Menacing Aura: 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 and temporarily made Muichiro Tokito, a Hashira who has faced and defeated an Upper Rank on his own, lose the will to fight and caused his body to tremble uncontrollably. [56] [57] Fighting Style [ ] It is revealed that as a human, Kokushibo harbored an immense sense of envy towards his younger twin brother for his natural talent and incredible abilities. These feelings of jealousy and contempt only became stronger upon seeing his brother become a peerless warrior of unmatched caliber among even the Demon Slayer Corps, with none of the Hashira coming close to his level of strength. This envy peaks when he discovers that Yoriichi was still alive and in old age, despite the curse of the Demon Slayer Marks supposedly killing him before he turned 25.

As the highest ranking member of the Twelve Kizuki, Kokushibo is an extraordinarily powerful demon, second only to the Demon King Muzan Kibutsuji himself. He has battled countless Demon Slayers and has amassed vast experience and knowledge over his near 500-year long life. His abilities have been refined to the highest level as he is not only a master of Total Concentration Breathing, but also a marked individual who has gained access to the Transparent World, as well as the demon that possesses the highest concentration of Muzan's blood in the organization. [12] 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 [29] and right shoulder [30] effortlessly. After being decapitated by two marked Hashira, Kokushibo is able to regenerate his entire head and successfully conquered death from a decapitation via Nichirin Swords, [31] a feat considered impossible for demons and only accomplished by two other demons: Akaza and the Demon King himself. [32] 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. [31] In regards to Akaza) " Akaza's presence is gone. He has fallen. Akaza... weren't you going to defeat me? A path had open for him to attain further heights but he renounced it himself. How exceedingly weak." [55]

He becomes a grotesque monster, far from his idealized vision of becoming the strongest samurai like his brother, highlighting how his ambitions and resentment have twisted him. To himself) " The ugliness of not admitting defeat even though they took my head, chopped me up and crushed me. Living in disgrace. Have I lived 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 miserable creature because I didn't want to die? No. Yoriichi... I just wanted to be you." [79] Tenth Form: Drilling Slashes, Moon Through Bamboo Leaves ( 拾 ( じゅう ) ノ 型 ( かた ) 穿 ( せん ) 面 ( めん ) 斬 ( ざん ) ・ 蘿 ( ら ) 月 ( げつ ) , Jū no kata: Senmenzan - Ragetsu ?)
