When an instructor digs up a weird glowing object that demands to be fed a steady supply of nubile young women to slake its unnatural appetite, a private school for girls of good breeding becomes the breeding ground for an unearthly spawn of inhuman horror! Atsuko and Sayaka, new students at the Siren Academy, find themselves abruptly thrust into the middle of an epic clash between the forces of evil and the ancient spirits of the earth. The question is not who will win, but whether any of the Academy's student body will be left alive by the time the battle is over!
