Moving on to an even sadder part in the coming section is what gives us a closer glimpse into the life of Yoriichi.
How did Yoriichi Die?
Despite having a demon slayer birthmark, which shortens life to 25 years of age, he went on to live up to 80 years of age. But he eventually went blind. Yoriichi was killed in a fight with his younger brother due to some conflict. This was not a Nobel end of legend who was untouched by many demons and defeated by his brother. A sad end indeed. But the part remains unanswered about why Muzan was so scared of the Yoriichi. Let`s find out.
Why Was Muzan Scared of Yoriichi?
Muzan was the archenemy and a villain of the Demon Slayer Corps. Once Yoriichi became Demon Slayer, he faced off with the Muzan. But the best part was when the heightened capabilities of the Yoriichi enabled him to gain details about Muzan, such as he has seven hearts and five brains. Such information helped the Yoriichi to inflict some deep wounds on the Muzan.

After this incident, Muzan, who was once undefeated, is now scared of a potent foe in the form of Yoriichi. In despair, Muzan splits his body into 1800 pieces, and even then, Yoriichi manages to kill 1500 pieces while barely escaping alive. This fight alone made the Yoriichi a great warrior with a swift-spreading reputation among friends and foes.
Connection of Yoriichi to his Brother, Michikatsu?
Michikatsu was the elder brother of Yoriichi and was jealous of him. He never liked his younger brother due to his closeness with his mother and the demon slayer mark on his forehead. But still, he had some soft corners in his heart and gave Yoriichi a whistle to blow whenever find himself in a dire condition. Ironically, his elder brother also pitied him due to the same reason as he hated him for the demon slayer mark on his forehead, and due to this reason, he was discriminated against and considered inferior.

Michikatsu`s jealousy got to another level once he realized the exceptional skill of Yoriichi. He was also afraid that his father could make him the family`s successor after coming to know his talent. But this proved to be untrue because Yoriichi ran away after the death of his mother. You will be amazed to know that later Michikatsu became a demon himself, and this made Yoriichi uncomfortable. And he finally succumbed to death after fatal injuries in a fight with his brother.
Is Yoriichi an Ancestor or Relative of Yoriichi?
Many fans consider that Tanjiro is the son of Yoriichi, but it is not the reality. In fact, Yoriichi is the teacher of Tanjiro`s ancestor, the Hinokami Kagura. This is also why Tanjiro could use the Sun Breathing Style to develop an exclusive connection between the two, one of the most important in the series.

It is interesting to share that Tanjiro and Yoriichi never shared any family ties but just a common friend named “Kamado Sumiyoshi”. He was the ancestor of Tanjiro. The descendants of the Tanjiro inherited Sun Breathing Styles from its originator. Additionally, the earrings of the Tanjiro are believed to have been handed over in his lineage from Yoriichi as a gift probably.

Why Yoriichi Resembles Tanjiro?

The only living blood relation Yoriichi had was with the Muichiro Tokito. You need to know that Mist Hashira is the descendant of the Michikatsu, the twin brother of the Yoriichi.

Legend has it that the Kamado family was saved from the demons by the Yoriichi while remaining a close friend afterward. Later he returned to the family after giving a detrimental blow to the Muzan and witnessing his brother becoming a demon. Yoriichi gave earrings to the family as a gift, who promised to succeed the gift to their descendants as a warm gesture of gratitude.
Sun Breathing and Hinokami Kagura
