Don’t let their knee socks and short skirts fool you: Kagura (Minori Chihara) and Yomi (Kaoru Mizuhara) are no ordinary Japanese schoolgirls. Descended from a long line of exorcists, the teenage siblings are thus destined to battle the demons of darkness themselves. This prequel to the "Ga-Rei" anime series recounts the girls' sword-slashing battles with malign spirits as well as the challenge that Kagura faces when Yomi is possessed by a demon.
