A schoolmate of [[Kuroki Tomoko]], she went to the same middle school that Tomoko and [[Naruse Yuu]] studied in.  She and Tomoko generally don't get along much (because they're so alike), but they tolerate each other for Yuu.

She has a massive crush on [[Kuroki Tomoki]]. [[Itou Hikari]] is her closest friend in school.
