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.

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 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.

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