Demon Slayer: Kimetsu no Yaiba is a manga depicting the battle between demons and the Demon Slayer Corps that exterminate them. The leader of these demons is the charismatic and powerful Kibutsuji Muzan. Demons are far from united, and conflicts are constant, but the one thing they all agree on is that they follow and worship Muzan. Even the lower-ranking demons are so great that they are the source of fear. This time, we'll introduce you to the charismatic evil of Muzan Kibutsuji!
Muzan wields absolute control.

Muzan's leadership skills make even the Upper Rank members kneel in submission. His power is so overwhelming that even Upper Rank Four would be beheaded in an instant if he blurted out something uncertain in the middle of a conversation. Muzan only seeks unchanging, reliable information. After this, he gave orders to Hantengu and Gyokutsubo to confirm the uncertain information.
Muzan is handsome and stylishly dressed.

As the enemy boss, you might expect him to look as intimidating as the other demons, but he's actually surprisingly handsome. He also seems to have a penchant for fashion, as he's always seen out and about in stylish outfits. Of course, his hair is always perfect. Maybe he's surprisingly picky about that sort of thing (lol).
Muzan is also a master of mimicry (disguise)

Muzan's specialties include deceiving people through mimicry and disguise. If he so desired, he could even disguise himself as a young boy, like this one, from his usual adult appearance. Here, too, he's wearing stylish clothes and a stylish hairstyle... He seems to be living a pretty good life as a human.
He sometimes gets so excited that his mimicry falls apart...

While living as a human in the form of a child, Muzan receives news that Nezuko has overcome the sun. Muzan was so excited by the joy that he revealed his true nature and massacred the maids and others around him. Killing someone senselessly as a result of his joy and excitement... Even though he looks handsome, he's still a terrible villain.
For some reason, Muzan seems to have a penchant for cross-dressing.

Although he has a mean look in his eyes, he's a beautiful woman dressed in a beautiful kimono. This is Muzan in drag. It's unclear why he's cross-dressing, but for some reason, he appears before the lower-ranking demons dressed as a woman. The lower-ranking demons are confused, asking, "Who is this?" However, his voice seemed to be the same, and upon hearing it, he realized it was Muzan.
Even in drag, his power and cruelty remain the same.

The other Lower Rank demons were gathered together after hearing that Rui, the Lower Rank Five, had been killed. Muzan then told them that the Lower Rank demons were unnecessary. The lower-ranking demons couldn't help but interject. However, Muzan was enraged by the mere mention of a lower-ranking demon. He refused to allow any conversation other than answering his questions, and all but one of the lower-ranking demons were killed.
They finally found Ubuyashiki. There, they learned the truth.

The two have had a fateful relationship for over a thousand years. However, when Muzan finally finds Ubuyashiki, he feels no hatred. And what Ubuyashi tells him is the truth: they are of the same bloodline. In other words, Muzan is like an ancestor to Ubuyashiki.
If Muzan dies, all demons will be wiped out!?

If Muzan dies, won't all demons be wiped out? When asked this question, Muzan freezes, looking shocked for a moment, perhaps because Ubuyashiki has hit the nail on the head. If defeating Muzan would wipe out all the demons, then all they had to do was focus their attacks on Muzan without even bothering with the Upper Rank demons...but Muzan himself has already made some moves, so it seems things aren't going so smoothly after all.
The Final Battle!? The main forces of the Demon Slayer Corps are gathering around Muzan!

Muzan is weakened by Ubuyashiki's self-sacrificing suicide attack and Tamayo's almost selfless blow. Then, the Hashira and Tanjiro and the others gather together. Though the Hashira are scattered by Muzan's trap, the curtain rises on a direct confrontation with Muzan and the Upper Rank demons.

Muzan seems to have some strange hobbies, like being fashionable and cross-dressing, but he is truly a powerful man who can unite the demons. While he seemed cornered in the latest episode, it seems his battle with Muzan is still ongoing.
