This scary Japanese urban legend is extremely haunting. The legend tells about this Japanese girl who wears a surgical mask around her mouth, hiding the scary look. If she finds you, she will ask you if she's pretty, and removes her mask, revealing a slit-open mouth. If you say "no", she will kill you, but if you say "yes", she will slit your mouth too, so you can be like her. Legends say that if you say "maybe", she'll be confused, giving you a better chance to run from the woman.
