Hinata convinces Aoi to try climbing a mountain, but Aoi thinks they should start with a small mountain and work their way up to the big ones.

Aoi and Hinata have a camping cook-off.

It's Aoi's turn to pick the mountain, so she calls on her new friend to help.

Aoi picked the mountain but now she needs the right equipment.

Aoi and Hinata embark on their second climb and meet some interesting people along the way.

Hinata teaches Aoi, mountain manners and learns about giant flying squirrels.

Aoi, Hinata, and Kokona help each other down the mountain.

In preparation for their next trip, Aoi invites Kokona over to help her cook snacks.

Aoi, Hinata, Kaeda, and Kokona meet up for a picnic at Hannou River.

Aoi and Hinata put up a real tent in Hinata's yard! Afterwards, Kaede and Kokona join them and they cook a meal outside together. They camp in the tent overnight and get excited about climbing mountains soon.

You thought it was all about mountain climbing, but no! It's actually about swimming! So obviously you need to buy a swimsuit now.

On the day the Aoi invites Honoka to join her and the others for a fireworks festival, she and Hinata get into another argument with each other. As Aoi takes Honoka on a tour of Hanno, she can't stop thinking about Hinata and decides to try to make up with her, while Hinata hear how Aoi feels about her from Hikari and decides she should apologize too. Both have trouble finding an opportunity to apologize to each other during the festival, but soon find they don't really need to, quickly forgetting why they even fought in the first place.

Wanting to repay Hinata for the souvenir she got her from Mt. Fuji, Aoi invites her for a late night climb up Mt. Tsukuba to treat her to a night view at the top. Arriving at the top, Aoi resolves to once again take on Mt. Fuji.

Aoi’s classmates invite her to hang out at Ikebukuro. She knows Hinata has prior arrangements that day, so she hesitates, but decides to go anyway.

It’s November, and Hinata’s birthday is coming up. Aoi tries to choose a gift for her, but nothing seems right.

A trip to Naguri Lake? Sounds like fun, especially since Aoi gets to try canoeing with her coworker. But does this outing feel a bit…unusual?

Hinata, Kokona and Aoi plan to watch the first sunrise from atop Mt. Tenranzan, but the plan may change on a dime when they get unexpected news!

With Valentine’s Day approaching, Aoi and the girls invite Honoka out to hike Mt. Mitake in Okutama.

Learning to fish is fun… or at least it should be. So why does it feel like Kokona’s mind is miles away from the day’s activities at Naguri stream?

A spur-of-the-moment proposal snowballs into Aoi leading her entire class on a hike! Somehow this feels more like herding cats than a game of “follow the leader,” though…

After her last attempt, it’s time for Aoi to scale Mount Fuji once again. But she isn’t climbing alone, and her plans will need to make her friends happy, too.

The girls head up the Subashiri Trail despite fears about the weather, and things seem to go smoothly! But past is all too often prologue, and Hinata must make a big decision…
