From MangaHelpers:

This 4-koma style comic follows the high school life of Nazuna. She's attending an all girl's high school that is way up on a hill from the nearest station. The bus is infrequent, so simply getting to school can often be a challenge. At school, her friends include someone she met at the entrance exams, an odd girl named "Tsukushi," after the school name, and who has 2 chickens, "Colonel" and "Sanders." [tethysdust]
