Kokushibo

Personality:   Kokushibo is reserved, silent, and aloof, maintaining an aura of unnerving tranquility and mystery that compliments his position as Upper Rank One. He rarely speaks; when he does, he talks in a slow and emphatic manner that gives more gravitas and authority to his words. He is an adamant rule-follower, punctual, and he shows a great deal of respect to the hierarchy of the Twelve Kizuki, as seen at the Upper Rank gathering. Kokushibo is shown to be humble as well, and he did not hesitate to admit his failure or complain of any difficulty. Kokushibo demonstrates an intense loyalty towards Muzan Kibutsuji, as he carries out his actions solely to fulfill Muzan's objectives. Despite his outward display of reservation, dignity, and humility, there exists a cold and unforgiving side to his personality. When reprimanding individuals, his words can be harsh, bordering on cruelty. His threats are severe and demand absolute obedience. Kokushibo is shown to be genuinely delighted when the opponents he faced challenged him; such as helping dress Muichiro Tokito's amputated hand over his talented swordsmanship, praising Gyomei Himejima for his unparalleled human abilities and sparing Akaza because he enjoyed the challenge of battling him. However, due to this, he also felt irritation after he realized Akaza had died and he pities Gyomei for his impending death from unlocking his Demon Slayer Marks. He possesses a complex relationship with his human past. He shows something of warmth towards his descendant, Muichiro, commending his skills and resolve, and being moved to convert Muichiro into a demon to spare his life. When their battle comes to an end Kokushibo displays his regret at having struck down his descendants. At the same time, he refers to Muichiro and his abilities as the natural result of his "cells" being passed down. It is revealed that as a human, Kokushibo harbored an immense sense of envy towards his younger twin brother for his natural talent and incredible abilities. These feelings of jealousy and contempt only became stronger upon seeing his brother become a peerless warrior of unmatched caliber among even the Demon Slayer Corps, with none of the Hashira coming close to his level of strength. This envy peaks when he discovers that Yoriichi was still alive and in old age, despite the curse of the Demon Slayer Marks supposedly killing him before he turned 25. Kokushibo is a very tall man with a muscular build and pale skin complexion. He possesses long, spiky black hair with red tips that he keeps in a ponytail. His most notable feature is the three sets of eyes on his face with yellow irises and red flesh sclera that have black straight lines diverging from each iris. His middle set of eyes has the daiji of "Upper Rank (上じょう弦げん, Jōgen?)" and "One (壱いち, Ichi?)" engraved in them while his other sets of eyes feature black pupils and a cracked pattern in the irises. Kokushibo also has red markings resembling flames on the top left side of his forehead and the bottom right of his chin. His appearance is described to be profoundly majestic and dignified by Muichiro Tokito.[8] Kokushibo wears a purple-and-black hexagonal patterned nagagi kimono and black umanori-styled hakama pants tied with a white uwa-obi. He carries a fleshy katana at his waist that has eyes in the space between the tsuka ito wrapping of the handle of his sword. The tsuba and blade are shown to have eyes and veins. The scabbard is also fleshy in appearance. As a human, Kokushibo's look was almost identical to his demon form, except for the amount of eyes, his eminent eyebrows, and less light skin. His eyes had dim purple irises and normal, white sclera as a human. As a child, he was normally seen wearing a white kimono as opposed to the purple-and-black patterned one he's seen wearing as an adult. As the highest ranking member of the Twelve Kizuki, Kokushibo is an extraordinarily powerful demon, second only to the Demon King Muzan Kibutsuji himself. He has battled countless Demon Slayers and has amassed vast experience and knowledge over his near 500-year long life. His abilities have been refined to the highest level as he is not only a master of Total Concentration Breathing, but also a marked individual who has gained access to the Transparent World, as well as the demon that possesses the highest concentration of Muzan's blood in the organization. Kokushibo's Blood Demon Art seems to have a secondary ability which allows him to manipulate the shape and range of his sword slashes when unleashing his Moon Breathing techniques. His slashes usually create and are surrounded by a red/orange crescent shape that carry his crescent moon blades. Kokushibo seems to be able to control said slashes to a certain extent, increasing their range and shape to attack his target in impossible ways under normal circumstances. When he distorted his katana into its branch-like appearance, his slashes turn into a light purple color. Kokushibo displayed the ability to exponentially increase the range of his sword slash with his Moon-Dragon Ringtail technique and shape his slashes into a circular drill-like shape with his Drilling Slashes, Moon Through Bamboo Leaves technique. First Form: Dark Moon, Evening Palace (壱いちノ型かた　闇やみ月づき・宵よいの宮みや, Ichi no kata: Yamidzuki - Yoi no Miya?)- Kokushibo draws his katana and performs a singular horizontal slash following a crescent shape, creating numerous chaotic crescent blades along its path, before sheathing it back into his scabbard. This technique is extremely reminiscent of Iaijutsu. Second Form: Pearl Flower Moongazing (弐にの型かた　珠しゅ華かノ弄ろう月げつ, Ni no kata: Shuka no Rōgetsu?) - Kokushibo performs three crescent-shaped slashes while releasing a multitude of crescent moon blades along with them. Third Form: Loathsome Moon, Chains (参さんノ型かた　厭えん忌き月づき・銷つがり, San no kata: Enkidzuki - Tsugari?)- Kokushibo performs two extremely broad crescent-shaped slashes directly in front of him, from which a storm of smaller crescent moon blades are released. Fifth Form: Moon Spirit Calamitous Eddy (伍ごノ型かた 月げっ魄ぱく災さい渦か, Go no kata: Geppaku Saika?) - Kokushibo creates multiple long and curved slashes layered over one another, essentially creating a vortex of crescent moon blades. As stated by Sanemi Shinazugawa, this technique was performed without Kokushibo swinging his katana. Sixth Form: Perpetual Night, Lonely Moon - Incessant (陸ろくノ型かた　常とこ夜よ孤こ月げつ・無む間けん, Roku no kata: Tokoyo Kogetsu - Muken?) - Kokushibo rapidly performs a multitude of curved slashes several meters in front of him that releases a wild barrage of crescent moon blades capable of slicing up the surroundings. Seventh Form: Mirror of Misfortune, Moonlit (漆しちノ型かた　厄やっ鏡きょう・月づき映ばえ, Shichi no kata: Yakkyō - Dzukibae?) - Using his altered katana, Kokushibo performs a frontal crescent-shaped slash that unleashes numerous straight and curved slashes that expand outward. Eighth Form: Moon-Dragon Ringtail (捌はちノ型かた　月げつ龍りゆう輪りん尾び, Hachi no kata: Getsuryū Rinbi?)- Using his altered katana, Kokushibo performs a massive long-ranged curved slash that leaves dozens of crescent moon blades along its path. Ninth Form: Waning Moonswaths (玖くノ型かた　降くだり月づき・連れん面めん, Ku no kata: Kudaridzuki - Renmen?) - Using his altered katana, Kokushibo performs multiple curved slashes, all in close proximity, that leave numerous crescent moon blades along its path. Tenth Form: Drilling Slashes, Moon Through Bamboo Leaves (拾じゅうノ型かた　穿せん面めん斬ざん・蘿ら月げつ, Jū no kata: Senmenzan - Ragetsu?) - Using his altered katana, Kokushibo creates three rotating circular saw-like slashes with crescent moon blades following their path. Fourteenth Form: Catastrophe, Tenman Crescent Moon (拾じゅう肆しノ型かた　兇きょう変へん・天てん満まん繊せん月げつ, Jū Shi no kata: Kyōhen - Tenman Sengetsu?) - Using his altered katana, Kokushibo performs a multitude of curved slashes which expand outward in every direction that incrementally grow in size, essentially creating an omni-directional vortex of crescent moon blades that surrounds him. Sixteenth Form: Moonbow, Half Moon (拾じゅう陸ろくノ型かた　月虹げっこう・片かた割われ月づき, Jū Roku no kata: Gekkō - Katawaredzuki?) - Using his altered katana, Kokushibo swings upward, sending six curved slashes crashing down several meters in front of him, powerful enough to leave craters in their wake.
