ONE PIECE S15 E517

One Piece - 0517 - The Beginning of The New Chapter! The Straw Hats Reunited!
Two years have passed since the war at Marineford, and the Straw Hat Pirates have since trained for their return. Luffy departs Ruskaina to the Sabaody Archipelago to reunite with his crew and Zoro visits Rayleigh and Shakky in her bar. At a local tavern, Nami learns the Marines have switched their headquarters with their G1 Branch to be next to the Four Emperors. At the Sabao Dome, Brook holds his farewell concert as the Soul King and Sanji and the Okamas go their separate ways. Nami refuses to join a group of pirates who say they are the Straw Hats, but as soon as she is threatened, Usopp shoots down the fake pirates. Nami and Usopp finally reunite and Usopp reveals his new Pop Green weapon. Nami and Usopp flee, but not before she launches Weather Balls at the pirates. As the Marines are summoned to the archipelago to capture Luffy, Robin discovers Brook's concert pamphlet and a recruitment notice with two World Government agents in hot pursuit, Franky waits with the coated Thousand Sunny, and Chopper is excited at the Straw Hats' reunion. Just as the fake Straw Hats try to find Nami and Usopp, the real Luffy bumps into them.
