Characters / Rosario Vampire: Brightest Darkness - Non-OCs

The non-Original characters featured in Rosario Vampire: Brightest Darkness, characters featured in the original manga and anime, as well as in the video games.

---

Tsukune Aono

• Adaptational Villainy: In canon, his ghoul form was depicted as simply being a mindless, instinctive Berserker. Here, it's a full-fledged Superpowered Evil Side with its own identity and personality.
• Alternate Identity Amnesia: In Acts II and III, he typically blacks out and has no idea of what happened when the ghoul is in control.
• And Show It to You: In the final chapter of Act III, Ghoul!Tsukune rips several of Kiria's organs out with his bare hands.
• Batman Gambit: His inner ghoul combines this with Love Makes You Dumb in Act II; by exploiting Kokoa's newfound feelings for Tsukune, it successfully manipulates her into giving it enough power from her overcharge to become a full-fledged ghoul and take over Tsukune's body completely, and Kokoa is too blinded by said feelings for Tsukune to notice anything suspicious until it's too late.
• Convenient Terminal Illness: During the final chapter of Act III, Tsukune, already about to die as a result of the cost of the Chrono Displacement spell, deliberately tears off the Holy Lock and unleashes the ghoul, which butchers Kiria. However, as the ghoul had its own mind and personality, it is destroyed instead, leaving Tsukune alive and free of its influence.
• Enemy Within: His ghoul form throughout Acts II and III.
• Evil Laugh: His ghoul form often lets one out.
• Fatal Flaw: His capacity to forgive, according to his friends. In Act IV, Gin states outright that he's "too damn forgiving for his own good," and Dark remarks that it's going to be the death of him someday.
• Rage Breaking Point:
  • In Act III chapter 42, after the deaths of Apoch and Astreal, as well as The Reveal that Hokuto and Jovian were Evil All Along and that they enslaved Felucia and orchestrated Kuyou's attack on Yokai Academy, Tsukune hits it big-time and proceeds to blow Kuyou away in an Unstoppable Rage.
  • In Act IV chapter 28, Tsukune hits it once again with Hokuto; Hokuto had kidnapped and threatened his family, brainwashed Felucia, set Kuyou loose on Yokai Academy, and just stabbed Moka and thrown her off of his airship right in front of Tsukune himself, so Tsukune is understandably furious, even outright telling Hokuto after becoming a full-fledged vampire in chapter 31 that he will never forgive him before beating the ever-loving shit out of him.
• Restraining Bolt: In this continuity, the Holy Lock is an angel-designed device that is specifically meant to suppress his ghoul side completely rather than adapt his body to it.
• This Is Unforgivable!: Tsukune is an All-Loving Hero who is always willing to Turn the Other Cheek, so it takes a lot when he reaches the point that they can't be forgiven. In Act IV, Hokuto has long since crossed the line, and Tsukune flat-out tells him to his face that he will never forgive him for what he's done before beating him senseless.
• Too Dumb to Live: In Act III chapter 8, he insists on trying to peacefully talk to Dark despite Dark having repeatedly threatened to kill him if he doesn't keep his distance.
• Turn the Other Cheek: As lampshaded by Rason and a few others, Tsukune has a habit of making friends with people who try to kill him.
• Unwanted Harem: Played straight initially, but Yukari, Kurumu, Mizore, and Ruby gradually move on as the series continues.
• Vampires Are Sex Gods: When his monster aura is flared up enough, females all around him who can sense it actually orgasm and writhe on the floor in ecstasy.

Moka Akashiya

• Love Makes You Dumb: Outer Moka falls into it in Act III. When she finds out that Hokuto's associate Jovian can apparently repair Tsukune's Holy Lock, Moka is utterly lost in bliss over having Tsukune back to normal and being able to use his power both in battle and in lovemaking, to the extent that she pays no mind to her inner self's protests and insistence that something seems suspicious over the whole thing, especially since Rason claimed that the Holy Lock is one of a kind and that only the Almighty Himself could actually repair it. It isn't until chapter 32, when Ruby makes those exact same points to the entire group, that Outer Moka actually begins considering those facts.
• Took a Level in Badass: As the fic continues, Outer Moka learns to consciously access her power even with the rosary on.
• Trademark Favorite Food: Tsukune's blood, as usual.
• Unwitting Instigator of Doom: While Kokoa is responsible for Tsukune manifesting an inner ghoul due to her failure to perform a blood transfusion properly at the end of Act I, it's because of Moka that the transfusion in question was needed in the first place; while sleeping in his room with him, she sucked his blood dry and nearly killed him in her sleep.

Kurumu Kurono

• Alliterative Name: Kurumu Kurono.
• Ambiguously Bi: She claims Rason as her Destined One, but in Act VI chapter 36, she's a little too eager to fondle Apoch and Astreal's breasts to determine which sister has the bigger bust size.
• Divine Parentage: She's the daughter of the Lord of Hell.
• Female Angel, Male Demon: Inverted; she's a succubus, Rason's a male angel.
• Interspecies Romance: As stated above, she's a succubus, Rason's an angel.
• Never My Fault: In Act VI chapter 44, she quickly lambasts Kokoa for leaving Sun comatose, disregarding the fact that, even if Kokoa did get carried away, it was Kurumu's own teasing about seeing her have sex with Werewolf!Gin, and the fact that she told her that Sun was spying on her the whole time, that set Kokoa off in the first place.
• Rerouted from Heaven: A variation in Act V. After Rason, mind-controlled by the Otonashi sisters, breaks up with her, Kurumu succumbs to Death by Despair and ends up in Hell; the Lord of Hell explicitly states that he drew her soul to Hell before it could go to Heaven. Rather than torture her, however, he wanted to knock some sense into her, having been revealed back in Act II to be Kurumu's biological father. Through his efforts, Kurumu unlocks a new Super Mode, and the Lord of Hell sends her back to Earth to reclaim her man.
• Sex Is Violence: In Act V, Kurumu gains a Super Mode, physically presented by her wings, tail, and claws being enveloped in purple fire, that makes her powerful enough to go toe-to-toe with Tsukune after his Restraining Bolt has been removed. However, her sex drive increases in proportion to her strength, and if it goes on for too long, she'll try to get it on with anyone (while she prefers Rason when it gets to that point, she's also tried to force herself on Rin and Sun).
• Super Mode: Gets one in Act V.
• Technicolor Fire: When in her Super Mode, her wings, tail, and claws are engulfed in purple flames.

Mizore Shirayuki

• Armor-Piercing Question: In Act VI chapter 48, she, getting tired of Arial's blatant favoritism of Felucia over her, asks how she can get on Arial's good side, to which Fang Fang suggests that Mizore just needs to be nicer to her, leading to this:
  Mizore: I've been on my best behavior with her. I even saved her ungrateful soul's life earlier. How can I possibly be nicer to her?
  [Fang Fang tries to come up with a suitable answer, but cannot]
  Mizore: Yeah, exactly.
• Bait-and-Switch: In Act I chapter 4, Mizore has a Freak Out and attacks Moka in a rage, fully intending to Murder the Hypotenuse. When she goes in for the final blow and seemingly impales Moka with her ice claws, her fury fades and she is instantly horrified at what she did, making it seem that she came to her senses and regrets attacking her friend. Then it's revealed that she actually impaled Tsukune, who had jumped in the path of Mizore's attack to save Moka.
• Defiled Forever: She believes herself as such after Miyabi rapes her in Act II, to the extent that she attempts suicide. Kurumu talks some sense into her.
• Green-Eyed Monster: In Act I, she gets so jealous of Tsukune's attention to Moka that she actually attacks the latter.
• Ideal Illness Immunity: As she tells Yukari in Act I, despite constantly sneezing, she cannot catch colds.
• Murder the Hypotenuse: She of all people attacks Moka and tries to do this to her in a rage in Act I; Tsukune's Taking the Bullet for Moka snaps her out of it.
• Sexual Extortion: In Act II, Miyabi forces Mizore to have sex with him in exchange for her mother's life, unaware that Miyabi never intended to honor his end of the bargain.
• Shooting Superman: On multiple occasions, she tries to use her powers on fire-based opponents, only for them to No-Sell it. Kuyou even lampshades it in Act III chapter 42, stating outright that she should know by now that her powers won't affect him.

Yukari Sendo

• Green-Eyed Epiphany: She spends several chapters of Act III jealous of Ahakon's relationship with Apoch and Astreal, but repeatedly denies it, insisting that she doesn't care. Eventually, she realizes she does care, and has fallen in love with Ahakon.

Ruby Tojo

• Innocently Insensitive: In Act III chapter 7, she tells the newly-resurrected Apoch and Astreal how Fairy Tale had raped and sexually abused the Clone Army of them they had made to the last detail because she believed it made said clones' subsequent Roaring Rampage of Revenge more poignant. The Ezranas are understandably traumatized, and the others take the time to tell Ruby that she really didn't have to tell them that.
• It Was a Gift: From the end of Act III onwards, she wears a black rose in her hair, gifted to her by her new love interest Razico.

Kokoa Shuzen

• Adaptational Badass: In Act II at the Snow Village Kokoa drinks blood from a very powerful warlock. This causes her to develops an ability called “overcharge” in chapter 28 in which she increases her demonic aura (which increases her strength and other powers) immensely. When it first manifests, Inner Moka not only fails to get a hit in, but Kokoa actually manages to HIT HER, something that never happened in the manga or anime.
  • In IV chapter 20, when testing her ability and consciously overcharges for a time they find that not only is it happening faster, but she reaches such an incredible power level that even Inner Moka is intimidated and acknowledges that if she were to punch her in that state Kokoa would turn her to dust.
• Aesop Amnesia: In Act I, she's single-mindedly attracted to Dark despite the fact that he's only interested in Mizore, and it's only after Dark explicitly tells her to her face that he has no interest in her, along with the realization that chasing after him has negatively affected her pride, which Kokoa constantly boasts about, that Kokoa realizes her mistake and backs off. Come Act II, she's completely forgotten this lesson and goes so far as to invoke a sacred vampire pact, punishable by death if broken, with Moka in an attempt to have Tsukune to herself; the others even point out how pathetic it is that Kokoa didn't learn her lesson in not chasing after boys who are already taken the first time. When Kokoa loses the pact, and subsequently realizes that Tsukune only loves Moka and what she would have taken from him had she won, she finally seems to learn her lesson, and this time, it actually sticks.
• Ain't Too Proud to Beg: In Act I chapter 20, she begs Dark not to reject her; Inner Moka is quick to call her out on it, remarking that after all her talk about vampire pride, Kokoa is still stooping as low as to beg a boy who is already taken for his love.
• The Atoner: In Act III, because she was responsible for the ghoul managing to get enough power to hijack Tsukune's body completely, Kokoa swears fealty to Tsukune in atonement.
• Awesome, but Impractical: Her overcharge grants her enough power to go toe-to-toe with Inner Moka, but even the slightest attack completely depletes her energy, and if she doesn't use it up, it can lead to a Superpower Meltdown.
• Ax-Crazy: While Kokoa has always had a Hair-Trigger Temper, she dips into this during Act VI chapter 44, becoming so enraged at Sun for hounding Gin that she punches her through a wall, chases Felucia and Sun through the Huangs' villa while attacking them in a blind rage, and finally has to be chained up by her friends while she growls and snaps at them like a vicious dog. Even before then, in chapter 11, she activates her overcharge in a rage that Sun kissed Gin in front of her and tries to kill her, only failing because of Complica; Kurumu and Mizore openly admit they're not surprised that Kokoa would go that far.
• The Berserker: She has serious rage issues, which reach a head in Act VI chapter 46 when she discovers Sun spied on her and Gin making love and Sun stupidly pushes her to her Rage Breaking Point by telling her that she's not worthy of Gin at all; Kokoa promptly flies off the handle, punches Sun through a wall, and then chases Felucia and Sun through the halls of Fang Fang's home, attacking them in a blind rage. Arial has to freeze her solid to get her to stop, and even then, the others have to chain her in place to stop her from going after Sun any more, all while she growls and snaps at them like a rabid dog. Kokoa is subsequently horrified when she discovers that her attack on Sun left her with a fractured skull, ruptured her eyes, and left her essentially brain dead, and while she swears that she didn't mean to hurt Sun that badly, the others point out that Kokoa's rage-fueled, violent actions beforehand speak differently.
• Burning with Anger: She hits this territory in Act VI chapter 42. Having discovered that Sun had spied on her and Gin having sex, Kokoa activates her overcharge while ranting at Sun over why she just can't get it through her head that Gin doesn't love her like that anymore. She hits her Rage Breaking Point when Sun proceeds to tell her that Kokoa doesn't deserve Gin at all; at that point, Kokoa snaps, punches Sun through the wall, and when Felucia grabs Sun and helps her escape, Kokoa chases her through the halls with intent to kill.
• Character Development: Over the course of the fic, she goes from a disrespectful, bitchy Bratty Half-Pint who treats everyone except Inner Moka like crap to a Jerk with a Heart of Gold who finally accepts Outer Moka as her sister and is all around nicer to everyone else. Then there's her attitude towards Sun in Act VI. At first, she's so furious at Sun for kissing Gin that she suggests they sacrifice Sun to reconstruct Mizore's body for kissing Gin, stating outright she deserves to die for it, and also openly suggests that they trade Sun to Babylon, essentially forcing Sun into a live of slavery to a crazed Multiversal Conqueror, to get Luna back, stating it's a "fair trade," before physically attacking Sun with intent to kill. By the time of chapter 44, when she and Sun get in a fight over Gin that ends with her landing Sun in the infirmary with a fractured skull and essentially being brain dead, Kokoa is horrified and swears up and down she never meant to go that far.
• Love Makes You Dumb: In the latter chapters of Act II, she's so blinded by her newfound love for Tsukune that she doesn't realize that his inner ghoul is influencing his actions in order to manipulate her into finishing the transfusion and give him a power surge from her overcharge until it's too late. When she finds out, Kokoa is so devastated by her mistake and ashamed that she was so easily tricked that she nearly commits suicide.
• Unwitting Instigator of Doom: The entire Ghoul!Tsukune subplot in Acts II and III occurred because Kokoa failed to perform a vampire blood transfusion to save his life at the end of Act I properly.
• Yandere: In Act III chapters 11 and 12, Kokoa, having been infected by Tsukune's inner ghoul, develops a darker side that is this to Tsukune, wanting nothing but to make love to Tsukune whether the latter wants it or not; indeed, as soon as Moka leaves the room and said dark side takes over, Kokoa goes so far as to paralyze Tsukune with a "love tap" to the spine just to ensure he'll hold still while she has her way with him.

Koumori Nazo

• Explain, Explain... Oh, Crap!: In Act III chapter 46, after dismissing the possibility that Akua and Kahlua are Fairy Tale agents, Kou proceeds to explain to the headmaster that the Chrono Displacement spell that Fairy Tale stole from the Shuzen estate was stored in a secret archive that only Issa and his daughters knew about. As soon as those words are out of his mouth, Kou realizes that the only way Fairy Tale could possibly have known about the archive, let alone the spell, is if Akua and Kahlua were working for them.
• Lawful Stupid: In spite of his loyalty to Kokoa, the minute he finds out that she violated the Eia Dreahl pact she made with Moka, punishable by death if broken, he immediately runs off to tell Issa as such, uncaring that Kokoa was possessed when she forced herself on Tsukune. Both Kokoa and Moka state outright that regardless of whether or not Kokoa was in control of herself at the time, it doesn't matter: she broke the pact either way. He only relents after Dark exploits a loophole in the pact to get her off the hook.

Fang Fang Huang

• Didn't Think This Through: In Act VI chapter 22, to deal the finishing blow to a monster Ceal had grounded, Fang Fang summons a phoenix, forgetting that he's doing so in the middle of his own backyard, the phoenix is powerful enough to incinerate his entire compound, and there are several people right in the middle of its blast radius. When Ceal points this out, Fang Fang's only response is a sheepish "Oh, right."
• Genre Savvy: In Act VI chapter 10, Fang Fang explains that when he registered as a monster with the HDA, he told them that he lived in China, not Japan; thus, he has an entire villa that the gang can hide out in, and the HDA will never think to look for them there.
• Neighbourhood-Friendly Gangsters: He's part of the Chinese mafia, but he and his family are quite a friendly bunch, Felucia admitting she trusts him completely. Fang Fang even tells the group that, while they are a mob family, all of their dealings are legit.

Ginei Morioka

• Adaptational Relationship Overhaul: In the Manga he enters a relationship with San, here he enters a relationship with Kokoa (rather than her hooking up with Haiji)
• Bigger Is Better in Bed/Gag Penis: In Act VI chapter 41, Gin's penis in werewolf form is said to be so big that both Kurumu and Ran are shocked at how Kokoa can handle it without lubricant.
• Can't Act Perverted Toward a Love Interest: He starts to shape up in Act III after becoming Kokoa's boyfriend.

Akua Shuzen

• Adaptation Species Change: In canon, she was a pure-blooded vampire. Here, she becomes a Hybrid Monster after transfusing herself with Alucard's blood.
• Adaptational Heroism: She's given a more sympathetic motive for joining Fairy Tale (wanting to put her father on the top of the world) and pulls a Heel–Face Turn when she discovers Kiria's plan would have included killing Issa.
• Adaptational Wimp: Downplayed; while she lacks the Jigen-Tou and is thus not the threat she was in the manga, she nonetheless remains a powerful and competent enough fighter to easily beat both Tsukune and Inner Moka at once with ease.
• Humans Are the Real Monsters: Is a firm believer in this at first. She gets better.
  Akua: Share the earth? With humans? All they do is squabble over everything they can. You've seen how they spread over the world like a disease. I don't understand why you would want to coexist with them when they are more barbaric than most monsters.
• Not What I Signed on For:In Act III, she and Kahlua joined up with Fairy Tale and help Kiria in his plan with the intent to make Issa one of the top dark lords once humanity is subjugated. They have this reaction when they discover in chapter 52 that Kiria didn't just plan on using the Chrono Displacement spell to send Ghoul!Tsukune back to the Battle of Kahdaln and rewrite history in favor of the monsters: he also planned on using it to send Blackheart-enhanced monsters out to wipe out the dark lords and all of the other powerful beings of their time, thus ensuring that Kiria would be the top monster in the new timeline, and that he would have infected Akua and Kahlua with Blackheart and sent them back to kill their father as part of it.
• Restored My Faith in Humanity: Though she no longer works for Fairy Tale as of Act IV, Akua still believes that Humans Are the Real Monsters and can't understand why Moka and other monsters would want to co-exist with them. Spending time with Tsukune and the others gets her to change her mind, leading to her rescuing a human boy from death during the climax of the act; by the time of Act V, she's become an advocate of co-existence.

Kahlua Shuzen

• Adaptation Species Change: Like Akua, she became a Hybrid Monster after transfusing herself with Alucard's blood.
• Attention Deficit... Ooh, Shiny!: In Act IV, while discussing his plan to use Akua as their "Tsukune detector," Dark explains that Akua is the only one who can do so because Moka is still badly injured, Kokoa would pass out from the force of Tsukune's aura before they manage to get a solid reading, and Kahlua is absentmindedly looking off in the distance while he's explaining all this.
• Blade Below the Shoulder: She can morph one arm into a blade as a result of her infusion with Alucard's blood. As shown in Act IV chapter 27, her blade is durable enough to block one of Jovian's Hand Blasts, though not without causing her pain.
• Not What I Signed on For: In Act III, she and Akua joined up with Fairy Tale and help Kiria in his plan with the intent to make Issa one of the top dark lords once humanity is subjugated. They have this reaction when they discover in chapter 52 that Kiria didn't just plan on using the Chrono Displacement spell to send Ghoul!Tsukune back to the Battle of Kahdaln and rewrite history in favor of the monsters: he also planned on using it to send Blackheart-enhanced monsters out to wipe out the dark lords and all of the other powerful beings of their time, thus ensuring that Kiria would be the top monster in the new timeline, and that he would have infected Akua and Kahlua with Blackheart and sent them back to kill their father as part of it.
• Psychopathic Manchild: She retains this trait even after her Heel–Face Turn. Despite being the second oldest of the Shuzen sisters, she often acts like a young child, doing such things like whining and watching cartoons. It's also explicitly noted by other characters that every time Kahlua cries, she throws a temper tantrum; one such tantrum in Act IV chapter 2 almost leads to Yukari getting chopped up by her Blade Below the Shoulder. Later, at Tsukune's house, she ends up whining about a Potty Emergency.

Sun Otonashi

• Adaptational Name Change: In the manga her name is San, not Sun.
• Adaptational Jerkass: In the manga she's a sweet girl who reciprocates Ginei's feelings for her.
• Date Peepers: In Act VI chapter 41, she spies on Kokoa and Gin having sex. When Kokoa finds out next chapter... let's just say she doesn't take it well.
• Entitled to Have You: In Act VI,despite having previously spurned Gin's Love Confession, and this being the first time she's seen him in years, Sun now relentlessly pursues Gin, uncaring that he's since moved on to Kokoa, and goes so far as to spy on them having sex. It isn't until her actions drive Kokoa to nearly kill her in a fit of rage, and Gin finally puts his foot down that they'll only ever be Just Friends due to his relationship with Kokoa, that Sun finally stops and drops this mindset.
• Friend to All Children: She easily befriends and bonds with Arial and Complica in Acts V and VI. In Act VI chapter 22, it's the sight of Sun saving the two from Babylon's monsters that convinces Ran that Sun wasn't the one who destroyed their hometown.
• It's All About Me: She counts to an extent during Act VI. Despite having previously spurned Gin's Love Confession, and despite this being the first time they've even seen each other in years, Sun still fully expects that Gin will come back to her, uncaring that he's since moved on to Kokoa. Moka even takes the time to call her out on it in Act VI chapter 20. It's only after Sun pisses off Kokoa to the extent that the latter beats her into a coma, and after she comes out of said coma, that she finally grows out of it.
• MacGuffin Super-Person: From Act V onwards, Babylon seeks to capture Sun and force her to use her siren powers to enslave powerful monsters, as Sun, unlike most other sirens, can charm both male and female monsters.
• Silent Snarker: She pulls this off, writing down quite a few zingers on her sketchpad. Best shown in this exchange between herself and Kokoa in Act VI chapter 17:
  Kokoa: If you so much as touch him, if you even try to undress him with your eyes, I will beat you into a bloody smear on the ground! Do you hear me?!
  Sun: [writing] If I really wanted to steal Gin away from you, I'd just charm him into loving me and charm you into jumping into a river. And for the record, who can't hear you when you're screaming all the time?
• Too Dumb to Live: In Act VI chapter 42, when Kokoa finds out Sun spied on her and Gin having sex, Sun doesn't seem to understand that she's only making things infinitely worse for herself by telling an already pissed off Kokoa that she doesn't deserve Gin at all. She doesn't stop even as Kokoa is supercharging herself; it comes as no surprise when Kokoa puts her through the wall before chasing her and Felucia through Fang Fang's villa in a homicidal rage.

Kuyou

• Adaptational Karma: In canon, he survived the final battle with Alucard and went on to rebuild Fairy Tale. Here, he's killed off by Tsukune in Act III, and the final chapter of Act IV shows him in Hell being tortured for his crimes.
• And Your Little Dog, Too!: In Act III chapter 41, Kuyou states that, while he did come back to Yokai Academy for revenge on Tsukune, he also plans to kill everyone else there because he finds the idea of human/monster coexistence disgusting. Sure enough, the very first thing he does upon arriving is incinerate Astreal, who had never even met him and had nothing to do with his past, For the Evulz.
• Believing Their Own Lies: During his attack, he declares with complete conviction that he used to protect those at Yokai Academy and tried to guide them. Of course, everyone at Yokai Academy knows that he's nothing but a super-powered bully and human-hating Knight Templar who abused his authority as head of the Student Police to make everyone at the school miserable.
• Big Bad Wannabe: He's hyped up as a dangerous menace throughout Act III, but while he has gotten much stronger by the time of his return, he's ultimately nothing more than Hokuto's stooge, and the minute Tsukune gets angry enough and jumps into the fray, Kuyou is completely outclassed and ends up losing his head, even after going One-Winged Angel.
• Demoted to Extra: He goes from an operative of Fairy Tale to a generic human-hating thug whose only purpose in the plot is to serve as Hokuto's Unwitting Pawn and then get killed off by Tsukune.
• Evil Cannot Comprehend Good: In Act III chapter 41, he accuses Ms. Nekonome of poisoning the students with "garbage" about coexisting with humans. Ms. Nekonome retorts that she's teaching them how to live peacefully and not start wars, a lesson that Kuyou is obviously incapable of learning.
• Faux Affably Evil: Dips into this after burning Astreal to death, literally right after she said she'd rather die than kiss Jovian again.
  Kuyou: Well, she did ask for it. And I'm such a gentleman, how could I not grant her request?
• I Am Not Left-Handed: In Act III chapters 41 and 42, the gang (minus Tsukune) is doing relatively well against Kuyou at first, but only because, as Moka points out, Kuyou hasn't even been trying. Sure enough, Kuyou goes One-Winged Angel soon after Moka says this and makes short work of everyone... until Tsukune reenters the fray and annihilates him.
• Ironic Hell: One of the last crimes he committed in life was murdering Kenzo, one of Dark and Felucia's friends, and his entire gang on Hokuto's orders. When he's shown in Hell at the end of Act IV, Kenzo is among those torturing him.
• Insane Troll Logic: In Act III chapter 41, he goes on a rant towards the other students about how he tried to protect and guide them; of course this falls completely flat considering the fact that he ran the Security Committee like a yakuza group, made the other students' lives miserable, killed more than one of them in cold blood, and generally did the exact opposite of protecting and guiding the students.
• Misplaced Retribution: Upon discovering that Kuyou is coming back to Yokai Academy to kill Tsukune in revenge for his previous defeat, the others are confused because it was Moka who defeated him. Tsukune theorizes that it's because he's living proof that humans and monsters can co-exist, and Kuyou, being the anti-human extremist that he is, is disgusted by that.
• Pitiful Worms: During his Insane Troll Logic rant, he openly declares humans the equivalents of ants and dirt.
• Speak Ill of the Dead: In Act III chapter 41, he mocks Kenzo's death to Dark's face, remarking that he "wasn't much of a fighter" and calling him a "foolish old man."
• Unwitting Pawn: In Act III chapter 42, it's revealed that Hokuto lured him to Yokai Academy by exploiting his desire for revenge on Tsukune and his friends, using the chaos to his advantage to steal the artifact he needed for his plan.
• The Worf Effect: He's trained and grown stronger in the intervening time since the Newspaper Club defeated him, and the minute he goes One-Winged Angel, he turns the tables on the entire team in moments. Then Tsukune reenters the fray, No Sells Kuyou's fire attacks, and effortlessly beats him into the ground before putting his fist through Kuyou's head.
• Your Head Asplode: He meets his demise this way, courtesy of Tsukune and a Megaton Punch.

Ms. Nekonome

• Badass Teacher: In Act III chapter 41, she bravely stands up to Kuyou of all people, reminding him that he is no longer welcome at Yokai Academy and ordering him to Get Out!. While she does lose some of her bravado when Kuyou draws his sword and comes after her, just the simple fact that she's willing to stand up to an anti-human Knight Templar who needs very little provocation to reduce humans and monsters alike to smoldering piles of ash in the first place qualifies her for this.

Kiria Yoshii

• Adaptational Karma: In the original manga, he survived the final battle and went on to rebuild Fairy Tale. Here, he's killed off by the end of Act III, with the final chapter of Act IV showing him in Hell being tortured for his crimes.
• Admiring the Abomination: In Act III chapter 52, when Tsukune unleashes the ghoul, Kiria takes the time to remark how magnificent it is. All that admiration goes out the window, however, when the ghoul pounces on him and literally tears him to pieces with his bare hands rather than help Kiria with his plan.
• Bad Boss: He has quite the disregard for his own troops. In Act II chapter 25, he deliberately stands by and watches as Dark fights and kills Miyabi, even personally helping Dark by giving him a sword while deeming Miyabi's death a "necessary sacrifice." Furthermore, a significant chunk of his plan in Act III involves infecting most of his troops with Blackheart, a Psycho Serum that drives those who take it insane and kills them after one hour.
• Be Careful What You Wish For: Throughout Act III, Kiria had hoped to unleash Tsukune's ghoul form for his plans. In the final chapter of Act III, Tsukune, about to die anyway as a result of the cost of using Chrono Displacement, deliberately removes the Holy Lock and unleashes the ghoul, which promptly tears Kiria apart.
  Rason: He gave Kiria what he wanted after all... he made sure the bastard wouldn't survive.
• Evil Is Not a Toy: He hoped to harness Tsukune's inner ghoul, planning to infect it with Blackheart and sent back in time to the Battle of Kahdaln to rewrite history in favor of the monsters. In the final chapter of Act III, when Tsukune deliberately unleashes it, the ghoul promptly pounces on Kiria and both dismembers and disembowels him with his bare hands while Kiria tries in vain to reason with it.
• In Their Own Image: In Act III, this is what hiss plan ultimately boils down to: by using the Chrono Displacement spell and the Blackheart serum, he plans to change the outcome of the Battle of Kahdaln, which forced the monsters to set up The Masquerade in the first place, in favor of the monsters using Tsukune's inner ghoul, as well as use other Blackheart-infected monsters to wipe out all of the Dark Lords and any other powerful beings who could possibly pose a threat to him, effectively creating a world where monsters rule, humanity is extinct, and Kiria himself is the greatest, most powerful monster of them all. Unfortunately for Kiria, the plan fails, and he ends up dead because, in the case of Ghoul!Tsukune, Evil Is Not a Toy.
• Not-So-Well-Intentioned Extremist: His plan in Act III involves using Chrono Displacement to rewrite history. While Akua and Kahlua believe that he just planned to change the outcome of the Battle of Kahdaln, which forced the monsters to set up The Masquerade in the first place, in favor of the monsters using Tsukune's inner ghoul, creating a world where monsters reign supreme and they wouldn't be confined to the monster world, which would give their father a high ranking position. In the final chapter, Tsukune and the others deduce by the massive amounts of Blackheart that Kiria has at the ready for his plan, as well as his intent to duplicate the Chrono Displacement spell, that Kiria planned to do far more than that; he in fact planned to send out multiple Blackheart-infected monsters to wipe out all of the Dark Lords and any other powerful being who could pose any threat to him, remaking history in his own image.
• Rasputinian Death: He actually manages to stay alive and fully conscious after Ghoul!Tsukune rips off his arms and tears out most of his internal organs, as well as a chunk of his spine. He finally dies after Ghoul!Tsukune crushes his skull.
• Villains Out Shopping: He may be a crazed, Nazi-esque terrorist, but Kiria still enjoys reading manga. According to Hokuto, his plan to Time Travel for Fun and Profit was gotten from manga.
• We Have Reserves: His plan in Act III, which involved infecting dozens, if not hundreds, of his agents with Blackheart and then sending them back in time. Between Blackheart's one-hour time limit before it kills the infected and the life-stealing cost of Chrono Displacement after twenty-four hours, those minions were doomed no matter what.

Hokuto Kaneshiro

• Adaptational Karma: In the original manga, he survived the final battle with Alucard and went on to rebuild Fairy Tale. Here, he's killed during the climax of Act IV, with the final chapter of Act IV specifically showing him being brutally tortured in Hell.
• Adaptational Villainy: Though Hokuto was always an antagonist in the manga, he was more of a Wild Card to the extent that he helped Tsukune and Moka stop his own plan. Here, he's a straight-up no-gray-area villain and a blatant Straw Nihilist who openly expresses the view that life itself is nothing but a meaningless plague that must be wiped out.
• The Bad Guy Wins: During the climax of Act IV, he, as part of his plan, deliberately breaks The Masquerade to the entire human world in order to prove to Moka that humans and monsters could never possibly co-exist. It takes some time, but soon the entire human world becomes afraid of monsters. Ultimately subverted by the end of Act VI.
• Batman Gambit: In Act III, his plan to use Kuyou as a distraction while he steals the Artifact of Doom he needs for his plans from Yokai Academy's archives hinged solely on Kuyou's desire for revenge on Tsukune. It works like a charm.
• Benevolent Boss: For all of his flaws and insanity in Acts III and IV, he does treat Jovian and Jacqueline decently and with respect.
• By "No", I Mean "Yes": In Act III chapter 41, Hokuto takes the time to watch the carnage Kuyou is inflicting on the academy. When Felucia asks him if that's how he gets his kicks, Hokuto responds:
  Hokuto: Hardly, but I'm not against enjoying the moment.
• Death by Adaptation: In the original manga, he survived the final battle. Here, he's dead by the climax of Act IV.
• Dirty Coward: In Act IV, the gang accuses him of being one on multiple occasions, and it's somewhat justified; among other things, Hokuto has held Felucia and Tsukune's family hostage to use their lives as leverage against the group, and typically lets Jovian and Jacqueline, as well as his other mooks, do the fighting for him while he makes a Villain: Exit, Stage Left. The only time he actually fights on his own is when Tsukune corners him at Alucard's tomb during the climax of Act IV, during which he proves to be quite the badass when pushed.
• Evil Cannot Comprehend Good: As a Straw Nihilist, he's completely incapable of believing that humans and monsters could ever peacefully co-exist, and even deliberately breaks The Masquerade to prove to Moka that the humans would never accept monsters. He's firmly convinced that the humans in Tsukune's neighborhood will kill Tsukune and his friends without even trying to listen to reason, and is absolutely surprised when the group actually manages to win said humans' trust, with Moka even taking the time to rub it in his face. Of course, it doesn't stop Hokuto from going on with his plan.
  Moka: Off to prove another failed hypothesis, Hokuto?
  Hokuto: Don't think this changes anything, Moka. Your friend may have persuaded his dear old mother and some frightened people to hold their fire, but by the looks and sounds of it down below the human race isn't exactly welcoming the monster world with open arms. Tsukune hasn't proven anything other than he can use fear and confusion to slip out of danger.
• Faux Affably Evil: He constantly acts polite and refined, even while committing all manner of horrible atrocities and declaring that life itself is a plague that needs to be wiped out.
• Final Solution: He's firmly convinced that all life forms, human and monster alike, are equally evil and will endlessly kill each other simply to continue living for the sake of living; thus, he seeks to achieve peace by resurrecting the ancient destroyer Alucard and allowing him to kill every last living soul on the planet.
• Hates Everyone Equally: His motive for resurrecting Alucard. As he states to Moka, he hates all living things, humans and monsters alike, and views them as nothing but evil, meaningless trash who could never co-exist and only want to live for the sake of living, endlessly killing one another to do so; thus, he believes that the only way to achieve true peace in the world is by reviving Alucard and allowing him to destroy every living thing on the planet.
• It Can't Be Helped: In Act III chapter 41, when Jovian asks him what they will do when her repair work on Tsukune's Holy Lock wears off and if the lock breaks completely before he defeats Kuyou, Hokuto simply shrugs, says this trope word-for-word, and goes on to say that all they can really do is hope they can steal the artifact they need from the academy and get away before that happens, and then just wish Tsukune the best of luck.
• Mask of Sanity: While he constantly acts polite and sane, and even manages to win the trust of Tsukune's group, it's revealed that he himself personally arranged for Kuyou to attack the academy so he could steal an Artifact of Doom while the gang was distracted fighting him, needing said artifact to revive Alucard and destroy the world out of the nihilistic view that all live is evil and meaningless. Also, when his Co-Dragons, Jovian and Jacqueline Kikion, are resummoned in Act VI, they state that their morality is shaped by their master; when one considers that the Jovian and Jacqueline under his control were Ax-Crazy Psychopathic Manchildren who committed such atrocities as rape, Cold-Blooded Torture, and wanton mass murder and destruction as a matter of course, it's even more proof of just how off his rocker Hokuto really was.
• Moral Myopia: He holds the nihilistic view that all life, human and monster alike, is naturally evil and violent, with living things destroying everything around them for no good reason. He himself is just as violent and destructive, considering the fact that, among other things, he arranges for Kuyou to attack Yokai Academy, killing numerous innocents and nearly burning the school to the ground, and later directly orders Jovian and Jacqueline to cause as much destruction and death in Tsukune's hometown as possible to force the gang to reveal they are monsters by fighting them, all so he can prove human/monster co-existence is impossible by making Moka watch as her loved ones and friends are killed by the very same humans they'd sworn to protect.
• Not-So-Well-Intentioned Extremist: Throughout Acts III and IV, he states repeatedly that what he's doing is right, declaring that humans and monsters are all equal bastards and that reviving Alucard to destroy every living thing will bring about true peace. Of course, everyone can tell right away is that he's nothing but a crazed, nihilistic sociopath who Hates Everyone Equally.
• Oh, Crap!: In Act IV chapter 27, he's quite shocked when Apoch uses her Laser Blade to cut through Jovian and Jacqueline's barrier, especially since they were hyped up to be completely unbreakable. Hokuto had previously brushed off any and all threats to his life and declarations that they'd stop his plans with a smirk and a chuckle, so this is the first time that anything has taken him by surprise.
• Omnicidal Maniac: The extent of his evil plan is simply to revive Alucard and kick back and watch as he destroys every last living thing on the planet. Why? Because he thinks all living things, human and monster alike, are an evil plague that needs to be wiped out.
• Put Them All Out of My Misery: What his plan ultimately boils down to. He views all life, human and monster alike, as a plague that needs to be wiped out, and thinks the only way to achieve true peace is by resurrecting Alucard and allowing him to bring about The End of the World as We Know It.
• Shut Up, Kirk!: In Act IV chapter 24, Moka insists that his nihilism is unjustified and that both humans and monsters do have good in them, with those at Yokai Academy being proof of that. Hokuto retorts that Yokai Academy simply teaches monsters to survive amongst humanity by hiding what they really are, which is not true coexistence.
• The Sociopath: He's depicted as such here. During his screen time, he effortlessly manipulates Tsukune and his group, fooling them into believing he's on their side until he reveals that he personally orchestrated Kuyou's attack on Yokai Academy as a distraction so he could steal an Artifact of Doom from the school; in the final chapter of Act III, he shows little to no reaction when Kiria, whom he had a Villainous Friendship with, is killed, stating that this simply proves that he was right and Kiria's plan was doomed from the start; if anything, he's happy that Kiria is dead because now he can enact his own Evil Plan as per their deal. On top of it all, the entire extent of his plan is to bring back Alucard and then just sit back and watch as Alucard destroys the planet because he's convinced that all life, human and monster alike, is an evil and meaningless plague that needs to be wiped out.
• Straw Nihilist: In Act IV, he states that both humans and monsters are equal bastards and could never hope to co-exist, hence why he's trying to resurrect Alucard to destroy the world:
  Hokuto: You see, I've seen some truly horrible things in life, Moka. You'd be surprised how similar humans and monsters really are. How they both claim they desire peace, yet both destroy everything around them. How they both claim they can love, yet they both hurt and attack everything different. You see, it doesn't matter if you are human or a monster, a life is a life. And all lives are trash. All lives are a waste. Everything that lives only wants to live for the sake of living, and will step on anything to get its wish. Monsters, humans, they all claw at any vain attempt to live on, both killing anything that seems different or strange in fear of its own existence. There is no difference, Moka. All life is evil.
• This Cannot Be!: Most of Acts III and IV go his way, and he smugly brushes off any and all threats to his life and declarations they'll stop his plan with a Psychotic Smirk and a chuckle. So when the fully-vampirized Tsukune effortlessly blocks his attacks and utterly curb-stomps him, he's absolutely floored. Best summed up by Hokuto's reaction when Tsukune blocks Hokuto's scythe attacks with his bare hands, stopping him cold.
  Hokuto: That's not possible... how did you...
• Villain Has a Point: He may be a crazed, nihilistic Omnicidal Maniac, but Hokuto does make a valid point in Act IV chapter 24 when he tells Moka that Yokai Academy's teachings are more about simply hiding amongst the humans to survive than actually coexisting with them. It's especially poignant since back in chapter 6, Ms. Nekonome made those exact same points, mentioning 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.
• Villainous Legacy: He's dead by the end of Act IV, but his actions leave a shadow throughout the next two acts. Because of him, The Masquerade is broken, and humans now know of monsters everywhere. The next two acts involve Tsukune and co. trying to ensure true peace and co-existence amongst the distrustful humans, and prove Hokuto's nihilism wrong.
• The Worf Effect: He proves to be easily capable of outmatching and fighting Tsukune, even after the latter removes his Power Limiter, before he goes One-Winged Angel. When Tsukune becomes a full vampire thanks to the Shuzen sisters in Act IV chapter 31, Tsukune effortlessly blocks all of his attacks and beats him into the ground.

Tenmei Mikogami

• Adults Are Useless: His general response to any threat amounts to "sit on my ass and do nothing while Tsukune's group risks their lives in my place." Best displayed in Act III chapters 40-44; both Kuyou and a Fairy Tale armada invade and attack Yokai Academy one after the other, and instead of trying to stop them, he sits back and watches as Tsukune's group fights them back in his stead. Even before that, he repeatedly does virtually nothing about the various bullies and Jerkasses who deliberately go out of their way to torment and harass Tsukune and his friends, but punishes Tsukune and co. for simply acting in legitimate self-defense against said bullies and Jerkasses, to the extent that he threatens to separate them if they get into another fight. This, of course, leads to the bullies taking advantage of Mikogami's warning to actively harass them without fear of retribution, eventually leading to Kano blackmailing the girls and nearly raping them; after this, Mikogami, now realizing the masses are targeting Tsukune and co., changes his mind and allows them the right to defend themselves.
• Selective Enforcement: During most of Act III, he repeatedly does next to nothing about the various bullies and Jerkasses who deliberately go out of their way to torment and harass Tsukune and his friends, but punishes Tsukune and co. for simply acting in legitimate self-defense against said bullies and Jerkasses, to the extent that he threatens to separate them if they get into another fight. This case ends up deconstructed in chapters 30 and 31, when the other students take advantage of it to actively harass the gang even more without fear of any retribution, and when Kano uses it to his advantage as well to blackmail the girls into letting him take dirty pictures of them and nearly rape them; Mikogami wises up after the Kano incident and reinstates their right to defend themselves so it doesn't happen again.

Issa Shuzen

• Collector of the Strange: As explained in Act III chapter 46, Issa is a collector of rare magical spells and artifacts, such as the Chrono Displacement spell, though he never actually intends to use them.
• Dramatically Missing the Point: In Act IV chapter 1, when Kokoa and Moka accidentally let it slip that Kokoa turned Tsukune into a ghoul, Issa doesn't particularly care that they managed to save Tsukune and reverse the transformation; he only cares that they didn't kill the ghoul on sight.
• "It" Is Dehumanizing: In Act VI chapter 49, while punishing Akua and Kahlua for not only failing to kill Talon, but letting him set foot in the Shuzen home, Issa outright refers to him as an "abomination" and an "it."
• Lawful Stupid:
  • In Act III chapter 14, after a possessed Kokoa has her way with Tsukune, both Kokoa and Moka state that it doesn't matter whether or not Kokoa was in control of herself at the time; she still mated with Tsukune either way and broke the Eia Dreahl she invoked back in Act II. If Dark hadn't exploited a loophole to get her off the hook, Kokoa would have been executed for something she had no control over.
  • In the first chapter of Act IV, the minute Issa finds out that Kokoa and Moka accidentally turned Tsukune into a ghoul, he starts physically attacking them along with Akua and Kahlua, furious that they didn't do their vampire duty and kill said ghoul on sight while all but openly dismissing the fact that they managed to cure him.
• Parental Obliviousness: In Act III, he was completely oblivious to the fact that Akua and Kahlua had joined Fairy Tale right under his nose, even after they steal the Chrono Displacement spell from his secret archive for the organization's use; said archive was a family secret that only Issa and his daughters knew about, so there was no other way Fairy Tale could possibly have known about it, making it even more ludicrous that he didn't suspect anything.
• Rescue Romance: In Act VI chapter 39, Akasha reveals to Moka that she first met Issa when he saved her from sacrificing herself to seal Alucard away.

Akasha Bloodriver

• Back from the Dead: She was a Posthumous Character for most of the fic up until Act VI, when she's revived and helps protect Luna from Babylon's forces. While it's initially believed she's a disembodied soul like Felucia, Arial, and Complica, Hex reveals in the penultimate episode of Act VI that the Almighty in fact completely resurrected her.
• Refusing Paradise: In Act VI chapter 39, Akasha reveals to Moka that she has been Dead All Along; she was offered a place in Heaven by the Almighty, but refused to accept it because, having been indirectly responsible for Alucard's initial rise to power, she feels she needs to actually earn it.

Gyokuro Shuzen

• Adaptational Jerkass: Gyokuro was a complete and total bitch in the manga, but the fic actually manages to make her even worse. For starters, rather than stay by Issa's side to help raise their children as in canon, Gyokuro straight up abandons the Shuzen family and joins Fairy Tale. Furthermore, in the absence of Alucard's significant canon backstory, there is a strong implication that Gyokuro Shuzen is not only the true leader of Fairy Tale, but its founder as well. If so, she would be ultimately responsible for all the suffering Fairy Tale has caused since Act II.
• Evil Cannot Comprehend Good: As noted in Act VI chapter 53, she's literally incapable of imagining a world where humans and monsters peacefully coexist. To her, humans are a plague, and the very idea of human/monster coexistence is, in her words, a "foolish notion" and a "despicable dream."
• Evil Is Not a Toy: In Act VI, Gyokuro makes a clone of Luna, enhanced with a quadruple overdose of improved Blackheart, named Discord, intending for it to be a new Alucard under her control. As revealed in Act VII chapter 3, when Discord is completed, it will rage out of control and destroy the entire universe.
• Missing Mom: In Act VI chapter 45, Kokoa admits to knowing nothing about Gyokuro, having been abandoned by her shortly after she was born, with the only thing Issa ever told her about Gyokuro is that she was "no longer part of the family," implying that she either left to join Fairy Tale or was cast out of the Shuzen family for collaborating with them.
• Parental Abandonment: Instead of staying by Issa's side to help raise their children like she did in the manga, she up and left altogether, abandoning Kahlua and Kokoa shortly after the latter was born to plot her revenge on Akasha. The most Issa ever told Kokoa about Gyokuro was that she "was no longer part of the family."
• Psychopathic Manchild: As in canon, her entire Evil Plan is essentially just her throwing a temper tantrum over the fact that Issa had been more loving and attentive to Akasha than her.

Alucard

• Adaptational Villainy: The fic does away with the sympathetic backstory that Alucard had in canon completely. In the original manga, Alucard was originally supportive of human/monster co-existence, but turned evil after humans invaded the country he founded for exactly that and killed most of his loved ones. Here, Alucard is depicted as an arrogant, overly powerful vampire, and an Omnicidal Maniac who viewed all living things as a blight upon a world he wanted all to himself. When he's awakened in Act IV, he's devolved into little more than a mindless beast.
• Chrome Champion: He and those infused with his blood are described as having metallic looking flesh.
• Decomposite Character: He and Miyabi Fujisaki are two separate characters, whereas in the manga, Miyabi was Alucard's intelligence in physical form.
• Mook Maker: In Act IV chapter 32, he spawns multiple mini-Alucards to help in his rampage.
• Omnicidal Maniac: As stated in both Acts III and VI, even before he became the monstrous destroyer he is now, Alucard developed a hatred of all life forms, human and monster alike, seeing them as a plague that needed to be wiped out; he even went so far as to turn himself into a monstrous destroyer to this end.

Miyabi Fujisaki

• Adaptational Jerkass: The fic actually manages to make him even worse than he was. In the original manga, he merely groped Mizore and stole her first kiss. Here, he outright rapes her, and has the gall to gloat about doing so right to Tsukune and co.'s faces.
• Asshole Victim: When they find out that he raped Mizore, Dark is so furious that he attacks Miyabi and kills him in the slowest and most brutal manner possible^note In this order, Dark crushes all of the bones in his arms and legs to powder, tears off said limbs one by one, punches Miyabi's jaw clean off, and then finally tears out his spine; despite being horrified at Dark's brutality, Tsukune and the others nonetheless have No Sympathy for Miyabi and unanimously agree that he deserved every second of it.
• An Arm and a Leg: Dark slowly and painfully crushes the bones in his arms and legs to powder with his bare hands, before ripping them clean off.
• Decomposite Character: He's a totally separate being from Alucard in this fic.
• Demoted to Extra: In the original manga, he was originally a clone of Alucard, as well as the Secret Identity of the Masked Man, the true head of Fairy Tale. Here, he's just a generic Fairy Tale agent who's killed off in Act III long before Alucard himself ever shows up.
• Jawbreaker: As part of Dark's Extreme Mêlée Revenge, he punches Miyabi in the face so hard that his jaw snaps right off.
• Loves the Sound of Screaming: In Act II chapter 22, after raping Mizore, Miyabi is vocally disappointed that Mizore didn't scream even once and uses it as a Post-Rape Taunt.
• Rasputinian Death: When Dark has Miyabi at his mercy, he proceeds to, in this order, crush all of the bones in his arms and legs to powder, tear off said limbs one by one, punch Miyabi's jaw clean off, and then finally tear out his spine. Up until the very moment Dark tears out his spine, Miyabi is still alive and conscious.

Ran Otonashi

• Conditioned to Accept Horror: As she reveals in Act V chapter 23, she and her sisters have seen so many horrible things while enslaved to Babylon that the sight of the school grounds littered with blood-drained corpses as a result of Tsukune's rampage doesn't even faze her.
• Compelling Voice: Part of the reason Babylon captured and enslaved her; her voice allowed him to enslave more monsters for his army.

Rin Otonashi

• The Ditz: Due to a spell cast on her mind, she needs to constantly wear headphones to remember anything. It isn't until Jovian and Jacqueline cure her on Talon's orders that her memory returns, and the spell wears off.
• Manchurian Agent: As revealed in Act VI, Falla had Rin's headphones rigged to drive her into a berserker rage whenever she hears heavy metal music. Both times it has happened, Rin ended up destroying her hometown and Yokai Academy.
• Musical Trigger: Falla rigged her headphones, sending her into an Unstoppable Rage and forcing her to destroy everything around her when she hears heavy metal music.
• Revenge Before Reason: She falls into this upon regaining her memories in Act VI. She is well aware that Falla has reformed and helped destroy Alucard, but doesn't care; she still turned her into a Manchurian Agent and caused her to wipe out her hometown and parents. She thus ends up siding with Talon in his crusade, even personally helping him attack Akua and Kahlua despite knowing that they helped save the world. In Act VI chapter 43, Ling Ling even points out that she's just letting her desire for revenge blind her to the fact that she's turning against those who loved and cared for her; befitting this trope, Rin promptly blows her off.

Ren Otonashi

• The Eeyore: Tends to be negative about everything. Best displayed in Act VI; when Tsukune makes it clear he doesn't hate Moka, since her blood transfusions gave her the power to save the world, all Ren can focus on is that Tsukune now has to deal with vampiric bloodlust because of her.
• Yandere: She's turning into one due to her feelings for Tsukune as of Act VI, repeatedly swearing to herself that she'll never let Moka come near Tsukune again to the extent that, in chapter 48, she fantasizes about killing Moka with her bare hands.
