Description:

When one reached the age of 15, they were bestowed upon a skill by the Empress. Runner was a boy who dreamed of becoming an adventurer, and the skill he received was “Breathing”—an absurd skill that allows him to breathe in and out. Despite his disappointment, he was determined to dive into the dungeon accompanied by his childhood friend Prine so as to save his sister who was cursed into an eternal sleep by a witch. Unbeknownst to him, his skill was actually the godly “Divine Breathing”… Aim for the depths of the dungeon with the ultimate skill! Source: Futabasha
