[Justice delayed is justice denial!]
Kai a regular detective was killed by his partner after he uncovered the case he had been following for years now.
Dying with hate in his heart, Kai thought all was over for him, but something sudden appeared in his eyes.
[Host has awakened the Nemesis]
[Host has become the vessel of Nemesis]
[Become the man who sets the world back in order!]
In a world were massive crimes were happening 
in broad daylight,  christmas day, and even  new years. One man would rise to become a god.

Crazy Detective: I Have The System To Change The World.

Seeing the system message Kai wasted no time as he began with the tasks, he knew he doesn't have any time to waste.

Kai pushed himself off the floor, his arms trembling slightly from the last set of push-ups. The faint glow of dawn filtered through the small window in his room, but he didn't stop. Sweat dripped from his forehead, pooling on the wooden floor beneath him. His breath was steady, controlled. The system's demands were brutal this time again, but Kai embraced them without question. Each movement was a step closer to being prepared for whatever lay ahead.

By the time he finished the push-ups, the first rays of sunlight had fully illuminated the room. Kai sat back, wiping the sweat from his brow.

"Whatever the mission is," he murmured to himself, his voice low but resolute, "I'll be ready and make sure it comes fast."
