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.

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!

Following an accident on the job, Satsuki's father is injured, but Leo thinks ghosts are behind it. When the gang investigates the building Satsuki's father worked at, they find that the building itself is alive, and eager to have guests stay... for all eternity!
