Fukumoto Ikurou

Ikurou is a student of class 2-F. He is nicknamed "Yonpachi" since he can name all 48 Japanese sex positions. He is good friends with Gakuto, Takuya and Suguru. Yonpachi is considered the most perverted person in Kawakami Academy, and he is always showing his perverted smile.

He always carries his camera around just in case he could take shots of the female students' panties, but he hasn't been able to take even one shot of the female members of the Kazama Family. However, in reality, he really doesn't dare to take shots of them because then they will kill him. Like most of his classmates he has bad relationships with the members of class 2-S, but he also wants to take photos of the girls of that class.

The unpopular boys (and a teacher) gather once a month in the gym after class. They call these meetings "Mouryou's Gathering". This gathering has a dark aura, and Yonpachi's the one who organized this union, he is known by the members of this union as "Emperor of Virgins". In this place, he sells the photos he took in an auction. He uses the earned money to buy porn magazines for the other members of the union.
