One night, the investigator woke up to find themselves trapped in a square room. In the center of the room, a single bowl of bright red soup sits lonely atop a desk. And on a chair lies a map of this room and a warning note that says, "Drink the poisoned soup." Trapped in this world by the whim of Chaugnar Faugn without even realizing it, will the investigators be able to escape this world safely? While living their ordinary, mundane lives, the investigators suddenly wake up one night. When they open their eyes, they are in a square room with concrete walls and floors and doors on all four sides. At this point, the investigators are unarmed, and the clothes they wear are nothing but rags resembling white robes. They have nothing else. No wallets or cell phones, of course, nor any accessories they usually wear. And strangely, within this world, even if the investigators are from different countries, they will feel as if they are speaking to each other in a common language. Only a dim nightlight on the ceiling illuminates the room, and in the center is an old wooden long table and a single chair. Furthermore, on the table is a single red, odorless soup in a wooden bowl, and two old scraps of paper have fallen nearby.
