When the world of Elarion is invaded by dimensional rifts, the ancient World System activates its long-awaited salvation protocol—summoning the “Chosen Hero” destined to save humanity.
But something glitches.

Instead of selecting the kingdom’s strongest knight or prophesied saint, the System locks onto Kaizen Arclight—a low-ranked porter with average stats, zero combat talent, and a habit of being in the wrong place at the wrong time.

[Fallback Candidate Assigned: Kaizen Arclight]

Branded as the prophesied savior, Kaizen is thrown into royal politics, elite academies, and deadly dungeon raids—while the real chosen hero rises elsewhere with overwhelming power and public adoration.

Unlike the flawless champion the world expected, Kaizen’s System is unstable. It grants bizarre skills, unpredictable evolutions, and “adaptive growth” that only activates under extreme humiliation, near-death experiences, or impossible odds.

While kingdoms mock him and nobles question the prophecy, Kaizen begins uncovering a terrifying truth: the System didn’t choose the wrong hero by mistake.
It chose the only one capable of breaking it.

As monsters evolve beyond prediction and the true hero’s rise begins to feel suspiciously scripted, Kaizen must decide - 
Will he live as the System’s backup file…

Or become the bug that rewrites the entire world?
Because sometimes,

the wrong hero is the one the world actually needs.
