Location: Fish-Man island

Hello, I'm the Narrator, a YouTuber, and the creator of the altered Nintendo main character, Mario Mario, oh! By the way, Mario is now 27 years old!

The captive human pirates are celebrating their release from Hody's bonds. One of them calls out that they owe a debt to the Straw Hat Pirates while others declare they will be Pirate King and go to the New World. The Minister of the Right asks Neptune what would happen if their grudge against Hody extends to the fishmen. Neptune tells him that is a different matter. He tells him Fish-Man Island was originally a tourist destination for pirates, so they do not need to stay on the island. Neptune then addresses the remaining New Fish-Man Pirates. They beg for their lives, saying they had no idea Hody killed Otohime or how crazy he was.

Neptune then declares they will live in the main area of the island, much to their surprise. The people living on the island, say that if they allow the pirates to live on the island, the children will be too frightened to go outside. Neptune clarified, that they would be living on the island under the surveillance of his army, doing hard labor where they can flex their muscles to atone for their crimes. Neptune then declares the Fish-Man District officially condemned. the darkness of Fish-Man Island has been brought to the light due to Otohime's true assassin. But Hody Jones' invasion plan was stopped, oddly enough, by pirates who were just passing by. Neptune asks where Luffy went. Fukaboshi tells him he (and his crew and Jinbei) ran away.

The scene changes to the Straw Hats, who are flying above the island on the Thousand Sunny, still toting its bubble balloon. Shirahoshi follows alongside the ship and asks why they left in such a hurry. Zoro is mad at himself for fighting in that big of an open area. He tells Shirahoshi that if they had stayed any longer, the people would have lifted them like heroes, shivering at the thought. Zoro tells Shirahoshi that heroes have to share their alcohol, something which he does not want to do. Nami is appalled to hear Zoro reciting the same reason Luffy told Jinbe.

"Uh, Zoro," said Mario "heroes are not like that"

Looking over her shoulder, Nami sees Luffy trying to convince Jinbe to join the crew. Jinbe replies that he cannot join, but is very happy to be asked. He tells them that he has some business that he has been putting off for a long time. After he has taken care of it, he promises he will come back to them and asks them to promise to invite him again, should they still see him fit to join. Sanji tells Luffy not to back Jinbe into a corner. Robin remarks that he has taken a liking to the crew. And Franky remarks that of course, they would wait for a man who captivated Luffy as much as Jinbe did. Zoro then asks if they should head to the New World now. Shirahoshi is upset by their departure and asks them to stay so she can thank them all. Sanji uses this opportunity to propose staying at the Mermaid Cafe for a whole week. Usopp slaps him, saying there is only one reason Sanji would go there, but he does agree with him. Mario just comments: "Bruh"

An Ammo Knight calls out to them and then informs Neptune via baby Den Den Mushi that they caught up to the Straw Hats' ship. Through the Den Den Mushi, Neptune tells Luffy he wants to pick up where he left off with the banquet he initially promised. Luffy agrees and tells Neptune he will get Hatchan and Camie as well.

Meanwhile in the Fish-Man District, where all the buildings have been wrapped in yellow tape. It then goes to Ryugu Palace, where Hody, his officers, and Vander Decken IX are all in a prison cell, still unconscious. At the main entrance to the island, guards are telling Surume to carry Wadatsumi to the far ends of the earth, telling the giant fish-man that they do not have a cell that can hold him and that he is banished from the island. In Coral Hill, people are preparing food to bring to the palace banquet. They are carrying large racks of Sea King meat, boxes of seaweed cakes and other sweets, and alcohol by the cartload, enough to bathe in, as one fish-man put it.

At the palace, the Straw Hats and their guests are being carried on two large flounders to the banquet hall, a completely inundated room, which makes some of the Straw Hats nervous. Below them on the floor packed with soldiers, guards cheer and say the heroes have arrived. Luffy tells them not to call them heroes as he is going to eat all the meat. Shirahoshi points out a stage in the front of the room to Luffy, and they notice someone standing on it. The woman on stage is introduced as Maria Napole, a singer called the diva of the ocean floor and the pride of the island. Maria Napole begins to sing, and her voice completely entrances Nami and Usopp, who feel as if they could melt from hearing it. Brook gets excited, as he notices Maria Napole's accompaniment, a jazz quintet. The music starts up, and then it is Sanji's turn to be in awe, as the Mermaid Cafe dancers are introduced. More mermaids come in carrying trays of food that they take to the Straw Hats and the rest of the people in attendance. Mario enjoys all of it. Everyone is singing, dancing, cheering, and enjoying the festivities. Pappag is dancing with the Medaka Mermaid Quintuplets. Luffy, Mario, and Jinbe are eating and laughing with two other mermaids. Zoro, Franky, and Hatchan toast gourds of alcohol. Sanji turns to stone in the arms of two mermaids, while another one grabs Brook and starts kissing him on the cheek. Luffy is then seen having a toast with Usopp, Neptune, Shirahoshi, Camie, Jinbe, and the Minister of the Right. All the soldiers raise their glasses high. Robin is seen laughing and drinking with the Minister of the Left. Brook is playing his guitar on stage with Maria Napole. Nami is seen celebrating her victory against Fukaboshi in a drinking contest, while Ryuboshi and Manboshi dance together.

Robin is then seen standing just outside the banquet hall, when Neptune, a bit tipsy from drinking, stumbles out. He asks Robin what she wants to talk to him about. Robin apologizes, saying she thought they would be able to be alone. Neptune, thinking she was coming on to him, starts telling Robin he could never betray the love he has for his wife, dead though she may be. Before he can go on, Robin cuts him off, asking who Joy Boy is. Neptune drops his gourd in surprise. Robin goes on to tell him that she read the pone-glyph in the Sea Forest, and then asks Neptune who he was and what he was apologizing for. Neptune, instantly sobering up, is surprised Robin can read pone glyphs. Robin explains she is from Ohara and Neptune does not have to tell her anything he does not want to. Neptune says he will tell her what he knows.

Neptune explains that Joy Boy was a person from the surface who lived during the Void Century. His message was for the Mermaid Princess living on the island at that time. It is an apology for breaking his side of a promise he made with the island. Neptune tells her he does not know the details of the promise, only that someday someone is supposed to come and carry out the promise made by Joy Boy. He explains it is a legend passed down in the royal family. Neptune says that their promise to Joy Boy was to watch Noah and keep him safe. Only when the promised time comes will Noah's purpose be known. Robin tells Neptune that she heard that Noah, after the events in and above Gyoncorde Plaza, was carried to the Sea Forest by Sea Kings. Robin asks Neptune if Joy Boy can control Sea Kings. Neptune tells her that ability belongs to the Mermaid Princess from then and now. Robin then concludes that Shirahoshi has the ability, to confirm her theory. Neptune says she is right, and today that ability was fully awakened, which is not a good thing. Robin agrees. She then tells Neptune about the pone-glyph she read while in Skypiea two years ago. It gave the location of one of the ancient weapons and said it was located on Fish-Man Island. She then asks Neptune if the Mermaid Princess from Joy Boy's time went by another name. Neptune starts to understand. Robin tells him that Shirahoshi, by having the same ability, also inherited the same name as that princess. Her other name is the ancient weapon, Poseidon.

Robin and Neptune continue their conversation, and Robin mentions that there are three ancient weapons: Pluton, Uranus, and Poseidon. Then Neptune warned her not to tell anyone about Shirahoshi for fear that the government and pirates would hunt her. Caribou is eavesdropping on their conversation and goes to kidnap Shirahoshi. Meanwhile, Jinbe tells Luffy and Straw Hat Pirates about the major events that took place during the time skip. The first is Aokiji and Akainu's duel to decide who will become the new fleet admiral, which Akainu won after ten days of fighting. As a result, Aokiji left the Marines, which angered Mario. The second is Blackbeard, who conquered all of the Whitebeard Pirates' territory, claimed the Emperor's seat in the process, and began his hunt for Devil Fruit users to obtain their powers. Luffy, Zoro, and Sanji then leave the conversation to check on Shirahoshi.

The trio finds Caribou in the process of kidnapping Shirahoshi and Luffy proceeds to kick him from the tower. Sanji later gets jealous. After hearing from Neptune that Caribou stole the treasure, he tells Nami that he will give it to them as a reward for saving his country if they can get it back. After Nami finds out that Luffy has kicked Caribou out of the tower, she sends Luffy, Zoro, and Sanji after him so she can have the treasure. Then she gets beaten up by Mario, saying that lives are more important than money.

Neptune is then told by one of his soldiers that something has happened to Hody and his crew. When he reaches their prison cell, he finds Hody Jones and the New Fish-Man Pirates have become very old and are planning on taking their revenge against the Straw Hats. The Minister of the Right deduces that the Energy Steroids, which came from inside the Tamatebako (national treasure of Fish-Man Island), are the cause and Hody confesses that he stole them. Neptune then tells them to forget about their intention of seeking revenge against humans considering the state that they are in and says he will have to re-think their punishment.

Meanwhile, a soldier comes to the Minister of the Left, reporting that two of Big Mom's men have come to the island to collect her monthly candy payment. Unfortunately, because the candy factory was destroyed by the New Fish-Man Pirates and the remaining sweets were sent to the party, there is not enough candy for Big Mom this month. The Minister of the Left is then worried about Big Mom's reaction, saying that she is "a monster who would destroy a country for the sake of sweets".

Meanwhile

Jinbe and Neptune are talking in Ryugu Palace. Neptune asks how the Sun Pirates are doing under Big Mom's jurisdiction. Jinbe says that she is not the most reasonable boss but they have been free to do what they want. Neptune comments how it must be hard for Jinbe to take orders from someone who wasn't Fisher Tiger. Jinbe replies that he is not picky about who his boss is and that it is a good strategy to serve an Emperor to ensure his crew's safety. Neptune is surprised since he thought Jinbe did it for the sake of Fish-Man Island because thanks to Jinbe, the island was kept safe under Big Mom's name. Jinbe remarks that it is just a coincidence and that he and his crew should be protecting the island, but cannot since they are wanted pirates. Jinbe then announces that he will cut off ties with Big Mom. Neptune concludes that this is because Jinbe wants to join the Straw Hats. Jinbe adds that verbal contracts are a lot harder to get out of than written agreements and that there is a chance Big Mom will direct her anger at the island. Neptune tells him he is taking too much responsibility, adding that the army just gained another seventy thousand soldiers from the Fish-Man District and he has found another flag he wants to borrow: the Straw Hats', an idea which Jinbe likes.

The Minister of the Right comes in out of breath, saying he remembered something important about the treasure given to the Straw Hats. They must return the tamatebako. There is a bomb in it and it is rigged to explode upon opening. The minister did this after it was stolen ten years ago as a safety precaution. Neptune agrees that they will ask them to return it. A guard enters and announces the Straw Hats have returned. Nami, Neptune, and the Minister of the Right are then shocked to hear that Luffy, Zoro, and Sanji gave the treasure to Big Mom. Luffy tells them she is going to destroy the island, that she is crazy, and that he will fight her, stunning everyone except Shirahoshi and Mario. Jinbe realizes that now he must leave Big Mom before things get even worse. He suggests that the Straw Hats must not irritate her more than they have. The Minister of the Right whispers to Neptune that Big Mom might take the bomb as an act of war. Nami then sympathizes with Luffy, saying he stood his ground the way any man would. She then hits Luffy, Zoro, and Sanji for giving away all of the treasure, she later pays for punching them, and she gets bonked by Mario. Luffy then declares they should go to the New World.

Outside the Candy Factory, Caribou has woken up and realizes that all the treasure he stole is gone. He says that if he brings back the princess and the treasure, then he could get on a certain person's good side. He then sees a crowd of people by Tamago and Pekoms, who are carrying three large bags. Caribou realizes they must have the treasure. He charges at them, demanding the treasure back. Pekoms recognizes him and looks him up in a book. A Gatling gun extends from Caribou's stomach and he shoots at Pekoms. Pekoms is knocked over but when the dust clears, he is seen hidden inside a tortoise shell. Caribou realizes he must be a Zoan. He flies at Pekoms with a scythe. Pekoms blocks the attack with a single Haki-imbued punch, shattering the scythe and sending Caribou flying. Pekoms afterwards, mentions that the downfall of a Logia is its oride of invincibility. Pekoms and Tamago then leave.

Meanwhile near the Red Line. Marines are fighting multiple pirate ships coming from the sea. Someone shouts that Captain Tashigi is in trouble. Two lovestruck Marines try to embrace her to protect her. She jumps out of the way and toward an incoming cannonball. Using her sword, she manages to redirect the cannonball, which blows up away from the ship. The two soldiers cheer, but she tells them to stop messing around. She berates them, not knowing she is yelling at the ship's mast. She asks how they could be joking around right now. She then accuses them of teasing her for being a woman. Smoker tells her to be quiet since he is in the middle of an interrogation. Smoker turns toward his prisoners, reiterating that pirates were being enslaved by Hody Jones, citing that as the explanation why no rookies came through Fish-Man Island in the last month. But now, they are coming out of the sea practically non-stop. The captured pirates then go on to say that there was a pirate who stopped Hody's war, ultimately freeing them. However, he will not tell Smoker the name. One guy shuts him up, saying that they are dealing with G-5, listing rumors of their torture methods. Other Marines ask Smoker if they could have the prisoners now. Panicking, the pirate blurts out that it was Luffy who saved them. Smoker tells them that he already knew that.

Meanwhile

Camie tells Shyarly that Luffy and his crew are going to leave the island. Shyarly tells her to go see them off. Before she leaves, Camie notices the broken crystal ball on the floor. Shyarly tells Camie that she is through with foreseeing the future for good, and she could not be happier if she was wrong. Camie realizes her boss is more fearful than anyone, since her prediction may come in a year or more, and there is no way to know if she is wrong. Shyarly asks Camie to forgive her for suspecting her friends of wrongdoing.

The scene changes and Shirahoshi is crying as she holds Luffy in her hand, asking him to stay for another week, then a month, and then a year.

"What a crybaby," said Mario

After seeing Shirahoshi, Sanji wishes he could stay for a year. Brook says that he will call his new single "Life on Fish-Man Island is a Dream". Zoro tells Sanji he should stay on the island. Sanji says he will teach him not to cross the person who cooks his food. Over to one side, the Minister of the Right whispers to Neptune about the tamatebako. Neptune tells him to look at the pirates. Usopp and Chopper are in despair, saying 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 on out. Neptune and the minister realize they could not tell them at this point. Neptune does add that it was ten years since the bomb was placed in there, it may have become a dud. The Minister of the Right says he does have a point, the castle is damp, and Big Mom might not be the one to open the box. Robin wonders what they are whispering about. Fortunately for Mario, he heard everything,.

The Minister of the Left then gives Nami a new Log Pose, with three needles on it instead of one. Shirahoshi lowers Luffy so he can see the new Log Pose. Nami looks at the one on her wrist. She wonders why it is moving since she thought it had already recorded the next island. The minister tells her that each island in the New World as well as Fish-Man Island takes only half a day to record. The islands can differ in current, climate, and magnetic fields, which until now have been the only thing they could rely on. However, some islands lose their magnetic fields. The minister points out 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 the wrong decision could mean certain death. Master navigators can choose the safest routes by observing subtle differences in the needles' movements. The stronger the needle's movement 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, as it looks like fun. Nami and Usopp are devastated that Luffy overheard the conversation. Nami tries to strangle him, saying she is the one who chooses the route, but Luffy says he is the captain. Mario goes Cie-cie! (Mario ships Luffy and Nami) Usopp and Chopper beg Luffy to see sense.

Franky then declares that they are ready to go and he even learns how to float up. Hatchan tells them he is staying behind to help repair the factory. Usopp and Chopper have become more enthusiastic, saying they are going to war in Hell. Sanji and the mermaids say their goodbyes, and Sanji calls them the All Blue of his heart. Fukaboshi thanks Luffy. Manboshi declares that they will be leading the strongest army in the ocean the next they meet, and Ryuboshi says their reputation will be even more renowned. Luffy and Jinbe simply exchange silent looks. As the crew leaves, the people call from the shore that they now like humans, as well as robots, raccoons, and skeletons. Shirahoshi then swims up and grabs the side of the ship, making everyone fall over. She tells him she will not be a crybaby next time they meet and wants to go on another walk with Luffy, only this time she wants to go to the surface and see a real forest with them. She holds out her pinky and Luffy wraps his own around hers, symbolizing the promise. The other Straw Hats, save for Zoro and Franky, all touch their pinky fingers to hers. She then waves as they leave, splashing water on her face and holding her pinky finger. Neptune tells his son not to forget their debt. A child then asks his father for a straw hat so 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 he will send a merchant ship to get the hats.

On the Thousand Sunny, Sanji is reveling in his memories, but Nami tells them there is no time to rest, as they have to go back through the dark sea again. Attached to the foremost mast of the ship is a string of floating blocks. Franky tells Usopp they are called Kuuigosu, and extremely buoyant wood that he is using to raise the ship. Their speed of ascent can be controlled by how many are let out. Luffy is standing on the bow, and Zoro asks him if something is wrong. Luffy says they will be in the same ocean as Shanks when they reach the surface and he is looking forward to seeing him. He then remembers the day Shanks gave him his straw hat. He also remembers the words of encouragement given to him by Ace, Jinbe, and Rayleigh. Finally, he remembers the conversation he had with Koby about the New World. Everyone gets fired up while Robin simply laughs. Mario simply says his iconic "Here we go!" then Luffy shouts:

"We are going to the New World!"
