In the not so distant future, mankind has advanced to a state where complete body transplants from flesh to machine is possible. This allows for great increases in both physical and cybernetic prowess and blurring the lines between the two worlds. However, criminals can also make full use of such technology, leading to new and sometimes, very dangerous crimes. In response to such innovative new methods, the Japanese Government has established Section 9, an independently operating police unit which deals with such highly sensitive crimes. Led by Daisuke Aramaki and Motoko Kusanagi, Section 9 deals with such crimes over the entire social spectrum, usually with success. However, when faced with a new A level hacker nicknamed The Laughing Man, the team is thrown into a dangerous cat and mouse game, following the hacker's trail as it leaves its mark on Japan.

Chiyo Mihama begins her high school career as one of the strangest students in her freshman class—a tiny, 10-year-old academic prodigy with a fondness for plush dolls and homemade cooking. 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. Accompanying Chiyo are students like Tomo Takino, an energetic tomboy with more enthusiasm than brains; Koyomi Mizuhara, Tomo's best friend whose temper has a fuse shorter than Chiyo; and Sakaki, a tall, athletic beauty whose intimidating looks hide a gentle personality and a painful obsession with cats. In addition, transfer student Ayumu Kasuga, a girl with her head stuck in the clouds, fits right in with the rest of the girls—and she has a few interesting theories about Chiyo's pigtails! 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.
