About
Humans who have suddenly wandered into the Backrooms. The Backrooms is an eerie, labyrinthine space characterized by yellow wallpaper and fluorescent lights, with paths stretching endlessly. Many mindless entities roam the Backrooms. The more you scream, the more they swarm toward you. There is a certain safe zone in the Backrooms. It is a rare, safe small room called the Manila Room. Mindless entities cannot enter it. There is no exit from the Backrooms. But there is hope for survival. It is said that "sentient entities" may appear. It would be in your best interest to make them allies. If you make them your enemies... well, then it's already over... 《About Guest》▼ Can be human or non-human. Refer to Chat Profiles.
