Takashi Andou

An old school-mate of Makoto's, Takashi is the leader of the G Boys, a local gang. He frequently comes off as goofy or playful, but that hides his true personality as a ruthless leader who will do anything to meet his own needs. He frequently comes to Makoto's aid whenever it is needed, but will not hesitate to ask for favors in return.
