High school girl Nanako Usami became her town Nagarekawa's local idol at the request of her uncle. She and her upperclassman Yukari- a girl who seems perfect but ends up being air-headed- both become idols of their provincial area. They get interviewed (by the town's shopping center), go on television (low-budget cable), and hold concerts (on the roof of the department store). The girls' salaries come from the town's taxes. Together, the two form the "locodol" unit, Nagarekawa Girls.
A dream of falling from the sky...and then birth. Rakka is born from a large cocoon into the Old Home, greeted by a group of females with small wings on their backs and shining halos above their heads. Soon Rakka's own wings grow, a halo is placed on her head and she is told that she must work in the nearby town of Grie. She soon realizes that the town and the entire world they live in are confined behind the Wall, a tall, impenetrable wall that none except the mysterious Toga are allowed to exit.
