Oh kuchisake onna. I became obsessed with Japanese urban legends several summers ago. And have been in love with them ever since although I think I've gone through most of the more famous ones. I basically know the major ones by heart. So I have a pretty good chance of surviving an encounter with her. But for people who don't know here's how to survive. She usually attacks you by asking you am I pretty. if you say yes she'll remove her surgical mask and slice your face like hers. If you say no she'll straight up kill you. if you say am i pretty she'll stop to think about it and you can runaway. You can also say I have prior engagements to get to and she will politely excuse herself.
