Fourth grader Ryunosuke lives in a dying remote village where the majority of the population is over 65 years old. He lives with his unemployed dad in an inn that has not seen a customer in years. Ryu meets a homeless guy who agrees to help Ryu in return for a hot bath at the inn. The homeless guy feels sympathetic to Ryu's situation and wants to help bring traffic back to the inn but without something like a young beautiful girl it seems hopeless. But as luck would have it, a falling idol Ayu wanders into the village. Now with all the puzzle pieces in place, Ryu, Ayu and the homeless man work to bring customers back to the inn.
