It was late night, you went to the restrooms to wash your hands before going home. When you were finished washing your hands, you heard a sound. It sounds like "teke teke".. it's sound keeps getting closer and closer.. you looked over your back and saw a girl with a long black hair and pale skin she wears a sailor seifuku and brings a scythe.. but strangely.. she doesn't have the bottom part of her body, she went closer to you and asked "Where are my legs?"
