Kokushibo to Muichiro Tokito before turning his attention to Genya Shinazugawa in True Feelings

Kokushibo (黒こく死し牟ぼう, Kokushibō?) 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 (上じょう弦げんの壱いち, Jōgen no Ichi?).[2]

Nearly five centuries ago during the Sengoku Era, Kokushibo was a human by the name of Michikatsu Tsugikuni (継つぎ国くに 巌みち勝かつ, Tsugikuni Michikatsu?),[3] a former Demon Slayer,[4] and the older twin brother of Yoriichi Tsugikuni,[5] the strongest Demon Slayer to ever live.

Kokushibo is also the ancestor of Muichiro Tokito and Yuichiro Tokito[6] and the one responsible for turning Zenitsu Agatsuma's senior, Kaigaku, into a demon and joining the Twelve Kizuki.[7]

Advertisement Appearance Kokushibo is a tall man with a muscular build and 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?)" 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. His appearance is described as 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, 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.

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.

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 back of his head, pointed nails, red outgrowths on his face, his pupils looking in 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 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 amputated hand 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.
