The quintessential honor student; she speaks politely to everyone and was apparently the Student Council President during her 2nd year. But, she is a pervert, a closet lecher, a masochist, and full of worldly desires.

Uses "-san" or "you" for everyone.

Created it to understand the importance of sleep. She says, "One-third of life is spent sleeping, so I want to make it a high-quality life."

Very clean and stylish. Uses a light blue eye mask.
