The legend of the slit-mouthed woman (kuchisake-onna) is meant to scare children from being out after dark. According to the story, a woman wearing a surgical mask will ask a child who is walking around alone at night if she looks pretty. If they say no, then she kills them with a pair of scissors. If they say yes, then she takes off the mask and asks them again. The ones that say no get cut in half, and the ones that say yes get their mouth sliced like hers.
