The man who once chased the light to save people no longer exists.
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.
As the Calamity Gate opened, a massive monster legion ranging from S-rank to SS-rank poured endlessly from beyond the rift.

Undead armies, demonic hosts, giants, and dragons—disasters capable of destroying a nation—pushed into reality simultaneously, and the world turned into a battlefield in an instant.
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 hit instead.
The heart was pierced, and vital signs ceased completely. Seo Dokyeom lost his most precious comrade right before his eyes.
Though the Calamity Gate was eventually closed, the hero could not smile. From that day on, Seo Dokyeom lost all his convictions.
The man once called a hero turned his back on the world, becoming an entity that pursued 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.
However, 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 was over.
But at the moment everyone thought was the end, the dead hero opens their eyes once more.

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 strove 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 had vanished, and all that remained was the absolute boss of Oblivion.
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, replaced by a cold man who hunts only calamities.
They didn't know that he still keeps 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 he still...
If only I could see you one more time.
Hasn't been able to let go of that single wish.

Meanwhile.
In the deep, endless darkness.
A space where the heart had stopped, consciousness had faded, and even time had 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, enveloping the heart and spreading through the veins to the entire 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 that enveloped the body slowly dispersed, and no trace of death remained anywhere.
