While reminiscing about her journey so far, Aoi Yukimura finds herself eager to go mountaineering once more. A likely opportunity arises when Koharu Senjuin invites Aoi to check out the Mountaineering Club after school. As the head of the club, Koharu speaks enthusiastically of the activities she and the other members partake in, especially as they strive to reach the top in various competitions. Although impressed by the club's dedication to its goals, Aoi feels reluctant to join, preferring to learn and enjoy mountaineering at her own pace. Her experience during this brief visit, however, leaves her wondering why she climbs mountains in the first place. With the support of her friends, Aoi searches for the true motivation behind her hobby, all while continuing to train for the highly anticipated second trip to the summit of Mt. Fuji.
