This Was Supposed to Be One Piece, So How Did I Become a Navy Admiral?

After staying up all night watching anime, Zheng Yi, a die-hard One Piece fan, dropped dead and transmigrated to the world of One Piece. From the start, it was the very day Luffy set sail! But damn it, why have I become a cannon-fodder Marine about to have my throat slit by pirates?! At the critical moment, the “Absolute Justice Enforcement System” activates! [Fail to enforce justice, and the Host dies immediately!] To stay alive, and to get a glimpse of the truth of the world, “ONE PIECE,” Zheng Yi is forced onto a Marine path worthy of an outlaw. He slays criminals, crushes corruption, and wipes out the Celestial Dragons’ lackeys! He believes only in his own justice. Marines and pirates alike tremble beneath his sword! Years later, with Zheng Yi standing atop the Holy Land of Mary Geoise, the Five Elders are horrified. “He’s the most terrifying ‘pirate’ on these seas!”
