Starting out as a Dragon Slave Novel

Isaac awakens not to peace, but to a nightmare world identical to his own, where monster-filled portals threaten apocalypse within three days. Only enlightened hunters ranked F to SS can stop them, and Isaac is the lowest tier—an orphan destined to struggle in the shadows. Everything shifts when his spirit is violently torn into another realm, a hellscape where dragons enslave humanity. Tortured and shattered, Isaac realizes this world isn't mere nightmare—it's a warning of what's to come. Amid the chaos, a mysterious system grants him an impossible gift: the ability to absorb the power of every monster he kills. Once powerless, now transformed, Isaac gains strength with each victory. Armed with his katana and harboring a burning secret, he refuses victimhood. To survive both realities and prevent catastrophe, Isaac must uncover the connection between these worlds and evolve into the ultimate hunter before it's too late.
