She was married to Toshiya Fujita.
Koyuki was a frail, fair-skinned young lady with large, rounded pink eyes with white pupils shaped as flowers. She had black hair which was always tied into a large bun fastened with a hairpin and decorated with a Kushi (hair comb) and three snowflake hairpins.
HakuKoyu is a ship that isn't as noticed by the fandom, unlike the other canon ships such as TanKana, ZenNezu or ObaMitsu. However, most fans love them and enjoyed their love story, which showed their deep care for each other. It is one of the most loved Akaza's ships and his only famous het ship.
Later on during the battle within the Infinity Castle, Doma begins to tear up after hearing word of Akaza's passing, mourning his "best friend." However, Kanao is able to expose him saying that he does not feel any emotion and is simply acting, proving that Doma did not actually care for Akaza.
Before turning into a demon and changing his name to Akaza, he was named Hakuji Soyama. As a human, he was a martial arts prodigy who had a daughter named Koyuki.
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.
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.
Fandom. Why does Akaza respect women? Yep, because of his past. And he drinks plenty of respect women juice.
After Akaza's death, Doma says that he felt as if the Upper Rank had turned into a different creature before he died, and that his demise is inevitable because he never ate any women. Doma begins to cry over his 'best friend's' death, but Kanao just tells him to stop with the lies.
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.
Shizuka is seen often teasing Sanemi and making him annoyed, nevertheless, the two had still created a strong bond and relationship with each other. Eventually, after knowing each other for a while, Shizuka finally ended up having the courage and confessed, leading to them getting married after awhile.
Over a century ago, Akaza was a human by the name of Hakuji before being turned into a Demon personally by Muzan. He first appeared as the secondary antagonist of Mugen Train Arc, and grew to despise Tanjiro for humiliating him after Muzan reprimanded him for being unable to take his life.
Anne was originally planned to be Muzan`s older sister, who died by the hand of a Demon Slayer but that idea was scrapped, as the author knew practically nothing about Muzan`s early life. Instead, Anne became his wife, by which he had two children.
Don't go! DON'T LEAVE ME HERE! Muzan speaks his final words as he loses control over Tanjiro.
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.
The only Demon he despises the most is the Upper Rank Two: Doma. It is quite a shocker that the second most potent Demon in the Demon Slayer is not Muzan's favorite.
The first syllable in Akaza's name contains the the kanji that stands for gentle and docile. An individual who's believed to be gentle and docile shouldn't really have a scowl on their faces. This could be a major reason why Akaza was portrayed as a character that always keeps smiling in Demon Slayer.
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.
Muichiro can defeat Akaza easily with his petite body that leverages his speed. Moreover, his ability of Transparent World can aid him in landing a fatal blow on Akaza's weak spot.
