Metanoia

The Lower Sector, formally the United States, is infested with organized crime in the year 2044.

Arkin is a war orphan, who escaped from across the seas when he was merely a teenager years ago and found his place as a gunman for various companies, while N works for a branch of the black market, dealing with the supply of organs to clients.

Two sides of the same coin. Killers. Cold blooded. Maybe even too far gone.
But if that were true, can monsters dream of salvation, like they do?
