Main Characters

     Hitomi Uzaki 

Hitomi Uzaki/Brute Ratel

Voiced by: Sora Amamiya

  • An Arm and a Leg:
    • Kido severs her right arm, yet she still wins against him. It is reattached some time later.
    • Nodoka chops off her right leg and left arm during the Deathtival's preliminaries. Yuuya brings her to an hospital afterwards, where she is put inside a regeneration capsule to get patched up.
  • Apologetic Attacker: The one and only time Hitomi is truly remorseful is when she believes she's killed Yuuya. While fervently denying she feels upset over it, she's openly crying as her escort drives her off.
  • Badass Adorable: She can be quite cute when she's not viciously fighting other Brutes.
  • Bad Ol' Badger: She's part honey badger, and she's also a Blood Knight who shows no mercy towards her enemies, feels no fear, and is near impossible to kill.
  • Berserk Button: She loves to fight, but she can be quite comically riled should you put a hand near her sweets.
  • Blood Knight: She loves fighting, even when the fight involves her getting punched by a lion.
  • Boobs of Steel: Has a huge rack, and is by far one of the deadlier female fighters.
  • But for Me, It Was Tuesday: In Episode 4, she doesn't recognize Leo and Bear despite having fought them before. Then again, she has never seen them in their human forms so it's probably justified.
  • Catchphrase: Hitomi always finds an excuse to brag that "The one with the sharpest fangs wins. That's what Killing Bites is." Ironically, the literal meaning of the phrase proves false several times through the story. It is implied she borrowed the phrase from her father Shidoh and in turn Yuuya borrows it from her, concluding the fangs in question are actually one's convictions.
  • Decoy Protagonist: In the first arc, she seemingly fulfills the role of the female protagonist of the entire manga, but when she slashes Yuuya at the end of the arc, she becomes The Heavy secondary antagonist to her boss Shidoh's Big Bad in the second arc, while Pure takes over as the female protagonist.
  • Determinator: Losing an arm, being stabbed and brutally beaten up, it doesn't matter. She doesn't give a shit.
  • The Dragon: For Shidoh, right down to following orders to dispose of Nomoto.
  • Dramatic Irony: The easiest kill she ever made was also the only one that didn't stick.
    • Her life was saved by Crow, who is probably the physically weakest Brute in existence and the man she hates more than anyone else.
  • The Dreaded: Hitomi becomes notorious after defeating Yuugo and performing well at the Destroyale.
  • Due to the Dead: She never spares targets note , even ones she sympathizes with, but before assassinating Nomoto she thanks him for staying with her and says it's Nothing Personal.
  • Evil Counterpart: To Pure, who is also an orphan but had love growing up. Hitomi didn't.
  • Fatal Flaw: Her egoism and overconfidence means she picks fights with any Brute unwilling to immediately recognize her superiority, must be repeatedly persuaded not to break The Masquerade, and does not Double Tap her victims. Not to mention she ultimately chooses to follow Shido's orders to kill Yuuya despite being reluctant about it, leading to Yuuya turning against her when he survives.
  • Foil: to Kido.
    • She the small Action Girl to Kido's bulky muscleman.
    • In regard to the Destroyale, Hitomi had to illegally acquire a "backer" to willingly participate. Kido, on other hand, got illegally acquired by a legal "backer" and forced into participation instead.
    • Just as Kido is only an "antagonist" due to his association with Youko Mikado, Hitomi is only a "protagonist" due to her association with Yuuya Nomoto.
    • Hitomi needs to transform first in order to stand her ground in a fight. Kido doesn't.
    • Their Brute forms are both Game-Breaker class in regard to offensive and defensive capabilities, only Hitomi favor overwhelming offensive skills in contrast to Kido's preference of unbreakable defense.
    • Personality-wise, Hitmoi is vocally abusive, rude, and loud towards anyone she meets. Kido on other hand remain as The Stoic and generally respectful towards people through his silence, even when they pushes his Berserk Button.
    • Hitomi fights only for herself and never others. Kido never fights for his own sake and only for the sake of something else (nature).
    • All of Hitomi's fights plays out as Single-Stroke Battle with lethal outcomes exceedingly rare as a result. Kido on other hand goes for One-Hit Kills with Deader Than Dead outcomes as common occurrence instead.
    • Hitomi's master is a Manipulative Bastard who treats Hitomi as a person and keeps her loyalty through a bond of genuine trust and love. Kido's master is a Manipulative Bitch who treats him as a tool at best and holds his loyalty-less leash through lies and pragmatism.
  • Green-Eyed Monster: After discovering that Yuuya is still alive after she thought she killed him, she becomes extremely jealous when she learns that he's training Pure.
  • Grievous Harm with a Body: She throws her own severed arm at Kido during their fight.
  • Half-Human Hybrid: She's an Origin Beast, a natural born Therianthrope.
  • Happiness in Slavery: Ratel is beholden to her "creator"- not humans in general- and he only ever asks her to fight, something her animal nature already compels her to do. She is both able and willing to bully 90% of the series' characters into serving her whims.
  • The Heavy: Her boss Shidoh is the Big Bad, but she is the primary antagonist needed to be taken down to get to Shidoh in the second arc.
  • Hidden Heart of Gold: You have to dig deep, deep, deep down, but Hitomi can grow quite attached to those around her and she can be capable of genuine kindness and warmth outside of battle. It won't stop her from killing some of them if Shidoh orders it, though. But she will, at least, feel bad about it.
  • Inferiority Superiority Complex: She grew up on the streets, with no family and nothing in her favor. So she internalized the idea that trusting anyone is fatal and can become borderline desperate in how far she's willing to go to prove her usefulness in order to ensure that her "master" doesn't abandon her as well.
  • Jack-of-All-Stats: Eruza mentions she's relatively fast, very resilient, and quite strong.
  • Just Following Orders: Right after Yuuya thanks Hitomi for teaching him to stand up for himself, she kills him because she's subservient to her father Shidoh. And Hitomi is all too willing to kill Yuuya as many times as needed after she learns of his survival, even though she rather likes the guy.
  • Koan: Her Borrowed Catch Phrase, to the point it becomes a Survival Mantra given the frequency it's used.
  • Love Is a Weakness: She never doubted herself until she assassinated Nomoto.
    "D-daddy, Nomoto is alive. What do I have to do?"
  • Made of Iron: Even by Therianthrope standards, she survives a ridiculous amount damage throughout the Destroyale. Most notably, getting Impaled with Extreme Prejudice by Kido still wasn't enough to put her down, while the same attack incapacitated both Ichinosuke and Taiga.
  • Mysterious Past: Shidoh reveals that no one, not even herself, knows where she came from or how she came to be.
  • Nerves of Steel: Justified since the honey badger is the world's most fearless animal. Hitomi only ever loses her cool when Kido severs her arm and when Tasuku manages to overwhelm her.
  • Not So Above It All: When she's roped into cosplaying, her innate honey badger sense of curiosity takes over and she begins really getting into it.
  • Offing the Annoyance: Played for Laughs. Annoyed at Oshie's terrible singing, she sucker punches her in the face to make her shut up.
  • Pint-Sized Powerhouse: The size of a regular school girl, with the viciousness of a honey badger.
  • Post-Victory Collapse: After defeating Kido, she gives one final animalistic scream and passes out.
  • Shameless Fanservice Girl: Not only she doesn't mind fighting only in her underwear, she doesn't mind making suggestive poses while cosplaying.
  • Single-Stroke Battle: Frequently wins fights in a single hit.
  • Slasher Smile: Usually she's quite reserved when in human form. When she's preparing for a fight or shifting to her Brute form, she can flash a gleeful, terrifying grin.
  • Sociopathic Hero: Rude, crude, arrogant, unbelievably selfish, violent, prone to throwing death-threats at everyone (sans her "legal guardian"), a massive bully, bossy, incredibly unpleasant as a person, cruel, impulsive, etc. In short, she's more of an animal than an actual human being most of the time. The only reason she can even be classified as a "protagonist" is due to her association with Yuuya who at least tries to iron in some redeeming qualities into her as a human being, something her "legal guardian" hopes she takes to heart.
  • Super Mode: When Hitomi is pushed to her limits, she reverts to her Origin form. She becomes furrier, dark-skinned and way more powerful and unhinged than usual.
  • Sweet Tooth: Loves honey. Especially with pancakes.
  • Thou Shalt Not Kill: The one humane quality that Yuuya managed to iron into her from their time together. Something she only made a rule after her "legal guardian" praised her for it, that is. Something that not only saved Porcupine and Cobra, but Yuuya as well.
  • Tsundere: Type A. She's tsun almost all of the time, only bringing out the dere in front of Shidoh, or when eating a large stack of pancakes.
  • Villain Protagonist: In the first arc, by the second arc she is a secondary antagonist.
  • Wild Child: She was this when she was young, acting more like an animal than a person.

     Yuuya Nomoto 

Yuuya Nomoto/Beast Crow

Voiced by: Wataru Hatano

  • Always Save the Girl: When Eruza is at risk of being raped and killed by Den, Yuuya gets Hitomi out of an advantageous position to help her out since they're friends. As a result, Hitomi has to face the entire Yatsubishi trio on her own after Den and Kaede are defeated.
  • Big Damn Heroes:
    • When Nomoto is reintroduced watching Pure and Tasuku's fight in the second arc, he's impressed by Pure and can't help but give instructions to help the beagle turn the tables on her favor. This ends up getting both girls disqualified.
    • After watching Pure and Tasuku getting walloped by the Nakanishi siblings at the Deathval, Yuuya decides to crash the tournament in his bird form and coach them closely. He arrives just in time to help the two against the now terrifyingly-huge Nodoka.
    • He saves Hitomi from getting stomped by Nodoka and, already feeling bad for Tasuku's death, hugs her to show how much he cares.
  • Big Good: After his brush with death and turned into a Brute, he become this of the second arc, having Took a Level in Badass and becoming a coach to Pure.
  • Borrowed Catchphrase: Finds meaning in Hitomi's "the sharpest fangs win" catchphrase. Then he says it once next to Tasuku and she starts saying it too. It's infectious.
  • Broken Pedestal: Yuuya admired Hitomi's bold personality, but came to painfully realize how much of a pawn to her father she really is. When they meet later on, he talks down to Hitomi with varying levels of disdain and seems set on humbling her one way or another.
  • Came Back Strong: The cliffhanger ending on volume 10 reveals Yuuya became a Brute after he nearly died. Later on we learn he's a crow-man. While seemingly not much of a fighter, he can fly circles around everyone else. It's to be seen if it's was artificially or if he's an Origin like Hitomi and manifested due to her homicide attempt.
  • Character Development: While Yuuya starts out as a weakling, he does his best to survive under the grasp of megacorps whose beastmen could kill him anytime and get away with it. He figures out their way of thinking and makes his own decisions through the Destroyale even when met with mockery. In the end Yuuya decides to learn to be as brave as Hitomi is and getting slashed to near-death by her is just the motivator he needed for a stark personality change.
  • Clever Crows: Becomes a cunning crow-man after the time skip.
  • Contrived Coincidence: Yes, it's traditional for the genre, but...what are the chances two potential werebeasts could end up in the same van?
  • Creepy Shadowed Undereyes: Apparently Yuuya has been severely sleep-deprived since he's had to live in hiding for 2 years and come up with a plan to take down Shidoh's corporation. It also adds to giving him the appearance of a crow's eyes..
  • Dating Catwoman: Although mad at Hitomi for trying to kill him and having some sort of plan against her father's organization, Yuuya still cherishes her.
  • Expository Hairstyle Change: After being almost killed by Hitomi he starts wearing his hair down.
  • Extreme Doormat: The guy gets pushed around by others way too easily, that is even the reason why he met Hitomi in the first place.
  • Faking the Dead: After Hitomi nearly kills Yuuya, he's forced to go into hiding and forge a new identity as a trainer for hybrids. Only after making some sort of plan against the Zaibatsu does he make his survival known.
  • Foreshadowing: When Yuuya first transforms, what looks like either feathers or scales start growing out of his forehead, narrowing out the possibilities for the reader to guess. In hindsight, Yuuya turning into a bird is also hinted by him learning to use whistling to command others.
  • From Nobody to Nightmare: He was supposed to be an easily disposable patsy, but Seira understands that disposed-of patsies have their own usefulness, if they're angry at your enemies...
  • He Knows Too Much: On the receiving end. After the first fight, Yuuya promises he won't tell anyone about the Killing Bites... unfortunately, Ratel and her master are not convinced of that. On the plus side, they don't kill him — just keep him under very close watch. And use him as a means to legally get Hitomi into the tournament as her "backer". Eventually, however, Shidoh does orders Hitomi to kill Yuuya. He somehow survives this, wises up and begins a revenge plot against the Zaibatsu.
  • Mistaken for Badass: By the Ishida faction. Due to small misunderstandings and coincidences, he earns Brute Hippo's respect for being the one capable of "holding Ratel's leash" and "Stand up to Youko Mikado"(Manga only) without any repercussions. During the Destroyale, the amount of respect he earns from the players of Ishida only multiplies as he proves himself as a player on the board for the duration of the tournament, but this time he has earned it.
  • Loophole Abuse: He convinces Hitomi to go with him by pointing out that while she's not allowed to participate in the tournament...her mission is to keep tabs on him. And if he goes there, doesn't that mean she has no choice but to follow him?
  • Nice Guy: A genuinely pleasant individual who tries to look out for his team during the Killing Bites tournament, even as he's scorned for it by the more ruthless players.
  • Non-Action Guy: Downplayed after he turns into a bird man. Yuuya serves a surporting role as a coach to Pure and Tasuku and won't fight anyone directly, but he'll come flying to the front lines when needed to give them orders and to carry Pure and toss her at enemies like a missile.
  • Only Sane Man: Being a normal college student caught up into the dark side of the Killing Bites, he's utterly flabbergasted over the ruthlessness and callous nonchalance displayed by the Zaibatsu towards their Brutes and each other.
  • Rich Idiot with No Day Job: Masquerades as one after the first arc. He doesn't tell his Brutes the real reason he's a sponsor, so Tasuku assumed he was just doing it for fun. But he seemed harmless and paid well, so she joined up with him anyway.
  • Ridiculously Average Guy: A perfectly average and unlucky college student who got dragged into the hidden world of Killing Bites completely by chance. The overall impression of him differs from person to person though.
  • Save the Villain: Rushes Hitomi to a hospital after she's horribly injured and dismembered by Nodoka.
  • Speaks Fluent Animal: Implied Trope. Crows possess the ability to communicate with other species, an ability often used to ally themselves with canine packs. The narration mentions this ability in the same chapter that Nomoto's unusual talent for leading other hybrids is noted by several people.
  • Stand Your Ground: During the fight between Hitomi and Taiga, he's given the option to order Hitomi to pull out when it became his turn to roll the dice. Instead, he decides to pass his turn and let Hitomi continue fighting.
  • Stealth Pun: The kanji for "crow", 鴉, is made of 牙, for "fang" and 鳥, for "bird". That's what Killing Bites is.
  • Tengu: Like the mythological Youkai, he's a mysterious individual that takes a young hero under his wing and trains them as a fighter. He's also a crow, like the legendary Karasu Tengu.
  • The Power of Hate: Although fairly intelligent, he never felt motivated to do anything with his life or take any risks until the day Hitomi murdered him. After that, he concluded that if he was going to die no matter how he acted, he might as well go down fighting.
  • Too Awesome to Use: His share of the prize money from being part of the winning faction in the aftermath of the Destroyale,(Three suitcases packed with hundreds of millions yen in hard cold cash), as not only do they serve as proof that his whole involvement in the Killing Bites happened, the insane sum alone leaves him too terrified to use a single yen of it, resulting in the three suitcases being left alone under a cloth in the corner of his room. Until his supposed demise at Hitomi's hands of course...
  • Took a Level in Badass: Being sliced open, left for dead and recovering have turned Yuuya into a far less naive, far more intelligent and dangerous figure who's even now a Brute himself.
  • Winged Humanoid: His arms turn into fairly large wings when he transforms.
  • With Friends Like These...: Most of his friends before he met Hitomi turned out to be a bunch of gang-rapists who tricked him into assisting them with their crime. Trying to force oneself upon a Brute Honeybadger turned out to be a really bad idea for them.
  • You Have Outlived Your Usefulness: Shidoh attempts to have Hitomi dispose of him once he's no longer of value, and he knows too much to be allowed to go free.

The Four Zaibatsu


     In general 
  • Enemy Mine: Ishida and Yatsubishi conspired together against Mitsukado with Shidoh's help.
  • A Lighter Shade of Black: While they're just as ruthless as the other Zaibatsu, they at least have a sense of honor and fair play.
  • Obfuscating Stupidity: Toh Son looked like a spineless Henpecked Husband, but once Ishida wins the Destroyal he drops all pretenses and tells Youzan to shove it.
  • The Starscream: They conspire alongside Yatsubishi and Shidoh to get rid of Youzan and get the profits of the Therianthropes
  • Token Good Teammate: When compared to the other Brutes, Okajima and Ui are far nicer and moral. The same goes for their faction.
  • Two Girls and a Guy: Their team for the Destroyale is composed of Hitomi, Ui, and Ichinosuke.

     Ui Inaba 

Ui Inaba/Brute Rabbit

Voiced by: Sumire Uesaka

  • Action Survivor: Survived enough battles to earn an unfortunate reputation as a "lost call" among the Beasts. Something she doesn't take much pride in in hindsight.
  • Ascended Extra: While far from an extra in the manga, it’s undeniable she has more presence in the anime. In the manga she was properly introduced halfway through the Destroyale with a short flashback later explaining how she was recruited by the Ishida faction. The anime shows the contents of the flashback in real time and greatly expands it, and then proceeds to have Ui appear in much more scenes than in the manga in the following episodes.
  • All Women Are Lustful: She hides it well, but the moment she came in contact with a weakened version of Civet's "Civet Wrap", she went into heat immediately. There's a reason her brute-surgery turned her into "The Rabbit" all things considered.
  • Bring My Brown Pants: She understandably wets herself when she sees Kido punching his own teammate in half.
  • Dark Horse Victory: Literally no one, not even herself, saw her accidentally kicking Eruza in the face and knocking her out, emerging victorious.
  • Faux Action Girl: Following the events of the Destroyale, Ui becomes the poster girl for Killing Bites and the manager of an underground fighting ring. She commands respect as the one who won that tournament by supposedly defeating Taiga and Hitomi despite when in reality, she only won one single fight during the whole tournament (against Brute Civet). Her meek personality prevents her from correcting any of the rumors around her and she puts up pretenses of them being true just so the people won't get hurt from the truth.
  • Heart Is an Awesome Power: Even if she thinks otherwise, having a pair of strong legs and good ears does a good job at keeping her alive when confronted with predatory Beasts in actual combat. Although she's supposed to play a support role in the Destroyale, digging tunnels to spy on the other brutes and relay the information back to her teammates, she ends up winning the competition by surviving to the end and defeating two Brutes out of sheer rabbit foot luck.
  • Killer Rabbit: Played With. Ui is anything but a killer. She's relatively weak, reacts to 'Fight or flight' with flight every time. But, she wins the Destroyal, taking out Civet and Cheetah.
  • Lovable Coward: An extremely nice girl and general sweetheart who will freeze up and try to flee at the first hint of danger and has to be practically coerced into joining Killing Bites. Hilariously, her cowardice actually directly leads to her overall victory.
  • Sailor Fuku: Her school uniform.
  • Tunnel King: The one thing about her Beast powers that she truly enjoys doing,(like with actual rabbits), is digging and digging to the point everything else in her mind gets pushed aside in favor for her fun.
  • You Gotta Have Blue Hair: Has pink hair, which fits her rabbit image.

     Ichinosuke Okajima 

Ichinosuke Okajima/Brute Hippopotamus

Voiced by: Toru Okawa

  • Acrofatic: Like a real hippo, he can move very fast in small bursts despite his large size.
  • Badass Teacher: In the second arc, he's become a teacher but can still intimidate others with his sheer size and presence.
  • Big Damn Heroes: Twice. The first when butting in between Tiger and Crocodile, saving them both from each other and a second time to save Tiger from Kido, despite his own injuries from the former wearing him down.
  • Dynamic Entry: He actually has entered the scene tackling an opponent three times, and they never see him coming.
  • Face Death with Dignity: When left alone with Tiger, he knew how dead he was yet decided to not just stand and take it like a lamb. Fortunately for him, Tiger got called away before they could exchange a final blow.
  • Gentle Giant: Unlike an actual hippo, he's a rather pleasant guy.
  • Honor Before Reason: Even if it come back to bite him later on in a fight, he will always fight to save the lives of others foremost. May they be the ones of his opponents, strangers, friends and his own.
  • I Owe You My Life: His undying loyalty to the Ishida faction stem from the benevolence of his benefactor Seira Son, who not only employed him, but helped his family financially out of a pinch as well.
  • Impaled with Extreme Prejudice: He was tough enough to survive a blow from Pangolin's tail, but it put him out of the Destroyal for good.
  • Kevlard: Through semi-transforming his skin, he can take potentially lethal hits such as the ones from Tiger's claws without dying first.
  • Oh, Crap!: Has this reaction continuously because he knows most of the opponents he encounters outclass him in one way or the other.
  • Stout Strength: Unsurprising for a hippopotamus, he's big and resilient.

     Seira Son 

Seira Son

Voiced by: Yoshino Nanjo

  • Everyone Has Standards: While a ruthless player of the Killing Bites, she believes Brutes shouldn't throw away their lives in the pursuit of victory. This makes her far less callous than the other players.
  • Know When To Fold Them: After seeing Kido kill Crocodile in a single punch, she wisely orders Okajima to retreat.
  • Nerves of Steel: While everyone else gets sick at Kido pummeling crocodile's corpse to a pulp, she keeps her cool and orders Okajima to get out of there.
  • Secret Keeper: During the Time Skip, she is one of the few people to know about Yuuya's survival. Exactly what kind of arrangement they have isn't known, but she's willing to vouch for him by claiming he's a relative.


     In general 
  • Enemy Mine: They conspire with Ishida and Shidoh to get rid of Youzan.
  • The Rival: They're Mitsukado's main rival in terms of power and influence.
  • The Starscream: They work with Shidoh and the Ishida faction to make a coup detat to remove Mitsukado from power.
  • Two Girls and a Guy: Their team for the Destroyale is formed by Taiga, Eruza and Kaori.

     Eruza Nakanishi 

Eruza Nakanishi/Brute Cheetah

Voiced by: Maaya Uchida

  • Big Brother Worship: She adores her older brother to such a high degree that Civet honestly mistook it for something ''completely'' different.
  • Bond Villain Stupidity: Eruza finishes off Kido with a sneak attack and boasts that cheetahs don't fool around. But then she spots Ui waking up and decides to just bully her for a while. This gets her knocked out from a sudden kick to the face.
  • Designated Girl Fight: Her first major opponent in the Destroyale is Kaede the gecko. In fact, most of her major fights are against women.
  • Fragile Speedster: Like a cheetah, she hits pretty fast, but can't take many hits.
  • Friendly Enemy: Despite being on opposing sides, she's genuinely friendly with Hitomi when they aren't fighting.
  • Going Commando: She clearly doesn't wear anything beneath her sarong while on the Destroyale.
  • Interplay of Sex and Violence: When Hitomi bites off a piece of her transformed hand during their fight, Eruza declares that she may fall for her. She later insults Kaede by declaring her attacks aren’t strong enough to turn her on.
  • Letting Her Hair Down: By the next part of the story, she has stopped wearing pigtails and now it falls to the middle of her back.
  • Panthera Awesome: She's a cheetah.
  • Panty Thief: The first thing she does in the series is steal Hitomi's panties and run away with them.
  • Psycho Lesbian: Downplayed Trope. She is introduced stealing Hitomi’s panties, claims to have almost fallen in love with her when she managed to draw blood during their fight, and overall seems to subscribe to Interplay of Sex and Violence. But despite all this, she is still one of the least violent and sadistic Brute in the series, and outside of battles she behaves like a normal girl.
  • Reused Character Design: Looks like Gokiburi from the author's previous work Arachnid and is introduced creeping on Hitomi with the same school uniform roach girl wore in that series to drive home the point. Their personalities do differ in that Eruza is actually more well adjusted than Goki.
  • Spell My Name with an "S": Called "Elsa" in some promotional materials.
  • Took a Level in Badass: During the Deathval, Eruza appears more ruthless than before and is able to perform her brother's Tiger Cannon attack.

     Taiga Nakanishi 

Taiga Nakanishi/Brute Tiger

Voiced by: Yuichi Nakamura

  • An Arm and a Leg: Loses his right arm to Kido, although by the time skip it's been reattached.
  • Bishōnen Line: He's the first male Brute that retains a human face (and apperance) in battle form.
  • Blood Knight: Taiga only really takes enjoyment of fighting in a Killing Bites if he can take on Leo, but the guy keeps finding excuses to abstain from the tournament. As such, Taiga goes around the Deathval curb-stomping everyone with contempt, feeling like all the new hybrids don't deserve to be there.
  • Cats Are Superior: He sees any non-feline Brute as inferior to him and Leo.
  • Expository Hairstyle Change: After the Time Skip, he trimmed his long hair short.
  • Flash Step: With his Tiger Cannon, Taiga is able to instantly leap out of the target's view and then backstab them. If you know the author's previous works, the scene where Hitomi nearly counters him should seem familiar.
  • Impaled with Extreme Prejudice: Kido stabs him in the stomach with his tail, leaving him out of the competition, He recovers eventually.
  • Lightning Bruiser: He's fast and hits hard.
  • Let's Get Dangerous!: When he gets truly serious, his sideburns get covered in fur and his claws get even sharper.
  • Panthera Awesome: He's a tiger.
  • Punny Name: "Taiga" sounds like "tiger".
  • The Rival: Sees Leo as his rival because of their opposite species, and is rather disappointed he's unable to participate in the Destroyale.
  • Smug Super: While overconfident, once he gets serious there's a very strong chance you'll end up dead.
  • Taking You with Me: He actually considers letting his necklace explode to kill Crocodile as well. Luckily Ichinosuke saves them both.
  • Underestimating Badassery: He believed Gorilla and Crocodile were easily dealt with, only for Crocodile to nearly kill him when he lowers his guard. And Gorilla appears fine afterwards.
  • Villainous Rescue: Saves Hitomi from Kido's killing blow, though he only did it because he's pissed that the latter is stealing his prey.
  • The Worf Effect: Taiga is genuinely strong but suffers from this trope against the story's main antagonists. He's said to have been defeated by Yuugo, and is constantly cheated out of a rematch. In the Destroyale Taiga is defeated by Kido, and after being disqualified from the Deathtival because of Kaede's defeat he ends up brutalized by a little girl, Koyomi, and is sent to a hospital in a coma.
  • Worthy Opponent:
    • He starts seeing Hitomi as this after she survives his "Tiger Cannon" twice, something only his rival Leo had been able to do until this point.
    • During the Deathtival he holds most of the contestants in contempt, but enjoys fighting Pure and Ena because they manage to boldly struggle against him despite the difference in their level.

     Ryoko Araka 

Ryoko Araka/Brute Porcupine

Voiced by: Natsuko Hara

  • Bit Character: A Starter Villain that is quickly defeated and unlike Leo, she doesn’t really come back later. She does sign in for the Deathtival, but gets beaten up offscreen by Hitomi.
  • Flechette Storm: Her super-move, as it involves throwing a bombardment of her quills at whoever is in front of her.
  • Sadist: She apparently once stabbed a man with her quills for 10 days until he died.
  • Shameless Fanservice Girl: Doesn't mind flashing her assets to Yuuya to get him to lower his guard.
  • Spikes of Villainy: She's a porcupine, and a sadistic bitch.
  • Starter Villain: Like Leo before her, she's the second opponent Hitomi battles in the series.
  • This Cannot Be!: She can only scream this way when Hitomi proves herself to tough to pierce.

     Kaori Rikujou 

Kaori Rikujou/Brute Civet

Voiced by: Yuu Asakawa

  • Did Not See That Coming: She didn't expected Hitomi to snap from her trance before Eruza did, leaving her to face the angered Ratel alone.
    • She also didn't expected Ui would be smart enough to drive her to a pitfall, leaving her out of the competition.
  • Disney Villain Death: Ui defeats her by luring her to a pitfall.
  • Evil Cannot Comprehend Good: Utterly flabbergasted over Hitomi's decision to spare and save Cobra before engaging Tiger in a fight. Hitomi's nonchalant answer only confuses her further.
  • Feel No Pain: A side-effect of her "Civet Wrap", which numbs anything even resembling pain in those affected by it, something that managed to get Cobra back in the game, post-defeat, despite being cut in half already.
  • Kicking Ass in All Her Finery: Her outfit for the Destroyale seems more fitting for the party she attended beforehand than the battlefield. Her dress does have a practical use, as it allows her to spread her aphrodisiac easier in the air while remaining decent about it.
  • Living Aphrodisiac: Her ability, which essentially allow her to turn any battlefield she arrives on into an orgy instead.
  • Nice Hat: And it even obscures her face during her introduction.
  • Offhand Backhand: She does this to Cobra when the latter tries to sneak up on her. Manga-only.
  • Oh, Crap!: When she notices a pissed off Hitomi is right behind her.
  • Power Perversion Potential: She uses the natural aphrodisiac of a civet to make her opponents so aroused they won’t be able to fight back and become easy prey. Plus, she can provide some nice shows for her bosses.
  • Seldom-Seen Species: When compared to the other participating Brutes, civets aren't that well known in popular media.

     Yashin Iwasaki 

Yashin Iwasaki

  • Big Bad: After the Mitsukado faction is taken out, Yashin takes Youzan's place as the gleefully evil guy who's pushing Shidoh around for some kind of so far unstated evil plan.
  • Dissonant Serenity: He always has a serene, almost happy expression, which makes him look disturbing. Even when pretending to worry for an injured Taiga, he comes as creepily calm.


     Youko Mitsukado 
Voiced by: Megumi Han
  • Alas, Poor Villain: After he murders her grandfather, Leo finalizes his takeover by forcing himself on her. The narration explicitly compares it to a male lion taking over a pride, killing the leader and then mating with the females. After the Time Skip, she's being kept as Leo's Sex Slave while he controls her family's company.
  • Animal Motifs: Youko has been compared to lionesses by the narrator since Leo made her his "mistress".
  • Berserk Button: Anything that could, in her eyes, desecrate the "noble" sport that's Killing Bites. Anything. Shidoh and the ones connected to him in particular.
  • Blue and Orange Morality: Normally being disgusted with the way Yatsubishi was using Brute Civet would qualify as an Even Evil Has Standards moment, but seeing how she still thinks of the death match that is the Killing Bites as "noble", it seems it's not a matter of her having standards as much as her having her own unique moral compass.
  • Break the Haughty: After spending the entire competition being smug and condescending towards Yuuya and the other players, after Hitomi defeats her ace Kido, her grandfather, the one person she tried to "save" from Shidoh, gets killed by Leo. And now she's Leo's slave.
  • Cheaters Never Prosper: Being the only player that resorted to cheating (through her illegal acquirement of Brute Pangolin, a Brute that got banned from the Killing Bites tournament after his first and only match before the Destroyal,) she not only gets called out on it by the Ishida Faction, she, in the end, not only loses the "Invincible Pangolin" during the game but her grandfather and all of her status, power, and influence as a Mitsukado as well. To put the cherry on the top, she ends up as the plaything of Brute Leo, who wastes no time in gleefully pushing her "against the wall" beneath him after the coup.
  • Didn't See That Coming: She didn't expect Hitomi to transform further and become powerful enough to match Kido. Seira Son even lampshades this.
  • The Dog Bites Back: Youko eventually gets fed up with how Leo treats her and goes to Seira's bank to ask for assistance in participating on Killing Bites again. The narrator chimes in to comment that lionesses have no sense of loyalty to lions and will kick them out if they prove unworthy.
  • Dramatically Missing the Point: The moment her victory is within grasps, she goes rabid on everyone, gloating to kingdom come about Mitsukado's "supreme" superiority over the others and their "second-rate Brutes", despite herself being the only one who essentially had to retort to cheating, (By overstepping the authority which prohibited Kido from ever entering Killing Bites while also recruiting him through deception as she feed him false information regarding Hitomi/Ratel just to get his cooperation.) In comparison, even the Sumitomo-faction and its Reptilian Brutes played the Destroyale more honorably than she did.
  • Hime Cut: Which fits her demeanor and position.
  • Horrible Judge of Character: Her impressions of others are only based according to ''her'' standards, which inevitably results in her being wrong about practically everyone. It says a lot that the only person she manage to pin down just right, is Kido.
  • Irony: Her utter spite and belittlement of Yuuya due to him being utterly submissive and at the mercy to the whims of Brute Ratel comes back to bite her hard when she ends up in a even worse position under Brute Leo's paw and whims after the latter's coup against her grandfather.
  • Laughing Mad: Does this after boasting about how great her zaibatsu is and mocking her opponents for being 'second-rate'.
  • Nice Hat: Introduced wearing one.
  • The Proud Elite: Her pride borderline on hubris regarding her heritage and considering how Yuuya is the first person who ever managed to stand his ground against her will, quite spoiled. Even her main reason for participation in the Killing Bites revolves around "restoring" the pride of the tournament and her Grandfather which she blames Shidoh for defiling with his existence and experiments.
  • Purple Eyes: Which also make her stand out.
  • Screw the Rules, I'm Doing What's Right!: In accordance to her own standards, she sees nothing wrong in going out of her way to acquire a Brute that proved so brutal and dangerous that it was banned from the Killing Bites tournament by its benefactors. As long it could bring her victory, she couldn't care less about anything else.
  • Rape as Drama: After he murders her grandfather, Leo finalizes his takeover by forcing himself on her. The narration explicitly compares it to a male lion taking over a pride, killing the leader and then mating with the females.
  • Sex Slave: Leo spares her life during the coup, making her into his plaything.
  • Shared Family Quirks: While she may have not noticed it, she sticks out her tongue like a maniac in the same way as her grandfather when she sees Kido lay waste to his opponents.
  • Slave Collar: She wears a surprisingly tasteful one as Leo's "girlfriend".
  • Tempting Fate: After boasting that she'll never lose to her 'second-rate' opponents, she ends up getting eliminated from the tournament when Kido gets defeated by the very same 'second-rate Brutes' she's been mocking.
  • This Cannot Be!: Screams like mad when she sees Hitomi bringing down her trump card Kido, and although she briefly recovers, when Eruza finishes off the injured Pangolin, sealing her defeat, she completely loses it.
  • This Is Unforgivable!: Being already ticked off with Yuuya's participation in the Killing Bites, she goes absolutely livid when witnessing Yatsubishi's move with their piece "Brute Civet" and the degree of desecration to the Killing Bites tournament it made, swearing internally to kill everyone in the room once the tournament is over.
  • Tranquil Fury: Keeps a calm tone of voice even when it's obvious she's livid at the desecration of the Killing Bites.
  • Unknown Rival: Wants to crush Yuuya and Hitomi for being newbies at the Killing Bites. Yuuya doesn't notice how much she dislikes him and Hitomi hasn't even interacted with her yet (not that she would care).
  • Unwitting Pawn: She was completely unaware of everything that went behind the scenes with the other Zaibatsu, and now she's nothing more than Leo's slave.

     Youzan Mitsukado 
Voiced by: Hidekatsu Shibata

  • 0% Approval Rating: None of the other Zaibatsu like him, nor his faction as such they have no problem working with Shidoh to kill him.
  • Bodyguard Betrayal: He's killed by his own bodyguard Leo.
  • Didn't See That Coming: Turns out his pride blinded him completely to Leo's betrayal.
  • Dirty Old Man: He's basically drooling at the fights involving Hitomi.
  • It Amused Me: Why does he lets Shidoh continue with his experiments? It will make the Killing Bites more entertaining for him.

     Yuugo Tani 

Yuugo Tani/Brute Leo

Voiced by: Yuki Ono

  • Dented Iron: His injury after the fight with Ratel becomes the sole reason he gets pulled out from the Destroyal, much to Tiger's frustration and disappointment.
  • The Dog Bites Back: He betrays Youko and explains that he's doing it because she treated Brutes like playthings. So he makes her his Sex Slave in exchange for letting her live.
  • Dragon Ascendant: After murdering Youzan, he seizes control of what is left of the Mitsukado and enslaves Youko as his Sex Slave.
  • Faux Affably Evil: Yuugo appears rather pleasant outside of combat, but still a ruthless enforcer of the Mitsukado. However, under that? Yuugo is ruthless, devoid of conscience or loyalty save to himself and murders Chancellor Youzan before raping his granddaughter Youko.
  • First-Name Basis: He's the only one who calls Tiger by his first name.
  • I Have You Now, My Pretty: Once Youzan has been killed, he proceeds to force himself on Youko, just like how lions proceed to mate once they have gotten rid of their competition..
  • Kick the Son of a Bitch: Killing Chairman Youzan is done for brutal, self-serving reasons, but given Youzan's corruption and sadism, one can't feel too bad for him.
  • King of Beasts: He's a lion, and has all the pride and ferocity of one. He also reminds Youko he only works for himself, right after he killed Youzan.
  • Mighty Roar: His roar is so powerful most animals are paralyzed in fear, except Hitomi of course.
  • Pet the Dog: Despite treating Youko like a sex slave and parading her like a trophy, Yuugo is glad that she fled from him and turned over a new leaf under Seira Son's care. Later Yuugo saves her from rapist kidnappers, ironically enough, and leaves her be after hearing she plans to participate in the next Killing Bites as a team manager against him.
  • Rape Is a Special Kind of Evil: Taiga describes his rival as a noble Brute, showing mercy to the weak. However, any doubts about his ruthless and cruel nature are put to sleep when he rapes Youko and forces her to become his slave.
  • The Rival: Taiga sees him as one.
  • The Starscream: He kills Youzan in the same way lions kill other males to obtain females, in this case Youko.
  • Starter Villain: He's the very first Brute Hitomi faces in the story, and is quickly defeated.
  • The Worf Effect: While he's a genuinely strong Brute, he's quickly defeated by Hitomi to show her strength.
  • Willfully Weak: This is why Taiga does not acknowledge Hitomi's victory over Leo because he knows that Leo only goes all out against those he considers his equal. Hence, losing to Hitomi was deliberate on his part.

     Gérôme Hongou 

Gérôme Hongou/Brute Bear

Voiced by: Taketora

  • Bears Are Bad News: He's a bear man, and utterly ruthless in battle.
  • Big Guy Fatality Syndrome: The biggest member of Mitsukado's team, and the first to be defeated.
  • Flat Character: In the anime. Due to his backstory being Adapted Out, he comes across as just another Brute to suffer The Worf Effect by Hitomi’s hands, with no personality or motivation.
  • Sole Survivor: He's probably the only member of his three-man team to return alive from the Destroyale after Kido kills Shouta and Kido is killed by Hitomi and Eruza.
  • These Hands Have Killed: Subverted Trope. When he retired after killing a man in self-defense, everyone thought this trope was in effect. In reality, he retired because he wanted to kill more.

     Shouta Yabe 

Shouta Yabe/Brute Gorilla

Voiced by: Yuusuke Kobayashi

  • Affably Evil: Remains calm and polite during most of his fights, yet is as merciless as any other Brute.
  • Berserk Button: Those weaker than him (as they remind him of what he was like before the Beast Surgery) and those stronger than him (which reminds him of the bullies that made his school years a living hell). Whenever these buttons are pushed, he goes apeshit and straight for the smashing, consequences be damned. Which ends up biting him in the end as a casualty of "friendly fire".
  • The Berserker: Once he starts fighting, everything else gets pushed aside from his head until his opponent can't fight back anymore, snapping him back to his senses. Which is also what does him in during the Destroyale, ''twice in a row'', against Kido.
  • Death by Irony: He goes through the trouble of warning Crocodile about not messing with Kido, only to be killed by the same man after doing exactly what he warned Crocodile about less than an hour beforehand.
  • Half the Man He Used to Be: How Kido kills him.
  • He Who Fights Monsters: Initially went through the Brute surgery in order to get back at his bullies but in the end, became one himself towards those who're weaker than him, as his "match" with Rabbit shows.
  • Killer Gorilla: He is a gorilla, and has no intention of being merciful to his opponents in the Destroyale.
  • Oh, Crap!: His reaction when he realizes that, while chasing after Rabbit, he also destroyed some Kido's presence.
  • Too Dumb to Live: Not only does he know more than anyone that Kido will not show mercy to anyone who harms nature, but he also saw firsthand what happened to Crocodile when Kido catches him destroying trees. Despite this, he ends up doing the exact same thing while chasing after Rabbit. No points for guessing what happens next.
  • Top-Heavy Guy: His battle form makes his arms look gigantic in comparison to the rest of his body.
  • Villainous Breakdown: After remaining calm and collected during most fights, he loses his composure when he fails to kill Ui, and loses it completely when he finds himself unable to harm Kido.
  • What an Idiot!: Had he just followed his player's orders and aborted his pursuit of Rabbit on the spot, he wouldn't have triggered Kido and ended up killed by him.

     Takeshi Kido 

Takeshi Kido/Brute Pangolin

Voiced by: Ryoukan Koyanagi

  • Abusive Parents: His father was a nasty piece of work, and when he crushed a potted plant he was taking care of, he snapped.
  • Achilles' Heel: The only parts of him that are worth attacking are his eyes, the inside of his mouth and his throat.
  • Ambiguously Evil: Kido is more of a victim than a villain, as he not only was tricked into participate in the Destoryale, but is also the most morally neutral participant of the event with his single-minded Nature Lover creed and no desires of personal benefits for himself during it.
  • Arc Villain: The ultimate threat in the first arc's Destroyale. Kido slaughters his first few victims with zero effort and it takes the efforts of various characters to wear him down until he's finally defeated.
  • Badass Normal: He's already stronger than a crocodile in his base human form.
  • Bald of Awesome: Crossing with Bald of Evil, but he's completely bald, and is easily the most dangerous Brute in the competition.
  • Berserk Button: Harm nature in his presence, and you'll find yourself dead within seconds.
  • Berserker Tears: When being forced to relive his past traumas during his rage-induced mental breakdown, the tears won't stop flowing as he rages on.
  • Be the Ball: Can turn into a practically impenetrable ball, like an actual pangolin, and roll over his enemies.
  • The Brute: The guy is far more vicious than Shouta and Hongou, and appears even less intelligent.
  • Death by Irony: Gets a punch through the head not unlike the one he killed Crocodile with a while earlier.
  • Disproportionate Retribution: You damaged some trees, then you're as dead as a doornail.
  • Even Bad Men Love Their Mamas: Kido is traumatized over how his mother left home with another man to get away from her abusive husband. He's come to be overprotective of plants because she once told him to care for them as he would care for her.
  • Eye Scream: Tiger manages to slash his right eye with his claws, but it barely inconveniences him.
  • Foil: to Hitomi.
    • He the bulky muscleman to Hitomi's small Action Girl.
    • In regard to the Destroyale, Kido got illegally acquired by a legal "backer" and forced into participation, Hitomi on other hand, had to illegally acquire a "backer" first and is willingly participating in the tournament.
    • In terms of moral scale, just as Hitomi is only a "protagonist" due to her association with Yuuya Nomoto, Kido is only an "antagonist" due to his association with Youko Mikado.
    • Kido doesn't need to transform in order to hold his own in a fight. Hitomi does.
    • Their Brute forms are Game-Breaker class in regard to offensive and defensive capabilities but Kido's favors defense in opposite to Hitomi who favor offensive skills over her sturdy hide.
    • Kido is The Stoic and generally respectful towards people in his presence through his silence, even when they pushes his Berserk Button, Hitmoi on other hand, is vocally abusive and prone to overall rudeness and verbal abuse towards anyone she meets but doesn't have any Berserk Button to be pressed when she fights.
    • Kido fights only for others (In this case, "Nature") and never for himself. Hitomi fights only for herself (and on request for her master) instead.
    • Kido goes for One-Hit Kill with Deader Than Dead outcomes as common occurrence, Hitomi's fights plays out as Single-Stroke Battle with lethal outcomes exceedingly rare as a result.
    • Kido's master is a Manipulative Bitch who treats him as a tool at best and holds his leash through lies and pragimatism. Hitomi's master is a Manipulative Bastard who treats Hitomi as a person through a bond of genuine trust and love instead.
  • Freudian Excuse: His undying protectiveness of nature stems from a promise he made with his mother as a child before she disappeared, making the plants into a Parental Substitute for her instead.
  • The Fundamentalist: To him, nature is sacred (he's not wrong about that) and if anyone actively disrespect that idea, he'll make those people into fertilizer for the next generation of trees to grow from. He ignores anyone who does respect them though.
  • Go Out with a Smile: Just as Hitomi is about to pierce his skull, he, in the midst of his trauma-induced delirium, confuses her with his long gone mother and smiles for the first time.
  • Irony: Kido accepted the mission of Hitomi's/Ratel's elimination on the provided basis that she's a "crime against nature" and needed to be returned to it. Being a Origin Beast and by virtue the only natural born hybrid in existence, she's the one Brute that he shouldn't be going after to begin with, in accordance to his creed.
  • The Juggernaut: Due to his Beast affliction, once Kido is deployed in battle, nothing will stop him to carry out "nature's will". Not even having his brain splattered all over his neck and back by Hitomi is enough to put him down.
  • Last-Name Basis: He's only referred by his last name by most characters.
  • Made of Iron: Even after having his brain badly scrambled he's still able to keep going for a wile longer. Untill Cheeta slits his throat, that is.
  • Missing Mom: His mother walked out on him in order to escape his abusive father. Something that scared Kido to the point where when forced to remember it, he bursts out into Berserker Tears and starts screaming, all while wishing to see her again, regardless of how improbable it would be.
  • Muscles Are Meaningful: The most muscular brute in the Destroyale and also the only one capable of killing fully transformed Brutes with pure physical force alone as well.
  • My God, What Have I Done?: After being used as a bowling ball by Hitomi and kicked into a couple of trees, breaking them, Kido goes into trauma-induced shock, followed by One-Winged Angel, and then into Unstoppable Rage, as he goes all out on Hitomi in retaliation.
  • Nature Lover: He apparently likes nature, and becomes far more murderous when someone damages nature.
  • Nigh Invulnerable: His armor can resist most attacks like they are nothing.
  • Noodle Incident: Whatever Kido did during his first and only match as a Killing Bites participant, which resulted in him being banned from ever entering the tournament again and his permanent imprisonment in an isolation cell at the Bureau's Brute storage facility, is never elaborated upon or touched in any way.
  • Nothing Personal: His reasons to do anything are never in self-interests, acting only as the "protector of nature" whenever he does do something. Shows best whenever he kills someone, as he tries to kill them as quickly and painlessly as possible, finding no joy or reason in dragging it out longer than necessary.
  • One-Hit Kill:
    • Kills Crocodile with a single fist through his brain! And then beats the corpse to a literal pulp!
    • Punches Gorilla in half. The shot is framed such that the reader doesn't even see the hit.
  • One-Winged Angel: Once he snaps completely, he goes full-on pangolin-mode, resulting in his body bristling and Hulking Out out into an armor of sharpened knives.
  • O.O.C. Is Serious Business: When he starts hurting nature, then you know that he has completely lost it and won't stop fight until whoever is in front of him is deader than dead.
  • Parental Abandonment: His mother's disappearance from his life, which ended up traumatizing him to a great degree through his whole life afterwards.
  • Patricide: His father was the first casualty by Kido's hands, on the courtesy of a pressed Berserk Button and a baseball bat.
  • Perpetual Frowner: Kido practically have only showed one facial expression for the duration of his appearance, a bitter and sour one. Something which carries over into his battle form as well, only the expression is shown through his plates instead akin of a helmet.
  • Rasputinian Death: During the course of the Destroyal, he suffers from losing an eye, having his torso slashed up, a clawed finger through his eye-socket, a hand shoved through his mouth and out through the back of his skull and his throat cut open trice in unison. All of it absolutely necessary in order to bring him down.
  • Rolling Attack: Rather than rolling over Taiga, Kido opens his guard just enough to bait an attack and grab his arm. He then rolls around until he manages to tear the Tiger's arm right off.
  • The Quiet One: The only times he opens his mouth, is either when his Berserk Button is pushed, or acknowledging orders. The former is a major Oh, Crap! moment for whoever it's addressed to as it signals how their life expectancy is about to drop down into seconds.
  • Screaming Warrior: Once he starts reliving his childhood traumas, he won't stop screaming/roaring as he fights on.
  • Seldom-Seen Species: Second only to Brute Civet in terms of rarity regarding media exposure.
  • Tail Slap: When he grows his tail, he can use it to smash his foes like a crocodile, or a dinosaur!
  • Team Killer: If you harm nature, he will show you no mercy even if you're his teammate, just ask the Gorilla.
  • Tragic Keepsake: His pot full of yellow flowers that he tended to while imprisoned in his cell, as they are the only memento left of his mother that he can have.
  • Tranquil Fury: Doesn't raise his voice, even when he's about to pummel you to death.
  • Unstoppable Rage: When reliving his past trauma while on the battlefield, he absolutely loses his mind while continuing fighting.
  • Used to Be a Sweet Kid: Used to be a normal, scrawny, kid in his past, until he finally snapped from his father's mistreatment of the memento his mother left behind for him.
  • Wild Card: His allegiance is to nature and nature alone. Hence making him the most unreliable and dangerous Brute in the whole Destroyale as not even his supposed "teammates" are safe from his wrath if they trigger it.
  • World's Strongest Man: Without a doubt as he proves fully capable of killing fully transformed Brutes while in human form and without breaking a sweat.


     In general 
  • Outgambitted: Miyabi Sumitomo believed his chameleon assassins could easily kill the injured Hitomi and ruin Shidoh's ambitions, only for Shinozaki to kill the assassins and himself is killed by Leo.
  • One-Winged Angel: The first Brutes shown to actively start off semi-transformed but eventually going full transformation later on in their fights in rate with their fury towards their opponents rising.
  • Reptiles Are Abhorrent: They favor reptilian Therianthropes, and most of them are unpleasant to say the least.
  • Terrible Trio: A sadist, a rapist and a brute which forms the darkest level of brutality to the series to date.
  • Two Guys and a Girl: The team for the Destroyale is composed by Ryuuji, Kaede and Den.
  • Villain Ball: Kaede and Den could have killed Eruza and Hitomi several times over if they weren’t more focused in torturing and trying to rape them.
  • Wake-Up Call Boss: When compared to previous enemies, they're the first Brutes that give Hitomi actual trouble.
  • We Hardly Knew Ye: The chameleon Brutes are killed or incapacitated by Shinozaki before we get to know their names, other abilities and even their human faces.

     Kaede Kazama 

Kaede Kazama/Brute Gecko

Voiced by: Takako Honda

  • Alliterative Name: Kaede Kazama.
  • Bizarre Sexual Dimorphism: She's the first female in the story who subverts this and the Cute Monster Girl trope by turning her whole head into that of a creepy gecko.
  • The Bus Came Back: She reappears in chapter 42 as a member of Team A (The same team as Taiga and Eruza, curiously)
  • Glass Cannon: Her "Vander Slap" and gecko-physiology allows her to throw down a beating that even put Hitomi on the defensive once caught up in it, but in contrast to her other teammates, one strike is enough to put her down.
  • Leotard of Power: Wears one and unlike her teammates, she uses martial arts in tandem with her Brute abilities instead of depending on them like Cobra and Crocodile.
  • More Deadly Than the Male: She lasts longer than her male teammates at least.
  • Sadist: She clearly enjoys making Eruza suffer during their confrontation.
  • The Worf Effect:
    • She's the first person who appears to be a really bad match up for Hitomi, but Eruza comes to help. When Kaede is about to fight both of them at once, her player sends her elsewhere only for her to get knocked out in a single slash by Taiga.
    • Downplayed in the Deathval. Kaede is reintroduced by killing a boar man effortlessly but is then defeated by Haiji in a well disputed fight.
  • Wall Crawl: Thanks to her biology, she can crawl walls and even hang upside down with only her tail.

     Ryuuji Shiina 

Ryuuji Shiina/Brute Crocodile

Voiced by: Katsuyuki Konishi

  • Enemy Mine: Briefly teams up with Gorilla and Hippopotamus to take on Tiger, but that goes down the toilet when Gorilla goes ahead instead.
  • Healing Factor: His crocodile blood allows him to heal much more quickly than other Brutes.
  • Never Smile at a Crocodile: And he's an ambush predator like an actual crocodile.
  • No-Nonsense Nemesis: In contrast to his teammates, he goes straight for the kill with whoever he fights, especially if properly pissed off first.
  • Playing Possum: Pretends to be dead so he can chomp on Tiger's leg when he's distracted.
  • Tail Slap: He can grow an actual crocodile tail to smack enemies.
  • Tempting Fate: Just as he says there's no one who can kill him, the next chapter/episode Kido shows him he's very wrong.
  • The Worf Effect: After being shown trashing Okajima like a rag doll, he's killed in a single punch by Kido to show how much of threat he is.

     Den Ounuma 

Den Ounuma/Brute Cobra

Voiced by: Hiroyuki Yoshino

  • Ain't Too Proud to Beg: After everything said and done, he still has the audacity to beg for mercy when under the foot of his executioner to be. Amazingly enough, he gets it as Hitomi not only spares him, but ensures that he gets sent off to an emergency ward for necessary surgery and treatment.
  • Attack of the 50-Foot Whatever: Despite being the shortest participant in the Destroyale, his Brute form is, by good margin, the biggest one, on the courtesy of his serpent-physiology.
  • The Bus Came Back: Signs up for the Deathval and meets Hitomi on Chapter 54.
  • The Coats Are Off: Once sufficiently pissed off in a fight, he tosses off his coat and shirt before going One-Winged Angel on whoever is in his sights.
  • Eye Scream: Gets his right eye damaged by Eruza during his fight with her and Hitomi.
  • Eyepatch of Power: He got put back together but they apparently the surgeons couldn't replace his eye.
  • Flat Character: His entire characterization amounts to “Smug Snake serial rapist”. On the other hand, it does make him easier to hate. After the Time Skip, he seems to have grown out of that and becomes one of Hitomi's allies.
  • Groin Attack: Just as he's about to rape Hitomi with his hemi-penises, she rips them off.
  • Hate Sink: Half the words that come out of his mouth are Smug Snake boasting, while the other half are offenses to the female gender. From his very first appearance it’s made clear that his character was written to be hated by the readers.
  • Half the Man He Used to Be: He is ripped in half by Hitomi but as mentioned below, he survives. On the Deathtival's preliminaries, he also gets blown up to pieces while trying to restrain Nodoka and doesn't die either.
  • He-Man Woman Hater: His opinion of women is incredibly low, to say the least, considering them as "toys" for his pleasures. The sole exception to this attitude is Gecko, however, who he genuinely respects as a person.
  • Heel–Face Turn: He credits Hitomi with turning his life around, having left his old gang and returned to school. He's also taken a job working for Seira Son, and offers to team up with Hitomi when she crashes the Deathval.
  • I Call Him "Mr. Happy": He refers to his serpentine dicks as "Cobra Cannons".
  • Jerkass: Honestly, it's the nicest thing that can be said about him.
  • Mugging the Monster: He targets Hitomi, apparently unaware that Cobras are a favorite snack of Honey Badgers.
  • Not Quite Dead: Thanks to his serpent physiology, he survives being cut in half.
  • The Paralyzer: His neurotoxin can completely paralyze his opponents.
  • Power Perversion Potential: He is using his serpent physiology exactly as one would expect a serial rapist would use it.
  • Rape Is a Special Kind of Evil: He's shown to be a rapist and generally a disgusting person.
  • Reformed Criminal: During his recovery from being torn in half, he claims to have gone legitimate by leaving his old gang and enrolling in the same school Hitomi, Pure, and Tasuku attend.
  • Shoo Out the Clowns: When he arrives with Hitomi at Nodoka's battlefield, he releases a field of poison that knocks out all the camera women and several hapless background brutes. This conveniently includes Haiji and Ena, who were putting up a good fight against the megatherium.
  • Smug Snake: Literally in this case. He rants how superior reptiles are to mammals, only for Hitomi to rip him a new one once she's able to.
  • Snake People: His battle form gives him that look.
  • Took a Level in Kindness: When Hitomi meets him during the Preliminaries, he makes a point to express his gratitude to her for having changed his life. Because of her act of mercy, he's gotten his life back on track and now works for Seira Son.

     Akemi Kishimoto 

Akemi Kishimoto/Brute Horned Lizard

Voiced by: Natsume Iwasa

  • Abnormal Ammo: Shooting blood from the eyes is this both in real life and in the Killing Bites.
  • Adaptation Expansion: In the manga she's merely Miyabi Sumitomo's Sexy Secretary, but in the anime she's sent to target Hitomi and Ui alongside her sister.
  • Bodyguard Babes: She serves as this for the head of the Sumitomo Zaibatsu. Unfortunately she's too slow to react when Leo kills her boss.
  • Deer in the Headlights: After Sumitomo is killed, she tries to avenge him, only for Leo to transform in front of her, leaving her utterly paralyzed. She's lucky the lion lets her live.
  • Early-Bird Cameo: In the anime she debuts a few chapters before than in the manga.
  • No Name Given: Her twin sister isn't referred by name.
  • Tears of Blood: She weaponizes the natural ability horned lizard have of shooting those. Unlike real lizards, she can shoot them with so much pressure they essentially become liquid bullets.
  • Satellite Character: In the manga she is nothing beyond the secretary/bodyguard of the head of the Sumitomo Zaibatsu. The anime does give her a scene where she isn’t with him, but even then no information about her person is given beyond her having an incestuous relationship with her twin sister.
  • Sexy Spectacles: Although she takes them off when on a mission.
  • Twincest: The anime heavily implies she has an incestuous relationship with her sister.

     Reiichi Shidoh 

Reiichi Shidoh

Voiced by: Rikiya Koyama

  • Ambiguously Evil: Shidoh believes in forcing human evolution further, but he will use ruthless, underhanded means to qualify and will order the deaths of those who get involved without batting an eye.
  • Big Bad: He is the main antagonist of the manga.
  • Blatant Lies: He calmly explains that someone died of a heart attack, while standing a few feet from the bloody corpse. It's such a ridiculous lie that it's actually funny.
  • The Corrupter: Youko accuses him of perverting her grandfather and the entire Killing Bites competition with his hybrids. She's wrong.
  • Determinator: Flashbacks show he didn't give up in trying to bond with a young Hitomi no matter how much she scratched or bit him, until she finally grew accustomed to his presence.
  • Dragon with an Agenda: While he technically works for the Zaibatsu, they believe he intends to make the tournament his own with his hybrids. Turns out he actually intended to make the Therianthropes public knowledge and revolutionize the world.
  • Evilutionary Biologist: While he remains ambiguous on the evil part, he believes more hybrids will revolutionize humanity and force them to evolve.
  • Kick the Dog: Leaving Youko to Leo's mercies was a true dick move. So is ordering Yuuya's death, at Hitomi's hands no less.
  • Morally Ambiguous Doctorate: While creating animal hybrids is quite amoral, letting mentally unstable people take the Brute process is something no moral person would do.
  • Papa Wolf: He was willing to get almost killed by gangsters in order to protect Hitomi.
  • Parental Substitute: Seems to be the closest thing to a parent for Hitomi.
  • The Stoic: Barely expresses any emotion, save in his flashback with Hitomi.
  • Well-Intentioned Extremist: He seems to truly believe hybrids are the next step in human evolution.
  • Your Approval Fills Me with Shame: Even if his response to Youzan Mikado's praise to him for Civet's creation is humble, his visage displays perfectly what he really thinks about having his "masterpiece" Ratel roped in by the former's "Civet Wrap".

     Mai Shinozaki 

Mai Shinozaki

Voiced by: Chinatsu Akasaki

  • Big Damn Heroes: While being a hero is debatable, she did arrive just in time to save a younger Shidoh and Hitomi from some thugs who were trying to kill them.
  • Bodyguard Babes: She serves as one for Shidou, when necessary.
  • Combat Stilettos: She makes a point of kicking ass in her office attire, including a nice pair of high heels.
  • Crouching Moron, Hidden Badass: She acts like an airheaded Large Ham when announcing Killing Bites. Under it, she is ruthlessly efficient in combat and very likely one of the strongest characters in the entire series.
  • Kick Chick: Her fighting style appears to involve swift and powerful kicks.
  • Large Ham: When acting as presenter of the Killing Bites tournament, she turns into one of this.
  • Obfuscating Stupidity: When the cameras aren't rolling, she drops her vapid, silly persona and can turn extremely serious and analytical in the blink of an eye.
  • Offscreen Teleportation: She somehow leaves the cruise ship and arrives just in time to save the injured Brutes from the chameleon assassins without anyone noticing until she was already there.
  • Sexy Secretary: She's also Reiichi's assistant, and if the anime ending doesn't lie, a bombshell as well.
  • The Un-Reveal: Her Beast Form is not revealed at all, with things taking place just off-camera and only a faint glimpse of her clawed hand in the shadows.

Other Characters

     Oshie Nodoguro 

Oshie Nodoguro

Voiced by: Sayaka Harada
A random girl who is head over heels for Hitomi, but is Not a Therianthrope.
  • Animal Motifs: Despite not being a hybrid, Oshie uncannily acts like the Greater Honeyguide, a bird that's used as guide by honey badgers. Ironically, even the reveal of her being unfit to be a Brute comes with a honeyguide funfact.
  • Butt-Monkey: Repeatedly gets in trouble while trying to get close to Hitomi and her side-story ends with the reveal that she's incompatible with the hybridization process. When Oshie gets a proper but brief introduction in the story, it is when Yuuya, a crow, acts like more of a honeyguide than her by baiting Hitomi towards the Deathval.
  • Entertainingly Wrong: When she sees Hitomi's transformation from afar, she thinks it's a cosplay.
  • Extreme Omnivore: A very downplayed example, but like how Honeyguides eat beeswax and larvae, she can eat a plastic decoration, despite tasting horrible.
  • Hollywood Tone-Deaf: She's a terrible singer.
  • Muggle Best Friend: Is not a Brute and was completely unaware of Hitomi's other side. She's also the closest thing Hitomi has to a friend.
  • Recurring Extra: At the end of the first ten volumes and each anime episode, we see a brief segment of her interactions with Hitomi. She's finally introduced in the story proper during chapter 55... in a single panel.
  • Yandere: In an omake, she tricks Yuuya into approaching a group of delinquents so he can't "date" Hitomi anymore.

Characters in Part 2

Team Z

     Pure Inui 

Pure Inui/Brute Beagle

Voiced by: Minami Tanaka

  • 10-Minute Retirement: After Tasuku is killed by Nodoka, Pure breaks down in despair and has to be repeatedly encouraged by both Yuuya and Nunuupi to pull herself together and put Nodoka down while Hitomi is distracting the beast.
  • Badass Adorable: She's basically a puppy in human form, and with the right drive she can be just as badass.
  • Contrasting Sequel Main Character: Pure is innocent, incredibly social, and a kind person overall. This heavily contrasts her with the abrasive, antisocial Hitomi. Their animals also contrast, as a Beagle seems very mundane in comparison to the legendary Honey Badger.
  • Curtains Match The Windows: She has brown hair and eyes.
  • Cute, but Cacophonic: Like any Beagle, she's adorable and loud. Taking to a weaponized level, when facing other Brutes with their enhanced hearing.
  • Cute Little Fangs: She is shown to have them even when she's not transformed.
  • Deadly Lunge: Whether she's giving hugs, chomps or just avoiding attacks, Pure often lunges from out of nowhere at people.
  • Dogs Are Dumb: She isn't the brightest, and is often easily fooled by others because of her trusting nature. And that's despite her instincts in the form of her dead pet Nunuupi always trying to keep her out of trouble.
  • Emergency Transformation: She received the hybridization surgery to save her life, after being run over by a truck. Unfortunately, her beloved pet dog was used as the surgery's base.
  • Everything's Better with Spinning: Frequently spins and rolls while dodging or attacking, which is accompanied by circular speed lines.
  • Extreme Doormat: Explicitly because of her animal nature. Unity is everything to dogs, so she tries wholeheartedly to reconcile Hitomi and Nomoto even while the former is crushing her head into the dirt.
  • Fastball Special: During the battle against Nodoka, Yuuya carries Pure high into the air and then launches her like a high-speed projectile.
  • Foil: Pure is nearly as reckless as Hitomi but unlike her she's shaped like a friend and is very idealistic.
  • Heroes Love Dogs: The heroine of Part 2, and a dog-lover that ended up fused with her beloved pet.
  • Heroic BSoD: When Pure and Nunuupi start having too many arguments over his advice, he stops appearing for a while. Then it turns out Pure has no idea how to fight alone, and she starts getting beat up and then moping about while Nodoka tries to help. Pure is cheered up by Tasuku's and Yuuya's arrival, but this is followed by disaster as Nodoka goes crazy and Pure becomes indirectly responsible for Tasuku getting ripped apart by Nodoka, as she had refused to kill the Megatherium. A distraught Pure is carried again by Yuuya and begrudgingly finishes Nodoka off, and then tries to confort the sloth in her final moments. Afterwards, Pure spends the night in grief, talking to delusions of Nunuupi and Tasuku before starting to cry and scream at the sky.
  • Killer Rabbit: Tasuku and the audience are amused by her adorable Brute form...right up until Pure launches at her with fangs bared. Tasuku ends up on the defensive, shocked by her "cute" opponent's speed and aggression. As the narration points out, people forget that the beagle was originally bred as a hunting dog.
  • Last Episode, New Character: She appears in the epilogue of the final episode, teasing the second half of the series.
  • Let's Get Dangerous!: Pure is sweet, adorable, and generally underestimated by other Brutes. That doesn't stop her from being a tough opponent when the right switch is flipped.
  • Make Me Wanna Shout: Beagles are infamous for being loud, and for good reason. When she's cornered, Pure begins baying at full volume in an enclosed space. The noise stuns her attacker long enough for Pure to make her escape, and startles numerous other Brutes in the process.
  • Man Bites Man: Like a dog, she mainly fights using bites.
  • Maybe Magic, Maybe Mundane: Pure used to be able to talk with Nunuupi and his ghost is present in scenes where she is unconscious as if he's really supernatural, but ultimately both of them admit he's really a delusion for coping with her loneliness and that her being able to turn into a beagle-girl is just a Contrived Coincidence. This does not stop her from imagining Nunuupi, Tasuku and Nodoka hanging out with her all the time.
  • Nice Job Breaking It, Hero!: When Nodoka turns into an insane rampaging Megatherium, Pure tries her best to defeat her without dealing serious damage, going as far as holding back when presented the perfect killing chance by Yuuya and getting in Hitomi's way when she knocks Nodoka out. This backfires horribly when Nodoka cuts Tasuku in pieces.
  • Parental Abandonment: Born from parents who "wanted to make children but didn't want to raise them". She was abandoned at the age of 1 and raised on some orphanage where she only had her dog Nunuupi for company.
  • Punny Name: "Inu" means Dog.
  • Reused Character Design: Resembles Turis Flag and Alice Fujii from the author's previous works. Some situations Pure is put in are even clear call-backs to the latter girl.
  • Right for the Wrong Reasons: She notices that Yuuya has a personal grudge against Hitomi, and therefore concludes they must be exes. Her reading of the situation is not entirely inaccurate, but she manages to embarrass them both enough to break the stalemate and ends up telling others about the "lovers' quarrel".
  • Save the Villain: A recurring thing with her. She keeps Taiga from killing Ena, protects Moe from Nodoka's rampage and refuses to follow Yuuya's orders to tear through Nodoka.
  • Shoot the Dog: Pure is forced to kill Nodoka after her attempts to be merciful indirectly get Tasuku killed.
  • Speaks Fluent Animal: She was able to talk with Nunuupi as a child, and he'd tell her it was strange and that others would look down on her for it. It isn't shown if she can talk to any other animals, though.
  • Spell My Name with an "S": Her name is alternatively spelled as "Pyua". Her teacher also misreads the kanji for her name as "Jun".
  • Spirit Advisor: She "sees" the ghost of her pet Beagle sometimes, and gets advice during difficult moments.
  • To Be a Master: Wants to become the Killing Bites champion to honor Nunuupi's memory.
  • Trauma Conga Line: Pure wins the Deathtival's preliminaries, but feels responsible for Tasuku's death and is forced to kill Nodoka. She has a Lonely at the Top moment while trying to reassure herself that she can project Tasuku around the same way she does with Nunuupi, and spends the whole night crying.
  • Unskilled, but Strong: Pure did train herself for combat from an early age, but she is extremely teamwork-minded. She can fight well when listening to Nunuupi's advice and goes into a highly dangerous trance when Yuuya whistles commands at her, but without any allies she becomes helpless.

     Tasuku Kuroi 

Tasuku Kuroi/Brute Tasmanian Devil

  • The Ace: A talented up-and-comer, Tasuku is hailed for having the potential to be the next Ratel.
  • Bare Your Midriff: Her outfit consists of a strapless bra and a low-slung skirt, leaving her stomach completely exposed.
  • Big Damn Heroes: At the Deathtival's preliminaries, Tasuku meets back with Pure to help her and Nodoka against Team V. Trouble is, Nodoka does not welcome her help...
  • Bizarre Sexual Dimorphism: Eventually subverted as Tasuku fully transforms her head to fight against Nodoka and Hitomi.
  • Combat Pragmatist: She's not above pretending to be helpless and using low blows to get the advantage.
  • Dark Is Not Evil: She looks terrifying, but isn't nearly as bad as she seems.
  • Decoy Protagonist: After having a healthy amount of character depth and development in the second arc, she is sliced into two by Nodoka and is presumed to die instantly.
  • Deer in the Headlights: Tasuku talks a big game, but when faced with her first serious battle she hesitates for long enough that Pure fights in her stead. When Hitomi acknowledges Pure while acting like Tasuku's not even there, Tasuku figures she's got to work on her confidence.
  • Eerie Pale-Skinned Brunette: She's a typical goth girl, with pale skin that darkens when she transforms.
  • Foil: Frequently gets compared to Hitomi due to her abilities and ferocity, but is a little more approachable and more prone to getting cold feet when things really get rough.
  • Hades Shaded: Her skin darkens when she transforms into her Beast form.
  • Half the Woman She Used to Be: Tasuku gets blasted to pieces at chest-height by a sneaky diagonal slash from Nodoka and is presumed to have died instantly.
  • I Just Want to Be Badass: Tasuku puts on a fierce front for her self-confidence issues. She tends to hold back against her targets, regrets not having the courage to stand up for other people and feels inadequate in comparison to Pure and Moe. To change herself, Tasuku underwent Shidoh's gene therapy and took Hitomi as a role model after he showed footage of the ratel's ultra violent and fearless achievements during the Destroyale.
  • Jerk with a Heart of Gold: For all her aggression, she ends up won over by Pure's efforts to befriend her.
  • Last Episode, New Character: She appears in the final seconds of the anime, teasing the next arc of the series.
  • Lonely Rich Kid: Her family is wealthy, but because her parents were always away at work, she developed her delinquent persona to compensate her loneliness.
  • Mighty Roar: Whenever she's cornered, Tasuku attempts to paralyze her opponent with the Tasmanian Devil's infamous shriek.
  • Nightmare Face: The Tasmanian Devil is notable for its ability to open its mouth 70 - 80 degrees. Tasuku is similarly able to open her jaws far beyond the norms of human physiology, which is incredibly disturbing to witness.
  • Now, That's Using Your Teeth!: When Eruza attempts to rip Tasuku's head off with her huge cheetah paw, Tasuku nearly swallows her arm. It's just so crazy Eruza actually jumps back in surprise and can't help but compliment her.
  • Punny Name: Her name seems to combine the words "tasmanian" and "akuma".
  • Sacrificial Lion: Despite being one of the protagonists of the second arc, Tasuku is randomly killed by Nodoka just as she's managing to prove her worth by overwhelming Hitomi. Her death deeply impacts Pure, who is forced to kill Nodoka and begins taking Killing Bites seriously as the death game it really is.
  • Tattoo as Character Type: She's heavily tattooed, as fits her aggressive nature. Her cheek tattoo also doubles as a nod to tasmanian devils being afflicted with facial tumors.
  • Took a Level in Badass: Through the Deathtival's preliminaries, Tasuku is able to show off her strength and builds the confidence to challenge veterans like Eruza and Hitomi. She actually fights Hitomi's Origin form on equal grounds and would have defeated her if not for...

     Haiji Gotoh 

Haiji Gotoh/Brute Ibex
A lonely girl who happens to have befriended Hitomi in the past.
  • Animal Eyes: When transformed, she gains the unusual pupils of a goat — and the enhanced field of vision it grants.
  • Art Major Biology: Actual goats have a wide line of sight because their eyes are on the sides of their heads, and not because their pupils look funny. Haiji doesn't fully transform her head during the Deathtival's preliminaries, but the story gives the exaggerated trivia nonetheless.
  • Big Damn Heroes:
    • By defeating Kaede, she disqualifies Team A from the Deathval's preliminaries and this unintentionally prevents her teammates from getting their asses kicked by Taiga and Eruza.
    • Catches up with the rest of the cast at the Deathval by keeping Pure and Moe from getting crushed under Nodoka's claw.
  • Connected All Along: She actually knew Hitomi when they were children.
  • Deus Exit Machina: Haiji and Ena happen to get knocked out by Den's poison mist when he arrives with Hitomi, leaving Pure and Tasuku as the only ones to confront Hitomi and continue to fight Nodoka. This also keeps Haiji from interacting with her old friend.
  • Fauns and Satyrs: Her transformation makes her look like the mythological creature.
  • Going Commando: She takes off her skirt to fight during the Destroyale. Luckily her fur keeps everything covered.
  • Heavy Sleeper: Frequently half-asleep in class even though she sleeps properly and early at night.
  • Horned Humanoid: Her pigtails transform into an enormous pair of curved horns, which are her primary weapon.
  • Let's Get Dangerous!: Haiji appears lazy and is bad at physical education, and yet she practically carries her team on her back during the Deathval's prelims.
  • Lightning Bruiser: Like a real goat, Haiji pairs incredible agility and speed with the ability to endure heavy blows and throw larger opponents around with her horns.
  • Mega Twin Tails: She wears long pigtails in her human form, which become horns in her beast form.
  • Not So Different: Haiji and Tasuku don't realize they get on each other's nerves because they're both trying to be like Hitomi.
  • Punny Name: Her last name sounds very similar to "Goat".
  • Smug Super: Whenever she encounter an enemy, Haiji runs away... just to see if they can catch up and be worth her time.
  • Use Your Head: Her horns allow her to deliver a devastating head-butt, just like a real Ram.
  • Wall Crawl: She not only scales a sheer wall using her hooves, but takes on fellow wall-crawler Gecko in the process.

Team E

     Ena Haibuchi 

Ena Haibuchi/Brute Hyena

  • Action Girl: As expected of a Hyena, she's easily one of the strongest Rookies when push comes to shove.
  • Big Damn Heroes: Ena comes to the rescue during the battle against Nodoka, effectively turning the tide of the battle by latching on to the giant's neck. Her assistance gives Pure's team the help necessary to start dealing real damage to the giant.
  • Bitch in Sheep's Clothing: Her standard trick is to appear cute and harmless, right up until her victim's back is turned.
  • Combat Pragmatist: Like real Hyenas, she's an exceptionally opportunistic fighter that considers anything fair game in a battle. She wears a crew member's costume to lure Pure in to a trap, but later offers to help her against Tiger solely because it gives them a better chance to survive.
  • Deus Exit Machina: Ena and Haiji happen to get knocked out by Den's poison mist when he arrives with Hitomi, leaving Pure and Tasuku as the only ones to confront Hitomi and continue to fight Nodoka.
  • Double Standard: Rape, Female on Female: Averted completely. Her attack on Pure is handled exactly like any of the male-on-female assaults in the series, establishing her as a vicious enemy.
  • Early-Bird Cameo: She appears in Chapter 39 at Carrot Field, as one of several Brute-hopefuls that will later take part in the preliminaries.
  • Easily Forgiven: Other than referring to her as "that Pervert", Pure doesn't seem to hold any kind of grudge against Ena for trying to rape her.
  • Embarrassing Nickname: Pure nicknames her "Pervert", and continues calling Ena that even when they're working together. Others quickly adopt the nickname, resulting in an entire crowd cheering for "Pervert" while Ena blushes furiously.
  • Enemy Mine: When faced with a clearly-overwhelming opponent, Ena is quick to suggest working as a pack to overcome their common enemy. Rather than being cowardly or deceptive, in these cases she actually works hard to create opportunities for Pure to land a decisive strike.
  • Face of an Angel, Mind of a Demon: She has the looks necessary to convincingly pass for a wholesome, innocent Idol Singer. But her pretty face conceals a vicious serial rapist that enjoys dominating other women.
  • Game Face: When pretending to be part of the KB crew, she has a normal human face with transformed limbs and ears. After revealing her true nature, her face transforms further to make usage of her species' infamous bite.
  • Heinous Hyena: She's a vicious, deceptive rapist.
  • Hermaphrodite: Spotted Hyenas were mistaken in the past for this, because the female's genitals form a pseudo-penis. Brute Hyena is no exception to this, as she's happy to show Pure.
  • Man Bites Man: As a Hyena, she has an incredible bite and tends to attack by latching on to her victims and refusing to let go. Tiger makes to take it without serious injury, but transforming even further allows Ena to tear massive chunks from Nodoka's giant form.
  • Mugged for Disguise: She attacks a member of the KB crew, and steals her dress to fool the other Brutes.
  • Nightmare Face: She's capable of transforming even further, a process that gives her a longer, thicker neck and massive jaws.
  • Oh, Crap!: She's utterly shocked and terrified when she realizes she's stumbled upon Tiger's hunting ground.
  • Psycho Lesbian: She enjoys having her way with pretty girls, taking advantage of her.....unique Brute biology.
  • Punny Name: "Haibuchi Ena".
  • Rape Is a Special Kind of Evil: She attempts to rape Pure, and is shown to be a cruel and conniving enemy.

Team V

     Moe Hanzaki 

Moe Hanzaki/Brute Salamander

  • Attention Whore: Moe was once a normal gloomy lonely girl until an injury that broke her arm got the attention and pity of her classmates. She grew obssessed with getting attention from all kinds of self-harming stunts even as reactions turned into disgust and rejection.
  • Badass Back: Can fire bursts and beams of poison from her back.
  • Beware the Silly Ones: Signs in for the Deathtival to get beaten up and is dominated by Eruza, but her regeneration and poison abilities make her very valuable to her teammates anyway.
  • Early-Bird Cameo: She was first seen alongside other Brutes in chapter 39, but her name and beast form weren't known until chapter 45.
  • Emergency Transformation: She received the hybridization surgery to save her life, after hurting herself a little too much from jumping off a building.
  • Expy: Any personality traits of Gokiburi from Arachnid Eruza doesn't have ended up with this amphibian.
  • Good Thing You Can Heal: Regeneration is Moe's whole thing, so even when her entrails are leaking out or when she gets ripped in half you can't count on her being down for good.
  • Half the Woman She Used to Be: Moe is finally incapacitated when she gets clawed in half by Nodoka, but even then she still doesn't seem bothered at all and gets put together later.
  • Healing Factor: She regenerates almost instantly, and really enjoys the process.
  • The Immodest Orgasm: When particularly pleased, venom bursts out of her back to the extent that she's sent flying while screaming in ecstasy.
  • Loners Are Freaks: Moe tells Pure people can have friends or family and still be unable to relate to any of them. As such, although Moe is amicable she is awfully comfortable with being disliked by others.
  • Not the Fall That Kills You: Dropping herself from some building is what forced doctors to transform her.
  • Oh, Crap!: Actually gets shocked when Eruza isn't affected at all by her poison. And later when she thinks she beat Nodoka but then gets chopped in half from out of the blue.
  • Peek-a-Bangs: Her hair usually covers her right eye.
  • Poisonous Person: Like several salamanders, she can use poison as a defense mechanism.
  • Self-Harm: She began by cutting her wrists and went downhill from there.
  • Stone Wall: Moe's battle plan is making a nuisance out of herself and tanking damage until she climaxes and blasts the opponent with poison.
  • Too Kinky to Torture: An extreme masochist, she enjoys every moment of receiving what should be fatal injuries and only retaliates with bursts of poison to keep from actually getting killed. And even then it's more like she does it as a result of having The Immodest Orgasm.

     Gou Arimori 

Gou Arimori/Brute Anteater

  • Delinquent Hair: He sports a pompadour in human form.
  • Early-Bird Cameo: He and the rest of his team debuted in chapter 35, but his name and Brute form weren't known until chapter 49.
  • Inelegant Blubbering: He's one of the Carrot Field people left most devastated by Tasuku's death and, after being kept from taking his frustration out on Pure, starts crying profusely on the floor.
  • The Lost Lenore: He was actually in love with Tasuku, but never confessed his feelings. As such, he takes her death the hardest out of everyone.
  • Sleeves Are for Wimps: Wears a sleeveless vest.

     Lambert Ogata 

Lambert Ogata/Brute Kangaroo

  • Afro Asskicker: Has a notorious afro, and it stays even in kangaroo form.
  • Boxing Kangaroo: Just like a kangaroo, he can give a nasty kick, but he can wrestle as well.
  • Early-Bird Cameo: He and the rest of his team debuted in chapter 35, but his name and Brute form weren't known until chapter 50.
  • Shout-Out: Holds Pure in a headlock, like that one 2016 incident in Australia. Another scene is a double-page spread of him kicking Pure in the stomach — a Production Throwback to Alice getting beaten up by Kamadouma in Arachnid.
  • Token Minority: The first black character of note in the series.

Team G

     Seiichi Todoroki 

Seiichi Todoroki/Brute Walrus

  • Mugging the Monster: He had no idea the girl he was trying to ambush was Hitomi, who had become something of The Dreaded by all the other Brutes.
  • Top-Heavy Guy: His flippers and head look huge when compared to the rest of his body.
  • We Hardly Knew Ye: Introduced quickly, and defeated just as quickly by Hitomi. We later see him at Carrot Field, and he gets KO'ed in a single page.
  • Wily Walrus: He's a walrus and a Brute.

Other Characters

     Nodoka Uzaki 

Nodoka Uzaki/Brute Sloth
A lonely girl who, like Hitomi, is also a part of Shidoh's experiments.
  • Amazonian Beauty: She's a muscular woman that towers over everyone else.
  • Arc Villain: The story develops Building-sized Nodoka as a Suspiciously Similar Substitute for Hulking Spikeball Kido. While not villainous, her mental state and powers are very unstable and she ends up attacking Pure and Tasuku for misguided reasons. She even chops Moe in half like Kido had done to Shouta, and takes a limb from Hitomi while fighting her.
  • Attack of the 50-Foot Whatever: Nodoka is able to transform into a titanic megatherium once she gets worked up.
  • Bizarre Sexual Dimorphism: Unlike other female hybrids, her Beast form involves transforming up upper body into that of an animal.
  • Boobs of Steel: Her huge mammary glands are noticeable even in megatherium form, and she packs the biggest punch seen so far in the series.
  • Disproportionate Retribution: Pure has other friends? She must die!
  • Eye Scream: Like Kido before her, Nodoka gets her right eye goughed out by Hitomi. This incapacitates Nodoka for a while, as even as a Megatherium she has low tolerance for pain.
  • Friendless Background: She's always been treated badly due to her strength and appearance, so she's moved to tears when Pure treats her with kindness.
  • Gentle Giant: Massive both in height and build, she's introduced rescuing Pure and doing anything she can to protect her. However...
  • Go Out with a Smile: Nodoka only regains her senses when she's disemboweled by Pure, but dies happy to know she misunderstood her and Tasuku, and that Pure really did care for her.
  • Green-Eyed Monster: A beaten-up Nodoka becomes infuriated when she hears Pure saying Tasuku, her other friend, is going to help them out against Moe's team. Feeling betrayed, she chops away Moe's entire team in a fit of Unstoppable Rage and glares daggers at poor Pure and Tasuku...
  • Gutted Like a Fish: Pure drills through her body, ripping Nodoka open from shoulder to groin with a single attack. It's one of the most graphic kills in the series, with Nodoka's intestines and other vital organs starting to spill out of the wound as she dies. Pretty sure that's her liver hanging over there.
  • Hero Killer: After losing an eye, Nodoka collapses on the floor and certain two people start fighting on her back. A while later, she finally takes a swipe at the figures and gets one, Tasuku chopped to pieces.
  • Humanity Ensues: Nodoka believes she's been adopted by Shidoh as a child and then granted Sloth powers. In reality, she was originally an actual sloth who was abnormally big for her age. With his experiments, Shidoh and his team granted her the ability to turn into a Megatherium and then a human form in the hopes she'd have a mind capable of controlling such power.
  • Mighty Glacier: In her sloth form Nodoka packs a punch but lacks stamina and ends up overwhelmed by Moe's team. Her megatherium form is another story.
  • One-Winged Angel: First she turns into an extinct giant animal. Then she gains an appearance similar to Hitomi's Origin form.
  • Super Prototype: Nodoka is the latest experiment, an animal turned into a hybrid with the intention of creating new Brutes wielding the powers of extinct mega-fauna.
  • This Was His True Form: Nodoka reverts to her original sloth form when she passes away.
  • The Unfavorite: Implied, as she shares a surname with Hitomi (and Shidoh) but has never met her "sister". In reality, Nodoka is Shidoh's latest experiment — an ordinary Sloth given human form as a Hybrid, and then given the power of the ancient and extinct Megatherium. The Bureau has already accepted the possibility of Hitomi being killed, especially if doing so demonstrates the power of this new technology.
  • Unskilled, but Strong: She has very little experience in fighting, but compensates with her size and sheer power.
  • With Great Power Comes Great Insanity: She transforms into a Megatherium out of the mental trauma she was suffering while getting beaten by Gou, Ranberto and Moe. Once that happens, she forgets what is going on or who Pure is, and is reduced to wanting to kill anyone who comes near. Eventually she recalls her true origins and gets even more crazy and powerful.
  • The Worf Effect: Nodoka's first act as a Megatherium is instantly demolishing the team that had beating her up. Then a lot of other Brutes home in to where she is and nearly all of them get stomped into paste in about ten pages, further establishing her threat level.

     Riku Oogami 

Riku Oogami/Brute Wolf

  • Glass Cannon: His age means he cannot fight for prolonged periods of time, but he's just as powerful as any other Brute.
  • Obfuscating Stupidity: Doesn't look like much and brutes with a keen sense of smell feel nothing but weakness coming from him, but Riku is just pretending.
  • Punny Name: "Oogami" sounds an awful lot like "Okami", meaning Wolf.
  • Smoking Is Cool: Introduced smoking a cigarette.
  • Our Werewolves Are Different: He's a Brute and a werewolf.

     Tepei Saino 

Tepei Saino/Brute Rhino

  • Combat Pragmatist: Charges at Tasuku the moment her back is turned, not even waiting for the referee to signal a start.
  • Graceful Loser: He accepts his defeat against Tasuku surprisingly well, despite the cheap shot.
  • Groin Attack: Tasuku does this to defeat him, getting around his tough hide. It is only fair given how he was previously bragging about stomping on her womb.
  • Know When To Fold Them: When he tried to approach Hitomi during a party, he quickly noticed how much power and killing intent she had, so he wisely backed away.
  • Punny Name: "Sai" means rhino.
  • Rhino Rampage: His signature move, charging headfirst at his opponent.

     Amamiya Zenzaburou 

Amamiya Zenzaburou/Brute Frog

  • Frog Men: In his Beast form.
  • I Have You Now, My Pretty: Gains Pure's trust, then tries to molest her when she's unconscious.
  • Poisonous Person: He's a Japanese Tree Frog, with a neurotoxin-laced mucus that paralyzes other Brutes.
  • Rape Is a Special Kind of Evil: A gross, vile man that uses his position to take advantage of young women.
  • Reptiles Are Abhorrent: The Amphibious variant of the trope. He's a gross, perverted Frog man that preys on young women.
  • Screw the Rules, I Make Them!: He works for the Bureau, and uses his authority to cover up his crimes. When Tasuku attacks him, he threatens her with his position. (Too bad for him that her backer has better connections...)
  • You Would Make a Great Model: He uses his position in the Bureau to approach young women, and offer them assistance in becoming a Brute. Once he lures them to a "training facility", he knocks them unconscious with his neurotoxin and rapes them.

     Igawa Chiyomatsu 

Igawa Chiyomatsu/Brute Giraffe

  • Badass Teacher: A powerful Brute, who takes his role as a teacher very seriously. Once his students become Brutes, he makes it a point to prepare them by beating them to a pulp.
  • Casual Danger Dialog: Even in the midst of battle, he's still very much a teacher. After Pure bites him on the neck, he takes the time to provide her with feedback on her attack.
  • Genial Giraffe: Zigzagged. He's usually all smiles, and comes across as very concerned about his students. But he's also a terrifying opponent that will brutalize rookie Brutes to make sure they're ready for the real thing.
  • Ground Pound: Like a real Giraffe, his primary method of attack is to trample his smaller opponents.
  • Know When To Fold Them: When Ratel threatens to get involved in the match, he declares himself the loser and ends the fight to protect Tasuku.
  • Magic Pants: When he transforms, his slacks are the only thing to survive with only minor damage from his hooves.
  • Sink-or-Swim Mentor: He treats rookie Brutes with no mercy, stating this is the only way to prepare them for the real Killing Bites. If they can't manage against him, there's no chance for them to survive in a real competition.

     Deshi Murata 

Deshi Murata

The enthusiastic announcer at Carrot Field.
  • Bit Character: Only appears during the battles at Carrot Field, and isn't confirmed to be a member of JTK 48.
  • Cat Girl: A bobcat girl.
  • Punny Name: "Deshi" means "apprentice" and Murata is the manga's author, so she was likely designed by one of his assistants.

     Rina Satou 

Rina Satou/Brute Siberian

  • Badass Adorable: She's an adorable idol, but her reputation at Carrot Field suggests she's a strong Brute.
  • Cat Girl: Marketed for being a Cat Girl, and one as popular and beautiful as the Siberian.
  • Constantly Curious: She's marketed as endlessly curious, and Tasuku states she's a bit odd in her interests and curiosities.
  • Hidden Depths: Her public persona is as cute and bubbly as expected of an Idol, but she's actually part of Tasuku's gang at Carrot Field. Pure is surprised to see her drinking beer and slumming with the other Brutes, wondering if she'll get in trouble for it.
  • Idol Singer: A member of the popular idol group JTK 48.
  • Silk Hiding Steel: As an Idol, she's thought of as fragile and cute like the other members of JTK 48. But Ui suggests her as one of the Brutes for the final tournament, stating she's actually quite strong.

     JTK 48 

JTK 48

  • Bland-Name Product: Obviously based on real-life group AKB48.
  • Cat Girl: Branded as a "Cat Girl Idol Group", with each girl being some type of feline hybrid. The ones identified are either domesticated breeds or small wild cats.
  • Fragile Speedster: Their high agility and speed make them ideal camera crew for the competition, even though none of them have any combat abilities. Their job, as such, is to observe the Brutes in action while staying out of their way for their own safety.
  • Idol Singer: An extremely popular Idol group formed by the Bureau, working to promote Killing Bites.
  • Loads and Loads of Characters: There are so many girls in the group, keeping track of their roster is extremely difficult. Brute Hyena exploits this to disguise herself as one of them.

Characters in Part 3

     Koyomi Uzaki 

Koyomi Uzaki

The third and youngest, but no less crazy and dangerous, Uzaki sister.
  • Ax-Crazy: She goes from being polite and bashful to enraged and murderous on the drop of a hat, and is powerful enough to have curb-stomped Taiga with so far unrevealed abilities.
  • Expy: Her character and actions so far are very reminiscent of Dinoponera from Arachnid, though her hairstyle resembles Kabutomushi's.
  • Killer Rabbit: She's a shy 12-years old girl, and yet she is said to be stronger than Yuugo. Indeed, when Taiga attempts a backstab on Koyomi, she suddenly makes a freaky Death Glare at him and whatever she did offscreen sent him straight to the hospital.
  • No Sense of Personal Space: Gives Pure an uninvited kiss on the lips at one point.
  • Smug Super: In her introduction scene, despite acting very polite and embarrassed she tells Taiga to his face she'd rather not transform so she won't hurt him too badly.

     Agito Shiina 

Agito Shiina

The leader of the Second Municipal school's cheering squad, and brother to Ryuuji from the first arc.

     Dango Samejima 

Dango Samejima/Brute Jaws

A member of the Second Municipal school's cheering squad.
  • Achilles' Heel: Like with a real shark, his snout is extremely sensitive to damage. Pure's headbutt knocks him down, writhing in pain the same way a diver can ward a shark off by punching them.
  • Logical Weakness: Like a real shark, he's a powerhouse that leads with his most vulnerable part and cannot see when he attacks. All it takes to defeat him is Pure having the guts to counter his strike with a headbutt to the nose.
  • Revenge by Proxy: He wanted to duel Tasuku after the Deathtival's preliminaries as payback for her beating up his fellow delinquents, but since she's unavailable he takes his anger out on Pure instead.
  • Threatening Shark: Transforms into a great white shark.
  • Younger Than They Look: He's a tall muscular man with Hotblooded Sideburns, facial hair and a sick diagonal scar across his face. Pure can't believe he's a high-schooler.
  • The Worf Effect: Pure isn't scared of his massive shark form at all, which contrasts with Agito intimidating her afterwards with nothing but a handshake.

     Tomo Arimori 

Tomo Arimori/Brute Tamandua

  • Cuteness Overload: She's unbearably cute, both as a human and in her brute form. Pure is so overwhelmed she can't do anything but squeal and hug her.
  • Shorttank: She tries to style herself after her older brother, and act tough like the other Brutes at Carrot Field.


How well does it match the trope?
