Demon Slayer Mark: Yoriichi is the progenitor of the Demon Slayer Mark, being born with it, possessing the tremendous physical abilities granted by its effects all throughout his lifespan. Unlike all other Marks users in his era, Yoriichi was able to defy fate and lived to about 85 years of age.
History. Yoriichi and his twin brother, Michikatsu, were born into the Tsugikuni clan within the middle of the Sengoku period, a time when twins were considered to be an extremely bad omen.
Fans think that Tanjiro was related to the legendary swordsman since he had the same earrings, and their appearances are similar as well. However, Tanjiro is not a descendant of Yoriichi Tsukiguni. Tanjiro is the descendant of someone who knew Yoriichi personally and was a good friend of his as well.
Many Kimetsu no Yaiba fans deduce that Yoriichi is Tanjiro's father, but that isn't the case. However, Yoriichi is responsible for teaching Tanjiro's ancestors the Hinokami Kagura, which has been passed down for generations.
Tanjiro is 17 during Final Arc (16 through most of the story). Meaning he was born around 1897. So Yoriichi died approximately 360 to 330 years before Tanjiro was born, give or take.
Only two Slayers were ever known to be older than 25 with a Mark. Yoriichi lived till old age, likely due to him having been born with the mark and thereby avoiding the curse altogether. Gyomei on the other hand did not activate his Mark until he was already older than 25.
Yoriichi would be able to defeat every single Hashira on this list without breaking a sweat. Such was his reputation and skill in swordsmanship.
Tanjiro's ancestor was a good friend of Yoriichi and arguably was one of his only true friends. Therefore Yoriichi gave the earrings as a gift, and since then they have been passed down the generations until they reached Tanjiro.
The episode begins with Tanjiro encountering the ghost of Yoriichi Tsugikuni, the creator of the Sun Breathing technique. Through a series of flashbacks, we learn about Yoriichi's tragic past and how he met the Kamado family.
Demon Slayer's season 3's latest episode has left fans on edge with Tanjiro's discovery of Yoriichi Tsugikuni's Type Zero sword.
Some of the characters who have faced Yoriichi and survived
This happened due to a treatment that had gone wrong. While he was being treated, Muzan killed the doctor because he was not able to observe any results.
No, they are not related.
Shortly before his death of at least 85 years in age, he battled his older twin brother, Kokushibo who turned into a demon. Despite his advanced age, he quickly gained the upper-hand in the battle with a single move, slitting his throat before he finally died standing up, unscathed.
Yoriichi was powerful enough to defeat Muzan; however, he couldn't do so. That's because he couldn't come down to kill his twin brother, leading to his own demise. Even to this day, Muzan is scared of Yoriichi.
Yoriichi was also very kind, once helping an elderly man reach his dying son, and showing love for his brother even after he became an Upper Rank demon.
Post-Transformation
Sensing their despair, Doma offered a chance to him and turned both Gyutaro and Daki into demons.
After Yoriichi saved the Kamados from demons back in the Sengoku Era, he taught the Hinokami Kagura to Tanjiro's ancestor. Almost every generation of the family attempted to perfect this Breathing Style, but Tanjiro is the only one truly "chosen" to wield the technique.
Tanjiro's earrings are modified hanafuda cards that have been passed down in his family. In Demon Slayer season 1, episode 19, “Hinokami,” Tanjiro's father Tanjuro wears the earrings. They were also worn by Yoriichi Tsugikuni, the originator of the Breathing Styles.
Yes, all lower moons and upper moons are weaker than Muzan.
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.
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.
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.
Since the mechanical doll was based off Yoriichi Tsugikuni, it had to be given six arms to recreate his swordsmanship style, the doll was also able to execute 108 various moves and is said to be stronger than an average human.
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.
