Queen Otohime is a goldfish mermaid, queen of the Ryugu Kingdom, wife of King Neptune, and mother of Shirahoshi, Fukaboshi, Ryuboshi, and Manboshi.
Otohime is the queen of Fish-Man Island and the wife to it's king, Neptune. She's skilled in her use of Observation Haki but still frail of body. With her husband, they had four children, Fukaboshi, Ryuboshi, Manboshi, and their only daughter Shirahoshi. She was the foremost advocate for fish-men and mermaid kind to no longer live only in the deep seas but all over the world. She faced heavy opposition due to the deep tensions between both humans and fish-men. She was a kind and gentle queen who cared deeply for her people, and they also held her in deep regard.
One day, Fisher Tiger came to Ryugu Palace to give the royal family a warning that he was a going to take some action that could cause the royal family tension in their dealings with the human World Government. With her ability of haki and deep empathy, Otohime was drawn to tears. While Tiger went out to attack the Celestial Dragons and free all their slaves, Otohime put forth even more effort to try and get the people to sign on for her place to move to the surface with humans.
The character of Queen Otohime is a supporting character in the One Piece series that was created by Eiichiro Oda. The series first began serialization in Weekly Shōnen Jump on August 4, 1997. She would later appear in the Fish-Man Island Arc that began in Volume 61.
Her first appearance was in One Piece Volume 63 CH. 621 "Otohime and Tiger", and her first anime appearance was in One Piece - Episode 540 "A Hero Who Freed the Slaves! An Adventurer Tiger!". Her character in the Japanese series is voiced by Michiko Neya, and the U.S. dub produced by FUNimation has yet to announce a voice actress.
Even after several years, Otohime only acquired the signatures of about 1,000 of the citizen in a population of over 5 million. After word reached Fish-Man Island that Fisher Tiger had died not just from his injuries but from being denied blood from humans. All the people who had signed came back to withdraw their support. The frustration of this failure drove Otohime to over drink and in her inebriated state gave an angry but heartfelt speech to the entire country about how their children deserve better than hiding in the deep ocean.
Jimbei, a former member of the royal guard and now captain of the Sun Pirates, contacted the royal family to tell him he was accepting the position in the Shichibukai for the amnesty it would give the members of his crew that were former slaves. Not to let his sacrifice be wasted, Otohime put forth even more effort to try and sway the people and educate the children. A shocking change came to the island when Saint Myosgard, a Celestial Dragon, arrived thinking he could take back his former slaves. His ship had been damaged during the journey and he was near death. Otohime rushed to the scene and barely managed to shield the man from the gunfire of his former slaves. They dropped their guns after she told them there were children watching them. Myosgard didn't care for this kindness and took Otohime hostage to get a doctor. She was saved when Shirahoshi called forth the Sea Kings inadvertently using the power of Poseidon. After he was healed, Otohime joined Myosgard to the Marie Jois to negotiate with the humans.
Otohime returned a week later with a letter from the World Nobles with the promise to support Otohime if she were to gain enough signatures. She gave a speech to the people at Conchcorde Plaza. It started with a few children but soon people were handing in the signatures in droves. Even days later they were still gathering massive numbers of signatures. She then warned her sons about the power of Shirahoshi and the devastation it could cause if she were to become too stressed. They swore to protect their sister and become strong warriors.
As the signatures were being collected, the boxes were suddenly set on fire. Otohime tried to save the signatures of the people, but such was suddenly shot by someone in the crowd. Her sons rushed to her side as she was dying, Fukaboshi nearly went into a rage, but she made her children promise now to fall into hatred, even against her killer. Otohime then watched as Ryuboshi and Manboshi calmed their sister down from losing control of her power by singing and dancing despite their own tears. Her children gathered around her, and they made one final promise to build the future she had died for.
As a mermaid, Queen Otohime has the inherited ability to swim at incredible speed in the water and communicate with fish. Mermaids are the fastest creature in the water.
The ability known as Haki is in every living person but few ever learn to tap into that power. There are three forms of Haki, but Otohime could only use one. She had the power of Observation Haki (見聞色, Kenbunshoku / Color of Observation). With this ability, she could feel the presence of those around her and even their feelings. This also gives her a deep insight into a persona actions and can read their minds. This power allows the user to predict the movements of others and possibly evade them. Otohime was skilled enough with Observation Haki that she could even dodge gunfire.
