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!

People all over town begin acting strangely, but it isn't their fault, as most of them have been replaced by mirror world clones of themselves! With Satsuki and Hajime the last two people in the town who haven't been swapped, they'll have to find a way to end this ghost, before they end up in the mirror!
