A hormonal, blonde-haired biker and virgin, Onizuka Eikichi graduated from a bottom-rung university by cheating and, as such, cannot get a decent job. His main way of spending time is peering up girls' skirts in a local mall. He is very athletic, as he can bench press 150 kg (331 lbs), has a second dan black belt in karate, and even claims to perform 500 push-ups, 1000 pull ups and 2000 squats daily.
