Man his wife is adorbs. While I love her younger form cuz if how cute she is I do like both forms. Wish older form kept her white hair she would be perfect.
I am not a Japanese nor a Japanese folklore expert but there are many versions of a Yuki-onna. And this is one of her versions, as mentioned by other people.
In the Iwate and the Miyagi Prefectures, a yuki-onna is thought to steal people's vitality...
One of the common or typical portrayals of Yuki-onnas would be the cold girl, without the sex. They're not entirely the equivalent version of succubus all the time. Well, if I remember correctly, people made smut versions of every Japanese folklore creatures/monsters back in the day. ( ͡° ͜ʖ ͡°)
I wonder if the idea of yuki onna as succubi is inspired by paradoxical undressing, where people on the verge of death from hypothermia sometimes strip down for no apparent reason. It's as a good a reason as any for finding naked frozen corpses.
