The world is falling apart.

Rifts tear open across cities, monsters pour into reality, and entire nations begin to collapse under the weight of chaos.

Min Cheol-woo, a former pro gamer turned contractor for GeumMyeong Security, is thrown into the heart of it all. After exposure to a mysterious “blue drug,” he gains abilities far beyond human limits—but power comes at a cost.

From the collapsing streets of Hong Kong to the battle-scarred zones of Australia, he fights against everything this new world throws at him—corporate mercenaries, parasitic entities, and monstrous creatures born from the gates.

Survival isn’t just about strength.

It’s about who you trust.

Forming a fragile, makeshift family with his sister Yuri—a deadly exosuit swordswoman—and Yulia, a gifted girl with radar-like abilities, Cheol-woo carves out a place in a world that no longer has rules.

But the deeper he goes, the clearer the truth becomes:

This catastrophe isn’t random.

From human-robot hybrids to global conspiracies and covert military operations, something far bigger is unfolding behind the scenes.

And in a world where humanity itself is being rewritten…

Pulling the trigger might be the only way to stay alive.
