Nezuko, on the other hand, never was under Muzan's curse, it would seem. Instead, she used her will to protect her brother and other humans to fight off the curse. This is probably why Nezuko sleeps instead of eating humans. This also means her strength as a demon is based on her will to protect rather than feed.
Not being directly linked to Muzan like other demons, she can act independently of his will and not be destroyed for helping the Demon Slayers fight other demons. Nezuko is also different because she has never consumed a human since becoming a demon.
Fans later questioned the reason for letting Nezuko live. Fans believed this could have been a strategic move from Muzan. The theory states that Muzan wanted to create a demon that developed an immunity to the sun. Upon doing so, he would consume the aforementioned demon and become invincible.
Her final human transformation occurs in Chapter 196 of the manga. Ultimately, Nezuko survives and finally turns into a human after being stuck as a demon for so long.
Secondly, Muzan would probably… eat Nezuko and Tanjiro in the hopes of obtaining their sun-resistance abilities, and also since he wouldn't be able to convince them to become demons to work under him. This would allow him to become the ultimate demon.
As shown in her recollection, Muzan was shown to have attacked the Kamado family purely out of a whim, with him later injecting Nezuko with a gigantic amount of his blood only to see if she could survive or not, when she had seemingly died, Muzan was shown to have been initially disappointed and wondered if he could ...
During the Demon Slayer season 3 finale's depiction of Tamayo analyzing Nezuko's blood, it's shown that Nezuko's blood has blue elements to it, and since the Blue Spider Lily has the power to cure Muzan of his weakness to sunlight, the anime could be revealing that Nezuko's immunity comes from the Blue Spider Lily at ...
Why did Muzan cry at the end? The manga explains that Muzan found Tamayo four centuries ago when she was begging him to cure her of her illness. He turned her into a demon without telling her, and she went crazy. She mercilessly massacred her own family and after she was done, she cried for her loss.
Yet, for some reason, Tanjiro Kamado, the series' protagonist, never becomes a Hashira. Demon Slayer's protagonist Tanjiro Kamado starts out as an ordinary boy but has his entire life turned around after his family massacre. To make matters worse, his only surviving family, Nezuko, is turned into a demon.
Giyu would still instruct Tanjiro to train to become a Demon Slayer with Urokodaki. As there is no Nezuko, Tanjiro would have no reason to pity demons, and he'll be much more harsh that he would be if Nezuko was alive. Tanjiro would still manage to kill the Hand Demon and come back alive to Urokodaki.
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.
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.
Muzan, the King of Demons, is the strongest and also the primal demon in the world of Demon Slayer. Consuming his blood is enough to turn you into a powerful demon. He can control all the demons in existence, with only people with strong willpower like Nezuko being an exception.
While Muzan is extremely powerful, he isn't able to control two specific demons like he does most others. One of the demons he can't manipulate is Nezuko (Akari Kitō and Abby Trott), the half-human sister of Tanjiro.
Since Nezuko is from a Sun Breathing lineage, she can survive in daylight. After the final battle against Hantengu concludes, she can step into daylight, and many theories are available about the phenomenon. One of the theories is that her abstinence from consuming human blood is what saved her.
Before the final blow was struck, killing the Demon King, Muzan took down with him some heavyweights namely Obanai Iguro, Mitsuri Kanroji, and Gyomei Himejima— the last of whom is crowned as the most powerful Hashira. By the end of the manga, only Sanemi and Giyu were the only Hashira remaining.
Yoriichi Tsugikuni, the first swordsmen to ever use Breathing Styles, once nearly killed Muzan with Sun-Breathing, and Muzan has been both physically and psychologically scarred ever since.
However, after the final fight with Muzan the Demon Slayer corps got disbanded. After Muzan was defeated, all the demons he created also perished immediately, so there was no point of a Demon Slayer corps anymore. As a result, Zenitsu did not get to become a Hashira even after becoming strong enough to bie one.
During his final struggle, and as a way to slow down the effects of the sunlight, Muzan adopts an enlarged demonic infant form, approximately as tall as a 3 story building when standing up. In this form he has very pronounced blood vessels across his body, small claws in his hands and fanged teeth in his mouth.
Anne was a kind and loving soul and was described as the only person that Muzan had truly loved, besides his three daughters.
Muzan was born in Japan's Heian era, to a constant struggle to survive on account of his frailty. 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.
As Muzan is responsible for the death of her family, Nezuko hates him very much, and this hatred serves as fuel during her battles. Because of her unique abilities, she becomes sought after by Muzan, who hopes that by eating her, he will gain her immunity to the sun.
Weaknesses. Sunlight: Muzan is noted to be immune to being killed via decapitation, as seen when Gyōmei destroyed his head and he still managed to regrow it. Thus the only other known way that he can be destroyed is by sunlight.
Muzan's Recipe For Immortality
He wanted to be able to walk in the sunlight and live forever. In order to gain this, he needed two things: the Blue Spider Lily and the body of a demon who could withstand the sun.
