People all over town begin acting strangely, but it isn't their fault, as most of them have been replaced by mirror world clones of themselves! With Satsuki and Hajime the last two people in the town who haven't been swapped, they'll have to find a way to end this ghost, before they end up in the mirror!

Convinced that a ghost is haunting a train crossing, Leo takes the gang out to try and catch the spirit in a photo. When one of those photos shows a strange hand on Momoko's shoulder, things start getting bad, and a tale of revenge unfolds.

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?
