Metanorn:"Nagisa, Orine, Yuuka, and Chieri are four young girls living in a society where entertainment is banned. (What could go wrong?) With only each other for protection the four brave the sewers in order to reach a an immensely populated crowd of pedestrians waving and cheering. For what you ask? Only a super fabulous rainbow machine that holds the team AKB0048, a group of illegal idols bringing hope through their powerful songs."
