Lediv's plea for help leads to a supernatural contract: For every person that he kills, his life extends by one month. To justify his actions, Lediv decides to target uncaught criminals worldwide. Yet working solo is lonely, so he vows to bring his best friend and intellectual rival Kiros along as a sidekick. Unknown to Lediv, Kiros is recruited by a secret detective agency. Kiros' first case?
