On the outside, Aya is very cheery, high-spirited, and bubbly. She is also very nice and has always been in love with idols. She is unselfish in her pursuits, helping others for the sake of being kind. Deep down, however, she is a sensitive girl who suffers from a complex stemming from her desire to be noticed. Adding to this, she does not wear her disguise outside because she wants to get noticed, and even looks up constantly what people think of her on the internet. She gets worked up easily and tends to cry a lot, thus her improvisation skills are poor.
