Kuchisake-onna is a Japanese urban legend about a woman who wears a surgical mask and asks people if they think she is beautiful. If they say no, she kills them with a pair of scissors. If they say yes, she removes her mask to reveal a mouth slit from ear to ear and asks again. If they say no, she kills them. If they say yes, she cuts their mouth to look like hers. The legend has been passed down for generations and has inspired movies, books, and even video games.
