Sakura Yamazaki has just returned from her stay in America, and the priestess considers Momiji Fujiyama an enemy. Sakura thus challenges Momiji to a singing contest -- at a studio with a number of Aragami attacks.
Momiji is an average girl until the day she finds she is the descendant of the great Kushinada family. Only she, with her Kushinada blood, can stop the Aragami, demonic plant-like monsters threatening to destroy Japan. Along to help her is the TAC, and a possible love interest in a young man named Kusanagi.
