Complete Monster/Wolf Guy Wolfen Crest


 * Haguro Dou in Wolf Guy Wolfen Crest is one of the most horrific and despicable manga villains of recent years. He makes Femto (A GOD of EVIL) SANE in comparison. He manipulates the younger Kuroda into going Columbine on half the student body out of vengeance against Inugami for his older brother's death, using weapons from his family gun cellar. The kicker? His brother died because HAGURO pulled his life-support. It only gets worse from there.
 * Kuroda also took a break from blowing up stuff (and students) to try to rape an innocent girl named Noriko Kimura with his gun, and when she refused to go along with this, he tried to shoot her dead. Fortunately, Inugami interrupts him.
 * Also, Haguro beat his Noble Demon subordinate Chiba within an inch of his life, biting off his tongue, and then raping him for good measure to the point that Chiba ends up dying from a combination of ruptured organs, blood loss, and broken ribs. . Why did Haguro do such a thing? Because Chiba ended up encountering Inugami out on the streets and talked to him for maybe 15 minutes when Haguro wasn't around. Haguro is Yandere for Inugami's werewolf form, you see.
 * Also, he kidnapped and brutally raped Akiko Aoshika (a teacher who ends up falling in love with Inugami, becoming his Morality Chain) while recording it so that Inugami can see, practically talking to the camera (and, therefore, to Inugami) through the entire thing in the hopes that Inugami (who left to Nara due to Haguro's actions) will come back to him.
 * He not only rapes Aoshika:
 * Post Aoshika's release from her chains, Haguro tries to kill her, telling her that Inugami is too good for her. Inugami shows up in time to beat him up, and during the Inugami vs. Haguro battle, Haguro gets to slice off two of Inugami's fingers, and he eats them in an insane attempt to confirm Haguro is a superior beast to Inugami. It gets even worse when Haguro slices off four more of Inugami's fingers - and an entire arm.
 * Haguro also fired an MGL-140, which is a semi-automatic grenade launcher, at the school, thus committing the SECOND school shooting of the series. The attack hospitalizes Aoshika, and she later identifies him as the shooter.
