Areum "Aria" Choi is the straight man of the group. She is relatively normal and is more rational than everyone else. Despite living rent free and offered to have all her schooling paid for by Azreal, she continues to work two jobs. Perhaps she likes that it makes her miserable, but most likely its that she prefers the sense of accomplishment from doing good work with her own hands. Aria has always aspired to be an Idol and works towards that goal with Eisei who helps were with composing song covers. Whenever she is not working, or doing school work or procrastinating on uploading music, she can be found tinkering with the various machinery around the mansion. Engineering was something her father wanted her to persue which is why she knows so much. Or she could be browsing blogs she does that a lot too.
