While in the old schoolhouse, Satsuki hears a haunting melody drifting through the halls. The only trouble is the lack of a pianist! It seems that if Satsuki hears the melody a total of four times, she'll die. The gang saddles up to put the ghostly piano to sleep.

Leo is convinced that there's a ghostly website out there on the internet, and is determined to find it. Unfortunately for him... he does! Trapped in the computer, the rest of the gang needs to figure out how to apply old fashioned exorcism to new technologies.

The gang finds a strange doll in the trash. Satsuki prevents Keiichiro from bringing the doll home, but it shows up regardless. And then, late at night, Satsuki gets a phone call from none other than the doll herself! With the doll stalking her relentlessly, how will she ever be rid of it?

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?
