Summary:
The Straw Hat Pirates are ambushed by a group of bounty hunters led by Cider at Sea. After fleeing the attack, the Straw Hats head to an island with carbonated water. Luffy separates from his crew to explore the island. The bounty hunters attack him again, but Luffy also meets Boa Hancock again. They later go to the Cidre Guild stronghold and meet Cidre.
Buena Festa contacts bounty hunter Cidre to reveal that Douglas Bullet will be attending the upcoming Pirate Festival. Cidre looks forward to killing all the pirates involved, whose total bounty is estimated to exceed 10,000,000,000 Beli, but intends to destroy Bullet in particular. Festa says that Bullet isn’t the only attraction, as Monkey D. Luffy was also invited, but Cidre reveals that his guild is already working on taking down the Straw Pirates.
Out at sea, the Straw Hats are under attack from the Cidre Guild, who fly saucer-shaped vessels. Under the command of Ginger and Guarana, they blast the Thousand Sunny with carbonated water from special cannons. The Straw Hats take down many of the members, but they are still overpowered, so they manage to escape with a Coup de Burst. Upon landing, the crew realizes that the Cidre Guild uses carbon dioxide in their attacks like the Sunny, and they immediately go to repair the damage to the Sunny. This leads them to discover that the ship’s supply of coke has run out, and they decide to get more as soon as possible in case the Cidre guild attacks them again. Fortunately, they reach the island very soon and Luffy volunteers to go and buy a keg of Coke.
Luffy heads to the island to find it contains a pool of carbonated water and sits with his feet in the pool drinking a bottle of Coke. After drinking it all, he runs into a saleswoman, Ramune Caramel, who reveals that she can only buy a whole keg of carbonated drink from the island’s factory. However, he warns that the island is under the control of the Cidre guild. Luffy runs towards the factory, but is confronted by Ginger and his subordinates. Luffy fights them, but is hit by a powerful carbonated liquid attack that forces him to fall into a chasm, where he is swept away by an underground river.
Elsewhere on the island, Boa Hancock is taking a bath when Luffy suddenly emerges from one of the gargoyles. Hancock is very upset and happy to see him again. However, Guarana informs Cidre that Hancock and Luffy are on the island together, and Cidre decides to take the opportunity to take them both down and blame Hancock for Luffy’s death. Ginger then leads her forces to Hancock’s bathing spot, where they are attacked by Sandersonia boa, Marigold boa, and Elder Nyon. However, Ginger breaks through them and the wall and they enter the tub. Luffy stands in front of Hancock to hide his Hovering Dragon Hoof, but Hancock also stands and assists in attacking them. Nyon gives Hancock her clothes and the group takes down all of Ginger’s underlings. Ginger, who was the last one standing, releases carbon dioxide gas, forcing Luffy and Hancock to escape together while Sandersonia, Marigold, and Nyon are separated from them.
Guarana reports to Cidre that Luffy and Hancock are heading for the factory, and Cidre decides to go after them himself. Near the factory, Luffy apologizes for getting Hancock involved in the recent fight, but Hancock is happy to see him, thinking they won’t meet again until the Pirate Festival. Unaware of what it is, Luffy reveals that it is an event that happens at random intervals where powerful pirates gather from around the world. Luffy is intrigued, but Cidre then flies in and attacks, blasting a hole in the ground with a carbonization-powered punch. Luffy tells him he just wants a Coke, but Cidre says he won’t sell any to the pirates. He and his subordinates confront Luffy and Hancock and he attacks Luffy to get his 100th kill.
