Hotaru Ichijous lifestyle completely changes when she leaves Tokyo and moves with her family to the isolated Asahigaoka village. Her new school has only five students including herself, all sharing a single classroom regardless of grade level. There are no convenience stores in the area, and it can take up to two hours for a bus to arrive.

Nevertheless, Hotaru finds herself captivated by the countrysides charm thanks to her four unique schoolmates with whom she quickly forms a genuine bond. The most colorful of them is Renge Miyauchi, a first-grader who is often perceptive despite her age. However, no less intriguing are the three Koshigaya siblings: the quiet oldest brother Suguru, the petite older sister Komari, and the prankish youngest sister Natsumi.

Having someone from the city join their cheerful little group enlivens the ordinary days in Asahigaoka. Not only does Hotaru bring firsthand knowledge from the alluring outside world, but her fresh outlook on life welcomes a blossom of change to their usual routine.
