Kamaitachi no Yoru

In Kamaitachi no Yoru Tōru and his girlfriend Mari are on vacation at a skiing lodge when they find themselves suddenly drawn into a horrible murder mystery. The player must solve the crime. If they are too slow in collecting clues, additional murders will be committed, and will eventually result in a horror movie-like ending. The goal is to complete the story and get a certain number of endings. When this happens, two more stories are unlocked. Getting every possible ending of all three stories will unlock two more stories, these being self-parodies. Completing these unlocks one final feature, a parody of Torneko no Daibōken: Fushigi no Dungeon. None of the stories are related to each other in any way, but they all feature the same characters.
