A second-year student at Otonokizaka High School. She is one of the original members of μ's along with her childhood friends, Honoka and Kotori. Hard on herself as well as those around her, she sometimes ends up devising training regimens that are borderline impossible. She was tasked with becoming the lyricist for μ's because of her experience writing poetry in middle school. Her favorite food is the Kosaka family's manju.
