Ultraman 80
Yamato's theory is that monsters are born of the energy created by negative human emotions, also known as Minus Energy. He decides to become a teacher at Sakuragaoka Junior High School in Tokyo, and serves as a science teacher, as well as the home room teacher responsible for 1st Year, E Division. He is absolutely dedicated to his students, for he is there to teach them not just about science, but also about life. Unfortunately, he has a penchant for being late, so he does things like promising his students to walk to class on his hands if he is late next time, or even promising to resign as a teacher. He even starts up a band with his students and jams on an electric guitar. His over-enthusiasm quickly wins the loyalty of his students, but often makes him an easy target for the prim Deputy Schoolmaster Kumi Nozawa. Yamato loves rice, bakso and orange juice. He also loves Kyoko Aihara, the gym teacher, but loses all confidence in himself and sense of composure in her presence. Yamato dons an orange and silver suit to moonlight at UGM (Utility Government Members), the regular Earth defense team, after school and on Sundays. He gets the job from Captain Oyama because they are both present at a park in the first episode, looking for signs of new monster activity. Oyama is happy to meet someone who believes in the re-emergence of monsters. Even his own team members had their doubts, since none of them have any combat experience like their veteran captain. At school, only Principal Kennosuke Hayashi knows of Yamato's extracurricular activities.
