Hayate Tenma

Hayate is Kurou's older brother who wants to get everything that belongs to Kurou because he believes that Kurou must die. Hayate will do anything to get his mother's attention, but because his other brothers outdo him easily he's out of luck. He has a liking for professor Kamako, but he doesn't realize that professor Kamako is a transvestite and no one seems to tell him.
