!Akira Inugami
->Voiced by: Creator/ToshiyukiMorikawa (in the OAV's based in the original manga from TheSeventies)

The main character and one of the last remaining werewolves, Inugami has drifted through life on tides of misfortune, carrying a disdain for humanity and an uncanny ability to avoid death. He strikes up a bond with his new homeroom teacher, the kind and beautiful Ms. Aoshika, despite himself and what he's gone through. So, Inugami goes through the story facing characters that seem to lose themselves by his sheer presence, and trying to make sure that his bad luck doesn't rub off on on Ms. Aoshika.
----
!!Tropes that apply to Inugami:

* AnimalMotifs - Wolves. Yes, even when he's not on all fours.
* {{Badass}}
* [[spoiler:BackFromTheDead: While all his family and friends think Inugami died after killing Haguro, in truth he was taken to a lab, Phoenix Organ seems to have kidnapped to perform experiments]].
* CelibateHero: Inugami, much to Ryuuko's dismay. Though he could simply not be interested in any girl his [[LikesOlderWomen age.]]
* DeadpanSnarker
* {{Determinator}}: [[spoiler: So Aoshika's been kidnapped, brutally gang raped, it's the day of the new moon and Akira is as weak as human now. Plus, he got stabbed by Ryuuko and the wound is likely fatal. What to do? How about: [[UpToEleven run miles to find the warehouse Dou is keeping Aoshika trapped in, leap an eleven foot tall fence in a single bound, kill two Dobermans with his bare hands, completely wipe out a group of guards despite being fired at by a gatling gun that fires 2000-4000 rounds per minute, survive explosions from anti-tank mines, and sneak into the compound to reunite with Ms. Aoshika?]]]] The guy goes [[UpToEleven above and beyond]] to save his lady.

* HotForTeacher: The only (living) person he shows affection to is Aoshika-sensei. Guess what happens soon...

!Akiko Aoshika
->Voiced by: YukoSasaki (in the OAV's based in the original manga from TheSeventies)

A troubled middle school teacher, who is saved by Inugami from a gang of thugs. She's somewhat nosey, more interested in proving herself right that Akira Inugami is a werewolf and less in that she's dealing with a ''werewolf'', but is otherwise genuinely worried for her student's mental wellbeing. Concern turns into more complicated things, especially when their student-teacher relationship warps and she falls within range of Inugami's magnetism for mayhem.
----
!!Tropes that apply to Aoshika:

* BeautyEqualsGoodness: The most beautiful person in the manga and one of the few with a fully-functional moral compass.
* BreakTheCutie: A kind-hearted HotTeacher in a CrapsackWorld? It'd be more surprising if it did not happen.
* BrokenBird: Seems to have rape in her BackStory. [[spoiler: She gets even more broken later on, specially when Hagurou decides to use her as bait for Inugami... as well as having her gangraped. ''Repeatedly''.]]
* ChristmasCake: Although she was married once, but got divorced recently. She lampshades it in her drunken rambles before she meets Inugami.
* GagBoobs: Ms. Aoshika's so well-endowed it's almost silly.
* FanDisservice: Seeing her in her lacy undies should be a reason to {{squee}}. [[spoiler: Not when she's chained to a wall, and about to be brutally gangraped by Haguro and his goons.]]
* [[spoiler:HappilyFailedSuicide: As if being gangraped, drugged and recorded throughout the second half of the manga wasn't enough to push her over the edge, her before her much-needed rescue, Aoshika tries to jump off the hospital's terrace when she hears about Inugami being dead; she is stopped by a wolf who resembled Inugami, and she realizes that he could be alive somewhere and that she has to live in his place and honor; in truth the wolf was Jin, Aoshika discovers this by herself and talks to Jin in Alaska about it, thanks to this she now can recognize each wolf individually and finds a new respect for them, that's where she decides to live in Alaska]].
* HotForStudent
* HotTeacher: One of the most beautiful women in the whole series, if not the prettiest.
* LadyAndKnight: The (very beautiful but also very broken) Bright Lady to Inugami's White Knight.
* MoralityChain: For Inugami. [[spoiler: Once Haguro finds out...]]
* MsFanservice: We do see her taking showers a lot.
* PluckyGirl: After her rescue, and despite all of the horrific things that she has been through, Aoshika picks herself up and presses on.
* SoBeautifulItsACurse: She believes that her body is the cause of all the bad things that happened to her.
* [[spoiler:ThrowTheDogABone: Aoshika finally seems to experience a true recovery this time, after getting to know about Inugami's past, she decides to live in Alaska, at a preservation site, where Inugami was raised by wolves. The wolves accept her presence and starts to know them better, her body is looking healthy and she is smiling again, also she seems to know wolves so much now that when Inugami woke up at the Phoenix Organ lab, Aoshika immediately noticed something]].
* YankTheDogsChain: [[spoiler:Great, Aoshika is saved, but at the moment Inugami is taken for dead; which made Aoshika sink ''deeper than when she was getting gang raped'', she is not eating anything at the hospital, she can't take Inugami off her mind, and now her body shows signs of malnutrition]].
* [[spoiler: YoungerThanTheyLook: With everything that happened to her between her kidnapping and rescue, the poor woman has visibly aged quite a bit by the end of the series.]]

!Dou Haguro

The scariest ninth grader you'll ever meet. Son of a {{Yakuza}}, who develops a... [[FoeYay fixation]] on Inugami sparked by their being near total opposites. Where Inugami is a deliberately passive physical monster that gains a MoralityPet, Haguro is a destructive human being that abuses those closest to him. As the story progresses, this contrast becomes more stark and he grows the more monstrous of the two. Which is his whole intention: to be a true monster. A werewolf around just means he'll have to kick it up a notch. Or twelve.
----

* AnimalMotifs - A hawk. Special mention goes to his eyes, which are black where they should be white.
* AttentionWhore: His motives are best summed up as "How the hell can I get that werewolf to look my way?!" And he persists in this behavior even when his resources would be better spent doing anything else.
* AxCrazy
* {{Badass}}: Cements his status as one when he [[spoiler: takes down Ogre-Chiba with just a sword.]]
** BadassInANiceSuit
* BadBoss: Just as dangerous [[YouHaveFailedMe to his allies]] as he is to his enemies.
* BigBad
* BlackEyesOfCrazy

* CrazyJealousGuy: Do ''not'' go near Inugami. You ''will'' regret it.
* CreepyMonotone: Haguro seems to speak that way, initially at least.
* DepravedBisexual
* DevilInPlainSight - Subverted. Black sclera'd eyes, monstrous strength, emotionless carnage, but ultimately human and vulnerable as such.
* DissonantSerenity: [[spoiler: Until Inugami breaks his mind.]]
* TheDreaded: Students have a massive OhCrap moment when they hear he is coming back to school.
* EvilCannotComprehendGood: Subverted in one case. Haguro quickly figures out Inugami has at least one altruistic bone in his body and goes after [[spoiler:Aoshika.]] Played straight in that he wants to be Inugami's WorthyOpponent but doesn't understand what would make [[JerkWithAHeartOfGold Inugami]] think such a thing about someone.
* {{Expy}}: Looks a bit like a younger and more emotionless version of [[BakiTheGrappler Yujiro Hanma]].
* {{Gonk}}: Haguro looks damn near demonic.
* [[spoiler:HoistByHisOwnPetard: As it turns out, [[ImpaledWithExtremePrejudice katanas aren't just better]].]]
* InferioritySuperiorityComplex: Arguably. Haguro was, without a doubt, the strongest and most feared teenager in the city... [[AlwaysABiggerFish until Inugami showed up.]] Can't have that.
* InterplayOfSexAndViolence: Does this a lot.
* KatanasAreJustBetter: As befitting a Yakuza.
* [[spoiler:KilledOffForReal: ''Finally'' meets an appropriate end after all the shit he pulls.]]
* PowerBornOfMadness: the reason behind his seemingly inhuman strength
* ShonenHair: Kinda like {{Akumetsu}}. [[EpilepticTrees Wait a]] [[ShadowArchetype second]]...
* SlasherSmile: Some of his expressions in later chapters seem inspired by ''TheManWhoLaughs''.
* TheSociopath
* TheUnfettered
* [[spoiler: VillainousBreakdown: Has an epic one after seeing Inugami's true form.]]
* [[spoiler: VillainousValour: When he makes a stand against Ogre-Chiba.]]
* WorthyOpponent: Wants desperately for Inugami to see him as one.
* {{Yandere}}:Takes this to Nightmarish levels, and probably makes even [[MiraiNikki Yuno Gasai]] seem tame in comparison.
* [[YakuzaPrincess Yakuza Prince]]
* YouHaveFailedMe[=/=]YouHaveOutlivedYourUsefulness: If you are employed by him, good luck. You'll need it.
* YoungerThanTheyLook: He's roughly two meters tall and looks like he's in his late twenties. Lampshaded by Inugami in chapter 11.


!Ryuuko Kounuma

Haguro's very beautiful, but also extremely messed-up girlfriend. Her interests include destruction, sadism, brutality, and having sex with the man that can deliver the most of all three, so long as it's not in her direction.
----

* AxCrazy: Whatever your definiton of "crazy bitch", she's proabably not far off. If she is, you're trying too hard.
* BrokenBird: See what repeated rapes ''from her dad and a pimp'' and living in a CrapsackWorld can do to a teenage girl: leave her broken and insane.
* CloserToEarth: She's slightly less crazy than Haguro, if only because she realizes [[NeutralFemale the limits of her own flesh.]]
* DeathBySex: Save for Haguro, the men who sleep with her are all dead. Including her rapist dad and the pimp. [[spoiler: After Haguro's death, Ryuuko goes into a kill frenzy, she stabs to death two men who were having her "services"]].
* [[spoiler: EyeScream: Haguro punches her in the eye at one point.]]

** FanNickname: Miss Fan Disservice.
* FilleFatale: The creepiest version ever possible.
* TheFriendNobodyLikes: Seems to have no genuine friends or admirers whatsoever throughout the entire story.
* [[spoiler:GreenEyedMonster: Later chapters seem to imply she's envious of Aoshika for being the one Inugami loves.]]
* TheImmodestOrgasm: '''''HellIsThatNoise.'''''
* InLoveWithYourCarnage: She likes her men hot, sexy, and BadAss.
* MyGirlIsASlut: Not that Dou had any actual feelings for Ryuuko, but he didn't seem to have a problem with her seducing other men and actually encouraged her to seduce Inugami.

* PerkyGoth: A completely disturbing example.

* TheSociopath

* HardWorkHardlyWorks: This is the only thing ([[IfICantHaveYou besides]] [[CrazyJealousGuy Haguro]] [[MurderTheHypotenuse obviously]]) that kept him and Inugami from being friends: the fact that Chiba could train forever and never be as strong as Inugami and Haguro.
* HomoeroticSubtext: Haguro thinks he has this with Inugami, [[spoiler: so he beats him half to death and rapes him.]]

* BadassLongcoat
* ChronicHeroSyndrome: Jin explains to Aoshika that werewolves can sense a human's sadness or call of help, while no other human can; and in some cases the good ones ''feel obligated'' to help the human, or at least try to ease their pain a bit.
