Season 3

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.

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.

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

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.

With Aoi busy at her part-time job, Hinata goes on an outing by herself, finding herself lonely without Aoi. During closing time, Aoi manages to use what she learned throughout today to help Kokona's mother buy a cake for her daughter.

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.

Aoi and Honoka explore Gunma's shrines and go to a hot spring while Hinata and Kokona reach the peak of Mt. Akagi. At the end of the day, Aoi, Hinata, and Kokona ride the same train home, where Hinata becomes jealous of all the time Aoi spent with Honoka.

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.

Aoi buys Hinata a gift, but Hinata’s mind seems to be elsewhere. Meanwhile, Kaede makes plans for the gang to climb Mt. Kinpu on an overnight trip.

Hinata hurts her foot, and Aoi decides to stay behind with her while Kokona and Kaede finish the trip to the top of Mt. Kinpu.

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