For Aya's timeline, see here.
Aya is a young, pale-skinned, adult girl with golden brown hair and green eyes. When she's not singing in the concert, she's usually seen in what appears to be a school uniform attire, consisting of a white dress, yellow tie and a pink overcoat. If she has to sing in a concert, Aya will wear a white popstar dress and a pink overcoat with a pink tie on it.
Aya is quiet, lonely, innocent, friendly, clumsy, smart, kind, loving, brave and caring just like her father. She gets sad whenever her mother dies.
- Aya is the only female character in the film. However, she is followed by Ellie.
- Aya has her own musical theme unlike her father.
- Her name means "colorful".
- In Aya Fredricksen, Matome Mayonaka, Arisa Ahokainen, and Niwaka Denkigai have a sleepover, it shows that she has the cutest laugh, very ticklish feet and cute wiggly dragon toes when being tickled on her feet and toes by feathers.
