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.
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.
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.
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 one of the most ruthless and insanely strong demons under Muzan Kibutsuji. As Upper Moon 2, he proves to be the absolute antithesis of Akaza. Moreover, their contrasting personalities as demons or mannerisms of rising up in the ranks are the major reasons for Akaza's hatred towards Doma.
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.
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.
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.
One thing that Demon Slayer fans have noticed is that Akaza refuses to eat or kill women.
As it turns out, Akaza was never truly an evil antagonist. Akaza is a well-written adversary, and his tragic backstory adds depth to his character. Even after forgetting his memories as a human, his feelings of empathy and remorse were still present.
Akaza is an upper-rank-three Demon and one of the most faithful minions of the Demon king Muzan Kibutsuji.
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.
Since Akaza became a demon, he's been a loyal subordinate to Muzan for centuries. However, Akaza held no respect, awe, or hatred towards him, seeing Muzan as an order giver. while seeing himself as a loyal follower. Despite his loyalty to Muzan, Akaza had a personal code of honor.
There is hostility between Kokushibo and Akaza. He doesn't get along with Akaza, since he sees him as a disgruntled individual who disrespects the Kizuki who are of a higher ranking than him.
Muzan likely believed it possible that one day, Doma could become strong enough to survive sunlight, so killing him might've been detrimental to the reason Muzan made him a demon in the first place.
However, in truth, as revealed after her death, Muzan sees Daki as a tool to keep her brother, Gyutaro, in line, deeming her to be the main reason why the "true" Upper Rank 6 was killed and in truth does not think highly of her and deeming her as someone not very intelligent.
It is revealed that Muzan's true fear of dying and immense desire to live and survive was due to him being born "dead," where his heart would constantly stop in his mother's womb and was assumed stillborn until he fought to breathe before his cremation.
His distain for the weak stems from when his teacher and fiancé were poisoned by a rival dojo who was unable to defeat Akaza in a fair fight when he was Hakuji and his obsessive pursuit of strength comes from his buried desire to help his loved ones but has been twisted by his demonic transformation.
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.
However, after his death, he accepted that he is wrong and that Heaven and Hell actually do exist. Doma also displayed what arguably is his first true emotion, love, when he proclaimed his love for Shinobu after finding her cute.
Inosuke's Father Was Abusive
Doma tells Inosuke that his mother was singing a lot, particularly a lullaby called “pinky promise.” It seemed as if mother and child were safe and happy at last; however, when Kotoha soon found out that Doma was a Demon and eating some of the worshippers, their happiness crashed.
However, Doma was born to be a sociopath who showed or felt no emotions, and he only saw his followers as foolish and pitiful worms begging him for mercy. When Doma was a boy, his mother killed his father after finding out he had been cheating on her, before she took her own life.
