Kashiwagi Aki

A former famous child idol, but for some reason her fanbase abandoned her as she got older.
She might look like a cute twelve-year-old, but she's got the cunning mind of an adult! She was raised in the cut-throat entertainment biz and won't hesitate to manipulate others to accomplish her goal of becoming the number one idol in the nation.

"Of course I'm the best twelve-year-old idol in the business, I've got seven more years of experience than the rest!"

Spoiler

She was the center of the child idol group "Strawberry Pink". After turning 14, the producer of "Strawberry Pink" arbitrarily graduated her via announcement and selected a new center. She became twisted from being exploited by her producer, and sold out by her own mother, having to experience the harsh corporate world since elementary school.
