Long Summary
The chapter starts with Luffy saying goodbye to Rayleigh and thanking him once again while a voice off-screen yells "Capture Straw Haaaaaat!" There is a brief flashback of two instances during Luffy's training, Rayleigh then tells Luffy to aim for the top. Luffy, Zoro, and Sanji leave just as the Marines arrive. Rayleigh draws his sword, asking the Marines to respect the departure of his pupil. He then draws a line in the dirt with his sword's blade, saying that it would be a bad idea to cross the line. Elsewhere, the Monster Trio﻿ is surrounded by more Marines. Suddenly, a Negative Hollow appears. Perona then appears, seemingly annoyed at the disturbance they were causing, asking what they were still doing there and why they hadn't left yet. The Marines behind her are suffering the effects of her Negative Hollow. Sanji (and obviously Zoro) recognize her, while Luffy doesn't. Perona then chastises Zoro for sounding ungrateful, reminding him that if it hadn't been for her, Zoro would not have reached the archipelago. She then tells them to hurry up since Marine vessels were right next to island.

Meanwhile, at Thousand Sunny, the crew members who had already arrived are rejoicing in seeing each other again. Brook, for the first time in two years, asks Nami if he could see her panties. Before he could finish his question, Nami promptly kicked him in the head, sending him flying into the wall. Nami then states that no one had matured during the the two years they were separated. Chopper had gone to look for the others. Then, Luffy, Zoro, Sanji, and Chopper all arrived on one of the giant birds from Torino Kingdom. Everyone is overjoyed to see the last three crew members. Sanji, upon seeing Nami and Robin for the first time in two years, breaks out in a nosebleed so massive that the pressure from the gushing blood seemingly launches him from the bird. Once on the ship, Usopp tells Chopper to stop Sanji's bleeding. Luffy can't help but marvel at Franky's new modifications. Nami tries to pull him out of this trance, saying they have bigger problems.

Suddenly, Thousand Sunny is bombarded by cannon fire. A Marine ship was already in range of the Straw Hats. The second round of cannon balls is stopped by Slave Arrows. The Kuja Pirates' ship intercepts the Marine ship, stalling their attack on the pirates. Robin identifies the ship as belonging to the Kuja. Usopp is shocked by Boa Hancock's beauty. Sanji momentarily turns to stone as a result of seeing her. Usopp wonders why a Shichibukai would be at the archipelago. Hancock winks at Luffy. Brook sees this, causing him to fall over in shock. Nami asks Luffy if he knew her. Luffy explains how he met her on the Isle of Women. Usopp is surprised by the fact that such an island actually exists. Sanji yells at Luffy out of jealousy with tears in his eyes. Marguerite and Sweetpea comment on the appearance of Luffy's crew.

Franky then states that he will open valves so that air can flow in from the sack under the ship. The ship's coating starts to expand, forming a giant bubble around the ship, covering the deck with a bubble roof. Chopper then notices Usopp looking out at the archipelago and asks him if something is wrong. Usopp asks if all the Marines had been defeated. Chopper says that he didn't think so. Usopp then comments that no one was chasing them. No one else seems to be bothered by this, some even calling it luck. It is soon revealed why there are no Marines following them.

The scene changes to the Marine's third backup platoon. They state that they cannot pursue the Straw Hats because giant insects, under the command of Heracles, were blocking their path. Heracles then wishes Usopp a safe journey. This happened to all the other Marine platoons. The fourth platoon's gunpowder was ruined by a sudden rain, that was isolated to only their location. It is revealed that the rain came from Weatheria, which was floating right above Sabaody Archipelago. Haredas and the other scientist were creating more diversions so that the crew could set off safely. Haredas then says that it will be lonely in Weatheria without Nami. The fifth platoon reported that the second platoon had gone completely negative, being held off by Perona. They also reported that the pirates escaped on a giant bird, which confused the person talking. Another platoon was intercepted by the okamas, claiming their hearts were about to be crushed; this affected Sanji too. One of the okamas said that now was Sanji's chance to escape.

Back at the Sunny, Nami started to explain how coated ships work. They have the ability to reduce various pressures, meaning that the ship cannot stay buoyant. The air sack is the only thing keeping the ship afloat at the moment. Both Luffy and Zoro simultaneously said that they did not understand. Franky resurfaces, saying that he had removed the air sack. Nami ordered everyone to raise the sails while they submerge. This confused Usopp, who thought that the ship would move on its own once underwater. Robin explains that underwater, ocean currents act as the equivalent of wind, thus, the currents move the ship. Luffy asked Nami if they were ready to go, to which she replies yes. Luffy then shouts that he has a lot of things to tell them, but for the moment wanted to thank them for putting up with his selfishness for the last two years. Usopp and Sanji sarcastically ask if he thought that that was anything new, saying Luffy had always been like that. A Marine shouts to his commanding officer, a Rear Admiral, that the Straw Hats were escaping underwater, saying so while only the very top of the mast was still visible. The Rear Admiral, as well as the rest of the Marines, were being held captive by Boa Hancock's beauty. Luffy then screams "SET SAIL!" The chapter ends with the crew underwater, heading toward Fishman Island.
