Does Muzan have a favorite demon? Despite the fact that Muzan. is always shown to have disdain for his creations, Muzan does in fact have a favorite. On that list is Naki, made due to a convenient blood demon.
Despite being the Progenitor of Demons in Demon Slayer: Kimetsu no Yaiba, Muzan Kibutsuji generally feels little more than disdain toward his creations. He has a few favorites among the Kizuki such as Rui (Lower Five), Gyutaro (Upper Six) and Akaza (Upper Three).
The only Demon he despises the most is the Upper Rank Two: Doma.
Later it was revealed that Muzan in fact considers Gyokko to be one of his favorite Upper Ranks due to his pots, with him greatly liking to the artistic skill he puts into them and the high price he gets by selling them.
1) Kokushibo
Kokushibo stands at Upper Rank 1 in the Twelve Kibuki. He is the only demon to have a breathing style in the Demon Slayer series. In fact, Muzan views him as more of a business partner and one of his closest allies.
Akaza is an upper-rank-three Demon and one of the most faithful minions of the Demon king Muzan Kibutsuji.
With his blood, Muzan can turn others into demons and seems like an unstoppable foe. However, the demon king seems to fear one thing: Tanjirou's hanafuda earrings. A look into Muzan's past reveals that only one man ever came close to killing him.
Yoriichi Tsugikuni was the first Demon Slayer and also the one who invented Breathing Techniques in the first place. Yoriichi was born with the Demon Slayer mark and prowess in swordsmanship. His powers were beyond comparison as he defeated Muzan once and had him on the verge of death until he managed to escape.
Her background as a courtesan coupled with her beauty meant that she would serve as a great and reliable source of income for Muzan, which is why the Demon King decided to be tolerant of her apparent stupidity.
Since Muzan favored Gyutaro so much, he chose to incorporate the latter's sister Daki as well. The demon king believed that she was the only tool that could be used to control Gyutaro. However, he deemed Daki weak and believed she was the prime reason for her brother's death.
Doma is always smiling and acts very friendly, but this cheerful, caring nature is simply a facade. He states that he cares for his fellow Upper Moons and even cries when he learns that Akaza died, though, in fact, he doesn't feel anything for them. Even when he was human, Doma didn't feel any type of human emotion.
Muzan Kibutsuji (鬼舞辻無慘, Kibutsuji Muzan) is the main antagonist of the Demon Slayer: Kimetsu no Yaiba fantasy action manga and anime series. Muzan is the powerful Demon King, who has the ability to inject his victims with blood that allows him to convert them into more demons.
it's so satisfying to see muzan still so scared of yoriichi, even centuries later. yoriichi has always left muzan with these horrific scars. despite not killing him, you have to give it to yoriichi, he might have given muzan a life more painful than death.
Enmu was one of the demons serving under Muzan, the first of his kind as well as the Demon King. They first met when Enmu was a human and Muzan consumed his guts.
Daki is faultlessly loyal to Muzan to the point at which it's almost obsessive. She drops her usual prideful demeanor around him and will act very meek when talking to him, seemingly transfixed by his prescience.
Nakime was favoured highly by Muzan, due to her ability being very convenient. Nakime is the only Upper Moon to have died by Muzan's hand.
The only two people she really cares for are Muzan Kibutsuji and her older brother. She shows deep respect for Muzan Kibutsuji immediately falling into a bow when he appears. Although she cares and loves her brother she is seen insulting and blaming him at times when things aren't going well.
Despite losing his memories, Akaza was noted to have subconsciously retained his strong feelings for Koyuki, this is seen where Doma noted that Akaza absolutely refused to kill and eat women during his hundreds of years as a Demon, despite his obsessive desire for more strength and power.
Curse of Kibutsuji
The curse prevents Muzan's name from being spoken aloud, and any who do will meet a horrible demise. One demon, Susamaru, faced this reality when battling Tamayo. Susamaru accidentally shot Muzan's name aloud, attempting to defend his honor with her mind clouded.
Muzan Kibutsuji's main weakness is sunlight, as seen when Gyōmei destroyed his head and he still couldn't manage to regenerate it. He tried to overcome this by devouring Nezuko, but that failed. He also has a weakness to Nichirin Blades, as they are the only way to kill him.
Muzan can detect the locations of his demons and can also read their thoughts. However, Nezuko and Tamayo are the only exceptions in the entirety of Demon Slayer, over whom Muzan has no control.
Kokushibo was the final Upper-Rank to die during Demon Slayer's "Infinity Castle" arc. Muichiro, Genya, Sanemi Shinazugawa and Gyomei Himejima fought together against Kokushibo, though Muichiro and Genya were no match for him and were killed.
14) Muzan Kibutsuji (over 1000)
Being a demon, Muzan is capable of living for many, many years. However, unlike other demons that have aged over hundreds of years. Muzan is well over 1000 years old.
Moreover, Tanjiro's appearance somewhat resembled Tsugikuni. So the only reason Muzan is afraid of Tanjiro is because of the Hanafuda earrings he possesses, which acted as a reminder of his downfall.
Gyomei used his weapon to hold him back while Sanemi, Giyu, and Tanjiro used their Breathing techniques to attack him. With the collective efforts of every member of the Demon Slayer Corps present there, Muzan turned to dust as sunlight came in contact with his body.
