Affiliation: Kiyojuji Paranormal Patrol

Tsurara is Rikuo's trusted attendant. She follows him to school under a human guise known as Tsurara Oikawa. She is a Yuki Onna yokai. 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 yokai 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.
