One Piece: Lurking in the Shadows, Yet They Think I'm Weak

Transmigrated into the One Piece world, awakened the Myriad Worlds Plunder System, and started in the era of Rocks! I chose to lie low in the Marines, starting as a third-class soldier. Garp saw me as a lucky rookie, Sengoku thought I was mediocre. At the Summit War, I was assigned to the safest corner, 'trembling in fear.' They didn't know... At God Valley, I 'accidentally' crippled Rocks. At Enies Lobby, I secretly freed Robin. Facing Kaido and Big Mom, I dropped the act—these Emperors... aren't that tough? When the final battle came, I tore off decades of disguise and slowly stepped out from the Marine ranks. Im and the Five Elders realized in horror that the 'Shadow Emperor' who had loomed over the entire history of One Piece—had been right before their eyes.
