Summary:
Mermaids and Camie from the Mermaid Cafe ask Madam Shyarly if they can say goodbye to the Straw Hats. Madam Shyarly says that her prediction that Luffy will destroy Fish-Man Island may not come true after all since they defeated Hody and the New Fish-Man Pirates.
Meanwhile, Shirahoshi cries and asks the Straw Hats not to go. Usopp and Chopper complain that they will die in the New World. The Minister of the Left gives Nami a new Log Pose from the New World with three needles so they can get to the islands in the New World. The Minister of the Left is explaining the features of the new Log Pose when Luffy suddenly grabs Nami and wants to see the new Log Pose. He complains and says he’ll tell the crew where to go, but Luffy complains that he’s the captain so he should decide where to go. Franky gets a haircut and they start to leave, but Shirahoshi comes in and asks them to make Pinky promise to come back, and the crew does.
The Straw Hats finally leave and some kids from Fish-Man Island ask their parents if they can get a Straw Hat similar to Luffy’s and Jinbe says he will get one. Luffy then remembers the times when Shanks, Rayleigh, Jinbe and Ace told him something important. The Straw Hats then comment on what they will do when they are in the New World.
Camie tells Shyarly that Luffy and his crew are about to leave the island. Shyarly tells her to go see them off. Before she leaves, Camie notices a broken crystal ball on the floor. Shyarly tells Camie that she’s done predicting the future for good and couldn’t be happier to be wrong. Camie realizes her boss is more scared than anyone else because her prediction could be a year or more away and there’s no way to know if she’s wrong. Shyarly asks Camie to forgive her for suspecting her friends of wrongdoing.
The scene changes to Shirahoshi crying as she holds Luffy in her hand, asking him to stay another week, then a month, then a year. After seeing Shirahoshi, Sanji wishes he could stay a year. Brook says he will call his new single “Life on Fish-Man Island is a Dream.” Zoro tells Sanji that he should stay on the island, calling him “nosebleed-kun”, much to Sanji’s anger. Sanji says that he will teach him not to cross the person who cooks his food. On one side, the minister of the right whispers to Neptune about tamatebac. Neptune tells him to look at the pirates. Usopp and Chopper are in despair and say they are going to the New World to die. Chopper wonders if Big Mom would forgive them if they gave her all their treasure from here. Neptune and the Minister realize that they couldn’t tell them at this point. Neptune adds that it’s been ten years since the bomb was placed there, maybe she’s gone crazy. The minister of the right says that he is right, the castle is damp and Big Mama may not be the one to open the box. Robin wonders what they are whispering about.
The Minister of the Left then gives Nami a new Log Pose with three needles instead of one. Shirahoshi lowers Luffy to see the new Log Pose. Nami looks at the one on her wrist. She wonders why he is moving as she thought he had already noted another island. The minister tells her that every island in the New World, like Fish-Man Island, only takes half a day to record. Islands can vary in current, climate, and magnetic fields, which until now was all they could rely on. However, there are also islands that lose their magnetic fields. The minister notes that only one needle on the Log Pose is shaking, while the other two are completely still. Each needle records the waves of a different island, meaning the navigator must choose which way to go, and a wrong decision can mean certain death. Master navigators can choose the safest routes by watching for subtle differences in the movement of the needles. The stronger the movement of the needle, the more dangerous the island. Nami finds this new navigation method deeply disturbing. Suddenly, Luffy wraps his neck around Nami and notices the center needle shaking. He decides to go to that island because it looks like fun. Nami and Usopp are devastated that Luffy overheard the conversation. Nami tries to strangle him, saying that she is the one who chooses the path, but Luffy says that he is the captain. Usopp and Chopper plead with Luffy to see sense.
Franky then states that they are ready to go and he even learned how to float. Hatchan tells them that he is staying to help repair the factory. Usopp and Chopper were more excited and said they would go to war in hell. Sanji and the mermaids say goodbye and Sanji calls them the All Blue of his heart. Fukaboshi thanks Luffy. Manboshi states that they will lead the strongest army in the ocean when they meet, and Ryuboshi says that their reputation will be even more famous. Luffy and Jinbe just exchange silent looks. As the crew leaves, the people from the shore call out that they like humans now, as well as robots, raccoons, and skeletons. Shirahoshi then swims up and grabs onto the side of the ship, causing everyone to fall. She tells him that the next time they meet, she won’t be a brat and wants to go on another walk with Luffy, but this time she wants to go to the surface and see the real forest with them. She holds out her little finger and Luffy wraps his around it, symbolizing a promise. The other Straw Hats, except for Zoro and Franky, are all touching their pinky fingers to hers. Then he waves as they leave, splashing water on his face and holding his little finger. Neptune tells his son not to forget his debt. The child then asks his father for a straw hat so that he can play heroes with it. His father then tells him that they are only available on the surface. Jinbe overhears the conversation and tells them that he will send a merchant ship for the hats.
On the Thousand Sunny, Sanji revels in his memories, but Nami tells them that there is no time to rest as they have to go back across the dark sea again. A string of floating blocks is attached to the forwardmost mast of the ship. Franky tells Usopp that their name is Kuuigosu and the extremely buoyant wood he uses to lift the ship. Their rate of climb can be controlled by how many are launched. Luffy is standing at the bow and Zoro asks him if something is wrong. Luffy says that when they get to the surface they will be in the same ocean as Shanks and he looks forward to seeing him. He then remembers the day Shanks gave him his straw hat. He also remembers the words of encouragement Ace, Jinbe, and Rayleigh gave him. Finally, he remembers the conversation he had with Koby about the New World. Everyone goes into a rage while Robin just laughs. The episode ends with Luffy yelling that they are going to the New World.
