Shinya Satou

A male student in Class 3, Year 6 at Kamohashi Elementary School.

An honor student who excels both academically and athletically; he is the ace of the soccer team. He has many female fans and is particularly plagued by the stalking antics of a trio of girls who are hopelessly infatuated with him. He is so popular that photos of him have even appeared at auctions.

He shares a relationship with Futaba Marui that allows them to talk openly and without reserve. He often spends time with Yuudai Chiba, though he sometimes ends up being the guinea pig for Chiba's "lewd techniques."

He frequently finds himself caught up in trouble involving underwear; this led Futaba to mistakenly believe he has a fetish for it. Furthermore, Airi Ogata—in a bizarre twist—became jealous of his underwear, disposed of it all, and has forced him to go without any ever since.
