As Takumi was making his way back down the stairs, he heard a loud crash from behind him. He turned around to see that the trapdoor had slammed shut, as if someone had pushed it from below.
Takumi tried to open the trapdoor, but it wouldn't budge. He was trapped, alone in the dark cellar. He tried to call for help, but his phone had no signal. He was completely cut off from the outside world.
As the minutes turned into hours, Takumi's fear began to grow. He heard strange noises coming from the walls, and the air grew colder and colder. He felt a presence in the room with him, but when he turned on his flashlight, he saw nothing.
