Hotaru Ichijou's lifestyle undergoes a complete transformation when she departs Tokyo to relocate with her family to the secluded Asahigaoka village. Her new school consists of merely five students, including herself, who all share a single classroom irrespective of their grade level. The area lacks convenience stores, and bus arrivals can be delayed by up to two hours. Despite this, Hotaru becomes captivated by the countryside's charm, largely due to her four distinct schoolmates with whom she quickly establishes a genuine connection. The most vibrant among them is Renge Miyauchi, a first-grader who displays surprising perceptiveness for her age. Yet, the three Koshigaya siblings are equally intriguing: the reserved eldest brother Suguru, the petite older sister Komari, and the mischievous youngest sister Natsumi. The arrival of a city girl into their cheerful, small group breathes new life into the ordinary days of Asahigaoka. Hotaru not only provides firsthand insights from the enticing outside world but also introduces a fresh perspective that sparks a subtle shift in their usual routine.
