Azumanga Daioh, K-On!! Recommendations
K-ON!! is an anime that clearly takes a lot of inspiration from Azumanga Daioh and resemble eachother in a lot of ways. While Azumanga is a lot more silly and K-ON is a lot more realistic, there's lots for fans of either series to enjoy. Fun, lighthearted slice of life with plenty of hilarious comedy between the characters.
Both of these animes are very character driven with great comedy and art. They just make you smile and are a joy to watch.
Azumanga Daioh, like K-ON, is also a slice of life comedy about a group of high school girls going about their everyday lives. Many of the characters are similar where you have a tomboyish loud one, a shy quiet one, a cute younger one, an eccentric one, and a couple more that fit somewhere in between. The characters also have a friendly relationship with their teachers like that in K-ON. After watching Azumanga Daioh, it's not hard to see the influence it has on anime like K-ON.
