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, Hinata and Kokona eat crepes together and talk about the past. On the way home, Hinata really embarrasses Aoi. Later, Hinata tries to make up with her but only makes things worse. In the end, Hinata has to think of a way to truly apologize to Aoi.

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.

The girls continue their climb up Mt. Mitsutouge and discover plenty of interesting things. The climb gets more difficult, but Kaede shares some wisdom with Aoi. After a difficult part, Hinata is finally able to surprise Aoi with a beautiful view of Mt. Fuji!

Aoi and Hinata have a camping cook-off.

The girls reach the summit of Mt. Mitsutouge and Aoi realizes something about herself. After eating lunch together, they begin their descent. It's a difficult descent, but a reward awaits them at the bottom!

Aoi meets a girl from her school who is crazy about backpacking.

Hinata, Kaede and Kokona meet to discuss secret plans to surprise Aoi with a special view of Mt. Fuji, and decide on climbing Mt. Mitsutouge together. They meet up with Aoi and begin the climb, but they are steadfast in keeping the surprise a secret from her until the top!

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

With the help of Hinata's dad, the girls familiarize themselves with the necessary gear to climb.

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

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

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

Aoi spends most of her time alone, but an old friend from middle school has arrived to make good on an old promise.

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

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

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

Aoi meets with Hinata and her father and gets motivated to climb Mt. Fuji. Aoi begins preparations, but her mom is not okay with the idea of climbing the mountain at night. She learns to stand up for herself and pursue something she really wants.

Hearing about "mountain coffee" from Hinata's father, Aoi, feeling provoked by Hinata, becomes determined to try it as well, despite finding coffee bitter in general. After getting some advice from Kaede and Yuka, Aoi goes with Hinata to the Kanhasshu Observation Platform, where she puts her coffee making into practise.

Aoi makes plans to go to Gunma with Honoka while Hinata, unable to get in touch with Aoi, ends up making plans to go to Mt. Akagi with Kokona on the same day.

Mt. Fuji awaits! What will Aoi and her friends see from that legendary summit? The peak is in reach... but will they all make it to the top?

Their next thrilling summit isn’t a mountain. It’s the king of the coasters, and they’re going to conquer this peak, too!

The mountaineering club is a lot of fun, but not everyone was into the idea at first glance. Some people need a more comprehensive introduction!

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…

Aoi makes the plan for climbing Mt. Fuji. She buys snacks and drinks for the climb the next day. Even though she is prepared, she still feels uneasy. Finally, the big day arrives and the girls make their way to Mt. Fuji.

On the day before the Tanigawa climb, Kokona, whose birthday is on the same day, gets some new shoes as an early present from her mother and decides to go on a walk to Akebano Children's Forest Park to try them out. After returning home, Kokona celebrates her birthday with her mother, who ran a little late home from work. Meanwhile, Aoi, who spent the day making a pound cake, wonders about what will happen after her dream is fulfilled.

The day of the Mount Tanigawa climb finally arrives, with Hinata also pondering what will happen after she and Aoi fulfil their dream. After a series of staircases and some obligatory forms, the girls arrive at Tanigawa, where Aoi must face the cable car first hand. Despite Aoi still being afraid, the other girls help her get through it before Hinata helps her ride a ski lift.

As the girls officially start climbing up the mountain, they encounter a quiet young photographer named Honoka, who had previously helped them by the cable car. Interested in her, Aoi decides to follow Honoka as she goes about her photography. After encountering some rainfall, the girls arrive at the mountain hut, where Aoi and Hinata look back on memories of their previous time there, worrying what happens after their promise is fulfilled.

Finding that she won't be able to take on Mt. Fuji again until next summer, Aoi goes with Hinata and Kaede to look at some hiking shoes. Initially sceptical of their price and heaviness, Aoi finds some shoes she likes and climbs up Mt. Tenran to break them in.

Aoi decides to tackle the Hanno Alps, inevitably finding the experience pretty tough by herself. She is soon joined by Kokona, who accompanies her to Nenogongen to look at the shrines.

Aoi is approached by her classmate Mio and invites her and Hinata to karaoke out alongside her friends Kasumi and Yuri. As Aoi worries about what to sing, Hinata encourages her not to overthink things and become more confident around everyone.

The girls have Honoka join them for dinner, where they celebrate Kokona's birthday together. Later that night, Honoka gives some advice to Aoi concerning her promise, and the two exchange contact info with her. The next morning, as the girls continue their ascent, Aoi and Hinata look back on their recent adventures as they finally watch the sunrise together, realising that their promise will continue forever as they keep making memories together.

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.

Aoi, Hinata, Kokona, and Honoka go to Lockheart Castle in Gunma, each bringing their own unique cameras to take pictures of everything.
