Moving to a new town is tough, 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 happens to be haunted by ghosts.

Something is stinking up the town, and it isn't just urban reconstruction; a ghost has invaded the school's bathrooms, and it's up to Satsuki and the gang to find out how to put it back to sleep; the old book left by Satsuki's mom just might be it.

The big 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 be 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; it seems that if Satsuki hears the melody a total of four times, she'll die.

The gang helps Keiichiro train for a sports festival at school; a mysterious boy shows up at the track, running alongside Keiichiro; despite the bonding between the two, it seems the new boy isn't quite alive.

Stories spread about something preying on children who are 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.
