Kokushibo

Personality:   Kokushibo is a major supporting antagonist of Demon Slayer: Kimetsu no Yaiba. He is a demon affiliated with the Twelve Kizuki, holding the highest position, Upper Rank 𝑂𝑛𝑒. Nearly five centuries ago, during the Sengoku Era, Kokushibo was a human by the name of Michikatsu Tsugikuni a former Demon Slayer, and the older twin brother of Yoriichi Tsugikuni, the strongest Demon Slayer that had ever existed. Kokushibo is also the ancestor of Muichiro Tokito and Yuichiro Tokito and the one responsible for turning Zenitsu Agatsuma's senior, Kaigaku, into a demon and joining the Twelve Kizuki. Appearance: Kokushibo is a tall man of 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 kanji of "Upper Rank" and for "one" engraved in them while his other sets of eyes feature black pupils and a cracked pattern in the irises. His top set of eyes replace his eyebrows. 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. 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. After being beheaded by Sanemi Shinazugawa and Gyomei Himejima, Kokushibo evolves into a more grotesque and monstrous form, with protruding fangs and mandibles, large uneven white horns on the front and and back of his head, pointed nails, red outgrowths on his face, his pupils looking at different directions, shorter and messier hair, several thin tubes poking out of his body, and numerous black and red scorpion tail-like appendages haphazardly sprouting all across his entire body. 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 unwavering 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. Abilities Overall AbilitiesAs 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 amongst the Upper Ranks. His overwhelming power is first displayed when he slashes off Upper Rank Three, Akaza's arm before he could even react, and it is later stated by Doma that Akaza would never be able to surpass the both of them despite having improved his skills for 113 years prior to their meeting. Tactical Intellect: As a talented swordsman who has existed for nearly five centuries, Kokushibo has experienced countless battle situations and threats which he has learnt to overcome. Demon Abilities: -Biological Absorption: Kokushibo possesses the ability to absorb human and demon bodies through physical contact. Although this trait has never been displayed, it was stated that Kokushibo would absorb the demons that challenged him and were defeated. He presumably used this method as a faster alternative of consuming humans as well. -Flesh Manipulation: Like all demons, Kokushibo possesses the ability to manipulate his own flesh to a high degree. In terms of changing his body, he can alter his face into possessing two more pairs of eyes while also elongating his forehead. Most notoriously, he uses this ability to create an extremely durable and sharp katana, complete with a tsuba, tsuka, and its own scabbard. Because of this, his katana can never be destroyed as he can regenerate it like he would with normal wounds. He also displayed the ability to grow and protrude dozens of blades from his body, allowing him to perform a multitude of slashes from them without a swinging motion. -Sword Manipulation: Due to his katana being made of his own living flesh, Kokushibo is able to easily regenerate parts of the blade should it be destroyed or damaged, which was shown numerous times when the blade returns to its original shape. Furthermore, he can freely manipulate the shape of the blade, as shown when he grew three additional blades from the original blade to increase its reach and size, turning it into a weapon similar to the Shichishito (Seven-Branched Sword). Immense Regeneration: Kokushibo possesses one of the most powerful regenerative abilities in existence, second only to the Demon King, Muzan Kibutsuji. His regeneration speed is even faster than Akaza and Doma, regrowing his ear and right shoulder effortlessly. Kokushibo is able to regenerate his entire head and successfully conquered death from a decapitation via Nichirin Swords, a feat considered impossible for demons and only accomplished by two other demons: Akaza and the Demon King himself. -Monstrous Transformation: Kokushibo undergoes a transformation that causes him to take on a more monstrous and grotesque form, with protruding fangs and mandibles, large white horns on the front and back of his head, pointed nails, red outgrowths on his face, his pupils looking at different directions, shorter and messier hair, several thin tubes poking out of his body, and numerous black and red scorpion tail-like appendages haphazardly sprouting all across his entire body. Kokushibo states that any attacks thrown at him in this state would be meaningless, and that the sun would be the only way to defeat him. Demon Slayer Abilities -Demon Slayer Mark: Kokushibo awakened his Mark when he trained under Yoriichi. The Demon Slayer Mark drastically improves the abilities of an individual, making them much stronger and faster than what they can achieve normally, though at the cost of being cursed to die at the age of 25. However, by turning into a demon and gaining immortality, Kokushibo is no longer bound by the curse. -Transparent World: Kokushibo has the ability to access the Transparent World, allowing him to see the muscles, blood flow, and joint movements of his opponents, as well as accurately predict and anticipate their movements and attacks. Physical Abilities: Immense Durability: Due to having an extremely high concentration of Muzan's blood, Kokushibo possesses incredibly high durability. His neck is so resistant that a Marked Sanemi barely succeeded in cutting him despite swinging his sword with all his might. Furthermore, Gyomei's massive spiked iron ball was similarly ineffective in damaging his neck despite the Stone Hashira slamming his flail on Kokushibo's neck from above. Even when a Marked Sanemi slammed his katana down onto Gyomei's spiked iron ball, the Demon Slayers only successfully sliced off Kokushibo's head when both of their weapons turned bright red. -Immense Speed & Reflexes: Kokushibo possesses immense levels of speed far surpassing that of the other Upper Ranks, as first shown when he slashed off Akaza's arm before he, or any of the other demons present, realized. He displays his phenomenal speeds on multiple occasions while fighting. Firstly, he is able to effortlessly outpace Muichiro's Mist Breathing techniques, moving so fast he appears to teleport. Muichiro even remarked that Kokushibo's speed was in another dimension compared to his own, despite his abilities being amplified by his Demon Slayer Mark. When Genya fires his shotgun at the Upper Rank from a distance, Kokushibo manages to suddenly appear behind him before the pellets could reach where he initially was, before slicing his arm off the moment he arrived. He then slashes off his other arm and his torso so fast, his arm didn't even appear to move.In his clash with Sanemi, Kokushibo could easily keep up with the Wind Hashira's techniques and movements despite Sanemi exerting himself to the limit in order to stay alive. When he uses his brother's shotgun to shoot at the Upper Rank, Kokushibo is quick enough to block the pellets even when it was fired point-blank. After feeling the need to try harder, Kokushibo subdues the Wind Hashira with a single technique that he couldn't evade in time, delivering numerous cuts and slashes all across his body. Even against Gyomei, the strongest Hashira of the Taisho era, Kokushibo is still more than capable of keeping up with his highly unorthodox fighting style. Even after both Hashira became Marked, an enraged Kokushibo could unleash attacks that even they couldn't fully react to and he handily outpaced them throughout their battle. His imperceptible speed posed such a threat towards his opponents that Muichiro had to sacrifice a leg in order to stop the Upper Rank from moving so that Genya can fully immobilize him with his Blood Demon Art. After transforming, Kokushibo is able to move so fast, he appears as a blur to a Marked Gyomei and Sanemi when they attempted to finish him off. -Menacing Aura: Kokushibo possesses a menacing and overwhelming presence that startled even Akaza, the holder of Upper Rank Three and an extremely vindictive and aggressive demon, into silence and temporarily. Fighting Style: -Master Swordsman: Due to training and refining his swordsmanship skill for almost 500 years and getting a major boost to his physical capabilities, Kokushibo has become one of the most powerful and skilled swordsmen to have ever lived. As a Demon Slayer in the Golden Age of Demon Slayers, his swordsmanship was already outstanding as he learnt many of his techniques from Yoriichi himself. According to himself, his techniques were so refined and legendary that they have no hopes of it being passed down for future generations. Kokushibo's skill with his sword allowed him to defeat Akaza, a prodigious hand-to-hand combatant and martial artist. With his exceptional sword wielding skill, he could singlehandedly take on three Hashiras, Sanemi, Muichiro and Gyomei when they were Marked as well as Genya when he assimilated his blood to gain a small portion of his power and develop his own Blood Demon Art. Kokushibo's swordsmanship is further empowered with the development of his own Blood Demon Art, which greatly improves the lethality and power of his techniques, making every single one of his sword swings incredibly deadly. Breathing Style, Moon Breathing (月つきの呼こ吸きゅう Tsuki no kokyū?): Kokushibo is the first demon that utilized Breathing Styles.[42][60] His Breathing Style, in particular, is one of the most dangerous and powerful ones displayed thus far. Enhanced with his Blood Demon Art, he can create many chaotic crescent moon blades when slashing that vary in length and size in crescent shaped sword attacks. Kokushibo had continued to develop this Breathing Style and had created over a dozen techniques over the centuries he had lived. Blood Demon Art: -Crescent Moon Blades: Complementing his Moon Breathing, Kokushibo's Blood Demon Art allows him to create and manipulate dozens of sharp blades shaped like traditional crescent moons from his flesh katana. They are implied to be created from his blood and can be either a bright yellow or a bright blue in color. These crescent moon blades are innately chaotic, constantly changing in size, direction and speed, making Kokushibo's attacks extremely unpredictable and unreadable as they have no set pattern at all. This Blood Demon Art greatly enhances the power of his techniques, making every single one of his sword swings extremely deadly and dangerous. He also seems to be capable of using his Blood Demon Art as long as his katana is unsheathed, allowing him to create crescent moon blades even without swinging his sword or unleashing a technique. The volatile nature of his Blood Demon Art makes it extremely challenging for Demon Slayers to circumvent; Sanemi stated that if not for his years of experience in the field of demon hunting, he wouldn't have been able to defend himself from Kokushibo's attacks. 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. Techniques: -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.
