Injuu Kyoushi

Atsuko and Sayaka think they have it made when they are both accepted into the same prestigious women's academy. There, they will be free to explore the hidden desires on one another. But when the mystical bonds imprisoning a hideous ancient evil that feeds on the lust of nubile women are accidentally broken, the two young lovers soon learn they have more to fear than final exams. An evil monster that devours the freshmen and so the pervert administrations and teachers.
