The Crimson Labyrinth (クリムゾンの迷宮, Kurimuzon no Meikyū) is a novel by Japanese author Yusuke Kishi published in 1999.

The main protagonist, Fujiki awakens to find himself in a strange desert landscape suffering from amnesia.

While attempting to recall the foggy circumstances surrounding his arrival in the mysterious landscape he comes upon a woman named Ai.

Once the players reunite it becomes apparent that they have all chosen to act selfishly and hold out on each other so Fujiki decides not to share all of their new found information.

The following day everyone parts company but Fujiki and Ai decide to remain as a team and focus on honing their survival skills.

Fujiki eventually discovers that the entire game is constructed in the manner of a gamebook and that the nefarious purpose of their captors is to pit the players into a bloody contest against each other in order to create an elaborate snuff film from which only one is permitted to emerge alive.
