Azumanga Daiou: Hoshuu-hen is additional chapters for the reprint edition of the manga series Azumanga Daioh. Each chapter covers one year of high school and is included in a relevant volume.

It's not manga, it's Azumanga! &minus; smart, fun and totally addictive. Created by the iconoclastic Kiyohiko Azuma, Azumanga Daiou is strongly character driven, taking the reader through the daily tribulations of Miss Kurosawa, Miss Yukari, the wild Tomo, hair-triggered Yomi, ditzy Osaka, brash Kagura, cute Chiyo-chan and athletic (but girly) Sakaki.
