Tomoharu is a normal high school student... except for the fact that he is never alone. Haunted by the ghost of his dead childhood friend, he moves into a new residence at the beginning of the school year.

Life turns out to be a little more difficult than expected, though, when his house is overrun by various female occult users. To make things even worse he is pulled into an epic struggle to protect a mysterious trunk, that is presently hidden in the house.
