Abilities. Demon Body: Unique from other demons, he possesses seven hearts, and five brains. These are responsible for his powerful vitality, should any of them be harmed, he will be severely weakened.
Possessing the grand total of seven hearts and five brains, these extra organs seemingly are largely responsible for the majority of his abnormally powerful constitution.
Instantly, Yoriichi's ability, the power to see the transparent world with his heightened perception, enables him to see through Muzan and discover that the powerful demon possesses five brains and seven hearts that can move at will within his body.
It's true. Muzan has had more than one family over the course of his millenia-long life. This includes the birth family he had before he became a demon.
Moving to kill him once and for all, Yoriichi instead heard the sound of teeth cracking as Muzan's body burst into hundreds of small pieces. Caught off-guard, he was only able to destroy 1,500 of the 1,800 pieces, leaving the rest to escape for Muzan to regenerate again.
5) Yoriichi
Case in point: he was the only one who could single-handedly take on Muzan and drive him to a corner. Yoriichi would be able to defeat every single Hashira on this list without breaking a sweat. Such was his reputation and skill in swordsmanship.
But if we are talking about the human form, then it's a big fat NO, because Tanjiro has just mastered the Sun Breathing whereas Yoriichi is the inventor of it, also he's way more powerful and holds an unfathomable battle intellect, larger than any Demon Slayer in history, so in conclusion, no one is remotely close to ...
Hoshiko Kibutsuji. The first female demon [of a different orgin], and the younger sister to Muzan Kibutsuji. She loves her brother and was the one who had attacked that man who wore the hanafuda earrings.
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.
Tanjiro. Muzan speaks his last thoughts and turns Tanjiro into the new demon king and subsequently his spiritual successor.
Yoriichi was incredibly proficient in his Sun Breathing, being able to take down demons effortlessly and even overwhelm the Demon King and strongest Upper Rank.
Initially, Tanjiro's accuracy and strength were not up to the mark, which is why Muzan was able to avoid his attacks. However, Tanjiro accurately performed the thirteenth form and inflicted a ton of damage on the Demon King.
This color was first discovered by Yoriichi Tsugikuni when he became a Demon Slayer due to his Sun Breathing. In fact, it is a category of Yoriichi's gifted powers and abilities, which is meant to hamper the regeneration of Demons.
Abilities. Demon Body: Unique from other demons, he possesses seven hearts, and five brains. These are responsible for his powerful vitality, should any of them be harmed, he will be severely weakened.
As the Demon King, Muzan can control all those who have assimilated his blood to become demons, with Nezuko Kamado, Tamayo, Yushiro, and later Chachamaru being the only exceptions.
After he neutralizes Tamayo's poison and emerges from his flesh cocoon, Muzan's hair grows in length and turns white due to Shinobu's poison accelerating his age.
As a human, Daki was known by the name 'Ume' instead. This was a rather peculiar choice for a name, especially since Ume was the disease that killed Daki's mother! While the death of Daki's mother was anything but tragic — given how abusive she was — his name does hint towards the manner of her demise.
Conversation. Fun fact: The reason why Enmu was able to say Muzan's name out loud without dying is because they're married!
The first demon that is said to have existed was Muzan Kibutsuji. The one who turned him into a demon was a generous doctor from the Heian Period, who wanted to save Muzan from death since, at the time, he was diagnosed with a disease which would kill him before he turned twenty.
Muzan Kibutsuji ( 鬼 き 舞 ぶ 辻 つじ 無 む 惨 ざん , Kibutsuji Muzan?) is the main antagonist of Demon Slayer: Kimetsu no Yaiba.
Tanjiro Kamado
Tanjiro is considered to be Muzan's main nemesis throughout the series.
Technically, the elder of the two Sakuras` was actually Muzan`s child, by way of his mistress (Lady Jade Wong), who had one of her eggs inserted into Anne`s body.
Mitsuri Kanroji is another Hashira who Tanjiro could definitely beat in Demon Slayer. Mitsuri's main trick up her sleeve is her muscle composition, which makes her muscles eight times denser than that of a normal human's. In other words, she's incredibly strong and powerful, and tough with plenty of endurance as well.
It was Yoriichi's sword, he found it inside Yoriichi Type Zero doll when he destroy the head. And then hotaru took the sword to fix it. Tanjiro also use Kyojuro's tsuba in this sword.
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.
