Aoi Yukimura

Aoi Yukimura serves as the central protagonist of the story. A childhood accident left her with a deep-seated fear of heights, steering her toward indoor hobbies as a coping mechanism. Everything changed when she reunited with her old friend Hinata upon entering high school — an encounter that led to her being somewhat reluctantly pulled into the world of mountain climbing. With each summit she conquers, Aoi gradually dismantles the psychological barriers holding her back, blossoming from a withdrawn loner into someone capable of forging genuine bonds with her fellow club members. Her journey is ultimately one of quiet courage and meaningful personal growth.
