Kazama Shiro

Husband of Kazama Yumiko and father of Akane. He is more than 10 years older than Yumiko.

At the time of their marriage, he was a teacher at another school, but last year he started working as the vice principal at Seitei Gakuen.

He has already lost his sexual desire for women, and his relationship with Yumiko is almost sexless. He is a strict man and strictly enforces school rules and student management.

Compared to his decline through the years, he is nervous about his white cheating on him, whose beauty does not match her age.
