High Schooler Hosts Overfiend Amid Demon And Beast Clash

In a world where humans, demons (Makai), and half-beast beings (Juujinkai) coexist, a prophecy predicts the arrival of the Choujin Overfiend to restore balance. Amano Jyaku, a Juujinkai, discovers that high schooler Tatsuo Nagumo harbors the Choujin’s power. With his sister Megumi and ally Kuroko, Amano protects Nagumo and his girlfriend Akemi Ito from the Makai, who fear Nagumo may be a destructive force rather than the savior foretold.
