Summary:
The Straw Hat Pirates get separated after escaping from The New Fishman Pirates, and Luffy, Usopp, Sanji, and Chopper run into Camie and her friends. They follow the New Fishman Pirates after being told to bring the Straw Pirates to their boss. The Neptune Brothers arrive in search of the Straw Hats, but Sanji suffers a near-fatal nosebleed, causing the Straw Hats and Camie to quickly leave in search of a blood donor. After the Straw Hats and Camie leave, the Neptune Brothers reveal to Camie’s friends that they were trying to deliver a message from Jinbe to the Straw Hat Pirates.
The episode opens with a deranged Sanji playing in the mermaid pool at Mermaid Cove. The chef expresses his desire to live there and the mermaid remarks how fun he is. Luffy dips his feet on the side of the pool and comments on how beautiful swimming must be. Camie suggests that Luffy could wear a bubble to do this, much to his surprise. Usopp questions if Sanji is acting out of character. Chopper says that he is glad that Sanji is back to normal, and goes on to say that his blood supply is outside of Sanji’s blood type, S RH-, an extremely rare blood type. Luffy tells Camie that there is someone on the island he wants to meet. Camie asks if she’s a mermaid princess, Luffy says no and that he wants to see Jinbe and explains how Jinbe helped him cope with the loss of his brother Ace. Usopp asks if Luffy is talking about the former Shichibukai, to which Luffy says yes and calls him his friend, much to Usopp’s disbelief. Luffy then remembers that Jinbe said he would wait for Luffy at Fish-Man Island and tell Camie about it. Camie remembers reading an article where Luffy and Jinbe were seen together.
When Luffy asks where he is, Camie replies that he is not on the island, explaining that after Jinbe abdicated his Shichibukai status, he could no longer stay on Fish-Man Island, so he and the Fish-Man Pirates had to leave. Luffy then asks if that meant he wouldn’t be able to see him, and Camie explains that the details of his departure are complicated and that a lot has changed on Fish-Man Island since the war.
They are interrupted by the Medaka Mermaid quintuplets who come to tell them that a ship is approaching. Nika, one of the five, tells Camie that it is a rare royal ship. Realizing that the ship may be coming to arrest Luffy, Camie tells the crew to hide. Luffy, Usopp, and Chopper all hide behind rocks while Sanji, still in the water, is shielded from the sight of Ihilla, who tries to tell him to stay calm while pressing his head to her chest, which the chef, as he seemed to enjoy it immensely. . A ship that Camie identified as a royal gondola, basically a large oar with some sort of carriage with oars sticking out, approaches them. A nearby mermaid does not believe that there could actually be kings on board and wondered why they would come from Ryugu Palace to this small corner of the island. Trumpets are then heard, announcing the arrival of the Princes of the Kingdom of Ryugu, the brothers of Neptune. One of them greets the mermaids that he has a question for them. The three mermaids scream with joy at the sight of the prince and ask them why they are there, while Luffy, hiding behind a nearby rock, watches silently.
He then wonders why there would be princes in Mermaid Cove, as well as Usopp and Chopper. The Neptune princes, Fukaboshi, Ryuboshi, and Manboshi, then come out. Fukaboshi explains that they received a report of illegal entry and asked if anyone had been there. The mermaids reply that no one has come. One wonders if the people they are looking for are really important enough for the three princes to look for them personally. Fukaboshi then states that they have not confirmed if the people they are looking for are illegal entrants.
Hammond watches these events unfold from afar. He is with Fish-Man and a sea monster. Hammond wonders why they are in the bay, saying it could be problematic. Fukaboshi then thanks the mermaids for their time, saying that he will continue searching elsewhere and that the Border Patrol must have made a mistake. He then apologizes to the mermaids for taking up their time, to which they reply that it was no problem at all. His brothers also apologize. At this point, Sanji loses all self-control. The ability to control himself was too much as he pressed his head against Ihilly’s chest and he erupted in his most massive nosebleed ever. The blood shot out extremely high and took the form of a mermaid in a sexy pose. Chopper cries out in shock as she runs towards him. The mermaid holding him screams, not knowing what just happened. The lower half of Sanji’s face is completely covered in blood, and there’s a lot more of it in the water. Luffy notes that Sanji just lost a dangerous amount of blood. Usopp realizes that Sanji ultimately couldn’t handle the excitement and suppressing it caused him to explode like this. While checking some of the crew’s wanted posters, Fukaboshi realizes that the person he sees now must be Monkey D. Luffy. He then orders his knights ammunition to advance. Hammond realizes that the Straw Hat Pirates are now there too. Hammond says that it would be bad for them to get into a fight with the Neptunian army and decides to do nothing for now.
Chopper runs up to Sanji and tells the guards to wait a moment while he apologizes for trespassing and asks the guards to delay their arrest. He then asks for someone to donate blood, saying that if Sanji is not treated, he will die within an hour or so. Chopper said that Sanji’s blood type is S RH-, an extremely rare blood type. He asks if anyone could make any donations and asks if the blood of a fish man or a mer man could be transfused into a human body. The guards stop in surprise. Luffy then begs for someone to give Sanji some blood. As some of the mermaids look on in horror, Chopper asks again if anyone has the required blood type. Usopp finishes the plea by saying that they can’t let Sanji die in such a stupid way. Camie tells Chopper that humans, mermen, and fishmen all share the same blood and that it is transfusible. She is about to explain more but is interrupted by Hammond’s laughter. He tells the Straw Hat Pirates that they must be crazy, and that there isn’t a single creature on the island that would give blood to humans, and if anyone did, they would receive “judgment in the dark” from someone who hates humans. . Luffy then recognizes Hammond from their earlier encounter when Camie suddenly dives underwater.
One of the guards tells Fukaboshi that the one speaking is Hammond from the Fish-Man District. Hammond tells Sanji to stay bleeding as he is and helplessly die. He then tells of a rule that was put in place a long time ago that forbids fish people and humans from sharing blood. Usopp and Luffy look at him in disb
