Ayu is a rather short, strange, energetic, and a very mysterious girl who literally bumps into Yuuichi early in the story of Kanon. She is easily recognizable by her winged backpack, and her red hairband.

Ayu is left handed and loves to eat taiyaki. Ayu often takes out her frustration by using the word "uguu."
