Alexander Drake awakens in Orario after a Divine being grants him reincarnation into the Danmachi world, bestowing Hell's Forge as his extraordinary gift—though the cost is steep: all memory of his former existence. Armed with this legendary ability, he ventures into the perilous dungeons as a novice adventurer, forging his path through trials and battles in the dungeon city where gods and mortals collide. Hell's Forge becomes his greatest weapon, reshaping destiny with each flame and strike as he climbs from obscurity to become a force to be reckoned with among Orario's elite adventurers.
