Hailing from France, Aria is a rather soft-spoken character who has a tendency to cry whenever there is trouble, uttering the phrase "kusu" (an onomatopoeia for sniffling) when doing so. She enjoys sweets, especially parfait, and can usually be found wearing very frilly dresses with plenty of lace and bows. She refers to herself in the third-person, which is considered childish in Japanese culture, and speaks slowly.
