I've wanted to do kuchisake onna for Halloween for years, so here goes! It's a Japanese urban legend about a beautiful wife of a samurai, whose mouth was slit by her husband after he found out about her infidelity, scarring her forever. Her ghost is said to still roam around, and on a foggy day a woman in a surgical mask would appear and ask: 'Do you think I'm beautiful?' Then she would remove the mask, showing the horror beneath, and ask 'How about now?' And then she would kill them with scissors.
