Yuki Onna is Rikuo's trusted attendants. She follows him to school under a human guise known as Tsurara Oikawa. As her name indicates, she is a Yuki Onna youkai. Around the Nura House, she sometimes acts as a cook who makes delicious but usually chilled or cold food. Her eyes are dark blue while in human form and golden while in youkai form.

She is fiercely loyal to Rikuo and will do anything for him. She gets visibly jealous when Rikuo mentions Kana and loves Rikuo deeply, though it is not clear if her love is romantic.
