a 2015 Japanese anime television series produced by Wit Studio. The logo of this title contains the text, "Rolling, Falling, Scrambling Girls. For others. For themselves. Even if they're destined to be a 'mob'".Ten years after the end of the "Great Tokyo War" that rocked Japan, most of the country's political and economic elites mysteriously vanished. As a result, the country split up into the original 10 prefectures that soon became independent city-states that competed with each other. Many vigilantes who fought in the aforementioned war became hired as the "Best" (mosa), representing their prefectures in territorial disputes. Their supporters, the "Rest" (mob), work to support them while maintaining the peace within their respective prefectures.

After a prolonged battle with Kuniko leads her friend, Masami to become seriously injured, a rookie Rest named Nozomi decides to travel around Japan on her motorcycle with her new friends, fulfilling requests for Maccha Green while they seek to grow stronger and search for special heart-shaped jewels, the moonlight stones. It is said that the moonlight stone can make a person possesses unlimited power when it is worn, especially by Bests of different regions when combat or fight happens in order to protect themselves, but may lead to serious consequences such as injury of people and damage of properties because of the force emitted by the battle or the people who used it. In reality, it is used as a fuel by aliens in outerspace to operate their spaceship.
