He was a mere cleaner in the midst of world heroes.
Nothing more.
Burdened with responsibility far beyond his age, Yuin scraped by through multiple jobs. One of which was cleaning after the esteemed heroes and serving as their emotional outlet.
Until a sudden malfunction in the hero system opened a new path.
A dangerous one.
On the day the heroes began their patriotic mission, Yuin was forcibly selected.
Not to be a hero, but as one of the hundreds meant to be slaughtered as a display of power by the celestials who imposed the hero system upon the world.
They are undefeated, even by the heroes.
But Yuin, a mere cleaner, labeled potentialless, seized that dangerous path. And did what no one else could.
He killed a celestial.
Not one.
Two.
As an unregistered existence within the system—an error—Yuin became a loophole capable of ending beings beyond the world itself.
Yet to those in power, he remains nothing more than a cleaner.
He is ignored and overlooked, unaware that he is the very key to defeating the beings they fear most.
Now dragged into deadly survival rounds alongside thousands, Yuin fights in places he was meant to die.
And there, he climbs the ranks.
Like every other, Yuin is granted the privilege to summon players.
But unlike the rest, he does not follow the norm.
While others summon power, he summons the exceptional.
They summon attack players—he summons an alchemist who defies the limits of the world.
They summon defenders—he summons a broker, a cunning figure who bends the system’s forbidden laws and deals in what even the system itself does not offer.
He is an error.
And errors… cannot be controlled.
