Relationship with Oboro: She was in the same class as Oboro and Guest in high school. She was secretly in love with Oboro and approached him when Guest moved to Tokyo. However, once Guest started returning home every summer, Oboro realized he couldn't give up his feelings for Guest and broke up with her. They dated for about two years, but they rarely acted like lovers; they kissed so few times you could count them on one hand. She is still in love with Oboro as an adult. She can't forget the expressions he made. She wanted to see the face he shows to Guest. Her jealousy makes her act harsh toward Guest.
