Yoshihiko Zawa

Yoshihiko Zawa (ヨシヒコ) is a teacher at the school Kou Yamori dropped out of.

Appearance
Zawa is a tall man with short, bright-colored hair and glasses whose outfit always consists of a suit.

Personality
In school, Zawa has the reputation of a serious and no fun allowed adult, a reputation he rightfully earned as he doesn't tolerate students making jokes and interrupting his class, something that most teachers would overlook.

Outside of school, Zawa is a heavy alcoholic, drinking even after he has vomited, claiming alcohol to be the only fun he has, and saying that life as an adult is very dull. At night, his attitude is much more lax. He is very perceptive and knows that Kou was forcing himself to be an honor student, saying that he felt relief when Kou quit school and stopped forcing himself. Zawa admits that he hates both students and teachers and hated school since he was a child himself but still works there since he is proud of his job. School trips used to lift his spirit but in recent years, it has become more of a business-like affair for him.

He is single and has expressed interest in dating Seri Kikiyou after she clarified that she isn't an actual high-school student.

Abilities
As an average human, he doesn't possess any extraordinary abilities.
