Ryuuzen Gotou

Ryuuzen Gotou (後藤 龍善, Gotou Ryuuzen) is a teacher at Yamaboshi High School and also acts as advisor to both the Jazz Band and Cultural Research Club. In addition, he is the homeroom teacher of Class 1-C, which includes Taichi, Iori and Inaba. Gotou comes off as a bit lazy and goofy but he can be quite insightful when he wants to be. He likes his students to feel at ease around him, so he allows them to refer to him by his nickname, "Mr. Go".
