The student council president and a second-year student. She is serious, diligent, and talented in most subjects. However, she is almost always thinking of perverted things, even suggesting that one of her main reasons to be interested in Tsuda is curiosity about information not covered in health classes.

She later develops some feelings for Tsuda.
