Aka Manto is a spirit who haunts bathrooms, usually the last toilet stall in a women's or girls' bathroom.
Some versions describe him as wearing a mask to cover his extremely handsome face, which had caused him stalking problems in life.
When the unlucky victim is on the toilet, a mysterious voice will ask them if they want red paper or blue paper.
If you answer red paper, you are killed violently and drenched in blood.
If you ask for blue, you are strangled or bled dry, leaving your face/skin blue.
Attempting to ask for any other colour of paper will result in hands appearing (sometimes coming out of the toilet you are sitting on) that will drag you into the fires of Hell.
In other versions the ghost will simply ask you if you want a red vest and will then rip the skin from your back.
He could also ask you if you want a red or blue cloak. The only answer that will spare the person is to refuse anything he offers
