Kuchisake Onna

Kuchisake Onna is a Japanese legend, for those who don't know or don't understand Basically she will walk over to someone with a mask over her mouth and ask them if she is pretty, if the person says no she kills them but if they say yes then she takes off her mask revealing a horrizontally slit mouth up to the cheeks and will ask the person "Am I pretty now?" If the person says yes she lets them live but if the person runs away or says no she then slits their mouth just like hers Also I think I might've got a few details wrong so correct me
