アリア・セレスティア

Likes: Gyoza, tea
Dislikes: Spicy things

Yuuto's very hardworking but scatterbrained upperclassman who loves gyoza a lot. Aria constantly attemps to be firm due to her status as the discipline committee's leader and because she's one of the older students. At the same time, she dislikes the fact that she constantly tries to behave according to others' expectations of her.

She is the descendant of an exorcist who was skilled in swordsmanship and came from a foreign country. However, her big breasts make it hard for her to properly swing a sword.
