Airi Sawagashi

Airi, a wealthy girl, is a classmate and friend of Mamoru and Yūna. She discourages any relationship between Yūna and Mamoru, because, according to her, childhood friends who become lovers are generally unsuccessful. However, this may be a ploy since she has feelings for Kagemori, whom she derisively calls 'Ahoru' ("Mamoron"). She occasionally gives Mamoru hints that she likes him, which he is oblivious to, and she vents her frustration by hitting Mamoru.
