Misuzu is the first of the three girls featured in Air that meets Yukito Kunisaki. She becomes friends with Yukito and invites him to stay over at her house. Her foster mother is Haruko Kamio who is actually her aunt as her biological mother died while she was still young and her father gave her to Haruko. She is a cheerful, slightly clumsy girl, and often mentions the pseudo-dinosauric phrase "Gao" whenever she feels troubled or is about to cry. Since a young age, Misuzu has had a great love of dinosaurs, going so far as to believe baby chicks were young dinosaurs for a time.
