Chiaki Onizuka is a senior at Masaru Kato 's high school who boxes professionally in the heavyweight division. He is openly homosexual, as noted by Kazuki.

Appearance Edit

Onizuka is tall dark-skinned, short black hair. It has a cut in the direct sombracelha, to wear earrings in the two ears.

Personality Edit

Onizuka is evil and arrogant who use his height and skills in boxer to fuck the asshole of other guys. And you're not ashamed to admit that you're gay.


Pre-Tanaka Alien ArcEdit

Onizuka expresses a desire to rape Kato presumably after the juniors (most of whom Kato stopped earlier from taking a weaker students' pants and who plan to beat Kato up) are finished beating him up. Kato is enraged when he is informed that Onizuka plans to rape him, and instead beats Onizuka, who is unprepared while occupying a bathroom stall, into a bloody mess, apparently partially as a message to the juniors to "stop bullying those who are weak."

Shion Izumi ArcEdit

Later, while Daizaemon Kaze is searching for the strongest warriors in Tokyo, Kaze is informed that Onizuka is the strongest fighter in the area (despite the fact that he was easily defeated by Kato) and issues a challenge to him. Many students come to see the fight (held in the bathroom where Onizuka was defeated by Kato), believing Onizuka capable of easily defeating Kaze. However, Kaze quickly defeats Onizuka and effortlessly tosses him out of the bathroom.


  • In the manga, Onizuka has his pants and underwear down when Kato beats him. In the anime, only his pants are down.
