Kimetsu no Yaiba: This is the only demon Muzan hates.

It could be one of the most powerful demon moons of all, but that’s not why it’s the favorite

Muzan Kibutsuji is the main antagonist of Kimetsu no Yaiba (Demon Slayer), as his power as the king of demons makes him a powerful adversary, as well as being able to turn other people into fearsome beasts. In a way, he is not only the leader of the organization, but a “father” to the demon moons. However, there is one of them that he repudiates for personal reasons, Doma, one of his three most powerful subjects.

This information comes from a side story written by the creator. Kimetsu no Yaiba (Demon Slayer), Koyoharu Gotouge. But why does he hate him so much? One of the first reasons Muzan Kibutsuji hates Doma is revealed in a meeting with the living upper demon moons, after Gyutaro and Daki passed away. Doma had been responsible for recruiting this pair, he had also failed in his mission to search for the Blue Spider Lily or Ubuyashiki.this plant that would help Muzan to be able to live under the sun.

Despite this, Doma does not seem very sorry for his “failures” and, unlike other demons in Kimetsu no Yaiba (Demon slayer), Muzan does not feed on him and, moreover, maintains his position of giving him the freedom to do whatever he pleases like running his house of worship called Eternal Paradise Faith, where he feeds on his subjects. According to the upper demonic moon, it is because of this that he has become more powerful, as he has fed on women and pregnant people to increase his attack to devastating levels.

This top rank two demon moon taming fighting level is probably what keeps him safe from Muzan’s murderous wandering eye. because he holds the dream that there will come a point to resist the light of the sun to consume him and become the most powerful being in this universe.

How did Muzan Kibutsuji become the demon king in Kimetsu no Yaiba?

Muzan’s great weakness for Taming in Kimetsu no Yaiba (Demon Slayer)

Let’s remember that Muzan Kibutsuji’s weakness, like that of the rest of the demons under his command in Kimetsu no Yaiba (Demon Slayer), is to sunlight, which sets them on fire and destroys them in an instant. The demon king never killed Doma because he couldn’t risk losing such a powerful demon, as he believed it possible that this demon could become strong enough to survive in sunlight, so killing it could have been detrimental to his own life..

In fact, At the end of the Swordsmiths’ Village arc of the manga, Muzan revealed that he never wanted to create other demons in the first place.. He did not plan to build an association of demons that would threaten the Japanese society of the Taisho era. The only reason he did it was in the hope that a demon would become powerful enough to resist the sunlight and live an ordinary life again. It is even worth remembering that Muzan Kibutsuji began his life as a demon thanks to a doctor who gave him the hope of extending his life a little more and recovering his health.


If Muzan were to consume a demon so strong that it survived sunlight, he would gain the power for himself and achieve his dream of becoming the perfect being. This is why his determination and his hatred against Doma is not reason enough to get rid of him, even though he killed most of the lower ranks. He may have done it so confidently because none of them could be powerful enough to resist sunlight or even come close to developing this ability. Doma, on the other hand, had too much potential to justify killing him just to get him to stop talking. Once Nezuko Kamado became immune to sunlight, Doma surely stood by for the inevitable conflict with the demon hunter corporation, in which this demon succeeded where even Akaza failed by killing one of the Hashira, Shinobu Kocho. At the end of the day, Doma’s potential outweighed his annoying personality, if only slightly..
