Scary Japanese Urban Legends

Aka Manto (The Red Cloak)

Red Cloak hides in the last stall of the girls' toilet and when you enter, he steps out and asks "Which do you prefer, Red Cloak or Blue Cloak?"

If you say Red, he slits your throat or chops off your head and the blood flows down your back, making it look like you're wearing a red cloak. If you say Blue, he grabs you by the neck and chokes you until your face turns blue and you die of suffocation.

Don't even think about asking for a third color. If you do, the floor will open up beneath you and pale white hands will reach up and drag you down to hell.
