Chihiro (千尋) is a classmate and friend of Kaorin. Little is known except her name. When she appears, she is usually keeping Kaorin company, and she collaborates with her on some projects. Once, when Chiyo-chan tutored her, Yukari assumed it was the reverse. Occasionally Chihiro bears the brunt of Kaorin's temper, without knowing why; it is unclear how aware she is of Kaorin's crush on Sakaki. Chihiro was also one of the most disgusted by the cockroach that appeared in class in Episode 2. In the manga, during the senior year sports festival Chihiro dressed as Chihiro from Spirited Away, partnered with another student (possibly Kaorin) dressed as Kaonashi from the same film.
