One Piece: My Second Uncle is Kizaru

He travels back in time to become Admiral Kizaru's nephew, Kyle, and simultaneously awakens the Pirate Game System. Just as Kyle is at a loss as to how to activate the system in Marineford, Kizaru recommends him as a spy to infiltrate the pirates! Thus, the world's most prestigious Dusk Pirates officially set sail! On the seas, Tashigi, wielding her Shura-like three-sword style and a Zanpakutō, appears. Nami, suspended between heaven and earth, cries out, "Incarnation of the Wind, at your command." Enel unleashes the Ten Thousand Thunder Prison, shouting, "For the glory of the Northern God!" The world enters an era of chaos! Also known as: "Pirates: I Can Add Character Templates to My Partners," "The Navy and Pirates Are All My People, What Can You Fight Me With!" PS: Momonosuke must die!!!
