The school play is coming up, but the boy in the lead role is scared; he makes a wish for the gymnasium to catch fire, and it does; when the play moves to being held in the old schoolhouse, the boy wishes to be injured and he is.
While in the old schoolhouse, Satsuki hears a haunting melody drifting through the halls; the only trouble is the lack of a pianist; if Satsuki hears the melody a total of four times, she'll die; the gang saddles up to put the ghostly piano to sleep.
Stories spread about something preying on children who are all alone, and the gang gets scared; especially since their parents will be out for the night; a deadly ghost with a sickle in hand stalks Satsuki and her friends.
People all over town begin acting strangely; most of them have been replaced by mirror-world clones of themselves. With Satsuki and Hajime being the last two people in the town who haven't been swapped, they'll have to find a way to end this ghost.
Leo is convinced that there's a ghostly website out there on the internet and is determined to find it, which he does; trapped in the computer, the rest of the gang needs to figure out how to apply old-fashioned exorcism to new technologies.
