Tokyo Majin

Tatsuma Hiyuu, a skilled martial artist, transfers to Magami Academy in Shinjuku during his senior year. He quickly befriends Kyouichi Houraiji, the class delinquent, and others, including Yuuya Daigo from the wrestling club and Komaki Sakurai from the girls' archery club. Their lives take a drastic turn when the Ryumyaku, a flow of arcane energy, is disrupted by an unknown force. This causes them to develop supernatural abilities and receive a warning from Hisui Kisaragi, the young heir of the Kisaragi Clan, about their duty to protect Tokyo from Oni, or demons.
