I'm a huge fan of Azumanga Daioh, mostly for the characters. But even though it's to this day the most popular anime (up there with The Melancholy of Haruhi Suzumiya, Lucky Star, K-ON!, and others), it didn't get any spin-off unfortunately (unlike The Melancholy of Haruhi Suzumiya and Lucky Star). And I would love to see some be made as both mangas and animes so bad. Here are some I though about:

*Sakaki & Kaorin: Like Azumanga Daioh, it's a slice of life comedy anime taking place after the six girls graduated from high school. But then when 4 of the girls split up because of changes, Chiyo Chan and Osaka were the only two girls who were still hanging out with each other. Untill Kaorin was told by her mother she should get a house of her own and someone to take care of her. Then she came to Sakaki's new home and decided to live with her to do some work for her and to protect her from danger. Then Chiyo Chan and Osaka came to their house and wanted to live with them and Kaorin doesn't mind and they live with them. Then they meet their lesser known friends from high school and elementary school who are Chihiro, Hiroka and her friend Mizuki who have been friends to the girls since Azumanga Daioh are now Sakaki and Kaorin's best friends and most of the time give them jobs to do with other female students from their high school, Miruchi & Yuka who were Chiyo Chan's classmates from back in grade school are now Chiyo Chan and Osaka's best friends, Mr. Kimura and his family are now Sakaki and Kaorin's neighbors since they live next door to their house, and Yukari and Nyamo are now the helpers to Sakaki and Kaorin. Throughout the whole anime, the plot is just the girls enjoying life in the real world (almost like Lucky Star). Kimura's Wife is named Oku and Kimura's Daughter is named Nuka.

*Azumanga Preschool (prequel): 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.

The series would feature at the end of each episode a short 3 min. cartoon series called "Hot Runner & Dawn Coyote" a Road Runner & Wile E. Coyote knock-off.

*Azumanga College (prequel): Taking place before Azumanga Daioh, the two teachers Yukari & Nyamo were first classmates in college. They both become rivals at first but then suddenly becoe friends in the middle of the anime. Their goal is to become high school teachers (of course Yukari learning about different languages in order to become a language teacher and Nyamo learning how to be a P. E. teacher. After they finally finish college near the end of the anime, they finally become high school teachers.

Do you guys think that those would be good ideas? Just reply to me at anytime.
