One Piece: My Second Uncle is Kizaru

Transmigrated into the biological nephew of Marine Admiral Kizaru, Kyle, and simultaneously awakening a pirate game system. Just when Kyle is at a loss, not knowing how to activate the system in Marineford, he is actually recommended by Kizaru to become a spy infiltrating the pirates! From then on, the most prestigious Twilight Pirates in the world officially sets sail! On the sea emerges a demonized three-sword style, and Tashigi wielding a Zanpakuto. Nami hangs between heaven and earth, exclaiming: "Incarnation of the wind, at your command." Enel unleashes the Myriad Calamity Thunder Prison, shouting: "For the glory of the Northern God!" The world ushers in an era of great chaos!
