Satsuki falls in with a bad crowd, or it might be better to say coven. Several girls at her school conspire to cast spells together, and she reluctantly joins in. But when one of them goes missing, and no one seems to remember the girl's very existence, Satsuki knows this isn't just any ordinary fad!

The entire school is possessed and drawn into the old schoolhouse, all to lure Satsuki and the gang into a trap. Lord Ohma has awoken, and seeks vengence upon Satsuki for her family's past attempts to seal him. In this final confrontation, who will emerge?
