Aoba Moca is a third-year student at Haneoka Girls' High School and the lead guitarist for Afterglow. She has a sleepy demeanor and speaks with a slow, monotone voice, but is surprisingly sly at times.

Although everyone in Afterglow are childhood friends, she is particularly close to Ran. Outside of the band, she's friends with Saaya. She is also friends with Lisa, whom she works part-time with at the same convenience store.
