Hiroshi Uchiyamada

Yoshiko's father and Vice Principal of Holy Forest Academy. He is a very strict man who readily blindly follows the school rules and places them on top of anything else. Also he doesn't have much patience. And loves his Cresta very much.

Hiroshi is easily enraged by Onizuka's behavior basically always. He shows to have no respect for school delinquents or anyway rebels guys during the series. He believes that Onizuka is the evil root of all his misfortunes. He was visibly against Onizuka's hiring, but had to accept Principal Sakurai's positive decision. Uchiyamada is always yelling at Onizuka's behavior and argues with him a lot.
