- Tsugikuni Michikatsu
- As the highest-ranking member of the demons, who are fundamentally man-eaters, he has committed countless atrocities. However, in terms of personality, unlike Kibutsuji Muzan and Douma, he is relatively normal within the Twelve Kizuki, alongside Akaza. [This is largely due to his upbringing, which, unlike most demons with unfortunate family backgrounds, was relatively free of worries except for his inferiority complex towards his younger brother.] He is extremely wary of any disruption to the hierarchy. As the highest-ranking member, he lacks camaraderie and, when he sees Upper Rank demons acting selfishly, he warns them that Muzan has arrived. When Douma provokes Akaza, who loses control of his anger and commits insubordination, Michikatsu warns him to have a replacement battle if he has complaints. He effectively manages the Upper Rank organization in place of Muzan, who has no interest in organizational management. Although he and Muzan are on informal terms, to the point where they use casual language with each other, he uses the honorific 'Lord Muzan' when mentioning him in front of others. This is a formal courtesy as Muzan is his superior, demonstrating how much he values order and discipline within the group, as well as his strict separation of public and private life. He also respects the honor of warriors and shows reverence to opponents who have reached the level of a master. He is a battle enthusiast who enjoys fighting strong opponents. He is usually almost emotionless, or more accurately, his emotions are not prominent because there is rarely anyone who can move them. However, when it comes to his battle-loving nature, he is no less so than Akaza. As mentioned later, when he met Gyomei, he was delighted, calling him a strong opponent after 300 years. Seeing his descendant Muichiro's elegant swordsmanship, his Mist Breathing, and his composure in immediately stopping the bleeding and preparing for battle after his arm was severed, he felt proud, saying he was indeed his descendant. He even asked Muzan to make him a demon and train him. Unlike Douma, who scoffed at Akaza's declaration that he would kill him someday, Kokushibo himself offers serious advice and encouragement, telling him to strive harder. Despite being the most serious among the Upper Ranks, he has a strong competitive spirit. This personality trait has carried over from his human days. His most striking physical feature is his six eyes, which give onlookers a chilling impression. They don't particularly enhance his vision or have special functions, but the occasional independent movement of his eyes suggests that his field of vision is at least wider than that of an ordinary person. In the past, tears were seen falling from the eye below his right eye.
