With the Flying Fish Riders taken care of, the Straw Hats rest as Hatchan treats them to the promised Takoyaki. Duval shows up again, not for revenge, but to thank Sanji since his kicks altered Duval's face to become handsome and suave, or so he thinks. To make up for the trouble he's caused, he leaves his Den Den Mushi number with the Straw Hats in case they may need his assistance before departing with the newly christened Rosy Life Riders. The Sunny sets sail for the Sabaody Archipelago, the stepping stone to Fishman Island. Hatchan explains that one needs to have their ship coated with a bubble resin in order to travel underwater, and once they reach Sabaody, he promises to find them a ship coater that he trusts. He also warns them that the world nobility will be on the island, and no matter what happens, not to touch them, even if they witness a murder.
After the surprising reveal, Duval tells his story of living a peaceful life as a mafioso until Marines and bounty hunters came after him for Sanji's bounty, mistaking him for the Straw Hat, casing him to flee and wear a helmet to hide his face. The Flying Fish Riders attempt to drown Sanji by dragging him underwater, but the cook is saved by the intervention of Keimi. Duval then tries to sink the Thousand Sunny by having his men drop a giant anchor on it, but Franky reveals the Chicken Voyage reverse function to dodge it, and then the Gaon Cannon to wipe out most of the Riders. Enraged, Duval orders his pet bison Motobaro to gore Luffy, but Luffy stops the beast by unknowingly using haki, the beast goes wild and then faints, much to everyone's surprise. Sick of everything, Sanji takes things into his own hands, and sends Duval flying into his hut with a faceful of kicks.
The crew splits up in order to explore the archipelago. Hatchan, Keimi, and Paggag lead Luffy, Chopper, and Brook to find the mechanic Hatchan spoke of. In town, they witness a disturbance caused by a man claiming to be an escaped slave yelling for help in getting an iron collar off. To the Straw Hats' horror, the collar explodes, severly injuring the man. Two people wearing gaudy clothing and bubble helmets, Saint Roswald and his daughter Saint Shalulia arrive and callously shoots his body twice before leaving him for the Marines to pick up. Paggag later explains that they were part of the Celestial Dragons, descendants of the founders of the World Government, and that they have the power to summon one of the three Admirals if they so please.
After fighting their way through bounty hunters, Luffy's group arrives at a bar owned by a woman named Shakuyaku, an old friend of Hatchan's. The mechanic, Rayleigh, is not there, so Shakky suggests that they go searching for him at the Sabaody Amusement Park, but not before warning them to be careful, as right now there are nine other pirates on the Archipelago with bounties over 100,000,000 Beli. In addition to Luffy and Zoro, they are: Capone Gang Bege, Jewelry Bonney, Basil Hawkins, Eustass Kid, Scratchmen Apoo, Dies Drake, Urouge, Killer, and Trafalgar Law. Together, the group is known as the Eleven Supernovas.
