For those of you who have read the manga, you must already know about Kokushibo’s past. But for those of you who don’t know, Kokushibo was once a human named Michikatsu Tsugikuni.

He is a swordsman who is the brother of Yoriichi Tsugikuni. Michikatsu is frustrated because he cannot surpass Yoriichi and is afraid of death because he has awakened the mark.

Seeing Michikatsu’s weakness, Muzan offered him to become a demon so that he could live a long time and become stronger. Michikatsu accepted Muzan’s offer to become a demon and changed his name to Kokushibo.

2. Muzan’s Most Powerful Subordinate

Ever since Michikatsu became a demon and changed his name to Kokushibo. Muzan now has very strong subordinates. The reason for this is because Kokushibo used to be a swordsman.

In addition, since he was a child, Kokushibo or Michikatsu had been taught to wield a sword by his father. It’s no wonder that he’s so strong now that he’s an adult, let alone a demon with a very long lifespan. There’s no doubt that Kokushibo is very strong, even other upper moon demons can’t beat Kokushibo.

3. The Demon that Uses the Moon’s Breath

As we know, demons in Kimetsu no Yaiba can be defeated using Nichirin swords and breathing techniques. But uniquely Kokushibo who is a demon uses the moon breathing technique.

If Yoriichi was the one who created the Sun breathing technique, then Michikatsu or Kokushibo created the Moon breathing technique. The reason why he uses Moon breathing is because his body can’t use Sun breathing. Despite being a demon, Kokushibo continued to develop his breathing technique.

4. Losing because of being ganged up on

Although this Kokushibo is the strongest subordinate of Muzan, but still in the end Kokushibo was defeated by the current era Hashira. So in the final battle Kakushibo had to deal with Hashira Stone Gyomei Himejima, Hashira Wind Sanemi Shinazugawa, Hashira Mist Muichiro Tokito and Genya Shinazugawa.

Although Demon Slayer Corps struggled against Kokushibo, because Kokushibo’s technique was dangerous. But because they managed to awaken Mark, they were able to subvert Kokushibo. And interestingly enough, it turns out that Muichiro Tokito is a descendant of Michikatsu.


Thus the discussion about Kokushibo, the first-ranked upper moon demon in Kimetsu no Yaiba. After reading this article, what do you think of this Kokushibo figure? Don’t forget to keep visiting Dafunda.
