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.
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.
In Demon Slayer, despite being the strongest demons, the Upper Moons were looked down on by Muzan. The original demon often expressed his disappointment towards them.
Akaza is an upper-rank-three Demon and one of the most faithful minions of the Demon king Muzan Kibutsuji.
Hantengu like all members of the Twelve Kizuki is shown to be faithfully loyal to Muzan and following each and everyone of his orders and demands without question despite Muzan's usual demeaning and condescending attitude towards 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.
Akaza from Demon Slayer is perhaps the best-written villain in the series. Akaza's personality has numerous complexities and contradictions that define him. He is exceptionally polarizing in the fandom. Anime-only fans hate Akaza because he killed Rengoku during the Mugen Train arc.
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.
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.
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.
Akaza. 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.
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.
Originally a human, Muzan suffered from a terminal illness, during an experimental treatment, Muzan became the first ever demon. He is also the progenitor of most other demons and the leader of the Twelve Kizuki. He is also the archenemy of the Kamado family, particularly both Tanjiro Kamado and Nezuko Kamado.
Gyomei's Nichirin weapon is quite peculiar, as instead of a sword, he has a Flailed Spiked Mace connected with an Axe. However, he could kill a Demon by landing rapid blows until daybreak. Gyomei can defeat Akaza without even awakening his Demon Slayer mark.
It could be because of Koyuki that he refused to kill or eat women. For Muzan to give Akaza special permission, he must have known the exact details of the events that transpired. While the manga did not explicitly mention the reason, it could be because of Koyuki's effect on Akaza back when he was human.
Akaza also hated weakness, which was something he saw in Tanjiro from the moment that they met. His fight against Tanjiro unlocked the rest of his suppressed memories and allowed him to finally accept his death. Akaza hated Tanjiro as a demon, but he only let go of that hatred when he finally remembered his humanity.
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.
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.
1 Yoriichi Tsugikuni (Demon Slayer)
Yoriichi's mastery of the Sun Breathing technique, combined with his incredible speed and agility, made him a formidable opponent for Muzan.
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.
