Kenjirou Tateyama

Kenjirou Tateyama (楯山 研次朗 Tateyama Kenjirō) / Kenjirou (ケンジロウ) is the homeroom teacher of Momo, father of Ayano, and husband of Ayaka. He formerly taught Haruka and Takane in a class for physically ill students.

Appearance

 * Kenjirou has brown hair, black eyes and a stubble below his chin.
 * He is always seen wearing black glasses, a white lab coat over his red striped shirt, dark jeans, and dark brown shoes. He also wears a pair of red clips on his shirt.

Personality
Kenjirou cares deeply for his family, including his adopted children Tsubomi Kido, Shuuya Kano and Kousuke Seto. Despite losing his wife and eldest daughter and now living alone, he still continues to do his best in educating students. He is Momo Kisaragi's summer school teacher and gives her both stern and kind guidance, as he understands that she is often busy with her new idol career.

Kenjirou seems to care deeply about his own reputation - especially with the principal of the school that he works at - so much so that he will go as far as sleeping only two hours a night to prepare for a cultural festival in less than a week and do whatever Takane asks of him in order to stay in the principal's good books.

Kenjirou's snake, however, is evil and malicious. Because Kenjirou is its "master", it intends to obey his desire, which is to meet Ayaka Tateyama again. It possesses him at night to do this and can go through drastic extents to reach its goal, such as killing Kenjirou's precious students Takane and Haruka Kokonose. His eyes turn red when possessed and he has no memories of what it does when possessing him. The nightly possessions also take a toll on his body, making him tired during the daytime.

Eye Ability

 * Clearing Eyes (目が冴える Me ga Saeru): Kenjirou's eye ability allows the Snake of Clearing Eyes to take possession of his body once the sun starts to set so that it can work towards his wish to see his wife again. However, he is unaware of the snake's motives or what it does when possessing him. It is eventually revealed that the snake's true plan is to force Marry Kozakura to rewind the world without granting his wish.
