The Harem System Belongs to the Villain

Kaizen was betrayed by the people he trusted the most. His best friend and his wife made sure he witnessed their affair before killing him, laughing as they revealed that all his friends had conspired against him. Filled with hatred and despair, he died, only for an ancient artifact to activate and transfer his soul into another world. He awakens in the body of a suicidal young noble from a fallen aristocratic family, a nobody mocked by society. Given a second chance, Kaizen swears revenge on everyone who betrayed him in his previous life. But then a strange system message appears in his mind: [Mission: Become the Demon King of Lust] To gain power, Kaizen must expand his influence, dominate powerful women, and build a legendary harem. From noble ladies and warrior princesses to demon queens, elves, and mysterious older enchantresses, the world is filled with targets waiting to be claimed. With his cunning mind and ruthless heart, Kaizen will rise from a disgraced noble to a feared Demon King, conquering kingdoms and hunting down his betrayers one by one. This time, he will be the one who controls everyone’s fate.
