ADULT Anime – DEMON SLAYER Kokushibo Cosplay Costume

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.^[1] 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 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.^[27] 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 when Gyomei or Sanemi damaged it with their attacks.^[29][27] 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).^[30]

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^[31] and right shoulder^[32] 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,^[33] a feat considered impossible for demons and only accomplished by two other demons: Akaza and the Demon King himself.^[34] However, while the speed at which he regrew his head was far faster than the former, his regeneration after being decapitated became unstable, causing him to take on a monstrous visage.^[33]

Monstrous Transformation: After regrowing his head while battling Gyomei and Sanemi, 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 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.^[33] 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.^[20]

Demon Slayer Abilities

Demon Slayer Mark: Kokushibo awakened his Mark when he trained under Yoriichi.^[35] 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.
