He was on his way to buy some beer to celebrate his acceptance as a civil servant when he was suddenly isekai’d by truck-kun.

[WARNING: MATURE CONTENT R18][SMUTS]Rex Rexilion was a scumbag piece of shit—and he knew it.He was a bully. A serial heartbreaker. A man who laughed at consequences and crushed others for fun.When death finally claimed him, Rex expected hell. Instead, he woke up in another world.A cruel, lawless fantasy realm where heroes are hypocrites, gods are bored, and morality is just another currency.Before Rex could even process his reincarnation, a sarcastic system appeared before his eyes with a mocking, smug, and disturbingly honest personality.[Desire Authority System Activated.][Objective: Harvest desire from all womens you can get.]The rules were simple and ridiculous: the deeper the desire of MILFs, GILFs, queens, widows, and forgotten legends, the stronger Rex would become.All of his strength, skills, titles, even fate itself would bend to him as long as he continued indulging in temptation.To Rex, it sounded less like a curse and more like a joke.A joke he was very willing to play along with.Armed with shameless charm, villainous intelligence, and a system that grew stronger the more morally questionable his actions became, Rex carved a path of chaos through kingdoms and noble houses alike.Seduction replaced swords. Manipulation replaced honor. And laughter followed wherever disasters unfolded.Heroes hunted him. Churches condemned him. Empires whispered his name with fear and fascination.Yet Rex never pretended to be a savior.“Villain?” he would scoff.“No. I’m just honest about my desires.”As wars ignited over affection and alliances collapsed over whispered promises, Rex Rexilion rose, not as a hero, but as something far more dangerous:A villain who understands desire better than gods.In this world, righteousness will fall.And Rex will laugh as it burns.----------------------------What to expect:No NTR, No Yuri, A lot of Netori where MC steals someone's girl, pure villain MC, and LARGE harem
