Akaza was also one of Muzan's favorite demons out of all his subordinates. The reason behind this is Akaza's extreme loyalty to his master. The Upper Rank Three demon was always sent away on special missions, something the Upper Rank 1 and 2 were often denied of.
Throughout his life as a demon, Akaza never felt any sort of awe, hatred or respect for Muzan, instead viewing him simply as someone who gives orders and himself as someone to carry them out. Muzan became fond of him, due to his loyalty, will to become stronger and gave him special permission to not eat women.
Every demon in the Demon Slayer respects the demon lord because of the fear he inflicts. Even Upper-Rank Three: Akaza got thrashed boasting about executing a Hashira, insignificant to Muzan as humans are frivolity in front of demons. Apart from that, Muzan doesn't hate Akaza because of his obedience.
As stated by Doma, that Muzan had tolerated and allowed Akaza's unique aversion to not eating or harming women and even only went as far as only dispatching him on special missions only, a privilege not even given to Upper Rank 1 or 2. He was one of Muzan's favorites since he was loyal and serious.
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).
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.
Muzan is displeased with Akaza's "accomplishment", declaring that one victory is meaningless until the entire demon slayer corps are destroyed and that Akaza failed to kill the other three Demon Slayers at the train. He punishes Akaza by making him bleed profoundly and dismisses him.
It was later revealed that Akaza's desperate and stubborn pursuit of strength was to heal his sick father and to protect the ones he loved and cared about, namely his fiancée Koyuki and his teacher Keizo.
Furthermore, Doma is regarded as the coldest and most obnoxious demon. He frequently behaves carelessly around Muzan, which he even hates. All these aspects, as well as Doma's lack of sincerity, irresponsibility, and complete maniac-like nature, fuel Akaza's hatred for him.
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.
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.
Who does Muzan regret killing? He shows his most human side to fans, wherein he admits to regretting murdering his doctor. He comments that had he been patient, the doctor would have cured him, and he would never have turned into a demon.
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.
Prior to becoming a demon, Akaza was a human named Hakuji, who lived during the Taisho period in Japan. He was a strong believer in the concept of justice and upheld a strong moral code. This code included a deep respect for women and a refusal to cause them harm.
Muzan retorts it was only one Hashira and declaring his desire is for all to be dead. Angered at his failure, Muzan takes control of Akaza's cells and causes him to bleed heavily.
It is one of the most loved Akaza's ships and his only famous het ship. Fans like portraying both Hakuyi and his demon form Akaza being deeply in love with Koyuki in fanarts, doujinshis and fanfics.
Because of his desire to become stronger and Doma's strength allowing him to surpass himself to become Upper Two, Akaza harboured an intense hatred of Doma. Doma, as apathetic as he is, considered him his "best friend", seemingly ignoring the contempt Akaza possessed.
His heart stopped multiple times in his mother's womb, and when he first entered the world, he was deemed stillborn, having no pulse and not breathing. When he was taken to be cremated, he escaped death by releasing his first cries. Muzan as a human.
People hated Akaza in the beginning since he was responsible for the death of Rengoku. However, as the story progressed, fans realized the extent of the suffering he had been through as a human. Owing to his poor financial situation, he resorted to stealing to supply medicines to his father.
Curse of Kibutsuji
This curse besotted any who partake of Muzan's blood must be careful. 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.
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.
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.
