In a world where everyone is granted a powerful skill upon reaching level 50, Shun finally crosses the threshold— only to receive the worst possible ability:

《Level Down》.

The more he fights, the more his level drops. All the training, all his effort—undone in an instant. As his strength crumbles, he’s even nearly killed by a weak monster.

But just as he’s on the verge of death, Shun lands one final blow— and his level drops below zero.

That’s when everything changes.

Crossing into the negative level range, Shun unlocks access to a mysterious force:

“The Power Behind the World”.

He discovers that in this world, levels are actually a curse, and by breaking free from the system’s chains, he has awakened to an existence that transcends the rules entirely.

Now, with powers outside the world’s design, Shun becomes the ultimate anomaly— and its greatest threat.
