Chiyo Mihama begins her high school career as one of the strangest students in her freshman class—a tiny, 10-year-old academic prodigy. But her homeroom teacher, Yukari Tanizaki, is the kind of person who would hijack a student’s bike to avoid being late, so “strange” is a relative word. There certainly isn’t a shortage of peculiar girls in Yukari-sensei’s homeroom class. Together, this lovable group of girls experience the ups and downs of school life, their many adventures filled with constant laughter, surreal absurdity, and occasionally even touching commentary on the bittersweet, temporal nature of high school.
