Kokubu Kokubu  

Sensei, 国分

The head teacher of Hinata Kawamoto's middle school is named Kokubo-sensei. He also serves as the interim homeroom teacher for Hinata's third year class, 3A. This class has a notorious reputation for having driven their previous homeroom teacher to a breakdown and resignation due to bullying by female students. In order to combat this psychological contagion that threatened the entire school, Kokubo-sensei disbanded the source of the problem, which was the girl bullies, by reassigning each member to a different homeroom. Before stepping down as the interim homeroom teacher for class 3A, he had several philosophical conversations with Megumi Takagi, the lead bully.
