“Delicious Day” “Oishii Hi” (おいしい日)

The Japanese New Year is coming up and everyone is excited. Kagami, however, is once again worrying about her weight having increased again. She spills the fact that she likes eating mochi and Konata jokes that gorging on it has caused Kagami’s weight gain. Miyuki explains that eating a rice cake that is as big as a matchbox is the same as eating a whole bowl of rice. The girls discuss various traditions, foods, and myths about New Year’s, and which ones they actually practice. Valentine’s Day also approaches, and the girls find themselves only sharing chocolates between themselves, as they don’t have any boys to give them to. The girls also talk at length about kotatsu. Later, at a cafe, Konata announces that her younger cousin, Yutaka Kobayakawa, will be coming to live with her. Konata goes to the anime shop again where the dynamic comic book characters (led by returning character Meito Anizawa) yet again try and make a sale from her but fail, ultimately because she was 3 yen short of the price of the DVD they were about to sell her.

“Let’s Go to the Festival” “O-matsuri e Ikō” (お祭りへ行こう)

Konata, Kagami, and Tsukasa go to Comiket 71, at the end of 2006.

Meanwhile, it appears that Akira Kogami makes an appearance, as declared in the previous episode’s Lucky Channel. However, it turns out to be just a cardboard cut-out of her with a message stating that Akira cannot attend because of sudden illness. After the morning trip around Comiket, Konata meets Tsukasa and Kagami at a New Year festival and receives very bad luck in a lottery drawing. At home, Konata goes out of her way to be nice to her dad in order to receive her otoshidama. She logs into her game to wish others a happy new year only to once again encounter her teacher online.

They get on the topic of how sometimes when they get sleepy on a bus, they sometimes tend to lean on the person next to them. Whenever Konata gets on her bus, she gets sleepy and falls asleep a few times on the shoulder of the person next to her. She realizes that she got off the stop before, but whenever she tries to go back to her seat, someone took it and Konata is forced to stand up.

Konata and the Hiiragi twins are on a bus and Kagami talks about how there has been frequent junk mail lately and Konata explains that she uses an address that is hard to guess.
