My Modern Dungeon Life Continues as an Open World in Another World

Synopsis

In a world where sprawling dungeons suddenly appeared, Naruhito Tooyama, a seasoned explorer driven by ambition, met his end within their depths. Instead of oblivion, he awakens in a vibrant, open-world-like realm, burdened by a slave status and facing monstrous threats. Gifted with the unique "Fogblade" ability and his honed skills, he defies his grim fate. He earns the recognition of Aris, a powerful dragon, but rejects her proposal, determined to forge his own path. Can he truly break free from the predetermined destiny laid out before him and carve out a life dictated by his own desires, or will the shadows of the dungeon continue to haunt him in this new reality?
