Kokoro Kosaka is shocked when her recently deceased classmate comes back to life in the form of a stuffed wallaby toy! How will she handle this new companion and what are his reasons for returning from the dead?

Yotsuba's daily life is full of adventure. She is energetic, curious, and a bit odd—odd enough to be called strange by her father as well as ignorant of many things that even a five-year-old should know. Because of this, the most ordinary experience can become an adventure for her. As the days progress, she makes new friends and shows those around her that every day can be enjoyable.

A laid-back high school comedy centering around the daily lives of several characters, including ten-year-old genius Chiyo, space cadet transfer student Osaka, cool but shy Sakaki, overloaded with energy Tomo, responsible Yomi, and sporty Kagura. Also taking part are irresponsible English teacher Yukari, dependable gym teacher Nyamo, honest but extremely perverted Mr. Kimura, and a mysterious yellow cat-thing who may or may not be Chiyo's father.

To celebrate the 10th anniversary of Azumanga Daioh, the manga is being repackaged into a new three-volume set, which will include three chapters of new material called Supplementary Materials.

Each new chapter covers one year of high school, with all new adventures for Sakaki, Yomi, Tomo, Chiyo, Osaka, and Kagura.

Parody manga of Bishoujo Senshi Sailor Moon by Azuma Kiyohiko.
