Japanese urban legends can be incredibly creepy.
This one is the worst because everything you do you’re basically screwed (pardon my French).
There’s this woman who walks around at night wearing a surgical mask.
In Japan actually it’s quite common that people wear these kind of masks when they are sick, it’s their way to be polite and don’t spread their germs, so you’ll see people with surgical masks all the time on the road, and it’s obvious that an urban legend would come out sooner or later.
So, you’re there walking on the street, minding your own business, when this woman meets you and asks you, “Am I pretty?”
If you say no, she kills you with a pair of scissors. Right away.
You of course say yes, so she removes her mask and shows you her face and you see that she has a deep bloody scar slicing open her mouth from ear to ear, and again she asks, “What about now? Am I still pretty?”
And again you have two possible responses.
If you say no, she kills you. She literally cuts you in half.
You want to be polite and say yes? She slits your mouth like hers.
Who is this woman? Someone says she’s a woman mutilated by her jealous husband.
You can’t run away, she will always reappear. Someone has suggested ways to avoid or confuse her, for example you can say “You look average”, or you can ask if you look pretty or even give her candy.
Just try, but I hope you never meet her.
They even made a few movies and mangas about her, if you want to have some fun ;)
