Aka Manto is an urban legend from Japan. It is rumored that in the last stall of the girl’s bathroom Aka Manto waits for his next victim. He wears a mask to hide his beautiful face and wears a cape.
While doing your business, a ghostly voice will ask if you’d prefer the red paper or the blue paper. If you choose the red paper you will be killed violently and drenched in your own blood. The blue paper will have you either strangled or all your blood drained until you turn blue. If you try to fool Aka Manto by choosing a different color, his hands will reach up and pull you down into the netherworld. Some say the only way to escape is by refusing anything he offers. You could also just choose the yellow paper and have your head pushed into the toilet you’ve just used.
