“Look Left.”Pierre, a professional cynic and amateur MMA fighter, dies in a hilariously ironic argument with the author of a garbage-tier webnovel. His final complaint? The pathetic hero gets stronger by touching women's chests.As a reward for his “passionate feedback,” a bored god reincarnates him into that very world.Now, trapped in a story he loathes, Pierre is given a gift: a leveling system and a power far darker than the hero's “Boobie Boost.” His is called Essence Drain: a parasitic ability to steal power through physical contact, an intimate violation that feels dangerously good.The hero of this world can have the plot armor and the clichés. Pierre will use his intellect, his brutal new power, and his insider knowledge to hijack the story. His first move? Steal the hero's fated beautiful navigator before they can even meet.They call him a menace. A criminal. A terrorist. Fine. If fighting a world run by corrupt Marines and preening nobles makes him a villain...He'll become the greatest villain the world has ever seen.-----------Additional tags:No Incest, No Rape, No Yuri, Harem, No Loli, One Piece, Transmigration, Pirate, Pirates, Princess, Shonen, No NTR
