Ikkou Satonaka

Is the main character of the series. Ikkou is able to release a powerful but uncontrollable power when confronted with his earthly desires. Each time, the aftermath of his awakening, he will bear a face of lust and will "attack" Chitose, who always responds with attacks that knock him out. He is always gutless when it comes to the girls he lives with. Especially with the case of Chitose. He is what would be figuratively called a doormat even up to the end of the second season. In some episodes he is struck by the other characters more than a half dozen times before the halfway part of an episode. Sometimes he brings it on himself but for the most part he takes it like an idiot. (Source: Wikipedia)
