Aoi Yukimura, a shy and indoorsy high school girl, has always preferred the comfort of her room, haunted by a childhood fear of heights. Her quiet life is upended when she reunites with Hinata Kuraue, her energetic and adventurous childhood friend, who drags her into the world of mountain climbing. Starting with small hikes, Aoi rediscovers the joy of nature and the thrill of reaching new summits, joined by Kaede Saitou, a seasoned climber, and Kokona Aoba, a cheerful beginner.

Arel is born to two legendary heroes in a world where classes grant skills. When he is found to be classless, others believe he can never receive skills from the goddess. He discovers that he can learn abilities by watching others use them enough times. He can also adapt and improve what he learns. The beginning follows his rise through effort despite a system that labels him talentless.
