Han Seungwoo has learned the hard way that justice is for sale.

His family was murdered by a chaebol heir, and the people who should have punished the culprit helped bury the truth. With corrupt officials, powerful corporations, and other untouchable criminals running rampant, Seungwoo has little faith left in the system.

Then, on his twentieth birthday, everything changes.

A mysterious Awakening System chooses him as its sole Alpha Tester, granting him a unique trait: The Judge. With the ability to perceive and harness human karma, Seungwoo gains a way to punish those who have spent their lives escaping the consequences of their actions.

He doesn't intend to let them get away with it.

As he delivers his own brand of justice and gathers allies who still believe the innocent deserve protection, a far greater disaster draws closer.

The coming Cataclysm will change the world forever. And when the coming Cataclysm unleashes horrors humanity has never faced, the power he gained may be its best chance at survival.
