Main Characters Edit

Kinji Touyama Edit

Voiced by: Junji Majima (Japanese) and Todd Haberkorn (English)

Another top student of Assault Side, who, for some reason, demoted himself to the more rear-line Inquest Side. When sexually aroused, he enters a state called "Hysteria Savant Syndrome" (HSS), also known as "Hysteria Mode".

  • The Ace: In HSS mode, he is a smooth talker, has genius level intelligence and is abnormally strong.
  • Affectionate Nickname: Shirayuki's name for him, "Kin-Kin" is meant to be this....
  • Almighty Janitor: Especially in HSS but it's hinted that his normal mode is stronger than the "E rank" would indicate.
  • Anti-Hero: Type II with shades of Type I. For more information, see Knight in Sour Armor.
  • Badass
    • Badass Abnormal: In Hysteria Mode.
    • Badass Normal: He aced the Butei entrance exam and is shown to be highly competent even without Hysteria Mode.
  • Belligerent Sexual Tension: With Aria.
  • Bishonen: A borderline example.
  • Blessed with Suck: Considers Hysteria Savant Syndrome to be this. Sure, it gives him enhanced intelligence, senses, strength and marksmanship, but it also turns him into a Chivalrous Pervert and Insufferable Genius who feels compelled to protect the girl in front of him no matter what, which wouldn't be so bad if he couldn't remember everything he says while it's activated.
  • Bullet Time/Hyper Awareness: One of his powers under HSS.
  • Butt Monkey: In normal mode the girls love to make his life difficult. Generally speaking, he would get the short end of the stick.
  • Chick Magnet: Has Aria, Shirayuki, Riko, and Reki after him. Take note that this is just his primary lineup and he's been ship teased with plenty of other girls.
  • Chivalrous Pervert: While in HSS, he becomes a very smug and smooth-talking ladykiller, and feels compelled to protect any girl in front of him, no matter what. This peeves Kinji to no end.
  • Deus Sex Machina: He needs to be sexually aroused (usually by experiencing Marshmallow Hell or kissing) to activate his HSS.
  • Deadpan Snarker/First-Person Smartass: Snarks a lot in his head.
  • Dual-Wielding: Recent light novel volumes promote him into the "third Quadra", after Aria and Riko.
  • The Dulcinea Effect: The effect of HSS. He has to protect any girl in front of him.
  • First Kiss: With Aria, which also doubles as a deliberate HSS activation to him.
  • Forgiveness: Kinji will always forgive people for their past actions, as shown with Riko, Jeanne and many others.
    • This actually bites him in the ass when he attempts to make peace with his helf-sister Kaname so soon after she had tried to kill his teammates. This causes Aria to view Kinji as a traitor, and the two remain on bad terms for an entire volume.
  • Good Is Not Nice: He may be a Butei, but Kinji isn't a particularly kind or friendly person by any means, even among the people he cares about. And while he'll always forgive people for past actions, that doesn't necessarily mean he's being nice- he simply considers holding grudges to be a waste of time.
  • Harem Hero: His normal mode is Type 1 with shades of Type 2A. His HSS mode is definitely Type 2B.
  • Heroic Self-Deprecation: Often believes he isn't worthy to be the partner of a "winner" like Aria.
  • Humiliation Conga: He was forced to mull leaving Butei after he and his (supposedly-dead) older brother Kinichi was subjected to this after the latter's rescue attempt aboard a sinking ship, but with the shipping company unwilling to take responsibility and instead scapegoating him.
  • I Just Want to Be Normal: At first, he wants nothing more than to quit his life as a Butei and live a normal life, believing his life doesn't have to be special just because he comes from a famous family. From the end of volume 12 onwards, his goal shifts to "I Just Want to Be a Normal Butei", though even that proves to be a challenge.
  • Informed Attribute: Shirayuki states that Kinji's so kind. Riiiight. Then again, this could just be Shirayuki being Shirayuki.
  • Ironic Echo: When Kinji asks Aria why she wants him to work with her, she dodges the question by saying "What makes the sky look blue? How are birds able to fly?" and tells him to figure it out for himself. Later, when she asks what he's doing on her plane back to Britain, he says the exact same lines back to her.
  • Jerk with a Heart of Gold: He's a rude, snarky grump 70% of the time, and a smug womanizer 10%, but there's still definitely a good person inside.
  • Kick the Dog: He has a moment in volume 2/episode 7; being convinced that Durandal is just a myth, he claims that Aria has convinced herself that he's real out of desperation to clear her mother's name. Then, when Aria begs for him to trust her intuition, he takes over guarding Shirayuki by himself and tells Aria to go somewhere and 'cool off'. He later comes to regret this after Shirayuki is taken from right under his nose by the very person he thought was a myth, after which he has the sense to admit that he should have given Aria the benefit of the doubt.
  • Knight in Sour Armor: Most of the time he's just sour, keeping how much he cares about Aria, Shirayuki etc. under layers of bitterness and cynicism. The 'knight' part comes in when he enters Hysteria Mode, when he'll put his life on the line to protect any girl. If only he didn't act so smug while doing it...
  • Lolicon: Regarded by his classmates as one due to his closeness to the diminutive Aria. It also doesn't help that she is the most effective method of triggering his HSS. For example: in Episode 10, Kinji managed to resist HSS from seeing Riko in just her lingerie, but couldn't hold on any longer once he saw Aria taking off her clothes.
  • Mistaken for Gay: By his classmates, since he shows almost no interest in women. He is definitely straight, though.
  • Overshadowed by Awesome: Ironically overshadowed by himself or to be more precise his Hysteria Mode. He himself is aware of this and it's one of the reason's he dislikes Hysteria Mode.
  • Perpetual Frowner: He almost never smiles, and when he does it's usually his way of acting like nothing fishy's going on.
  • Super Mode: His Hysteria Mode. He has a even stronger mode called Berserk Hysteria Mode which is triggered by jealousy.
  • Super Reflexes: One of his Hysteria mode's powers.
  • Tall, Dark and Handsome AND Snarky
  • Thou Shalt Not Kill: He doesn't even like killing wolves.
  • Tsundere: A rare male example. He usually treats Aria with indifference but there are times when he is kind to her. Fittingly, he also fits the original archetype- he warms up to Aria after initially hating her.
  • Unwanted Harem
  • Used to Be a Sweet Kid: If flashbacks to his and Shirayuki's past are anything to go by.
  • Weapon of Choice: A Beretta 92FS Inox modified to fire a three-round burst, which he conveniently names "Beretta Kinji Model", as well as a butterfly knife.
  • When He Smiles: Averted, since while he doesn't smile often, the times he does aren't treated as a big deal.

Aria H. Kanzaki Edit

Voiced by: Rie Kugimiya (Japanese) and Leah Clark (English)

A diminutive top student of Butei High's prestigious Assault Side.

  • A-Cup Angst
  • Aesop Amnesia: At the end of volume 1/episode 5, Aria tells Kinji that she'll stop calling Kinji her slave, yet she goes straight back to calling him that once he agrees to be the partner she wants.
  • The Ace: She's good at everything... except cooking.
  • Action Girl: The standout example for the series. She can wield two guns and two swords effortlessly, and is a skilled hand-to-hand combatant as well.
  • Animal Motifs: Cats. She is fond of "Leopon" stuffed cats, some key scenes involving her have random purrs, and in Episode 2 she even growls like a cat. In Episode 6, Shirayuki even calls her a "thieving cat"[1] for freeloading with Kinji.
  • Anti-Heroine: Like Kinji, she's a Type II. She's arrogant, egotistical and often resorts to violence over tiny things, but she's also very loyal to her fellow Butei and dedicated to clearing her mother's name. Not to mention the entire series started with her risking her life to save a guy she didn't even know.
  • Badass Adorable: A cute little girl who is an S-Rank Butei, which she has most definitely earned.
  • Belligerent Sexual Tension: With Kinji.
  • Berserk Button: Mention anything to do with relationships and she goes ballistic. She scared Riko half to death for thinking she and Kinji were dating.
  • Broken Ace: She's one of the best Butei around and skilled at everything except cooking, but she's also socially inept, had no friends before she met Kinji, and is borderline obsessed with clearing her mother's name.
  • But Not Too Foreign: She's half-Japanese, half-British.
  • Catch Phrase: I'll blow a hole through you!/I'll pump you full of holes.
  • Celibate Heroine: Aria claims relationships are nothing but a waste of time, and even looks down on people who think otherwise. She also says that she doesn't care about being in love and is never going to be. Yeah, right.
  • Clear Their Name: Aria's primary motivation for attending Butei High is to help clear her mother, Kanae, of charges of being the "Butei Killer", which automatically sent her to 862 years in prison. If successful, Aria could shave off centuries of prison time for her, and at the best-case scenario, even clear her altogether.
  • Clingy Jealous Girl
  • Cry Cute: A norm for Rie Kugimiya's roles.
  • Cute Little Fangs: With feline tendencies to boot.
  • Dual-Wielding: With both swords and guns, hence her name 'Aria the Quadra'.
  • The Dulcinea Effect: A rare example where it's the girl saving the guy- this is how she and Kinji first met. Unlike some examples, however, this definitely did not result in Love at First Sight.
  • Determinator: To the point that she hates people who aren't this.
  • The Dulcinea Effect: A rare example where it's the girl saving the guy- this is how she and Kinji first met. Unlike some examples, however, this does not result in Love at First Sight.
  • Embarrassing Nickname: "Defective Holmes", which she got due to the fact that she didn't inherit any of her ancestor's incredible deduction abilities.
  • Famous Ancestor: She's the fourth-generation descendant of Sherlock Holmes, explaining the "H" in her name.
  • Fiery Redhead: So much!
  • First Kiss: With Kinji, which also doubles as a "Shut Up" Kiss to her in order to pacify her after she was revived after being critically hit in the chest by Riko.
  • Forehead of Doom
  • Foreshadowing: Her ancestor's identity is hinted at when her mother tells her his legacy would be nothing with his 'partner'.
  • Girlish Pigtails
  • Guns Akimbo
  • Hair-Trigger Temper: It's incredibly easy to piss her off, even without the above Berserk Button. Her catchphrase alone should be enough of a hint.
  • Hypocrite: Downplayed. Aria often demands proof from people before she'll believe something that goes against her initial assumption, yet also expects people to take anything she says for granted. The reason this is downplayed is because, unlike other people, she has the Holmes Intuition, even if she can't explain it logically.
  • Hypocritical Humour: When Kinji comes into her room in the plane, she calls him out for barging in without an invitation, even though she did exactly that on the night of the day they first met. Kinji, of course, lampshades it.
  • Idiot Hair
  • Insufferable Genius/Know-Nothing Know-It-All: While she's mostly the former, she does have moments of the latter, such as when she flat-out refuses to believe that Kinji wasn't sexually assaulting her when they first met, no matter how many times he tries to explain himself.
  • Jerk with a Heart of Gold: She's bossy, short-tempered and often egotistical, but she cares a lot for her friends and loved ones, her mother and Kinji especially, and means well more often than not.

Aria: I know I can be a little overbearing at times, but it's for your own protection.

  • Lethal Chef: The only thing she's not good at.
  • Little Miss Badass: Despite her small size, she can easily kick your ass.
  • Luminescent Blush: Very prone to this.
  • Miss Conception: She thinks kissing instantly leads to pregnancy.
  • Older Than She Looks: Shown in the first episode, when Hysteria!Kinji mistakes her first for a middle-schooler and then an elementary school student. She's actually in her second year of high school. Her stunted growth is due to the 'Scarlet Bullet' embedded in her back.
  • The Ojou: Hinted to be one.
  • Omniglot: She knows seventeen languages.
  • Pretty Freeloader: She settles in Kinji's apartment without asking for his permission and gets to stay there without ever having to pay or help in the house chores.
  • Pride: One of her defining traits. Her reason for calling Kinji her 'slave'? It's because she's too proud to say 'partner'.
  • Rapunzel Hair: Even in her Girlish Pigtails, her hair still reaches way below her knees.
  • Rich in Dollars, Poor In Sense: Implied. Aria makes it clear early on that she hates people who use words like "tired" and "Impossible", claiming they're just excuses people use to hide the fact that they're just scared of their full potential. However, Kinji suspects her attitude towards those words are actually the result of being The Ojou and growing up in a society of "winners", which has resulted in a lack of understanding for those who are weak, poor or hopeless. 
  • Scars Are Forever: After a brush with death during the bus bomb incident, she has since kept a small X-shaped scar on her forehead (now hidden by her hair) as a reminder.
  • Shana Clone: And possibly the 5th Tsundere Wonder.
  • Spoiled Brat: She has shades of this. She definitely doesn't take 'no' for an answer, and often calls Kinji her 'slave' (though it's revealed early on that when she does, she means 'partner'). Being The Ojou likely has something to do with it.
  • The Three Faces of Eve: The Child (diminutive and temperamental, with bouts of innocence).
  • Tomboy and Girly Girl: Tomboy to Riko and Shirayuki's Girly Girls.
  • Tsundere: Type A- now with the voice to boot.
  • Trademark Favorite Food: Peach buns.
  • Unprovoked Pervert Payback: She accidentally takes a sip out of Kinji's soda and somehow that gives her the right to punch Kinji for being a pervert.
