Hiroshi Uchiyamada


 * The vice-principal at the Holy Forest Academy, and the Mr. Wilson to Eikichi Onizuka's Dennis the Menace, Hiroshi Uchiyamada is commonly seen throwing fits over two things: Onizuka the "parasite", and his beloved and frequently-totaled Toyota Cresta.
 * According to a self-explained biography in the manga, Uchiyamada was born and educated in a small rural town. He was discovered as a prodigy and recommended to become a teacher at the Tokyo College of Education, where he first met his wife-to-be, Ryōko. 29 years of hard work eventually earned him his current house and position at the Holy Forest Academy. His daughter is Yoshiko Uchiyamada.
 * Uchiyamada holds very conservative ideals on how peoples' backgrounds determine their future performance. Despite his attempts to thwart Onizuka's plans, Uchiyamada is not so much a classic villain than merely dogmatically serious about the job of teaching (at least in his mind). He is a not-quite-extreme example of the punishment an ordinary, older middle-aged, Japanese man takes from his home and workplace. He is forced to work with a young man like Onizuka, who easily breaks the rules and does things that don't make sense to him. His superior, Headmaster Ryoko Sakurai, seems to think it is fun to have a presence like Onizuka. At home, his wife, daughter, and dog openly disdain him in his often deluded imaginings, and feels that they're only satisfied with the luxuries that his work earns.
 * Uchiyamada eventually accepts Onizuka's views of teaching, when the latter yells at and punches Uchiyamada, when he interferes with Onizuka, trying to save Urumi Kanzaki, on the verge of death, for the sake of his job. With Onizuka's help, he also reconciles with his family, though he remains viciously defensive, when Onizuka tries to make a move on his daughter.
 * A running gag in the manga has Onizuka constantly destroying Uchiyamada's Cresta, mostly as a side effect of rescuing students, such as falling from the top of the school building and landing on the car. Another running gag involves Uchiyamada frequently getting injured, or assaulted by accident, from an oblivious Onizuka.
