Chiyo Mihama , usually called Chiyo-chan, is a child prodigy, having skipped five grades to 10th grade (first year in Japanese high school) at the start of the series yet is still top of the class. Such grade-skipping would be unthinkable in Japan, and the series humorously explores its potential consequences. The other characters find Chiyo amazingly cute, but sometimes take advantage of both her youthfulness and her scholastic abilities. Her diminutive stature leads to her having a lack of confidence, particularly in sports where she fears she is a burden to others. Chiyo is frequently viewed with jealousy by fellow students, initially because of her intelligence, but later also because of the discovery that her family is exceedingly wealthy (they own an enormous mansion and a summer house which Chiyo invites her classmates to visit on several occasions). The stylistic rendering of Chiyo&#039;s pigtails allow for several visual gags in both the manga and anime: Osaka often imagines them to be flapping wings, or as entities independent of Chiyo herself. At home, she can almost always be found in the company of her enormous dog, Tadakichi-san. Of all of the girls, she is the only one who does not sit through college &quot;entrance exams&quot; as she intends to study overseas, possibly in America.

Ten year old child prodigy, Chiyo Mihama, is finding it tough fitting in at high school with the girls five years her elder: Osaka (dimwitted with a weird take on the world), Tomo (a powder keg that goes off at a moment’s notice), Kagura (the competitive athlete of the bunch), Yomi (the hothead), and Sakaki (timid and obsessed with a love of animals that isn’t reciprocated). Together with their teacher, they navigate the rough waters and fun times of high school.

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.

Notes: 
- A great number of chapters are divided into several parts that have been included in the final chapter count. 
- The chapter count includes 5 extra chapters.

In this short movie featuring familiar characters from Azumanga Daiou, Osaka is yet again having a strange dream of Chiyo-Chan's pigtails being posessed. As Chiyo-Chan's pigtails bounce out of the window, who knows if young Chiyo will ever be happy again.
