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.

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.

Konata and her dad discuss Gun**m (Gundam).

Yutaka thinks that having an upperclassman like Konata is advantageous when she needs help with her school work, but Konata doesn't think so.

Konata complains about how baseball games ruin the TV schedules.

Konata and the girls discuss what qualifies as "moe".

Hiyori shows the hardships of being a manga artist.

Yutaka asks Hiyori about the meaning of "yaoi".

On Lucky Channel, Shiraishi expresses how much he loves the outdoors. So Akira suggests that he go through the forest of Mount Fuji and get some water for her.

It's almost time for the school's culture festival. While the girls are preparing for their classes' themes for the festival, Patricia proposes that she and the girls in her class should do a cheerleading act for the opening ceremony of the festival. Patricia "persuades" Konata into performing the routine with her, who in turn gets Kagami, Tsukasa, Miyuki, Misao, and Ayano to do it as well.

Akira Kogami finally makes an appearance on the actual show, although she and Shiraishi are still on bad terms.

Before the opening ceremony, the girls practice the cheerleading act one last time to the song, "Motteke! Sailor Fuku!"
