Far from the urban hustle and bustle, with only a single candy store and bus route to its name, rural Asahigaoka is certainly not a place for everyone. Nevertheless, the village's children still manage to cheerfully spend their days exploring and having fun in the surrounding wilderness. One such child, Renge Miyauchi, the youngest of the group, looks forward to the entrance ceremony of the upcoming school year, which signals her entry into first grade and the beginning of her elementary school life. Attending the only school in town, Renge and her friends—seventh grader Natsumi Koshigaya and her eighth-grade sister Komari—make the most out of their rural lifestyle, playing and studying every day. Meanwhile, fifth grader Hotaru Ichijou has just moved to Asahigaoka from Tokyo, unaware of the numerous adventures and memories that await her.
