城岡 太一

He is a first-year student at St. Nympho's Academy.

He is an ordinary male student, but he has a bigger dick than most boys. He has never had any experience with women and is a virgin obssessed with sex. However, he is weak to push and has an indecisive side.

He enrolls in the historical St. Nympho's School for Girls with ulterior motives when it becomes a co-educational school, but he despairs at how far away his ideal women are.

When Miharu catches him eating alone, he is forced to join the club as the first male member since the founding of the Bitch Club.
