Nevertheless, before things proceed any further, Tanjuro Kamado is Tanjiro Kamado's father's name. He died before a major event in the
Tanjiro's connection to Yoriichi is not through blood relation, but through their similar appearances, which is due to the divine nature of Sun Breathing.
Tanjuro Kamado was the name of Tanjiro Kamado's father. He passed away before the event of the main story of the Demon Slayer.
I'd even go as far as to say that he could contend with Muzan, possibly beat him if he was health. Even by the end of the series, Tanjiro admits that he's nowhere near as proficient as his dad was with the Breath of the Sun but still managed to keep a weakened Muzan at bay.
He wasn't a Demon Slayer but Tanjuro was exceptionally strong. While on the brink of death with that horrible disease (which made his body incredibly weak and frail) he was still strong and fast enough to slay a bear more than two meters tall.
The warrior Muzan feared was a swordsman named Yoriichi Tsugikuni. Yoriichi was the only slayer before Tanjiro who came close to killing Muzan, and the flashback of their fight occurred in Chapter 187.
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. Hanafuda Earrings are a symbol of Sun Breathing users, traditionally passed down from generation to generation as a family heirloom.
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.
Gyomei Himejima
Gyomei Himejima, the Stone Hashira, is the strongest Hashira in the Demon Slayer corps in terms of strength and swordsmanship. He is the only person who uses spiked flails and an axe instead of standard swords to kill demons.
Tanjiro certainly did a lot of good with his Water Breathing techniques, but his ability to use Sun Breathing both gives him an edge in battle and allows him to stand out among the incredibly powerful Hashira he fights alongside.
That man, he wasn't Tanjiro's father. He was Yoriichi, the first and legendary Demon Slayer, who managed to defeat Muzan and almost kill him. That's him. Tanjiro's father wasn't a Demon Slayer, he had a special dance only the Kamado family knew.
So, not only could Tanjuro use his mastery of the Hinokami Kagura for his dance, but he was also an excellent warrior despite his poor health. Tanjuro Kamado bore a mark on his head similar to Tanjiro's own scar, identifying Tanjuro as a chosen wielder of Sun-Breathing.
It is also noted that Tanjiro's father, who taught him the various forms of Sun-Breathing, was born with a scar on his head.
Demon Slayer's season 3's latest episode has left fans on edge with Tanjiro's discovery of Yoriichi Tsugikuni's Type Zero sword.
Conclusion: Kokushibo, the upper moon rank 1 demon and Yoriichi are not Tanjiros' father and neither are Tanjiro's relatives. However, Kokushibo and Yoriichi are siblings and respect each other a lot despite Kokushibo hating the entirety of his brothers' being.
It was because after being shown his overwhelming power, Muzan avoided him as best as he could. He didn't have another chance to kill him.
8 Shinobu Kocho, The Insect Hashira
That being said, she's arguably the weakest Hashira when it comes to pure strength.
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.
When it comes to pure strength, Shinobu Kocho is the weakest Hashira in Demon Slayer. She doesn't even have enough strength to decapitate a demon's head and she makes up for it by injecting poison into the demons.
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.
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.
Just to be clear: the scene that Tanjiro sees is of his ancestor Sumiyoshi, who is aided by the legendary demon slayer (and Sun Breathing creator) Yoriichi.
