The Idolmatster returns with the darker, grittier spinoff ironically called "Cinderella Girls". Cinderella Girls explores the shadowy side of the mega money making idol industry. Following fourteen girls from their start as brainwashed wide-eyed youths to their debut as carbon-copied mass produced eye candy, Cinderella Girls is a grim divulgence into the unknown practices that go into the making and marketing of idols out of innocent girls and an exposé of the industry as a whole.
