Aka Manto

Aka Manto (赤マント; "Red Cloak"), also known as Red Cape, Red Vest, Akai-Kami-Aoi-Kami (赤い紙青い紙; "Red Paper, Blue Paper"), or occasionally Aoi Manto (青マント; "Blue Cloak"), is 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 or blue toilet paper, though other versions identify the choices as a red or a blue cloak, or as a red or a blue cape. 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.

Just as the individual is about to wipe, he will ask them "Red toilet paper or blue toilet paper?". If they choose red, he will slash them, resulting in a quick death with their clothes being soaked red in blood. But if they choose blue, he will strangle them, resulting in a slow death while turning their face blue.

If an individual tries to trick him by saying yellow, he will dunk their head into the toilet water and hold them there until they drown.

If an individual says another color other than red, blue, or yellow, they will be dragged to the underworld.
