Chiyo-chan's Day / High School Friends / Lunch / Afternoon / Skipping Rope.Chiyo wakes up, fixes her lunch, wakes her parents, eats her breakfast, and then leaves for school. Chiyo learns from former elementary school classmates, Miruchi and Yuka-chan that jump rope is becoming popular again. Sakaki walks with Chiyo but disappears when she sees Kamineko. Tomo purposefully forgets to record a show for Yomi. Tomo, speculating on why Yukari is late, guesses that Yukari is trying to buy the limited edition box of a video game. A bandaged Sakaki enters the classroom after trying to pet Kamineko, and a tardy Yukari arrives only to prove Tomo's theory right. Osaka falls asleep in class, and Yukari catches her. Kimura breaks down when revealing that girls at another school sometimes attend homeroom in gym clothes or swimsuits. Chiyo, Tomo, Yomi, and Osaka eat lunch on the roof, enjoying the breeze of the clear sky. Chiyo tries swimming in gym class without a kickboard, but Tomo accidentally runs over her with one. Tomo does a terrible job of sweeping, and Osaka is unable to use a dustpan correctly. Chiyo does her homework after school. Chiyo is accompanied by Sakaki when walking Mr. Tadakichi through the park, eventually witnessing some children jumping rope in the park. The children leave the jump rope behind when they all depart, letting the three spend time jumping rope. They are soon joined with Tomo, Yomi, and Osaka. Chiyo prepares to sleep in the late evening, only to hope to stay up all night when she is older. Yomi reads at her desk, Tomo eats snacks while watching a funny television show, Osaka relaxes in the bathtub, Kagura plays a video game, and Sakaki reads on her bed with plush cats surrounding her.
