Aka Manto is a ghost from Japanese folklore. He takes the form of a tall high school boy who wears a red cloak and a white mask. He appears only in the third stall of the girls bathroom. If you ask for red paper, he will slash the skin off your back. If you ask for blue paper, he will suffocate you to death. The only way to get away is to tell him that you don’t need paper, or to show him a perfect grade on a test. He is a low-ranking soldier for king Enma and makes a living killing humans.
