Reincarnating to find two beauties laying on his lap, Jake found out that he was a Demon Baron with no bloodline. Exiled from the Hell to the human world, Jake was left with a small dungeon and his two servants with almost no monsters under him.

Just when he thought things weren't good for him, he suddenly heard a female voice in his head.

[Ding! Welcome host to The Sin System.]
[Please spin the Sinner's Roulette to unlock your first Sin.]

"This is..." As Jake instinctively touched the dark disk that came in his sight, the disk started spinning and stopped five seconds later. He heard the system's voice again.

[Ding! Congratulations, you have unlocked the Sin of Lust.]
