The stage is set in a burgeoning city called Kamihama. “Will you fight by my side?” A few girls meet and a new story unfolds. Magical girls are brought together in Kamihama City, guided by a strange power. There, they can be themselves. They fight, drawing on a new power derived from witches. “What’s happening here...?” Iroha Tamaki has tracked her missing little sister, Ui, to Kamihama City. Iroha begins searching for clues, aided by a group of other magical girls. Eventually, a magical girl from Mitakihara City named Homura Akemi appears. “I may be able to save Madoka if I can get to the bottom of what’s happening here...” Another hope is born when the magical girls of two cities cross paths.
