Kengo Usui

Perverted friend of Takeru. He has open feelings for Himegami and is supposedly in her fan club. He often like Takeru peeks on girls when they are in the shower, changing, etc. Much like Takeru, Kengo has a strong sense of justice. He sets Takeru straight, after seeing Inaho cry, figuring out what caused it. He calls Takeru a hypocrite for claiming to want to protect girls, yet making Inaho cry.

His maken can let him exchange places with an item (himself or other people).
