Japanese Urban Legends

Aka Manto

Appearance:

Aka Manto was a good looking man in life. He was constantly stalked by admirers. In death he wears a mask and red cape.

Story:

Aka Manto appears as a mysterious voice in the last stall of a bathroom. He asks "red vest or blue vest?". If you answer red you will be sliced apart until your clothing runs red. If you answer blue you will be strangled until your face turns blue. If you try to trick Aka Manto by answering another color you will be dragged into the netherworld. The only answer that leaves you safe is "no vest".
