Kami Skill "Kokyuu" Suru dake de Level Up Suru Boku wa, Kamigami no Dungeon e Idomu.

In a kingdom where every citizen receives a unique skill from the queen upon turning fifteen, Lana eagerly anticipates the ability that will shape his future. When his long-awaited skill is revealed to be "Breathing"—a seemingly mundane power that appears to do nothing more than its name suggests—Lana faces a difficult choice between abandoning his dreams or pursuing them against all odds. Despite the apparent uselessness of his gift, Lana refuses to let it define his limits. Armed with determination and an unyielding spirit, he sets out to prove that one's worth isn't measured by the power they're given, but by how they choose to use it. His journey into the mysterious dungeon system will test not just his abilities, but his resolve to forge his own path in a world where skills determine destiny.
