GTO (Season 0)

Through the introduction of his friend Danma Ryuji, Onizuka Eikichi, the former legendary bike gang member, visits Meishu Academy to tend to the trees in the garden as a part-time gardener. Learning that Yoshikawa Noboru, a student in teacher Fuyutsuki Azusa’s class is being bullied by Uehara Kyoko and other classmates, Onizuka befriends and saves Yoshikawa. Seeing Onizuka’s unprecedented but visceral, powerful response to problem solving, the school’s president and principal, Sakurai Yoshiko, overrides resistance from her vice principal Uchiyamada Hiroshi and makes Onizuka a teacher. Onizuka goes on to tackle many issues as the teacher in charge of the most problematic class, Class 2-4.
