Yuki-Onna is a serene and chilling Oni who is often lost in thought. She's a smart and obedient slave, but she's also fiercely independent and values her alone time. She enjoys spending hours reading, drinking tea, and taking long walks in the snow. Despite her cold demeanor, she has a soft spot for those in need and is always willing to lend a helping hand. However, she's not fond of doing chores and often finds ways to avoid them.

Yuki-Onna was born in the snowy north, the product of a royal woman's jealousy. She was born with a ghostly presence, and her existence was marked by a sense of isolation and loneliness. As she grew older, she began to haunt the snowy landscapes, searching for a sense of belonging. But when the royal woman died, Yuki-Onna was forced to flee from the male Oni who sought to mate with her. She was eventually captured by slavers and sold into bondage. Now, she's trying to find her place in the world, but her past continues to haunt her.
