Futsuu no Joshikousei ga [Locodol] Yattemita.

In the town of Nagarekawa, Nanako Usami, an ordinary high school girl, is approached by her uncle to become a local idol or "Locodol," partnering with upperclassman Yukari Kohinata to form the idol unit, Nagarekawa Girls. As the girls use their talent to promote Nagarekawa and their businesses, they are joined by Yui Mikoze, who acts as the local mascot, and Mirai Nazukari, who serves as Yui's substitute.
