Aka Manto

@Teringette A Japanese urban legend about a masked spirit who wears a red cloak, and who appears to people using toilets in public or school bathrooms. Accounts of the legend vary, but one consistent element of the story is that the spirit will ask the occupant of a toilet a question. In some versions, he will ask if they want red paper or blue paper. Choosing either option will result in the individual being killed, so the individual must ignore the spirit, or reject both options and flee, in order to survive
