Satoshi Miwa

The student body president and a third year student. Many girls are interested in him, but he is only interested in Meiko, and tries to get her to like him in place of Na-chan. His crude sense of humor however, do not sit well with Meiko, who believes him to be irresponsible and a playboy. Satoshi is the first person to notice Yuu's interest in architecture, and his initially unusual behavior towards Yuu arouse Yuu and Miki's suspicions that he is gay and has a crush on him, which he uses to his advantage.
