Azumanga Daioh, Vol. 2(2000)

Kiyohiko Azuma

It's not manga, it's Azumanga (and it's smart, fun and totally addictive)! Created by the iconoclastic Kiyohiko Azuma (hence the name), Azumanga Daioh is strongly character driven, telling the story of a group of high-school girls and their hilarious daily tribulations.
