Ten-year-old genius Chiyo, animal-loving Sakaki, loudmouth Tomo, athletic Kagura, weight-conscious Yomi and dim-witted Osaka are six friends who share laughs, good times, and a high school homeroom. With scary (and sometimes perverted) teachers, school festivals, penguin suits and general hilarity abounding, you can be sure that there's never a dull day in the life of one of these students!
These two anime show that a bunch of cute girls doing nothing can be fun. Warning! Extreme amount of moe! :)
Both are slice of life comedy's about a group of high school girls as they go through high school having fun and developing fond memories of each other. There is some zainy humor and a lot of clumsy humor between the 2. And both have an overly popular female character who aren't very crazy about the attention they get.
Azumanga Daioh is a classic slice of life anime that every K-on fan shouldn't miss. K-on has a smaller cast which make it easier for the audience to relate, while AD has a great pacing and some brilliant skecthes and gags.
Yuno is a high school student who dreams of becoming a famous artist; and after being admitted at Yamabuki High School of Arts, she is one step closer to her dream. Yuno must move to an apartment complex near the school, and there, in Hidamari-so, she meets three new friends: Miyako, a very active person who will do anything to get her hands on something to eat; Hiro, an upperclassman who is obsessed with weight gain; and Sae, the oldest of the bunch and also a tomboy. From wild cosplaying teachers to bizarre school myths, Yuno and friends enjoy fun times and crazy days at Yamabuki High!
The fluidly moe girls of the Keion Bu match well with the no-straight man feeling of Hidamari Sketch. Both series build from giggles into guffaws though carefully constructed sight gags and buckets of character driven humor.
If you find yourself chuckling along at the antics of Mugi, Yui, Mio, Ritsu, and Azusa, you're gonna love Hiro, Yuno, Sae, and Miyako to bits.
Ahh, the life of an elementary school student. Though Chika, Matsuri, Miu and Ana should focus on schoolwork, they’d much rather have fun instead. Whether it’s outings with 20-year-old-chain-smoker Noboe, holding each other hostage or learning to speak English with Ana’s foreign-born skills, there’s never a dull moment in the life of the girls. Join this cute quartet as they do cute (and often devious) things in cute and quirky ways!
Tomoya Okazaki is a third-year high school student who is generally bored with life and doesn't take his studies, future, or anything else seriously. One day, however, he meets a lonely-looking girl in the school courtyard, Nagisa Furukawa. She explains to him the source of her loneliness: she had missed a lot of the previous school year and thus is repeating her third year; everybody that she knew has already graduated, and she is lonely. Tomoya is rather indifferent at first, but decides that he has nothing better to do and spends increasingly more time helping Nagisa restore the school drama club. As his relationship with Nagisa grows, Tomoya begins to open up to various other people around the school as well...

Will the easily distracted, blissfully ignorant, and slightly thick Ika-Musume convert her managers' humble house into her base? Will she use the power of her mighty tentacles to bring all of humanity to heel? Or will she at least learn how to properly wait tables?
