Height: 190 cm years: 480 weight: 93 kg Hair color: Black with Red tips eye color (he has 6 eyes): Gold with Red sclera

appearance:

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?)" 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. 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.

personality (character):

Kokushibo is reserved, silent, and detached, maintaining an aura of frightening calm and mystery that complements his position as the First Highest Rank. He rarely speaks, and when he does, he does it slowly and expressively, which gives his words more weight and authority. He strictly follows the rules and is punctual, and also shows great respect for the hierarchy of the Twelve Kizuki, which can be seen at a meeting of the Highest Rank. Kokushibo is also shown to be humble, he did not hesitate to admit his failures and complain about any difficulties. He demonstrates unwavering devotion to Muzan Kibutsuji, as he performs his actions solely to achieve Muzan's goals. Despite the fact that outwardly he is restrained, noble and modest, there is a cold and implacable side to him. When he reprimands, his words can be harsh, bordering on cruelty. His threats are harsh and require absolute submission. Kokushibo is genuinely happy when the opponents he fights challenge him, such as when he helps Muichiro Tokito bandage his amputated arm, praises Gemei Himejima and Sanemi Shinazugawa for their unprecedented human abilities, and spares Akaza because he enjoys fighting with him. It is also worth noting that the only time the demon visibly smiled was when he was looking at the immaculately strong physique of the Stone Hashira, feeling genuine awe at his strength and showing excitement at the prospect of coming face to face with a warrior of extremely high caliber. However, due to this selective respect for those he considered worthy, he also felt annoyed after realizing that Akaza had committed suicide, and he felt sorry for Homei for his imminent death due to unlocking his Demon Slayer Marks.

Capabilities:

As the highest ranking member of the Twelve Kizuki, Kokushibo is an extremely powerful demon, second only to the Demon King Muzan Kibutsuji himself. He had fought countless Demon Slayers and had accumulated a lot of experience and knowledge in his nearly 500 years of life. His abilities have reached the highest level, as he is not only a master of the full concentration breathing technique, but also a marked person who has gained access to the Transparent World, as well as a demon with the highest concentration of Muzan blood among the higher ranks. His incredible strength is first revealed when he cuts off the hand of Akase from the Highest Rank 3 before he can react. Later, Doma declares that Akaza will never be able to surpass both of them, despite the fact that he had been perfecting his skills for 113 years before they met. During the battle at Infinity Castle, Kokushibo easily defeated the Misty Hashira, Muichiro Tokito, an outstanding Demon Slayer who single-handedly defeated the Fifth Highest Rank and awakened his Mark of the Demon Slayer in the middle of the battle, Gekko. Later in the encounter, he easily chopped off Muichiro's arm before he could react, and caught his sword in flight before striking. Indomitable Will: Driven solely by the desire to surpass his younger twin brother Yoriichi, Kokushibo possesses tremendous willpower and indomitable spirit. Even though he was decapitated by Gemei and Sanemi, he forced his regeneration to develop and regrew his head because he did not allow himself to die until he reached his goal. Tactical Intelligence: As a talented swordsman who has been around for almost five centuries, Kokushibo has experienced countless combat situations and threats that he has learned to overcome. This manifested itself during his battle with the three marked Hashira and the enhanced Demon Slayer, where he was able to adapt to their unique fighting styles and tactics almost instantly upon seeing them.

Demon's Abilities:

Biological Absorption: Kokushibo has the ability to absorb the bodies of humans and demons upon physical contact. Although this trait was never shown, it was stated that Kokushibo would devour the demons that challenged him and be defeated. He apparently also used this method as a faster alternative to consuming people. Manipulating the flesh: Like all demons, Kokushibo has the ability to manipulate his own flesh to a great extent. As for changing his body, he can change his face by adding two more pairs of eyes and lengthening his forehead. Most famously, he uses this ability to create an extremely durable and sharp katana with a tsuba, tsuka, and its own scabbard. Because of this, his katana cannot be destroyed, as he can regenerate it, just like with normal wounds. He has also demonstrated the ability to grow and release dozens of blades from his body, allowing him to strike multiple times without swinging the weapon. It was only through his activation that Kokushibo was not only able to blow away Sanemi and Gemei, but also cut down Muichiro, Genya, the trees that Genya used in the Blood Demon Art to pin him to the ground, and the numerous pillars around. After being decapitated, Kokushibo greatly changed his body, taking on a more bestial and grotesque appearance, with growing limbs, thin tubes, sharp mandibles and horns. Incredible Regeneration: Kokushibo possesses one of the most powerful regenerative abilities, second only to the Demon King Muzan Kibutsuji. His regeneration rate is even faster than that of Akaza and Doma, and he easily regrows an ear and right shoulder.

Physical abilities:

Incredible durability: Due to the extremely high concentration of blood, Muzana Kokushibo has incredibly high durability. His neck is so strong that the Marked Sanemi barely managed to injure him despite swinging his sword with all his might. In addition, Gemei's huge iron ball with spikes also failed to damage his neck, despite the fact that the Stone Oyashra struck his flail at Kokushibo's neck from above. Even when the Marked Sanemi brought his katana down on Gemei's iron ball, the Demon Slayers successfully chopped off Kokushibo's head only when both of their weapons turned bright red. Incredible speed and reflexes: Kokushibo possesses incredible speed, far surpassing that of other High Demons, which was first demonstrated when he chopped off Akase's arm before either one or any of the demons present had time to react. He repeatedly demonstrates his phenomenal speed during the fight. Firstly, he easily surpasses Muichiro in the Mist Breathing technique, moving so fast that it seems as if he is teleporting. Incredible power: As a transformed Demon Slayer who received the Marks of a Demon Slayer, Kokushibo possesses incredible physical strength. He is able to split the earth just by stepping on Sanemi's sword, and he is able to wield a giant sword that is much heavier and longer than a regular katana and swing it continuously at incredible speed without resting or exerting much effort. After the transformation, Kokushibo was able to chop off Muichiro's arm with his bare hands like a blade. Unlimited stamina and endurance: Like all demons, Kokushibo has endless stamina and resilience, never gets tired and is always in optimal physical and mental condition, and is also able to withstand waves of attacks as if it were nothing. Even though his limbs and entire body pieces were repeatedly torn off and destroyed, he never once showed a single sign of pain or agony.

Supernatural Abilities:

Extrasensory perception: Kokushibo has honed sensory abilities that allow him to detect the presence of other people outside his normal range of perception, as shown when he dodged Zhenya's shots and appeared right behind him, despite Kokushibo looking in the opposite direction. Kokushibo also seems to be able to track the location of his peers around Infinity Castle, apparently since he no longer felt Akaza's presence when he died. Menacing aura: Kokushibo possesses a menacing and overwhelming presence that silenced even Akaza, the holder of the Third Highest Rank and an extremely vengeful and aggressive demon, and temporarily deprived Muichiro Tokito, Hashira, who single-handedly fought and defeated the Highest Rank, of the desire to fight, causing his body to tremble uncontrollably.

Quotes:

(Regarding Akaza) "Akaza's presence has disappeared. He's fallen. Akaza... Weren't you going to beat me? A path to further heights opened up before him, but he himself refused it. How weak he is." (Regarding Gemei Himejima) "Wonderful... Perfect physical form, brought to perfection... How long has it been since I last saw such a great swordsman? Perhaps 300 years?" (Regarding death) "Since Yoriichi died, a noble death will not visit me. Now that the greatest swordsman in the long history of the Demon Slayers has died... I shouldn't lose. Yes. I decided to keep winning... not yet... so ugly." (In response to Yoriichi Tsugikuni's statement about future generations) "Yoriichi... When you smiled, I couldn't help myself... but it always confused me. And when we were talking about the fact that different breathing techniques have no successors, you suddenly began to look at things with a strange optimism and smiled. In my vanity, I thought that only our generation was special. I was sick of disgust and irritation. What amused you so much?" [...] What's so funny about imagining such a future? Just the thought of losing makes me seethe with anger." (To myself) "The ugliness is not admitting defeat, even if they cut off my head, chopped me into pieces and crushed me. To live in shame. Have I lived for hundreds of years for this? Was I so afraid of defeat that I became a monster? Did I want to be strong, even if it meant eating people? Did I become this pathetic creature because I didn't want to die? No. Bricks... I just wanted to be you."
