The student council president and the principal's granddaughter. She is popular with both men and women because of her appearance, but in reality she is quite the mischievous devil. She is bored because her day-to-day life remains completely same without any kind of change. But one day, she accidentally finds out about Souta's weakness and starts teasing him over it.

Spoiler

Her fetishes are being treated as a pet and becoming a public cum dumpster.
