Everything is normal as the four main characters attend a normal day of high school. They discuss different foods and how they eat them. Later on, Kagami gets sick and all the characters go over to make sure she is okay.

Throughout Golden Week, Tsukasa and Kagami have been playing together. However, Tsukasa does not know that her sister has actually been waking up earlier and going to bed later than her in order to study and finish homework. After the break, Konata does an all-nighter and manages to obtain an above-average score despite doing no studying during the short vacation. Later, Konata decides to get a job at a cosplay café in order to fund her otaku desires.

It is summertime for the girls; that means one thing: comfortable summer uniforms! Tsukasa and Kagami are fraternal twins, but Konata shows them the similar and different characteristics they share. Konata, Kagami, and Tsukasa each try to put their hair into a ponytail, just to see who looks best. Unfortunately, Kagami is the only one who cannot pull it off.

Summer is almost here, and Konata is still staying up late playing online video games, reading manga, and watching anime instead of studying. Kagami and Tsukasa's birthday arrives on July 7 and Konata and Miyuki celebrate with them. After this episode, the director is changed from Yutaka Yamamoto to Yasuhiro Takemoto.

Summer vacation has just begun. Konata, the Hiiragi twins and Miyuki go to a summer festival clothed in yukata. Yui Nanami is first introduced in this episode, currently on patrol at the festival. Konata and Nanako chat over an online game. Later on, Konata and the twins meet and do homework together. Back at her house, Konata finds a rare drop and celebrates it with her online friends.

The group, plus Cousin Yui and Nanako, go to the beach for some summer fun. After Yui races down the road, and Nanako gets really lost, they finally make it and spend a night in a Japanese inn. After a day at the beach, and Nanako becoming too drunk to drive, they go back to the inn for a shower and to spend another night. After arriving home, the twins have to clean their bedrooms, Konata discusses cleaning tactics with Kagami, and Miyuki is told she has to go see the dentist, or her mom is bringing the dentist to their house.

The gang comes back to school after the summer break and Konata is in a good mood because she has become hooked on Marimite. Miyuki is forced to go to school without her glasses because she broke them. Tsukasa recieves her first cell phone, but its life is very short after Tsukasa leaves it in the washing machine. On Lucky Channel, Shiraishi follows up on a fan's request for a certain hairstyle.

It's about that time of year for the girls: athletic festivals! Konata's father is excited because he has been dying for an opportunity to try out his new camera. Kagami is in an eating contest, Konata is in the one-hundred meter dash, Tsukasa has to jump over hurdles, and Miyuki is in a relay race, where she brings the team from third to win the race by using her physical assets at the end. Later, Tsukasa is trying to learn a song on the recorder. Unfortunately, she is not very good. She then is taught by her sister not to blow so hard into it. Later, we see the girls in at school in a lunch line having various conversations about food and public eating facilities.

It is time for tests! Unfortunately, Konata cannot seem to concentrate on studying and instead reverts to slacking off and playing games. She tries to ask Miyuki about good study habits, but in the end she does bad on her tests. Tsukasa got help from her sister and this time got better scores, but Kagami's scores were still higher despite her own scores going down somewhat. Later, Konata and the Hiiragi twins go to a cake café but end up taking too much and must finish it all or pay an extra price.
