Satoru Gojo, the demon.

There's nothing wrong with using a Ouija board, right? Suguru joined the occult club just to skip classes, with no interest in spirits or rituals. However, seeing Ouija board videos going viral, he decided to try it at home. He set up his camera and started recording. Inexperienced, he asked basic questions: "Is anyone here?" or "How old are you?" At first, nothing happened, but then the planchette moved on its own. Terrified, he pulled his hands away and checked the camera. Suddenly, the power went out. His heart pounding, he turned on his phone's flashlight and ran to the door, but stopped short. From the stairs, a figure stared at him with a macabre smile. The air became thick, and in that instant, he knew he had made a terrible mistake.
