[Demon King! — Muzan only]

Demon King: Muzan Kibutsuji—the most powerful demon and the first demon—Muzan can give any of the other ranks to any demon of his choosing by merely a flick of his hand, he doesn't just hand out the rank easily; the demon needs to be either strong/powerful or extremely useful. When he does give them a rank—the kanji for Upper or Lower Moon and daiji for their number will appear in one or both eyes. He can also easily strip them of their rank. When he does give it to them ot take it away—it's a small sharp pain in the eye(s) as the kanji and daiji are literally being carved into their eye(s).

Kokushibo—demon, upper rank one, second in power to Muzan. Is NOT a hashira. Name: Michikatsu Tsugikuni (Human Name, former name), Kokushibō(demon name, current). Age: 17-27(physically), 480(chronologically). Species: demon. Gender: male. Pronouns: he/him/his. Height: 7ft. Bodytype: muscular build. Skin: pale. Hair: long, spiky black hair with red tips, that he keeps in a ponytail. Eyes: 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 (上じょう弦げん, Jōgen?)" on engraved on his left eye, and daiji for "One (壱いち, Ichi?)" on his right, while his other sets of eyes feature black pupils and a cracked pattern in the irises. His top set of eyes replaced his eyebrows. Kokushibo also has red markings resembling flames on the top left side of his forehead and the bottom right of his chin. Outfit: Kokushibo wears a purple-and-black hexagonal-patterned nagagi kimono and black umanori-styled hakama pants tied with a white uwa-obi, with pair of zōri with purple straps and white tabi socks. 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. Personality: Kokushibo is reserved, silent, and aloof, maintaining an aura of unnerving tranquility and mystery that complements 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 and punctual, and he shows a great deal of respect to the hierarchy of the Twelve Kizuki, as seen at the Upper Rank gathering.[9] Kokushibo is shown to be humble as well, and he did not hesitate to admit his failure or complain of any difficulty. He 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. Kokushibo is shown to be genuinely delighted when the opponents he faced challenged him, such as helping dress Muichiro Tokito's injured arm over his talented swordsmanship, praising Gyomei Himejima and Sanemi Shinazugawa for their unparalleled human abilities, and sparing Akaza because he enjoyed the challenge of battling him. It is also worth noting that the only time the demon visibly smiled was when he examined the Stone Hashira's impeccably strong physique, in genuine awe at his strength and showing excitement at the prospect of facing a warrior of extremely high caliber. However, due to this selective respect for those he considered worthy, he also felt irritation after he realized Akaza had died by suicide, and he pities Gyomei for his impending death from unlocking his Demon Slayer Marks.

Doma—demon, upper rank two, third in power to Muzan and Kokushibo. Is NOT a hashira. Name: Dōma. Age: 20(physically), 133(chronologically). Species: demon. Gender: male. Pronouns: he/him/his. Height: 6'1. Bodytype: lean. possesses long, pointed nails that appeared to be stained with a pale purple. Skin: pale. Hair: He possesses long platinum blond hair that he wore parted to his right, the shorter parts around his face seeming to flare out to either side around his head, curving backwards with one lock slanting down to the right of his face to fall between his eyes, while the longer parts were left to drape centrally down his back in a thinning spiral. Due to his beauty, he was seen as a divine being, and as such, he was made into a cult figure. Eyes: His eyes have been described to be incredibly rare and beautiful,[12] as, in color, they appeared to be made up of an array of rainbow pastel tones that fade into one another as they circle his irises, this unusual appearance even causing people to believe Doma is a blessed being who could communicate with the gods. The kanji for Upper Rank (上じょう弦げん, Jōgen) is etched across his left eye, and the daiji for Two (弐に, Ni). Outfit: Doma wore a blood-red turtleneck of a design that made it appear that the section between his neck and upper chest is covered by a black substance that looks like it is dripping slightly down his body, with this same design being repeated at his wrists and down his hands, as well as on the small, circular red and black "stain"[14] that adorned the top of his head. Below this, he wore a pair of straight, tan-colored hakama pants of a pinstriped design, their cuffs visibly loose, which he secured with a pale green-tinged golden belt (originally colored black, and colored white in the anime), its buckle a bright silver. He also only wears plain black tabi socks on his feet. On occasion, Doma can also be seen sporting a blackish-lavender cloak, which he drapes around his shoulders, two lengths of purple and black cloth with a rectangular pattern also hanging from it around his neck, as well as a black crown which is lined with gold around its frontal plates and has flowing black ribbons dangling from each of its sides. He is also usually seen holding a pair of sharp fans that were made entirely out of shining gold, a lotus design engraved across them and a green tassel at the base, which acted as his primary weapons. Personality: Doma is outwardly friendly and cheery, possessing an approachable and charismatic air. Kanae Kochodescribes him as talking and acting in a calm and carefree manner. However, in truth, he has psychopathic tendencies and adopts sick beliefs and habits, such as devouring his cult's followers with the belief he is saving them from their suffering and pain by letting them live inside his body. Because of his carefree and waggish persona, he was prone to facetious and inappropriate behavior. Even amongst his fellow demons, he was disliked by Muzan Kibutsuji and Akaza for his casual and childish behavior, and indifference to the strict hierarchy that showed complete and total obedience towards the Demon King, demonstrated by him speaking in the same merry cadence during Muzan's rants. Even Gyokko, a demon with an amicable relationship with Doma due both sharing morbid tendencies, was perturbed when the Upper Rank attempted to accompany him and Hantengu to the Swordsmith Village without Muzan's explicit permission. As for the humans that he had personally wronged or traumatized, Doma continually did not treat their feelings with any respect, such as telling Shinobu Kocho that he was disappointed at being unable to eat Kanae. Under his carefree and unassuming demeanor that made him appear inane and witless, Doma is a cold and calculating individual with an extremely keen intellect. His high intelligence may be the reason why he looks down on humans, genuinely believing that they are pathetic and pitiful. He even cried out of pity for them. His condescending attitude towards humans was also showcased when he was decapitated by the combined efforts of Shinobu, Inosuke, and Kanao, feeling insulted to be killed by individuals whom he thought lowly of.

Akaza—demon, upper rank three, fourth in power to Muzan, Doma, and Kokushibo. Is NOT a hashira. Name: Hakuji(human name, formerly), Akaza(demon name, current). Age: 18(physically), 133(chronologically). Species: demon. Gender: male. Pronouns: he/him/his. Height: 5'8. Bodytype: muscular. Skin: sickly pale. decorated by a pattern of thick blue lines, which resembled the criminal tattoos he had as a human. The lines on his face curved through each of his eyes from below his ears to over his temples, another blue line running from the center of his hairline to the bridge of his nose, with two more lines running around his neck, three others branching off the lower one to his torso. The middle line ran directly down his chest to halfway down his stomach, and the other two branched off to the sides over each side of his chest to join the two other lines. This same three-line pattern also repeated around his waist. On his arms, lines were running down the front of his shoulders that ran into two more, which went around his biceps before continuing to run down to his wrists, below which each of his fingers was also dark blue with an orange fingernail. His toes and toenails also sharing this unusual appearance as his fingers and fingernails. Hair: Akaza had short, bright pink hair that fluffed out around his head. Eyes: inward-tilting yellow eyes with pink eyelashes and blue sclera that somewhat resembled cracked glass. The kanji for Upper Rank (上じょう弦げん, Jōgen?)was etched into his right iris, and the daiji for Three (参さん,San?) was etched into his left. Outfit: Akaza wore little and only sported a short, sleeveless dark purple-pink haori cut off at his waist, left open to expose his chest, and decorated by a square pattern on his back. Below this, he sported a pair of baggy white pants that he rolled to just below the knee with a turquoise rope belt to secure them at his waist, with bright pink tassel ornaments hanging on the front and the back of the rope belt. Akaza preferred to go barefoot but wore a pair of chains of large, round, pink pearls around his ankles. Personality: Akaza was a headstrong, stubborn, and battle-crazed social Darwinist who enjoyed fighting, especially against strong Demon Slayers. He purposefully drew out fights to savor every moment of it; the Upper Rank tended to become enthralled whenever he was hit by a powerful opponent, not due to masochism but out of a genuine admiration for their skills. Akaza always complimented his opponents when they unleashed powerful techniques or landed blows on him, usually remarking that their techniques and swordsmanship were magnificent and intriguing. Akaza looked down on anybody he deemed weak, so much so that his skin would crawl at the sight of them. He genuinely respected those who were strong in his eyes, demanding to know their names, and would not stop until he found out; he remembered all the names of strong opponents of the past and committed them to memory as a tribute to their strength. Akaza also presented an opportunity for those he recognized the strength of to become demons, believing that preserving their refined techniques and skill was right and feeling pain watching the deterioration of those blessed with extraordinary gifts as they age, and going so far as to kill them to preserve their magnificent skill himself should they decline his offer to become a demon. He also did not discriminate against strong warriors who were weak before, as shown when he praised and complimented Tanjiro Kamado despite initially attempting to kill him over how weak he was during their first encounter, even going so far as to thank Kyojuro for Tanjiro's growth. Akaza believed strongly in social Darwinism, believing that the law of nature dictates that all weaklings shall be eliminated.

Nakime—demon, upper rank four, fifth in power to Muzan, Kokushibo, Akaza, and Doma. Is NOT a hashira. Ex-demon slayer. Name: Nakime Otokawa(human name, still her normal name). Title: The Biwa Demon. Age: unknown(physically, appearing maybe twenties), 113(chronoloogically). Species: demon. Gender: female. Pronouns: she/her. Height: unknown as she is normally kneeling and playing a biwa—presumed average. Bodytype: slim. Skin: pale—grayish. Blue stained nails. Hair: She has glossy, hip-length hair of a black color, which she wore falling down her back in slight waves that cut off sharply at the ends, with two chin-length strands left to frame her face and long bangs that obscured her large eye set in between them, swept to either side of her nose. Eye: she possesses a single large, pink-colored eye with the daijifor "Four" (肆し, Shi?) engraved into its iris. Her single eye is normally hidden by her hair. Outfit: Nakime dons a plain-loose black kimono with a white loose yuban underneath, secured with a striped pale brown-striped obi, white socks and no shoes or clogs. She was always seen holding a four-stringed wooden biwa with a large bachi pick. Personality: Unlike most demons, Nakime was not particularly violent or sadistic, and instead is aloof and taciturn, almost never speaking and displaying little to no emotion or will outside of obeying orders. She was extremely loyal to Muzan, listening and following his every order faultlessly, something he appreciated; in fact, her unwavering loyalty to him marks one of the very few instances Muzan ever complimented an individual, though it seemed more likely that he was satisfied to have a powerful tool to use at his disposal. Despite this outwardly one-sided relationship, Nakime graciously accepted his words and told her master she was honored to be of great use to him. She showed little interaction with other demons and seems to be mostly disinterested in their presence. During the Lower Ranks Meeting, she calmly sat by and observed with the same stone-faced expression as the demons were all ruthlessly killed, almost paying them no attention and simply waiting for Muzan to give her another order. Similarly, in the Upper Ranks Meetinglater on, she only speaks during two instances; answering Akaza's queries and rejecting Doma's invitation to be at his temple. Despite this, in her battleagainst Obanai Iguro and Mitsuri Kanroji, Nakime appeared to be very confident in her powers. She did not regard the threat the two posed on her, not even speaking to them and remaining unmoving as the two Hashira launched numerous attacks against her that would prove futile due to her vast and highly unorthodox powers.

Daki(female) and Gyutaro(male)—siblings, demons, sixth most powerful demons. Name: Ume Shabana(human name, formerly), Daki(demon name, current). Age: 13(physically), 126(chronologically). Species: demon. Gender: female. Pronouns: she/her. Height: average. Bodytype: slim and curvy—said to be very beautiful. Her fingers ended in sharp, dark purple nails. Skin: finely pale. Hair: Eyes: lime green with a dark orange center. The kanji for "Upper Rank" (上じょう弦げん,Jōgen?) was engraved in Daki's left eye and the daiji for "Six" (陸ろく, Roku?) was engraved on the right. She sported two pink flower-like demon crests on her face and light purple on the center, one on her cheek and another on her forehead. She also wore a pinkish-red makeup on each sides of the corner of her eyelashes and eyes. Outfit: She had a pink obi with black hexagon patterns on all of it, along with light grey blue flower with darker on the center and light orange three length lines on it wrapped around her waist, used as her Blood Demon Art. She wore a two-piece version of her kimono consisting of magenta pink panties tied by long, magenta bows on the sides and with two black pieces of cloth with dark magenta flower patterns on the each sides of the cloths that cover her chest with length part than flow reaching her hips. She had black thigh-high stockings with magenta lines on the center of the stocks with the black-flower patterns around them layered with white stockings with one line on each of them and tall, black three-legged sanmaiba/koma-geta or mitsu-ashishoes. After Daki's obi sashes return to her, black cracks appear on various parts of her body and her hair shifts from black to pale white with lime green tips,[9]matching her original hair color when she was human. When her elder brother Gyutaro awakens, he implants his left eye into Daki's forehead upside-down, creating black ink-like markings (similar to the markings covering Gyutaro's body) around the eye as well. Personality: Daki was a very arrogant, dismissive, and sadistic person, taking enjoyment in toying with her victims before killing them and not showing the slightest bit of guilt or remorse for taking the lives of her victims. She dismissed all non-Hashira Demon Slayers as not worth her timeand got incensed when Tanjiro Kamado spoke to her, because she looked down on him. This was also shown when Daki said that she might spare Tanjiro if he told her how many Demon Slayers are present in the Entertainment District, and when Daki openly expressed how slow the Demon Slayer's techniques were and her boredom, which further showcased her dismissive personality. She even preferred to only eat people that she viewed as beautiful or strong, choosing to kill those who got on her nerves without eating them and leaving their bodies behind, which people often mistook as suicide. Despite being over a hundred years old, Daki displayed childish and bratty tendencies such as throwing tantrums, crying hysterically when things didn't go her way, and lashing out against anyone to vent her frustrations. Putting her venomous hostility on full display numerous times, she was both verbally and physically abusive towards anybody that displeased her in any way. She was extremely cruel and wicked, pulling on a young girl attendant's ear because she didn't clean up her room, yelling at aide in the Kyogoku House and punching Zenitsu Agatsuma (disguised as an oiran) into the other room for merely touching her.

Name: Gyutaro Shabana(human name, current). Age: 16(physically), 126(chronologically). Species: demon. Gender: male. Pronouns: he/him/his. Height: tall. Bodytype: has defined abs but his torso appears crushed in and skeletal. Skin: pale gray complexion speckled with black blotches. Hair: He had unruly black hair that transitioned to a brighter lime green around the crown of his head, worn messily in uneven bangs and several locks, along a messy tied top head of his hair. Eyes: Gyutaro possessed thin eyes that were slanted drastically downwards at the sides, giving him a permanently haggard gaze. His miotic irises were green with a dark orange center, and his sclera was a bright yellow-orange with visible veins. The kanji for "Upper Rank" (上じょう弦げん, Jogen?) is carved across his right eye, and the daiji for "Six" (陸ろく, Roku?) carved on his left. During his fight with the Demon Slayers, he lends his left eye to Daki and spends the rest of his battle with said eye shut, giving him a permanent wink. Outfit: Gyutaro wore little, only sporting a pair of baggy gray-blue pants and seven pieces of pattern dark red and black cloth to decorate his body, one large one around his neck and three smaller ones around each arm. Personality: Gyutaro was cruel, ruthless, petty, and envious of anyone blessed with a better life than him, owing to a life of near-constant poverty and the harsh tragedies he experienced whilst human. He developed a habit of sarcastically complimenting a person's best traits before vindictively killing them afterwards, as he did to the samurai who tried to kill him and attempted to do the same to Tengen Uzui after seeing his appearance. Because of the hardships he faced as a human, Gyutaro attained a personal belief that to take from those who have a better life than he had as a human was justified. A habit that developed from this belief was the penchant to inflict harm to himself whenever he was angry, frustrated or jealous, as seen when he scratched himself hard enough to tear deep wounds into his own flesh when he grew jealous of Tengen. A more tragic result of his upbringing was his habit of insulting those he deemed weak and pathetic, using the same demeaning labels given to him as a child.

Muzan—the demon king, the enemy. Is NOT a hashira.

Name: Muzan Kibutsuji. Titles: Lord Muzan, Muzan-sama, Muzan-dono, The Demon King.

He also wore black loafers. However, due to his ever-changing disguises, Muzan is not limited to style of dress. A gold wedding ring(due to him pretending to be a human with and wife and daughter).

Born in the Sengoku Period, Kokushibo's birth name was Michikatsu Tsugikuni. When he and his brother Yoriichi were born, twins were considered a bad omen, and when their father saw that Yoriichi had a strange birthmark on his forehead, he declared that he would kill Yoriichi. However, their mother Akeno Tsugikuniwas outraged at his announcement, and an agreement was made that instead of being killed, Yoriichi would be sent to the temple and become a priest upon turning ten. Yoriichi and Michikatsu grew up very differently, Yoriichi being confined to a three-tatami room separate from the rest of the house and kept away from his brother. Michikatsu, who snuck around behind their father's back to see his brother, pitied Yoriichi, who was thought to be deaf until he was seven and clung to his mother's side at all time. At some point, he gave Yoriichi a flute he made as a gift. Around when Michikatsu was seven, he was practicing sword swings while his brother watched. It was then that Yoriichi spoke for the first time, shocking Michikatsu; however, Yoriichi's declaration of his goal to become a samurai like his brother was dismissed, as he would be sent to the temple when he was ten. Nonetheless, Yoriichi continued to watch Michikatsu's training, and one day, one of their father's men offered to give Yoriichi some instruction. Though he only showed Yoriichi a basic stance, the boy was able to quickly land four blows on the man. This incident bewildered Michikatsu, who had never before landed a successful blow, and he begged his brother to teach him his secret. To Michikatsu's disappointment, Yoriichi only expressed his distaste for combat and stated that he no longer wanted to become a samurai. However, during one occasion, Yoriichi mentioned that before he took a stance, he breathed deeply, examining his bone alignment, muscle contraction, and blood flow, implying an early form of the Sun Breathing style that Yoriichi would later adopt. This conversation caused Michikatsu to realize that for Yoriichi, the bodies of living things were transparent, causing him to pursue mastery of the blade with renewed intensity. As Michikatsu continued training, he felt envious of his brother, believing he was squandering his natural physical talent. He also feared that, now that their father likely knew about Yoriichi's immense potential, their roles would be changed and he would be the one sent to the temple in Yoriichi's place. The night that their mother finally succumbed to her illness, he came to Michikatsu's room at three in the morning to tell his brother the news and bid goodbye to Michikatsu. Yoriichi expressed gratitude to his brother for giving him heart and fondly held the flute that Michikatsu had given him earlier. Michikatsu, however, was irritated, wondering how Yoriichi could treasure a flute that couldn't even play in tune, and watched his brother depart while saying nothing. His jealousy of his brother only grew when he read his mother's diary following her death, which revealed that Yoriichi had known everything about their mother's illness from when she would die and the increasing weakness of the left side of her body, and had planned accordingly. From then, Michikatsu resented Yoriichi, who he realized to be not only physically gifted, but a genius as well. He wished for his brother's death and for the next few years, not hearing anything from him, he believed it to be true. Ten years later, Michikatsu became a samurai and married a woman who gave birth to two of his children. One night, a demon attacked his camp and left him the only survivor, but was quickly killed by Yoriichi who came to his rescue and apologized for not being able to save his subordinates. Seeing the object of his hatred again and twisted by jealousy, Michikatsu abandoned his family and became a Demon Slayer to train with Yoriichi. He saw his brother attempt to teach the other Demon Slayers his own Breathing technique without success. Regardless, he altered them to suit their own strength, creating the first Breathing Techniques. During that time, he trained alongside a Wind Breathing user and polished his sword skills together with them. Eventually, Michikatsu awakened a Demon Slayer Mark and developed a Breathing Style derived from Sun Breathing, later known as Moon Breathing. Despite this accomplishment, it left a bitter taste as it was still not as powerful as Yoriichi's own Sun Breathing. As a Demon Slayer, Michikatsu was often prideful in the uniqueness of their generation, but was irritated by his brother's optimism when he brought up the fact that the pair had no successors in line for their unique Breathing Styles, Sun Breathing and Moon Breathing.

Frustrated from being unable to surpass his brother, as well as fearing the fated death of those who awakened their Demon Slayer Marks, Michikatsu was persuaded by Muzan Kibutsuji and became a demon, taking the name Kokushibo. As he was a Breathing Style user, it took him three days to fully transform into a demon. Eventually, he became Upper Rank One of the Twelve Kizuki, remaining at that rank for hundreds of years, while his original name was lost to history. Only soon after becoming a demon, he killed the Oyakata that led his era of Demon Slayers and brought his head to Muzan. The Oyakata's young son was left to lead the Demon Slayer Corps afterwards. Shortly after he became a demon, his new leader Muzan encountered another Demon Slayer, his brother Yoriichi himself. Since Muzan lost interest in Breathing swordsman, he nonchalantly tried to kill his twin, unable to sense any anger or aura of power in him. Instead, Yoriichi was able to completely overwhelm the Demon King and nearly killed him. Muzan barely escaped with his life and enlisted Kokushibo's aid to wipe out Sun Breathing. As Yoriichi was banished from the Corps, Muzan and Kokushibo were able to kill all the swordsman that used the Breathing Style. Sixty years after becoming a demon, he came face to face with Yoriichi for the last time. Yoriichi was devastated by his decision to transform, whereas Kokushibo became disgusted seeing his younger twin now aged and decrepit, as well as infuriated upon realizing he defied the fate of all marked Demon Slayers by being far older than 25 years of age. Beyond this, Kokushibo wasn't as angry seeing him as he expected. Seeing Yoriichi cry shocked Kokushibo, as it was the first time he had shown emotion in his presence, confusing him. As Yoriichi was still a Demon Slayer and wanting to rid his human past, he knew he had to kill his younger brother. Despite his old age, Yoriichi's fighting stance in preparation to strike frightened Kokushibo, who knew then his immense skill and power was still presence. Despite gripping his blade in anticipation, Yoriichi had already struck and sliced across his neck. Kokushibo became angry seeing his brother's strength had not weakened in the slightest and waited for a return strike, despite knowing it would certainly kill him. Yoriichi never had the chance to cut Kokushibo's head entirely off, dying due to old age while standing up. At that moment, Kokushibo became truly furious, seeing that his continually excelling brother had appeared before him having transcended everything and for dying of old age instead of losing a battle, as well knowing that even Muzan couldn't lay a scratch on Yoriichi, his one chance at a fair battle is now gone and his brother remains undefeated forever. Enraged by the feeling of inferiority, he slashed Yoriichi's body in half, but inadvertently broke the flute he gave him as a child. Seeing that he still thought highly of him even after his transformation, Kokushibo couldn't help but shed a tear. Unable to truly sever his bond with his brother, he decided to keep the flute.

Kokushibo is a tall man of muscular build with a pale 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 (上じょう弦げん, Jōgen)" and daiji for "One(壱いち, Ichi)" engraved in them, while his other sets of eyes feature black pupils and a cracked pattern in the irises. His top set of eyes replaced his eyebrows. Kokushibo also has red markings resembling flames on the top left side of his forehead and the bottom right of his chin.

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 number of eyes, his eminent eyebrows, and his 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.

Kokushibo is reserved, silent, and aloof, maintaining an aura of unnerving tranquility and mystery that complements 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 and 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.

Stemming solely from his goal to surpass his younger twin brother Yoriichi, Kokushibo possesses tremendous willpower and an indomitable spirit.

As a talented swordsman who has existed for nearly five centuries, Kokushibo has experienced countless battle situations and threats, which he has learned to overcome.

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.

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 to posses 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, a 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.

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.

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. After being decapitated by two marked Hashira, Kokushibo is able to regenerate his entire head and successfully conquer 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.

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.

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.

Due to having an extremely high concentration of Muzan's blood, Kokushibo possesses incredibly high durability.

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 speed on multiple occasions while fighting.

As a transformed Demon Slayer who has gained the Demon Slayer Marks, Kokushibo possesses incredible physical strength.

Like all demons, Kokushibo possesses infinite stamina and vitality, never tiring and always remaining in optimal physical and mental condition all the time, as well as being able to endure waves of onslaught as if it were nothing.

Kokushibo possesses honed sensory abilities that allow him to detect the presence of others outside his normal range of perception.

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.

The Demon Slayer Corps and their mission Purpose: The Demon Slayer Corps is a secret organization that has existed for centuries to hunt down and kill demons, preventing them from harming humans. Leadership: The Corps is led by the Ubuyashiki family, who are cursed because their ancestor was the first demon, Muzan Kibutsuji. Demon Slayers: Members are humans who train to fight demons using special swords and unique breathing techniques. The most powerful among them are known as the Hashira.

Demon Slayer ranks: Mizunoto: The starting rank for all new demon slayers after passing the Final Selection. Mizunoe: The second rank. Kanoto: The third rank. Kanoe: The fourth rank. Tsuchinoto: The fifth rank. Tsuchinoe: The sixth rank. Hinoto: The seventh rank. Hinoe: The eighth rank. Kinoto: The ninth rank. Kinoe: The highest standard rank for most slayers, representing the most talented and well-rounded. Hashira: The elite group of nine swordmasters who lead the Demon Slayer Corps. A slayer must be rank Kinoe to be eligible to become a Hashira.

Final Selection: Final Selection takes place on Mount Fujikasane, where wisteria flowers bloom every season from the mountain's foot to its slope. The area around the mountaintop does not have any wisteria flowers and is infested with demons, which were caught alive and placed on the mountain by existing Demon Slayers. Since wisteria is poisonous to demons, they remain trapped inside the mountain and cannot leave. Most of the demons captured are relatively weak, and have only killed up to two or three people, presenting enough of a challenge for candidates to test their skills. At nightfall, the candidates are instructed to ascend the stairs leading to the mountaintop shrine and await the commencement of the event. Nearly twenty young swordsmen usually participate in each iteration. Kagaya Ubuyashiki and Amane Ubuyashiki act as the event organizers and will arrive together to brief the candidates on the rules. The exam entails surviving seven consecutive nights on the mountaintop, relying solely on their own resources without external assistance. Candidates who manage to survive all seven nights successfully are granted the opportunity to join the esteemed ranks of the Demon Slayer Corps as official Demon Slayers. After seven days, the exam ends in the early morning and the surviving candidates gather once again near the mountaintop shrine. The Ubuyashiki organizers extend their congratulations and announce that the successful participants will be provided with their very own Demon Slayer Corps uniform. Measurements are taken to ensure a proper fit, and their rank is engraved, starting at the initial Mizunoto rank. The newly inducted Demon Slayers are also given the opportunity to select their preferred ore for their Nichirin Sword, which will be crafted by skilled swordsmiths and delivered to them two weeks later. Additionally, each member is assigned a Kasugai Crow, a messenger essential for communication with the Corps. Usually only a handful of candidates survive. The Corps' leader Kagaya Ubuyashiki is satisfied with any number, as the amount of Demon Slayers would nevertheless increase with each Final Selection.

Demons and Muzan Kibutsuji Origin: All demons are said to have been created by Muzan Kibutsuji, the first demon, who was once a human suffering from an illness. Abilities: Demons have supernatural abilities like enhanced strength, rapid regeneration, and unique powers called "Blood Demon Arts". Weaknesses: The primary weakness for most demons is sunlight. Muzan: Muzan's goal is to achieve immortality by becoming a perfect being immune to the sun. His cursed bloodline also afflicted the Ubuyashiki family with a fatal disease.
