It’s the day before Golden Week, and the students of Asahigaoka Branch School listen to the voice of their unmotivated teacher, Kazuho, as they take tests. Natsumi struggles the most with the tests, so the others help her study during the break. Then, during Golden Week, the students agree to do their holiday homework together, so Renge decides to do something about their lazy teacher before the others arrive…

One morning, Natsumi uses a toy fortune dispenser to read Komari’s fortune, and tells it her, “bad luck: beware of water.” Komari says she won’t be near any water that day anyway, but when they get to school, they’re told that they’ll be cleaning the school pool… The next day, the Koshigaya sisters are bored at home on a day off from school, so Natsumi reads Komari’s fortune again and draws yet another “bad luck”…

Hotaru is finally getting used to how kids play in the country, although she’s still afraid to jump off the bridge into the river. Hotaru returns home from playing to find a letter from her friend in Tokyo, with a photo of her old friends at an amusement park, making her feel nostalgic. Meanwhile, Hikage is home for a visit and shows off pictures of Tokyo Tower to Renge.

Natsumi’s mother asks Natsumi to go catch something to live in the family’s pond, and Natsumi agrees when she’s told she’ll be paid. She lends Natsumi a watch and tells her to be home by curfew, and all the kids go out for a day of fishing. Later, Konomi sees that Natsumi still doesn’t seem like a girl at all even now that she’s in middle school, and brings some of her old outfits over for her to try on…

One morning during winter break, Ichijo Hotaru and Koshigaya Komari are on a walk when they run into Fujimiya Konomi on her way back from practice. Komari takes great interest in Konomi’s cellphone.

After breaking a bonsai planter with a Surefire Kill Shot, Natsumi and Hikage practice the art of apology… sort of. Turns out neither one of them is very good at it.

Beep boop! Koma-plushie is live, boop beep! But Hotaru isn’t a master of robotics just yet, and her pet project still has a long way to go before it’s ready to fly.

Parents’ Day provides Natsumi a particular variety of anxiety, but she finds a way to relax when Renge brings home a new friend.

Komari receives an unexpected visitor. Now she’s making a weird face and can’t seem to knit properly. But don’t worry — Natsumi will cover for her. Sort of.

Once the kids are asleep, the adults get to partying! …wait, what’s that noise? Ren is awake!? Uh oh…

Following a graduation ceremony, Renge and friends spend the day playing in the great outdoors. It’s days like these you wish would never end…
