Summary

  • Muzan's power over demons stems from creating them through his blood, allowing him to control them with ease.
  • Demons fear betraying Muzan due to his ability to read their thoughts, making it easy for him to punish any disloyalty.
  • Muzan uses fear, manipulation, and promises of power to maintain control over demons, ensuring their loyalty through rewards and consequences.

In the world of Demon Slayer, Muzan Kibutsuji is recognized as the king of all demons. All the demons are extremely loyal to him and fear his anger. Muzan is the first demon and has turned thousands of others into one.

Throughout the series, we see Muzan treating other demons like absolute trash and not caring about their lives at all. Yet all the demons remained fearful of him and obeyed his orders. Even the most powerful of demons, like Kokushibo, Akaza and Doma never go against his wishes, which makes one wonder why Muzan holds so much power over them in Demon Slayer.

Why Are Demons Loyal To Muzan?

The Terror Of The Demon King

The biggest reason demons are so terrified of Muzan is because he created them all and, in a way, he controls them. He was the first demon ever, and he started the cycle of demons by using his blood. Whenever he wants to transform a human into a demon, he injects his blood into them. This act doesn't just make them demons, but also gives them enhanced strength, regeneration, and powerful Blood Demon Arts.

Muzan's blood forms a direct link with every demon which allows him to read their thoughts. He knows every plan and move the demons are going to make, which makes it super easy for him to control them. So in case anyone is even thinking about betraying Muzan, he will know immediately and finish them off in a second.

Using Fear As A Weapon

Muzan is superior to every other demon in terms of power. He can take out even the strongest of demons easily. We see this throughout the series when he disposes of lower moons if they fail in their tasks without thinking twice. Muzan also uses manipulation on demons like Daki and Akaza.

It is true that many demons follow Muzan out of sheer terror but some demons consider Muzan as their ultimate savior. Another scary thing about Muzan is that he has placed a curse on demons. Any demon who even speaks of his name or tries to reveal any information about him suffers major consequences. This happened to Susamaru, who accidentally uses Muzan's name during a conversation, which results in his insides getting torn apart by three demon arms.

Do not delude yourself into thinking you have free will. Your thoughts, your actions, see them all - Muzan

Muzan has also promised demons a lot of power and immortality if they follow him. This is why demons are always trying to please Muzan and become his favorite to get all the power in the world. Muzan can give humans the gift of immortality.

He can also give them the power to regenerate any part of their body, which makes them extremely difficult to kill. They also get rapid healing, which is why they are able to go up against the best of demon slayers and defeat them easily.

The Twelve Kizuki’s Loyalty

The reason why the Upper Moon are considered the strongest of demons is because they are the most loyal. They move up the ranks the more they contribute to Muzan’s ultimate plan.

You exist only because of me. Without my blood, you are nothing - Muzan

In return, they receive more blood from Muzan, making them powerful. So the upper moons are constantly trying to rank up by proving their loyalty to Muzan and for this, they are willing to go to any extent.
