Aggressive Retsuko (ONA) 3rd Season

After a painful breakup, Retsuko escapes into a mobile game and spends far more than she can afford. A small accident then connects her with Hyoudou, the hard-driving manager of an underground idol group, who offers a way to repay what she owes by handling the group's accounts. The job does not stay behind the numbers for long. Hyoudou discovers the death-metal voice Retsuko keeps hidden and pushes her toward the stage. Her days split between ordinary office work and a world built on image, visibility, and intense fan attention. Being noticed gives her confidence she never expected, but it also brings dangers she never faced when singing was a secret in a locked room.
