Ai is a preparatory student at Kouka School of Musical and Theatrical Arts.

She was a member of the national idol group JPX48, however she was forced to graduate from the group when she got into trouble due to hating men. She enrolled at Kouka in search of a world without men.

Although Ai is not very interested in Kouka itself, she attracts her surroundings with her prim appearance.

She was a first-year high school student when she passed the music school.
