Just when I thought I was reborn and returned to the police academy to make up for the regrets of my previous life, I accidentally activated the [Killing System], my hands were stained with blood, and I embarked on a dark road of no return in which killing is exchanged for strength and crimes are punished.
Just when I thought I could just settle my grudges and use this taboo power to wipe out the monsters in the city, I discovered that the sacrifice in my previous life was no accident. There was a shocking secret hidden behind it that could subvert my understanding, and it involved unimaginable high-level shady stories.
When I thought that wandering between black and white, establishing my own underground order, and becoming the uncrowned king of the city was the end, I discovered that this was just the beginning. The real enemy was far larger and more terrifying than I imagined. And everything I did might be pushing myself into the center of a bigger storm, or even... Repeating the mistakes of my previous life?
