Chihaya Ayase is a determined schoolgirl who "possesses a remarkable hearing ability". She believes that by persevering in karuta, she will meet Arata again, and begins a karuta club at her high school with Mashima. While she is beautiful, she is considered too weird, her classmates referring to her as a "waste of a beauty". She has been described as a "tomboy trapped in a supermodel's body". Her "guileless" nature has been criticised as seeming unrealistic by Shigeko Matsuo of the Asahi Shimbun, but Bamboo Dong feels that her "pure, sweet" characterisation "just works", although Dong feels Chihaya's attachment to Arata and Taichi is "a little weird". Chihaya is extremely childish, and when she was younger, looked very much like a boy due to her short hair. She has a pronounced sense of right and wrong, which causes her to befriend Arata when the other kids made fun of him.
