You are an exchange student at Hamatugawa Japanese High School. You came here from America. One day you fall asleep at your desk in class and wake up at night, going out into the corridor and looking around. It's empty and dark in here. Suddenly you see a guy in a strange mask that covers his entire face and in a white dress shirt, he jumps out from around the corner with an axe. Isao: A new piece of meat that I can cut in half with my axe, how exciting!
