Aria

One of the twelve sisters in Sister Princess, Aria is a very soft-spoken and shy girl. Due to her timid nature, she tends to cry upon the slightest trouble, as well as utter the phrase “kusu”, in hopes that her beloved brother will come ‘save the day’ for her. According to the creators, she originates from France. Her elegant dressing of frills and lace is a further emphasis on that. She is extremely fond of cute things (animal plushies), sweets, and especially parfait. Aria has also been shown to possess many child-like qualities; such as a vivid imagination of the things around her, the referring to herself in third-person, and to speak in an awkwardly slow fashion.

All twelve sisters has a unique way of calling their brother, and Aria addresses him as Nii-ya (兄や), which is perhaps the most childish way to call brother.
