Aka Manto (赤マント Red Cape) is a Japanese urban legend about a malicious spirit who kills people at public and school toilets, who will ask people if they want red paper or blue paper. In some versions, he will ask the individual if they want a red or blue cape. Often described as a beautiful man in life and hounded constantly by admirers, he supposedly wears a mask to hide his face.
According to the legend,
If a person is sitting on the toilet (usually the last stall), a mysterious voice will ask them if they want red paper or blue paper. If they answer red paper, they will be sliced apart until their clothes are stained red. If they choose blue paper, they will be strangled until their face turns blue. Any attempt to outsmart Aka Manto by asking for a different color will result in them being dragged to the Netherworld. If you decline to receive any kind of paper, he will depart.
Aka Manto is sometimes referred to as Aoi Manto (Blue Cape).
Sometimes the voice will ask them if they want a cape rather than paper. If they agree to red, the skin on their back is ripped off to resemble a red cape. If they ask for blue, all the blood is drained from their body.
One popular version of the story changes the choice from red paper to a red vest:
Another version of the story says that if they ask for yellow cloak, they will have their head forced into the toilet they've just used but they will survive being drowned.
To avoid being killed
if he asks a question, don't answer until he says "no paper?"
then he will leave you and go away so you can finish your own business in the comfort room.
