“70 years of misfortune—time to pay up, world!”

In a world where dungeons appeared decades ago,
Yukito Takahashi was the lowest of the low—
a G-rank adventurer burdened with a tragic flaw:

Even at Level 99, his stats never increased.

Laughed at. Shunned. Forgotten.
He lived a life of failure and poverty, dying alone as an old man—
without ever seeing the fruits of his relentless effort.

But the moment death came…

[A fatal error in your Status System has been detected.]
[Applying patch. Rolling back your life…]
[Hidden parameter unlocked: Luck +9999]

And just like that—Yukito opens his eyes again at age 15,
the day he first registered as an adventurer.

At first, nothing seems to have changed…
Until he notices one thing:

His Luck stat is maxed out. 9999.

And now?

Guaranteed rare drops from monsters

Critical successes in skills and item enhancement

Unmissable attacks, even with clumsy weapons

And the chance to finally protect his loved ones

Armed with a lifetime of regret and unlimited luck,
Yukito sets out to change everything—
and this time, the world is on his side.
