Shirahoshi was born in the Ryugu Kingdom on Fish-Man Island, as the youngest daughter of King Neptune of the Ryugu Kingdom. When Shirahoshi was still young, her mother, Princess Otohime, had already called on the residents of Fishman Island to sign a joint document to move to land for the ideal of "peaceful coexistence between humans and fishmen"; Shirahoshi Became her biggest spiritual support.
Later, the explorer and captain of the Sun Pirates, Fisher Tiger, was killed by the navy. The residents of Fishman Island believed that he died because of "human beings' refusal to donate blood", so they were hostile to humans. *Cun felt quite desperate and asked Otohime to return their signatures. Despite this, Otohime still begged the islanders through the radio to think about the future of the next generation, and urged them not to instill hatred for humans in the next generation. Although Shirahoshi was still young at the time, he could sympathize with Otohime's feelings, and he listened to Otohime's teachings when he taught the children of Fishman Island about land.
Ten years before the second part of the story, Saint Musgarud, a Celestial Dragon from the Holy Land, set out to Fish-Man Island in order to recapture the fish-man slaves who escaped from him, but was captured on the way. The ship was damaged by a sea monster attack, so he was seriously injured and drifted to Fish-Man Island. Seriously injured and with nowhere to turn to for help, Saint Musgarud used his arrogant attitude to coerce the residents of the island to help him. As a result, the murlocs who had been his slaves planned to take the opportunity to kill him, but they accidentally injured the murlocs who came to protect Musgar. Otohime of Garudo Saint. However, Musgard Saint not only did not feel grateful to Otohime, but even prepared to attack her with a pistol. Shirahoshi, who was 6 years old at the time, witnessed his mother being attacked. He cried loudly in desperation, accidentally calling the Neptune to the scene, and frightened the Celestial Dragon to the point where he foamed at the mouth and fainted, thus rescuing his mother.
Everyone on the island was shocked, and some realized that this was not an accident. Otohime believed that Shirahoshi did not know and could not control this ability at the time, and was worried that her ability would cause the Neptunes to cause chaos, so she specifically asked the three Neptune brothers to protect her, and also mentioned that there would be someone who could lead Shirahoshi's abilities to the world in the future. Key people in the right direction can make a huge difference in the world. On the other hand, Banta Daken IX remembered that his ancestors came to the bottom of the sea to pursue the legendary mermaid princess who even obeyed the orders of sea kings. In order to fulfill the long-cherished wish of his ancestors, he made up his mind to marry Shirahoshi at all costs. As a wife.
After Saint Musgarud recovered from his injuries, Otohime accompanied him to the Holy Land, and a week later brought back a document signed by the Celestial Dragons agreeing to the friendly relationship between mermaids and humans. However, Otohime was in Jilong Kao He was assassinated while collecting signatures from islanders in De Square. At this time, Banta Daken IX took advantage of the chaos and mixed into the crowd, and touched the White Star with his hand with the "Target Fruit" ability. The White Star has since become his sniper target.
At first, Banta Daken IX just threw a letter of proposal to White Star, but later he continued to "pursue" in an intimidating way (there were many weapons and signs of attack at the door of White Star's room) ), forcing Neptune to order a hunt for him, while Shirahoshi stayed in the hard-shell tower for 10 years to avoid snipers. He could not even attend his mother's funeral. Usually, soldiers would deliver meals or ministers would report something. Neither should exceed five minutes. So Shirahoshi's beloved shark, Mekaro, became Shirahoshi's only confidant during his stay in the Hard Shell Tower. Just before Luffy and others arrived at Fish-Man Island, Shirahoshi was deeply saddened by the disappearance of his love shark Megalo, and even Neptune felt helpless about it. However, because Luffy and others defeated the Kraken on the way to Fish-Man Island, Mekaro, who was entangled by the Kraken's tentacles at the time, was able to escape smoothly and return to Ryugu Kingdom to inform Neptune. When Neptune was preparing to host a banquet to entertain Luffy and others in order to thank Luffy and others for saving Megalo, Luffy smelled the aroma of the food and, driven by curiosity, followed the scent to her room, prepared to feast and then left quickly. He went there, but accidentally touched her breast and woke her up. Because Luffy opened the door at will, the ax thrown by Vanderdaken IX flew into the room along the crack of the door. Luffy stepped forward to protect Princess Shirahoshi who was in danger of being sniped, and also learned from her that in the past 10 years, encounter.
In order to prevent her from getting sick from staying in the tower for a long time, Luffy decided to take her for a walk outside the tower and promised to protect her.
After learning about Shirahoshi's wish to visit Umi no Mori, since Luffy couldn't swim and was concerned that Shiro Hoshi was too big and could easily be spotted, Luffy asked Shira Hoshi to apply swimming paint on him before going to Umi no Mori. layer, and let her hide it in Megalo's mouth. But on the way, Megalo felt quite uncomfortable. When he reached the limit of tolerance when he arrived at Coral Hill, Shirahoshi slipped out of his mouth, causing Luffy to be mistaken for the prisoner who kidnapped Shirahoshi. Her appearance was automatically petrified on the spot, but Sanji's problem of nosebleeds after seeing the beautiful woman was cured without medicine.
At the same time, Vander Deken IX arrived and proposed to Shirahoshi, but Shirahoshi rejected him face to face because he was not his "type". Vander Deken IX was furious because the "love" he had been waiting for for ten years was rejected. He showed his murderous intentions to Shirahoshi, but was easily repelled by Luffy.
After arriving at Uami no Mori, Shirahoshi fulfilled his wish to pay homage to his mother, and listened to Gebel's past with Luffy and others. As a result, he and Nami, who were in a similar situation, hit it off and even felt sympathy for each other. emotion. When Shirahoshi learned that his father, Neptune, was captured by Hody Jones, he went to Gironcaude Square with Gibel and Mekaro, but fell into Hody Jones's trap and was captured together with Gibel.
In the square, Hody Jones revealed that he was the real murderer of his mother, Otohime, and attempted to give Shirahoshi a mental blow, but Shirahoshi mentioned that he already knew it. It turns out that a few years after Princess Otohime was assassinated, she was informed by Megalo who witnessed everything. However, in order to comply with Otohime's last words of "do not hate the murderer", she has not disclosed it to the people of Fishman Island for several years. the truth. Even Guiber couldn't help but admire her kindness when she learned that Shirahoshi had concealed the truth.
Later, Shirahoshi and other residents of Fish-Man Island begged Luffy to help protect Fish-Man Island so that the Straw Hats could legitimately participate in the battle against the new Fish-Man Pirates. In order to kill White Star and bury him with the people of Fishman Island, Vander Deken IX threw Noah, the "Oath Boat", towards White Star. In order to prevent Noah from destroying the giant bubble of Fish-Man Island, Shirahoshi stepped forward and blocked Noah alone, but was stabbed through the body by a blade thrown by Vander Deken IX who was hiding in Noah at the time. Later, in order to prevent Noah who was tracking her from destroying Fish-Man Island, she was willing to be injured as bait to guide Noah away from Fish-Man Island, but was pursued relentlessly by Vander Deken IX.
However, at this time Vander Deken IX was killed, and Noah, who had already been far away from Fish-Man Island, rushed straight towards Fish-Man Island; just when everyone was at their wits' end, Shirahoshi prayed strongly It became a call to the Neptune class, who successfully prevented Noah from falling into the Fish-Man Island.
Afterwards, Shirahoshi saw Luffy bleeding profusely after the battle and wanted to donate blood to Luffy for first aid. However, Chopper could only politely refuse Shirahoshi's offer because her blood type was different from Luffy's. kindness. Later, when he returned to the dormitory from the celebration banquet, he was kidnapped by Caribu, and he wanted to take advantage of his brother Greb's boat to Fish-Man Island to abduct Shirahoshi and sacrifice it to "that person". Fortunately, Luffy He was able to escape only by making a rescue move.
Just when Luffy declared war on "Big Mom" ??Charlotte Lily, the Straw Hats were preparing to leave Fish-Man Island. Shirahoshi was sad to learn that Luffy and others were about to leave. Cried out. In the end, Shirahoshi promised Luffy that she would no longer be a crybaby in the future, and she extended her little finger to the Straw Hats and agreed to go with Luffy and the others next time they met, and "we must abide by it until our death". At this point, we parted ways with Luffy and others for the time being.
(PS: When I was young, I agreed with my mother and three brothers to use the little finger of my left hand, and with the Straw Hat Pirates, I agreed to use the little finger of my right hand)
