When Muzan killed Tanjiro's family, he injected each of them with a massive dose of his blood, hoping that the sheer power they'd get from him would birth a demon capable of walking in the sun.
He passed away before the event of the main story of the Demon Slayer. It is not mentioned how long Tanjuro had passed before the story, but in several flashback scenes, we can see him interacting with a younger Tanjiro.
However, in the Demon Slayer manga Muzan reveals his motivation for attacking the Kamado family. It turns out that Muzan attacked the Kamado family and specifically turned Nezuko into a demon in an attempt to create a demon that would be able to withstand being in the sunlight.
First of all, Kibutsuji Muzan definitely killed the Kamado family and turned Nezuko into a demon. Urokodaki Sakonji himself confirms it in a flashback on Chapter 11 of the manga and Episode 6 of the anime, saying that only Muzan has the ability to turn other people into demons.
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. nxt.
Thus, Muzan created demons for hundreds of years even when he didn't want to turn someone. Since he didn't know anything about the Blue Spider Lily medicine, he needed others to find the plant for him by happenstance. This is the general reason why Muzan turned Nezuko 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.
Everyone can't bring themselves to kill Tanjiro. Zenitsu, Nezuko, Inosuke, and Kanao gave Tanjiro motivation and Tanjiro then mentally beat Muzan, and then Muzan is gone for good.
But the crowning moment of his achievements is when he epically slices off Daki's head and makes a run for it—after all, she won't die until her brother's head is also sliced. Unfortunately, Gyutaro spots Inosuke and stabs him right through where his heart should be with a sickle imbued with deadly poison.
Who killed Kibutsuji Muzan? The answer to that is, all the members of the Demon Slayer Corps.
Nezuko's Sunlight Immunity in Demon Slayer is Tied to the Blue Spider Lily. Nezuko having eaten the Blue Spider Lily at some point could explain her immunity to sunlight, and Demon Slayer: Kimetsu no Yaiba has already worked to justify that.
Enraged by his threats, Muzan would send multiple Demons to kill Tanjiro such as Yahaba, Susamaru and Enmu throughout the series. As mentioned, it is revealed that Muzan's desire to destroy Tanjiro stemmed from his hatred towards his previous nemesis, Yoriichi Tsugikuni.
He is the one demon that Tanjiro will never forgive or feel empathy for, likely because Muzan is evil by nature rather than by circumstances. Tanjiro feels sure that Muzan is evil because he's Muzan, not simply because he's a demon.
Is upper rank one Tanjiro's father? No, they are not related. Tanjiro, by PURE COINCIDENCE, heavily resembles Yoriichi Tsugikuni, the creator of Breath swordsmanship, the only other person to use Sun Breathing, and the only person Muzan ever feared.
Upper Rank 1: Kokushibo
However, what truly sets Kokushibo apart is his Blood Demon Art, Crescent Moon Blades. This unique technique allows him to wield crescent-shaped blades that can change length and speed instantaneously, making them a deadly and unpredictable weapon.
Tanjuro Kamado a recurring flashback hero from Demon Slayer : Kimetsu No Yaiba. He was the husband of Kie Kamado, and the father of Tanjiro, Nezuko, Takeo, Hanako, Shigeru, and Rokuta. Tanjuro was a flame dancer who used to dance the Hinokami Kagura during the winter.
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.
Towards the final arcs of the manga, Tanjiro is mortally wounded and dies during a fight with the Demon King Muzan. Though Muzan is also seriously injured, he uses the last of his powers to turn Tanjiro into a demon.
In her final moments, she apologized to Inosuke for failing to protect him and tosses him into the river as an attempt to save his life. She was ultimately killed and eaten by Doma, who claimed to have devoured her to the bone.
We first see Doma when he is still the Upper Moon Six while he is in the middle of eating a geisha. Later he becomes even stronger and rises to the position of Upper Moon Two. He dies because of the lethal amount of poison he absorbed through Shinobu Kocho's body followed by Kanao Tsuyuri beheading him.
Ultimately, Nezuko survives and finally turns into a human after being stuck as a demon for so long.
Don't go! DON'T LEAVE ME HERE! Muzan speaks his final words as he loses control over Tanjiro.
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.
Curse of Kibutsuji
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. Susamaru accidentally shot Muzan's name aloud, attempting to defend his honor with her mind clouded.
