結城俊哉

He attends the private Sakuragaoka Academy, and is head of the world-renowned Yuuki Corporation. As head of a worldwide corporation, he is extremely busy, but still maintains a double life as Sakuragaoka's student council president. Blessed with both good looks and excellent grades, he is well-liked both by teachers and his fellow students (especially of the opposite sex). He comes off as the perfect student, but that is only a public facade he shows to the rest of the world. The real Yuuki Toshiya is a perverted sex maniac: an insatiable lover of blow-jobs with both sadistic and masochistic sentiments, not to mention a cosplay fetish! [from MangaGamer]
