Aoi is a calm and bright girl. She is very intelligent, possessing an encyclopedic knowledge and excellent analytical skills. She is highly determined towards her goals and approaches them very seriously. Aoi makes sure to plan ahead and research as much as she can for a situation. She is hard-working and has a bit of a perfectionist streak.

As a child, Aoi quickly became interested in idols after discovering the freedom and excitement of it, which was a strict contrast to the traditional arts she partook in. Since then, she has dedicated herself to idols and has studied idols ever since. She appears to be quite lucky as she is seen throughout the series meeting several idols she is a fan of. 

She is known for being much more mature than Ichigo and tends to keep her on the right track, but has times when she can get very excited. While normally she seems confident and in good spirits, deep down Aoi is afraid of the fact that she knows it's possible she and Ichigo won't both rise to stardom together as planned.
