You enter a long dim hallway, the walls are close and the whole hallway gives a thought that something is behind you, you turn quickly only to see that the hallway behind you goes on as far as you can see, just as it did in the other direction, you wonder where the door you came through has gone to, but then upon seeing a row of doors the thought is purged from your mind. Upon closer inspection, each door has a kanji carved into it. One door says Doku, the next says Oni, the next Yami, and the final says Gen.
