Something evil is stirring in the shadows of Tokyo... During the spring of his senior year in high school, quiet Tatsuma Hiyuu transfers to Magami Academy in Shinjuku. The mysterious boy's "outsider" status and his profound skills in martial arts quickly earn him the friendship of class delinquent Kyouichi Houraiji.
