Kazuma Sakagami

Kazuma Sakagami (坂上 数馬) is the homeroom teacher of class 1-C.

Appearance
Kazuma is a middle aged man of average height with grayish color hair.

He wears a gray suit and glasses.

Personality
Not much is known about Kazuma, but he appears to that of a sensible teacher as he helped his students in trying get Ken Sudō expelled. He has somewhat of a bullying side to him as he intimidated a nervous Airi Sakura after she was called in to provide evidence though he was shocked to see she had actual proof of being at the fight.

Plot
Kazuma appears in Ken Sudō's case where he proposes a compromise between the two classes.

Later, Kazuma serves as the facilitator of the Event Selection Exam for the battle between Class-A and Class-D (Class-C during the time of the special exam), alongside Chie Hoshinomiya. Due to the latter constantly speaking out of line, Kazuma has to keep reprimanding her.

Kazuma and Chie were both fooled by Kiyotaka and Arisu's play of dialogue during the start of the first event. During the Flash Mental Arithmetic event, both facilitators could not solve the ninth and tenth problem. During the final event, which is chess, Kazuma and Chie were completely taken in by the complex match between Kiyotaka and Arisu. After the special exam was over, Acting Director Tsukishiro came to usher out everyone, including the teachers, to which Kazuma protested that they had cleaning up to do, but Tsukishiro completely dismissed that.
