In a world where power is everything, Kai is nothing more than a Zero Rank hunter, the weakest of the weak. His abilities are nonexistent, and he barely survives the daily grind of dungeons and monsters. For years, he's been forced to live in the shadows of stronger hunters, dismissed, ignored, and barely scraping by.
But when a mysterious event triggers an unforeseen Resonance within him, everything changes.
The Zero Rank Kai once wore as a badge of shame becomes the key to unlocking an unknown power, one that could alter the fate of the world. As monsters grow fiercer and the dungeons become more dangerous, Kai's newfound strength begins to rise. With every battle, every dungeon, every life-or-death moment, his abilities grow beyond anything the world has seen.
But power doesn't come without its price. As Kai's strength increases, so do the enemies that seek to destroy him - both human and monster. In a world where the strongest rule, can someone with a Zero Rank truly survive? Or will the system that has defined him all his life break him?
The Zero Rank is a story of survival, revenge, and the relentless drive to rise above it all. Join Kai as he steps into a battle for survival where only the strong will endure.
