The "local heroine fighter" of a certain city became popular and a national star. Because of this, "local heroines" debuted in various other places, and their action live events became a hit trend nationally. In Hinano City, high school girl Misaki Shirogane and other girls become local heroines (at the urging of Misaki's aunt, the prefectural governor) and vow to produce action live events.
