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.

Frank sat at his desk, completely confused about what was happening in the classroom.


Everywhere he listened, he heard whispers.


"Looks like I'm safe from the government's investigation."


Love could be a far more dangerous attack than any government operation.


It was an attack capable of bringing even the strongest person to their knees.


She was sitting quietly, her heart beating faster than usual.


Frank, however, had no interest in any of that.


All he wanted was a normal school life where he could gain enough knowledge to survive this world.


Frank: "Sir, may I go to the bathroom?"


He simply couldn't endure all the whispers surrounding him.


Girl: "Is he really worth forming an alliance with the boys over?"


But he was undeniably the boy with the most admirers.


"What makes you think he isn't worth it?"


"If he isn't your type, then that's fine."


"I guess that just means less competition."


"I've just never felt that kind of spark."


Teacher: "If I catch either of you whispering again..."


"You'll run ten laps around the campus."


Frank stood alone in front of the bathroom mirror.


"Father entrusted me with an important mission."


"I can't afford to lose because of... love."


A second later, he immediately rejected the idea.


"Imagine asking a girl how to deal with girls."


He left the bathroom and quietly returned to his seat.


A small group of girls gathered together.


Girl 1: "I think I'm going to confess to him."


"First we need to make sure Mary isn't in our way."


Frank looked across the school grounds.


A determined expression appeared on his face.
