Moving to a new town is tough on kids. Nothing is familiar, and with no friends, it can be scary. In Satsuki's case, that last part isn't helped any when she, her little brother, and three kids from school end up in the old schoolhouse, which just so happens to be haunted by ghosts!

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?

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.
