Renge, who is about to start first grade, goes with the others to check out the school before the entrance ceremony, before seeing Hikage off as she goes to Tokyo. The next day, as Renge and the others enjoy the entrance ceremony and begin their first lessons, Hotaru starts moving in.

A few days after transferring in, Hotaru and the others play a game in which they try to knock each other’s rulers off a table. Later, Hotaru gets lost while walking her dog Pechi, but manages to get pointed back towards home thanks to Pechi’s scent. Afterwards, Hotaru goes with Komari to watch the stars together, but run into trouble when their flashlight runs out of battery before they head back. Thanks to a wayward bottle cap Komari dropped, they soon manage to make their way back home.

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…

When Renge receives a bike from her grandma, she’s eager to practice so she can ride everywhere with her friends. But the rainy season is in full swing, so she sets about making a teru-teru bouzu in hopes that the rain will stop. Meanwhile, Renge is on duty to take care of the tadpole shrimp she caught while playing in a field, and she grows very fond of them.

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”…

As everyone is cleaning up the school on the last day of the semester, Natsumi and Hotaru end up weeding and watering the garden together. Natsumi realizes she’s never been alone with Hotaru before and tries to come up with things to talk about… Then summer vacation begins and the kids start to work on their summer homework, but quickly grow bored. Hotaru then tells everyone her parents are going to buy some fireworks…

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.

The second semester has begun, and the Asahigaoka students are making wood crafts in class. Renge and Natsumi pair up to make something together, but can’t come up with any ideas. Just when Natsumi starts to panic, Renge demonstrates her unique sensibilities again. Then at lunchtime, the smell of curry fills the air, and the Koshigaya sisters recall a tragedy that befell the school long ago…

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…

Renge goes to visit Natsumi, but she and her family aren’t home. She’s about to give up and leave when a hand starts talking to her from the other side of the fence! She thinks it’s a monster, and is relieved to learn that it’s the next door neighbor Konomi. But Konomi then tells her that she is, in fact, a monster… Later, the Koshigaya sisters tell Renge they were in first grade when they took off their training wheels, so Renge starts to practice riding her bike without the training wheels.

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.

During spring break, Renge and Hotaru head to school to feed the rabbits and end up finding Renge’s Legendary Sword.

It’s another idyllic day in the countryside, but things are anything but ordinary when Renge meets Akane, a flutist who has trouble playing in front of other people.

Sometimes it’s hard to believe Hotaru is still in elementary school! But even Hotaru needs to act like a kid now and then… or at least that’s what Konomi thinks.

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.

Ren pays Candy Store a visit to spend her New Year’s allowance, but her purchase puts Candy Store in an awkward position — one Natsumi finds absolutely HILARIOUS.

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.

It’s time to go camping! Ren’s heart and mind are prepared, but a nighttime stroll through the woods will put her willpower to the test.

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

Akane and Konomi go shopping, and they take a detour to play some festival games! But beginner’s luck will only get you so far, and there’s something weighing on Akane’s mind…

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.

New Year’s is here, and that means New Year’s money! What will everyone spend their cash on? And is there a way to get even more? Or perhaps that’s not a good idea…

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…
