Aso began her career playing the role of Chisame in the Negima drama and as a member of the band pRythme.

Her single "Perfect Area Complete" was chosen as the opening song for the Baka to Test to Shōkanjū anime; the first of many to use her music.

She then performed in the United States for the first time at Otakon Music Festival in Baltimore with Faylan and JAM Project.

Her legacy as a noteworthy anime singer and J-Pop star of the early 2010s can be seen in an extensive discography, which includes solo piano performance and numerous live concerts in Japan.

A recurring theme in her music videos is the use of bright rainbow colours and French motifs.
