Synopsis
Non Non Biyori takes place in the countryside, where the nearest bookstore is a 20-minute bike ride away, a certain magazine "Ju_p" comes out on Wednesdays instead of Mondays, and the video rental store is 10 stations away. Hotaru Ichijō then transfers from Tokyo to this school and readjusts to the slow pace of life in the countryside. His classmates are Natsumi, Komari, Renge, and Komari's older brother, Suguru, who is in his third year of high school.
The manga was then released in 2009.
