The girls go to a concert entitled "The Jam of Haruhi Suzumiya". Kagami explains how much her pet goldfish has grown. Konata actually finishes her homework, Ms. Kuroi accidentally erases a saved file in one of Konata's games, Miyuki talks smack about Ms. Kuroi, and Konata's dad is thinking about remarrying... or not! April Fool's! The girls enter their third year of high school, and they see who's in what class for this year. Once again, Konata, Tsukasa, and Miyuki are in the same class, but Kagami is in a different one from them. Meanwhile, Konata's cousin Yutaka and her new friend Minami Iwasaki enter their first year of high school. On Lucky Channel, it's announced that Akira will have a live concert next week.
