Hiroshi Uchiyamada 内山田ひろし
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. He is easily enraged by Onizuka's behavior basically always. He seems to have no respect for school delinquents or any rebels during the series. Hiroshi 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 decision. Uchiyamada is always yelling at Onizuka's behavior and argues with him a lot.
