Summary:

Kenji, a morbidly obese and unapologetic pervert from Earth, dies from overindulgence while reading a trashy harem novel he hated. To his horror and secret delight, he awakens transmigrated into the body of Baron Viktor von Grell — the most despised minor villain in the story. Viktor is the archetypal fat, lecherous noble: a 400-pound sleazebag who preys on young maids, abuses his servants, gropes anything with a pulse at noble parties, and occasionally tries to snatch the Hero’s harem members using his wealth and status. Everyone hates him. The Hero’s party sees him as trash. His own servants pray for his death nightly. But Kenji? He doesn’t resist the role. Instead of reforming or trying to befriend the Hero, he fully embraces his new identity as the ultimate degenerate noble. With the advantage of knowing the original plot, the Hero’s future actions, and the weaknesses of every heroine, he decides to play the villain to the fullest — only smarter, crueler, and far more ambitious. Armed with his twisted modern mind, Viktor’s wealth, shady connections, and a few hidden “gifts” from his transmigration, he begins scheming in the shadows of the Kingdom of Valeria. His goals? Turn his miserable barony into a den of forbidden pleasures and growing power. Corrupt or steal the Hero’s harem members one by one (through blackmail, drugs, contracts, seduction, or raw manipulation). Slowly undermine the Hero while pretending to be the incompetent, disgusting noble everyone expects. Rise from minor antagonist to major threat — perhaps even becoming a new Demon Lord candidate. In a world that already treats him as the worst kind of scum, Viktor has nothing to lose and every depraved desire to satisfy. The Hero may be strong, but the Baron is cunning, rich, and has no moral bottom.
