He becomes the last bastion of hope for mankind. However, one of his mistakes gives rise to a calamity far worse than the Demon King.This calamity is conceived in a dungeon, abandoned as a fetus by its mother, and raised by the Demon King himself.

In the dungeons?He becomes Zero, an anonymous hunter operating outside the system, clearing high-tier raids solo, and slowly building a legend no one can trace.The world thinks he’s a joke.He’s about to become its biggest problem.
