The numerous Original Characters featured in Rosario Vampire: Brightest Darkness.

---

Rason Miyamosa

An angel who enrolls in Yokai Academy at the beginning of Act I, joining Tsukune's posse and becoming romantically involved with Kurumu.

• Affectionate Nickname: Kurumu often calls him "angel boy," and is the only one who he tolerates doing so.
• Audience Surrogate: He's the only one who ever really comments on the Ezrana twins' habit of speaking in unison, or that the various new students always seem to end up in Ms. Nekonome's class.
• Beware the Nice Ones: Rason is every bit a Nice Guy and easy to get along with, but it's shown time and again that he is not one to be trifled with when pushed.
• Brainwashed and Crazy: He's briefly controlled by Apoch and Astreal's former master in Act I chapters 12 and 13.
• Clothing Damage: Constantly shreds his shirts when he sprouts his wings.
• Determined Defeatist: In Act IV chapter 23, the way he sums up the group's predicament with having to save Tsukune's family from Jovian and Jacqueline has shades of this:
  Rason: They have nearly unlimited power, and no regard for life around them. Their shields are supposedly unbreakable and their attacks can destroy virtually anything. And we have to split up our fighting power to attack two of them in different places in the human world where they not only have Tsukune's mother and cousin hostage, but will also be around other humans as well. Okay guys, I'm completely focused on our task, and have come to the conclusion that we are royally screwed.
• Did You Just Flip Off Cthulhu?: In Act IV chapter 16, he's 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!!
• Fallen Angel: His Backstory reveals that he fell from grace as part of an agreement with his superiors to prove that not all monsters are bad.
• Female Angel, Male Demon: Inverted; he's a male angel whereas Kurumu is a succubus.
• Glowing Eyes of Doom/Power Glows: Both his eyes and wings glow when he uses his powers.
• Hair of Gold, Heart of Gold: He's a blonde-haired Nice Guy.
• Lethal Chef: In cooking class, he 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.
• Locked Out of the Loop: He was unaware that there was more than one Holy Lock, and is not happy to discover that his fellow angels had been watching Luna all along and knew that she was a monster before he met her.
• Love at First Sight: He's attracted to Kurumu from the minute he sees her.
• Magic Pants: Averted; his wings are too bulky to just phase through his shirts like Kurumu's, so he often shreds his shirts when he forms them.
• Nice Guy: He's always smiling and gets along with just about everyone.
• No Good Deed Goes Unpunished: In his backstory, he 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 have him executed and be done with it.
• Non-Uniform Uniform: Wears generic street clothes instead of the Yokai Academy uniform.
• Rage Against the Heavens: Goes off on one in Act IV chapter 16 when Luna and Falla are taken captive by the angels because their chrono magic is dangerous, and personally goes to the Heavens to take them back. It becomes an actual rage when he discovers that the Almighty and the angels are fully aware of Hokuto's plan to destroy the world, but will not/cannot do anything about it because Hokuto Was Once a Man; thus, he's still considered a human by the Heavens and they can't do anything to stop him. This leads Rason to call out the Almighty himself for his biases and viewpoints.
• Rage Breaking Point: Hits it in Act IV chapter 16 when he discovers that the Almighty and the other angels are fully aware of Hokuto's plan to revive Alucard, but cannot/will not do anything to stop him because, having been born human, Hokuto is still considered sacred and untouchable to the heavens until he actually dies with sin; the revelation that his Lord is going to forsake all life on Earth because of his laws completely pushes Rason over the edge.
• Running Gag: Virtually every time he comments on Apoch and Astreal's tendency to Speak in Unison, everyone just dismisses it. In Act VI, when Render, Leon, and Complica ask them how they keep doing it, Rason is actually relieved that someone else finally notices it.
• Screw the Rules, I'm Doing What's Right!: Even though he was banished from Heaven for killing a human in defense of a monster, Rason makes it clear time and time again that he doesn't regret doing so because he knows that not all monsters are evil.
• Underestimating Badassery: In Act III chapter 42, during the fight with Kuyou, he remarks that the fight isn't too hard, but Moka and Kurumu quickly inform him that the only reason they've been doing so well is because Kuyou hasn't even been trying yet. Right on cue, Kuyou goes One-Winged Angel and beats them all down.
• What Measure Is a Non-Human?: He once saved a female monster from a male human, and is now out to prove to his superiors that monsters can be good and humans are not always the victim.
• Zombie Advocate: He's determined to prove to his fellow angels that not all monsters are evil. By Act IV, he's finally succeeded.

Dark Kuyumaya

A shadow demon who enrolls in Yokai Academy alongside Rason, becoming friends with Tsukune and co. and romantically involved with Mizore.

• The Ace: He was Fairy Tale's top agent and is a Multi-Melee Master, expert with firearms, and operating computers and vehicles.
• Affectionate Nickname: He often calls Mizore his "little snow bunny."
• Always Save the Girl: Mizore is his 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.
• And I Must Scream: Unlike Rason, he is fully conscious and aware of his actions while being controlled by Ghaldin.
• Anti-Hero: 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.
• The Atoner: Ever since Arial freed him, he's spent his life honoring her and trying to atone for his past killings.
• Ax-Crazy: While Dark is generally composed and calm, he can dip into this when suitably enraged. If he should ever reach that point, don't expect the offending party's corpse to look pretty by the time he's through. A prime example is with Miyabi Fujisaki, who took Mizore's virginity and gloated about it to Dark's face during Act II; Dark's subsequent killing of Miyabi^note He, in this order, crushed the bones in Miyabi's arms and legs to powder before ripping said arms and legs clean off, punched him in the face so hard that his jawbone snapped clean off, and finally ripped his spinal cord out, all with his bare hands is so over-the-top that despite agreeing that Miyabi deserved every second of it, Tsukune and co. are still genuinely horrified at his brutality.
• Back from the Dead: At the end of Act II, he's murdered by Tsukune's ghoul form, but is re-summoned by Ahakon during Act III. Near the end, he is killed during the assault on Kiria's stronghold, but resurrected when Tsukune and Luna use the Chrono Displacement spell.
• Badass Biker: He owns and uses a motorcycle to great effect in Act IV.
• Bare-Handed Blade Block: In Act III chapter 41, he pulls one off on Kuyou, breaking the sword with his bare hands in the process.
• Berserk Button: Hurting or otherwise mistreating women in front of him in any way is essentially suicide.
• Beware the Quiet Ones: He's very much The Stoic, typically keeping to himself, listening to music, and rarely speaking. This, however, doesn't stop him from hospitalizing a few bullies or going One-Man Army on a Fairy Tale squadron.
• Black Eyes of Evil: Not exactly evil, but his eyes do turn black when he uses his powers.
• Broke Your Arm Punching Out Cthulhu: In Act III chapter 47, he 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 Pedestal/Rebuilt Pedestal: He always lived his life in honor of Arial, who granted him his freedom before she died. 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 after Arial kisses him, believing that everything he had fought for in Arial's name was meaningless. However, after Arial realizes the damage she has caused and accepts her role as Dark's guardian angel, they rebuild the pedestal.
• Bully Hunter: He's put several Yokai Academy bullies in the infirmary.
• Catchphrase: "I despise those who don't treat women right."
• Combat Pragmatist: One of his favorite tactics is to turn invisible and perform stealth kills.
• The Comically Serious: Constantly deadpan and has a blank expression on his face, but nonetheless has quite a few humorous scenes. For example, in Act IV chapter 29, when Akua is going crazy from Tsukune's aura and is dry-humping him in a public street, Dark's only reaction to it is a completely deadpan "Well, this is awkward."
• Dark and Troubled Past: He was summoned in the past by an Evil Sorcerer who forced him to kill numerous innocents. The final straw was when he was forced to murder an innocent child. Not only that, but he was also once Fairy Tale's top agent, though he was unaware of their true nature for a while, and turned on them when he did find out.
• Dark Is Not Evil: He's a Made of Evil demon with shadow-based powers, but is one of Tsukune's pals and a heroic, if tragic, character.
• Deadpan Snarker: More deadpan than snarker, but he fits.
  Ceal: You're a tough guy, aren't you?
  Dark: You're an asshole, aren't you.
• Death Amnesia: 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.
• Defector from Decadence: He was once one of Fairy Tale's top agents, but when he discovered their anti-human agenda, he promptly turned on them.
• Desperately Looking for a Purpose in Life: In a flashback in Act II to when Kiria first recruited him into Fairy Tale, Dark was doing nothing but rescuing girls from rapists and thugs and openly wondering if that was all he could do with his life. After discovering Fairy Tale's true nature, he has found one: being a good soul and helping people.
• Disproportionate Retribution: On two different occasions, he retaliates against bullies in shop class with power tools, cutting one with a power saw and using a belt sander on another's face.
• Don't Make Me Destroy You: After his brief fight with Ceal in Act VI chapter 45, he says a variation of this to Ceal:
  Dark: This fight is over. Don't make me make Complica and Falla cry by killing you just to prove my point.
• The Dragon: While a member of Fairy Tale, he was second in authority only to Kiria.
• Dull Surprise: 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."
• Embarrassing Nickname: When Ahakon resummons him in Act III, he dubs him "Amazing Joe." As soon as Dark regains his memories, he immediately threatens to rip Ahakon's spine out if he calls him that again.
• Extreme Doormat: Has become as such to Arial in Act VI, unable to say no to anything Arial says or does, even at the cost of his relationship with Mizore.
• Extreme Mêlée Revenge: When he discovers that Miyabi raped Mizore during Act II, he 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.
• 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.
• Genius Bruiser: He's got Super-Strength and can shrug off a lot of damage and give just as much, and while not a super-genius, he's intelligent enough to operate and hack computers, and expertly operate vehicles such as helicopters.
• Gonna Need More X: On two different occasions, after shooting a powerful monster to no ill effect, he deadpans that he "needs a bigger gun."
• Good Is Not Nice: He kills and injures with zero hesitation. Also, in Act IV chapter 13, his way of getting the new Apoch to understand that he's not the Dark who was her boyfriend is by bluntly telling her that she's a single-minded idiot who isn't worthy of his mark.
• Headphones Equal Isolation: He listens to an MP3 player to the extent that he largely communicates through lip reading.
• Hero Stole My Bike: In Act IV chapter 26, he steals Razico's bike in order to chase down Hokuto's airship.
• Heroes Prefer Swords: As revealed in a flashback in Act IV chapter 29, 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.
• Hidden Heart of Gold: 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.
• 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 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 him and Mizore or else Dark will kill him on the spot. In the next chapter, when Tsukune approaches them, hoping to talk things over, Dark is done talking and promptly attacks him:
  Dark: I told you to stay away. But you just don't listen.
• 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.
• Ignorant Minion: After his initial escape from his master, Dark was recruited by Kiria into Fairy Tale, who claimed he could be a hero to the world by joining them, quickly becoming their top agent. However, Dark was completely unaware of Fairy Tale's true motives until he discovered they planned to destroy Yokai Academy for teaching human/monster coexistence; outraged at being used, Dark erased all data related to Yokai Academy from Fairy Tale's computers and destroyed the base he was stationed at before taking his leave.
• Immune to Bullets: In Act III chapter 49, after being infected with Blackheart, he shrugs off a shotgun blast to the face.
• Invisibility: One of his powers; he can make himself invisible and extend the invisibility to a group of his choosing. It doesn't work on thermal equipment, however, and particularly powerful beings, such as Tsukune and Hokuto, can see him either way.
• Jerk with a Heart of Gold: Has shades of this; it's noted in Act III that he can barely get through shop class without subjecting a bully to one of the power tools, and, due to his stoicness, tends to come across as cold and uncaring. Despite this, he's a good person and a perfect gentleman.
• Jerkass Has a Point: Two big examples:
  • 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; since he had already trusted Tsukune before to keep the ghoul contained only for Tsukune to fail, why should he trust him to do so again?
  • In Act IV chapters 2 and 3, while everyone else is spending their time lambasting the Reformed, but Rejected Akua and Kahlua and outright asking why they should forgive them for their crimes under Fairy Tale, Dark is quick to remind them that he was a member of Fairy Tale once as well, and if they can forgive and accept him for his actions back then, then they should at least give Akua and Kahlua a fair chance; when Kurumu points out that Dark never went as far as to try to destroy the world like Kahlua and Akua did, Dark then reminds them that he was forced to kill an innocent child, which is just as bad.
    Inner Moka: I hate it when he makes a point like that.
• Just Following Orders: Subverted; he acknowledges that he was just following orders from his master when he killed those people, but explicitly states that it doesn't excuse his actions.
• Katanas Are Just Better: According to Mizore in Act VI chapter 15, a katana is his favorite weapon.
• Lightning Bruiser: He's very fast and agile, strong enough to crush one of Yukari's washtubs into a compact ball, and able to tolerate a lot of pain and injury.
• Locked Out of the Loop: When he joined 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.
• Made of Evil: As a shadow demon, he is stated to be composed solely of hatred and evil.
• Made of Iron: He's able to take such things as being impaled by Sinister Scythes, having his blood drained by a crazed Tsukune, and having his fingers broken and his leg shredded by Ceal, and keep on going like nothing happened. He writes it off as a high pain tolerance.
• Magnetic Hero: Of a sort. When he defected from Fairy Tale, several other people realized just how bad the organization was and followed his example, with Kenzo Shikazan's group in particular idolizing him.
• Meaningful Name: He took on the surname Kuyumaya in honor of Arial Kuyumaya, the little snow girl he was forced to kill who not only forgave him, but granted him his freedom with her last breaths, whereas his first name is taken from something Arial said to him ("I don't hate you, even if you are dark.").
• Momma's Boy: He's 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.
• Moral Myopia: He suffers from this to an extent. For example, in Act III chapter 8, after being resurrected/resummoned after Tsukune's inner ghoul killed him, he tries to murder Tsukune outright because of the ghoul, knowing full well that in killing Tsukune, he'd be doing the exact same thing to Moka that the ghoul did to Mizore by killing someone she loves. Furthermore, in Act VI, when Arial nearly kills Mizore in a psychotic rage, Dark comes up with lame excuses to justify Arial's behavior, when he had previously killed people just for looking at Mizore the wrong way; however, the situation with Arial can be justified, since she's his guardian angel and Dark just cannot live with forsaking her.
• 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.
• No-Sell: He's immune to Luna and Falla's fear-inducing powder because he's made of fear itself. In Act III chapter 5, he also does this to a blast of necro magic.
• Non-Uniform Uniform: Wears generic street clothes instead of the Yokai Academy uniform.
• One-Man Army: His Big Damn Heroes moment in Act II chapter 22 consists of him taking down an entire Fairy Tale squadron all by himself.
• Pay Evil unto Evil: In Act II, his murder of Miyabi Fujisaki is ridiculously over the top and brutal, but considering the fact that Miyabi enslaved Mizore's hometown, extorted Mizore for sex in exchange for sparing her mother's life before ordering Tsurara's execution anyway, and openly gloated about raping Mizore to Tsukune and co.'s faces, it's hard to feel any sympathy for him; despite being horrified at Dark's brutality, Tsukune and the others unanimously agree that Miyabi deserved every second of it. Kurumu sums it up best:
  Kurumu: Pay the price, you asshole!
• Personality Powers: He's a shadow demon and bears shadow-based powers such as invisibility; as such, he's stoic and rarely shaken by anything.
• Please Kill Me if It Satisfies You: When he meets Mizore's mother Tsurara in Act II, he promptly offers his life to her in penance for the snow women he killed under orders years before. After a moment, Tsurara lets him live.
• Pummeling the Corpse: When he snaps out of Ghaldin's mind control, his immediate reaction is to make his way over to the wizard's corpse and stomp his skull into bloody chunks.
• Race Fetish: Invoked; in Act II chapter 22, Rason jokes that, given that it was a yuki-onna who freed him from servitude and that he fell in love with Mizore, Dark has "a type."
• Selective Enforcement: Throughout Act VI, after discovering Arial's Jerk with a Heart of Gold nature and reconciling with her, Dark more or less sits back and does nothing while she repeatedly attacks Mizore, both physically and verbally, in response to Mizore trying to win her approval and make peace with her. While this case is somewhat justified, since Arial is his guardian angel and Dark needs her approval to live, it doesn't change the fact that he lets Arial get away with it when in the previous five acts, he had, at the very least, put numerous other people in the hospital for merely looking at Mizore the wrong way.
• Sex God: When he and Mizore consummate their relationship in Act II, Mizore describes the experience as so mind-blowing that she actually passed out from the pleasure more than once.
• The Stoic: He's nearly always cool, calm, and collected, shows little emotion, and is typically seen with a blank expression on his face.
  • Not So Stoic: If Mizore is in danger, however, he drops his calm demeanor, and if that happens, the person who pissed him off is doomed.
• Super-Strength: Demonstrated perfectly in Act I chapter 22, in which he easily crushes one of Yukari's washtubs into a ball with his bare hands.
• Turned Against Their Masters: As stated above, he turned on his former master and killed him after said master forced him to kill an innocent child.
• Violence Really Is the Answer: In Act III chapter 7, he explicitly warns Tsukune that he will kill him should Tsukune go anywhere near Mizore, making no secret of the fact that he doesn't trust Tsukune, even with the Holy Lock, to hold the ghoul back when he failed to do so once already. By the next chapter, Tsukune approaches them anyway, hoping to talk things over... and Dark promptly attacks him at full force, telling Tsukune that he should have just heeded his warnings and stayed away. However, in the ensuing fight, Dark, along with Mizore and Felucia, who both agreed with him that the Holy Lock was untrustworthy, see firsthand just how strong the chain is and accept that the ghoul is gone.
• Wife-Basher Basher: Harming or otherwise mistreating women around him is a very bad idea.
  Dark: I despise those who don't treat women right.
• Would Hit a Girl: He may be a Wife-Basher Basher, but Dark has no qualms against throwing down with female villains, as well as nonchalantly blasting Felucia's head off with a shotgun. Since Felucia can simply regenerate and the female villains are, well, villains, it's probably justified.
• 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 either of them.

Arial Kuyumaya

A little snow girl whom Dark was forced to kill by his former master some time before the events of the fic. She serves as a guardian angel figure to Dark, and comes Back from the Dead in a sense during Act V.

• A-Cup Angst: In Act V chapter 19, she 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.
• Ax-Crazy: She often comes across as this in Act VI, in part due to her Hair-Trigger Temper and 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; by the end, Mizore is so horrifically injured that Ceal has to transfer organic matter from deceased HDA officers in order to heal her. The others even outright describe her as insane on more than one occasion. It gets to the point that in chapter 46, when Arial slashes Kokoa across the arm for injuring Sun, Gabriel outright says that Kokoa should consider herself lucky that that's all Arial did.
• Back from the Dead/Undead Child: In Act V, she escapes from Heaven to Earth via a rift, though she's still technically dead.
• Berserk Button: Mentioning her Hair-Trigger Temper in front of her is a surefire way to get her to lose said temper.
• Because You Were Nice to Me: Part of the reason she became infatuated with Dark; she witnessed him kill his former master after said master forced him to kill her.
• Bratty Half-Pint: As shown throughout Acts V and VI, she's stubborn, has a very short temper, and is a big-time Jerkass, especially to Mizore.
• Can't Take Criticism: Fitting her extreme stubbornness, Arial hates being called out on her Jerkass behavior or Hair-Trigger Temper, responding with extreme annoyance at best and physical violence at worst. For example, in Act VI chapter 44, after Mizore tells her that she's going to end up driving away all of her friends due to her temper, Arial responds by nailing Mizore in the forehead with an ice shard and screaming at her to "do them all a favor" and shut up.
• Characterization Marches On: In her initial appearance during Dark's Origin Story in Act I, Arial seemed to be an innocent and kind little girl. Come Acts V and VI, and it turns out she's a stubborn, near-psychotic Bratty Half-Pint.
• Children Are Innocent: To the extent that being forced to kill her was what led to Dark turning on his master.
• Cute and Psycho: She's a cute little snow girl... with a Hair-Trigger Temper who will, at the very least, try to physically attack those who anger her.
• Death by Origin Story: She was killed by Dark, which prompted him to turn against his master.
• Dirty Kid: She shows such tendencies in Acts V and VI. She dreams of marrying Dark in Act V chapter 23, wakes up having been making out with a pillow in her sleep, and remarks that it's a good thing Sun woke her up "before the honeymoon." In the penultimate chapter of Act VI, she nonchalantly mentions having watched pornography in Heaven.
• Enfant Terrible: She's a cute little snow girl... with a Hair-Trigger Temper that borders on Ax-Crazy and a penchant for extreme violence when provoked. At least once, Moka and the others have pondered how Arial was accepted into Heaven in the first place.
• 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 final chapter of Act VI, she has agreed to give Mizore a chance, if only because it was Complica's Last Request.
• Entitled Bastard: From chapter 27 of Act VI onwards, when Arial Kuyumaya accepts her role as Dark's guardian angel/mother figure and nothing more after spending most of her screentime being an Ax-Crazy Yandere over him, she becomes this to Mizore, demanding that Mizore actually shows her respect before she even considers giving her her blessing to marry Dark; considering the fact that Arial had previously savagely clawed Mizore into Ludicrous Gibs in a jealous rage^note Mizore was subsequently healed by Ceal, stole her engagement ring right off of her hand while issuing death threats in the middle of the night, and is continuing to be nothing but a Jerkass to her despite all of Mizore's attempts to bond with her, and even after Mizore saved her ungrateful life, it's been pointed out at least once that Arial has done nothing to deserve respect from Mizore.
• Entitled to Have You: Her 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.
• Face Death with Dignity: As shown in Dark's flashback, she calmly accepted her fate when Dark's original master ordered him to kill her, gently reassuring him that it wasn't his fault and that she didn't hate him.
• Fatal Flaw: Her stubbornness and temper.
• The Friend Nobody Likes: She has a Hair-Trigger Temper and constantly acts like a Spoiled Brat, with every attempt to berate her and get her to mellow out falling flat because she Can't Take Criticism and will physically attack anyone who tries. Throughout Act VI, only Dark, Complica, and Sun can actually stand to be around her; everyone else in the group barely tolerates her at best and has no qualms against calling her crazy, stupid, or otherwise badmouthing her to her face.
• Friendless Background: In Act VI chapter 17, Gabriel mentions that Arial had trouble making any friends due to her temper.
• Good Is Not Nice: Is a fundamentally good person, but has an explosive temper and is perfectly willing and able to resort to extreme violence.
• Hair-Trigger Temper: Let's just say she has a pretty short fuse.
• Hate Sink: A rare heroic example; though she's shown in-universe to be a Jerk with a Heart of Gold, her more Jerkass qualities, such as her bitchiness towards Mizore and her dangerous temper, tend to outshine her redeeming aspects and can cost her the sympathy of many.
• Headphones Equal Isolation: She listens to an MP3 player on a regular basis. It's revealed in Act VI chapter 17 that she was never very friendly with anyone, and out of frustration that she could never find a boy to like or a potential husband, and turned to her music all day every day to tune the "harsh world" around her out.
• Hypocrite: In Act VI chapter 20, she criticizes Ran for chasing after Ahakon and refusing to accept him as taken, when she herself is/was doing the exact same thing with Dark. She also has the nerve to call Kokoa out over her Hair-Trigger Temper when her own temper is just as bad, if not worse. Furthermore, even after accepting that Gin loves Kokoa and not Sun and helping the latter understand that, she still can't accept that Dark loves Mizore.
• I Resemble That Remark!: Every time Arial is called out on her Hair-Trigger Temper, her general response is to snap and angrily order whoever mentioned it to shut up, and that's if she doesn't just straight up physically assault them.
• Ignored Epiphany: For several chapters after Act VI chapter 18,she 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.
• It's All About Me: Even after accepting her role as Dark's guardian angel/mother figure, this is one of her most defining traits; she constantly claims that she's looking out for Dark's best interests by trying to choose who he gets to marry, but it's obvious to anyone who's paying attention that she only cares about what she wants for him.
• Jerkass to One: Arial is a Jerk with a Heart of Gold, and tends to be snippy and bitchy to everyone save for Dark, Felucia, Sun, and Complica. She's especially a Jerkass to Mizore, constantly insulting her and being rude even when Mizore is trying to be nice; it reaches the point where Arial completely blows it off when Mizore saves her life.
• Jerk with a Heart of Gold: She 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, even actively resisting Mizore's attempts to prove herself and make peace with her. She's firmly convinced that Felucia would be a far better choice for Dark... and even then, she plans to deny Felucia the chance to go to Heaven, instead wanting her to stay with Dark until he himself dies. Nonetheless, she's a fundamentally good person, having been one of the very first monsters to be accepted into Heaven, and her Pet the Dog moments prove it.
• Jerk with a Heart of Jerk: Arial often dips into this towards Mizore throughout Act VI. There's a particular moment in chapter 42, where she has an initial moment of bonding with Mizore, talking about how Dark was when she first saw him... and then goes right back to badmouthing and dissing Mizore, giving her a brutal "The Reason You Suck" Speech about how she considers her not worthy of Dark.
• Laser-Guided Karma:
  • She nearly kills Mizore in a psychotic rage during Act VI chapters 7 and 8. In chapter 17, during their fight, Mizore snaps and beats her into the ground right back.
  • She spends all of Act VI belittling Mizore and treating her like dirt, even as Mizore is trying to be nice to her and befriend her. It climaxes in 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... and when Mizore hits the ball, Arial gets struck in the head by it; Mizore swears up and down that it was an accident, but both Leon and Astreal believe otherwise.
• Lethally Stupid: Throughout most Act VI, due to her single-minded obsession with Dark. As a direct result of said obsession, as well as her blatant refusal to accept that Dark doesn't love her like that, she causes the group a lot of unnecessary trouble, culminating in her driving Dark to a nervous breakdown and causing him to get near-fatally hit by a car.
• The Load: 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.
• Loving a Shadow: In Acts V and VI. She's obsessed with Dark, but as revealed in Act VI chapter 16, she literally knows nothing about him.
• Moral Myopia: 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 done absolutely nothing to deserve any respect from Mizore.
• Murder the Hypotenuse: In Act VI, she 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.
• Never My Fault: In Act VI chapter 27, she 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 Arial because she nearly killed Mizore in a jealous rage less than twenty-four hours ago.
• No-Holds-Barred Beatdown: In Act VI chapters 7 and 8, she dishes out an absolutely savage one to Mizore upon finding out that the latter is Dark's girlfriend, using her ice claws to literally tear Mizore apart. By the time she's done, Mizore has been shredded into Ludicrous Gibs and cannot speak coherently, forcing Ceal to reconstruct her body using the corpse of an HDA soldier to save her life, and Arial is only stopped from going any further by being knocked out by Razico.
• Not Helping Your Case: She has a bad temper, and losing it whenever someone brings it up certainly doesn't help.
• Oblivious to His Own Description: Throughout Act VI, Arial does such things as chewing Kokoa out for her Hair-Trigger Temper, chewing Ran out for chasing after Ahakon romantically when he's already dating Yukari and doesn't love her like that, and telling Sun that she has to accept that Gin has moved on to Kokoa and move on... when, as shown throughout this act and the previous one, a Hair-Trigger Temper and issues with her loved ones choosing other girls to be with instead of her are two of the traits that define Arial most as a person. Anyone who tries to point this out to her runs the risk of setting off her Berserk Button and getting physically attacked.
• Odd Friendship: With Complica. The only thing the two really have in common is that they're monster children who died, and they have near polar opposite personalities. Complica is a calm and sweet Nice Girl, while Arial is a stubborn and immature Jerk with a Heart of Gold with a Hair-Trigger Temper that borders on Ax-Crazy. That being said, the two do get along very well, with Arial even agreeing to give Mizore a fair chance to prove herself worthy of Dark because Complica begged her to do so on her deathbed.
• O.O.C. Is Serious Business: Invoked in Act VII chapter 1. Arial spent most of the previous act being a complete Jerkass to Mizore, right up to not caring that Mizore saved her from a Burning with Anger Kokoa. So when Mizore makes an effort to comfort her over Complica's death/ascension to anomaly and reassures her that they will see her again, both she and Felucia are completely floored when Arial stops just long enough to genuinely thank Mizore for doing so before leaving the room; Felucia even feigns chills and wonders aloud if Hell just froze over.
• Our Angels Are Different: She's a snow angel, described in the fic as essentially being a dead yuki-onna.
• Pet the Dog: Arial is every bit a Bratty Half-Pint with a Hair-Trigger Temper, but at different points, she proves that she does have a good heart beneath it all:
  • Her final act before she died. Despite the fact that Dark mortally wounded her, when he turns on his master and slaughtered him in a rage at being forced to kill her, Arial forgave him for doing so, told him it wasn't his fault, took the bracelet that his summoner used to control him, thus becoming his new master, and granted him his freedom with her last breaths.
  • In Act V chapter 23, she voluntarily passes up an opportunity to go straight to Yokai Academy, instead choosing to help Marin save her floundering inn.
  • In Act VI chapter 46, she listens to Kokoa's story about her love life with Gin, and is visibly concerned when she finds out what Nagare Kano did to her and the other girls.
  • She's mistreated Mizore and gone out of her way to be a bitch to her throughout Act VI, but in the penultimate chapter, agrees to give her a fair chance as per the Last Request of Complica, her closest friend. It's shown perfectly in the first chapter of Act VII; while still snippy and bitchy toward Mizore at first, when Mizore makes an effort to comfort her over Complica's disappearance/ascension to anomaly, Arial is moved and gives her a genuine thank you for doing so before leaving the room. It's the first time Arial has ever done or said anything remotely nice to Mizore since they've met.
• "The Reason You Suck" Speech: In Act VI chapter 42, after a brief moment of bonding, Arial goes right back to badmouthing Mizore right out of the blue with one of these, beating into her that as far as she's concerned, Mizore will never be worthy of Dark.
• Screw Your Ultimatum!: In her stubbornness, she 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 tried to kill Mizore the other day and 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.
• Selective Obliviousness: Taken up to eleven. Throughout all of Act V and the first third or so of Act VI, Arial is infatuated with Dark and, no matter how many times it's explicitly pointed out to her that he doesn't love her that way, blindly refuses to accept it until Act VI chapter 27, in which her actions cause Dark to have a mental breakdown that nearly leads to his death; in Ruby's words, not even she and the other members of Tsukune's Unwanted Harem were as stupid and blind over Tsukune as Arial was with Dark.
• Shipper on Deck: In Act VI, she openly favors having Felucia marry Dark over Mizore, completely uncaring about the three's feelings on the subject.
• Spoiled Brat: She has shades of this, constantly throwing destructive temper tantrums when she hears criticism or doesn't get her way, as well as openly expecting Mizore to respect her despite being a Jerkass who tried to murder her in a jealous rage. In Act VI chapter 15, Moka tells her point-blank that she's "horrible and rotten."
• Stubborn Mule: Throughout Acts V and VI, she 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.
• Surprisingly Realistic Outcome: Arial has spent all of her afterlife, as well as all of Act V and most of Act VI, infatuated with Dark because he turned on his master in a rage after being forced to kill her. It isn't until chapter 27, when the reveal of her Yandere nature toward him leads him to have a nervous breakdown and nearly die, that Arial is finally forced to acknowledge that her purpose is to serve as Dark's guardian angel/mother figure and nothing more... which leads to her declaring that Mizore has no right to Dark and must actually prove herself worthy before she can actually marry her, and eventually dropping that completely and deciding that Felucia would be a better match for him. In chapter 50, after Dark tells her that he'll fly a helicopter next time and "take her for a ride she'll really remember," Arial's Inner Monologue reveals that despite her acceptance that she and Dark will never be involved romantically, her feelings haven't just magically gone away and are still lingering, which helps to explain her ongoing hostility toward Mizore.
• Took a Level in Kindness: As of the first chapter of Act VII. While she's at first her usual bitchy self to Mizore, after Mizore comforts her over Complica and reassures her that they'll see her again, Arial is moved and genuinely thanks her, much to Mizore and Felucia's surprise.
• Troubling Unchildlike Behavior: Aside from her Yandere fixation on Dark, in Act VI chapter 13, she broke into Mizore's bedroom in the middle of the night to threaten her with death should she not stay away from Dark.
• Turn the Other Cheek: When Dark mortally wounded her, she not only forgave him, knowing it wasn't his fault and he was being controlled, but she took the bracelet that his summoner used to control him, thus becoming his new master, and granted him his freedom with her last breaths.
• Ungrateful Bitch:
  • In Act VI chapter 42, Mizore saves her from being killed by an enraged Kokoa, who has unleashed her overcharge. Arial scornfully remarks that all Mizore really did was push her away 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 over the head with a shard of ice.
  • In Act VI chapter 44, she gets into the act again, disparaging Ceal for his pride and calling Mizore out for defending "that asshole" even though he's going out to retrieve a spell that will heal Sun's brain damage and restore her fractured mind. That being said, two chapters later, Arial solemnly admits that she'll take her words back if Ceal succeeds in saving Sun.
  • Averted come Act VII chapter 1; while it initially seems that she's ungrateful for Mizore's attempt to comfort her over Complica's passing, before she leaves the room, Arial pauses just long enough to give her a genuine thank you.
• Unskilled, but Strong: When she comes to Earth from Heaven in Acts V and VI, she's 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.
• 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.

Apoch and Astreal Ezrana

Twin summoned beings/witches who arrive at Yokai Academy while fleeing from their abusive master Ghaldin Rayazo. After Tsukune and his friends help them by killing Ghaldin, they become friends with the group.

• Always Identical Twins: They're identical except their hair and eye colors. Apoch has short black hair and yellow eyes, whereas Astreal has long blond hair and black eyes.
• And I Must Scream: As summoned beings, they're still fully conscious of their actions while under the effects of mind control spells.
• And Then What?: After Moka kills Ghaldin, thus freeing them, they admit that they never really thought about what they would do after being granted their freedom. Ruby solves the problem by making them her assistants.
• Angelic Beauty: When Ahakon first sees them, he reflects that they're beautiful like angels.
• Artificial Human/Pure Magic Being: They're summoned beings created by magic. As a result, they're more in tune with their own magic than most other witches and, unlike Yukari, can use their powers without a wand.
• Be Careful What You Wish For: In Act III chapter 40, 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.
• Beware the Nice Ones: They're noted on multiple occasions to be quite pleasant and polite. That being said, when their patience is at an end, they have no qualms against blowing someone up.
• Big Sister Instinct: Astreal is very protective of Apoch.
• Boyish Short Hair: Apoch wears her hair this way.
• Can't Take Criticism: In Act III chapter 23, the girls of the group call them out for their uncharacteristically harsh treatment of Yukari, stating that they can't just act like that. Apoch and Astreal's response? They scream at the others not to tell them what to do, and then blow up Felucia with little-to-no provocation before lying to Ms. Nekonome to get the girls kicked out of class.
• Clingy Jealous Girl: They become this towards Ahakon during Act III, treating Yukari badly as a result.
• Clone Army: In Act II, Fairy Tale gets a hold of their original summoning spell and uses it to create a literal army of Apochs and Astreals for them to use in weapon testing, combat, and even as sex toys.
• Complexity Addiction: During the early parts of Act I, they 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.
• "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, the two apologize for the trouble and insist that they only wanted help, to which Tsukune points out that the entire group would have helped them willingly if they had just asked and allowed them to act on their own accord.
• Dead Alternate Counterpart: The Apoch and Astreal who appear in Act IV onwards are different versions of them from an Alternate Timeline; the originals were killed by Jovian and Kuyou, respectively.
• Death Is Cheap: Whether from being summoned again or being called from an Alternate Timeline, these girls just can't stay dead.
• Disproportionate Retribution: In Act III chapter 23, when the girls confront Apoch and Astreal over their mistreatment of Yukari, they respond by blowing up Felucia and then lying to Ms. Nekonome by stating that the girls themselves were causing trouble, getting them sent to the headmaster's office.
• 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.
• Eek, a Mouse!!: In Act I chapter 25, Apoch freaks out at the sight of a bug, much to Astreal's annoyance.
• Energy Bow: In Act VI, Astreal gets this through the Artimus Arrow spell.
• Forgot About His Powers: In Act III chapter 13, they 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.
• Hand Blast/Power Palms: Astreal's primary power is projecting red energy beams from her hands.
• 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, since they're controlling the boys to fight for them against their will, 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.
• Hypocrite: In Act III chapter 23, they state that part of the reason they refuse to let Yukari near Ahakon is because she "never learns and chases after those who are taken." In the next chapter, their jerkish actions towards Yukari lead Ahakon to break up with them; for the rest of the fic, they themselves chase after Ahakon even though he loves Yukari and even try to steal him from her.
• I Just Want to Be Free: Their primary motivation upon coming to Yokai is to find a way to be free of their master. Thanks to Moka, they get it.
• Inept Mage: As shown in Act I chapter 12, they're 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.
• Informed Ability: They're noted to be "the perfect shield and the perfect sword," with unbreakable shields and unblockable energy blasts. From Act II onwards, more and more characters prove to be strong enough to effortlessly break their shields and survive their shots point-blank, making them anything but perfect.
• Irony: In Act III chapters 23 and 24, the two of them outright try to kill Yukari in an effort to prevent her from stealing Ahakon from them... and it's because they tried to kill her that Ahakon breaks up with them in favor of Yukari.
• Kill It with Fire: The original Astreal was burned alive by Kuyou during Act III.
• Laser Blade: From Act IV onwards, Apoch is able to form her force field into a super-sharp energy blade.
• Laser-Guided Karma: In Act III chapter 23, they, proving themselves to be Clingy Jealous Girls over Ahakon, spend the entire chapter acting like complete bitches to the other girls in the group, deliberately getting them kicked out of Ms. Nekonome's class and going so far as to try to murder Yukari, only failing in doing so thanks to Luna. Afterwards, Tsukune unleashes Inner Moka, who is anything but pleased at the Ezranas for their actions; cue Oh, Crap! from the witch sisters right before Inner Moka beats the shit out of them. In the next chapter, they end up picking another fight with Yukari, causing Ahakon to dump them in favor of Yukari, the very thing they had been trying to prevent.
• Love Makes You Crazy: The two become as such due to their attraction to Ahakon in Act III, especially come chapters 23 and 24. At first, they just become Clingy Jealous Girls and Take a Level in Jerkass, but this spirals into them outright trying to murder Yukari. Needless to say, Ahakon decides to dump them for how crazy they're acting, and also because he's also realized his own feelings for Yukari.
• Mistreatment-Induced Betrayal: The whole reason they ran away from Ghaldin in the first place is because they got sick of being abused by him. Similarly, the Clone Army Fairy Tale summons in Act II eventually got sick of the abuse and turned on them as well.
• Moral Myopia: In Act III chapter 24, when they 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. Inner Moka quickly points out that they have no room to talk, considering the fact that she only beat them up in the first place because they themselves tried to kill Yukari in a rage. Additionally, in Act III chapter 23, they remark that they distrust Yukari to be around Ahakon because she "never learns and chases after those who are taken," and when their actions cause Ahakon to break up with them in favor of Yukari, they themselves spend the rest of the fic chasing after Ahakon, who is now already taken, and even try to seduce him and steal him back at least once.
• Murder Is the Best Solution: Upon their resurrection in Act III, upon finding out that Kokoa was the one who turned Tsukune into a ghoul and thus indirectly responsible for their deaths, Astreal is quick to hold a grudge against Kokoa to the extent that she outright tries to shoot Kokoa dead right in front of everybody on multiple occasions; in Act III chapter 10 alone, she tries to do so three times in rapid succession, and is admonished by it by both Ruby and Apoch each time. In Act III chapter 12, when Apoch tries to talk the ghoul-infected Kokoa down, Astreal promptly jumps right to the notion of killing her.
• Murder the Hypotenuse: In Act III chapters 23 and 24, they try to kill Yukari right in front of everybody to keep her from taking Ahakon away. Both times they fail: the first thanks to Luna's intervention, and the second because Ahakon threw Yukari out of the way of their attack, only escaping death thanks to Luna. Needless to say, after the second time, Ahakon promptly dumps them in favor of Yukari right then and there.
• My God, What Have I Done?: In Act III chapter 24, they have this reaction when they seemingly kill Ahakon during their fight with Yukari; as a result, they're perfectly willing to let Yukari kill them in revenge until it's revealed that Luna saved Ahakon just in time.
• No Sympathy for Grudgeholders: In Act II, a blood transfusion from Kokoa turns Tsukune into a ghoul, and the first thing the ghoul does is murder Apoch and Astreal in cold blood. When the two are resurrected in Act III, Astreal, after discovering that Kokoa was the one who created the ghoul, albeit accidentally, tries to shoot Kokoa dead on more than one occasion, and is called out on it by the others every single time; even Apoch, who also blames Kokoa for their deaths, calls Astreal out.
• Not Helping Your Case: In Act III chapter 24, while explaining the reasons behind their Jerkass actions in the previous chapter, they insist that they didn't mean to be so cruel. Rrrright; they threaten the gang, blow up Felucia, lie to Ms. Nekonome to get the girls sent to the headmaster's office for simply asking them why they were mistreating Yukari, and try to kill Yukari right in front of God and everybody, and then say that they didn't mean to act like such bitches. So convincing.
• Oh, Crap!: In Act III chapter 23, this is Apoch and Astreal's completely understandable reaction after their failed Murder the Hypotenuse attempt on Yukari when Tsukune unleashes Inner Moka, who is anything but pleased with them for said attempt...
• Poor Communication Kills: 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.
• Self-Fulfilling Prophecy: As stated under Irony above, their attempts to prevent Ahakon from leaving them for Yukari end up causing him to do exactly that.
• Shrinking Violet: Apoch is explicitly described as the shy one.
• Sophisticated as Hell: From Act IV onwards, they will often exclaim "Please fucking die!" as a Pre-Mortem One-Liner.
• Speak in Unison: Part of their Verbal Tic. Rason is the only one who ever really remarks on it until Render, Leon, and Complica enter the picture.
• Supernatural Gold Eyes: Apoch possesses yellow eyes, and is a witch forged from magic itself.
• Swiss-Army Superpower: In Act IV, Apoch has learned to shape her barrier into a Laser Blade.
• Took a Level in Jerkass: In Act III chapter 23, Apoch and Astreal, having become Ahakon's girlfriends, act uncharacteristically bitchy towards Yukari and the others, believing that Yukari might try to steal Ahakon away; when the other girls try to talk things out with them, Apoch and Astreal actually threaten them, and then lie to Ms. Nekonome, claiming that Moka and the others were the ones causing trouble and getting them sent to the headmaster's office for no reason. Finally, after they outright try to kill Yukari in a jealous rage, karma catches up to them big time when Tsukune unleashes Inner Moka, who wastes no time in beating the shit out of Apoch and Astreal for their jerkassery.
• Turned Against Their Masters: They're first introduced fleeing from their master.
• Ungrateful Bitch: In Act III chapter 24, after they spent most of the previous chapter mistreating Yukari to the extent that they tried to murder her, Inner Moka outright accuses them as such considering the fact that Yukari was the one who got their summoning spell back from Fairy Tale; in short, the Ezranas are only alive right now thanks to Yukari, and they repay her by treating her like shit and trying to kill her.
• 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.
• Verbal Tic: They have a habit of addressing others as "Mr." or "Mrs." and talking in unison.
• The Worf Effect: They're constantly mentioned to be "the perfect shield and the perfect sword," with unbreakable shields and unblockable/unsurvivable energy blasts. From Act II onwards, they're often on the receiving end of this to showcase how strong the new villains are, starting with Ghoul!Tsukune, who effortlessly pierces through Apoch's shield with his bare hands and survives a massive blast that kills Astreal herself.

Felucia Sonsta

A doll demon who once worked for Fairy Tale and left around the same time Dark did.

• Affectionate Nickname: Often calls Mizore "slushy," initially as an insult, but when she's warmed up to Mizore, it becomes more affectionate.
• The Alcoholic: In a 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.
• Attention Deficit... Ooh, Shiny!: In a 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 her is that she's "a tramp who just barges in and demands all the attention from everybody around her."
• Back from the Dead: She's killed at the end of Act IV, but is brought back in Act VI, bound to a special soul band that keeps her alive.
• Brainwashed and Crazy: During Act IV, she is put under a spell by Jovian and Jacqueline that causes this; the spell is broken when the two are killed.
• Custom Uniform: While attending Yokai Academy, she wears the uniform, but does not wear a neck ribbon, leaves the jacket open, and wears a black plaid skirt rather than a brown one.
• Defector from Decadence: She's among the people who followed Dark's example and turned on Fairy Tale.
• Evil Is Petty: As revealed in a flashback in Act IV chapter 29, before her Heel–Face Turn, she once stole a car, nearly killing two human teens in the process, simply because it matched her eyes.
• Friend-or-Idol Decision: She faces one in Act IV, being forced to choose between helping Mizore escape Hokuto's crashing airship or retrieve her Soul Jar before it's destroyed. She chooses the former.
• Healing Factor: Goes hand-in-hand with Resurrective Immortality below.
• Hell-Bent for Leather: Constantly wears a leather jacket.
• Hopeless Suitor: She's infatuated with Dark, but he only has eyes for Mizore.
• I Want My Beloved to Be Happy: She ultimately accepts that Dark will only love Mizore and not her, and resigns herself to befriend Mizore to at least stay close to him. By the time of Act VI, she's actively shipping the two.
• Immortal Life Is Cheap: During virtually every fight she's involved in, she tends to get the worst of the combat damage; among other things, she's been shot in the head, impaled, burned to ash, blown up, and gotten her head cracked open by a baseball bat.
• 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 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.
• Moral Myopia: In Act III chapter 8, she actively fights Moka and Kokoa to prevent them from stopping Dark from killing Tsukune to prevent the ghoul from returning, uncaring that in doing so, she's doing the exact same thing the ghoul did to her and Mizore by killing someone she loves.
• Motor Mouth: According to Dark, the only way he's ever found out how to shut her up is by blowing her head off with a shotgun.
• Rape Leads to Insanity: 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.
• Refuse to Rescue the Disliked: After being blackmailed by Kano in 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 openly suggests to the others that they let Kuyou kill everyone.
  Felucia: These are the creeps we're protecting from Kuyou? Seriously?
• Refusing Paradise: Upon her death in Act IV, she is offered a place in Heaven for her actions, but declines, preferring to go to Hell to torture Jovian and Jacqueline as payback for them torturing, raping, and brainwashing her.
• Resurrective Immortality: Every time she's killed, she simply regenerates herself and gets back up again. First displayed when Dark gets tired of her babbling and blows her head off with a shotgun.
• Revenge Before Reason: Deliberately Refusing Paradise so you can personally punish your enemies in Hell is about as "Before Reason" as you can get. ^note Granted, Jovian and Jacqueline did torture her, rape her, and drive her insane. Indeed, she ends up exhausting her Roaring Rampage of Revenge and then agreeing to a Redemption Quest in order to go to Heaven after all.
• 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. She even goes so far as to refuse entry into Heaven to do so.
• Single-Target Sexuality: She never shows interest in anyone but Dark.
• Sir Swears-a-Lot: She's easily the most foul-mouthed member of the cast. Lampshaded in Act III chapter 23, after her brief confrontation with Apoch and Astreal over their mistreatment of Yukari:
  Felucia: I asked why the fuck are they being so fucking mean to their friend and acting like total bitches.
  Kurumu: Going to assume you used those exact words.
  Felucia: Well, duh.
• Soul Jar: As a doll demon, Felucia's essence is hidden in a special object, and she can only truly die if said object is destroyed. Fortunately for her, no one knows what her Soul Jar is or where she hid it, until Act III, where it's revealed to be a blue-and-green conch shell. Hokuto and the Kikion sisters manage to find and acquire it and use it to extort Felucia into helping them.
• Yank the Dog's Chain: In Act III chapters 38 and 39, she wins a date with Dark... only to be kidnapped by Hokuto and extorted into being his minion.

Ahakon Maradoza

A young mage who's entire village was destroyed by Fairy Tale. He joins Tsukune's group to get revenge. Initially attracted to the Ezrana sisters, he ultimately starts a romantic relationship with Yukari.

• Arbitrary Skepticism: Despite living in a world where monsters and demons are commonplace, he's genuinely surprised to see Kou, a talking bat.

• Child Mage: Not only is he the same age as Yukari, mage is in fact his species.
• Child Prodigy: Like Yukari, he's a pre-teen who's smart enough to enroll in high school.

• Elemental Powers: Often uses fire, water, and lightning magic.
• It's Personal: Fairy Tale destroyed his village and killed his family.
• KidAnova: In addition to Yukari, he's also managed to attract older girls like Ran Otonashi and the Ezrana twins.
• Mage Species: He's a mage. Mages are able to cast spells without wands, unlike witches, but have lower magical reserves and tire faster.
• Nice Job Breaking It, Hero: While fleeing from Fairy Tale, he accidentally leads them right to Mizore's hometown.
• Non-Uniform Uniform: Wears generic street clothes instead of the Yokai Academy uniform.
• Nothing Personal: In Act III chapter 7, he sides with Dark in wanting Tsukune dead; it's stated that he doesn't actually hate Tsukune, but is terrified at the thought of a ghoul resurfacing.
• Nosebleed: Gets one when he sees Apoch and Astreal wearing only towels in Act III chapter 9.
• Red Is Heroic: A good kid with red hair and who wears a red cape.
• Sole Survivor: Of Fairy Tale's attack on his village.
• That Came Out Wrong: In Act III chapter 23, Apoch and Astreal, having previously warned Yukari to stay away from Ahakon, are incensed to see her with him; Ahakon insists that it's Not What It Looks Like and that Yukari was "just trying to stop me from finding you two." He realizes just what that sounded like all too late to rectify it.
• Underestimating Badassery: Like Rason in Act III chapter 42, he underestimates Kuyou during the fight, outright calling him a joke. Moka and Kurumu quickly inform him that the only reason they've been doing so well is because Kuyou hasn't actually been trying, and right at that moment, Kuyou goes One-Winged Angel.

Luna Cii

A young female chronofly, a species of butterfly-winged monsters with power over time. It's later revealed that she was the female monster whom Rason saved from an evil human, and that she was a princess of a kingdom of chronoflies before that kingdom was destroyed.

• Attempted Rape: She was saved from a rape attempt by Rason in the past.
• Because You Were Nice to Me: She's obsessed with Rason because he saved her from an evil human.
• Butterfly of Doom: In Act III, when she 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.
• Broken Bird: In part due to her chrono dementia. When curing said dementia in Act VI chapter 37, Ceal outright states that her mind is so fractured that it's a miracle Luna can still walk and talk.
• Cain and Abel: The Abel to Falla's Cain, until the latter is killed and replaced by an Alternate Self.
• Crazy Sane: She has quite a few moments of clarity, and her bouts of chrono dementia are largely depicted as periods of Laughing Mad and Suddenly Shouting.
• Cute and Psycho: She's described as being just as curvy and attractive as Moka, but also suffers from chrono dementia.
• Desperately Craves Affection: In Act VI, she's so desperate for love that she latches onto Hex, unable to see anything wrong with him until he tells her point-blank that he would have left her in Babylon's captivity if she didn't have chrono magic.
• Extreme Omnivore: Among other things, she's eaten rocks, plates, and her own gym clothes.
• 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.
• Interspecies Adoption/Raised by Humans: 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.
• Last of Her Kind: Along with her sister Falla, she's the last living chronofly.
• Punny Name: Luna Cii = lunacy.
• Story-Breaker Power: Her chrono magic makes her among the most powerful in Tsukune's group. Naturally, the author keeps coming up with ways to keep her from going all out to prevent her from rendering everyone else useless, such as the Almighty's law forbidding her from actual Time Travel, the risk of chrono dementia, the risk of getting preyed upon by chrono wraiths, and Babylon keeping track of her chrono magic in order to capture her.
• Time Master: She has power over time.
• Winged Humanoid: Butterfly wings.

Falla Cii

Luna's sister, who, along with Luna herself, is the one of the last chronoflies.

Her original self in the mainstream timeline was directly responsible for the near-extinction of her species out of jealousy that Luna was to be crowned queen instead of her. However, in Act IV, she is killed and replaced by a far more sympathetic version of herself from an Alternate Timeline, during which she, not Moka, met Tsukune on his first day at Yokai Academy and began a relationship with him.

As it turns out, that version of Falla was in fact suffering from amnesia and was also responsible for the chronoflies' extinction in her time, which she remembers after coming into contact with Lilith's Mirror.

Both Fallas

• Eyepatch of Power: She lost her left eye to Luna originally and took to wearing a black eyepatch. Ceal later restores said eye... by tearing out the evil Falla's remaining eye and using it as a replacement.
• Good Eyes, Evil Eyes: While Luna and Complica has green eyes, Falla has red eyes. Played straight with the original dark Falla, but subverted with the good Falla.
• Psychopathic Manchild:
  • The original Falla's immediate reaction upon being passed over for the crown in favor of Luna was to throw a childish fit and whine that Luna didn't deserve it, before flying into a rage and destroying the entire kingdom after a fight with Luna cost her her left eye.
  • The new Falla also shows shades of this during Act IV. As she was Tsukune's girlfriend in her original timeline, she simply cannot accept that this world's Tsukune is dating Moka, to the extent that she throws a temper tantrum and screams that it isn't fair and goes so far as to rig the entire girl's dorm with Death Traps in an attempt to kill Moka. The final trap she sets is quite infantile; a Box-and-Stick Trap containing a blood pouch and a sign reading "Free Blood," which Falla genuinely expected Moka to fall for.

Evil Falla

• Ambition Is Evil: She wanted to become the queen of the chronoflies, which led to her killing her father and wiping out the entire species in a fit of rage when she was passed over.
• And I Must Scream: After being defeated by Luna, she was stranded in the time stream, with nothing better to do than shift all over time and the monster world.
• 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.
• Asshole Victim: After all of the horrible atrocities she's committed, including wiping out her entire species and razing a human city to the ground, no one has any sympathy to spare for her both times she dies.
• Ax-Crazy/Insane Equals Violent: She's a sadistic, sociopathic bitch who can slaughter people by the handful without hesitation, while laughing about it. Being afflicted with chrono dementia only makes it worse.
• Bad Is Good and Good Is Bad: She appears to run on this mentality. She's firmly convinced that, as a power-hungry warmonger, she deserved to be the queen more than Luna, whom she outright criticized and viewed as unworthy to have the crown for being a Nice Girl. In Act IV chapter 13, after successfully tricking Luna into restoring her magic, Falla openly complains about how much "nice crap" she had to do just to get Luna to cooperate.
• Cain and Abel: The Cain to Luna's Abel.
• The Caligula: While she was never officially declared the queen of their kingdom, Falla fits the bill in several ways. She's an absolute sociopath who only cares about herself and her own power, and sought to become queen so she could go on to become a warmonger and take over the entire world. In fact, her parents passed her over as queen in favor of Luna for this very reason: because she was too focused on the power to actually use it properly. Luna even tells her as such point-blank in Act IV, remarking that if Falla had become queen, her rule would have run their kingdom into the ground and wiped out their race. Ironically, Falla did exactly that when she found out that she was being passed over; she was so outraged at being passed over that she destroyed the entire kingdom and their entire species, declaring that no one will be queen if she can't be.
  Falla: Fine… so be it… if I can't be queen… NOBODY WILL BE!
• Card-Carrying Villain: While she never outright identifies herself as evil, she fits the criteria in several ways. She openly criticized both of her sisters for being Nice Girls, thought that being a power-hungry, bloodthirsty warmonger would make her a good queen, repeatedly compares those around her to worms and bugs, and, judging by her words to her Good Counterpart in Act V chapter 37, actually seems proud of having killed her own family and entire species.
• Cold-Blooded Torture: In Act V chapter 35, she subjects her Good Counterpart to this, slowly ripping her wings off piece by piece, chopping off one arm and one leg, and finally crushing one of her ankles, partially to get back at said Good Counterpart for killing her during Act IV, partially in an attempt to force Render and Leon to give up their keys to Pandora's Box, and partially just for her own sadistic amusement.
• Deader than Dead: During Act V, she's brought back as a disembodied soul by Babylon, and goes on a rampage through a human city before being subdued, with Kyouko personally crushing her head in with a baseball bat. As she was just a soul when this happened, Falla is erased from existence completely.
• Despotism Justifies the Means: Part of the reason she was passed over as queen in favor of Luna; as their mother pointed out, Falla was "too focused on the power to use it properly." Indeed, Falla openly admits that she only wanted the position for the power. Even after destroying the entire chronofly kingdom and committing genocide of her entire race, sans herself and Luna, all Falla can think of is the crown, even though, thanks to her, there isn't even a kingdom to rule anymore!
• Did You Actually Believe...?: In Act IV chapter 11, Falla gives the group this kind of speech after cutting Luna down and admitting that her attempts at redemption were merely an act all along:
  Falla: You seem so surprised. Surely you didn't truly believe that I had any intention of remaining here at this filthy school, being denied my magic and crown, being forced to remain by her side as an equal? You filthy worms, why would I ever choose family over power?
• Evil Cannot Comprehend Good: During Act IV, while mentioning Felucia's disappearance and Luna's death at her hands, she 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, and blows off Ms. Nekonome's teachings to co-exist amongst humans as "dribble." After bifurcating Luna in Act IV chapter 11^note  Luna is brought back a few chapters later, Falla outright tells Kurumu that she should be thanking her for doing so because now Luna won't be hounding Rason anymore.
• Evil Is Petty: She 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. Furthermore, it's revealed in Act VI that the reason Luna could never get a date is because Falla lied to all of her potential suitors that their father would execute any of them who tried to approach Luna without hesitation, for no reason other than to be a Jerkass.
• Falsely Reformed Villain: During Act IV. In an effort to get Luna to finish the spell and restore her magic, she fakes wanting to reform through several acts of kindness... and in chapter 11, as soon as Luna truly believes that Falla can change and restores her magic, Falla promptly bisects her in cold blood and then proceeds to rub it in the gang's faces that it was all an act.
• The Farmer and the Viper: Even after finding out that Falla was a Jerkass who murdered her own father and sister and caused the extinction of her entire species sans herself and Luna, Kyouko tries to reach out to her and reform her. It seems to work, and Luna eventually restores Falla's lost chrono magic to give her a chance. As it turns out, Falla was faking a Heel–Face Turn to trick Luna into doing exactly that, and as soon as she does so, Falla bifurcates Luna and proceeds to rub in Tsukune and the others' faces how stupid they were to believe that her attempts to reform were ever anything but an act.
• Faux Affably Evil: She can act polite and refined when it suits her, but is nevertheless a complete Jerkass who is incapable of caring for anyone but herself. And even when she does try to act polite, everyone around Falla knows that she's a sociopathic bitch and don't buy it for a second.
• Hate Sink: Falla goes out of her way to be as despicable as possible. She sent her own little sister to her death out of spite and slaughtered her entire species and destroyed her hometown in a fit of rage, all simply because she was denied what she believed was her right to rule the chronofly kingdom, and is above all else a smug Jerkass who believes It's All About Me and has a Lack of Empathy that's borderline sociopathic.
• It's All About Me: By her own admission, all she cares about are herself and acquiring power for herself: everything else, including her own family, is a distant second.
• Jerkass: To describe her as a massive bitch would be an understatement. In fact, while pretending to reform in Act IV, the minute she drops the act in chapter 11, she outright says that she's tired of enduring "this nice crap."
• Jerkass Has a Point: In Act IV chapter 6, her statement that Yokai Academy's teachings on co-existing with humans are really more about hiding amongst the humans for their own survival does make sense in retrospect, especially since in that same conversation, Ms. Nekonome mentioned outright that any humans who enter the monster world will be Killed to Uphold the Masquerade, and monsters must hide their true forms when among the humans or be killed themselves.
• Lack of Empathy: Her disregard for other people's lives 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.
• Loves the Sound of Screaming: On two separate occasions, she openly urges Tsukune's posse and Kyouko to scream and beg for their lives before she kills them.
• Manipulative Bitch: She 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.
• My Species Doth Protest Too Much: The chronoflies were all stated to be a peaceful race who kept to themselves, but Falla is a sadistic, sociopathic Jerkass who views all other races as Pitiful Worms, wants power for power's sake, and doesn't give a damn about anyone who's not her, not even her own family.
• Pitiful Worms: She likes to refer to both humans and other monsters as ants.
• Pragmatic Villainy: In Act III, she 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 from her prison.
• Sadist: Case in point: in Act V chapter 35, she gleefully tears her Good Counterpart's wings, arm, and leg off and crushes her ankle.
  Kyouko: You... how could you?
  Evil!Falla: Very easily, actually.
• Smug Super: Due to her chrono magic, she's firmly convinced that she's a big shot, and all those around her, human and monster alike, are nothing but Pitiful Worms.
• The Sociopath: Has shades of this. Intelligent and manipulative? Check; she managed to easily manipulate Kyouko and ultimately trick Tsukune's group, who know from what Falla's good sister Luna told them that Falla is a heartless bitch, into thinking she wants to be come a good person. Complete Lack of Empathy and moral conscience? Check; Falla went so far as to send her own little sister Complica to her death For the Evulz, and later outright admitted to Luna and their mother that she viewed Complica as a disgrace to their species and she's happy that her younger sister is dead. Sadistic streak? She gleefully cut off her Good Counterpart's wings, arm, and leg, states afterwards that it was "very easy" for her to do so, and relishes the pain of others to the extent that she openly tells her opponents on more than one occasion to scream and beg for mercy before they die. On top of it all, she comes right out and says that nothing matters to her more than herself and power, not even her own family, and goes so far as to mock Tsukune and co. for ever believing that she would "choose family over power."
• Stupid Evil: Despite having personally destroyed the chronofly kingdom in a psychotic rage, essentially rendering her efforts to take over worthless, all she can think about is obtaining the crown.
• This Cannot Be!: After literally tearing her Good Counterpart to pieces in Act V chapter 35, she has this reaction when Good!Falla, having been reconstructed by Ceal, saves Kyouko from death at her hands and attacks her.
• Turned Against Their Masters: When she's brought back as a soul by Babylon in Act V, alongside Jovian and Jacqueline. Falla turns on him when she learns of Pandora's Box, planning to use it to restore herself to life on the grounds that she hates taking orders from anyone and that even Cessation of Existence would be better than serving Babylon. She just gets killed again and erased from existence for her trouble.
• Virtue Is Weakness: She had nothing but contempt and disgust for both Luna and Complica because of their Nice Girl attitudes; she even went so far as to send Complica to her death based on this, deeming her a disgrace to their species.
• Wants a Prize for Basic Decency: Taken up to eleven; in Act IV chapter 11, after bisecting Luna, Falla tells Kurumu that she should be grateful to her for doing so since she's ensured that Luna won't ever hound Rason again, and outright accuses her of being an Ungrateful Bitch when she doesn't do so. Even before that, in chapter 6, Falla points out to everyone in Ms. Nekonome's class that they should be grateful to her, because had she not intervened in the timeline, everyone would have died; aside from the fact that no one but Tsukune's group has any idea what she's talking about, the only reason Falla helped to avert Luna's Suicidal Cosmic Temper Tantrum at the end of Act III was purely to serve her own interests, as Luna was the only one who could free her from her prison.

Good Falla

• Amnesiac Dissonance: In Act IV, she 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.
• Arson, Murder, and Jaywalking: In chapter 17 of Act IV, she tries to kill Moka by rigging the entire girls' dormitory with various Death Traps, including piano wire, spiked pits, swinging logs... and a rabbit-style box trap with a free packet of blood.
• Box-and-Stick Trap: After rigging the entire girls' dorm with Death Traps in an effort to kill Moka, Falla's final trap is this, along with a blood pouch and a sign reading "Free Blood." Moka is actually offended that Falla thought she'd go for it.
• 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.
• Easily Forgiven: While this is common amongst Tsukune's group, Falla's case in Act IV is the most ridiculous example; she rigged the entire girls' dormitory with Death Traps in order to kill Moka so she could have Tsukune, and did this of her own volition, before she looked into Lilith's Mirror and briefly turned evil again. Kurumu even points out how ridiculous that is... only for the others to openly dismiss her.
• Entitled to Have You: Her attitude toward Tsukune for most of Act IV. While she knows that this Tsukune is not the same one from her timeline, she doesn't care and is adamant that he's rightfully hers, going so far as to rig the entire girls' dormitory with Death Traps to kill Moka and Make It Look Like an Accident so she could have him back. She finally snaps out of it when Lilith's Mirror restores her memories, deciding she's not worthy to have Tsukune due to the atrocities she committed in the past.
• I Hate Past Me: Her reaction in Act IV chapter 22 when she regains her memories and is shocked to discover what an entitled sociopath she was, up to and including sending her younger sister to her death out of spite and annihilating her entire kingdom, family, and species in a fit of rage because she was denied the crown. When fighting her Evil Counterpart in Act V chapter 37, she is adamant that she is nothing like said Evil Counterpart and Evil!Falla is the true monster who did all that.
• Murder the Hypotenuse: In Act IV, she attempts to kill Moka by setting up various Death Traps in the girls' dormitory in order to Make It Look Like an Accident; the others even point out how stupid this is, considering the fact that Tsukune would hate her for doing so. 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.
• My God, What Have I Done?: She has this reaction upon regaining her memories.
• Nice Job Breaking It, Hero: 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.
• Story-Breaker Power: Her chrono magic makes her among the most powerful in Tsukune's group. Naturally, the author keeps coming up with ways to keep her from going all out to prevent her from rendering everyone else useless, such as the Almighty's law forbidding her from actual Time Travel, the risk of chrono dementia, the risk of getting preyed upon by chrono wraiths, and Babylon keeping track of her chrono magic in order to capture her.

Complica Cii

Luna and Falla's deceased little sister. She returns to life in an undead state in Acts V and VI. In the final chapter of Act VI, she becomes an anomaly in existence similar to Hex Lagon, ultimately replacing herself in the main universe with an Alternate Self who's world was destroyed.

• 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. In the first chapter of Act VII, she returns as an Anthropomorphic Personification of time.
• Cain and Abel and Seth: The Seth to Luna's Abel and the original Falla's Cain.
• Death by Origin Story: As revealed in flashbacks in Act III, she cast the forbidden Chrono Displacement spell to get one more day to play with a boy she liked, and then perished as a result of the spell's repercussions.
• Horrible Judge of Character: In Act VII chapter 3, the new Complica decides to trust Routier right off the bat. While Routier did save her from a group of human pedophiles, she did so by ripping them to shreds with a chainsaw and laughing about it.
• Last Request: Her final request to Arial before she dies in Act VI chapter 52 is that Arial ease up on Mizore and give her a fair chance, because Dark and Mizore truly love one another. Arial reluctantly agrees, if only because Complica is her best friend.
• Loophole Abuse: As her nature as an anomaly prevents her from directly interfering in the events of her home world or warning Moka about what's coming in Act VII, she gets around it by pulling an Alternate Self out of a soon-to-be-doomed reality.
• Motor Mouth: She's known to talk so fast and so much at once that she forgets to take a breath and passes out.
• Odd Friendship: With Arial. The only thing the two really have in common is that they're monster children who died, and they have near polar opposite personalities. Complica is a calm and sweet Nice Girl, while Arial is a stubborn and immature Jerk with a Heart of Gold with a Hair-Trigger Temper that borders on Ax-Crazy. That being said, the two do get along very well, with Arial even agreeing to give Mizore a fair chance to prove herself worthy of Dark because Complica begged her to do so on her deathbed.
• Photographic Memory: She created a copy of the Chrono Displacement spell in Heaven from memory.
• Potty Failure: She has a bed-wetting problem.
• Year Inside, Hour Outside: While she returns to the world as an anomaly mere hours after her death and rebirth, from her perspective, it was "6,789,241 years, 8 months, 22 days, 14 hours, and 16 seconds."

Ghaldin Rayazo

A mercenary and Evil Sorcerer and Apoch and Astreal's former master.

• Arc Villain: He's the main threat for the first few chapters of Act I, with Apoch and Astreal trying to find someone to defeat him for them and set them free.
• Asshole Victim: Everyone agrees that he deserved to die.
• Bad Boss: In his short appearance, he physically abuses the Ezranas and declares them to be nothing but his tools to use as he wishes. Small wonder why they ran away from him. A deleted side story detailing Apoch and Astreal's birth reveals he was even worse to their predecessor Astroch, abusing her for the smallest of slights, like serving him bread and water even though she rightfully points out she doesn't know how to cook, and outright using her as a Sex Slave.
• The Dreaded: He's known to be a feared and powerful combatant in the monster world.
• Fury-Fueled Foolishness: He has Inner Moka on the ropes and is about to break her neck... but when Astreal destroys his Mind-Control Device after Yukari severed it from his wrist, he immediately drops Moka, leaving her alive in the process, to kill them both in a rage. Needless to say, Moka quickly recovers and kills him by ramming her arm through his back.
• Impaled with Extreme Prejudice/Torso with a View: Moka kills him by ramming her arm clean through his heart.
• Jerkass: He's smug, cruel, and a Bad Boss to the Ezranas, and takes advantage of their failed attempt to brainwash Dark and Rason to enslave them to his own will, the first thing he orders them to do being to kill Mizore and Kurumu, their respective girlfriends. Within mere minutes of his introduction, one can easily tell why Apoch and Astreal ran away.
• Kick the Dog: Once he reinstates his control over the Ezranas, rather than break their spell over Dark and Rason, he decides on a whim to make them his slaves as well, forcing them to attack Tsukune and co. while directly ordering them to kill Mizore and Kurumu, their respective girlfriends. All with a smile on his face.
• The Sociopath: He's a cruel and sadistic mercenary who sees the Ezrana sisters not as people, but as Living Weapons he can use however he pleases, physically and verbally abusing them whenever they defy him or disobey even the slightest order. When he appears to reclaim them in Act I and discovers they placed a mind control spell on Dark and Rason to kill him for them, only for it to barely function at all, rather than simply break the spell and take his leave with the Ezranas, he decides on a whim to seize control of them for himself for the sake of having powerful servants, directly ordering them to kill Mizore and Kurumu, their respective girlfriends, by ripping their hearts out all with a smirk on his face.
• Villain Ball: When Astreal destroys his Mind-Control Device after he drops it, he's so furious that he promptly turns on them when he has Inner Moka at his mercy and prepares to kill them... and gives Inner Moka the perfect opportunity to take him down.
• Your Head Asplode: After Moka kills him, Dark, in a fit of rage at being controlled, stomps his skull into a bloody stain.

Rarosun and Surason Kiyo

A pair of shapeshifting brothers who serve Dahlzin Aragaso.

• Divide and Conquer: In Act I, in order to weaken Tsukune and Moka's defenses, they shapeshift into Dark and Rason and molest Kurumu and Mizore, respectively, in order to dupe Dark and Rason into fighting and killing one another. The plan would have succeeded if not for the Villain Ball moment below.
• Evil All Along: They initially appear to be good people, 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.
• Evil Gloating: In Act I chapter 30, after trapping Kurumu and Mizore behind a barrier while Rason and Dark are fighting, they 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.
• Impaled with Extreme Prejudice: Rason kills one of them by impaling him on a broken tree.
• Villain Ball: In Act I chapter 30, they 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.

Kenzo Shikazan

An ex-member of Fairy Tale and an old friend of Dark and Felucia.

• Defector from Decadence: He ultimately left Fairy Tale when he got sick of being used as a pawn.
• The Dog Bites Back: After being killed by Kuyou and Hokuto, the latter of whom being indirectly responsible, during Act III, he's shown in the final chapter of Act IV torturing the two of them in Hell.
• Eyepatch of Power: He wears a patch over his right eye.
• Intergenerational Friendship: With Felucia; Kenzo is old enough to be balding, whereas Felucia is a teenager.
• Killed Offscreen: By Kuyou (and indirectly Hokuto) during Act III.
• Sudden Sequel Death Syndrome: He first appeared in Act II, and is Killed Offscreen in Act III by Kuyou, who was acting on Hokuto's orders.
• Super Smoke: He's a smoke demon.
• Unwitting Instigator of Doom: As revealed in Act III, he 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, Hokuto finds this out and sends Kuyou after Kenzo in order to discover its 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.

Talon Ryashen

A hybrid monster experimented on by Fairy Tale, who now seeks revenge against the entire organization.

• Anti-Villain: Type I or II. He's obsessed with murdering everyone who has ever been associated with Fairy Tale and so far, cannot be reasoned with. Regardless, as he puts it, after being turned into what he is now, his family rejected him, and all he has left to live for is revenge on the organization.
• Benevolent Boss: His treatment of Rin, Jovian, and Jacqueline. In Act VI chapter 53, he outright states that he sees the three of them as equals, not servants.
• Black-and-White Insanity: He runs on this throughout Act VI. As far as he's concerned, anyone and everyone who was ever a part of Fairy Tale for any reason is irredeemably evil, equally responsible for what happened to him, and has to die. This includes Dark, Akua, and Kahlua, who defected from the organization and were instrumental in the defeat of Alucard.
• Blade Below the Shoulder: One on each hand.
• Disney Death: Up until Act VI, Dark, Felucia, Akua, and Kahlua all believed him to be dead. He wasn't.
• Half-Human Hybrid: Became half-monster after being injected with Alucard's blood.
• He Who Fights Monsters: He's 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.
• It's Personal: Fairy Tale kidnapped him off the streets and turned him into a monster.
• Knight Templar: 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 for what they did to him. 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. Case in point: despite knowing that Dark left Fairy Tale a long time ago and is one of the heroes who slew Alucard, Talon flat-out states that he doesn't care; all that matters is that Dark was a member of Fairy Tale, and thus is irredeemably evil in his eyes.
• No Sympathy for Grudgeholders: He's out to kill everyone who was ever a part of Fairy Tale for any reason because they kidnapped him off the streets and turned him into a Half-Human Hybrid. It's not enough that the ones who were truly responsible for his transformation are already dead; Talon blames everyone in Fairy Tale for his condition, regardless if they were simply receptionists or Unwitting Pawns, and strives to kill them all. For this reason, even Tsukune's group (sans Kyouko) deem him a violent psychopath who needs to be stopped.
• 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.
• Red Baron: Most know him as "the Fairy Tale Killer."
• Revenge Before Reason: Several characters have pointed out to him that the Fairy Tale operatives who turned him into a monster are long dead. Every time, Talon flat-out states that he doesn't care; in his eyes, everyone who was ever a part of Fairy Tale for any reason is equally responsible for his condition, and he won't stop until they're all dead. It's even noted by other characters discussing his crusade that Talon simply will not listen to reason.
• Roaring Rampage of Revenge: Against Fairy Tale.
• Sherlock Scan: He's quite skilled at this. In Act VI chapter 22, upon coming to after his ill-fated battle with Akua and Kahlua, he figures out where exactly he is in the infirmary without even looking around before going over his own physical state with an analytical mind and determining exactly how wounded he is. In chapter 43, after seeing Ling Ling shrug off all of his, Jovian, and Jacqueline's attacks, up to and including decapitation and getting shot in the heart, he takes note of Ling Ling's jiang-shi dress, immunity to pain, and the fact that she's still moving despite all of their attacks, and deduces that Ling Ling is undead.
• Stealth Expert: He manages to sneak into the Shuzen castle, unnoticed by the guards and Akua and Kahlua themselves, on two separate occasions.
• Super-Soldier: What Fairy Tale intended to make out of him. They succeeded.
• Was Once a Man: He was once an ordinary human until Fairy Tale kidnapped him off the streets and used him in Super-Soldier experiments.
• Winged Humanoid: He has metallic, bat-like wings.
• Woobie, Destroyer of Worlds: 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.

Jovian and Jacqueline Kikion

Evil Counterparts of Apoch and Astreal who were enhanced by Alucard's blood, and directly serve Hokuto. After their deaths in Act IV, they are pulled out of Hell by Babylon to serve him in Act V, only to end up Deader than Dead. In Act VI, their spell is found by Talon, who resummons them to work for him, with the re-summoned sisters being far more redeeming than the originals.

• Ambiguously Evil: While the original Jovian and Jacqueline were nothing but pure evil through and through, the new Kikions summoned by Talon during Act VI are considerably more sympathetic, having several instances of genuine compassion and empathy.
• Anti-Villain: As they explain to Rin in Act VI, their morality (or lack thereof) is shaped by that of their master(s), and they're not naturally good or evil on their own.
• Artificial Human/Pure Magic Being: Like Apoch and Astreal, they're summoned beings created by magic.
• Asshole Victim: In Act IV chapter 28, they're 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.
• Ax-Crazy: 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. During their major fights in Acts IV and V, they deliberately go above and beyond to kill as many innocent people and cause as much collateral damage as possible simply, in their words, "because it's fun." The resummoned Jovian and Jacqueline in Act VI are considerably more mellow.
• Back from the Dead: They are resummoned by Talon in Act VI.
• Be Careful What You Wish For: Several times during the climax of Act IV, they both remark that they want someone to "go splat." Astreal fulfills this desire by subjecting Jacqueline herself to a Disney Villain Death.
  Apoch: You wanted someone to go splat, did you not?
• Berserk Button: They do not like the idea of being duplicated or copied in any way, including being victims of Power Copying.
• Catchphrase: Whenever someone makes a comment on their relationship, they dismissively state, "What do we care? We're made from magic."
• Co-Dragons: They served as this to Hokuto, and now new versions of them serve as ones to Talon.
• Cold-Blooded Torture: During Acts III and IV, they eagerly inflict this on Felucia, both physically and sexually, for days on end.
• 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.
• Deadpan Snarker: Jovian dips into this during 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.
• Disney Villain Death: Jacqueline is killed when Astreal blows out the floor of the sundeck she's standing on, leaving her to fall to her death.
• The Dreaded: As revealed in Act IV chapter 2, both Akua and Kahlua are terrified of Jovian and Jacqueline, having seen their massive destructive capabilities, particularly the fact that they single-handedly destroyed entire Fairy Tale facilities during temper tantrums. Upon finding all of this out, Tsukune and co. are not too eager to fight them either.
• Exotic Eye Designs: 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.
• Evil Counterpart: Like Apoch and Astreal, 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 Feels Good: The original Jovian and Jacqueline openly admit that they do such things as rape, mass murder, and mass destruction simply "because it's fun."
• Faux Affably Evil: They 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 that were resummoned by Talon in Act VI are far more genuinely Affably Evil.
• For the Evulz: 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.
• Half the Man He Used to Be: In Act IV chapter 28, Apoch kills Jovian by slicing her in two at the waist. Later, in Act V chapter 36, Leon kills the revived Jacqueline by using her own Wave-Motion Gun attack, which he copied, to completely vaporize her from the waist up.
• Invincible Villain: They're 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.
• Ironic Hell: In life, Jovian and Jacqueline brutally tortured Felucia, both physically and sexually, to the point of madness for days on end while holding her captive. Upon their deaths at the end of Act IV, they're sent to Hell, where the also-dead Felucia eagerly seizes the chance to torture them back. To add to the irony, as shown in a flashback in Act IV chapter 31, Felucia had earlier sworn to Jovian and Jacqueline that when they died, Felucia would be waiting for them in Hell to pay them back, which Jovian and Jacqueline smugly laughed off.
• Jerkass: Hokuto's versions of them count to a T; even at their "nicest," Jovian and Jacqueline are nothing but heartless bitches who absolutely delight in causing pain and mass destruction wherever they go.
• 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.
• Kick the Dog: Befitting their twisted personalities, Hokuto's Jovian and Jacqueline live to pull off as much puppy-punting as they can. Such gems include raping and torturing Felucia to the point of Sanity Slippage for days on end, shooting the original Apoch dead in cold blood right in front of Tsukune and Ruby, raping Tsukune's cousin Kyouko and then bragging about it to Tsukune over the phone, and casually blowing up Tsukune's house right in front of him. To really drive the point home, in all of their major fights with Tsukune and co. in Acts IV and V, they deliberately go out of their way to kill as many innocent people and cause as much collateral damage as possible simply because they can.
• Lack of Empathy: They 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 life around them. 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.
• Moral Myopia: 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.
• Only One Name: The new Jovian and Jacqueline in Act VI; when Headmaster Mikogami addresses her by her full name, Jovian responds with confusion:
  Jovian: Kikion? Is that what my predecessor in this world went by?
• Perpetual-Motion Monster: Thanks to their enhancements with Alucard's blood. They have no known limit to their power levels, and can fight non-stop without ever tiring.
• Pitiful Worms: In Act V chapter 36, during the school attack, Jacqueline outright refers to the humans as "filthy bugs."
• Post-Rape Taunt: 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."
• The Power of Blood: They were injected with Alucard's blood, and their barriers and energy blasts are far more powerful than Apoch's and Astreal's as a result.
• Psycho for Hire: While working for Hokuto; while they're largely operating under his orders, they'll even kill people they haven't been ordered to kill just because they can.
• Psycho Lesbian/Rape Is a Special Kind of Evil: They sexually abuse both Felucia and Kyouko while holding them hostage at different points.
• Psychopathic Manchild: The original Jovian and Jacqueline Kikion who served Hokuto are a Type C and D combined. They're both incredibly powerful and nearly unstoppable Hot Witches... and they're also completely Ax-Crazy Psycho Lesbians whose idea of fun involves such things as Cold-Blooded Torture, rape, and committing acts of wanton mass murder and city-wide destruction as a matter of course; they even explicitly describe their fights with Tsukune's group, during which they deliberately go above and beyond to kill as many innocent people and cause as much widespread destruction as possible, as "playing." To drive the point home, in Act III chapter 42, Jovian even cheers "Yay, I love killing!" in what the narration explicitly describes as a playful tone, 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."
• Put the "Laughter" in "Slaughter": During the climax in Act IV, they absolutely thrive on the destruction and death they cause as they reduce a great deal of Tsukune's hometown to rubble.
• Readings Are Off the Scale: In Act IV chapter 2, Akua describes their power levels as "immeasurable."
• 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."
• 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 pissed to discover this.
• Squishy Wizard: Hokuto's Jovian and Jacqueline; they're noted to have immeasurable magical reserves, with Apoch's Laser Blade and their own powers being the only known weapons or powers thus far that can actually penetrate their barriers or deflect their energy beams, but have been shown to be rather poor physical fighters. In both of their major fights in Acts IV and V, the minute someone actually bypasses their defenses, they go down rather easily.
• 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.
• There Is No Kill Like Overkill: 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.
• This Cannot Be!: Their reaction in Act IV chapters 27 and 28 when it's revealed that Apoch's Laser Blade can shatter their barriers and reflect their energy blasts. Hammered home because it had been stated by multiple sources that their attacks are unblockable and their shields are impenetrable.
• 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.
• Undying Loyalty: The original Kikions' 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.
• 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, their temper tantrums put Kahlua's Berserker Tears to shame.
• Villainous Incest/Twincest: They have a definite thing for each other.
  Hokuto: Such strange love you two have.
  Jovian & Jacqueline: What do we care? We're made from magic.

Ceal Erres

A "catalyst mage" and dragon slayer that`falls in with Tsukune's group during Acts V and VI.

• An Arm and a Leg: He lost his left hand to Pandora's Jackass Genie tendencies, and replaced it with biological matter from a necro demon.
• Anti-Hero: 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.
• Body Horror: He can use his magic to manipulate organic matter, allowing such feats as skinning his opponents alive. He also mentions in Act VI chapter 45 that he absorbed biological matter from several of Pandora's pets into his own body.
• Cynicism Catalyst: The reason for his Jerkass personality is because his little sister died trying to save someone from getting hit by a car. As he explains, his sister could have been a great doctor someday, but threw it all away for the sake of compassion.
• Dramatic Dislocation: In Act VI chapter 45, Dark breaks his ankle; he simply pops the bones back into place.
• Fluffy Tamer: His pet necro demon, Xarai.
• Good Is Not Nice: He 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, to the extent that in some cases he has to be begged to do so, and can barely open his mouth without talking down to everyone around him.
• Healing Hands: He is an excellent healer, and can even manipulate biological matter to restore others' lost limbs and organs. However, he does have his limits; in Act VI chapter 44, he is unable to revert the brain damage Sun suffered after Kokoa punched her without a separate spell.
• 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").
• Honor Before Reason: As a dragon slayer, honor is very important to him.
• Jerk with a Heart of Gold: He's a bit of a jerk, yes, 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.
• Magic Knight: A powerful magic user and fighter who is strong and fast enough to hold his own against Dark in a fight.
• 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.
• 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.
• Red Right Hand: His left hand is black and scaly.
• 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.
• Super Drowning Skills: As stated above, he doesn't know how to swim.

Xarai

Ceal's pet necro demon.

• Bizarre Alien Biology: He's mentioned to have "many stomachs."
• Combat Tentacles: He has quite a few of them.
• The Faceless: The most we've seen of him so far are his tentacles, as well as a mouth filled with More Teeth than the Osmond Family.
• Healing Factor: He can regenerate tentacles instantly.
• Kryptonite Factor: Fire is mentioned to cause him discomfort.

Render Asaga

A battle mage who falls in with Tsukune's group during Acts V and VI, becoming romantically involved with Apoch.

---

• All Men Are Perverts: In Act VI, he's also quite excited to see Apoch and Astreal's fights over which of them has bigger breasts, said fights typically resulting in Clothing Damage.
• Blood Knight: As a battle mage, he's, as he puts it "always ready for a fight."
• Cool Sword: His weapons are a pair of swords inscribed with magical runes that he created himself; thus far, they're the only known objects, aside from Alucard himself, that Apoch's Laser Blade can't cut through.
• Deadly Dodging: In Act V chapter 36, 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.
• Dual Wielding: His primary weapons are a pair of magically summoned swords.
• Expecting Someone Taller: In Act VI chapter 19, upon discovering that Moka is the daughter of Issa Shuzen, he remarks that he expected the daughter of a dark lord to look more intimidating.
• The Knights Who Say "Squee!": In Act VI chapter 45, he speaks of Akasha in a fanboy-esque manner, even thinking about getting her autograph.
• Super Mode/Hulking Out: When he fights, he triples in muscle mass.
• Trademark Favorite Food: Caramel frappés. Leon even accuses him of being addicted to them.
• What the Hell, Hero?: During Moka's "The Reason You Suck" Speech to the HDA in Act VI chapter 25, he puts his own two cents in by criticizing them for still mistrusting and aiming their guns at them even after Astreal shot down the rylo demon that was tormenting the city.

Leon Takeda

A mimic mage and Render's partner, who becomes Astreal's boyfriend.

• Anime Hair: His hair is quite spiky.
• Awesomeness by Analysis: He can mimic any magical power he sees.
• Hawaiian-Shirted Tourist: Constantly wears a blue tropical shirt.
• The Mourning After: His late lover Selena, who was killed by a gang of rival treasure hunters while they were searching for the keys to Pandora's Box. Part of the reason Leon seeks to open the box is so Selena's death wasn't in vain.
• Pocket Protector: As revealed in flashback during Act V chapter 29, he survived being shot thanks to a locket he was wearing.
• Power Copying: As a mimic mage, he can copy and use magic spells, though not monster abilities; for example, he can copy Apoch's Deflector Shield or Astreal's Hand Blast, but not Dark's invisibility or Mizore's cryokinesis.
• Tragic Keepsake: A locket Selena gave him, which saved his life when he was shot.

Razico Kalashin

A warlock and treasure hunter who becomes romantically involved with Ruby.

• Badass Cape: A black one.
• Bait-and-Switch Comment: In Act VI chapter 36, Kurumu and Yukari fondle Apoch and Astreal's breasts to see who's are bigger, only discovering afterwards that there was a tape measurer off to the side the whole time and they just did so for nothing. As Apoch and Astreal are about to take revenge on the two, Razico yells "Hold it!", and we briefly think he's trying to break up the fight. Instead, he reminds Apoch and Astreal that they've already caused enough damage to Fang Fang's home, and orders them to take it outside.
• Casual Kink: He's all too eager to indulge Ruby's masochism.
• Chain Pain: His primary weapon is a magically conjured chain.
• Gentleman Thief: 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.
• Insistent Terminology: A Running Gag is the others referring to him as a thief rather than a treasure hunter.
• Power Perversion Potential: The chains he uses see quite a bit of use in his and Ruby's love sessions.
• Something about a Rose: After their first meeting, he gives Ruby a black rose. She takes to wearing it in her hair.

Hex Lagon

A mysterious Reality Warper who pulls off such feats through games of chance, as well as the son of Babylon.

---

• Absurdly High-Stakes Game: By his own admission, he likes to gamble big, with his games typically being whatever his opponent wants him to do against such things as Gabriel's angelic status or the hearts of beautiful women.
• Abusive Parents: He outright says that he doesn't consider Babylon his father in any sense aside from the fact that the man gave him life.
• Ascended Extra: Hex originates from another fic written by the author entitled Rosario Vampire: A Game of Chance. In fact, a chapter in Brightest Darkness proper has him explain to everyone what exactly happens, showing that the two stories are parallel but alternate universes.
• Big Brother Instinct: His sole concern is to free Pandora from her imprisonment in Pandora's Box.
• Blue-and-Orange Morality: He outright states that he doesn't care whether or not the human and monster worlds are destroyed in the war with Babylon, and is on no one's side but his own.
• The Gambler: He uses luck and chance as the guiding forces for his powers.
• Graceful Loser: He doesn't really care if he wins or loses at his game; it's all a part of luck, after all.
• The Hedonist: He admits that he likes gambling for the hearts of beautiful women, and when not trying to save Pandora, he spends his time living it up in bars and nightclubs.
• Jackass Genie: To an extent. For example, as part of his bet with Gabriel when Gabriel plays his game, if Gabriel loses, he will be stripped of his grace and place in Heaven. As the others point out, Gabriel losing his wings was not part of the terms Hex mentioned.
• Jerkass Has a Point: While he plays an Absurdly High-Stakes Game and is very callous, he nonetheless makes a valid point when he tells the others that they have no complaints against playing his game until they start losing.
• You Have No Chance to Survive: He outright tells Moka and co. on several occasions that, as far as he's concerned, they have no chance at defeating Babylon, considering the fact that countless other worlds have fallen to him.

Pandora

Hex's little sister, currently trapped in none other than Pandora's Box.

---

• Abusive Parents: Babylon trapped her in the box because she refused to help him with his plans of conquest.
• Blue-and-Orange Morality: Like Hex, Pandora has little concern with the affairs and morality of "lesser beings."
• Chaos Is Evil: She thrives on chaos and anarchy, but is more Chaotic Neutral than truly evil.
• Jackass Genie: She tends to twist her wishes around for laughs.

Jenner Rythmore

A member of the Human Defense Agency founded after The Masquerade is broken.

• Blatant Lies: In Act V chapter 39, he declares on national television that he trusted monsters and allowed them into the human world. It falls flat considering that every minute of his screentime beforehand was spent openly lambasting and distrusting monsters as a threat, to the extent he declared he was just waiting for an excuse to declare open war on the monster world.
• General Ripper: 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.
• Give Me a Reason: In Act V chapter 20, he states outright that he'll take the first possible excuse he can to declare open war on monsters.
• Holier Than Thou: Ceal accuses him of being such in Act VI chapter 6; Jenner constantly rants about how monsters all all the same and do nothing but lie and kill. Ceal retorts that humans are hardly any different, that Jenner speaks as if humans are all universally good and pure, and declares that for all his talk about wanting to protect humanity, all he really is is a human who thinks he's above monsters just because he's human.
• "It" Is Dehumanizing: He outright refers to monsters as "things" on multiple occasions.
• Jerkass: 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.
• Just Desserts: He spent all of his screentime ranting about how monsters are Always Chaotic Evil and declared open war on them the first chance he got. In Act VI chapter 6, Ceal, after giving him a chance to back down and live, throws him to the dragon Babylon sent after Sun, which devours him whole.
• Sudden Sequel Death Syndrome: Early on in Act VI, he's murdered by Ceal in self-defense.

Hothorne Tamaka

The director of the Human Defense Agency, and Jenner's replacement.

• Hypocrite: 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.
• Redeeming Replacement: To Jenner Rythmore, his predecessor. Hothorne is a Reasonable Authority Figure who admits that he doesn't believe that all monsters are evil, whereas Jenner was a General Ripper who declared open war on the monster world at the first opportunity.
• Reasonable Authority Figure: He's not as prone to Van Helsing Hate Crimes as his men, and even peacefully meets with Moka and Akasha to negotiate. During this time, he even admits that he doesn't really think that all monsters are evil.

Gabriel Rulion

One of Rason's fellow angels and close friends.

• Broken Angel: In Act VI, he loses his angelic grace and powers after losing Hex's game, which also costs him his wings. However, shortly after, Ceal restores his wings, though he cannot restore his grace.
• Broken Pedestal: In Act VI, despite initially insisting on adhering to the angels' Thou Shalt Not Kill Muggles rule, he ultimately changes his mind once he sees the extent of the HDA's anti-monster campaign.
• Good Wings, Evil Wings: He initially has generic white-feathered wings, though they are restored with black feathers after he loses Hex's game.
• Insecure Love Interest: He proves to be this for Luna. In Act VI chapter 46, when faced with the possibility that he's Luna's Destined One, he's not so sure, believing he's not worthy of her because she's a queen while he's failed her again and again.
• Red Is Heroic: He's red-haired, and an angel who looks out for humanity.
• Violence Really Is the Answer: During the early part of Act VI, Gabriel repeatedly objects to the gang killing members of the HDA, in part because of the angels' code that humans are sacred and untouchable no matter what, despite the fact that the HDA is openly anti-monster and is actively trying to kill him along with the other members of the gang. Eventually, Ceal gets sick of it and subjects Gabriel to a Sadistic Choice, either to kill Ceal himself to stop him from killing an HDA officer, or to stand back and watch as Ceal does so. Gabriel chooses to Take a Third Option by Mercy Killing the officer to spare him a slower and more agonizing death at Ceal's hands, and from that point on, resolves to do whatever it takes to save his friends, even if it means killing the humans he's sworn to protect.
• You Are Worth Hell: He gives up his angelic wings and status in an effort to help Luna.

Dahlzin Aragaso

A Vampire Monarch who seeks Tsukune and Moka's blood to overthrow Issa Shuzen.

• Arc Villain: He's the overarching threat of Act I.
• Lone Wolf Boss: He's the only villain of the series to have no connections whatsoever to Fairy Tale or Babylon.
• Villainous Breakdown: After Tsukune repeatedly gets the better of him during the final showdown, he snaps, deciding he no longer wants Tsukune's blood and to just kill him.

The Lord of Hell

The lord of Hell, and Kurumu's biological father.

• Disappeared Dad: He conceived Kurumu with Ageha after a one-night stand; Ageha, fearing how Kurumu may react, withholds his identity from their daughter, simply telling Kurumu that her father was "a world-class asshole who didn't call the next day."
• Even Evil Has Loved Ones: He may be a Disappeared Dad, but he 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.
• Everyone Calls Him "Barkeep"/No Name Given: So far, he's just been called the Lord of Hell.
• The Faceless: He's always shrouded in darkness, except for his red eyes.
• Get A Hold Of Yourself Man: After Kurumu's Death by Despair in Act V, the Lord of Hell calls her soul to Hell to criticize her for giving up so easily, which motivates her to unlock her full potential as the Princess of Hell and return to life.
• Luke, I Am Your Father: He's revealed to be Kurumu's father as early as Act II, but it isn't until Act V that Kurumu herself finds out.
• Satan Is Good: He wants what's best for Kurumu, and hopes to thwart Babylon's invasion. He even seems to be on at least speaking terms with the angels in Heaven, having sent word up to them on the magical wristband that Felucia left behind in her haste.

Babylon

The Big Bad of Acts V and VI, and Hex's father. He's a Multiversal Conqueror who has his sights set on our world.

• 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.
• Bad Boss: He's depicted as such in Acts V and VI. In the former, he subjects the Otonashi sisters to Electric Torture in front of Tsukune and the others, and when pulled out of Hell by him late in Act V, Evil!Falla, Jovian, and Jacqueline all agree that anything, even Cessation of Existence, would be better than being forced to serve him.
• Despotism Justifies the Means: It's outright stated that all he wants is to conquer The Multiverse and rule over all worlds as their king. Considering the fact that his minions leave at least two human cities in ruin, and the fact that in Act VI chapter 38, before Complica's Reset Button attempt, he gives the vanguard of his army free reign to Rape, Pillage, and Burn to their heart's content, it's very clear that he doesn't care what condition the worlds he conquers are in as long as he's the one ruling them.

Discord

Fairy Tale's ultimate weapon, a Blackheart-enhanced chronofly meant to replace Alucard as the ultimate destroyer, but under Gyokuro's control. First introduced in the final chapter of Act VI, Act VII reveals that once completed, Discord will rage out of control and destroy all of reality.

Initially appearing to be a clone of Luna, similar to the Evil Knockoffs of Moka, Kurumu, Mizore, Ruby, Yukari, and Kokoa, the side story Time and Wisdom, A Rosario Vampire: Brightest Darkness Side Act reveals that Discord is actually a being from an Alternate Universe, befriended by Complica after she became an anomaly.

• The Dreaded: In Act VI chapter 53, it's revealed that all the Fairy Tale scientists are terrified of Discord, their own creation, and are making sure not to rush her creation, fearing they'd be unable to stop it or control it even with an Explosive Leash implanted in her body. As it turns out, that's exactly the kind of reaction Gyokuro was hoping for.
• Person of Mass Destruction: Gyokuro specifically created her to replace Alucard as the new destroyer, one under Fairy Tale's control. It works a little too well; Act VII chapter 3 reveals that upon her awakening in seven days' time, Discord will destroy the entire universe.
