Hitomi Uzaki/Brute Ratel

Voiced by: Sora Amamiya
https://static.tvtropes.org/pmwiki/pub/images/hitomi.png

  • Amazonian Beauty: The anime gave her a well toned physique and the manga gladly followed suit.
  • Anime Chinese Girl: Averted in that she lacks the usual traits of this trope. However, her background reveals that she's originally from China and was known among the locals as Chusheng prior to being taken in by Shidoh.
  • 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.
  • Battle Strip: She nearly always strips down to her underwear when she gets ready for a fight.
  • Berserk Button:
    • She loves to fight, but she can be quite comically riled should you put a hand near her sweets.
    • She's prone to hitting Nomoto whenever he acts protective towards her.
  • Big Damn Heroes: Hitomi loses the King of Killing Bites on her first match and goes Out of Focus for some time, but is asked to support a helpless Pure against Koyomi when the tournament starts going off the rails.
  • Blood Knight: She loves fighting, even when the fight involves her getting punched by a lion.
  • Born Winner: Hitomi's powers aren't the result of surgery like the other Brutes. Rather, she is an Origin Beast — born with her powers and capable of taking on a more powerful secondary form.
  • Brutal Honesty: She's quite rude and blunt. When Pure begs Hitomi for advice on how to beat Haiji, she just answers Pure won't with a bored look on her face.
  • 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.
  • Character 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. From then on, the motto becomes an in-universe meme.
  • Chainmail Bikini: She fights in her underwear and her tough honey badger hide only covers her back, arms and legs.
  • Death Glare: Known for making ear-to-ear grins with her eyes very wide open when she's excited about a fight.
  • 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.
  • Easily Forgiven: Yuuya tries to play tough after revealing his survival from Hitomi's assassination attempt but ultimately can't bring himself to hate her for following Shidoh's orders and takes pains to reconcile with her despite how bitchy and abusive she tends to be towards him.
  • 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.
    • Her Lack of Empathy for anyone who isn't Shido. Shido is the only one who she shows any form of respect and couldn't give a damn about anyone else, not even her allies. As a matter of fact, part of the reason why she was ordered to kill Yuuya was to know what it was like to lose something she began caring for. Given her reaction, it worked swimmingly.
  • 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, Hitomi 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.
  • Handicapped Badass: Hitomi loses limbs twice throughout the series and on the second time her reattached left arm is still paralyzed when she needs to fight again. She never lets any of that bother her and still finds ways to use her severed or disabled limbs as weapons.
  • 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.
    • Haiji drops Hitomi head-first from a massive height and defeats her by knockout... as opposed to, you know, turning her into mush from such a hit. It even ends up fixing her then disabled left arm!
  • Major Injury Underreaction: Hitomi cares little for enemies chopping her limbs off. She does scream in pain when Kido chops her arm off, but soon enough she's tossing it on his eye. And later when Nodoka claws it off again, Hitomi reacts with excitement from seeing an opening for a counter attack.
  • 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.
  • Now That's Using Your Teeth!: After Koyomi was shown to be able to slice through people like butter, Hitomi casually bites a claw meant to behead her on reflex.
  • 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.
  • Rescue Romance: Hitomi starts warming up to Yuuya for real after he saves her from Nodoka and confesses he still cares for her a whole lot.
  • 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.
  • Smug Super: She takes the whole "honey badgers aren't afraid of anything" thing to extremes and has full confidence that she can take on everyone on her own. When she really doesn't care about a given opponent, she goes as far as to pretend to not notice they're there.
  • 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. Even after growing to trust Yuuya, she is still extremely defensive and prone to getting offended and slapping the poor guy for just about anything.
  • Undying Loyalty: She acts much sweeter around her adoptive father Shidoh, who saved her life and raised her, and was willing to assassinate Yuuya for him despite not liking it.
  • 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.
  • Worf Had the Flu: Hitomi loses to Haiji at the King of Killing Bites tournament while her left arm is disabled, and is so ruthlessly beaten she doesn't get to use her fully powered form.
  • Worthy Opponent: She congratulates Haiji after being defeated by her.

     Yuuya Nomoto 

Yuuya Nomoto

Voiced by: Wataru Hatano
https://static.tvtropes.org/pmwiki/pub/images/yuya.png

  • 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.
    • He has no intention of getting Hitomi hurt despite his frustration at how she nearly assassinated him and takes risks to protect her during the Deathtival.
  • 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. Subverted later on when it is seen Yuuya is putting on a facade and can't bear to see Hitomi hurt. He's actually more upset that she was forced to kill him than that she did go through with it.
  • Butt-Monkey: Yuuya acts like a tough guy after Hitomi betrayed him and gets his own Brute form, but reconciliates with her at the first opportunity and goes back to being comically abused by her any time she's upset. Even Oshie gets to knock him out. In the spinoff, Inaba hits him with a baseball bat just to tell Hitomi that if she's interested in seeing what his dick looks like she should just undress him right there and then.
  • 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...
  • Gag Penis: Subverted; bird-men in the story don't have their genitals changed upon transforming, but Yuuya either turns or already was a quickshot who comes from Hitomi just poking him with her claw.
  • 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.
  • 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.
  • Undying Loyalty: His devotion to Hitomi is unwavering, forgiving her for trying to kill him and actually more angry that she was ordered to hurt someone she cared about. The narration states that unlike other animals, Crows are monogamous and will mate for life.
  • 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. It's later revealed that was only part of the reason.

The Four Zaibatsu

Ishida

     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
https://static.tvtropes.org/pmwiki/pub/images/ui.png

  • 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.
    • She is the focus of the "Run and Hide, Inaba-san!" omakes from the second arc on and also got her own spinoff called Hoshi Gari Sugidesho!? Inaba-san.
  • 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. That's it for the main story, but her spinoff shows the stress from maintaining her lies about being strong and managing Carrot Field sent her sex drive out of control and led to a fixation on meeting men whose Brute form dicks are unusual, even though beastpeople intercourse is outlawed in the red light district and none of them seem like they fit in her anyway...
  • Bring My Brown Pants: She understandably wets herself when she sees Kido punching his own teammate in half.
  • Catchphrase: In her spinoff she has a nearly episodic "This is turning me on..." monologue.
  • Dark Horse Victory: Literally no one, not even herself, saw her accidentally kicking Eruza in the face and knocking her out, emerging victorious.
  • Early Installment Character-Design Difference: In her early appearances, her teeth were drawn with more detail while transformed.
  • Extreme Libido: The spin off shows she masturbates a ton on her free time, and after having a sexual encounter for the first time she actually rushes back home so she can masturbate even more, complete with narrator funfacts on why rabbits would do that.
  • 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.
  • Hell-Bent for Leather: She's asked to wear a dominatrix costume to service a masochist customer in chapter 3 of her spinoff. This trope has noticeably been an once per series gag with the author, but instead of it happening out of nowhere it's Ui who doesn't quite fit the sadist archetype.
    "What!? What's with this outfit!? Am I a dominatrix!? Or am I a bunny girl!?"
  • Hooker with a Heart of Gold: She's more competent at being a sex worker than at fighting and is one of the more good-natured characters in the story.
  • 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.
  • Mistaken for Badass: 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.
  • Ms. Fanservice: Portrayed as one early on and in her lewd spinoff, though she's mostly seen in a oversized suit from the Deathtival arc on and in the spinoff she doesn't provide so much straightfowarded fanservice after the R-Rated Opening.
  • Nightmare Fetishist: In the Inaba-san spinoff she's often impressed by the genitals of the male Brutes, but one particular scene has fantasizing about getting raped in public by Yuugo when she's tasked with performing a handjob on him during a soapland competition, and climaxing on the spot without doing anything to him. Yuugo declares her the winner of her round just because he had never seen a mistress that happy to work before.
  • Pervert Revenge Mode: In one of the extra chapters, out of pent-up stress, she knocks out a pervert who was groping her but neither she nor the nearby drunk Riku pay attention to what exactly happened.
  • 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.

     Ichinosuke Okajima 

Ichinosuke Okajima/Brute Hippopotamus

Voiced by: Tōru Ōkawa
https://static.tvtropes.org/pmwiki/pub/images/okajima.png

  • 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.
  • Big Eater: He's often shown eating/in a food coma throughout the start of the series.
  • A Day in the Limelight: Ichinosuke is a side character in the first arc and goes out of focus in the second one. In the King of Killing Bites tournament, he's the one competitor under orders to put an end to Yashin's plans and scores wins against both Ena and Eruza. His signature attack, which unsurprisingly is just a massive chomp, even gets the honor of being a Title Drop.
  • Dropped a Bridge on Him: After being in the spotlight for a while in the final arc and beating both Ena and Eruza in tough fights, Ichinosuke is uncerimoniously ambushed and possibly killed by a pack of four raptors before he can even transform to fight Koyomi.
  • Dynamic Entry: He actually has entered the scene tackling an opponent three times, and they never see him coming.
  • Eye Scream: Brute Hyena tears out his left eye during their battle and Cheetah slashes the right one afterwards.
  • 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.
  • Fat and Proud: His main Character Tic is slapping his giant gut.
  • Gentle Giant: Unlike an actual hippo, he's a rather pleasant guy.
  • Handicapped Badass: He loses one of his eyes to Ena and the other to Eruza but still defeats both of them with his sharp sense of hearing and overwhelming power.
  • 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.
  • Huggy, Huggy Hippos: He's a fairly polite and friendly hippo-man. Even as he showcases his true power in the final tournament, he still spares both Ena and Eruza's lives after hitting them with what is supposed to be a lethal bite.
  • I Am Not Left-Handed: While already a fierce opponent, Brute Hippo was holding back in the original Destroyal and forbidden from utilizing his most dangerous attack. When his mistress orders him to win at any cost, he unleashes the titular "Killing Bite" and defeats Hyena by crushing her in his massive jaws. The move was previously banned from competition, viewed not as a fighting move but a means to kill.
  • 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: A Hippo's thick skin is one of its most important traits, and eventually partially transforming allows him to shrug off attacks from the likes of Tiger. The thick skin and layer of fat underneath also prevents a fully transformed Hyena from attacking his vitals.
  • 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.

Voiced by: Yoshino Nanjo

  • Big Good: Probably the closest thing to one in this series, demonstrating concern for the lives of her subordinates and acting to assist Nomoto by providing him with life-saving surgery and a new identity.
  • 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 Nomoto'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.
  • Silk Hiding Steel: Soft-spoken and demure, Seira is still a major player in Killing Bites with an iron will and keen intellect.
  • Yamato Nadeshiko: Prefers to dress in traditional fashion, usually concealing a smile behind a decorative fan. She is every inch the classic Japanese noblewoman, and a talented businesswoman that holds her own for the sake of the Ishida Zaibatsu.

Yatsubishi

     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
https://static.tvtropes.org/pmwiki/pub/images/eruza.png

  • Abusive Parents: The Nakanishi siblings were abandoned by their parents, left in the care of an abusive relative that tried to molest Eruza.
  • 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 and accidental kick to the face.
  • Bring My Brown Pants: Eruza wets herself when caught directly by Lion's Mighty Roar, seemingly paralyzed with fear.
  • Butt-Monkey: Eruza is only ever around to have that smug smile wiped off her face as she's throughly beat up and humiliated in heavily sexualized ways. Even when she wins a fight it's just to lose badly right after. The saving grace is that she's spared from being horribly gored like other girls in the series have been.
  • Designated Girl Fight: Her first major opponent in the Destroyale is Kaede the gecko. In fact, most of her major fights are against women.
  • The Dog Bites Back: One of the defining moments of her life was when Taiga stopped a relative from molesting her, then encouraged Eruza to stand on her own. She proceeded to beat the shit out of her attacker, and never looked back.
  • 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.
  • I Surrender, Suckers: When faced with Lion's Roar, Eruza wets herself and runs away from him with tears in her eyes. However, this seeming moment of weakness is actually a ploy to gain the upperhand and outmanuver Lion — building up speed and bouncing off the arena's fencing to get behind him.
  • Letting Her Hair Down: By the second part of the story, she has stopped wearing pigtails and now it falls to the middle of her back. In the third, she cuts her hair short.
  • 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 Brutes in the series, and outside of battles she behaves like a normal girl.
  • Reused Character Design: She heavily resembles Megumi "Gokiburi" Oki from the author's previous work Arachnid and is introduced creeping on Hitomi with the same school uniform the roach girl wore in that series to drive home the point. Their personalities do differ in that Eruza is more well adjusted than Goki and is mainly portrayed as a doting sister.
  • Smug Snake: She only gets smugger and smugger with each appearance despite getting humiliated in every fight she's in and losing the Destroyale to Ui out of sheer bad luck. After Yuugo acknowledges Eruza's power and concedes defeat to her, this culminates in the cheetah bragging about being stronger than her brother Taiga only to lose very badly to Ichinosuke despite having an overwhelming advantage against him.
  • Sore Loser: She hates how Ui defeated her by accident and enjoys threatening the rabbit whenever she sees her.
  • Spell My Name With An S: Called "Elsa" in some promotional materials.
  • Took a Level in Badass: During the Deathtival, 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
https://static.tvtropes.org/pmwiki/pub/images/taiga_0.png

  • 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.
  • Put on a Bus: Koyomi beats the snot out of Taiga offscreen and he spends the first phase of the King of Killing Bites tournament in a coma. He wakes up on chapter 96, ready to hijack the battles to come. It helps that 2022 is a Year of the 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. He even wakes up from a coma upon hearing Leo had lost the tournament yet again, unaware that it was his sister who sort of beat him.
  • Smug Super: While overconfident, once he gets serious there's a very strong chance you'll end up dead.
  • Steven Ulysses Perhero: "Taiga" sounds like "tiger".
  • 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.
    • Taiga takes Koyomi seriously after finding powerful newcomers in Pure and Ena, and asks her to fight at full power. He still ends up quickly getting knocked into a coma offscreen.
    • During the King of Killing Bites, Leo mocks Taiga to Eruza's face, stating both siblings thought they could easily defeat him when it's more like they can't fight properly at all.
  • 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 views Yuugo as his strongest opponent and gets enraged whenever the man doesn't participate in Killing Bites or gets defeated by anyone else. Yuugo puts on a friendly facade when speaking with Taiga, but views him as a weird stalker and tells Eruza he believes both siblings were always too weak to take on him.
    • 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.

  • 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 too tough to pierce.

Kaori Rikujou/Brute Civet

Voiced by: Yuu Asakawa
https://static.tvtropes.org/pmwiki/pub/images/untitled_183.png

  • 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, and then she's never seen again.
  • 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.
  • 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.

     Yashin Iwasaki 

Yashin Iwasaki

  • Ax-Crazy: He's a cartoonishly psycho villain who wants dinosaur mutants to take over the Earth. And it turns out that, indeed, all the other 7999 people capable of turning into raptors are just as Always Chaotic Evil.
  • Bad Boss: Since the Destival's preliminaries, he alienates Shidoh with actions such as blaming him for Koyomi sending Taiga into a coma and then ordering Koyomi to assassinate Hitomi at a hospital.
  • Badass in a Nice Suit: While Yashin takes on the role of a Non-Action Big Bad for most of the story, it's eventually revealed that he can transform into a bloodthirsty raptor and he keeps his fancy business suit in that form.
  • 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 a evil plan involving the militarization of the Gigant and Saurant categories of Brutes.
  • Bitch in Sheep's Clothing: He pretends to care deeply for his subordinates, telling Eruza that he thinks of her as his own child. But as soon as he turns his back on her, he's gleefully laughing on the inside and thinking about how both siblings are going to become sacrifices for his greatest product.
  • Card-Carrying Villain: Shidoh accuses him of not only being a power-hungry genocidal bastard but also of being a race traitor who believes mammals are below dinosaurs. Yashin just laughs and says his intentions really are that simple.
  • Crocodile Tears: He makes a big show of weeping in front of Eruza, but it's totally fake.
  • 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 across as creepily calm.
  • Eviler than Thou: He makes Shidoh look understanding by comparison.
  • Orcus on His Throne: He spends most of the series as an apparently normal man observing the Brutes fight in tournaments and hoping the ones he favors win for the sake of warmongering business. Eventually, he gets frustrated enough to show Shidoh that yes, he can transform into a dangerous raptor and fight, too.
  • Rule of Cool: In a world where people are turning into all sorts of werebeasts, Yashin specifically wants to militarize kaijus while plotting to make dinosaurs the overlords of the Earth. He refuses to see Pure as anything but a mediocre puppy, even though she's been trained to be an obedient killing machine who can go toe-to-toe against said giants and dinosaurs.
  • Slasher Smile: 99% of the time he appears he is seen sporting a smile that would make demons run.
  • Social Darwinist: Shidoh sought to turn everyone into beastmen as a way to bring equality for mankind. Yashin rejects this, and instead only wants the tiny fraction of the population capable of turning into dinosaurs to survive.
  • Utopia Justifies the Means: Pulls the "overpopulation" and "pressure on natural resources" cards to justify dino-men exterminating all other people in the planet, but the truth is that he just really likes dinosaurs.

Mitsukado

     Youko Mitsukado 

Youko Mitsukado/Youko Mitsui

Voiced by: Megumi Han
https://static.tvtropes.org/pmwiki/pub/images/youko_4.png
  • 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.
  • Fallen Princess: After the Time Skip, the Mitsukado Zaibatsu has been dismantled and she has been living as Leo's mistress. After leaving him, she begs Seira Son for assistance and begins a new life as an ordinary office worker. She's surprised to find she's actually happier living this way.
  • 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'.
  • A Match Made in Stockholm: Youko is portrayed as being traumatized by how Yuugo treated her on the years between the Destroyale and the Deathtival but also feels infatuated with him to some extent, blushing when he asks her to come back to him after saving her from other rapists. Even Yuugo is surprised when she kisses him and ominously says she owes him for making her "strong".
  • Office Lady: After leaving Leo, she takes a job working at Seira Son's bank as one of these. Her coworkers are stunned by her beauty and skill as an office worker. Youko admits that she's actually happy with her new life.
  • 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.
  • 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. It is shown he treated her as a sex slave during the time skip, breaking her spirit until she ran away seeking sanctuary from the Ishida faction. She's able to start anew as a office lady from then on, though she's still threatened with kidnapping and rape just to end up saved by Leo of all people. Youko falls in love with Leo in the most egregious way at this point, with his treatment of her being portrayed as something positive that made her mature from the bratty girl she was.
  • 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".
  • "Take That!" Kiss: During the King of Killing Bites, she kisses Yuugo on the lips and ominously thanks him for making her strong. Given that Yuugo murdered her grandfather, raped her and then treated her terribly for over a year, even he is surprised and confused at what she might be planning.
  • 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.
  • Yamato Nadeshiko: As Youko Mitsui, the new Office Lady working for Son Bank's office. She's beautiful, elegant, and soft-spoken while demonstrating exceptional abilities as an office worker.

  • 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.
  • Hated by All: None of the other Zaibatsu like him, nor his faction as such they have no problem working with Shidoh to kill him.
  • 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

https://static.tvtropes.org/pmwiki/pub/images/yuugo_tani_1_0.jpg
Voiced by: Yuki Ono

  • Characterization Marches On: He rapes Youko before turning her into a sex slave offscreen for two years, which leaves Youko with a broken spirit until she asks for the Ishida faction's help. However, Yuugo's characterization afterwards increasingly contradicts the notion that he would have been cruel enough to harm her so much after the initial rape, which was done out of personal revenge on her and her grandfather. Inaba's spinoff even portrays him comically and shows he derived sexual pleasure from being talked down by Youko.
  • 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.
  • Even Evil Has Standards: Yuugo switches from being a cruel and ruthless killer to being as honourable as Taiga believes he is on a whim, showing consideration for Youko despite previously sexually abusing her for a long time, letting Eruza win against him to let her build confidence or even keeping Koyomi from slaughtering a helpless Yui.
  • 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.
  • Fetishized Abuser: He rapes Youko right in front of her grandfather's corpse and coldly treats her like a sex slave for over a year, but as soon as he saves her from other rapists she swoon-swoons for him and even thanks him for everything later with a kiss to the lips. The story pulls a near 180º turn on how Yuugo is portrayed from then on, and the whole experience is framed as something that helped Youko grow and mature from the haughty, bratty girl she was.
  • First-Name Basis: He's the only one who calls Tiger by his first name.
  • Graceful Loser: He spends much of his match against Eruza dominating and mocking her as weak, but his arrogance causes him to fall for a feint. After Eruza throws off his Roar and gains the upper hand, he acknowledges her as a strong opponent and concedes the match.
  • Heel–Face Turn: In the bestiality spinoff of all things, Yuugo tells Inaba he switched sides to the Ishida faction in secret at some point.
  • 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 Dog:
    • He rapes Youko in the same room as her dead grandfather as an act of Cruel Mercy after she treated him and other fighters like pawns, likely preventing the other conspirators from having her outright killed. Then he needlessly treats Youko like a sex slave so badly for a long time that's she's nearly reduced to an Empty Shell until gaining the will to break free from him.
    • During the King of Killing Bites tournament he easily beats Eruza up and humiliates her on live television, saying her and Taiga are worth nothing and even ripping her clothes as if he was about to rape her right there and then.
  • 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 and Pure of course.
  • Not So Stoic:
    • When Youko kisses Yuugo on the lips and ominously thanks him for "making her strong", he is shocked in a way that implies something else about her has changed other than her becoming bolder or even having some Stockholm Syndrome towards him.
    • Yuugo is called to be the judge of a dispute between two soaplands in the Inaba-san spinoff. His unflappable attitude immediately crumbles as the mistresses service him.
  • Pay Evil unto Evil: 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.
  • Pet the Dog:
    • Despite treating Youko like a sex slave and parading her like a trophy, Yuugo is impressed that she fled from him and turned over a new leaf under Seira Son's care. He asks Youko to come back after saving her from rapist kidnappers, but leaves her be after hearing she plans to participate in the next Killing Bites as a team manager against him.
    • Yuugo harshly beats up Eruza and strips her during their fight to throughly humiliate her, but as soon as she works the courage to land a solid slash on him, he decides to acknowledge defeat to let her build confidence.
    • He of all people is who stops Koyomi from killing Yui when the poor otter was being eviscerated by the dinosaur.
  • 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.
  • Underestimating Badassery:
    • Loses to a newcomer, Hitomi, in the opening fight of the series. However, it turned out he lost easily on purpose to participate in a conspiracy later on.
    • During the King of Killing Bites, Leo mocks Taiga to Eruza's face, stating both siblings thought they could easily defeat him when it's more like they can't fight properly at all. Eruza manages to fight through her urges to flee from Yuugo and lands a slash on him, causing the lion to assume she had been pretending to be weak the whole time and concede to her so she keeps the morale boost.
  • The Worf Effect: While he's a genuinely strong Brute, he's quickly defeated by Hitomi in the very beginning to show her strength. His loses to Hitomi and Eruza are excused as him not taking them seriously and having ulterior motives to let them win. If he bothers, then he performs feats like defeating an Arc Villain like Koyomi while standing in place.
  • 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.

  • 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/Brute Gorilla

https://static.tvtropes.org/pmwiki/pub/images/brute_gorilla.png
Voiced by: Yūsuke 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 trees....in 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.

     Takeshi Kido 

Takeshi Kido/Brute Pangolin

https://static.tvtropes.org/pmwiki/pub/images/takeshikido.jpg
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.
  • 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.
  • Heart Is an Awesome Power: Bet you didn't expect a pangolin to be this fearsome. Neither did any one of his foes.
  • 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.
  • 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.

Sumitomo

     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

https://static.tvtropes.org/pmwiki/pub/images/bild_2018_07_23_15_37_12_555.png
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.
  • Underestimating Badassery: Some time after losing to Haiji, Kaede gives a long-winded explanation to an unseen interviewer about how she lost because she didn't expect the goat to be one fearless, unpredictable, downright satanic badass.
  • Wall Crawl: Thanks to her biology, she can crawl walls and even hang upside down with only her tail.
  • 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 Deathtival. Kaede is reintroduced by killing a boar man effortlessly but is then defeated by Haiji in a well disputed fight.
  • Worthy Opponent: She comes to respect Haiji and Eruza after fighting them, but ironically ends up jinxing both girls with her praises. Haiji easily loses to Pure after defeating Hitomi and Eruza gets chomped by Ichinosuke even though she had just about everything she needed to win.

     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

https://static.tvtropes.org/pmwiki/pub/images/den_oonuma_1_5.jpg
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 gets put back together multiple times but 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. Subverted later on, as he returns with a Heel–Face Turn. Perhaps getting his serpentine manhood ripped out brought the best in him.
  • Half the Man He Used to Be: He is ripped in half by Hitomi but as mentioned below, he survives. Den also gets blown up to pieces while trying to restrain Nodoka and later by Agito but he still 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 "Mister 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. Multiple times.
  • 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.
  • Red Baron: After surviving both the Destroyal and the Destoval despite being torn to shreds in both and yet none worse to wear, he earns himself the moniker "The Immortal Cobra" by all of his fellow Brutes in the community. He really likes it.
  • 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.
  • The Worf Effect: To Jobber extremes. Every time he shows up his constriction technique is thwarted and he gets cut to pieces, first by Hitomi, then Nodoka and then Agito. He still manages to survive every time.

     Akemi Kishimoto 

Akemi Kishimoto/Brute Horned Lizard

https://static.tvtropes.org/pmwiki/pub/images/361893_9.jpg
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.
  • Twincest: The anime heavily implies she has an incestuous relationship with her sister.

     Reiichi Shidoh 

Reiichi Shidoh

Voiced by: Rikiya Koyama
https://static.tvtropes.org/pmwiki/pub/images/shidoh.png

  • 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.
  • Everyone Has Standards: Shidoh is none too happy to have to rely on men who want his transhumanism research for their own greedy purposes. He's infuriated that Yashin wants to use his research for warmongering purposes and is left speechless when the villain proclaims his ultimate plan is eradicating humanity until only a few thousand people remain.
  • Evilutionary Biologist: While he remains ambiguous on the evil part, he believes more hybrids will revolutionize humanity and force them to evolve.
  • Forced to Watch: Shidoh is unable to defy Yashin when Hitomi ends up involved and heavily injured in the fight against Nodoka. He claims to not care if she dies as long as their plan works out, but is clearly seething under his breath.
  • 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.
  • Pet the Dog: Shidoh confesses to Nomoto that sending Hitomi to kill him was a test of character for her, and expresses gratitude for how he's still looking after her in spite of everything.
  • The Stoic: Barely expresses any emotion, save in his flashback with Hitomi.
  • Utopia Justifies the Means: He honestly wants to end wars and discrimination by turning everyone into beastmen, even if it sounds like a nonsensical notion and if he must sacrifice others for it.
  • 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
https://static.tvtropes.org/pmwiki/pub/images/shinozaki.png

  • Asian Fox Spirit: Shidou's deadly, cunning secretary is Brute Fox, with many of the traits associated with the legendary creature.
  • 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.
    • Mai saves Shidou from Yashin after it was thought Rio had killed her.
  • Bizarre Alien Senses: Mai has repeatedly shown that even Stealth Expert Brutes such as the Chameleons and the Snow Leopard cannot escape from her. Foxes have a sixth sense that allows them to detect rodents hiding deep beneath the snow, using magnetic fields to guide them. With this ability, hidden enemies are quickly located and eliminated.
  • Bodyguard Babes: She serves as one for Shidou, when necessary.
  • Combat Commentator: She announces the matches during the Destroyale and the Deathtival, going as far as to kill a group of would-be assassins by herself while interviewing Ui about her being the last woman standing in the Destroyale. For the King of Killing Bites, Mai participates as a combatant and leaves commentary duties to Deshi from Carrot Field.
  • 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.
  • Curb-Stomp Battle: Once she finally manages to challenge Rio in a one-on-one arena battle, she acts as cool as usual— only to get slammed into the ground by Rio's full-transformation elephant trunk, which causes Mai's entrails to start leaking out of her stomach. She doesn't even get a recovery or an opportunity to fight back, because Rio then literally stomps her into a red paste seconds later, meaning the entire hunt to mend her pride was All for Nothing and got her splattered. Averted later on, however, with the reveal that their fight was staged.
  • Dark and Troubled Past: Was left to die by her parents in a snowy mountain when she was just 2 years old, but survived until the Orchard people found her.
  • Don't You Dare Pity Me!: Mai and Rio used to be girlfriends at the hellish Orchard orphanage until Rio, who was an Origin beast in secret, destroyed the entire place overnight and left a beastification vaccine behind to save Mai's life before disappearing. This hurt Mai's pride so much that she got Shidoh from out of the wreckage and started working under him just to eventually find Rio and kick her ass in a fight.
  • Faking the Dead: During a staged fight against Rio, they take advantage of a thick dust cloud to have Mai switch places with a disguised Moe, who is the one who gets stomped on by Rio.
  • Foxy Vixen: Reiichi's sexy secretary is actually Brute Fox.
  • 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.
  • Not Quite Dead: Mai is brutally disemboweled and seemingly stomped flat by Rio, with one of her arms being torn off by the impact. Several chapters later, Mai turns out to be alive and well when she saves Shidoh from Yashin. IT is then revealed the one who got stomped and possibly killed was actually a disguised Moe.
  • 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.
  • Slept Through the Apocalypse: A downplayed example. When Mai and Rio were young, the latter defected from the Orchard orphanage by demolishing the entire place except for the bed her friend was sleeping on. Somehow Mai didn't wake up during the entire incident.
  • The Unreveal: Her Beast Form is teased but not revealed during the Destroyale, with things taking place just off-camera and only a faint glimpse of her clawed hand in the shadows. It's only after the Deathtival that she is revealed to be a fox-woman.
  • The Worf Effect: Chapter 100, the series' Milestone Celebration, is spent on Mai getting gruesomely eviscerated and crushed by her former friend Rio's newly revealed and terrifying Mammoth form without being able to put any resistance once she's yanked out of the air by a giant trunk. It's a pretty sorry sight... until it turns out it was Moe in disguise who willingly let herself be used as a decoy for her.

Other Characters

     Oshie Nodoguro 

Oshie Nodoguro

Voiced by: Sayaka Harada
https://static.tvtropes.org/pmwiki/pub/images/oshie.png
A random girl who is head over heels for Hitomi, but is Not a Therianthrope.
  • Animal Motifs: The usual in-universe logic from the author's works is Played for Laughs. Despite not being a hybrid, Oshie uncannily acts like the Greater Honeyguide, a bird that's used as guide by honey badgers. She unfortunately is unfit to be a brute, but even that comes with a honeyguide funfact. Her Boss Subtitles box goes from calling her a "honeyguide-like girl" in a short crossover with Arachnid to just an "ordinary girl" in the series proper.
  • 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 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, and makes some occasional appearances since then either to cheer Hitomi on or to get mad at Yuuya for becoming close with Hitomi.
  • Yandere: She is very hostile to Yuuya, tricking him into approaching a group of delinquents so he can't "date" Hitomi anymore and even trying to murder him herself when she catches the crow feeding Hitomi at a hospital.

Voiced by: Minami Tanaka
https://static.tvtropes.org/pmwiki/pub/images/pure_6.png

  • 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.
  • Attempted Rape: Almost gets raped by a sleazy frog-man and then Ena later on due to her naiveté, but Pure is the odd one out among the author's female protagonists in that he didn't concoct a way for her to be threatened with rape or anything else as soon as she is introduced.
  • 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.
  • Crazy-Prepared: Knowing her opponent Rio has a giant transformation, Pure brings a trampoline to the rooftop of the school building they're fighting next to so she can use her ultimate move during their fight.
  • 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.
  • David Versus Goliath: Kills the giant sloth Nodoka with Yuuya's help and manages to knock down the giant mammoth Rio on her own.
  • Deadly Lunge: Whether she's giving hugs, chomps or just avoiding attacks, Pure often lunges from out of nowhere at people.
  • Death from Above: She can slice through giant enemies by diving onto them from the sky with the aid of either Yuuya or a trampoline.
  • 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 who was killed in the same accident was used as the surgery's base.
  • Expy: She resembles Alice Fujii from the author's Arachnid and shares a lot of traits and even some scenes with her. They're both kind-hearted and present well but draw power from mental issues to fight and kill (Pure is also way brighter and more selfless than the spider-girl). Both also have a penchant for leaping at enemies to chomp their necks off, but this is effective for Pure and The Worf Barrage for Alice.
  • 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 howl at the moon.
  • 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 third 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. However, this doesn't stop Pure from imagining Tasuku and Nodoka also hanging out with her, and the two are vivid hallucinations who talk about things Pure wouldn't know about. Furthermore, even though the Tasuku delusion is sometimes drawn without certain traits as if Pure is remembering her wrong, Pure starts channeling her to such an extent that Gou actually sees Tasuku standing behind Pure.
  • 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.
  • Power Copying: Domestic canines are by far the most adaptive animals, capable of learning in ways that outshine even Primates. Pure is able to "steal" the moves of her opponents through observation, using the Tasmanian Devil's "Devil Groan" to disable Giant Panda.
  • 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".
  • Sanity Slippage: Pure presents well but frequently hallucinates deceased friends guiding her in combat as a coping mechanism. This develops into Pure imagining even absent people who are still alive being next to her to give advice and praise to her.
  • 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 before being forced to do it anyway.
  • Shoot the Dog: Pure is forced to kill Nodoka after her attempts to be merciful indirectly get Tasuku killed.
  • Shout-Out: Her pet beagle was named Nunuupi, akin to the most famous fictional beagle of all, Snoopy.
  • 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.
  • Spectacular Spinning: Frequently spins and rolls while dodging or attacking, which is accompanied by circular speed lines evokative of the manga Ginga: Nagareboshi Gin. One example is when she fights Haiji and gets hit on purpose to spin into the ceiling, bounce back and bite her throat. After Haiji tries to dive off the building with her, Pure calmly flips her into the ground and knocks her out.
  • Spell My Name With An S:
    • Her name is alternatively spelled as "Pyua". Her teacher also misreads the kanji for her name as "Jun".
    • "Nunuupi" should probably be interpreted as "Noopy" since Snoopy is "Sunuupi" in Japanese writing.
  • Spirit Advisor: She "sees" the ghost of her pet Beagle sometimes, and gets advice during difficult moments. She later adds Tasuku and Nodoka to her tulpa collection, and sometimes talks to more than one of them at once.
  • Stealth Pun: She's a literal underdog.
  • Steven Ulysses Perhero: "Inu" means Dog.
  • 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

https://static.tvtropes.org/pmwiki/pub/images/tasdevil.png

  • The Ace: A talented up-and-comer, Tasuku is hailed for having the potential to be the next Ratel.
  • 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.
  • Death by Irony: She once told Pure that if she ever dies, she'd rather it be a dignified death in battle. She ends up getting senselessly and even randomly cut in half by a rampaging Nodoka in her moment of truth as she's about to defeat Hitomi.
  • Decoy Protagonist: After having a healthy amount of character depth and development in the second arc, she is abruptly 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.
  • Dramatic Irony: She doesn't seem to realize Ui is lying about being powerful, even though she saw some footage of the Destroyale from Shidoh.
  • 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

https://static.tvtropes.org/pmwiki/pub/images/ibex.png
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.
  • Artistic License – 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.
  • Battle Strip: She always removes her skirt and panties before transforming into a furry goat-girl, and in one instance isn't even wearing panties upon doing this.
  • Best Her to Bed Her: She responds to a Love Confession by challenging him to a fight, with her panties as a prize.
  • 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, but never learned her name and neither girl recognizes each other when they fight on the King of Killing Bites.
  • Defeat Equals Friendship: Haiji spends the entirety of her fight with Pure seething about how much she hates her, but instantly calms down after losing. Pure takes the chance to reconcile with Haiji by saying that without her, all the friends she has are inside her head.
  • Defeating the Undefeatable: She's gained a reputation as the talented rookie that brings down seasoned veterans, defeating the likes of Brute Gecko and later Brute Ratel in single combat.
  • 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.
  • Fainting: Just like those popular videos of fainting goats, Haiji is prone to keeling over if confronted with anything romantic in nature.
  • Fauns and Satyrs: Her transformation makes her look like the mythological creature.
  • Girlish Pigtails: She wears long pigtails in her human form, which become horns in her beast form.
  • Going Commando: She takes off her skirt to fight during the Deathtival. Luckily her fur keeps everything covered.
  • Heavy Sleeper: Frequently half-asleep in class even though she sleeps properly and early at night.
  • Hoist by Her Own Petard: Pure lets Haiji headbutt her into the air so she can bounce off the ceiling and go for her jugular. Enraged, Haiji pushes her through the wall of the school building like how she pushed Hitomi off a cliff earlier, but the beagle remains calm, flips her down and slams her onto the floor.
  • Horned Humanoid: Her pigtails transform into an enormous pair of curved horns, which are her primary weapon.
  • Kick the Dog: During the final tournament, Haiji becomes uncharacteristically angry and unloads her frustrations on Pure, the annoying extrovert dog-girl who's been following her all the time. Haiji plays heel for a bit and gets dunked on concrete but is quickly befriended by Pure afterwards.
  • Let's Fight Like Gentlemen: While other Brutes will viciously exploit an opening, Ibex allows her foes to recover before launching another charge. This is a natural trait of the Goat, avoiding the risk of needless deaths when engaging in ritualized combat.
  • 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.
  • Loners Are Freaks: Haiji is a selfish girl who wants to live a solitary life but keeps being followed around by the hyperactive Pure, especially after Tasuku's death. Even though Pure is the only person who regards her as strong from instinct alone, Haiji loathes Pure's extroverted nature and believes their relationship is tainting her motivations. This leads to her outright trying to kill Pure when they fight and having a Villainous Breakdown that ultimately causes her to lose far more easily than anyone had expected.
  • Not So Stoic:
    • Even though she's often lazy and bored with things, the news of having a secret admirer make her fall over in a silly four-legged pose.
    • A young Hitomi once scared Haiji out of her wits by kicking her down a ledge high on a construction site before grabbing her. In their fight, Haiji seems to realize who Hitomi is when she pushes her off a cliff but fails to make her afraid at all.
    • Haiji treats Pure with disdain, saying she hates how "noisy" Pure is and that she'd rather not be followed around by the puppy-girl, but is otherwise calm and civil around her... until they're set against each other at the King of Killing Bites tournament and Haiji uses it as an outlet to take out her frustrations on the girl, loudly ranting about how she hates Pure to the point of wanting to kill her.
  • Not the Fall That Kills You…: Haiji likes to run off very high cliffs while pushing her opponents head-first into the ground, intending to inflict on them the fear she once felt when a young Hitomi kicked her off the top of a construction site. Ironically, she defeats Hitomi this way but fails to make her afraid and feels no satisfaction. Later, she pushes Pure off a school building but gets flipped around and is incapacitated by the impact.
  • Paralyzing Fear of Sexuality: Played for Laughs. Haiji is so inexperienced with romance, that getting a love letter causes her to faint from shock.
  • Satanic Archetype: Downplayed. Despite not being evil whatsoever, she is loosely compared to Satan. For one thing, the goat is seen as the favored animal of the Devil. They prefer climbing high places which are seen as sacred grounds for the holy, so it's as if they are trespassing in God's territory. They also value freedom very much. Also, Haiji's two bad trades are that she is lazy and self-serving, which are vices connected to Satan.
  • Shout-Out Theme Naming: She's named after Heidi, Girl of the Alps.
  • Smug Super: Whenever she encounter an enemy, Haiji runs away... just to see if they can catch up and be worth her time.
  • Steven Ulysses Perhero: Her last name sounds very similar to "Goat".
  • 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.
  • The Worf Effect: Haiji defeats veterans like Kaede and (an injured) Hitomi on top of performing well against Nodoka, which gets her enough of a reputation that Pure believes she has no hope of beating her. Even Hitomi and the tulpas on Pure's head tell the beagle-girl to just give up. However, when the time comes, Pure remains focused and knocks Haiji out in just a chapter by turning her attacks against her.

Team E

     Ena Haibuchi 

Ena Haibuchi/Brute Hyena

https://static.tvtropes.org/pmwiki/pub/images/ena_8.png

  • Bitch in Sheep's Clothing: Her standard trick is to appear cute and harmless, right up until her victim's back is turned.
  • Card-Carrying Villain: By the King of Killing Bites tournament, Ena doesn't even pretend to be nice and looks positively unhinged, with her pseudo-penis hanging from her dress the whole time, as the announcer hypes her depravity.
  • 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.
  • Dark Action Girl: She's an especially strong Rookie, and quickly establishes herself as particularly nasty in a cast of ruthless individuals. By the King of Killing Bites tournament, she's earned a reputation for sexual depravity.
  • 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.
  • Does Not Like Men: True to the matriarchal nature of Hyenas, she views men with inherent suspicion and jealousy.
  • 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.
  • Even the Girls Want Her: She turns out to be quite popular with the ladies, and has a harem of Cat Girls. Then again, regarding the aforementioned harem it's unknown how many of them either came to her of their volition out of genuine attraction or are her broken previous rape victims that she subjugated into effective carnal bondage, considering her depraved proclivities.
  • Extreme Libido: She's utterly sex-obsessed, spending time during both tournaments having sex instead of fighting.
  • 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 violating other women.
  • Full-Frontal Assault: During the King of Killing Bites tournament, she's wearing a skirt short enough to leave her pseudo-penis fully exposed for all to see.
  • 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.
    • Furthermore, this is actually how she ended up becoming a Brute. As a child, she bit and maimed a male daycare worker for getting too close to her "girls".
  • 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.
  • Ojou Ringlets: She styles her hair with a looser variation of drill curls, imitating the sweet and wholesome persona of a "princess"-type Idol. It's all a carefully-crafted front, hiding her twisted and dominateering personality.
  • Oh, Crap!: She's utterly shocked and terrified when she realizes she's stumbled upon Tiger's hunting ground.
  • Personality Powers: During her origin story, the narrator implies that Ena instinctively gained the abilities of hyenas while undergoing the beastification sugery for the advantages they would grant her for dominating other women.
  • Psycho Lesbian: She enjoys having her way with pretty girls, taking advantage of her.....unique Brute biology. It also turns out that her odious qualities date back to her childhood when she created a sexist hierarchy among the children in her daycare to claim the girls as her "harem" (since she knew of her homosexuality at a young age) and maimed a male daycare worker simply because one of her "girls" developed a puppy crush on him.
  • 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.
  • Uncertain Doom: Ichinosuke biting half of Ena's body in his hippo form is hyped up as him turning ruthless enough to kill and the attack even gets the series' title as its name, but once he spits her out, in one piece, it is not made clear if the bite actually killed her until a later fight is described to end with the first death in the tournament (not counting the opening match).
  • Villainous Rescue: 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.

Team V

     Moe Hanzaki 

Moe Hanzaki/Brute Salamander

https://static.tvtropes.org/pmwiki/pub/images/djblvexv4aawoyp.jpg

  • 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 obsessed with getting attention from all kinds of self-harming stunts even as reactions turned into disgust and rejection.
  • Back for the Dead: After being sliced in half by Koyomi, Moe is seen several chapters later being used as a sacrifice to fake Mai's death. It is implied that being crushed by the giant Rio might have killed the psycho salamander for real...
  • 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.
  • Death by Irony: Even though Moe is described as being a suicidal Attention Whore, she seemingly dies while disguised as Mai and out of all her acquaintances only Pure knows about it.
  • Dying as Yourself: Moe is crushed while disguised as Mai to help fake her death, but is symbolically framed as her real and twistedly happy self in what seems to be her final moments before the giant paw smashes her.
  • 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: While Eruza resembles Gokiburi from Arachnid, Moe takes more personality traits from her such as her masochism and a obsession with being hated.
  • Face Death with Dignity: When tasked with being crushed by Rio while disguised as Mai, Moe is for a moment scared that she might die for good this time but braces herself and takes the hit with pleasure.
  • 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 in the Deathval when she gets clawed in half by Nodoka, but even then she still doesn't seem bothered at all and gets put together later.
    • Koyomi likewise slashes Moe in half just so she can challenge Pure right there and then without distractions. A gratuitous Panty Shot makes it apparent that she climaxed on the spot.
  • Healing Factor: She regenerates almost instantly, and really enjoys the process.
  • Heroic Sacrifice: She eagerly lets herself be used as a decoy for Mai when they need to fake the fox-woman's death. It's unclear if that did kill Moe for good.
  • 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 can be friendly 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.
  • 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.
  • Shoo Out the Clowns: Moe is mostly around for eroguro purposes and to look goofy as she gets aroused from being beaten and dismembered, until she's chopped in half by a arc villain and can't take part in the action anymore. In the final arc, she's seemingly killed in a dramatic way by being crushed by Rio while in disguise to fake Mai's death.
  • Squashed Flat: During the battle against Nodoka, Moe points she doesn't know if she could survive being crushed by the giant. We later learn it was her who got stomped on by Rio while disguised as Mai, and she eagerly accepted being sacrificed even if it meant it could kill her for good.
  • 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.
  • Uncertain Doom: She is crushed by Rio in a plan to to fake Mai's death, with the scene framed as if she's fully prepared to die while declaring her name and obsession with masochism as her last words. Whether or not her Healing Factor can save her from even that is unclear.

     Gou Arimori 

Gou Arimori/Brute Anteater

  • Bait-and-Switch Boss: He has a bone to pick with Pure after the Deathtival and the King of Killing Bites tournament immediately pits them against each other. Unfortunately, Gou gets hijacked by a giant panda before he can do anything.
  • 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.
  • But Not Too Foreign: He's a Black man with a Western personal name and a Japanese surname, indicating possible mixed ancestry.
  • Covert Pervert: He doesn't seem like the type, but his flowery love letter to Haiji is actually about her panties. The narrator points to an incident of an escaped Kangaroo stealing women's panties for some unknown purpose.
  • 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.
    • The narration references a 2011 incident in which a Kangaroo went on a panty-stealing spree.
  • Stalker with a Crush: Played for Laughs, with Pure accusing him of being a stalker when he leaves Haiji a love letter.
  • Token Minority: The first black character of note in the series.

Other Characters

     Nodoka Uzaki 

Nodoka Uzaki/Brute Sloth/Gigant Megatherium

https://static.tvtropes.org/pmwiki/pub/images/sloth_8.png
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.
  • Disproportionate Retribution: Pure has other friends? She must die!
  • Drop Dead Gorgeous: After being horribly gored by Pure, Nodoka is left naked on the ground with her guts spilling out. It is portrayed as a truly pitiful and underserved fate for her, and upon dying she reverts to her original form of a sloth. Notable in that it starts a trend of the series resorting to sexualized violence to show uncensored female nudity after the Bait-and-Switch with Ryoko flashing Yuuya.
  • 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.
  • Spirit Advisor: Like with Tasuku, Pure keeps hallucinating Nodoka as a coping mechanism to her death, and she talks about things like her upbringing as a lab experiment and how it was like to fight Haiji as if she's the real deal.
  • 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

  • Born Winner: It's casually revealed at one point that he's a natural-born Origin beast, but it is so far unknown if he can transform beyond his wolf form.
  • Cool Old Guy: Riku is the eldest known Brute in the series, and well-respected as a veteran competitor that has survived into his golden years. He often takes advantage of his age to fool his opponents, letting them mistake his advanced age as weakness.
  • Glass Cannon: His age means he cannot fight for prolonged periods of time, but he's just as powerful as any other Brute.
  • The Man Behind the Man: Ui is the celebrity in charge of Carrot Fields, but Riku is the actual brains of the operation and recruited her solely for her fame.
  • Obfuscating Disability: He takes full advantage of his advanced age, letting others mistake him for a weak opponent. Pure's sense of smell is fooled, causing her to underestimate him and worry about hurting an elderly man.
  • Smoking Is Cool: Introduced smoking a cigarette.
  • Steven Ulysses Perhero: "Oogami" sounds an awful lot like "Okami", meaning Wolf.
  • 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.
  • Rhino Rampage: His signature move, charging headfirst at his opponent.
  • Steven Ulysses Perhero: "Sai" means rhino.
  • Threshold Guardians: Serves as one for Carrot Field, as due to how cruel and unforgiving the nature of Killing Bites are, he considers himself the bare minimum for any opponents to surpass before they are allowed to participate in the games for real, turning away any greenhorns or rookies that fail to do so in the process.

     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.
  • Model Scam: 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.
  • 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...)

     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 Dialogue: 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.
  • Giant Foot of Stomping: The way he tries to trample over his opponents is compared to the Firebombing of Tokyo.
  • Ground Pound: Like a real Giraffe, his primary method of attack is to trample his smaller opponents.
  • Hoist by His Own Petard: Igawa uses his neck to slam Koyomi against the side of a building, but she punishes the body blow with a delayed slash to the throat that incapacitates him.
  • Know When to Fold Them: When Ratel threatens to get involved in his match against Tasuku and Pure, 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.
  • No-Sell: When Yugo roars at Eruza during their fight in the King of Killing Bites, most Brutes in the vicinity feel demoralized and even Koyomi cowers in fear but Igawa doesn't care and stays around for his fight against her.
  • 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.
  • The Worf Effect: Gets the dubious honor of being Koyomi's first on-panel opponent and is defeated in a single chapter despite briefly knocking her out.

     Deshi Murata 

Deshi Murata

The enthusiastic announcer at Carrot Field.
  • Bit Character: Only appears to hype the battles at Carrot Field and then the King of Killing Bites, and isn't confirmed to be a member of JTK 48.
  • Cat Girl: A bobtail cat girl.
  • Combat Commentator: Announces the fights at Carrot Field and is hired for that role at the King of Killing Bites due to the usual announcer Mai participating in the tournament as a fighter.
  • Punny Name: "Deshi" means "apprentice" and Murata is the manga's author, so she was likely designed by one of his assistants.
  • Shoo Out the Clowns: When Yashin's genocidal dinosaur supremacy plan begins, the goofy announcer Deshi is among the first civilians who get jumped by the raptors, though she's not explicitly shown being killed.
  • Uncertain Doom: When the raptor apocalypse kicks off, one dino-man jumps next to Deshi and she freezes in fear as she realizes it's not a hologram. Then it cuts to Deshi's mic getting knocked away, with her fate being left unknown as the chapter ends on a cliffhanger of Inaba also being attacked.

     Rina Satou 

Rina Satou/Brute Siberian

https://static.tvtropes.org/pmwiki/pub/images/rina_8.png

  • 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

https://static.tvtropes.org/pmwiki/pub/images/jtk.png

  • 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.

Characters in Part 3

     Koyomi Uzaki 

Koyomi Uzaki/Saurant Deinonychus

https://static.tvtropes.org/pmwiki/pub/images/1_690.jpg

The third and youngest Uzaki sister. She is considered the most advanced of the three projects, and conceals a murderous personality beneath her cute exterior.


  • Absurdly Sharp Blade: "Deinonychus" translates from Greek to "Terrible Claw", and so her claws are compared to sickles that can chop people up like they're made of butter. She even slices Yui's fully transformed left arm while underwater.
  • Arc Villain: Built up as Nodoka's successor in the King of Killing Bites tournament, and of course she tries to fight Pure way before they could both make it to the finals.
  • 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 in her dinosaur form. While Hitomi and Tasuku wouldn't be afraid of Koyomi, the more empathetic Pure is frozen on her tracks, completely confused and disturbed by just how unhinged the deinonychus screaming at her is.
  • Badass Back: In Koyomi's introduction she counters Taiga's backstab skill and drives him to a coma. Yui later tries sneaking up on Koyomi to choke her like she did to Agito, but Koyomi handily leaps behind her.
  • Big Eater: Pure befriends Koyomi by offering her ice cream, and then Koyomi makes a surprisingly large order at a fast food restaurant while the two are hanging out.
  • Bizarre Sexual Dimorphism: Surprisingly for a cute character, Koyomi can fully transform into a creepy yet frilly dinosaur.
  • Blood Knight: Pure realizes that Koyomi's hunger correlates to her bloodlust. Koyomi tells Yashin she knew to be cautious around Pure and could barely contain herself.
  • Combat Pragmatist:
    • Due to being beaten up badly by Yuugo after she defeated Yui, Koyomi gets rid of Ichinosuke by siccing four raptors on him before he can even transform. She looks very disheartened as she does it, even if it's because she won't get to personally eat him.
    • She also tries to dispose of Pure this way under Yashin's orders, while looking even more heartbroken. Mutsujirou foils this by taming her raptor minions, allowing his "daughter" to prove herself against Pure in a fair fight.
  • Curb-Stomp Battle: The first impression given of Koyomi is her beating the shit out of Taiga offscreen, leaving him mummified in bandages. Igawa doesn't last a chapter against Koyomi either, and Moe is then cut in half just for being there before the raptor-girl sets her sights on a terrified Pure. She also overwhelms Yui and subjects her to a Humiliation Conga, but only to suffer an also one-sided beatdown from Yuugo minutes later.
  • Death Glare: When she's about to fight Pure, Koyomi stands over her with an almost comical wide-eyed look of derangement on her face for what seems like an eternity until Pure works up the nerve to avoid getting beheaded by her.
  • Dinosaurs Are Dragons: Her Deinonychus form is talked about like it is a dragon instead of a dinosaur.
  • Enfant Terrible: She is said to have been stolen from her parents by researchers on birth and immediately turned into a very agressive dino-girl that chomped two fingers off the caretaker who gave all the "Uzaki" children that surname. Being raised as a killing machine by Shidoh's staff and Yashin doesn't help at all, but Pure still believes she's a good girl deep down.
  • Expy: Koyomi's general character, her being introduced by Yashin while he's arguing with Taiga and the way she steals a kiss from Pure are throwbacks to Dinoponera from Arachnid, most likely for a Stealth Pun regarding Koyomi's animal form. Appareance-wise, Koyomi resembles Kabutomushi from the same series.
  • Face of an Angel, Mind of a Demon: Koyomi looks every bit the innocent girl, with curls in her hair and cute dresses. But she occasionally offers glimpses of something terrifying and powerful, as the "perfect" Uzaki sister.
  • Friendly Enemy: She becomes fond of Pure during their first meeting, but can't wait to fight her to death anyway.
  • Horror Hunger: It's hinted that her appetite goes beyond simply loving to eat, and into something much darker she can't fully control. After their meeting, Pure is shaken by how Koyomi smelled of "Hunger", while Koyomi herself admits later that she could barely hold herself back and that she indeed wants to devour Pure.
  • Kick the Dog:
    • Koyomi might act friendly to Pure, but she suddenly tries beheading the dog-girl upon getting hungry and would've killed her if Hitomi hadn't intervened. Pure still claims Koyomi is a good girl somehow despite her obvious murderous intent towards the beagle-girl.
    • Koyomi starts slaughtering Yui even when the otter-girl has surrendered to her, and the tournament's staff seems to let it happen just to show the terrifying strength of the dinosaur beastmen.
    • On Yashin's orders, she cheats her way out of having to fight Ichinosuke by ambushing him with four other dinosaurs. She only looked sad because she wanted to eat him personally.
  • 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. It turns out her animal form is the decidedly unfriendly-looking Deinonychus, but her cute dress and hairstyle remain on after the transformation.
  • Know When to Fold 'Em:
    • Koyomi gets Pure incapacitated from fear, but after Hitomi starts parrying her slashes she just untransforms with an embarrassed look on her face and leaves. She compares fighting them to ordering both steak and a hamburger at once, in a way that implies she's more concerned over fully losing herself to her bloodlust than the possibility of being defeated.
    • Similarly, she quietly runs off after Taiga interrupts the fight between her and Yuugo even though the men are ambushed by a group of dinosaur minions right afterwards.
  • Made of Iron: Takes a major beating from Yuugo, but stands back up all bloody like it doesn't hurt and actually starts turning the tables on him.
  • Mighty Roar: Even though Koyomi was scared of Yuugo's roar while Pure was not, once she transforms and starts screaming at Pure's face the poor beagle is put on full Deer in the Headlights mode despite her instincts in the form of Tasuku telling her it's not such a big deal.
  • No Sense of Personal Space: Gives Pure an uninvited kiss on the lips at one point, as a way to express how much she wants to beat and eat her up.
  • Raptor Attack: Averted Trope. Koyomi is a human-sized and feathered dinosaur, but accurately identified as a Deinonychus as opposed to the inaccurate-but-popular Velociraptor.
  • The Reveal: It's only several chapters after Koyomi clobbers Taiga offscreen that her animal form gets a dramatic reveal. Her Boss Subtitles box also classifies her as a "Saurant" instead of a "Brute", implying dinosaur fighters will be the next big thing in the setting.
  • 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.
  • Spam Attack: She can float in midair while delivering a barrage of slashing kicks.
  • Thousand-Yard Stare: The cover for Volume 22 is of Koyomi eating fried chicken with a very vacant gaze and her beast form projected behind her as indication of how feral she is under her cutesy appearance.
  • Unskilled, but Strong: Koyomi is quite brutal and psychotic in combat, with it being noted that as a little girl she does everything on instinct. She only starts having a bad time when faced with some attack those instincts have no answer to.
  • The Worf Effect: As the Arc Villain of the final arc, Koyomi subjects multiple fighters to one-sided beatdowns and gets Pure shaking in her boots. On the other hand, Hitomi isn't afraid of Koyomi at all and Yuugo beats the stuffing out of her while barely moving.

     Agito Shiina 

Agito Shiina/Brute Alligator/Gigant Deinosuchus

https://static.tvtropes.org/pmwiki/pub/images/erpggmbxkaa6j_f.jpg

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


  • Abusive Parents: Neglected by his mother, and physically abused by his criminal father.
  • Attack of the 50-Foot Whatever: Like Nodoka, he is able to transform into prehistoric megafauna the size of a building — a Deinosuchus in his case.
  • Beware the Nice Ones: He appears kind and very polite to Pure until he gives her a threatening handshake with a grinning Kubrick Stare, declaring he's going to kick her ass at the King of Killing Bites.
  • Big Damn Heroes: Shows up to support Yuugo and Taiga against the Dinomen in chapter 117.
  • Break the Haughty: Agito is outwitted and knocked out by Yui despite his overwhelming Gigant transformation, so after waking up he just sits by the lake looking depressed while, to add insult to injury, Den comes over to make fun of him.
  • Did Not See That Coming: He sure didn't expect that Brute Otter would be ruthless enough to attack his tongue when he tried to swallow her. And despite their massive difference in size, she actually does turn strong enough in her full transformation to choke him into submission.
  • Dude Looks Like a Lady: Very feminine-looking.
  • Enfant Terrible: Ryuuji came home to discover that Agito had stabbed their father to death with a kitchen knife, and was laughing about it.
  • Face of an Angel, Mind of a Demon: Agito is a very attractive, feminine-looking teenager with a history of extreme violence and cruelty.
  • Genius Bruiser: Agito's Brute form is pure muscle, physically imposing and powerful. But he is also a brilliant strategist, able to predict his opponent's actions and lay down traps to capture them.
  • I Am Not Left-Handed: He initially lets Cobra think he has the upper hand, before revealing his secondary transformation.
  • Never Smile at a Crocodile: Brute Alligator, a physically imposing and patient, deadly strategist.
  • Prehistoric Monster: A Deinosuchus is a huge, prehistoric crocodilian that could hunt dinosaurs.
  • Reptiles Are Abhorrent: Like the other reptilian Brutes, Agito is a dangerous and cruel opponent.
  • Self-Made Orphan: He killed his father as a child, stabbing him to death.
  • Spectacular Spinning: He attempts to drown Yui by deathrolling her underwater, but she manages to break free and gets behind his neck again, choking him with her empowered arms until he passes out.

     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.
  • Steven Ulysses Perhero: "Same" means shark.
  • Threatening Shark: Transforms into a great white shark.
  • Younger Than They Look: He's a tall muscular man with Hot-Blooded 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. Similarly, he's maimed to establish Brute Otter as a dangerous opponent in aquatic battles.

     Tomo Arimori 

Tomo Arimori/Brute Tamandua

  • Cuteness Proximity: Her only real power. Like a real tamandua, she tries to intimidate her foes by spreading her arms to the sides, but it just looks like an invitation to a hug.
  • 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.

     Rio Sahara 

Rio Sahara/Brute Elephant

https://static.tvtropes.org/pmwiki/pub/images/rio_1.png

  • Amazonian Beauty: A beautiful, powerfully-built woman that stuns the crowd when introduced, both for her size and her.... generous attributes.
  • Ambiguously Brown: Her skin-tone is slightly darker than other characters.
  • Bizarre Sexual Dimorphism: Only her arms and the top half of her head transform. Eventually revealed to be only her semi-transformation, as she turns more elephant when fully transforming.
  • Boob-Based Gag: She's a very tall and busty woman who turns into a large elephant. A Running Gag is people calling her huge for her breasts first and foremost, all while the camera zooms point-blank at them.
  • Born Winner: Like Hitomi, Rio is an Origin Beast that has possessed her powers since birth. This power gave her a natural edge throughout her life, allowing her to survive against all odds.
  • Buxom Beauty Standard: Her introduction scene involves the folks at Carrot Field repeatedly thinking how she's "HUGE!", while a panel focuses on her chest. Later on, it serves as Brute Rhino's final thought when facing an even bigger pair, before getting crushed by them in a fight through a body-slam. Her Mammoth form boosts her breasts even further and finally rips her clothes off, leaving them exposed to all the onlookers.
  • Cool Helmet: Only transforming half of her head gives this impression. It turns into a complete elephant's head when she fully transforms.
  • Curb-Stomp Battle: After all the build-up to Mai hunting her down so they can resolve their rivalry, Rio goes into full-transformation, slams Mai with an elephant trunk so hard that it disembowels her, and then she subsequently does a literal stomp, pasting Mai into the floor and ripping an arm off the fox woman in the process. At the time of chapter 100's release, it's portrayed as outright fatal.
  • A Day in the Limelight: Starting with volume 22, the mini chapters about how Carrot Field was established change from Inaba's perspective to Rio's and are titled "Too huge! Rio-san".
  • Giant Foot of Stomping: Naturally has very large paws while fully transformed, and as a mammoth she quickly kills Mai with a stomp.
  • Graceful Loser: Admits defeat to Pure after becoming too guiltridden over what she's been doing to keep fighting.
  • Marshmallow Hell: She essentially defeats Brute Rhino this way, crushing him beneath her huge... ah... mass.
  • Ms. Fanservice: She's a beautiful and curvy lady often seen in a tattered shirt. Chapter 115 has a couple splash pages showing off her butt and her uncensored exposed breasts, when it's actually a rarity for the series to have explicit nudity without it involving sexualized violence and gore.
  • Mysterious Backer: Ui notes that Rio showed up out of nowhere, and started helping her with no apparent reason. She's been too intimidated to ask Rio, leaving her uncertain about why she's being protected.
  • Mysterious Past: Rio was discovered as a small child, stowing away on a ship from Africa. Nothing of her past prior to being discovered is known, even to the powerful organizations behind Killing Bites.
  • No-Nonsense Nemesis: Despite her calm and polite appearance, Rio is quite the psycho who doesn't hesitate to stomp even a friend to paste in a serious fight. She has this to say about Pure, while patting her shoulder and flashing Black Eyes of Crazy:
    "I never thought I'd meet someone, whom despite knowing my true form, welcomes me into battle with a smile. Inui Pure, I'll never forget about you."
  • One-Winged Angel: Can transform into a Mammoth far larger than even Nodoka's Megatherium form.
  • Punch-Clock Villain: She's blindly commited to following Yashin's orders on the whole War for Fun and Profit thing to have a sense of purpose, and ends up killing her former best friend Mai over that.
  • Unreliable Narrator: All of Rio's regretful internal monologues point to her having killed Mai for real, but then it is revealed they and Pure had plotted to use Moe as a decoy all along.
  • Villainous BSoD: While Pure is unable to knock out or kill Rio even with her best technique, she resists the giant until she has a nervous breakdown over how she killed Mai and gives up.
  • We Used to Be Friends: She has a rather complicated relationship with Mai, stemming from their childhood together. They grew up together at a facility raising potential Beastmen, and eventually became lovers. Rio destroyed the facility and tried to wipe out everyone there to protect Mai. Her efforts were wasted, and instead Mai has spent all these years working for the very same people and hunting for Rio.
  • With Great Power Comes Great Insanity: Averted; unlike Nodoka and previous giant characters, the story emphasizes how Rio is fully conscious even as a mammoth by portraying her in human form in most of her reaction shots and inner monologues.

     Ginzo Watari 

Ginzo Watari/Brute Penguin

  • Bullying a Dragon: He's sure he can defeat Pure because he heard a dog got knocked out by a penguin on a whaling ship once.
  • Joke Character: Turns into a giant penguin with normal human legs, but Pure just knocks him over. Still in sports commentator mode, as if parodying the series itself, Ginzo realizes all his abilities are useless on land and gives up.

     Sylvester Hyodo 

Sylvester Hyodo/Brute Snow Leopard

  • Gratuitous English: Wears a championship belt marked with the word "CAMPION".
  • Look Both Ways: He was hit by a truck as a child and had to undergo beastification surgery to survive. The accident was not any fault of his though, as he did see the truck first before crossing the road, but it's driver utterly failed to see him instead.
  • Perception Filter: He grew up troubled about most people, including his family, being supernaturally ignorant of his existence. Still doesn't keep Mai from beating him up thanks to her fox-like instincts.
  • Production Throwback: Worth noting is that his backstory is recycled from Caterpillar by the same author, where a stickbug-themed girl was somehow unnoticed by everyone around her even after having a nervous breakdown and killing her own mother.
  • Stealth Expert: His introduction hypes him as one of these, much like his rarely-seen species.
  • Suspiciously Similar Substitute: For the comatose Taiga, and even mentions snow leopards are much like tigers.
  • Unperson: One day, he simply came to the realization that not a single person in his life ever had acknowledged his existence at all, neither his classmates, teachers or even his parents seemed to even know he existed in the first place, despite being in their vicinity every day. Something that played a big part in why his brute became the Snow Leopard.

Yui Okawa/Brute Otter

https://static.tvtropes.org/pmwiki/pub/images/otter_5.png

A popular youtuber who signs up for the King of Killing Bites tournament to devour her opponents and is particularly interested in Agito the Alligator.


  • Big Eater: After suffering from a weak gastrointestinal tract from an early age, the beastification surgery not only fixed that but left her with an enormous appetite for the flesh of exotic animals.
  • Big Guy Rodeo: Like a real Otter, she's able to overcome Alligator's size and deadly jaws by climbing on his back and getting him in a choke-hold. This renders him vulnerable to attack, and forces him to transform further to escape an otherwise fatal move... which is followed by her also powering up and eventually sneaking behind him again, at which point he's toast.
  • Bitch in Sheep's Clothing: Yui tries to lull Koyomi into a false sense of security before trying to slash her from behind, leaving readers to ponder if this is at odds with how she behaved in the fight against Agito or if she was just faking her Ambiguous Innocence in front of her audience from the beginning.
  • Bring My Brown Pants:
    • Inverted; when Yui first chomps Agito she finds him delicious and says she's so happy she's "leaking" a bit. After he turns to a Deinosuchus to intimidate her, she's driven to tears and wets herself because she can't believe how good and huge a meal he looks like.
    • Played straight when an unhinged Koyomi has Yui cornered and incapacitated after slashing her arm. The poor otter suffers from incontinence out of actual fear, being even more helpless than Pure was in the same situation.
  • Combat Pragmatist: She fights fairly against Agito the giant alligator but feels the need to cheat against Koyomi, an oversized "chicken". She acts nice to Koyomi, begs for her mercy since "an otter could never defeat a dinosaur" and pretends they'll fix their match in the raptor-girl's favor with a simple fake knockout. Then Yui, in spite of promising to not hurt Koyomi badly as well, tries to slash the girl to death from behind before she can transform.
  • Cute But Psycho: Yui's introduction hypes her "cute" factor, and she's a playful opponent treating everything as a fun game. But she's also an extreme carnivore that joined the tournament for the chance to eat her opponents. As a giant otter, however, she turns ugly and has a permanent Slasher Smile which gives her a more Ax-Crazy look.
  • David Versus Goliath: She manages to beat a giant alligator but is nearly killed by a dinosaur about as big as herself.
  • The Ditz: She's fairly powerful but keeps being goofy and getting distracted while a giant alligator-man is trying to kill her.
  • Eaten Alive:
    • Ironically enough, Agito bites at Yui and almost swallows her whole body. As it happens, she just starts eating his tongue until she can break free, which he finds nasty.
    • Koyomi bites at Yui's abdomen and starts ripping her guts off until Yuugo shows up out of nowhere demanding she stops. Even the deranged audience of the tournament, who have a hologram of the situation right before them, become disturbed by Koyomi's cruelty and how terrified Yui is.
  • Evil Makes You Ugly: She looks cute in her otter form but becomes monstrous and psychotic in her giant otter upgrade, as if to convey she's a kind of a bitch despite looking innocent.
  • Expy: She's found playing in water and is a cheerful and smug Cute But Psycho fighter who runs circles around her opponents, all while doing an Evil Laugh when attacking them. So like Koyomi she comes off as quite Dinoponera-esque while also being her own distinct character.
  • Foil: Yui, a social media personality who only looks like a teen, is set to fight Koyomi, a shy schoolgirl. Both have a very dangerous side and want to devour their opponents.
  • Humiliation Conga: There's a rather jarring sequence of bitchy actions from Yui in how she attempts to fight Koyomi before she loses an arm and gets beaten and eviscerated while crying in horror in a way that's just pitiful. Yui is then tossed down a slope like garbage once Yuugo arrives to challenge Koyomi, but she can't help but be relieved as she bounces into a lake and remains alive and conscious to watch their fight.
  • I Want My Mommy!: Yui is reduced to screaming for her mom when Koyomi starts devouring her, which heavily disturbs even the tournament's audience that was begging for Yuugo to rape Eruza just hours before.
  • Kick the Dog: Yui suddenly starts acting like a conniving bitch against Koyomi, evil Game Face and all, even though her previous fight with Agito characterized her as a hard-working ditz who fights fairly, as if the narrative just wants to make her look bad even though Koyomi is the Arc Villain. Unlike before it is also emphasized how she's trying to kill Koyomi, though it's at least understandable given the nature of the tournament and how dangerous Koyomi is.
  • Killer Rabbit: She has a young appearance and looks innocent, but is a strong enough Brute to earn a place in the tournament. Her formal introduction sees her attack and seriously wound Brute Jaws in an aquatic battle.
  • Literal Disarming: Yui tries to choke and drown Koyomi while they're both underwater but her arm is easily sliced off, which completely incapacitates Yui as she relies on choking for finishing opponents. She starts freaking out and hurries over to her bag to at least bandage the wound but Koyomi stomps on it. Poor Yui would actually rather lose all her other limbs than to get outright killed, but Koyomi rips her belly open anyway.
  • Monstrous Cannibalism: She seems mostly interested in trying to ''eat' her opponents, maiming Brute Jaws and sampling his fin. She's delighted to see her next opponent is Alligator, calling him a delicacy. Ironically, her fights involve Agito almost swallowing her whole and Koyomi starting to devour her entrails.
  • Muscles Are Meaningful: She becomes very muscular in her fully transformed form and is able to choke Agito's giant form until he passes out.
  • No, I Am Behind You: She gets behind Agito twice to put him in a choke-hold and with some effort manages to take down his Deinosuchus form.
  • No-Nonsense Nemesis: Yui kept goofing around while fighting Agito but acts the opposite against Koyomi, repeatedly trying and failing to take initiative to lower the dino-girl's guard while fully intending to kill her.
  • Oh, Crap!: Every time Agito appears to scare Yui it turns out she's just fine, but she's genuinely terrified when Koyomi slashes her arm off and corners her. Until the unlikely rescue by Yuugo, the scene amounts to a drawn out execution as Koyomi literally beats the piss out of Yui and starts eating at her guts while the otter-girl can only scream in pain.
  • Older Than She Looks: She's actually 24 but is short and looks childish due to health issues that stunted her growth.
  • One-Winged Angel: Her full and not so cutesy transformation takes on the traits of giant otters.
  • Playful Otter: But "playful" in the way most Brutes are. Yui is cheerful and energetic, and seems to take the whole thing as a fun game. But she's also quite brutal in a fight.
  • School Swimsuit: She wears one in the tournament, and is noted in her introduction to be a schoolgirl. It makes sense in this case, since she's a Brute specializing in fighting in the water.
  • Screaming Warrior: She loudly shouts "Awawawawa" while fighting, as otters are known to do.
  • Screw This, I'm Outta Here: Yui panics and futilely tries running away for first aid when Koyomi slices her arm off. While this is an understandable reaction to such an injury, it is likely meant to paint the otter-girl as frail and cowardly in comparison to all the other characters like Hitomi or Ichinosuke who powered through limb or eye loss or flat out ignored such damage. Koyomi then starts brutally eating her guts and nobody in the tournament's staff does anything to stop it even though Yui has surrendered and should've been disqualified just from running away.
  • "Silly Me" Gesture: Often makes a silly pose with her tongue sticking out. It's even the illustration for the 19th volume.
  • Speed Blitz: In the water, she's a deadly foe capable of attacking in explosive bursts that overwhelm larger foes such as a Brute Jaws and Alligator. It doubles as a way for her to tear out chunks of flesh, sampling her prey as she wears them down seemingly from all directions.
  • Uncertain Doom: Yui was left terribly wounded with a missing arm and her belly torn open when Koyomi tossed her away. She's seen still conscious in one scene, but it's not known if she made it to safety before the other raptors started showing up and killing everyone.
  • The Worf Barrage: While powered up, Yui choked a fully transformed and giant Agito until he passed out. Unfortunately, when she tries doing the same to a half-transformed Koyomi while they're both underwater, which should be the perfect situation for her, she just ends up losing her left arm.
  • Wrestler in All of Us: Yui likes putting opponents in choke holds and tries grappling with Koyomi before the raptor just flies and drops her on a lake. She trained on a wrestling gym owned by Sylvester, the Brute Snow Leopard.
    "Don't underestimate a YOUTUBER!"

     Brute Giant Panda 

Wang Aizhen/Brute Giant Panda

https://static.tvtropes.org/pmwiki/pub/images/45_9.jpg

  • Acrofatic: Like a real Panda, her stocky and fluffy appearance belies the fact she's a bear.
  • Advertised Extra: She's a minor opponent who shows up out of the blue to fight Pure and is only briefly seen in human form, and yet she is the cover girl for volume 16.
  • Ass Kicks You: One of her signature moves is to butt-slam her opponent, using her large body.
  • Badass Adorable: Intentionally weaponizes this trope, combining her cute appearance with the devastating power of a panda that knows kung fu. Ultimately subverted, when Pure points out that her lack of experience fighting other Brutes is a liability.
  • Bears Are Bad News: Pandas have an adorable, childlike appearance that causes people to lower their guard, forgetting that these are enormous and powerful bears that can easily kill with a swipe of their massive paws.
  • Bizarre Sexual Dimorphism: First appears fully transformed, looking like a normal but oversized panda. It being a woman is played as a twist.
  • Naked People Are Funny: After being defeated and transforming back, she has a Delayed Reaction to being naked that mirrors Pure's from when Tasuku saved her from Brute Frog. Then she gets so stressed out looking for her clothes that she passes out from blood loss.
  • Phrase Catcher: Hilariously steals Hitomi's "that's what Killing Bites is" catch phrase by saying Popularity Power is what's most important.
  • Popularity Power: Giant Panda weaponizes her cuteness to appeal to the audience, and distract her opponents into lowering their guard.
  • Samus Is a Girl: Surprises everyone by being a cute girl. A naked one.
  • Shout-Out: She's a Kung Fu master that is also a Panda.
  • Spoiler Cover: Her appearance on one of the manga volume covers gives away her identity twist.

     Emilyan Hjornov 

Emilyan Hjornov/Gigant Moose

An MMA Openweight world Champion, hoping to break into Killing Bites.


     Dinomen (Spoilers) 
Eight thousand people who are capable of transforming into raptors and serve Yashin.
  • All Animals Are Dogs: Mutsujirou nonsensically demonstrates they can be pacified by petting.
  • Attack of the Killer Whatever: You've heard of the Rape Zombie Apocalypse, now get ready for the Dinopocalypse. They devour all other people indiscriminately and intend to wipe out every last non-dino human on the planet.
  • Ax-Crazy: They all really like dinosaurs, to put it mildly.
  • Combat Commentator: Taichiro does commentary for the King of Killing Bites tournament with Ui until he reveals himself as a Dinoman and attacks her. He's jumped by Oogami and his throat is torn off, but similarly to Brute Penguin he still keeps cheerfully narrating his own defeat and death.
  • Elite Mook: The story stresses that all of those random guys are as strong as Koyomi and that their horde is well capable of bringing about the apocalypse.
  • Horror Hunger: Taiga describes them as mindless animals that are constantly thinking about devouring their prey.
  • Mook Horror Show: Despite being dangerous, several of them get fought and easily killed by fighters like Lion, Tiger and Wolf, showing how unrealistic their omnicide goal is. This reflects rather badly on Koyomi, since they're supposedly as strong as her.
  • Omnicidal Maniac: 8000 people who are absolutely certain that they can kill a million people each to annihilate mankind and take over the Earth.

     Mutsujirou Uzaki 
An odd man who raises beastmen children in an orphanage. He gives all of them the family name "Uzaki".
  • Chekhov's Gunman: Similar to the appearances of a Shotaro Ishinomori expy in the author's Caterpillar, Mutsujirou is introduced in the animal funfacts scenes as the man who took care of Hitomi, Nodoka and Koyomi for Shidoh when they were little. Towards the climax of the story, he appears from out of nowhere to pacify Koyomi's henchmen in order to make her fight Pure fairly.
  • Combat Commentator: He oversees the climatic match between Pure and his "daughter" Koyomi.
  • Dissonant Serenity: He gleefully talks about how a young Koyomi bit some of his fingers off. Later on, in the middle of a genocidal takeover of the planet, he happily jumps on a bunch of raptors to tame them. Somehow it works and the creatures are left rolling around like puppies.
  • No Celebrities Were Harmed: He's based on real life zoologist Hata Masanori, whose pen name is "Mutsugorou".


Spin-off Characters

Characters appearing in the Hotter and Sexier spin-off series.

     Beastman Health "Sakaripark" 

Seiichi Todoroki/Brute Walrus


  • Ascended Extra: He has two appearances in the main series, getting quickly defeated both times. His role in the Hotter and Sexier spinoff is expanded, with Ui taking a job at a "health center" he runs in the red-light district.
  • Gag Penis: His massive walrus dong appears in Ui's spinoff, barely censored by a mosaic.
  • 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.

Akakuma Rasuka/Beast Raccoon


Natsumi Tako/Brute Octopus


  • Combat Tentacles: Her tentacles are strong enough to be used against other Brutes, and not just in a sexy-fun way. In the main series, she disables a Bulldog guard with her tentacles.
  • More Deadly Than the Male: The narrative invokes this trope, noting the female Octopus is the more cunning and dangerous of the pair. In their case, Natsumi looks sweet and gentle while her lover looks like a creep, but she's by far the more capable of the pair.
  • Ugly Guy, Hot Wife: Her partner is a skinny, balding guy that looks kind of creepy, while Natsumi is the #1 mistress at the store. They're both octopi, so it's probably not about looks for either of them.

     Uma Health "Pretty Jockey" 

Uma Health

  • Bland-Name Product: The names of the "Mares" are changed just enough to avoid issues with copyright over actual race horses.
  • No Celebrities Were Harmed: Parodies of famous Japanese race horses, and a certain other series based on horse girls.
  • Take That!: Their presence in the spinoff is Murata taking the piss on the R-18 ban imposed by the staff of Uma Musume and the narrator calls horse-girl characters inherently erotic because of how humans have learned to manipulate the estrus cycle of mares. Murata himself is known to have been fine in the past about what little H-doujin works based on Arachnid exist, by the way.
