One Piece: Neither Good nor Evil

One day, she transmigrated into the world she loved most: the world of One Piece. She spent her days with the people she loved most, becoming their family and their crewmate. But injustice still existed in the world. As a Marine, she upheld the justice she believed in. In that great war, she stood firm and saved her brother Ace, then was sent to the Marine's human-modification base, G-1. But she returned in glory, leading a group of Marine "problem children"! Mary Geoise, the Celestial Dragons, the World Government? There was never any such thing as absolute justice, nor absolute privilege! So what if she was the "Rebellious Rear Admiral"?
