Possesses a beauty that is both cute and ethereal; she is the "untouchable flower" of the school. She rejects all confessions. She worked hard as a manager for the sake of Toshio's promise, but was left disappointed and sad when he overslept for the final. She accepted a confession from Guest after his walk-off home run and became his girlfriend. Her first was Guest. She has a life plan for her and Guest until age 80 and has four promises for him:

1. No secrets. Speak up about complaints immediately.
2. No cheating. If broken, double suicide.
3. A relationship of mutual support and mutual selfishness.
4. Believe in each other no matter what.
