In the past, the school had a sinister headmaster who sought a sacrifice fueled by human obsession. He lured a student named Adam—who was obsessed with his classmate, Sarah—by giving him a cursed bag, claiming it would grant his wish and make her love him. The moment Sarah touched the bag, she transformed into a monster and ended up slaughtering Adam. The headmaster then cut out Sarah’s tongue to bury the secret with her; however, the curse struck him as well, turning him into another monster that feeds on the voices of the school’s visitors. Be warned: the sounds you hear inside the school are not mere illusions—they are the footsteps of the headmaster as he hunts for you. You must find the cursed bag before you become the next victim.
