You play as Miku Hinasaki who goes to find her brother Mafuyu (who went to find his mentor, the novelist Takamine) in the Himuro Mansion. The mansion has a pretty bad reputation as the entire family, servants and all, were horrifically murdered by the master of the house around the turn of the century. Oh, and apparently they were also performing some mysterious Shinto rituals. Of course, Miku can't wait to rush in and find her brother, even from a mansion with such a bloody past where are least four other people have already gone missing. And, of course, Miku goes alone and at night. That's a horror survival game for you.
The main baddie is a ghost named Kirie who tries to kill Miku several different times (as do most of the ghosts). Miku must free all the spirits in the mansion of the evil malice that permeates the grounds in order to escape.
The story is actually really interesting and watching it unfold through scraps of paper and audio recordings is fun (and scary!). While it may be a bit out there (not as far out as Silent Hill) it was creepy enough to make me jump (a lot).
