The Yuki-onna is an Effect NPC found in Snow World. Named after the Snow Woman of Japanese folklore, she bears a blank white face, long blue hair, and a pale blue kimono. She spawns somewhat close to an igloo, northwest of the Snow World's door. 
Interaction
Interacting with her for the first time gives you the Yuki-onna effect. Otherwise, she will normally walk away from Madotsuki, with the exception of the standard reaction to the Cat, Knife, and Stoplight effects.
Trivia
- She looks exactly the same as Madotsuki does while using the effect, but smaller.
- Her name in the English version is "Snow Woman". The same name is given to the Yuki-onna effect.
