Seemingly spending his life trying to keep Hakufu out of trouble, Koukin gets dragged into battle by his unruly cousin at every opportunity! Kind hearted and street wise, he is staying with his perverted aunt who seems to enjoy making him blush as much as possible. Koukin could be an accomplished fighter, but only his confidence seems to be holding him back from winning important battles and increasing his status.
