Hanarabi Seikō is a pirate and the Doctor of the Dawn Star Pirates.

Seikō is one of the major figures, along with Sengoku, Shiki, Garp and Whitebeard, from the times when the "Pirate King" was still alive. She also has a long history with Silvers Rayleigh, noting him as one of the few people to clash blades with.

=== ===


Hanarabi Seikō is a short woman with pruned skin dotted with age marks, and a thin frame. Her age shows, with deep wrinkles set around her mouth and bags beneath her dark brown eyes. Her teath are sharpened to a point. Her grey hair is tied in a single bun with two bangs hanging down around her face. She wears a basic black kimono tied with a white obi. She also wears a white haori which has a Dawn Star on the back. She has her assistant Mai carry her sword for her.


Seikō has always been more powerful than others, and this power has isolated her for most of her life. When a young woman, she was in an almost constant state of melancholy as there were no opponents able to stand against her might. Beneath her well-crafted guise, she harbours a bloodthirsty nature and is infatuated wish crossing blades. This is the reason why Seikō has Mai carry her blade, to prevent her from releasing her demons and keep her trained on her duty to tend to the wounded.

Many of the truths of Hanarabi’s personality are hidden beneath an extremely time-honoured veneer. Since her turn of face to needless violence and savagry, she has been adept at putting on a facade of kindness and modesty, tricking people into believing that she was, and still is, a simple and sincere woman. Only a few know that she has a dark side, mostly due to the fact that her powers are nefarious in nature. Fewer still see the truth; they dare not speak of it. To the outside world, Seikō is a gentle medical giant who spends time personally overseeing the responsibilities that has been given to her. She enjoys tea and tending the large garden at the centre of her dojo grounds. Many students come to visit her as she works within the flowers, never knowing that she secretly judges them, ruminating on their inferiority and lack of respect. Instead, they see a kind smile from a gentle old woman.


Minamo (水面; Water surface): Minamo is slightly longer than an ordinary katana, and resembles a ōdachi. The tsuba is in the shape of a hexagon, and the handle is pale blue. Instead of tying it to her obi, Seikō has her assistant Mai carry the blade for her, or in times of conflict she carries the blade over her shoulder by a rope strap.  The blade of the weapon takes up two-thirds of its breadth and boasts a fine silver finish and a wickedly sharp edge, which includes both sides of the last foot of the weapon. This dual-edged portion of the blade allows for swiping cuts and spear-point thrusts that most ōdachi aren't capable of.

Healing Hot SpingsSeikō needed to find a way to prolong her fights, and simple medicine wasn’t enough. By studying the effects of cell mitosis, she created this water in the hope that it could assist in her never-ending search for battle. By submerging the injured beneath the waters of this spring, their body's cell division by forcibly stimulated by proteins, which reconstructs all organs and tissues making up the human body over time. The technique itself does not regenerate the old cells; rather it hastens the creation of new ones through division. This water can heal simple injuries like cuts and bruises, to more major ailments like severed limbs and massive blood loss dependent upon how long they are submerged for. However, a body's cells can only split a certain number of times in a lifetime, and by speeding up this process, those healed by this water have shorter natural life spans (albeit not by much), making it a last resort.

Powers & AbilitiesEdit

Master SwordswomanSeikō’s personal specialty is sword fighting, particularly her mastery in the art of Kendō. She is said to know all 8,000 of the world's schools of swordsmanship. Her skill level in swordsmanship is stated to be equal or even superior to the combat oriented swordsmen Silvers Rayleigh, as she as she gained the upper hand for a part of their fight. It is painfully common for her to use her skills with kenjutsu to render an opponent unable to fight, cutting their nerves or dealing near-lethal damage, only to lord it over them that they were beaten by an old woman. She is not opposed to leaving such victims to perish slowly from their wounds.

  • Hitotsume: Nadegiri (一つ目・撫で斬り, The First: Killing Stroke): A precision cut of extreme force and speed which can slice through large, multi-story high opponents. The opponent is killed with one swift slash so precise, they are not even aware of until after it has taken place.

Physical Combat: Seikō is deceptively strong, have to break bones and send enemies flying with powerful strikes. However, due to her old age, she cannot fight of physically more impressive opponents.

  • Tesshō (鉄掌, Iron Palm): An open palm strike which can effortlessly smash bones and stone.

Hot Spring Water Manipulation: Seikō can call forth the water of her specialized hot spring and manipulate its movement and temperature as she desires. Despite having no real offensive capabilities, she uses this water to heal and restore “competent” foes in order to sate her thirst for battle. She often leaves this water on the ground of the battlefield, and when needed, she springs it up in a similar fashion to jaws biting down. She heals and restores them to their previous condition, ready to be slaughtered again

  • Same Kama (サメかま; Shark Bite): Seikō can send small torrents of water towards foes/allies in the shape of sharks that bite onto wounds and health them at a distance. These sharks can move great distances and as shot similar to missiles, allowing for successful ranged healing.

Medical Expert: Though she originally learned how to heal as a way to prolong her fights, Seikō has become very knowledgeable on health related matters. She has brought members of her crew back from various degrees of near death, and has reattached limbs and transplanted organs without causality. She is known to be highly proficient in conventional healing techniques and herbal healing. Her personal speciality is surgery.


  • Her name 精巧 歯並び (Seikō Hanarabi) translates to “Elaborate row of teeth”, fitting with her shark motive.
  • Chokhmah is a Sephirot with two faces, which can represent both sides of Seikō’s personality, the outer layer being a warm old woman and the true deep layer being a bloodthirsty barbarian. It also represents wisdom, something which Seikō has accumulated over her many years and reflects as acting advisor for Regulus.
