May 20, 2030.
An unknown figure stands atop the tallest building on Earth — and the age of hidden fear begins.
Beneath the fragile surface of reality, gods and indifferent higher entities rule through an invisible judgment system that mortals were never meant to witness. Ancient clans that once kept the balance have been hunted to extinction. In their wake, a secretive government organization gathers the shattered survivors of the supernatural — branding them Sinners.
They are not saviors. They are not monsters.
They are living proof that even divine judgment can break.
Rookie Sinner Karry steps into this shadowed world alongside the ice-veined operative Sasha and the eerily composed Arnold — a man whose calm hides depths no one dares question. Their first mission is simple: rescue hostages from a routine threat.
It ends in catastrophe.
Breaches tear open between realms. Cities vanish without trace. Entities from above descend like hunters, while governments below scramble to erase every witness. As the veil rips wider, Karry uncovers the chilling truth:
The gods are not protecting humanity.
They are evaluating it.
And walking silently through the growing storm is Arnold — a figure who understands the rules of existence better than any god, fears nothing, and draws his blade only when the line between survival and annihilation is crossed.
Because when the final judgment descends…
it will not arrive as war.
It will arrive as calamity.

After school, Frank walked through the quiet streets.


This time, however, he had learned the basics of sensing. As he walked, he carefully checked his surroundings to make sure no one was following him.


Soon, he spotted a beggar sitting in a narrow alley.


Frank: "What comes after three cups of coffee?"


The beggar answered without hesitation.


Beggar: "Then where's the coin for a coffee?"


Frank reached into his pocket and pulled out a shiny coin. At first glance, it looked exactly like an ordinary Ritna coin.


The moment the beggar touched it, the coin changed.


Its silver surface darkened into a mysterious blood-red color.


At its center was the unmistakable symbol of the Phoenix Empire.


The beggar examined it for a moment before nodding.


Beggar: "A true coin... First time here?"


The beggar pointed toward what looked like a solid stone wall.


Beggar: "Go in. And whatever you do... don't get trapped in the underground."


He glanced around the alley, making sure no one else was watching.


His body passed straight through as if the wall didn't exist.


Before Frank completely disappeared, the beggar called out one last warning.


Beggar: "Use the elevator. Don't trust any navigator. Most of them are scammers."


Beggar: "And remember... that single coin is worth more than a large estate."


Beyond the wall, countless doors stretched in every direction.


At the center stood an enormous elevator.


As the elevator descended deeper and deeper, the familiar feeling of the surface gradually disappeared.


An enormous underground city appeared before him.


Golden lights illuminated countless buildings.


Even the ceiling held roads and structures, making it seem as though an entire city had been built upside down.


A calm mechanical voice echoed throughout the elevator.
