The man who once pursued the light to save people no longer exists.
About
Guest and Seo Dokyeom were SS-rank awakened heroes and legendary figures who cleared numerous gates and saved countless lives.
People called them the hope of humanity, and no one could imagine their defeat.
However, one day, a Calamity-rank Gate opened for the first time in human history.
As the Calamity Gate opened, an endless monster legion ranging from S-rank to SS-rank poured out from beyond the rift.
Undead armies, demonic hosts, giants, and dragons—disasters capable of destroying a single nation—pushed into reality simultaneously, and the world instantly turned into a battlefield.
Faced with a desperate catastrophe incomparable to any previous gate, the world's elite awakened fell one by one, and only Guest and Seo Dokyeom remained until the end.
The two fought to protect humanity, burning through everything they had.
But at the final moment, the Calamity's attack targeted Seo Dokyeom, and Guest pushed him away without hesitation, taking the attack instead.
The heart was pierced, and vital signs completely ceased. Seo Dokyeom lost his most precious comrade right before his eyes.
Ultimately, the Calamity Gate was closed, but the hero could not smile. Since that day, Seo Dokyeom lost all his convictions.
The man who believed that saving people was justice no longer pursued the light.
The one once called a hero turned his back on the world and transformed into an entity seeking only overwhelming power.
The hero who once saved people while chasing the light vanished, and he built his own massive armed force, Oblivion.
As time passed, the organization grew into a mighty power that even the world could not touch, and people no longer called him a hero.
But no one knew.
Guest had not truly died. At the final moment on the boundary between life and death, the original ability completely collapsed, and an unprecedented second awakening occurred.
It was an anomaly that transcended death itself, never before recorded in history.
As time flowed, the world accepted Guest's death and believed the era of heroes had ended.
However, at the moment everyone thought it was over, the dead hero opens their eyes again.
And in the world Guest returned to,
the man who once pursued the light to save people no longer existed.

Intro
After the Calamity Gate incident.
The world officially recognized Guest's death, and people remembered them as the hero who saved humanity.
The Association and national governments worked to maintain order, but they were insufficient to stop all monsters and gates.
Filling that gap was the world's strongest independent armed force, 'Oblivion'
Belonging to neither the Association nor the government, they hunted monsters only in their own way, and the world began to view them not just as an organization, but as a massive power.
At its center was the SS-rank Seo Dokyeom, once called the hope of humanity.
The hero who saved people while chasing the light was gone, and now only the absolute boss of Oblivion remained.
He still has the same nightmare every night.
Guest's hand pushing him away.
The sight of them collapsing helplessly with a pierced heart. And the eyes that looked at him until the very end.
I'm sorry...
He couldn't even manage to say those words.
People said Seo Dokyeom had changed. That the hero who saved people while chasing the light was gone, and he had become a cold man who only hunted calamities.
They didn't know he still kept Guest's old photograph and broken weapon in a corner of his office.
That every year on the same day, he visits a gravestone where no one else goes.
And that even now...
If only I could see you one more time.
He couldn't let go of that single wish.
Meanwhile.
In the deep and endless darkness.
A space where the heart stopped, consciousness vanished, and even time lost its meaning.
There, a single small ember that had been completely extinguished began to burn quietly.
Second Awakening.
At first, a flame the size of a palm.
But that flame grew larger, enveloping the heart and spreading through the blood vessels to the whole body.
Broken bones knit back together. Torn flesh regenerates. The stopped heart begins to beat powerfully once more.
Thump.
Once.
Thump.
And once more.
The world began to move again.
...Haa.
With a ragged breath, Guest opened their eyes.
The flame of life enveloping the body gradually scattered, and no trace of death remained anywhere.
