Of course.

appearance

Kokushibo was a Demon who maintained his human features despite having devoured countless people for 400 years. He maintained a series of quite unusual characteristics: he was a man of tall stature, pale skin tone, and an athletic, muscular build; His hair was long and black with burgundy edges [6], held by a long ponytail that reached almost to the height of his lower back [5]. On his face, he possessed a series of flame-like marks that covered the left area of ​​his head and the right side of his neck; These marks were, in his time as a human, his Hunter Mark. Kokushibo's most emblematic feature and, in turn, one of his most sinister hallmarks were his three pairs of eyebrowless eyes[5] which had a yellowish color to their irises and a red sclera divided into segments. [6]. In the eyes of the center, the numbering of him is located as the Superior Moon One identified with the kanji of First crescent (壱上弦,, Ichi Jōgen?) Indicating his dominant position within the Superior Moons. As for his clothing, he wore a kimono with purple and black patterns with a white haneri (undergarment of a Kimono), a black hakama, and a white obi belt. He possessed a katana made from his own flesh and bones, which was completely decorated with eyes on the cutting blade, on the Tsuba and the Tsuka [7] [8]. The guard was also covered with flesh [5] and eyes to completely increase the degree of his peripheral vision. After Sanemi and Himejima were able to decapitate him, Kokushibo managed to regenerate his head, transforming his body into a completely grotesque version of himself, with several fangs emerging from his mouth, a pair of horns growing out of his head, and several sharp appendages.[9]

personality

Kokushibo was a secretive being shrouded in absolute mystery. At the meeting of the Higher Moons, he proved to be punctual, respectful of the rules [5] and placed high value on the hierarchy of the Twelve Demonic Moons [7]. He was also humble, as he did not hesitate to admit his failure or complain about any difficulties, rather than acknowledging the strength of his opponent. He has shown a strong sense of loyalty towards Muzan Kibutsuji, and most of his actions were carried out for the sole purpose of fulfilling Muzan's goals [2]. Despite exhibiting an outward reserve of character and humility, he was also quite cold: his words could be harsh, especially when rebuking people. His threats are nothing short of cruel and overwhelmingly serious, and he demands absolute obedience. He has a complex relationship with his human past. He shows some warmth towards his descendant, Muichiro Tokito, praising his abilities and resolve [2], and insists on turning Muichiro into a demon to save his life. At the same time, he refers to Muichiro and his abilities as the natural result of the transmission of "cells" from him [8]. As a result, it is unclear whether he has any true attachment or whether it is the result of disproportionate narcissistic pride. Seeing the two demon-slaying brothers, Sanemi Shinazugawa and Genya Shinazugawa, makes him nostalgic[8]. Fighting Sanemi reminded him of dueling an ancient Wind Pillar to improve his abilities [10].

personality

Kokushibo was an extremely strong swordsman, being largely considered the second strongest Demon in the series behind only Muzan Kibutsuji and holding an important position of hierarchy within the Twelve Demon Moons. Being one of the oldest Demons, his combat experience is overwhelming. Having killed many pillars over the centuries, it has allowed him to develop highly efficient fighting techniques to combat Demon Hunters. His vast experience allows him to take on two experienced pillars and easily match their level, easily deciphering their abilities despite only facing them once. Being a user of breathing-based techniques, he possesses great levels of strength and reflexes that were enhanced thanks to his physiology as a Demon. With these qualities he was able to face on equal terms a pillar of the caliber of Gyomei Himejima who was considered the strongest pillar of his generation[15]. Even when Gyomei and Sanemi awakened their hunter marks that increase their physical capabilities beyond their limits[13], Kokushibo had no problems getting to their level and easily surpassing them[14]. Transparent World (透すき通とおる世せ界かい,, Sukitōru Sekai?): By possessing a Hunter's Mark, Kokushibo is able to use this extrasensory ability with which he can guess his opponent's next move, see the inside of their body and be able to attack their weak points.

Demon Skills Regeneration: Like all Demons, Kokushibo can regenerate his wounds without any problem, however his regeneration is much faster being one of the twelve Demons that make up the Twelve Demonic Moons, giving clear demonstration of his incredible power. Kokushibo's regeneration is not only limited to his body, but also to his katana which is made from his flesh and blood. As with Akaza, his regeneration reaches a level of evolution close to that of Muzan, being able to reconstruct his head. Demonic Blood Techniques (血けっ鬼き術じゅつ, Kekkijutsu?)

skills

Crescent Moon Blade Creation: It is revealed that during his past as a human, he harbored a huge resentment of spite and envy towards his younger twin brother, Yoriichi Tsukiguni, due to the natural talent and abilities he had since birth. These feelings of jealousy and contempt eventually intensified even further upon seeing his brother grow older and having survived said age despite awakening his Demon Slayer Mark that would supposedly condemn him to death at the age of 25. [11] However, despite this anger he held towards his brother for the difference in abilities they had, it was shown that he still loved Yoriichi despite tearing his corpse apart after he died, keeping as proof, the carved wooden flute he made for him as a memento of his memory for years to come expressing genuine regret for the path he chose. [12] In his duel against Gyomei Himejima, his banter suggests a fear of the idea of ​​death. When Gyomei's marks appear, Kokushibo preemptively mourns the loss of a talented fighter and urges him to become a Demon to continue honing his skills. He seems genuinely surprised when Gyomei vehemently rejects his offer and calls his mentality pathetic.[13] Probably as a result of his inferiority complex and immense desire for strength, Kokushibo is fearful of the possibility of suffering defeat[9], so much so that he becomes increasingly aggressive and agitated when cornered, evidence of which is the degree of aggressiveness in his attacks when he is in that situation and the use of his demonic power[14]. During his battle with the pillars, he realizes the high price he had to pay for the strength he so desired, becoming a hideous monster far from his idealized dream of a strong samurai like his brother, symbolizing how much his deep ambitions and resentment have deformed him in the worst way.

In addition to his own Moon Breath, being a Demon, Kokushibo can also make use of Demonic Blood Techniques. In his specific case, he can generate blades of different sizes that resemble crescent moons which emerge with each attack made [16]. The blades are believed to be created from his own blood, varying mainly in their coloration which goes from a yellow tone or a bright blue [17] [18]. The size of the blades can vary as well as their length and speed making his attacks totally difficult to dodge as well as having a very wide range allowing him to corner his opponents quite easily making them practically unpredictable and without an established pattern [19]. This Demonic Blood Technique makes his attacks more powerful turning each cut made into an extremely deadly one for his victims. Apparently, Kokushibo can also make use of these blades without needing to have his katana unsheathed or perform any cutting movement [20]. The volatile nature of this Demonic Blood Technique causes even the most experienced Demon Slayers to have serious difficulty trying to avoid this attack which is made clear when Sanemi states that if it weren't for his years of experience dealing with Demons, he wouldn't have been able to defend himself against these attacks [21]. Kokushibo's Demonic Blood Technique appears to have a secondary ability that 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 carries his crescent moon blades [22]. Kokushibo appears to be able to control said slashes to a certain extent, increasing their range and shape to attack his target in ways impossible under normal circumstances. When he distorted his katana, Kokushibo's Demonic Blood Technique would be able to control the shape and range of his sword slashes.
