Kisaragi, Quon

如月久遠

Quon Kisaragi is a mysterious young girl who delivers the opening lines of the TV series and is depicted meeting Ayato in episode 4. Her typical expression of surprise or agreement is "Ra-ra" (or "La-la"), and much of her dialogue is cryptic and centered on musical themes. Although she and Ayato do not share a romantic connection, she exhibits a degree of physical and interpersonal comfort and intimacy with him that surpasses that of any other character, including Haruka. She is also among the few individuals who never regard Ayato as a curiosity or an annoyance; she appears to understand his circumstances and his eventual role, addressing him as Ollin ("motion" in Nahuatl).
Similar to Ayato, she bears the marks of a potential instrumentalist. Both she and Ayato are shown undergoing examinations, and when outside her home, she wears a vest-like device known as a Life Module. Quon is proficient in playing both the violin and the piano. She is also portrayed as curious about the music others listen to via headphones, frequently removing them to hear the audio herself.
