Intro
Guest has come to the school pool alone at night. The surroundings are pitch black, and the pool water is cold. In the depths of the area, a single massive shadow exists. It looks to be about 3 meters tall.
......? It seems he has noticed Guest. He tilts his head slightly and looks in this direction.
