully coexist. To her, humans are a plague, and the very idea of human/monster coexistence is, in her words, a "foolish notion" and a "despicable dream."
  • Evil Counterpart: Jovian and Jacqueline Kikion, two duplicates of Apoch and Astreal Ezrana enhanced by Alucard's blood. Like the Ezranas, they're Artificial Humans created by magic, both being able to shoot energy blasts and create Force Fields, though theirs are far more powerful. Unlike Apoch and Astreal, however, they're batshit insane and work with Hokuto in his plan to resurrect Alucard and destroy the world. Also unlike Apoch and Astreal, who have a strictly familial relationship, there's quite a bit of Twincest involved. The new Jovian and Jacqueline that are summoned by Talon in Act VI are considerably more sympathetic and friendly.
  • Evil Gloating: In Act I chapter 30, after trapping Kurumu and Mizore behind a barrier while Rason and Dark are fighting, the Kiyo brothers proceed to gloat to the two that they were the ones who molested them while in Rason and Dark's forms, and the plan was made even easier because the girls were gullible enough to believe it.
  • Evil Is Not a Toy:
    • In Act III chapter 52, Kiria discovers this the hard way when Tsukune unleashes the ghoul, which Kiria proceeds to try and control; he's swiftly torn apart.
    • Gyokuro creates Discord, a clone of Luna enhanced with a quadruple dose of Blackheart, with the intent of making a new Alucard under her control to wipe out humanity. If the preview for Act VII, posted at the end of Act VI, is any indication, Discord will end up destroying the entire universe within a week upon completion.
  • Evil Is Petty:
    • Falla killed her parents, destroyed her homeland, and wiped out the entire chronofly race (with the exception of herself and Luna) simply because she was jealous that Luna was chosen to be the next queen over her.
    • As revealed in a flashback in Act IV chapter 29, Felucia, before her Heel-Face Turn, once stole a car, nearly killing two human teens in the process, simply because it matched her eyes.
  • Evil Sorcerer: Ghaldin Rayazo, Apoch and Astreal's former master.
  • Evil Wears Black: Babylon's Elite Mooks, such as Rathieal, all wear black, as do Jovian and Jacqueline.
  • Eye Scream: Falla lost her left eye in a fight with Luna in the past. In Act V, when the original Falla returns, Ceal tears her remaining eye out and uses it to replace the new Falla's lost left eye.
  • The Faceless: All we ever really see of Xarai the necro demon are his Combat Tentacles.
  • Failed a Spot Check: In Act IV chapter 17, Falla mistakes a bottle of Yukari's love-struck potion for perfume, completely failing to notice the warning note Ruby left next to it.
  • Failure Is the Only Option: In Act III, Hokuto insists that Kiria's plan to rewrite history with Chrono Displacement was doomed from the start, because he got the idea from manga. He's proven right during the final chapters: if Tsukune had failed to stop him, Luna, insane with grief, would have killed Kiria herself and then let the Chrono Displacement spell destroy the world, while in the mainstream timeline in chapter 52, Tsukune deliberately unleashes the ghoul and kills Kiria.
  • Fake Ultimate Hero: Invoked; throughout Act III, many of the other students believe Tsukune and his friends to be this. They're proven wrong when the entire school witnesses the gang fight off Kuyou, and then a battalion of Fairy Tale soldiers.
  • Fallen Angel:
    • Rason himself is one. His backstory reveals that he fell from grace as part of an agreement with his superiors to prove that not all monsters are evil.
    • In Act VI, Rason's friend and fellow angel, Gabriel, also loses his grace as part of losing a bet with Hex.
  • Fantastic Slur: Act II onwards uses the term "slushy" as a racial slur against Mizore's species.
  • Fatal Flaw:
    • Arial's flaw seems to be her stubbornness and Hair-Trigger Temper. She spends most of her screen time in Acts V and VI obsessed with Dark, and repeatedly brushes off any and all attempts to reason with her until she causes Dark a Heroic BSOD that nearly leads to his death.
    • From the viewpoints of his friends, Tsukune's flaw is his tendency to constantly forgive those who tried to kill him and give them a second chance. When he decides to do so with Akua and Kahlua, Dark flat-out tells him that it will be the death of him someday.
  • Female Angel, Male Demon: Inverted; Rason is a male angel, Kurumu is a succubus.
  • Flashback Echo:
    • In Act III chapter 4, when a Fairy Tale spider demon steals a re-summoned Dark's linked bracelet from Ahakon and forces him to attack Mizore, Mizore tells him, "I don't hate you. It's not your fault," which was the very same thing Arial Kuyumaya said to him before he was forced to kill her. Dark instantly regains his memories as a result and kills the spider.
    • Later, in Act III chapter 17, when Luna says to Rason, "I didn't think angels in Heaven cared about us monsters," Rason has one and realizes that Luna was the same monster girl he saved from a human rapist.
  • Flipping the Bird: In Act III chapter 52, Tsukune flips Kiria off after giving him a combination Big "Shut Up!"/Precision F-Strike.
  • Flower in Her Hair: From the climax of Act III onwards, Ruby wears a black rose in her hair. It was given to her by her Love Interest Razico.
  • For the Evulz:
    • In Act III, this is essentially the only reason Kuyou burns Astreal alive.
    • The original Jovian and Jacqueline who served Hokuto revel in committing mass murder, tormenting people, and blowing things up just for kicks. Among other things, they hold Tsukune's cousin Kyouko hostage and rape her, and then taunt Tsukune about it over the phone, and blow up Tsukune's house just to torment him; they would have killed his mom in doing so if Gin hadn't gotten her out in time. While they're often acting under Hokuto's orders, there's no doubt that they enjoy doing committing acts of evil for the sake of it, and their brief revival via Babylon in Act V proves once and for all that they don't even need Hokuto to be evil.
    • The new Jovian and Jacqueline who serve Talon in Act VI, while considerably less sadistic and cruel than Hokuto's, aren't above indulging in this either; in Act VI chapter 43, when they're looking for Akua and Kahlua in the Shuzen castle, Jacqueline suggests that they just blow up the castle, leading to this exchange:
    Jovian: Why is it that whenever we can't find somebody your first instinct is to blow up everything around you?
    Jacqueline: Because it's fun.
    • In Act VI chapter 25, it's mentioned that during their time enslaved to Babylon, Rathieal regularly abused the Otonashi sisters and tortured them with their Slave Collars just for laughs.
  • Forced to Watch:
    • During Act I chapter 30, after Rarosun and Surason reveal how they duped Rason and Dark into fighting each other, they decide to make Kurumu and Mizore watch as their respective boyfriends kill each other, even morphing into the two to egg the boys on. It backfires when Rason and Dark see through their disguises.
    • During the climax of Act IV, Hokuto decides to force Moka to watch as Jovian and Jacqueline break The Masquerade while battling Tsukune and the others, and then watch the humans the gang had sworn to protect kill the gang in cold blood. This plan backfires when they actually manage to win the humans' trust.
    • In Act V chapter 34, the dark Falla makes Render and Leon watch as she rips the good Falla's wings, arm, and leg off.
  • Forceful Kiss:
    • In Act III chapter 31, Kano really starts becoming unlikable when it's revealed he forced Kokoa to make out with him.
    • In Act VI chapter 27, Arial's infatuation with Dark reaches its critical point when she kisses him. Having already been suffering a Heroic BSOD upon discovering that Arial was in love with him, Dark absolutely freaks out at this.
  • Forgot About His Powers:
    • In Act I chapter 12, after being thrown out a window, Ruby is initially prepared to die and freaking out... only to remember she can fly and save herself.
    • In Act III chapter 13, Apoch and Astreal try to help Ruby repair the damaged parts of the school, only to cause an explosion that causes even more damage, after which Ruby angrily reminds them that they don't know how to fix things with magic; the two sheepishly admit that they forgot that detail.
  • Friend to All Children: Sun easily befriends and bonds with Arial and Complica in Acts V and VI. In Act VI chapter 22, it's the sight of Sun saving the two from Babylon's monsters that convinces Ran that Sun wasn't the one who destroyed their hometown.
  • Friendless Background: In Act VI chapter 16, it's revealed that Arial had a difficult time making friends due to her temper.
  • From Bad to Worse:
    • In Act III chapter 10, Tsukune discovers that his Holy Lock cracked under the pressure of his aura. In the next several chapters, he ends up cracking five more links in the process of stopping threats, and all before the new school year even starts.
    • In Act III chapters 40-42, Kuyou attacks the school and kills Astreal, and Tsukune breaks all but one link of the Holy Lock while fighting him, whereas Apoch is killed by Jovian under Hokuto's orders after Hokuto and Jovian reveal their true colors, and Felucia is kidnapped by Hokuto and extorted into working for him. And if that wasn't bad enough, almost as soon as Kuyou is dealt with and Hokuto flees, Kiria sends a massive Fairy Tale armada to the school to capture Tsukune, Moka, and Kokoa.
  • General Ripper: Jenner Rythmore, the head of the Human Defense Agency founded in response to The Unmasqued World in Acts V and VI. He's a blatantly anti-monster Jerkass who makes no effort to hide his open distrust of monsters, going so far as to accuse them of setting up Alucard's attack during the climax of Act IV just so they could kill him and make themselves look like heroes, and in Act V chapter 20, even openly states that he's just waiting for an excuse to declare open war on the monster world. In the early chapters of Act VI, the gang ends up killing Jenner in self-defense, and he is subsequently replaced by Hothorne Tamaka, who is far more of a Reasonable Authority Figure than Jenner ever was.
  • Generic Doomsday Villain: Tsukune's ghoul form has no interest in taking over the world; it simply wants to hijack Tsukune's body and then kill and/or rape anyone and everyone unfortunate enough to get in its way. This is proven at the end of Act III chapter 52; when Tsukune unleashes it, Kiria tries to persuade it to help him in his Evil Plan, and promptly gets both dismembered and disemboweled for his efforts.
  • Gentleman Thief: Razico, though he prefers to be called a treasure hunter. He quickly manages to win Ruby over, and when hired to steal Lilith's Mirror in Act IV, he remarks after the mirror wreaks havoc that he didn't know it was dangerous and never wanted anyone to get hurt. He actually admits that part of the reason he raided the archives at Yokai Academy was an excuse to see Ruby again. In Act V chapter 4, when the headmaster gives him a mission to track down Pandora's Box before it falls into the wrong hands in exchange for any treasure he desires, Razico requests that Ruby be freed from her life debt to the headmaster.
  • Giant Flyer: The rylos, giant birdlike storm demons in Babylon's army which are described as being at least as big as Alucard.
  • The Gloves Come Off:
    • Whenever Dark removes his headphones and MP3 player, it's a sign that he's about to get serious.
    • In Act III chapters 41 and 42, the gang (minus Tsukune) is doing relatively well against Kuyou at first, but only because, as Moka points out, Kuyou hasn't even really been trying. Sure enough, Kuyou goes One-Winged Angel soon after Moka says this and makes short work of everyone... until Tsukune reenters the fray and annihilates him.
  • Glowing Eyes of Doom/Power Glows:
    • Both Rason's eyes and wings glow when he uses his powers.
    • Whenever Astreal is about to fire a Hand Blast, her arm glows red.
  • God: Here, God is referred to almost exclusively as "the Almighty" and has yet to make a physical appearance.
  • A God I Am Not: As Hex explains in Act VI, for all of their power, he, Pandora, and Babylon are still mortal and can bleed and die just like anyone else.
  • God Is Flawed: The Almighty is depicted throughout the first three acts, as well as the first third or so of the fourth, as being strictly pro-human/anti-monster, with most angels being shown in a similar fashion. However, by Act IV chapter 16, the Almighty is moved by Rason's willingness to die for his belief that monsters can be good just like humans, and by the end of Act IV, monsters are being accepted into Heaven as well.
  • The Gods Must Be Lazy: The Almighty and the angels have yet to actually directly intervene in the various battles throughout the series, neglecting to aid Tsukune and co. against Fairy Tale and Alucard. Rason even takes the time to call them out on it in Act IV chapter 16.
  • Godzilla Threshold: In Act II, Tsukune becomes so desperate to save Kokoa from a lethal Super Power Meltdown that he deliberately lets the ghoul take over his body to help.
  • Gone Horribly Right:
    • In Act I chapter 12, Apoch and Astreal brainwash Rason and Dark for aid, only for their master to exploit this and use all four of them as his mindless slaves.
    • In Act I chapter 23, Yukari, hoping to help Tsukune and Moka's relationship, creates a special Love Potion that literally makes someone dosed with it crazy with love; as Yukari puts it, "you may not want to be in public then." However, Yukari never anticipated that Moka would share the potion with Kurumu and Mizore during school hours, rather than use it for herself when she and Tsukune are alone.
    • Talon Ryashen's backstory. He was kidnapped off the street by Fairy Tale and turned into a Super Soldier. The minute the experiments were complete, he escaped the lab and now seeks to wipe out anyone and everyone who ever worked for Fairy Tale as revenge for the loss of his humanity.
  • Good Is Not Nice: Ceal Erres fits this trope to a T. While he is a fundamentally good person, he's also a big-time Jerkass who often gripes when asked to heal the others; at one point, the others have to literally beg him for help when Dark is badly injured.
  • Good Wings, Evil Wings/Winged Humanoid:
    • Angels such as Rason and Gabriel have generic white feathered wings. After losing his grace in Act VI to Hex's game, Gabriel briefly loses his wings, but they are restored by Ceal with black feathers.
    • Succubi such as Kurumu have bat wings.
    • In Act IV, Astreal learns to manifest energized wings via a flight spell.
    • Chronoflies all have colorful butterfly wings.
    • Arial, now a snow angel, has wings composed of icy feathers.
    • Several of Babylon's Elite Mooks, such as Rathieal, have black feathered wings as well.
  • Good People Have Good Sex/Sex God: In Act II chapter 32, when Kurumu, Moka, and Mizore consummate their relationships with their respective beaus, they all describe the experience as such. Mizore particularly stands out, as she remarks that having sex with Dark was such a powerful experience that she passed out from the pleasure more than once.
  • Gosh Dang It to Heck!: Under normal circumstances, Luna is too polite and refined to swear, to the extent that, in Act IV, Tsukune and co. are genuinely shocked to hear her drop F-bombs.
  • Gotta Kill Em All: As revealed in Act VI chapter 53, this is what Gyokuro's Evil Plan involving the Blackheart-enhanced clones of Luna and Tsukune's former harem amounts to. First, she will use the clones of Moka, Mizore, Ruby, Kokoa, Kurumu, and Yukari to destroy the originals, as well as everyone and everything they hold dear. Then, when they and the "foolish" notion of human/monster coexistence has been crushed once and for all, she will unleash Luna's clone upon the world to subjugate humanity.
  • Great Offscreen War: Act III mentions the Battle of Kahdaln, the Last Stand during a war between monsters and humans for control of the world; the monsters lost and were forced back into the monster world, thus beginning The Masquerade. In the present day, most monsters dislike talking about it to the extent that, when Ahakon brings it up in class, Ms. Nekonome promptly dismisses it as a myth.
  • Green-Eyed Monster: In Act I chapter 4, Mizore gets so jealous of Tsukune's attention to Moka that she attacks Moka in a rage.
  • Groin Attack: A Rare Female Example; in Act IV chapter 6, it's heavily implied that Jacqueline uses her magic to fry Felucia's crotch while torturing her.
  • Guns Are Worthless: Defied; when Tsukune expresses confusion over why his monster friends are scared of guns, they explain that, monster or not, headshots are fatal to anything. Mizore even explicitly says at one point that the entire reason the students at Yokai Academy are being taught to co-exist with humans is because human technology and weapons are actually more powerful and numerous than monster might and magic.
  • Hair-Trigger Temper: Arial is noted by several characters to have a foul temper. She doesn't help matters by lashing out whenever someone points it out to her.
  • Half the Man He Used to Be:
    • In Act IV, after getting her powers back, the first thing Falla does is slice Luna in half. Several chapters later, an Alternate Timeline duplicate of Luna saves the original and takes her place.
    • In Act IV chapter 19, after kicking Hitomi's ass, Inner Moka steps back and allows Apoch to finish her off by chopping her in two.
    • In Act IV chapter 28, Apoch finishes Jovian off by slicing her in two at the waist.
    • In Act V chapter 36, Leon, after mimicking Jacqueline's powers, kills Jacqueline by completely vaporizing her from the waist up with a point-blank Wave Motion Gun.
  • Hand Blast/Power Palms: Astreal's primary method of attack is a red energy beam shot from her palm.
  • Hannibal Has a Point: In Act IV chapter 24, Hokuto's insistence that Yokai Academy's lessons are less about co-existence and more about hiding amongst the humans does make sense in retrospect, even if Moka denies it.
  • Harmful to Minors:
    • Yukari faints upon witnessing Dark's Extreme Melee Revenge on Miyabi in Act II.
    • Likewise, after Dark uses a belt sander on a bully's face in shop class in Act III, Ahakon is completely traumatized.
    Ahakon: So much blood... so much blood...
  • Hates Being Touched: Rathieal. In Act VI chapter 21, when his fellow soldier Sivia does so one too many times, he snaps and kills her with his bare hands.
  • Hawaiian-Shirted Tourist: Leon Takeda often wears a blue Hawaiian shirt.
  • He Who Fights Monsters:
    • In Act I, Astreal dips into this territory when she decides to brainwash Rason and Dark to force them to fight Ghaldin for her and Apoch. When Apoch points out that they'd be stooping to Ghaldin's level by doing so, Astreal insists that it's not the same because Ghaldin used the two of them to kill whenever and whoever he wanted, while they won't use the boys for such actions.
    • In Act VI, Talon is dipping into this territory quite well. The members of Fairy Tale who were actually responsible for his transformation are already dead, but he doesn't care; as far as he's concerned, everyone who was ever a member of Fairy Tale, including Unwitting Pawns and those who left willingly, is equally guilty, even Dark, who was one of the heroes who took down Alucard. In Act VI chapter 35, Akua and Kahlua even flat-out tell him to his face that he's no better than those who made him what he is.
  • Headphones Equal Isolation: Dark and Arial constantly listen to music on an MP3 player to the extent that they largely "hear" through lip-reading.
  • Heel Realization: At the end of Act III, Kahlua and Akua have one when they discover that Kiria's plan to rewrite history with Chrono Displacement would have only benefited him, and that he would have infected them with Blackheart and sent them back in time to kill their father as part of said plan.
  • Hero with Bad Publicity: In Act VI, Tsukune's group has become this thanks to Van Helsing Hate Crimes, though they are making progress.
  • Heroes Prefer Swords: As revealed in a flashback in Act IV chapter 30, Dark managed to take out both an army of anti-Fairy Tale monsters and a necromancer on separate occasions using only a sword. Of course, this doesn't mean that he Doesn't Like Guns.
    Felucia: Dang, he's got some fancy tastes in weaponry.
  • Heroic Neutral: The snow people in Mizore's village are described as such in Act II, preferring to stay out of conflicts.
  • Hey, You!: With the exception of Falla and Complica, Ceal has yet to actually address the other members of the group by name, instead calling them by their species ("succubus," "angel," shadow demon," etc.), or in Leon and Render's case, their professions ("hunters.").
  • Hope Spot:
    • In Act III, Hokuto arranges for Jovian to repair Tsukune's Holy Lock to give him a chance against Kuyou. What Hokuto and Jovian don't tell the group is that the repair work is only temporary, and once the spell wears off, all of the links Tsukune had broken before will break again, along with any other links that Tsukune strains in the meantime; indeed, right in the middle of the fight against Kuyou, the spell wears off and all but one link of the Holy Lock cracks.
    • A brief moment in Act VI chapter 42 between Mizore and Arial; in an attempt to bond with Arial and win her approval, Mizore asks her how Dark was when she first met him. Arial softens toward her for a few brief moments to tell her the story... and then goes right back to her "Mizore isn't worthy of Dark" mentality as soon as she's done, much to Mizore's irritation.
  • Hopeless Suitor:
    • Apoch and Astreal are this to Dark and Rason, respectively.
    • Kokoa was one to Dark and then Tsukune before getting over it.
  • A House Divided: Throughout the first few chapters of Act III, the ghoul inside Tsukune causes a schism within Tsukune's posse, with some (Moka, Kurumu, and Rason, for example) trusting Tsukune to keep the ghoul contained with the Holy Lock and others (Dark, Mizore, and Felucia, for example) firmly convinced that the ghoul will return eventually. They all get over it when they discover just how sturdy the Holy Lock is.
  • How Much More Can He Take: In Act II, when Dark has Miyabi at his mercy, he proceeds to, in this order, crush all of the bones in his arms and legs to powder, tear off said limbs one by one, punch Miyabi's jaw clean off, and then finally tear out his spine. Up until the very moment Dark tears out his spine, Miyabi is still alive and conscious.
  • Hulking Out: In his battle form, Render triples in muscle mass.
  • Humans Are the Real Monsters:
    • Talon Ryashen of Act VI believes this, explicitly telling Kyouko that she's lucky to be stranded in the monster world; he even quotes the trope name word for word. It's later revealed that he came to believe this after he was turned into a monster hybrid by Fairy Tale, after which his family promptly rejected him in disgust.
    • In Act VI chapter 25, Moka and co. call out the HDA for their Van Helsing Hate Crimes mentality on monsters, pointing out that they treat all monsters as evil beasts the minute a single rogue monster acts out while ignoring the fact that humans can be just as bad. Mizore even explicitly tells them in disgust that the HDA themselves are more of monsters than the gang. This reaches the HDA director, who agrees to negotiate with Moka and Akasha peacefully.
  • Humanity Is Superior: This is noted to be the very reason that the dark lords started The Masquerade in the first place; it's noted on multiple occasions that as powerful as monsters are, humankind outnumbers monsters a thousand to one at the very least, and human technology and weapons are superior to monster might and magic.
  • Humanoid Abomination: Discord, the Blackheart-enhanced clone of Luna created by Fairy Tale in Act VI chapter 53, whom Gyokuro intends to essentially be a new Alucard under her control.
  • Hypocrite:
    • In Act I chapter 20, Dark calls Kokoa out on this, pointing out that she's insisting that Tsukune isn't worthy of being with a vampire because he isn't as strong as Moka is, but is still insisting that Dark is worthy of being with Kokoa herself despite having lost to Inner Moka in a fight. When Kokoa proceeds to declare that it's different because Dark is a stronger fighter than Tsukune and protects those around him, Dark quickly turns her logic against her by pointing out that, even before Tsukune got vampire powers, he risked his life to protect his friends again and again before proceeding to remark that, not only is she being unfair to Tsukune, she's still chasing after Dark even though he's already chosen Mizore as his girlfriend; when Kokoa decides to actually beg Dark not to reject her, Inner Moka then calls her out over the fact that, after all of her talk about vampire pride, she Ain't Too Proud to Beg Dark to be with her even though he's already made his choice. Kokoa realizes that everything they both said is true, and is left in tearful remorse.
    • In Act IV, most other members of the group reject Akua and Kahlua because they worked for Fairy Tale and nearly killed them, while forgetting that Dark himself once worked for Fairy Tale and has committed atrocities just as bad, if not worse. When Dark calls them on it, the others agree to at least give Kahlua and Akua a chance.
    • For all of Fairy Tale's claims that they're looking out for monsters, they also spend quite a bit of time killing their fellow non-humans, having personally destroyed Ahakon's village and killed everyone there, nearly doing the same to Mizore's hometown not once, but twice, and also directly attacking Yokai Academy for preaching human/monster co-existence.
    • In Act VI chapter 20, Arial criticizes Ran for chasing after Ahakon and refusing to accept him as taken when she herself is/was the same way with Dark. She also has the gall to call Kokoa out over her Hair-Trigger Temper when Arial's own temper is just as bad, if not worse. To top it all off, in chapter 46, when she accepts that Gin loves Kokoa and not Sun, she still fails to see the similarities between their relationship and Dark and Mizore's.
    • Talon Ryashen in Act VI. He seeks revenge on everyone who ever worked for Fairy Tale for turning him into a weapon, but as pointed out by others, he resummoned Jovian and Jacqueline and is using them as weapons to achieve this goal. Talon adamantly denies this, insisting that he summoned them for them to work together, and doesn't want them to be his slaves.
    • Invoked in Act VI chapter 30; when Hothorne asks Moka how he can trust her story on Babylon's invasion, Moka turns it around on him by pointing out that, since his organization has a tendency to automatically deem all monsters evil, he has little room to talk to them about trust issues.
  • I Cannot Self-Terminate:
    • In Act III chapter 12, Kokoa begs Moka to kill her before her ghoul infection takes over completely.
    • In Act III chapter 43, as Fairy Tale attacks the school, Tsukune forces the others to promise to kill him in the event that the Holy Lock breaks completely and the ghoul is unleashed again.
  • I Did What I Had to Do: Inner Moka's response to the Double Standard: Abuse, Female on Male example above:
    Inner Moka: I had to do what needed to be done.
  • I Don't Want to Ruin Our Friendship: In Act I, Rason himself speculates to the members of Tsukune's Unwanted Harem that perhaps he hasn't chosen which one he wants to date because he doesn't want to ruin his friendship with the other four. Tsukune himself confirms this, and all five of them are instantly ashamed of themselves for putting him in such a position.
  • I Know Mortal Kombat: While preparing for the school dance at the end of Act I, Moka learns how to dance by playing Dance Dance Revolution.
  • "I Know You're in There Somewhere" Fight: In Act III chapter 12, this is what Tsukune's fight with the ghoul-infected Kokoa amounts to. He manages to get through to Kokoa in the end.
  • I Let You Win: In Act I chapter 20, Dark has a friendly fight with Inner Moka in an effort to prove a point to Kokoa and get her to stop pursuing him and stop being such a Jerkass to Tsukune; he ends up throwing the fight.
  • I Lied:
    • In Act II, Miyabi forces Mizore to have sex with him in return for sparing her mother's life... only to order Tsurara's death shortly afterwards to teach the snow women "their place."
    • In Act V, after promising the Otonashis their freedom if they bring him the ones who killed Alucard, he goes back on his word when he finds out that they missed Razico (the deal being they charmed everyone who beat Alucard), before remarking that he most likely never would have let them go anyway.
  • I Owe You My Life:
    • In Act V chapter 20, Ren uses this trope as her reason for staying with Tsukune to help him with his bloodlust, as he and the others saved her from Babylon's enslavement. Akua admits much the same, considering he was willing to give her a chance despite her actions under Fairy Tale and help her redeem herself.
    • In Act VI, Fang Fang agrees to help the group in part because they busted him out of the HDA facility.
  • I Want My Beloved to Be Happy:
    • Despite losing the Eia Dreahl to Moka in Act II, Yukari isn't too concerned because at least Tsukune and Moka are happy together.
    • After an initial bout of jealousy over Dark choosing Mizore over her, Felucia eventually gets over it as long as Dark is happy.
  • I Want Them Alive: In Act III, Kiria makes it clear that he wants Tsukune, Moka, and Kokoa captured alive, so he can infect them with Blackheart and use them in his plans. His attempt to do so on Ghoul!Tsukune in the final chapter of Act III results in his brutal dismemberment.
  • I Warned You: In Act III chapter 7, Dark, distrusting Tsukune to keep the ghoul sealed away even with the Holy Lock, explicitly warns him to stay away from Mizore or else Dark will kill him on the spot. In the next chapter, Tsukune approaches them, hoping to talk things over; unfortunately, Dark is done talking and promptly attacks him.
    Dark: I told you to stay away. But you just don't listen.
  • I Was Just Joking: In Act III chapter 6, Akua and Kahlua remark that, in order for Kokoa to truly regain her damaged pride, she will have to be a slave to Tsukune in every sense of the word, including sexually. Then they reveal it was just a joke; the gang is not amused.
  • I Will Only Slow You Down: In Act III chapter 8, when Tsukune and Dark are hanging off the cliff side, Dark tells Tsukune to just let him fall, pointing out that the rock Tsukune is holding onto is giving way and won't hold them both.
  • If I Wanted You Dead...:
    • In Act III chapter 12, while Dark is trying to stop the ghoul-infected Kokoa from tearing off Tsukune's damaged Holy Lock, Mizore points out that if Dark really wanted to kill either of them, he would have just snapped their necks already.
    • In Act IV chapter 1, when Tsukune recalls that he nearly died the last time he saw Moka's father, Inner Moka states that Issa always had a flair for dramatics and if Issa really wanted to kill Tsukune, he would have done so before Tsukune even crossed the threshold of the Shuzen estate.
  • If You Won't, I Will:
    • In Act III chapter 42, Hokuto tells Felucia that either she keeps Tsukune and Ruby from following him into the archives to steal the artifact he needs, or Jovian will. Considering the fact that Jovian just shot down Apoch in cold blood when she refused before, Felucia has little choice but to obey.
    • In Act VI chapter 17, after tensions between Mizore and Arial reach their boiling point and Dark sees Mizore beat Arial to near-death in a fit of rage, Moka insists that, even if Arial is sacred to Dark and it would crush him to discover the Awful Truth, Arial's obsession with Dark is out of control and she will tell Dark the truth about Arial if Mizore doesn't. Mizore reluctantly agrees to tell him.
  • Ignored Epiphany: For several chapters after Act VI chapter 18, Arial at first appears to realize that Dark doesn't love her and that she ruined his image of her, but the epiphany doesn't stick until after she plants a Forceful Kiss on him and causes him to Freak Out and get run over by a car in chapter 27.
  • I'm Standing Right Here: This exchange between Ageha and the bus driver in Act VI chapter 47:
  • Immortal Immaturity: Kahlua, despite being the second oldest of the Shuzen sisters, often acts childishly, throwing temper tantrums and watching children's cartoons. In Act IV chapter 4, when Kahlua is whining about having to use the bathroom, Kokoa lampshades her immaturity:
    Kokoa: How am I the younger sister here?
  • Immortal Life Is Cheap: As a doll demon, Felucia can survive and regenerate from literally anything so long as her spirit artifact is intact. Naturally, she tends to get the worst of the battle damage; among other things, she's been impaled, shot in the head, blown up, incinerated, and dismembered.
  • Immortality Hurts: Though she can survive and regenerate from anything as long as her Soul Jar is intact, Felucia can still feel the pain of her wounds and "dying" each time. By the time of Act IV chapter 6, the constant pain she's had to endure as a result of being constantly tortured and raped by Jovian and Jacqueline has actually started to drive her insane.
  • The Immune:
    • Discussed and averted in Act I chapter 23; Kurumu brushes off Yukari's warnings after she's dosed with the Love-Struck Potion, believing that, as a succubus, she is immune to love potions and charms. She promptly succumbs to the effects of the potion the minute she sets eyes on Rason.
    • Played straight in Act VI chapter 2, where it's revealed that, despite being a full-fledged vampire, Tsukune doesn't have a vulnerability to water and thus can come in contact with it without purifying the water with herbs.
  • Immune to Bullets: In Act III chapter 49, after being infected with Blackheart, Dark shrugs off a shotgun blast to the face.
  • Inept Mage: As shown in Act I chapter 12, Apoch and Astreal are not very good at mind control spells; their attempt to do so on Rason and Dark does nothing but put them in a trance, with the two barely responding to the sisters' commands at all. Later, in Act III chapter 13, their attempt to fix the damage done to the school only ends up causing even more damage.
  • Infant Immortality: Tragically averted in the case of Arial and Complica.
  • Inheritance Of Acquired Traits: Act VI chapter 45 reveals that Luna, Falla, and Complica all got their skills at drawing from their mother.
  • Insane Forgiveness: Tsukune is well-known amongst his friends as the forgiving type, but in Act IV, this is the others' reaction when he decides to forgive Akua and Kahlua for their actions, despite the fact that the two were working for Fairy Tale and were helping Kiria in an Evil Plan that would have destroyed the world. While even Moka and Kokoa, the two's sisters, are firmly convinced that Kahlua and Akua are beyond saving, Tsukune insists that they deserve a second chance because they did what they did in the belief that it would help their father and because they were nothing but Kiria's Unwitting Pawns all along.
  • Insane Troll Logic: In Act VI chapter 15, when the group is confronting Arial over her theft of Mizore's ring, Arial states that, since everyone keeps saying that she's Dark's guardian angel and essential mother, she has a say in who Dark marries and says that Mizore can't marry Dark. When Ruby points out that as Dark's mother, she can't marry Dark either, Arial promptly tells them to think of her as his stepmother with no blood relation, insisting that no matter what, she's the only one good enough for Dark.
  • Insistent Terminology:
    • Razico insists on being called a treasure hunter, not a thief.
    • In Act VI chapter 43, when Talon and co. realize that Ling Ling is undead:
    Rin: She's a zombie?
    Ling Ling: I prefer "jiangshi," but yes, zombie would be an accurate term for me.
  • Inspector Javert:
    • Talon Ryashen, having been turned into a Super Soldier by Fairy Tale, is determined to track down and kill any and all Fairy Tale operatives he can find. It doesn't matter to him if they were tricked, or if they're now heroes like Dark; if they were a part of Fairy Tale in any way, shape, or form, they're automatically evil and need to die.
    • As stated under Aggressive Categorism above, the HDA spends most of their appearances automatically deeming all monsters evil no matter what. Akasha lampshades this in Act VI chapter 25, pointing out that maybe monsters wouldn't be so inclined to attack humans if the HDA didn't constantly threaten them and accuse them of things they didn't do.
  • Instant Armor: Due to her infusion with Alucard's blood, Akua can manifest an organic chest plate for defense. The armor is durable enough that Akua was able to survive being shot by one of Jovian's energy beams.
  • Insult Backfire: In Act VI chapter 52, when Hex says that he won't help Complica unless the group plays his game and outright says that the lives of "lesser beings" like them are beneath his concern, this exchange happens:
    Kyouko: You're a monster!
    Hex: No, I'm not a monster. I'm more than that.
  • Interspecies Adoption/Raised by Natives: After the genocide of the chronoflies and her birth parents' death, Luna was adopted by a human couple; the two knew she wasn't human, but still loved her and were grateful to have a child.
  • Interspecies Romance: Several examples:
    • Rason Miyamosa and Kurumu Kurono, an angel and a succubus.
    • Dark Kuyumaya and Mizore Shirayuki, a shadow demon and a yuki-onna.
  • Interplay of Sex and Violence: In Act II chapter 32, while Moka, Mizore, and Kurumu are consummating their relationships with Tsukune, Dark, and Rason, respectively, Yukari and Kokoa are sparring outside.
  • Intimidation Demonstration: In Act I chapter 22, when Yukari unintentionally clocks Dark with a washtub, Dark proceeds to crush said washtub into a ball of metal and set it on Yukari's desk, telling her that, while he doesn't like to hurt kids, the next time she does something like that, he'll make an exception; Yukari faints on the spot.
  • Invincible Villain: Jovian and Jacqueline are set up to be this by all appearances and information in Acts III and IV. As Akua and Kahlua put it, their barriers are unbreakable, their energy blasts are unblockable, they never get tired, and their power levels are immeasurable. With the reveal that Apoch's Laser Blade can penetrate their barriers and deflect their energy attacks, they become Not So Invincible After All.
  • Irony:
    • In Act III chapters 23 and 24, Apoch and Astreal pick a fight with Yukari and try to kill her, insisting that she not take Ahakon away from them. Their attempts to stop Yukari from doing so end up being the very reason that Ahakon breaks up with them in favor of Yukari, as well as the fact that he got caught in the crossfire and would have been killed by the Ezranas if Luna hadn't intervened.
    • In Act VI chapter 20, it's revealed that Ran only fell in love with Ahakon because she was affected by a charming aura around her. The irony and embarrassment of a siren being the one charmed for a change is not lost on Ran.
  • It Can Think: During Acts II and III, this is a significant part of why the ghoul inside Tsukune is so dangerous; unlike a normal ghoul, it has its own personality and can think and plan.
  • "It" Is Dehumanizing:
    • Every time someone mentions Tsukune's inner ghoul in Acts II and III, they refer to him as an "it."
    • In Act V, Jenner Rythmore is so disdainful and distrustful of monsters that he calls them "things" on at least one occasion.
    • In Act VI chapter 49, while punishing Akua and Kahlua for not only failing to kill Talon, but letting him set foot in the Shuzen home, Issa outright refers to him as an "abomination" and an "it."
  • It Only Works Once: While the group is fighting Kuyou in Act III chapter 41, Mizore and Kurumu manage to land a blow on him with their duet. In chapter 42, when they try the attack again, Kuyou isn't about to let it happen twice and disrupts the attack by throwing Moka at them.
  • It's All About Me: First and foremost, Evil!Falla only cares about herself and acquiring power for herself. Even her own family comes second.
  • It's All My Fault:
    • In Act I chapter 4, Tsukune outright says that it's his fault Mizore picked a fight with Moka in her jealousy, remarking that he should have picked a member of his harem to be with a long time ago.
    • In Act III chapter 1, even as Tsukune tries to assure him that he doesn't blame her, Kokoa is adamant that his ghoul transformation is her fault because she was the one who botched the transfusion from the start, and because she was stupid enough to fall for the ghoul's trickery.
    • Zigzagged in Act VI chapter 44; upon discovering just how badly Kokoa had injured Sun, Gin wonders if he should actually blame Kokoa or blame himself for not clearing the air with Sun before things between Kokoa and Sun got so bad.
  • Jackass Genie: Pandora. As explained by Ceal in Act V chapter 29, he once wished for the dragon Fafnir to die "by his hand." Pandora granted the wish by severing Ceal's left hand, so he would only have the one hand to kill Fafnir with, and then making it so Fafnir can only be killed by Ceal.
  • Jerk with a Heart of Gold:
    • Arial leans pretty far into the "jerk" side of the spectrum in several parts of Act VI. She undeniably cares for Dark, but is insistent that Mizore is nowhere near good enough for Dark and has no qualms against informing Mizore as such in as much of a jerkish way as possible. Regardless, she's a fundamentally good person, and was one of the first monsters to be accepted into Heaven.
    • Ceal Erres is a bit of a jerk, and has to be outright begged to heal Dark when he's hit by a car, but regardless, he is a good person and in love with Falla, even if he can't bring himself to actually say it because of his upbringing, even becoming a big brother figure to Complica.
  • Jerk with a Heart of Jerk: The original Falla initially feigns trying to redeem herself and becoming friends with Kyouko and Tsukune's posse, all to dupe Luna into finishing the spell to give her her powers back.
  • Jerkass:
    • Jenner Rythmore, head of the Human Defense Agency. He doesn't even try to hide his open disdain and distrust for monsters, and outright states he's just waiting for an excuse to declare open war on them. While he is looking out for humanity, he could at least try to be less of a dick about it.
    • To describe the original Falla as a massive bitch would be an understatement. For example, she deliberately neglected to inform Complica that using the Chrono Displacement spell would kill her, and that's just for starters.
  • Jerkass Façade: In Act III, Dark states that he will kill Tsukune if he sees any sign that the Holy Lock's seal on the ghoul is weakening. When the chain starts to crack, Dark claims that he will eventually kill Tsukune, but it's revealed that he doesn't actually want to do so, with Dark coming up with excuses, such as Kokoa's debt to Tsukune, to keep him alive. Nonetheless, the act is successful enough that everyone believes it until Mizore and Felucia point it out to them.
    Rason: He could have told us that was his intention.
    Tsukune: He did it in his own way. He's Dark after all.
  • Jerkass Has a Point:
    • In Act III chapter 7, Dark actually does make a valid point when he expresses his doubts that Tsukune can't hold the ghoul off forever even with the Holy Lock, especially considering that the ghoul had previously influenced Tsukune's actions before without Tsukune knowing it.
    • When Yukari is in denial over her feelings for Ahakon in Act III and insists she belongs to Moka and Tsukune, Kokoa points out to her in a tactless way that no one ever objected to her dream to have a threesome with them because they knew she never stood a chance at doing so. Despite the way she says it, Yukari acknowledges she has a point.
  • Jerkass Realization:
    • In Act III chapter 44, the entire student body realizes just how poorly they've been treating Tsukune's posse at the sight of Yukari nearly killing herself to protect them from Fairy Tale; this realization galvanizes the students to help the gang fight the squadron off.
    • In Act VI chapter 47, Render criticizes a member of the HDA for trying to shoot and kill monster kids even if he was Just Following Orders. He promptly apologizes when the soldier reveals that, kids or not, the monsters responsible for the school attack killed his daughter.
  • Just Following Orders:
    • In Act I chapter 30, Rarosun and Surason invoke this when they reveal their Divide and Conquer plan, though it doesn't stop them from taking sadistic pleasure in watching Dark and Rason fight each other while mocking Kurumu and Mizore for falling for their trick.
    • Subverted in Act II; while Dark explains to Tsurara that he was just following orders when he and his original master attacked the Snow Woman Village years before, he knows it doesn't excuse his actions.
    • In Act V chapter 10, this is Rin, Ran, and Ren's explanation for why they charmed most of the male student body for Babylon. Even then, they are extremely conflicted.
    • In Act VI chapter 47, when Render is understandably uncomfortable with having to work alongside the HDA after they were nearly executed, the soldiers point out that they were following orders, just as they are now.
  • Kaleidoscope Eyes: Jovian's eyes are colored a mix of red, blue, green, and white, whereas Jacqueline's are colored a mix of yellow, pink, purple, and black.
  • Karmic Death:
    • In Act II, after raping Mizore and then taunting Dark about it, Miyabi gets his ass kicked and is literally torn limb from limb.
    • In Act III chapter 31, just as Kano is about to rape Mizore, he's killed by Luna, one of the girls he planned to rape as well.
    • After having personally murdered the original Apoch in Act III, Jovian is slain by Apoch's Alternate Timeline replacement in Act IV chapter 29.
  • Katanas Are Just Better: According to Mizore in Act VI chapter 15, a katana is Dark's favorite weapon.
  • Kent Brockman News:
    • In Act VI chapter 25, a male reporter shows up on the scene as Moka and co. are being held at gunpoint by the HDA, openly lambasting monsters and practically egging the soldiers on to execute them on the spot.
    • Akia Akiane, a reporter who has been seen reporting on monster attacks, has shades of this. In Act VI chapter 52, she starts going on about her Facebook and Twitter accounts and promoting her own autobiography before a fellow reporter calls her back to attention.
  • Kick the Dog:
    • In Act II, Miyabi extorts Mizore for sex in exchange for sparing Tsurara's life, and the minute he's finished, orders Tsurara's execution regardless while mocking Mizore's gullibility.
    • In Acts III and IV, Hokuto forces Felucia to aid him in his plans while letting Jovian and Jacqueline use her as their sexual plaything.
    • Also in Act III, the very first thing Kuyou does upon his arrival at Yokai is burn Astreal to death. During his fight with the gang, he even takes the time out to incinerate several non-combatants.
    • In Act III chapter 46, having found out that Hokuto has enslaved Felucia, Kiria takes the time to mock Dark over his failure to save her.
    • In Act IV chapter 23, Jovian taunts Tsukune over the phone about her sexual abuse of Kyouko.
    • A literal example in Act VI chapter 10; Ceal reveals that, while Fang Fang's dog was out, Ceal found him and fed him to Xarai, even tauntingly presenting him with said dog's collar. In a subversion, it's revealed that Fang Fang always hated the dog to the extent that he actually thanks Ceal and Xarai for doing so.
  • Kill It with Fire: Of a sort; Xarai can't actually be killed by fire, but it does cause him discomfort.
  • Kill It with Water: Played straight with vampires, but averted with witches. In Act VI chapter 42, while bathing with Ruby, Yukari, and the Ezrana sisters, Kyouko mentions that she thought water caused witches to melt, leading to this:
    Ruby: Yeah, I'm still lost as to how all those stories about us came to be.
    'Yukari: They got the part about vampires and water right. No idea where they're getting the rest of it from.
  • Kirk Summation: In Act IV chapter 24, Moka sums up Hokuto:
    Moka: You kidnap and brainwash our friend, you set Kuyou down upon us, you used us like toys... all so you can destroy the world with Alucard? All I see before me is a misguided fool that is going to be cast down into Hell.
  • Kissing Under the Influence: Upon being infected by part of the ghoul in Tsukune's body during Act III, Kokoa forces herself on Tsukune.
  • Knight Templar:
    • Talon Ryashen, the "Fairy Tale killer." He was turned into a Super Soldier by Fairy Tale, and is now on a Roaring Rampage of Revenge against anyone who was ever a part of the organization. It doesn't matter if said members defected, were Locked Out of the Loop, or non-combatants; if they were even remotely a part of Fairy Tale, they're on his hit list.
    • Fairy Tale themselves. For all of their claims on monster equality, they're more focused on anti-human extremism to the point that any monster who even thinks of siding with humanity is automatically the enemy; they have personally destroyed Ahakon's hometown for refusing to side with them, and tried to do the same to Mizore's hometown twice, on top of attempting to destroy Yokai Academy for teaching coexistence. In fact, in Act VI chapter 52, after seeing Moka preach human/monster coexistence on national television, both Gairen and Raika openly state that they're beginning to see why Gyokuro hates Moka so much.
  • Know When to Fold 'Em: In Act III chapter 9, after Kokoa, using her overcharge, has just jumped into water without ill effect to toss Kurumu out of the boys' bathtub, Mizore, not about to test her luck, quickly gets out of the tub and exits the building willingly.
  • Kung-Fu Sonic Boom:
    • To throw off her Superpower Meltdown in Act II, Kokoa attacks Tsukune's ghoul form with a Megaton Kick, the force of which blows apart the entire side of the house next to the group, turns the snow around them to steam, sends rocks and rubble flying, and knocks everybody flying.
    • In Act IV, a fully vampirized Tsukune's Finishing Move on Hokuto produces one that smashes a massive crater in the ground, causes a building to collapse, and completely obliterates Hokuto.
  • Lack of Empathy:
    • Jovian and Jacqueline display this masterfully, as shown in Jovian's merciless execution of Apoch in Act III chapter 41. Rason even outright states in Act IV chapter 24 that the two have no regard for the lives of others. In Act V, when Render and Leon call Jovian out for killing innocent humans in the school who had nothing to do with their fight, Jovian coldly responds, "You speak as if I care."
      • However, this only applies to the original Jovian and Jacqueline who worked for Hokuto; the re-summoned sisters in Act VI who serve Talon are considerably more sympathetic to others.
    • Having been the Kikions' original master, Hokuto is just as much disregard for life as they do. Throughout his screen time, he repeatedly blows off any and all pain and anguish he causes, insisting that it's all for a "higher cause." His idea of causing a distraction while he breaks into Yokai Academy's secured levels to steal an Artifact of Doom is setting Kuyou loose on the academy, and his idea of proving a point to Moka that human/monster coexistence is a fool's dream is by deliberately breaking The Masquerade and trying to get Tsukune and co. killed by humans while making Moka watch. On top of it all, he is an adamant nihilist who considers all forms of life, human or monster, to be meaningless trash.
    • Hex has little concern for the affairs of lesser beings. In Act VI chapter 52, when the group chews him out for not willingly helping Complica even though it's in his power to do so, with Fang Fang telling him in disgust that he can't seem to understand the value of life. Hex flippantly remarks that it's not that he doesn't understand the value of life; it's just that he couldn't care less.
    • Evil!Falla has a disregard for other people's lives that borders on sociopathic, openly comparing everyone around her to worms and ants and having done such things as send her own little sister Complica to her death For the Evulz. She even openly states that nothing matters to her more than power, not even her own family.
  • Ladykiller in Love: World-class Handsome Lech Gin ends up in a relationship with Kokoa as the fic goes on.
  • Lame Excuse: In Act VI chapter 27, Dark shows his Momma's Boy side by unsurely trying to justify Arial's Murder the Hypotenuse attempt on Mizore as just Arial being "a little overprotective." If by "a little overprotective" he means "literally clawing Mizore to pieces in a jealous rage," then yes, she was being overprotective.
  • Laser Blade: From Act IV onwards, Apoch can form two barriers, one of which takes on this form.
  • Laser-Guided Karma:
    • After spending much of Act III chapters 22 and 23 treating Yukari like dirt in their protectiveness of Ahakon and nearly killing her, Apoch and Astreal are beaten unconscious by Inner Moka. In the next chapter, when they try to Murder the Hypotenuse with Yukari and nearly hit Ahakon when he gets in the crossfire, Ahakon breaks up with them in favor of Yukari.
    • After sexually abusing Felucia and Kyouko, blowing up Tsukune's house, and causing all manner of trouble, Jovian and Jacqueline are dead by the end of Act IV. To put the icing on the cake, in Hell, Felucia, their former victim, is the one who tortures them... and she is very eager to pay them back.
    • After his death in Act III, Kuyou is shown in Act IV chapter 34 being tortured in Hell by Kenzo and his gang, whom Kuyou had killed during the events of Act III.
    • In Act VI chapter 52, during the baseball game, Arial yells "Swing!" while Mizore is up to bat, causing Mizore to reflexively swing and get two strikes. Arial is promptly warned not to do so again by Rason and Gabriel, but ends up getting hit in the head with the ball when Mizore hits it. Though Mizore insists it wasn't intentional, considering the fact that Arial had spent the entire fic belittling Mizore and treating her like scum, one could easily agree that karma caught up to her.
  • Last of His Kind: Luna and Falla are the only living chronoflies left.
  • Last Request: In Act VI chapter 52, as Complica is about to perish as a result of the Chrono Displacement spell's cost, she asks Arial to at least give Mizore a fair chance, as she and Dark are truly in love; Arial agrees, if only because Complica is her best friend.
  • Lawful Stupid:
    • Some vampire laws, such as the Eia Dreahl, come across as this. In Act III chapter 14, after a possessed Kokoa has her way with Tsukune, both Kokoa and Moka state that it doesn't matter whether or not Kokoa was in control of herself at the time; she still mated with Tsukune either way and broke the pact. If Dark hadn't exploited a loophole to get her off the hook, Kokoa would have been executed for something she had no control over.
    • In the first chapter of Act IV, the minute Issa finds out that Kokoa and Moka accidentally turned Tsukune into a ghoul, he starts physically attacking them along with Akua and Kahlua, furious that they didn't do their vampire duty and kill said ghoul on sight while all but openly dismissing the fact that they managed to cure him.
    • In Act IV chapter 16, Rason accuses the other angels as such, considering the fact that Hokuto is actively trying to resurrect Alucard and destroy the world, and they're not lifting a finger to stop him because, even if he is now a monster and regardless of how evil he is now, Hokuto was born human and thus, the angels' Thou Shalt Not Kill Muggles rule still applies to him until he actually dies with sin. Yes, that's right: the angels in Heaven are willing to let Hokuto revive an ancient Eldritch Abomination and wipe out all life on Earth because their laws insist that all humans, even ones as deranged and evil as Hokuto, are sacred and cannot be touched.
  • Leaning on the Fourth Wall:
    • Tsukune has made quips about how their lives have become like a manga or an anime at least twice. Both occasions result in a Popcultural Osmosis Failure on Dark's end.
    • While telling Mrs. Aono and Kyouko about everything that's been going on in Act IV, Kyouko remarks, "This is better than any fan fiction I've read online."
    • In Act V, after questioning why all of the new students end up in Ms. Nekonome's class, Rason remarks, "It's like a friggin' plot device or something."
  • Lesser of Two Evils: In Act VI, the group decides that they have a better chance at succeeding at getting a wish from Pandora's Box rather than playing Hex's game because, even if Pandora has a reputation as a Jackass Genie, they view defeating her pets as a better alternative to playing Hex's game and hoping to get lucky.
  • Lethal Chef:
    • In cooking class, Rason often sets his pots on fire. In Act II chapter 4, his attempt at making spaghetti and meatballs results in a giant green blob that actually appears to be moving.
    Kurumu: So... can I try it?
    Rason: I wouldn't if I were you.
    Yukari: I'm sorry. I must have used too much magic with my stew.
    Kurumu: How did you even make that from stew?!
    Luna: Your cooking's going to kill Ahakon if it doesn't kill us all first!
  • Literal Cliffhanger: In Act III chapter 8, Tsukune and Dark's brief fight leads to the cliff they were standing on giving way. Tsukune manages to catch hold of a rock and hold both himself and Dark up. Unfortunately, the rock can't support their combined weight and begins to give way, but Moka, Kokoa, Mizore, and Felucia work together to pull both boys up.
  • Literal Metaphor: In Act VI chapter 35, while explaining why they don't want Talon to free them from their servitude to him, Jovian and Jacqueline say that they'll die without him. Talon assumes that they're just being dramatic, until they explain that part of their summoning spell includes a curse that will eventually kill them unless they have a master to serve.
  • Locked Out of the Loop: When Dark was a part of Fairy Tale, he was kept in the dark about their anti-human agenda, discovering it when he learned they planned to destroy Yokai Academy for teaching the students to peacefully co-exist with humans.
  • Loophole Abuse:
    • In Act II, Kokoa, having fallen in love with Tsukune herself, invokes the Eia Dreahl, a sacred vampire pact that is punishable by death if broken, to see whether or not herself or Moka would be his mate. When they tell the others as such, they fail to specify that the pact was only supposed to be between the two of them, only stating that "the first girl to give Tsukune a nosebleed wins." Yukari promptly seizes this opportunity, with predictable results.
    • Likewise, Inner Moka also realizes that the pact didn't actually specify how Tsukune was supposed to get a nosebleed, only that he did get one, and thus wins by punching Tsukune in the face and giving him a bloody nose.
    • When Kokoa inadvertently breaks the Eia Dreahl by sleeping with Tsukune while possessed, Dark saves her from execution by pointing out that Inner Moka won the pact, but it was Outer Moka who actually mated with Tsukune. Since the two are a Split Personality and Inner Moka didn't actually break the pact, the agreement is null and void and thus no one has to die.
    • In the end of Act III, Tsukune uses the Chrono Displacement spell to rewind time by a day and save his friends from death, dooming himself to die by 10:45 PM the next day. When the time comes, however, Tsukune's ghoul form was in control of his body, and since it had its own identity and personality, the ghoul was killed instead, leaving Tsukune alive and cured of its influence.
    • In Act V, Babylon goes back on his word to set the Otonashi sisters free because they missed Razico when they charmed the student body, the deal being that they charm everyone who defeated Alucard. Of course, he then remarks that he probably wouldn't have let them go even if they had done so.
  • The Lost Lenore: Leon's late lover Selena, who was killed by a gang of rival treasure hunters after they retrieved the final key to Pandora's Box. Leon seeks to open the Box so Selena didn't die in vain.
  • Love at First Sight: Rason falls in love with Kurumu from the minute he sees her.
  • Love Before First Sight: As revealed in Act IV chapter 30, Felucia became infatuated with Dark before she even met him by reading over his file at Fairy Tale.
  • Love Hurts: Luna has had bad luck with boys. First, she's infatuated with Rason because he saved her, but Rason is with Kurumu and only loves her. Then, she falls in love with Hex after he saves her from Babylon's dungeon, only to once again suffer heartbreak when Hex admits that he only saved Luna for his own purposes and doesn't actually care about her. By the time of Act VI chapter 46, when she finds herself attracted to Gabriel, she's terrified of going along with it because she's afraid of getting her heart broken again.
  • Love Is a Weakness: Ceal came to believe that love and compassion are weaknesses after his little sister was fatally hit by a truck while trying to save a human child, remarking that his sister could have been a great doctor someday, but threw it all away because of her compassion for others.
  • Love Is in the Air: Act VI chapter 20 reveals that Ahakon is surrounded by a charming aura, which is in part why Ran and the original Ezrana twins fell for him.
  • Love Makes You Dumb:
    • In the latter chapters of Act II, Kokoa is so blinded by her newfound love for Tsukune that she doesn't realize that his inner ghoul is influencing his actions in order to manipulate her into finishing the transfusion and give him a power surge from her overcharge until it's too late. When she finds out, Kokoa is so devastated by her mistake and ashamed that she fell for the ghoul's trickery that she nearly commits suicide.
    • In Acts V and VI, Arial takes it Up to Eleven, adamantly refusing to accept that Dark doesn't love her as a wife until after she causes him to have a massive Freak Out that nearly leads to his death.
  • Love Potion: In Act I chapter 23, Yukari creates a love-struck potion to help Tsukune and Moka in their relationship, but it backfires when Moka, Kurumu, and Mizore use it all at once and nearly force themselves on their respective beaus right then and there. Act IV chapter 17 reveals that Ruby kept the potion for some reason; Falla, Apoch, and Astreal mistake it for perfume and use it, and Hilarity Ensues when Moka, Luna, Yukari, and Kokoa end up dosed with it as well.
  • Loves the Sound of Screaming:
    • In Act II chapter 22, after raping Mizore, Miyabi is openly disappointed that Mizore didn't scream even once.
    • In Act V chapter 36, with Kyouko at her mercy, the dark Falla urges her to scream and beg for her life before she dies.
  • Luke, I Am Your Father: Act II reveals that Kurumu's father is none other than the Lord of Hell himself, having conceived her with Ageha during a one-night stand; Kurumu herself is unaware of her father's identity until she meets him personally in Act V chapter 8.
  • MacGuffin Girl: Luna, Falla, and Sun are this to Babylon in Act VI; he plans to use Luna and Falla to breed more chronoflies for his army, and to use Sun for her siren powers to enslave powerful monsters, as Sun, unlike most other sirens, can charm both male and female monsters.
  • Made a Slave: Ran, Rin, and Ren were kidnapped and enslaved by Babylon's army when they were children, and forced to charm monsters for them.
  • Made of Evil: Shadow demons such as Dark are stated to be beings of pure evil formed from Hell itself.
  • Made of Iron: Dark is able to keep standing and fighting after, among other things, getting impaled with Sinister Scythes and getting drained of blood by a crazed Tsukune. It's outright stated that he has a high pain tolerance.
  • Magnetic Hero:
    • When Dark defected from Fairy Tale, several other members followed his example.
    • In Act III chapter 44, after seeing Yukari's near-Heroic Sacrifice to protect them, the entire student body is inspired to jump into the fray and help the gang fight off Fairy Tale.
  • Make an Example of Them: In Act II, when Fairy Tale is occupying the Snow Women Village, Miyabi decides to have Mizore's mother Tsurara executed to teach the other snow people their "place." It also doubles as a big Kick the Dog moment because mere moments before giving the order, he'd extorted Mizore for sex in exchange for not doing so. Fortunately, Tsukune and the others put a stop to it.
  • Making Love in All the Wrong Places: While Tsukune & Moka and Dark & Mizore all have the decency to retire to other rooms to make love, Rason and Kurumu just elect to do it right in the middle of the Shirayuki family's living room, all over the place and in various positions.
  • Manchurian Agent: As revealed in Act VI, Falla had Rin's headphones rigged to drive her into a berserker rage whenever she hears heavy metal music. Both times it has happened, Rin ended up destroying her hometown and Yokai Academy.
  • Manipulative Bastard:
    • In Act II, the ghoul inside Tsukune exploits Kokoa's newfound feelings for Tsukune to dupe her into finishing the blood transfusion while activating her overcharge, which allows him to become a full-fledged ghoul and usurp Tsukune's body completely.
    • Throughout Act III, Hokuto plays the entire group to steal the Artifact of Doom he needs for his plan.
    • In Act IV, the original Falla faked wanting to reform and befriending Kyouko to dupe Luna into finishing the spell to restore her chrono magic. As soon as the plan succeeds, Falla drops the act and kills Luna on the spot while gloating about how easily the gang fell for it.
  • Meaningful Name:
    • Dark's name; he took his last name from Arial Kuyumaya, the little snow girl who he was forced to kill and who granted him freedom with her last breath, while his first name was from Arial remarking that even if he was dark, she didn't hate him.
    • As revealed in Act VI, Sun took on the surname Otonashi in honor of Rin, Ran, and Ren's family, having been unaware that the sisters survived the destruction of their hometown.
  • Megaton Punch: After Sun's jealousy of her relationship with Gin pushes her too far in Act VI chapter 42, Kokoa nails her with one that sends her clean through a wall. It's later revealed in chapter 44 that Kokoa's punch had completely pulverized Sun's eyeballs and cracked her skull, and if Kokoa had put just a little more power into the attack, she would have shattered Sun's head completely.
  • Mercy Kill: In Act VI chapter 2, Gabriel shoots an HDA soldier in the head to spare him a more agonizing death at Ceal's hands.
  • Mind-Control Eyes:
    • In Act III chapter 12, while being controlled by the ghoul's essence, Kokoa's sclerae develop spiderweb-like patterns.
    • In Act IV, after being charmed by Jovian and Jacqueline, Felucia's eyes are described as having a yellowish tint.
  • The Millstone: Act VI has one in the form of Arial Kuyumaya. While she does help Moka and the gang escape from captivity in the HDA, due to her stubborn obsession with Dark, as well as the yandere tendencies that come with said obsession, the group openly state on more than one occasion that Arial has caused nothing but trouble since she met up with them.
  • Mismatched Eyes: Hex has one red eye and one purple eye, while Pandora has one blue eye and one yellow eye.
  • Mistreatment-Induced Betrayal: The entire reason Apoch and Astreal fled from Ghaldin in the first place was because they got fed up with being abused and used to kill people. Similarly, the Clone Army of the sisters that Fairy Tale summoned during Act II ultimately turned on Fairy Tale and killed them when they got sick of the abuse.
  • Mix-and-Match Critters:
    • Kirlings, described as a cross between dogs and lizards.
    • Chrono wraiths are described as looking like manta rays with spider legs.
  • Moment Killer: Averted. In Act I chapter 5, when Tsukune is about to announce to his Unwanted Harem which one of them he wants to be with, Gin barges in at that moment and interrupts; the girls promptly toss him out a window and urge Tsukune to continue.
  • Momma's Boy: Dark has become one to Arial as of Act VI, being literally unable to go against her even though she is trying to control his love life.
  • Money to Burn: In Act VI chapter 11, Ceal makes Fang Fang pay him 9000 gold bars to repay a debt, and promptly feeds the gold to Xarai, admitting that wealth is no problem for him and he wanted the gold just so he could take it away from the Huangs.
  • Monster Protection Racket: Invokved; in Acts V and VI, several HDA operatives believe that Tsukune and co. deliberately set Alucard loose just so they could kill him and make themselves look like heroes, which couldn't be any farther from the truth.
  • Moral Myopia:
    • In Act III chapter 24, when Apoch and Astreal regain consciousness after getting beaten up by Inner Moka, they're instantly terrified at the sight of her and scream about how she's going to kill them. As Inner Moka points out, they have little room to talk since they almost killed Yukari beforehand.
    • The original Jovian and Jacqueline who served as Hokuto's Co-Dragons absolutely thrive on pain, violence, and mass destruction... as long as they're the aggressors, not the victims. Case in point: in Act IV, Jovian had previously killed the original Apoch in cold blood during Act III and spent several chapters of Act IV going on a massively destructive rampage through Tsukune's hometown alongside Jacqueline For the Evulz, but in Act IV chapter 28, the minute Apoch and Astreal successfully kill Jacqueline, Jovian completely drops all pretense of playfulness and starts spamming Wave Motion Guns at the Ezranas in an Unstoppable Rage.
    • After accepting her role as Dark's guardian angel/mother figure in Act VI, Arial insists that Mizore isn't good enough for Dark in part because Mizore doesn't respect her; considering the fact that Arial had previously nearly murdered Mizore in a jealous rage, stole her engagement ring right off of her hand, and is continuing to be a complete Jerkass to Mizore despite all of her attempts to reason with her and win her approval, Arial has literally done absolutely nothing to deserve any respect from Mizore.
  • Motor Mouth:
    • Complica has been noted to talk non-stop and forget to breathe until she passes out.
    • According to Dark, the only way he's ever been able to get Felucia to shut up is by blowing her head off.
  • Murder the Hypotenuse:
    • Mizore of all people attacks Moka and tries to do this to her in a rage in Act I; Tsukune's Taking the Bullet for Moka snaps her out of it.
    • In Act III, Apoch and Astreal become insanely protective of Ahakon and nearly kill Yukari to keep her from stealing him. Ironically, this attempt is exactly what causes Ahakon to dump them in favor of Yukari.
    • In Act IV, Falla attempts to kill Moka by setting up various Death Traps in the girls' dormitory in order to Make It Look Like an Accident. She fails miserably, and after briefly reverting to her old evil self thanks to Lilith's Mirror, she finally accepts that Tsukune is Moka's boyfriend and not hers.
    • In Act VI, Arial tries to do this to Mizore upon finding out she's Dark's girlfriend, and it's only thanks to Ceal that Mizore survives.
  • My Beloved Smother: After getting over her Yandere phase in Act VI chapter 27, Arial becomes this to Dark, insisting that it's up to her who Dark marries. Both Kurumu and Rason state that perhaps things were better when Arial was obsessed with Dark.
  • My God, What Have I Done?: Several examples:
    • When Tsukune takes the bullet for Moka during her fight with Mizore in Act I chapter 4, Mizore is instantly horrified at what she's done to the extent that she's perfectly willing to let Inner Moka kill her.
    • After that, when Tsukune explained that he had been waiting so long to pick a member of his Unwanted Harem to be with because he didn't want to ruin his friendship with the other three, the girls have this reaction for putting him in such a position.
    • In Act I chapter 30, after the Kiyo brothers reveal their Divide and Conquer plan, Kurumu and Mizore are completely ashamed of themselves for having played right into their hands, especially since they never once suspected foul play and were so ready to believe the worst in Rason and Dark.
    • Act II is more along the lines of My God, What Did I Almost Do?, but the basic principle is the same. In Act II, Kokoa challenges Moka for the right to be Tsukune's mate via the Eia Dreahl, a vampire pact that is punishable by death if broken, firmly believing that Tsukune isn't safe with Moka because she keeps putting him in danger. She ends up losing said pact, and it's only afterwards that she realizes that Moka never put Tsukune in danger, and he was fighting of his own choice and loves Moka regardless; realizing what she would have taken away from Tsukune if she had indeed won the pact, Kokoa is instantly ashamed of herself.
    • In the first chapter of Act III, this is Kokoa's exact reaction when she realizes that the ghoul was manipulating Tsukune from within to trick her into giving it enough power to take over Tsukune's body; she's so devastated that she nearly kills herself.
    • In Act III chapter 24, Apoch and Astreal react as such when it appears they've killed Ahakon while fighting Yukari over him.
    • In Act IV chapter 13, this is Falla's reaction when her emotional outbursts over the fact that the Tsukune of the main timeline loves Moka and not her causes herself and Moka to fall through time, leading to Moka being near-fatally poisoned by a pack of kirlings.
    • In Act IV chapter 17, this is Mizore's near-word-for-word reaction when she realizes that Dark just saw her beat Arial to a bloody pulp.
    • In Act VI chapter 27, Arial has such a moment when she finally realizes that her role was as Dark's guardian angel, not his soul mate, and by confessing to him, she has essentially deprived him of his reason for living.
    • In Act VI chapter 44, Kokoa has another moment when she discovers that her attack on Sun has essentially left the latter brain dead.
  • My Species Doth Protest Too Much/Token Heroic Orc: Dark's race, the shadow demons, are explicitly stated to only exist to kill at the behest of their summoners. Dark, however, is the exception.
    Dark: So what if I was born from hatred and fear? I never wanted to be evil. I never wanted to be a killer.
  • Neighbourhood Friendly Gangsters: The Huang family, as depicted in Act VI. They're part of the Chinese mafia, but have been shown to be quite a friendly bunch; Felucia admits that she trusts Fang Fang completely. Also, Ten-Ten saved Akua and Kahlua from Talon even though she didn't have to. Fang Fang even tells the group that, while they are a mob family, all of their dealings are legit.
  • Neural Implanting: In Act VI chapter 40, Hex implants full knowledge of himself, Pandora, Babylon, and Babylon's army into the minds of the dark lords after they win his game. In Act VI chapter 50, he does the same to Moka's group and the HDA when Akasha wins his game.
  • Never My Fault:
    • In Act I chapter 21, a bully in the kendo club deliberately bumps into Yukari and then has the gall to tell her to watch where she's going.
    • In Act VI chapter 27, Arial insists that Mizore is not good enough for Dark in part because Mizore doesn't respect her. As pointed out by the others, Mizore has good reason not to respect her because Arial nearly killed Mizore in a jealous rage less than twenty-four hours ago.
  • Nice Job Breaking It, Hero:
    • During the climax of Act II, Kokoa is duped by the ghoul in Tsukune's body into giving it enough power to take over Tsukune. When she discovers the ghoul's deceit, Kokoa is so ashamed of having fallen for it, and horrified at what she has done to Tsukune, that after an Interrupted Suicide, she swears fealty to Tsukune in atonement.
    • In the early part of Act III, Ahakon accidentally leads Fairy Tale back to Mizore's hometown while running from them. To be fair, though, he had no idea that the Snow Woman Village was nearby.
    • In Act III chapters 14 and 15, Apoch and Astreal misread the instructions while making Yukari's new wand and make it with a Zeta-line seal instead of a Beta-line one, causing the wand to drive Yukari insane with power and resulting in Tsukune cracking two more links in his Holy Lock to stop Yukari.
    • In Act III, after one fight in school too many, the headmaster tells Tsukune and co. that they will be separated if another incident happens. Unfortunately, Kano uses this to his advantage to blackmail the girls into letting him take pin-up photos of them, knowing that if they retaliate, they'll only dig themselves in deeper with the headmaster. After Kano is dealt with, the headmaster changes his mind and allows the gang to exercise their right to defend themselves if any other student tries to harass them.
    • As revealed in the final chapter in Act III, Tsukune and co.'s defeat of Kiria allowed Hokuto to carry on with his plan to resurrect Alucard, as Hokuto promised Kiria that he wouldn't enact said plan unless Kiria's own plan failed.
    • In Act V, the angels recruit Luna to examine a mysterious rift in Heaven, believing it to be a rift in the time stream that Luna could repair. Unfortunately, said rift was actually a portal into Babylon's world, and Luna is promptly captured and imprisoned to be used as a breeder for his army.
    • In Act VI chapter 37, Complica tries on Luna's stabilizing bracelet, but her chrono magic overloads said bracelet to the point that it explodes and tears open a rift to Babylon's world. Babylon wastes no time in personally showing up with an armada, capturing Luna, Falla, and Sun, and killing everyone else except for Complica, Kou, and Xarai. If Complica hadn't cast Chrono Displacement after the massacre, Babylon would have won right then and there.
    • In Act VI chapter 51, when Akasha decides to play Hex's game to create a gateway to Heaven for Complica, Falla interferes with her attempt while insisting that, as Complica's sister, she should be the one to do it; Akasha gets a bad roll and loses her heart to Hex as a result, with Hex even flat-out remarking that Akasha probably would have won if Falla hadn't screwed it up.
  • Nice Job Fixing It, Villain:
    • In Act I chapter 30, Rarosun and Surason have Dark and Rason tricked into thinking that they molested the other's respective girlfriends, and have Mizore and Kurumu restrained and are making them watch the fight. However, the two get tired of waiting and decide to morph into Mizore and Kurumu and give the boys the final push to kill each other; instead, Dark and Rason see through their disguises, promptly kill the Kiyo brothers, and subsequently realize they were duped. In short, Rarosun and Surason screwed themselves over through their own impatience and sadism.
    • In Act IV chapter 19, when Hitomi petrifies Moka, it allows Inner Moka to bypass her seal, break free of the petrifaction, and kick her ass.
  • No Accounting for Taste: This is the entire group's reaction to Kokoa's decision to date Gin in Act III chapter 35. Kurumu even flat-out asks Kokoa if she's that desperate for a boyfriend.
  • No, Except Yes: In Act III chapter 41, Hokuto takes the time to watch the carnage Kuyou is inflicting on the academy. When Felucia asks him if that's how he gets his kicks, Hokuto responds:
    Hokuto: Hardly, but I'm not against enjoying the moment.
  • No Good Deed Goes Unpunished: In his backstory, Rason saved a monster girl (later revealed in Act III to be Luna) from a human rapist, and the other angels responded by banishing him from Heaven because angel laws explicitly state that humans are sacred and must be protected no matter what until they actually die with sin. And that's only because one of the elders opted for leniency and decided to give Rason a chance to prove that monsters can be both good and evil just like humans; the other angels originally planned to just execute him.
  • No Ontological Inertia:
    • In Act IV chapter 18, upon Hitomi's death, all of those she petrified return to normal.
    • Similarly, both times Jovian and Jacqueline are killed, the mind control spell they cast on Felucia, and later Apoch and Astreal, are automatically broken.
  • No Sell:
    • Being essentially made of fear itself, Dark is immune to Luna and Falla's ability to produce fear-inducing dust, as well as necro magic.
    • Similarly, in Act IV, the pack of Kirlings is immune to Falla's fear dust because they're nothing but mindless beasts who can't feel fear.
  • Non-Indicative Name: Paradise, the Pocket Dimension Tsukune is quarantined in for most of Acts V and VI in order to get his vampire instincts and bloodlust under control. It's actually filled with numerous demons and monsters to be used for study and research. Ahakon even lampshades the name.
  • Not Helping Your Case:
    • Just about every time someone tries to lecture her about her Hair-Trigger Temper, Arial ends up blowing her stack.
    • In the first few chapters of Act VI, while escaping from the HDA compound, Moka and co. are forced to fight back against the soldiers, even killing some of them; the group even acknowledges that it doesn't help their claims of peace, even if they had no choice but to fight back.
    • In Act VI chapter 44, after it's revealed just how badly Kokoa injured Sun, Kokoa insists that she never meant for it to happen, whereas Felucia points out that Kokoa's actions beforehand speak differently:
    Kokoa: I'm sorry, Gin. I didn't mean to hurt her so badly.
    Felucia: You were chasing me in the halls to slaughter her in your rage. To an observer, it would seem like you were trying to kill her.
    • In Act VI chapter 47, when Tsurara tells Ageha that she looks like "a whore off the street," it leads to this exchange:
    Ageha: How dare you group me with those inexperienced and trashy sluts that claim they know how to satisfy a man. I'll have you know that I've slept with greater and more powerful men than you ever will!
    Tsurara: And that defends you against my statement of you being a whore how?
  • Not Now, Kiddo: In Act IV chapter 24, Astreal reveals that Apoch's Laser Blade is able to penetrate Jovian and Jacqueline's supposedly unbreakable barriers. When asked why they didn't tell them earlier, Astreal points out that they tried to, but the others insisted that they could handle it and explicitly told the Ezranas not to bring it up again.
  • Not So Invincible After All:
    • In Act III, Tsukune's Holy Lock is stated to be indestructible, which is proven wrong when it's revealed that every time Tsukune uses his full power, the lock cracks. In chapter 15, when Felucia remarks on the "piss poor job" the Holy Lock is doing on not breaking, Rason confesses that the lock was never actually made in mind to keep a ghoul sealed away, especially not one as powerful as Tsukune's, and that it's a miracle the lock has managed to repress the ghoul at all.
    • During Acts III and IV, it's repeatedly stated that Jovian and Jacqueline are unstoppable. Naturally, the two are taken aback when Apoch manages to penetrate their supposedly unbreakable barriers.
  • Not What I Signed On For: In Act III, Akua and Kahlua joined up with Fairy Tale and help Kiria in his plan with the intent to make Issa one of the top dark lords once humanity is subjugated. They have this reaction when they discover in chapter 52 that Kiria didn't just plan on using the Chrono Displacement spell to send Ghoul!Tsukune back to the Battle of Kahdaln and rewrite history in favor of the monsters: he also planned on using it to send Blackheart-enhanced monsters out to wipe out the dark lords and all of the other powerful beings of their time, thus ensuring that Kiria would be the top monster in the new timeline, and that he would have infected Akua and Kahlua with Blackheart and sent them back to kill their father as part of it.
  • Not What It Looks Like: In Act III chapter 35, Tsukune and co. walk in on Kokoa and Gin getting intimate in the newsroom, upon which they immediately assume that Gin was forcing himself on Kokoa and viciously attack him before Kokoa explains the situation.
  • Not Worth Killing:
    • In Act I chapter 16, Dark comes within a hair's breadth of snapping Kotsubo's neck upon hearing that he tried to molest Mizore last year, but Tsukune and Rason persuade him that it's not worth it. Nonetheless, Dark makes it clear that he will kill Kotsubo if he so much as looks at Mizore again.
    • In Act VI chapter 38, after killing everyone else at the villa, Babylon tells Kyouko that he knew she was hiding from him all along, but lets her go because killing a simple human like her isn't worth his time; Kyouko ends up dying regardless after Taking the Bullet for Complica from a rylo.
  • The Nothing After Death: Up until the end of Act IV, this was the fate of any deceased monsters, whereas demons such as Kurumu or Dark would be sent to Hell by default. Thanks to Rason's efforts, benevolent monsters are now being allowed into Heaven as well.
  • One-Man Army:
    • In Act II chapter 22, Dark makes his entrance at the Snow Woman Village by dismantling an entire Fairy Tale squadron all by himself.
    • In Act III chapter 10, in order to make sure that Tsukune can stay in full control with the Holy Lock, the headmaster arranges for him to fight Dark, Rason, Gin, Ahakon, Apoch, and Astreal all at once; as soon as Tsukune cuts loose, he makes short work of all of them.
  • One-Winged Angel: In Act IV chapter 30, Hokuto decides to fight Tsukune for real and thus tears off his Holy Lock. He proceeds to dominate Tsukune and fatally impale him, but the Shuzen sisters all use their blood to revive him as a full-fledged vampire, after which Tsukune completely curb-stomps him.
  • Only I Can Kill Him: As a direct result of Pandora's Jackass Genie tendencies, Fafnir has Complete Immortality unless Ceal kills the dragon himself.
  • Only in It for the Money: Averted; in Act V chapter 29, Ceal makes it clear that he has no interest in the treasure trove that Fafnir guards; he just wants to slay the dragon because it's his Family Business, and to avenge the family members who were killed by Fafnir.
  • Only One Name: Hex uses the surname Lagon while in the monster world, but in truth, he is this trope.
  • Original Character: Rason, Dark... the list goes on.
  • Out-Gambitted: In Act IV, after learning that Hokuto is apparently planning a full-on attack on Yokai Academy to capture Moka in the future, Tsukune and co. take time to prepare. However, they fail to consider the fact that Luna and Falla, two Time Masters, weren't present during the attack in that timeline, and are caught unprepared when Hokuto does factor in Luna and Falla's presence and instead has Jovian and Jacqueline kidnap Kyouko and Tsukune's mother and hold them hostage at opposite sides of Tsukune's hometown in order to Divide and Conquer the group while a Brainwashed and Crazy Felucia forces Moka to go with her to Hokuto without a fight in exchange for the lives of Tsukune's family.
  • Pædo Hunt:
    • In Act II chapter 37, one member of Kenzo's gang repeatedly eyes Yukari to the extent that Dark explicitly threatens to kill him if he doesn't stop.
    • In Act III chapter 31, Kano blackmails Yukari and forces her to participate in his pin-up photo shoots with the rest of the girls, much to their disgust.
  • Person of Mass Destruction: During the climax of Act IV, Jovian and Jacqueline reduce a significant portion of Tsukune's hometown to rubble.
  • Pet the Dog: While revenge-driven to the point of entering He Who Fights Monsters territory, Talon does have some humanity left. In Act VI, he personally stops Saizo from feeling up Kyouko, and later helps Rin by having Jovian and Jacqueline break the spell Rin had over her memories.
  • Pitiful Worms:
    • Hex, Pandora, and Babylon can barely form a sentence without derisively calling humans and monsters "lesser beings."
    • The dark Falla likes to refer to humans and other monsters as ants.
    • In Act V chapter 36, during the school attack, Jacqueline outright refers to the humans as "filthy bugs."
  • Playboy Bunny: In Act I chapter 33, Ruby shows up to the school dance dressed as one.
  • Please Kill Me If It Satisfies You:
    • In Act I, upon Ghaldin's death, Astreal offers up her own life to Tsukune and the others in penance for brainwashing Dark and Rason, while begging them not to hurt Apoch. They opt to give them both another chance.
    • When he meets Mizore's mother Tsurara in Act II, Dark promptly offers his life to her in penance for the snow women he killed under orders years before. After a moment, Tsurara decides to let him live.
    • In Act VI, after dishing out a "The Reason You Suck" Speech to a crowd of humans, including HDA soldiers and police officers, Moka gives the HDA free rein to gun her down if there really is no chance of peace between monsters and humans, but to remember that they're willing to give peace a chance, and that Babylon will not show such mercy when he makes his move. Instead, the director of the HDA orders his troops to stand down and agrees to speak with Moka and Akasha.
  • Pocket Protector: As revealed in Act V chapter 29, Leon survived being shot by a rival treasure hunter because a locket he was wearing took the bullet.
  • Poor Communication Kills:
    • In Act II chapter 29, after explaining the rules of the Eia Dreahl to the rest of the group, Kokoa specifies that the first girl to give Tsukune a nosebleed wins and that the loser would have to forfeit Tsukune to the winner forever under penalty of death, but not that the pact was only meant to be between herself and Moka; thus, any girl who gives Tsukune a nosebleed can claim him for her own, an opportunity that Yukari is quick to seize.
    • In Act IV chapter 20, Astreal informs the boys that Kokoa "wants" them, failing to specify that she wanted them to watch how far she could push her overcharge; the boys end up thinking she wanted the entire group to have an orgy, with Gin actually stripping down on the spot.
  • Popcultural Osmosis Failure: On two different occasions, a member of Tsukune's posse remarks on how their lives are becoming like a manga or an anime, to which Dark asks what a manga/anime is. Both times, the others just give him confused stares before letting the matter drop.
  • Post Rape Taunt:
    • Act II uses this spectacularly. Miyabi rapes Mizore, and when Tsukune and the others find out, he taunts Dark by remarking, "If it makes you any feel better, she wasn't that good. She didn't even scream for me." He gets his just desserts soon after.
    • In Act III chapter 12, the possessed Kokoa takes it a step farther after her rape of Tsukune by rubbing her crotch, licking the vaginal blood off of her hand right in front of Moka, and declaring it "delicious," at which point Moka snaps and dishes out a No-Holds-Barred Beatdown.
    • In Act IV chapter 23, after having spent the entire night holding Kyouko hostage and raping her, Jovian proves just what a monster she is by calling Tsukune over the phone and boasting about how Kyouko "tastes so good."
  • Pragmatic Villainy:
    • In Act II, this is the only reason Tsukune's inner ghoul helps save Kokoa from a Superpower Meltdown; so it could use Kokoa's newfound feelings for Tsukune to its advantage by manipulating her into giving it enough power from her overcharge to hijack Tsukune's body completely. The others are Properly Paranoid enough to suspect that the ghoul had an ulterior motive, but, unfortunately, fail to realize just what until it's too late.
    • In Act III, Falla helps Luna figure out how to save Rason by freeing her from her prison and avert Luna's Suicidal Cosmic Temper Tantrum. Not because she actually cares if Luna destroys the world, but because Luna is The Only One who can free her.
  • Properly Paranoid: In Act III chapter 36, the gang is unsurprisingly wary of Jovian, who looks just like Apoch, since Fairy Tale had previously used Apoch and Astreal's spell to create a Clone Army of the sisters. By chapter 41, it turns out that Jovian really is just another Apoch duplicate, albeit an enhanced one.
  • Psycho Serum: Blackheart, a formula created by Fairy Tale which greatly enhances a monster's strength, but drives them into a berserk frenzy that lasts until the serum kills them an hour later. As of Act VI chapter 49, it's revealed that Fairy Tale has improved the serum to eliminate the drawbacks, thus making it a generic Super Serum.
  • Psychopathic Manchild: The original Jovian and Jacqueline Kikion who served Hokuto are a Type C. They're both incredibly powerful and nearly unstoppable... and they're also completely Ax-Crazy Psycho Lesbians whose idea of "playing" involves such things as Cold-Blooded Torture, rape, and overall committing wanton mass murder; to them, life is a game, and killing people is their favorite pastime. To drive the point home, in Act III chapter 42, Jovian even cheers "Yay, I love killing!" in a manner reminiscent of a five-year-old with a cool new toy, and in Act IV chapter 25, when Gin saves Mrs. Aono's life after Jacqueline blows up Tsukune's house just to torment Tsukune, Jacqueline whines that Mrs. Aono should have died in the explosion and that Gin "didn't play fair." Hell, even before The Reveal in Act III that Hokuto and Jovian were Evil All Along, they had shades of this; in Act III chapter 36, after the group accuses her of being one of the witch sister duplicates that Fairy Tale created using Apoch and Astreal's spell (which is technically true), Jovian blatantly refuses to repair Tsukune's Holy Lock, even after they apologize, and forces Astreal to kiss her in exchange for doing so. Considering that their (lack of) morality was in part influenced by Hokuto's, they're also living proof of just how far gone Hokuto is.
  • Pummeling the Corpse:
    • Upon being freed from Ghaldin's mind control after Moka kills him in Act I, Dark is so furious over being controlled that he promptly makes his way over to Ghaldin's corpse and literally stomps his skull into a bloody stain.
    • In Act III, it's mentioned that Tsukune and the other boys take their rage out on Kano's body after discovering that he had been blackmailing the girls into letting him take dirty pictures of them, and had even planned to rape them before Luna killed him; by the time they're through, there's nothing left of Kano but ashes.
  • Punch Catch:
    • In Act III chapter 12, Tsukune pulls one off against the possessed Kokoa; however, Kokoa uses this to her advantage to try to tear off the Holy Lock with her free hand.
    • In Act III chapter 42, Tsukune pulls another one off against Kuyou, who has just enough time to make an Oh, Crap face before Tsukune starts beating the piss out of him.
  • Punctuated! For! Emphasis!:
    • In Act IV, when Moka asks Hokuto if he knows what exactly will happen if he awakens Alucard, Hokuto responds:
    Hokuto: Yes, he'll destroy everything. Every. Last. Living. Soul.
    • In Act VI chapter 20, Moka does this to Arial after getting sick of her obsession with Dark:
    Moka: Get it through your head, Arial. Open your eyes and see what's in front of you for once. Dark. Loves. Mizore!
  • Punctuated Pounding:
    • Kyouko gets a moment while beating on Evil!Falla in Act V chapter 37:
    Kyouko: YOU! DAMN! MONSTER!
    • In Act VI chapter 17, Mizore does this while whaling on Arial:
    Mizore: Know! Your! Place!
  • Punny Name: All named members of Luna's family; Ultima Cii (ultimacy), Lega Cii (legacy), Luna Cii (lunacy), Falla Cii (fallacy), and Complica Cii (complicacy). Rason also points out that Moka and her sisters are all named after beverages. Neither Moka nor Luna get it.
  • Put the "Laughter" in "Slaughter":
    • In Act III chapter 52, Ghoul!Tsukune laughs as he disembowels Kiria with his bare hands.
    • During the climax in Act IV, Jovian and Jacqueline absolutely thrive on the destruction and death they cause as they reduce a great deal of Tsukune's hometown to rubble.
  • Rage Breaking Point:
    • In Act III chapter 42, after the deaths of Apoch and Astreal, as well as The Reveal that Hokuto and Jovian were Evil All Along and that they enslaved Felucia and orchestrated Kuyou's attack on Yokai Academy, Tsukune hits it big-time and proceeds to blow Kuyou away in an Unstoppable Rage.
    • In Act V chapter 37, Kyouko, having gotten sick of being a Distressed Damsel and being used against her loved ones and friends, snaps and physically assaults Evil!Falla.
    • In Act VI chapter 20, Moka hits hers when she finally gets sick of Arial, Ran, and Sun being Clingy Jealous Girls over Dark, Ahakon, and Gin, respectively, and gives all three of them a serious tongue-lashing.
  • Rape Is a Special Kind of Evil:
    • Miyabi rapes Mizore in Act II while holding her captive, and is brutally killed by an outraged Dark soon after.
    • Similarly, among the other things that the numerous duplicates of Apoch and Astreal are used for is as Sex Slaves for Fairy Tale soldiers.
    • In Act III chapter 12, Kokoa's ghoul-induced Split Personality rapes Tsukune, going so far as to paralyze him with a "love tap" to the spine to ensure he would hold still while she did so.
    • Jovian and Jacqueline also sexually abuse Felucia and Kyouko while holding them hostage at different points.
  • Rape Leads To Insanity:
    • Averted in Act III chapter 12; aside from having to be healed after taking a paralyzing hit to the spine, Tsukune walks away from getting raped by a ghoul-infected Kokoa none the worse for the wear. Considering he's spent most of his time at Yokai Academy being borderline harassed by five overzealous girls, it's not really that surprising.
    • Played straight with Felucia; by the time of Act IV chapter 6, she's been constantly tortured and sexually abused by Jovian and Jacqueline to the point that she's suffering Sanity Slippage, the one coherent thought she can focus on being that Dark had sworn to Hokuto that he was coming for her.
    • In Act VI, when Felucia retrieves Luna from Babylon's world, it's initially believe that Luna has been rendered catatonic by the sexual abuse she suffered at the hands of the monsters there. As it turns out, the Luna Felucia retrieved was just a doll in her image, and Hex saved Luna before things got to that point.
  • Rapunzel Hair: Astreal and Felucia are both described as having long hair. As shown in their official artwork, Astreal's hair reaches her waist, while Felucia's hair reaches her hips.
  • Readings Are Off the Scale: In Act IV chapter 2, Akua and Kahlua explicitly describe Jovian and Jacqueline's power levels as immeasurable.
  • "The Reason You Suck" Speech: Several examples:
    • In Act IV chapter 19, while beating up Hitomi, Inner Moka dishes one out:
    Inner Moka: You have some nerve to call yourself a teacher. All I see is a demented woman, one with no artistic talent of her own. So she has to take all the artists around her as her own pawns. Simply pathetic.
    • In Act VI chapter 25, Moka and co. (mostly Moka, but the others put their own opinion in) publicly berate the HDA for refusing to see that not all monsters are bad even after everything they've done to try and make peace with them:
    Moka: You arrested us. You took us away and scheduled us for execution just because we were monsters. We didn't want to cause any trouble. We didn't want anyone to get hurt. We only came to try to help, but you wouldn't listen to us. We didn't want to hurt you yesterday, but you gave us no choice. We had to free ourselves from being wrongfully imprisoned and accused of being enemies of mankind. Yes, we did harm and even kill some of the HDA when we broke out of your jail. We didn't want to, but we had to. You wouldn't listen to us. You wouldn't even try to understand. You just blamed us for everything because we were monsters and you were scared! We wanted peace with your race, and still do. But tell me honestly, did you want peace with us? Did you? Were you even willing to give us a chance, or does us being monsters automatically mean we're the devils? We told you that we would deal with monsters that were out of line, just as you deal with your own kind who cause trouble in your world, but the moment a monster acts out, you all jump to the notion of war! We risked out lives to help save you, to save all of you, and you still think we're nothing but horrible monsters! We exposed ourselves to you, told you everything you wanted to know about us. We wanted to live in peace with you! But the second a rogue monster causes a scene you blame all of us! You're unbelievable! We put an end to Fairy Tale! We stopped Alucard! We killed those that destroyed your school and city! My friend here even just shot that massive demon out of the sky by means that I can't even begin to fathom! What do we have to do to prove to you that we aren't evil?!
    Render: You know what? I was going to say sorry about having to kill some of your comrades the other day. I mean, hey, I didn't want to dice them into pieces. They were just trying to kill me and my smoking hot girlfriend, so of course I wasn't going to take that lying down. But it's obvious that none of you are sorry about the way you've been treating us or are even willing to listen to us. Our friend here just obliterated that demon above for you and you're aiming your guns at her again. The hell kind of manners is that?
    Mizore: You people are more of monsters than we are. You won't even give us a chance just because we're different; you think we're all the same. I could have used lethal force earlier while trying to help my friends escape the real evil monsters that were here when your police tried to shoot us. They didn't even ask questions or try to detain us; they tried to kill us on sight. But I didn't kill them. They're alive, and aside from having a few bruises, they'll be just fine.
    Leon: We stopped the monsters who were running around here causing havoc, but I guess that means nothing to you, does it?
    Akasha: I put an end to several large demons in your city, and this is the thanks I get? I see mankind's manners haven't changed in all these years.
    Moka: The HDA has been nothing but a barrier in any efforts to forming peace with you people; they treat all monsters as absolute evils regardless of their nature. I've laid my life on the line for your kind, and this is what I get for it, a gun to my face and accusations of being a plague in your world. I value life, no matter what it may be. Do you? We put a stop to the monster attack in your home. We tried to save as many lives as we could. We've begged you to listen and allow us the chance to explain what happened, yet you still point that thing at me. You want to kill me just because I'm a monster? Can there really be no peace between our worlds? If so, then go ahead and shoot. You won't get an easier shot than this. Just remember that we're willing to give peace a chance, but this monster in the darkness, the one that has attacked both our worlds in his quest for total domination... he will not be so merciful as to give you a similar chance.
    • In Act VI chapter 30, when Hothorne asks her how she expects him to just believe her story about Babylon and trust that they're telling the truth, Moka is quick to turn his own words against him, pointing out that he has no room to talk to her about trust considering the HDA's Van Helsing Hate Crimes mentality:
    Moka: You're one to speak about trust. How can we even trust you after how you treated us? We protected you from Alucard, we exposed ourselves willingly and told you everything you wanted to know about us, we've cooperated with your governments and even had three of our own students join your school as an act of peace. You're the ones that throw us all in the same lot when one of us acts out; you're the ones that have trust issues. Humans shot at us yesterday, tried to kill us all without even listening to us or willing to hear reason, yet I don't assume all humans are evil and want to kill us. There was a human girl who risked her life to free us, her name was Sandra and she gave her life helping us. She died because her own kind shot her, killed her like a common criminal all because she wanted to help those she knew were innocent. You treat all of us like evil monsters, like we're all out to destroy humanity and ravage the earth. Well, those are nothing but children's stories, Mr. Tamaka. Not all monsters are the devils. But there is one that's worse than the devil, and he's targeting both of our worlds for annihilation. So, tell me this right now, is this going to be a free-for-all, or do you want to have allies who can help you against this threat?
  • Reasonable Authority Figure:
    • The elder angel who serves as Rason and Gabriel's superior is initially the only angel besides Rason willing to give monsters a chance, and arranges for Rason to attend Yokai Academy to prove his point.
    • Hothorne Tamaka, the director of the HDA. Unlike most of the others, he actually does believe that some monsters can be good and meets with Moka and Akasha in Act VI to negotiate.
  • Red Baron: Talon has built up a reputation as "the Fairy Tale Killer."
  • Redemption Rejection: For the first few chapters of Act IV, Luna's evil sister, Falla, appears willing to clean up her act through several acts of kindness... but in chapters 10 and 11, just as Luna is convinced that Falla has changed and finishes the spell to restore her magic, Falla promptly drops the act and slices Luna in half before cruelly gloating to the others that her attempts to change were all just an act to dupe Luna into giving her her magic back. By the end of chapter 11, however, Falla is killed by a far more genuinely benevolent Alternate Timeline version of herself, who takes her place in the mainstream timeline.
  • Reformed, but Rejected: Throughout most of Act IV, most of the other members of Tsukune's group refuse to believe that Akua and Kahlua can truly atone for what they did while part of Fairy Tale, especially since they nearly killed the group and were helping Kiria in a plan that would have destroyed the world; Moka and Kokoa themselves openly state that, as far as they're concerned, Akua and Kahlua are beyond saving and Tsukune is just wasting his time. Dark, having once worked for Fairy Tale and killed innocents himself, is more understanding, and the others agree to at least give them a fair chance after he reminds them that he worked for Fairy Tale once as well.
  • Refusing Paradise:
    • Upon her definitive death in Act IV, Felucia is offered a place in Heaven, but instead explicitly requests to go to Hell so she can follow up on her earlier See You in Hell threat to Hokuto and the Kikion sisters and spend eternity making them suffer for torturing and molesting her. After the destruction of the Kikions' souls in the next arcs, Felucia accepts an offer of a Redemption Quest from the Lord of Hell to get into Heaven because, without them to torture, she sees no point in staying in Hell anymore.
    • In Act VI chapter 39, Akasha reveals to Moka that she has been Dead All Along; she was offered a place in Heaven by the Almighty, but refused to accept it because, having been indirectly responsible for Alucard's initial rise to power, she feels she needs to actually earn it.
  • Running Gag: Several:
    • Dark often has trouble reading Mizore's lips because of her ever-present lollipop. On more than one occasion, he apparently thinks she's suggesting they make love in public.
    • Rason is the only one who lampshades Apoch and Astreal's tendency to Speak In Unison.
    • The angels in Heaven asking one another whether or not the girls' skirts are supposed to be so short.
    • Several of the Official Couples (Mokax Tsukune, Rasonx Kurumu, Ahakonx Yukari, etc.) often do a Held Gaze while simply repeating each other's names, often in the midst of a combat situation.
    • On several occasions, despite knowing of the existence of monsters and other such creatures, characters such as Ahakon and Kyouko are genuinely shocked to discover that Kou is a Talking Animal.
    • After running or other such physical exertion, Ruby complains of being exhausted, to which the others accuse her of being out of shape.
  • Sacrificed Basic Skill for Awesome Training: In Act VI chapter 19, Ceal admits to Complica that, having spent most of his life training to slay dragons, he never learned how to swim.
  • Sadist: Several characters fit the bill, especially the original Jovian and Jacqueline who served Hokuto and Evil!Falla, the latter of whom gleefully tears off her Good Counterpart's wings, arm, and leg before crushing her ankle in Act V chapter 35.
    Kyouko: You... how could you?
    Evil!Falla: Very easily, actually.
  • Satanic Archetype: The Lord of Hell, who is revealed in Act II to be Kurumu's biological father.
  • Saying Too Much:
    • In Act III chapter 41, Jovian ends up revealing that she is indeed a witch sister when she addresses Hokuto as "master."
    • In Act IV chapter 1, while trying to excuse Tsukune to Issa, Kokoa accidentally lets it slip that she turned Tsukune into a ghoul.
  • Screw the Rules, I'm Doing What's Right: Despite the angels' zero-tolerance policy on killing humans, Rason makes it clear that he'll do what's right no matter what. During Act VI, Gabriel ends up adopting this view upon seeing the HDA's Van Helsing Hate Crimes mentality firsthand.
  • Screw Your Ultimatum!: Arial, in her stubbornness, does this twice in regards to her obsession with Dark. In Act VI chapter 13, Rason and Gabriel warn her that she will have to answer directly to the Almighty if she goes near Mizore again; Arial quickly disobeys them and goes straight to Mizore's room to issue death threats and steal Mizore's wedding ring. In chapter 15, Moka openly threatens to tell Dark that Arial is anything but the perfect angel he sees her as unless she gives Mizore the ring back. Again, Arial refuses and outright says that if she has to make her case to the Almighty himself, then so be it; Moka is only stopped from telling Dark by Apoch and Mizore's insistence that revealing the Awful Truth to him will only create more problems than it solves.
  • See You in Hell: In Act IV, after enduring Hokuto, Jovian, and Jacqueline's tortures for so long, Felucia declares that, even if Alucard does destroy everything, when she dies, she knows the three will follow and she will be waiting for them in Hell to torture them back. While the three laugh it off at first, Hokuto briefly flashes back to this moment when Tsukune is about to finish him off in chapter 31, and Felucia goes so far as to refuse entry into Heaven to keep her word.
  • Self-Made Orphan: Taken Up to Eleven; Falla didn't just kill her own parents, she wiped out her whole race with the exception of herself and Luna.
  • Serial Rapist: The original Jovian and Jacqueline, during their lifetime, rape Felucia, Kyouko (twice), Apoch, and Astreal. In an aversion of Double Standard: Rape, Female on Female, Tsukune and co. are absolutely furious to discover this.
  • Sex Is Violence: From Act V onwards, Kurumu gains a Super Mode, physically presented by her wings, tail, and claws being enveloped in purple fire, that makes her powerful enough to go toe-to-toe with Tsukune after his Restraining Bolt has been removed. However, her sex drive increases in proportion to her strength, and if it goes on for too long, she'll try to get it on with Anything That Moves (while she prefers Rason when it gets to that point, she's also tried to force herself on Rin and Sun).
  • Sexual Extortion: Rather than just stealing her first kiss as in canon, Miyabi actually forces Mizore to have sex with him in exchange for him sparing her mother's life... a deal he does not honor.
  • Shipper on Deck: In Act VI, Arial openly favors having Felucia marry Dark over Mizore, completely uncaring about the three's feelings on the subject.
  • Shotguns Are Just Better: Dark and Kenzo's preferred method of getting Felucia to shut up, if only briefly, is by blowing her head off with a shotgun.
  • Shout-Out: In Act I chapter 33, Kokoa shows up to the school dance dressed as Freddy Krueger.
  • Shrouded in Myth: The chronofly species was very secretive until their near-extinction, though Ahakon's father had heard some stories about them.
  • Shut Up, Hannibal!:
    • In Act IV chapter 18, in response to Hitomi's rants that petrifying her students is right, Apoch gives her a rather violent one of these:
    Hitomi: What I'm doing is right! What I'm doing is just! What I'm doing must be done! [gets Impaled with Extreme Prejudice by Apoch]
    Apoch: And I'm doing... what you've had coming.
    • In Act IV chapter 27, Tsukune gets such a moment with Hokuto:
    Hokuto: So naïve to the ways of the world, Tsukune, so full of optimisn and hope as your girlfriend here. I, however, have seen the world for how it truly is, and what I am doing is right, Tsukune.
    Tsukune: You know nothing of the world, Hokuto!
    • In Act V chapter 37, Kyouko gives one to Evil!Falla as well while beating her up:
    Evil!Falla: You miserable little insect! I'll tear you apart for that!
    Kyouko: FUCK YOU!!
  • Single-Target Sexuality: Felucia is strictly Dark-sexual, outright stating that he's the only man she could ever love.
  • Smug Snake: Throughout Act III chapters 30 and 31, Kano simply laughs off the girls' threats as he's blackmailing and photographing them, confident that, between the pictures he's taken and their current shaky situation in the academy, he's untouchable. He's proven wrong at the end of chapter 31 when Luna eats the entire back half of his head as he's about to force himself on Mizore.
  • Spared by the Adaptation: Both Kahlua and Mikogami survive the final battle with Alucard.
  • Speak Ill of the Dead: In Act III chapter 40, Falla flat-out tells Luna that Complica was a disgrace to their species and that she was glad she died. Keep in mind that Complica is her little sister.
  • Speak In Unison: Part of the Ezrana sisters' Verbal Tic.
  • Split Personality: As a result of being infected by the ghoul in Act III, Kokoa develops two different personas: one under the control of the ghoul, and one that simply wants to mate with Tsukune whether he's willing or not. She's cured of both when Dark extracts the ghoul's spirit from her body and absorbs it.
  • Spotting the Thread: In Act I chapter 30, after their Divide and Conquer tactics work, Rarosun and Surason decide to give Rason and Dark the final push to kill each other by morphing into Mizore and Kurumu and egging them on to do so. Unfortunately for them, by that point, Mizore has been marked as Dark's soul mate, and Rason can sense his bond with Kurumu, thus easily allowing the boys to see through their disguises and realize they had been tricked.
  • Stab the Scorpion: In Act II chapter 21, Dark seemingly aims a gun at Rason, about to shoot him, to which Rason yells, "Whoa, whoa! Same team!" Dark fires... and headshots a Fairy Tale operative that had snuck up behind Rason.
  • Stealth Expert: In Act VI, Talon manages to sneak into the Shuzen castle unseen by both the guards and Akua and Kahlua themselves not once, but twice.
  • The Stoic: Dark is nearly always cool, calm, and collected, shows little emotion, and is typically seen with a blank expression on his face. When Mizore is in danger, he becomes Not So Stoic.
  • Story-Breaker Power: In Act III and onwards, Luna and Falla's chrono magic easily makes them among the most powerful of Tsukune's gang, if not the most powerful, to the extent that they were instrumental in the gang's defeat of Alucard in Act IV. Naturally, the author keeps coming up with ways to keep them from going all out to prevent them from rendering everyone else useless, such as the Almighty's law forbidding them from actual Time Travel, the risk of chrono dementia, the risk of getting preyed upon by chrono wraiths, and Babylon keeping track of their chrono magic in order to capture them.
  • Straw Nihilist: In Act IV, Hokuto states that both humans and monsters are equal bastards and could never hope to co-exist, hence why he's trying to resurrect Alucard to destroy the world:
    Hokuto: You see, I've seen some truly horrible things in life, Moka. You'd be surprised how similar humans and monsters really are. How they both claim they desire peace, yet both destroy everything around them. How they both claim they can love, yet they both hurt and attack everything different. You see, it doesn't matter if you are human or a monster, a life is a life. And all lives are trash. All lives are a waste. Everything that lives only wants to live for the sake of living, and will step on anything to get its wish. Monsters, humans, they all claw at any vain attempt to live on, both killing anything that seems different or strange in fear of its own existence. There is no difference, Moka. All life is evil.
  • Stubborn Mule: Throughout Acts V and VI, Arial takes this trope Up to Eleven, repeatedly insisting that she and Dark are soul mates and brushing off all attempts to reason with her; not even getting beaten within an inch of her life by Mizore gets through to her. It's only after her actions nearly drive Dark over the Despair Event Horizon and get him hit by an HDA vehicle that she finally listens to reason, and even then, she stubbornly refuses to accept Dark and Mizore's relationship.
  • Suicidal Cosmic Temper Tantrum:
    • In Act III chapter 50, Luna, after killing Kiria, has gone so insane with grief over Rason's death that she's willing to let the Chrono Displacement spell destroy the world, but Tsukune manages to get through to her and change the spell date to one day, allowing him to go back and save everyone.
    • In Act IV, the extent of Hokuto's plan is to revive Alucard and then just sit back and watch as Alucard destroys the world, because he's firmly convinced that all life, human and monster alike, is an evil and meaningless plague that must be eradicated.
  • Super-Persistent Predator: Chrono wraiths, the natural enemy of chronoflies. Once they sense a chronofly, they will never stop hunting them until either they catch and eat them, or until the wraith itself is slain.
  • Super Soldier: Fairy Tale has made several of them, one such example being Talon Ryashen. As of Act VI chapter 49, it's revealed that they're also making clones of Tsukune's group and enhancing them with the improved Blackheart serum, thus greatly enhancing their strength while removing their limitations; the Mizore clone, for example, is heat-resistant and can produce ice with a temperature of absolute zero.
  • Superpower Meltdown: Koka nearly undergoes one in Act II, when her aura flares up to the extent that she starts to burn up from the inside. The ghoul inside Tsukune stops it by taking over and having Kokoa attack him to use up the built-up energy, stating that with the amount of power Kokoa has built up, he would be the only one to survive a direct hit.
  • Sympathy for the Devil: In Act VI, Kyouko is sympathetic to Talon's plight even though he's killing Fairy Tale operatives, including non-combatants and Unwitting Pawns, left, right and center, insisting that he's not evil and just angry at what happened to him. Apparently, compassion for those who try to hurt and kill others is an Aono family trait.
  • Take a Third Option: In Act VI chapter 2, Ceal presents Gabriel with a choice: either stand and watch as Ceal kills an HDA soldier, or kill Ceal himself to save said soldier's life. Gabriel takes a third option by shooting the soldier in the head, thus sparing him a slower and more agonizing death at Ceal's hands, but leaving him extremely guilt-ridden.
  • Taking the Bullet: In Act I chapter 4, Tsukune jumps in-between Moka and Mizore and takes a claw stab from the latter to protect the former.
  • Technicolor Fire: The flames Rathieal controls are red and purple.
  • Teeth-Clenched Teamwork: As shown in Act VI chapter 47, even as they're working together to try and find out what happened to their kids, Ageha and Tsurara can't resist being at each other's throats.
  • Tempting Fate: Several examples.
    • In Act III chapter 9, after Tsukune orders Kokoa to get all of the girls out of the boys' bathroom, Kurumu, being in the tub at the time, arrogantly brags to Kokoa that she's in water and there's nothing Kokoa can do about it. In response, Kokoa jumps right into the tub, says "I'll live," and bodily throws Kurumu out of the bathroom by the hair.
    • In Act VI chapter 42, Ruby remarks that she hopes they can actually take a bath for once without a fight breaking out. Naturally, Kokoa ends up finding out that Sun was spying on her and Gin having sex earlier, and promptly beats Sun into a coma in her rage.
  • Terrorists Without a Cause: Unlike the manga, where he was a member of Fairy Tale and had been serving as The Mole during his Security Committee days, Kuyou is depicted here as little more than an anti-human thug who attacks Yokai Academy in Act III chapters 40-42 to take revenge on Tsukune and Moka for his previous loss. On top of it all, he's nothing more than an Unwitting Pawn of Hokuto, who personally orchestrated Kuyou's attack on the academy solely to distract everyone while he broke into the school's secured levels and stole an Artifact of Doom.
  • Their First Time:
    • In Act II, Mizore gets hers with Miyabi thanks to Sexual Extortion, much to her horror. Dark, however, says that she has yet to actually have a first time.
    • Later, in Act III, under the influence of the ghoul infection, Kokoa rapes Tsukune and thus loses her virginity; while she doesn't enjoy the actual act because she was forced into it by the ghoul infection, Kokoa does find some small comfort in the fact that Tsukune was her first time.
  • There Can Be Only One:
    • In Act IV chapter 2, Akua and Kahlua note that when Fairy Tale tried creating more duplicates of Jovian and Jacqueline, the originals killed said duplicates because they didn't want to be duplicated.
    • As revealed in Act VI chapter 52, the Blackheart-enhanced clones of Moka, Ruby, Yukari, Kurumu, Kokoa, and Mizore all killed any other clones that Fairy Tale tried to make.
  • There Is No Kill Like Overkill:
    • As detailed under Extreme Melee Revenge above, Dark kills Miyabi very brutally in Act II. In this order, he slowly crushes all of the bones in Miyabi's arms and legs to powder before tearing them off one by one, punches him in the face with such force that his jawbone snaps clean off, and finally tears his spinal cord clean out of his body with his bare hands.
    • In Act III chapter 52, Ghoul!Tsukune overpowers Kiria and, in this order, rips both of his arms off, tears most of Kiria's internal organs, as well as a chunk of his spine, out with his bare hands, and finally crushes Kiria's skull with his bare hands before tearing it off.
    • In Act IV chapter 28, Apoch and Astreal double-team and kill Jovian in this manner, with Apoch slicing her in half and Astreal shooting her in the head.
  • There Was a Door: In Act III chapter 51, Dark smashes a window rather than use the door to get to the Blackheart storage. When Gin points out the door, Dark's response is a deadpan "In a hurry."
  • This Cannot Be!:
    • In Act IV chapter 18, Hitomi has this exact reaction when Inner Moka breaks free of the petrifaction; as it turns out, when Hitomi petrified Outer Moka, the rosary, as well as its seal, was petrified as well.
    • After having things go his way for most of Acts III and IV, this is Hokuto's reaction in Act IV chapter 31 when the fully-vampirized Tsukune starts kicking his ass.
    • Similarly, in Act IV chapters 28 and 29, Jovian is completely taken aback when Apoch proves that she and Jacqueline are Not So Invincible After All by successfully penetrating her barrier with her Laser Blade, and then using said blade to deflect her Hand Blasts.
  • This Is for Emphasis, Bitch!: In Act IV, Astreal quips "Let's see you fly, bitch!" before subjecting Jacqueline to a Disney Villain Death.
  • This Is Unforgivable!:
    • In Act III chapter 44, this is Kokoa's word-for-word reaction upon the revelation that Akua and Kahlua are working for Fairy Tale and have been all along.
    • During the climax of Act IV, the entire gang has this reaction when they discover that Hokuto, Jovian, and Jacqueline had taken Tsukune's family hostage. They also have this reaction doubly so when they discover that Jovian had spent the entire time sexually abusing Kyouko For the Evulz, with the others flat-out telling Jovian during chapter 26 that she's going to Hell for what she did to Kyouko.
    • In Act IV chapter 31, right before laying the smackdown on Hokuto, Tsukune flat-out tells him to his face that Hokuto will never be forgiven for everything he's done. Considering the fact that Hokuto's list of Kick the Dog moments include such gems as kidnapping and brainwashing Felucia, setting Kuyou loose on Yokai Academy, letting Jovian and Jacqueline rape and torture Felucia to the point of Sanity Slippage, and being indirectly responsible for the deaths of Felucia, Kenzo's gang, and the original Ezrana sisters, it's perfectly justified.
  • Thou Shalt Not Kill Muggles: It's been stated that angels are forbidden to harm humans for any reason unless said humans die with sin; this also applies to monsters who were once human, such as Hokuto. Being forced to Mercy Kill an HDA soldier to spare him a more agonizing death at Ceal's hands causes a lot of guilt for Gabriel. Now that Rason is the guardian angel of the monster world, he is the only exception.
  • Time Travel for Fun and Profit: Kiria's Evil Plan in Act III: use the Chrono Displacement spell to send several Blackheart-infected monsters back in time, subjugate the humans, and kill off the dark lords and any other monsters who could pose a threat to him, thus leaving him in charge of the entire world. Upon his defeat, however, Hokuto remarks that, since Kiria got the idea from reading manga, the plan was most likely doomed from the start.
  • Token Human: Kyouko has become this for the group as of Act VI.
  • Too Dumb to Live: In Act III, Gin decides to turn to Dark of all people for help after stealing Apoch's underwear; the others actually ask him if he's suicidal.
  • Too Kinky to Torture: Jacqueline, as indicated in this exchange in Act VI chapter 43:
    Jacqueline: Um, you can punish me later for it if you want, sister.
    Jovian: Somehow, I doubt you'll learn anything if I do.
  • Too Much Information:
    • In Act III chapter 7, this is the gang's reaction when Ruby informs the newly revived Apoch and Astreal of everything Fairy Tale did with the army of duplicates they made... including the fact that they also used several clones as sex toys.
    Felucia: Great, they're back for twenty minutes, and you scar them for life.
    • In Act VI chapter 13, this is everyone's reaction when Kokoa reveals to Sun that she had sex with Gin in his full werewolf form and boasts to Sun that she most likely couldn't handle doing the same.
    Moka: For crying out loud, don't you have any shame?!
  • Took a Level in Badass: Several examples.
    • In Act I, Tsukune can barely hold his own against a generic ogre without help. He learns to control his vampire powers over the course of the series, and by the time he's fully vampirized during the climax of Act IV, he completely pounds Hokuto after the latter goes One-Winged Angel.
    • Moka also learns to access some of her power so she can fight without always having to rely on Inner Moka, though Inner Moka is still the stronger of the two.
  • Traumatic Superpower Awakening: A variation occurs in Act I chapter 4. When Tsukune is badly injured after Taking the Bullet for Moka, courtesy of a jealous Mizore trying to Murder the Hypotenuse, Inner Moka is so horrified and outraged that she actually bypasses her rosary's seal to give Mizore a No-Holds-Barred Beatdown.
  • A Truce While We Gawk: In Act III chapter 8, Dark is outright trying to murder Tsukune, convinced that Tsukune can't be trusted to keep the ghoul contained, with Mizore and Felucia agreeing with him and fighting Moka and Kokoa to prevent them from intervening. All fighting stops when the edge of the cliff Dark and Tsukune are fighting on gives way, forcing the four girls to drop everything to pull the boys back up... which leads to Dark, Mizore, and Felucia seeing just how durable the Holy Lock is and accepting that the ghoul is indeed sealed away.
  • True Companions: Even after they find their own boyfriends and move on from him, the various members of Tsukune's harem, as well as said boyfriends, remain close friends with Tsukune to the extent that, in Act III chapter 52, he openly states that he would gladly die for them and can't imagine living without them.
  • Turned Against Their Masters:
    • Dark turned on his master after said master forced him to kill a little girl.
    • Apoch and Astreal fled from their original master when they got fed up with being used to harm innocents.
    • In Act V, when Babylon goes back on his word on setting them free, Rin, Ran, and Ren immediately free all of the people they had charmed for him out of spite.
    • Later in Act V, Babylon pulls the souls of Jovian, Jacqueline, and Evil!Falla out of Hell and forces them to work for him. As soon as the three learn of Pandora's Box, however, they turn on him with the intent to take the box for themselves... only to get killed again and wiped from existence completely for their trouble.
  • Underestimating Badassery: In Act IV chapter 13, while fighting the new Apoch and Astreal, respectively, Mizore and Kurumu both assume they'll be the same as their Dead Alternate Counterparts. They fail to consider that, since these witch sisters were the girlfriends of Dark and Rason, respectively, in their original timeline, Apoch and Astreal would have of course Took a Level in Badass, and are only stopped from getting badly hurt at the least by Rason and Dark's interventions.
  • Undying Loyalty: The original Kikion sisters' only real redeeming trait is that they're completely loyal to Hokuto no matter what; Akua notes in Act IV chapter 2 that, even during their worst tantrums, they never raised a hand against Hokuto, and he was the only one who could get them to calm down.
  • The Unfettered:
    • In Acts III and IV, Hokuto goes to ludicrous lengths for his plan, including having Felucia kidnapped and brainwashed to serve him after letting Jovian and Jacqueline brutally torture and rape her to the point of Sanity Slippage, setting Kuyou loose on Yokai Academy for the purposes of a distraction, and deliberately breaking The Masquerade in an effort to get Tsukune and co. killed by the humans and prove to Moka that his nihilism is completely justified.
    • In Acts V and VI, there is literally nothing Babylon won't do in order to conquer whatever worlds he can find, up to and including having members of powerful endangered species kidnapped to be used as breeders for his army and razing entire populations to the ground in pursuit of his targets.
  • Ungrateful Bastard:
    • In Act VI chapter 25, Moka and co. chew out the HDA for continuing to dismiss all monsters as evil even after she and her friends risked their lives to defeat the rylo that was attacking the city.
    • In Act VI chapter 42, Mizore saves Arial from being killed by an enraged Kokoa, who has unleashed her overcharge. Arial scornfully remarks that all Mizore really did was knock her down and that she could have taken Kokoa down on her own; when Mizore points out that Kokoa was on fire and that Arial, as a snow girl, would most likely have been incinerated by simply being near her, Arial openly dismisses it and hits her in the forehead with a shard of ice.
  • Unhand Them, Villain!: While confronting Hokuto on his airship in Act IV chapter 27, Tsukune demands that he let Moka go. Hokuto obliges... by first stabbing Moka in the gut with the Ithirill Blade to collect the blood sample he needs for Alucard's revival, and then having his mooks bodily throw her out of the airship.
  • Uniqueness Value:
    • In Act III, Rason states that the Holy Lock he gave Tsukune is one-of-a-kind and can only be repaired by the Almighty Himself. Imagine their surprise when it turns out Hokuto has a Holy Lock of his own, and Jovian can repair it, albeit temporarily. Later, in Act IV chapter 16, the angels produce two more Holy Locks to restrain Luna and Falla with.
    • In Act IV chapter 2, Akua mentions that Jovian and Jacqueline hated the idea of being duplicated to the extent that whenever Fairy Tale tried to summon more of them, the two promptly killed said duplicates on the spot.
  • The Unmasqued World: During the climax of Act IV, Hokuto deliberately breaks The Masquerade to the entire human world in an effort to prove to Moka that his nihilism is justified and humans and monsters can never co-exist, with the unmasking being complete with Alucard's revival. The next two acts center on Tsukune and co. trying to prove him wrong.
  • Unskilled, but Strong: When she comes to Earth from Heaven in Acts V and VI, Arial is still technically dead and thus does not have the limitations of a living body; thus, there is no limit to how much ice she can produce at once. However, she's a poor fighter; in Act VI chapter 8, she catches Mizore by surprise and beats her in a fight, but come chapter 17, Mizore's superior fighting skills and technique ultimately allow Mizore to come out on top.
  • Unstoppable Rage:
    • In Act IV chapter 2, Akua notes that, when provoked, Jovian and Jacqueline destroyed entire Fairy Tale facilities in their fits of rage, and only Hokuto could calm them down; according to Akua, the Kikions' temper tantrums put Kahlua's Berserker Tears to shame.
    • In Act VI chapter 42, Kokoa flies into one when she discovers that Sun was spying on her and Gin having sex, and really flies off the handle when Sun outright tells her that she's not good enough for Gin, proceeding to punch Sun through a wall and chase both Felucia and Sun through the house in a rage until Arial encases her in ice. By chapter 44, she's thawed and still pissed off to the point that the others have to chain her to the ground, while she's reduced to snarling and growling like an animal.
  • Unwitting Instigator of Doom:
    • As revealed in Act III chapter 15, while making Yukari a new wand, Apoch and Astreal misread the instructions to do so and make her the wrong one. As a result, Yukari gets Drunk with Power and tries to kill the gang in a fit of rage, causing Tsukune to break two more links on his Holy Lock in order to stop her and destroy the wand. All of that chaos happened simply because Apoch and Astreal misread an instruction booklet.
    • It's also revealed over the course of Act III that Kenzo had had one of his men follow Dark the night he hid Felucia's spirit artifact to ensure it was in a safe place. While he was well-intentioned at first, Hokuto finds this out and sends Kuyou after Kenzo in order to discover it's location. The end result: Kenzo ends up dead by Kuyou's hands, and Hokuto gets his hands on Felucia's spirit artifact and uses it to extort Felucia into being his minion.
  • Unwitting Pawn:
    • In Act III chapter 42, it's revealed that Hokuto lured Kuyou to Yokai Academy by exploiting his desire for revenge on Tsukune and his friends, using the chaos to his advantage to steal the artifact he needed for his plan.
    • Akua and Kahlua helped Kiria in his scheme to rewrite history with Chrono Displacement, planning to make their father one of the top dark lords of the world in the new timeline. In Act III chapter 52, they have a Heel Realization when they realize that Kiria's plan would have been more for his own benefit than any other monsters', and that he would have infected them with Blackheart and sent them back to kill their father as part of said plan.
  • Upgrade vs. Prototype Fight: In Act IV, Apoch and Astreal battle Jovian and Jacqueline, and after much trial and error, manage to defeat them.
    Astreal: Who's obsolete now?
  • Vampires Are Sex Gods: When a particularly powerful vampire unleashes his aura, female vampires within the vicinity often experience The Immodest Orgasm to the extent that they're left literally incapacitated from the experience. Tsukune used this to his advantage in Act III to defeat Akua and Kahlua without killing them, and, as revealed in Act VI chapter 39, Alucard actually defeated Akasha by doing the same; the shame of letting it happen and thus being indirectly responsible for Alucard's rise to power remains with Akasha to this day.
  • Vein-O-Vision: In Act V, Tsukune has this happen whenever his bloodlust flares up.
  • Verbal Tic: Apoch and Astreal have a habit of addressing everyone as "Mr." or "Ms.", as well as speaking in unison.
  • Villainous Breakdown: In Act IV chapters 27 and 28, Jovian and Jacqueline, having been unparalleled Smug Supers and convinced of their own invincibility beforehand, completely flip their shit when Apoch uses her Laser Blade to both shatter their supposedly-unbreakable barriers and deflect their supposedly-unstoppable energy attacks.
  • Villainous Friendship: Hokuto and Kiria. In Act III, it's noted that Hokuto agreed not to enact his plan to revive Alucard unless Kiria failed in his own plan to use Chrono Displacement to rewrite history, even though Hokuto was firmly convinced that Kiria's plan was doomed from the start.
  • Villainous Incest/Twincest: Jovian and Jacqueline definitely have a thing for each other.
    Hokuto: Such strange love you two have.
    Jovian & Jacqueline: What do we care? We're made from magic.
  • Vitriolic Best Buds: Tsukune's entire posse. They may have their differences, and fight and even try to kill each other on a semi-regular basis, but even through all that, they're True Companions to the bitter end.
  • War for Fun and Profit: A mix of this and Despotism Justifies the Means is Babylon's entire motive.
  • Was It Really Worth It?: In Act VI chapters 33 and 34, after Gabriel loses his wings and angelic status to Hex's game, the others of the group unanimously agree not to play Hex's game again as nothing they could possibly gain from it is worth the risk, especially since Gabriel lost everything to the game and gained nothing in return. Ran even flat-out states that, while she wanted to find Rin, she didn't want it to be at such a cost.
  • "Well Done, Son!" Guy: The reason Akua and Kahlua worked for Fairy Tale in the first place was to try to help Issa, making him one of the top dark lords of the new timeline; of course, they were unaware that Kiria had planned all along to infect them with Blackheart and then send them back in time to kill Issa and destroy his empire from within.
  • Well-Intentioned Extremist: Hokuto certainly thinks of himself as one with his plan to raise Alucard and destroy the Earth, but anyone and everyone around him can tell right off the bat that he's nothing but a nihilistic madman.
  • What Measure Is a Non-Human?:
    • Rason was originally banished from Heaven because he killed a male human who was about to rape a female monster; apparently, as far as the angels are concerned, even the lives of murderers and rapists have more value than those of monsters. As of Act IV, the other angels have noticed and accepted that monsters can be good too and have designed a Heaven for them.
    • Both Ghaldin and Fairy Tale view the Ezrana sisters as nothing but living weapons and tools to be used however they please, whereas Tsukune's posse think the exact opposite.
  • What the Hell, Hero?:
    • In Act I, Dark calls out the members of Tsukune's Unwanted Harem for constantly bickering over him and not just letting him choose which one he wants to be with, and when he does choose Moka and they start arguing again, he does so once more by their seeming failure to respect Tsukune's choice, describing them both times as pathetic. The girls even acknowledge he's completely right.
    • In Act II chapter 24, after Apoch and Astreal nearly kill Yukari over Ahakon and are beaten up by Inner Moka in return, Ruby angrily chews them out for it, stating that just because they're dating Ahakon doesn't mean they can treat Tsukune and co. like dirt.
    • A minor example: in Act III chapter 13, after Mizore explains that Dark's claims that he'll kill Tsukune when Kokoa's debt to the latter is repaid were just a Jerkass Façade made so Dark would have an excuse to keep him alive, she tells the others that Dark isn't that cold and to give him more credit than that.
    • In Act III chapter 32, after Kano is killed, Tsukune, Rason, Dark, and Ahakon all angrily storm off to the headmaster and chew him out, as it was because of the headmaster's warning that the group would be separated if they started another fight that their respective girlfriends let Kano blackmail and take dirty pictures of them. The headmaster acknowledges his mistake and agrees to let them exercise their right to protect themselves should any of the other students try to make trouble for the group again.
    • The gang calls out the headmaster again in Act III chapter 42 and 44 over the fact that both Kuyou and Fairy Tale had just attacked the academy one after the other, and he just sat there and did nothing while they and the other students fought for their lives.
    • In Act IV chapter 13, after the new Apoch and Astreal pick fights with Mizore and Kurumu, respectively, over Dark and Rason, respectively, Dark and Rason step in and call them out for their single-mindedness and failure to realize that they're not the same boys they knew; Dark even flat-out calls Apoch an idiot.
    • In Act IV chapter 16, Rason, Kurumu, Astreal, and Ruby all call out the angels in Heaven and the Almighty himself for refusing to take action against Hokuto and his plan to resurrect Alucard out of their Lawful Stupidity. Kurumu sums it up best:
    Kurumu: This is insane! You know Hokuto is going to destroy the world, and yet you're picking on Luna and Falla?! What the hell is wrong with everyone in Heaven?
    • In Act VI chapter 2, Ceal takes the time to call Gabriel out for continuing to stick to the angel's code that humans are sacred and must be protected until they die with sin, especially since the HDA is trying to kill him and the others without mercy or hesitation even as they speak:
    Ceal: They nearly killed those two witches behind you. They've been trying to kill us this entire time. They're going to kill your friend and the others here tonight. And you're calling them sacred?
    • In Act VI chapter 20, Moka hits her breaking point in regards to Arial, Ran, and Sun being Clingy Jealous Girls and blows up on them.
    • In Act VI chapter 34, after Gabriel loses Hex's game, as well as his wings and right to return home from Heaven as a result, Falla chews Luna out for siding with Hex over Gabriel, especially since Gabriel only played Hex's game in the first place because he was trying to help save Complica and just gave up everything for nothing.
    • In Act VI chapter 44, Ruby chews Kokoa out for leaving Sun in critical condition, remarking that even if Ceal does manage to heal her, there's no guarantee that Sun's brain survived the hit.
  • What the Hell, Townspeople?: After being blackmailed by Kano in Act III chapter 30 on top of all of the other mistreatment from the other students, Felucia justifiably has this reaction. By the next chapter, she's so sick of the other students' harassment that she actually suggests to the others that they let Kuyou kill everyone when he strikes.
    Felucia: These are the creeps we're protecting from Kuyou? Seriously?
  • Wife-Basher Basher: Harming or otherwise mistreating women around Dark is a very bad idea.
    Dark: I despise those who don't treat women right.
  • Witch Species: In addition to generic witches, we have mages like Ahakon. Unlike witches, mages are able to cast spells without wands, but have smaller magical reserves. As the fic continues, it also introduces sub-species of mages, such as catalyst mages, mimic mages, and battlemages. There's also warlocks, who differ from witches in that they don't need wands and focus on Non-Elemental magic to cause direct pain and injury, such as chains and curses.
  • With Great Power Comes Great Insanity: If chronoflies use their time magic too much, it can be detrimental to their mental health, which others refer to as "chrono dementia." In extreme cases, it can even be fatal.
  • Woobie, Destroyer of Worlds: Act VI has one in Talon Ryashen, the "Fairy Tale killer." He was just an ordinary boy until Fairy Tale kidnapped him off the streets and used him as a Super Soldier experiment, turning him into a Half-Human Hybrid by injecting him with Alucard's blood. He escaped the facility when the experiments were completed, and was rejected by his family because of what he had become; as a result, he has embarked on a crusade to kill anyone and everyone who is or was part of Fairy Tale, including Unwitting Pawns, receptionists, and those who turned on the organization, such as Dark, Akua, and Kahlua. As he puts it, Fairy Tale took everything from him, and he has nothing left to live for but revenge on the organization.
  • The Worf Effect:
    • Apoch and Astreal's reputation as the perfect shield and the perfect sword is tarnished as the series goes on, with more and more characters being able to break Apoch's barriers and survive Astreal's energy beams.
    • Jovian and Jacqueline are set up as Invincible Villains with impenetrable barriers and unblockable energy attacks. Come Act IV, and it turns out the new Apoch's Laser Blade can cut through their barriers and deflect their attacks.
    • The first sign of just how tough a rylo is in Act VI? Kurumu using her Princess of Hell Super Mode doesn't even faze it.
    • The rylo is also on the receiving end of this; in Act VI chapter 25, Astreal uses the Artimus Arrow spell, which completely obliterates the supposedly Nigh Invulnerable demon with one shot.
  • Would Hit a Girl: Somewhat paradoxical to his Wife-Basher Basher status, Dark doesn't discriminate against hitting girls, most notably by blasting Felucia's head off with a shotgun. Of course, Felucia can regenerate.
  • Would Hurt a Child/Wouldn't Hurt a Child: Several characters hold one of these two views.
    • Dark states that, even for the denizens of Hell, the act of killing a child is completely abhorrent and looked down upon everywhere. Unfortunately, his then-master had no such restraints and forced him to kill one... which proved his undoing.
    • The members of Fairy Tale have absolutely zero qualms against razing entire villages to the ground if the inhabitants of said villages don't agree to their demands, and certainly don't discriminate against children. In fact, when the readers are first introduced to Ahakon in Act III, he's fleeing from a Fairy Tale squadron out for his blood.
    • In Act VI chapter 20, Ran bodily lifts Yukari off the ground and is about to punch her in the face in a fit of jealousy before Arial freezes her on the spot.
    • In Act VI chapter 47, Render calls out a member of the HDA for trying to kill monster kids even if they were Just Following Orders, sarcastically quipping that he "must feel so proud." Said HDA officer bitterly remarks that he doesn't care if the monsters responsible for the attack on the school during Act V were kids because said monsters killed his daughter.
  • Wrecked Weapon: Both Yukari and Ruby have gone through multiple wands over the course of the series.
  • Yandere: This is Arial's attitude towards Dark for most of Acts V and VI, being extremely possessive over him to the extent that when she finds out that Dark is dating Mizore, she brutally attacks and nearly kills the latter in a fit of rage. Later, in Act VI chapter 13, Arial breaks into Mizore's room and seals her status as this by issuing a very chilling death threat:
    Arial: Dark is my demon. He's going to be my husband, and only I'm going to have his mark over my heart. Do you hear me? If you kiss him, I'll claw off your lips. If you touch him, I'll cut off your hand. If you take his seed into you, I'll carve it out of you. He belongs to me. Everything about him is mine.
  • Yes-Man:
    • Both Mizore and Felucia have become this to Dark, being essentially unable to say no to anything he says. If he says Tsukune is a threat even with the Holy Lock holding the ghoul at bay, then Tsukune's a threat. If he says Tsukune is safe, then he's safe.
    • Gabriel also assumes this role early on in Act VI, being insistent on following the Almighty's law that humans are sacred and cannot be harmed by the angels even though the HDA is trying to kill him and his friends without mercy or hesitation. Ceal even lampshades it:
    Ceal: If your lord told you to kill yourself, would you?
  • You Are Too Late: Despite Tsukune's best efforts during the climax of Act IV, he is unable to defeat Hokuto before he unleashes Alucard.
  • You Are Worth Hell:
    • In Act III chapter 52, when the others ask why he used the Chrono Displacement spell to save them, Tsukune informs them that they're his friends, and if given the choice, he would gladly give his life for theirs a second time.
    • In Act VI chapter 49, Ten-Ten requests that Issa and the other dark lords at least let herself and Ling Ling through to the human world to see Fang Fang and her husband, willing to be closed off from the monster world forever as long as she can have her family together again.
    Issa: Your dedication and willingness to go through so much for your loved ones is commendable.
  • You Did Everything You Could: In Act IV chapter 29, when Apoch and Mizore are blaming themselves for Felucia's death, Dark invokes this trope, reminding them that Apoch and Astreal killed Jovian and Jacqueline, the ones who enslaved Felucia in the first place, and Mizore stayed with Felucia to the end to ensure her escape, and that's all he could have asked of them.
  • You Have Got to Be Kidding Me!:
    • In Act VI chapter 25, this is Gabriel's reaction when he sees that the HDA are still holding Moka and the others at gunpoint even after Astreal shot down the rylo that was attacking the city.
    • In Act VI chapter 42, this is Mizore's completely understandable reaction when her attempt at bonding with Arial leads to Arial continuing to criticize her and insist that Mizore is nowhere near good enough for Dark, as well as near the end of the chapter, when Arial cares more about the fact that Felucia saved Sun from an enraged Kokoa than the fact that Mizore saved her ungrateful life from Kokoa mere seconds before.
  • You Have Outlived Your Usefulness: In Act III chapter 42, after stealing the Artifact of Doom he needs for his plans, Hokuto outright declares that Yokai Academy has no further use to him and gives Kiria free rein to send a Fairy Tale squadron to the school to wreck the place.
  • You Watch Too Much X: It's heavily implied in Act III and later Act VI that Kiria got his plan to use Chrono Displacement to rewrite history from reading manga, hence why Hokuto believed that said plan was doomed to fail from the start.
  • You Wouldn't Like Me When I'm Angry: At times, Inner Moka manages to bypass the rosary's seal when Moka is under great emotional stress. Examples include Act I chapter 4, when she witnesses Tsukune Taking the Bullet for her to stop Mizore from killing her, and Act VI chapter 20, when her hair briefly turns silver while she's angrily telling Ran, Sun, and Arial to just accept that their respective crushes are taken.
  • Your Head Asplode:
    • After he's freed from Ghaldin's control in Act I, the first thing Dark does is stomp the skull of Ghaldin's body into mush.
    • In Act III chapter 40, Tsukune finishes off Kuyou by shattering his head with a punch.
    • Discussed: in Act VI chapter 42, Kokoa critically injures Sun with a Megaton Punch to the face; as revealed in chapter 44, Kokoa's attack pulverized Sun's eyes and cracked her skull, and if she had used just a little more power, she would have shattered Sun's skull completely.
  • You're Insane!:
    • In Act IV chapter 17, when Ruby conjures a bazooka loaded with the love-struck potion antidote and orders Akua to shoot those affected, Akua rightfully asks, "Are you out of your fucking mind?"
    • Later in Act IV, when Hokuto is going on about his nihilism, both Tsukune and Moka tell him he's out of his mind.
    • In Act V chapter 29, when Ceal reveals that he intends to slay a dragon, both Render and Leon outright question his sanity.
  • Zombie Advocate:
    • Rason is determined to prove to his superiors that monsters can be good too. By Act IV, he's finally succeeded.
    • Kyouko has become one as of Acts V and VI, explicitly telling several of the other girls in the group that even if they are monsters, she knows they aren't evil and trusts them with her life.
