How Strong Is Kokushibō (Compared to Other Demon Slayer Characters)?

In the world of Demon Slayer, the Twelve Kizuki were an organization made up of a group of twelve Demons who pursued the goal of finding the Blue Spider Lily. The organization was created and led by Muzan Kibutsuji. One of the members of this group was Kokushibō, who held the rank of Upper Rank One. Kokushibo was the second most powerful Demon, directly after Muzan, and was more powerful than the other Demons, and in this article, we will tell you a bit about his powers and abilities.
The article is going to be divided into two major parts. The first one will represent Kokushibō’s powers and abilities, while the other one will be a short comparison of Kokushibō’s powers and abilities to the powers and abilities of other characters, divided into several subsections. These will not be detailed analyses, just brief comments so you can understand Kokushibo’s position in the Demon Slayer lore.
Kokushibō’s powers and abilities
Kokushibō demonstrated great physical prowess by effortlessly raising a massive blade several times heavier than a typical katana and attacking it continuously at astounding speeds without pausing or exerting any effort. It can be assumed that Kokushibō had physical strength greater than or equivalent to higher rank three Akaza, a demon who can break the earth with his bare fists, since he absorbed more blood from Muzan Kibutsuji than Akaza. Kokushibō has developed into the second-strongest sword fighter ever, after his younger twin brother, Yoriichi Tsugikuni, after spending more than 400 years practicing and perfecting his swordsmanship techniques and considerably enhancing his physical abilities even further.
Kokushibō had incredible speed, probably much exceeding that of all the other Kizuki, as evidenced by the fact that he severed Akaza’s limb before the latter even understood what had happened. He often demonstrated his incredible speed. He could easily outperform Muichiro’s techniques at first, moving so quickly that it appeared as if he had teleported. Kokushibō’s speed, according to Muichiro, was in a different dimension than his own. Despite having his arm severed just as he arrived, Kokushibō could ” teleport” to the area where Genya was shooting him with his shotgun before the shots could reach him. He then quickly severed his second arm and body, giving the impression that he was not even moving.
Like other Demons, Kokushibō can heal his wounds without any trouble. Still, because he is one of the twelve Demons that make up the Twelve Demonic Moons, his healing happens considerably faster, displaying his immense power. In addition to his physical form, Kokushibō can regenerate his katana, which is forged from his flesh and blood. Similar to what happened with Akaza, his regeneration evolves to a point where he can reconstruct his head, approaching Muzan’s level of evolution.
He can make and control dozens of razor-sharp blades in the typical crescent moon form from his own body thanks to his Blood Demon Art, the Crescent Moon Blades, which complements his earlier fighting style, Moon Breathing. They can be either brilliant yellow or bright blue in hue and are thought to have been formed from his blood.
Kokushibō’s strikes are incredibly unpredictable and difficult to predict because these crescent moon swords constantly change in every aspect, including their shape and size. The swings of his blades are incredibly lethal and dangerous because of the Blood Demon Art, which considerably increases the effectiveness of his methods. Getting around his Blood Power is challenging because of how unstable it is.
How powerful is Kokushibō compared to other Demon Slayer: Kimetsu no Yaiba characters?
In this section, we will compare Kokushibō to some other strong Demon Slayer: Kimetsu no Yaiba characters. These are going to be brief comparisons whose main goal is to give you a general idea of his powers and abilities.
Kokushibō vs. Muzan
Muzan is the most powerful of all Demons and the creator of all the Demons that came after him. His weaknesses are the same as those of the other Demons, but his powers and abilities far surpass those of any other known Demon in the series. Using his powers, he has turned numerous people into Demons and has organized the most powerful ones in the Twelve Kizuki. Kokushibō was not the first Demon Muzan created, but he was by far the most powerful one, which is why he was ranked first among the Kizuki. Still, while Muzan was more powerful than Kokushibō, he respected him and feared him in some aspects, which is why Kokushibō had a special status among the Kizuki.
Kokushibō vs. Dōma
Kokushibō , as the Upper Rank One, was essentially the second-strongest Demon after Muzan. Kokushibō, Yoriichi’s brother, requested Muzan to convert him into a Demon so he might become stronger and immortal. He is an extraordinarily talented swordsman and is familiar with the Moon Breathing Style. Since the Twelve Kizuki were arranged in a hierarchy, Kokushibo was the strongest, making him the strongest among Dōma’s rivals. While Dōma was not the kind to regard or fear Kokushibō, it is clear that he was aware of his advantages, and there is no question that Doma would fall short against Kokushibō in a fight.
Kokushibō vs. Akaza
Kokushibō was undoubtedly, more powerful than Akaza. Akaza was the third among the Kizuki, and while he did not fear either Doma or Kokushibō, he was aware that both of them were more powerful than him. Kokushibō effortlessly reached and sliced Akaza’s hand off when the Kizuki were summoned to Muzan’s castle, scolding Akaza for his inappropriate behavior. Akaza dared not fight him because he knew that Kokushibo would strike him down with ease, swearing that he would kill him later when he became more powerful. So, yes, Kokushibo is more powerful than Akaza.
Kokushibō vs. the remaining Twelve Kizuki
As the Upper-Rank One, Kokushibō was the second-most powerful Demon after Muzan and the strongest of the Twelve Kizuki. In actuality, this meant that Kokushibō was able to defeat every member of the group who was still present, and that was not actually disputed. He was significantly more powerful, and given what we know about the power dynamics between Akaza, Doma, and Kokushibō, we may infer that Kokushibo’s power advantage over the surviving Kizuki is even greater, meaning Kokushibo would destroy them with ease.
Kokushibō vs. Tanjiro Kamado
Well, this is an intriguing one. Initially, there is absolutely no doubt that Kokushibō would have been able to kill Tanjiro in a matter of seconds; the difference in power was, indeed, so significant. But, as time passed, Tanjiro gathered more experience and became an exceptionally powerful Demon Slayer. If you add to that the fact that Tanjirō also learned the Sun Breathing Style later on (by remembering the Hinokami Kagura), we can only conclude that Tanjiro has gotten much stronger, but he never became the strongest.
He surpassed Akaza and was somewhere around Doma’s level, but he never really reached Kokushibō’s level, and in a direct one-on-one clash, Kokushibō would definitely be superior to Tanjiro and would defeat him with relative ease, although it wouldn’t be wholly one-way fight.
Kokushibo vs. Muichirō Tokitō
We always pick one specific Hashira to compare with a member of the Kizuki, and in Kokushibō’s case, we picked Muichirō, as the two of them were actually related. From an objective standpoint, we have to confirm that Muichiro was indeed a powerful fighter, but as the fight between them showed, Kokushibō was far superior and had no trouble dealing with Muichirō alone. And while Muichirō did defeat Kokushibō, it was only after three other Demon Slayers came to his aid in the fight.
Kokushibō vs. the remaining Hashira
This is a very versatile category, depending on whom Kokushibō would fight. A combination of Hashira would definitely be enough to subdue him, but individually, he would be able to defeat most, if not all, of them. The only one who would have a chance, surely, is Gyomei, and there is a possibility that Obanai could also be a match for him, but Muichiro, and even Giyu, would lose in a one-on-one fight; we can also add Sanemi and Mitsuri to the list. As for Tengen, Kokushibo would definitely be able to defeat him easily, especially with the latter losing his arm. Kyojuro Rengoku would also be a potentially strong opponent, but we would put him in the same category as Muichiro.
Kokushibō vs. Zen’itsu
Zen’itsu was able to defeat Kaigaku, but we’re certain that he would not be able to defeat the Upper-Rank One. And while Zen’itsu is certainly not to be underestimated, that much is true. He simply lacks the power, experience, and versatility to fight Kokushibō. Kokushibō has, on numerous occasions, demonstrated that he is a brutally powerful fighter and a tactical genius with unpredictable skills, and while Zen’itsu is certainly not weak, he is not even near the level of Kokushibō’s powers. This is why we are certain that Kokushibō would not have too much trouble facing Zen’itsu in a one-on-one fight.
Kokushibō vs. Inosuke
Everything we’ve said about Zenitsu can also be applied to Inosuke. Inosuke is physically stronger than Zenitsu, and he has a more versatile set of skills, but this is not nearly enough to defeat Kokushibō. On top of that, his tactical skills are far inferior to Kokushibō’s in every way imaginable. Inosuke is not stupid, but he approaches the fight without thinking, actually, and that is simply not good enough against an opponent who is as powerful as Kokushibō. Kokushibō and Inosuke never fought, but had they, there is absolutely no doubt that Kokushibō would easily deal with him in a direct clash, regardless of Inosuke’s durability.
