Hiten is a Thunder Demon and the older brother of Manten. While Manten looks like a monster, Hiten appears to be a handsome human. The reason Hiten looks human and Manten looks like some kind of shark-man is that their parents were two different types of demons. Hiten looks like their father and Manten looks like their mother. While he may be the better looking of the two, he's also the more psychotically violent as well.
