Which takes place before the actual Azumanga Daioh anime happened. Where Chiyo Chan enters 3rd grade elementary school. She then meets Muruchi and Yuka. They become Chiyo Chan's friends throughout the anime. And throughout the plot, Chiyo Chan gets better and better at school and always gets 100% on her work as well as playing with Miruchi and Yuka, and enjoying elementary school. But then on the last episode she leaves elementary school on 5th grades and skips ahead to high school leaving her classmates Miruchi and Yuka, which makes Chiyo Chan kind of embarrassed. But she said that she will do good even if it's hard and is only for grown ups.
