Muzan Kibutsuji: The Demon King Afraid of Death.Part-2

In this part we will talk about the rest story of the Muzan Kibutsuji: The Demon King Afraid of Death.

The Powers of Muzan: Untouchable by All : Let’s put it like this – when compared to Muzan, any of the strongest Twelve Kizuki (Akaza – able to destroy buildings with his fists, Doma – creates blizzards with the movement of his fans, Kokushibo – can slash through the air faster than a marked Demon Slayer can see) Muzan is like a tornado throwing buildings around. to be clear, this is not just hyperbole. This really is Muzan’s power level.
Muzan’s main power is Biokinesis, which gives him full control of his entire body. He can change his appearance, including the structure of himself, and the way his flesh and organs look, as much as he wants to, in ways that the other demons can’t. This is the one ability that helped Muzan stay hidden from the Demon Slayer Corps for a thousand years. Muzan could look like a young lady or a child and also like a nondescript middle-aged man just about at will. For a thousand years, the planet’s deadliest creature roamed freely on Earth with humanity and no one realized it.

In combat, Muzan is a horrifying experience in every possible manner of the term. He was able to instantly unleash several attacks at once, killing multiple demon slayers on the spot, and was able to withstand the combined force of the five Hashira altogether. He created whip-like appendages from his body, at first from his back and later from his thighs after the demon slayers began attacking him successfully, and each was seven meters in length, traveling faster than most individuals could detect them.
Blood from this demon can cause instant cell damage/collapse upon contact, with only a slight touch. He has such strong regenerative powers, that the traditional way of killing a demon (by cutting off their head) has no effect on him whatsoever. The speed of his attacks was so fast that it forced Tanjiri into a state where he could not even see what The demon was doing, even though he was weak Paradise due to The use of an anti-aging drug.
He continued to be the most formidable presence in the building despite battling his last duel while his body was being rapidly aged by poison, which was taking away several years every minute he lived.

Yoriichi: For once, he met someone who gave him the creeps : Muzan Kibutsuji never knew what it meant to be afraid for nearly 1,000 years. Then he met Yoriichi. Yoriichi was a demon slayer many centuries ago who developed the sun breathing style, which is the strongest breathing style ever created and all the other styles of breathing are derived from it. Yoriichi’s battle with Muzan turned out to be the most one-sided battle of all time, from the perspective of Muzan. Not only did Yoriichi beat Muzan, but he also cut him into tiny pieces that made it impossible for Muzan to heal from.

To recover from the defeat, he barely managed to survive by splitting his body into approximately 1800 pieces and spreading it out. He then hid himself under the ground and regenerated himself for months. Since a thousand years had passed before they met one another, this was the closest that a being like Muzan had come to dying, and the event would continue to impact him for as long as he lived. Years after that, when Tanjiro wore the same earrings as Yoriichi and practised breathing method similar to Yoriichi’s, it sparked fear in Muzan’s body, which shows just how traumatized Muzan was by that event.
Also, this explains the reason why he hates the descendants of Sun Breathing and tries to wipe out its entire lineage. Not only does Muzan see Tanjiro as a threat, but he’s also determined to kill the last person that could remind him of the one person that has ever made him think that he’s not immortal.

The Final Battle, and how it happened:
Basically, when Muzan dies in the Infinity Castle arc, the circumstances of his death are almost poetic.
Through the fighting, Muzan alters his body by becoming a large fleshy cocoon, as a means to get rid of the poison that was turning him to a human being. He then emerges out of the cocoon as a much stronger and monstrous appearing creature, with jaws coming out of all over his body to eat Demon Slayers and to regenerate his own strength. Although coming close to death, even when he was trapped, even when he was being consumed by a drug that was killing him at a very accelerated pace, Muzan refused to give up. He would not stop changing. If he stops, it is as good as receiving the defeat. And to acknowledge defeat is to acknowledge death. And this was the only thing that Muzan could not do.

Ultimately it was the sun that made him die because it was the one thing he was afraid of and he tried for a thousand years to not become afraid of the sun any more. He almost made it, literally within seconds of getting out in to the daylight shade, and did not make it. And as a result all his hard work was for nothing. During the last moments of his life, to avoid facing the reality of who he had become, Muzan transferred his awareness to Tanjiro. In addition to being another attempt to survive, he wanted to leave his will and abilities behind. His attempt resulted in Tanjiro becoming a savage creature that was attacking according to the will of Muzan, i.e., to destroy the rest of the Demon Slayers. Even at the last moment, the only thing he was thinking about was surviving.
Muzan Is A Great Example Of A Good Villain In Anime Series
The reason why Muzan is an effective villain is because his reasons for doing things always seem rational, even when his actions become increasingly evil.

He started life as a terminally sick person, which is sad enough on its own. The fact that he became immortal was accidental also makes him sad. His pursuit of the BlueSpiderLily was originally about finding a cure for his illness. After becoming immortal through an accidental transformation, everything Muzan did (creating demons and killing DemonSlayers) was motivated by a basic human need (not dying).
Evil was not his origin, which is why it is tragic. The tragedy is that he spent a millennium (thousand years) looking for change yet continued to rely on fear for every year he was presented a chance to find his way out. He wasted his potential to learn and grow because he had more time than any human being could ever hope to have; yet, that whole millennium was spent running from something that he imagined.
