渋谷 隆造

A middle-aged man who works as a clerk at the academy.

He usually acts seriously, but his true nature is that of a pervert who is easily excited by schoolgirls.
He has honed himself in order to be near his favorite schoolgirls. He is full of vigor and does not go down no matter how much times he ejaculate.
He tends to ejaculate even when talking or smelling a girl, and so he wears a condom on a daily basis.

Ryuzo is unpopular with the students because of the thick smell of his semen and his suspicious actions he displays on campus.
