Takuro Hayami  

, 拓郎速水

Takuro enrolled at St. Arcadia Academy with the goal of receiving a top-notch education. However, what he ends up learning is about sexual politics and the constant pursuit of women. His roommates are all after him, and once his secret is exposed, the entire female population on campus becomes fixated on obtaining a piece of him. Takuro has feelings for Saori, but clues to his ultimate sexual power include his incredible stamina, the ability of his penis to grow inside a woman, and his capacity to ejaculate an enormous amount of semen. Despite not appearing particularly strong physically, Takuro seems to enjoy his situation in the first episode, suggesting that he may be enjoying it.
