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!

The gang takes a trip to the mountains to stay at a resort run by Satsuki's cousin Miyuki. However, upon arrival, a young girl tells them that Miyuki is dead. It seems that her ghost still haunts the frozen lake, turning it blood red. But this story might not be as simple as it seems...
