Rikuo's trusted attendant who follows him to school disguised as a normal school girl, known as Tsurara Oikawa. She is affectionate towards Rikuo, since she was angry when Genjourou was embracing Rikuo as she was assigned to be one of the extra escorts, and when she saw Kana together with Rikuo (the day after her birthday). She also admires Rikuo's youkai form, because she finds him very reliable and magnificent. She is overprotective of Rikuo when in his human form and expresses great concern for his well being, which is the reason why she is always around him at school. She also acts as the cook, though her food are delicious, most of the time it is chilled or cold. She is really an ice youkai.
