Is Yoriichi Tsugikuni Related to Tanjiro? The Truth Behind the Sun-Breathing Legend

If you are a fan of Demon Slayer: Kimetsu no Yaiba, you might have wondered about the connection between Yoriichi Tsugikuni and Tanjiro Kamado. They look very similar, they both use the Sun-Breathing style, and they both wear the same hanafuda earrings. Are they related by blood? Or is there another explanation for their resemblance? In this article, we will explore the truth behind the Sun-Breathing legend and his relationship with Tanjiro.

Who is Yoriichi Tsugikuni?

Yoriichi Tsugikuni was a legendary Demon Slayer who lived nearly 500 years ago during the Sengoku era, the Golden Age of Demon Slayers. He was the inventor of Breathing Styles, being the one who created the first ever Breathing Style that would eventually become the Hinokami Kagura used by Tanjiro Kamado and members of the Kamado Family.

Yoriichi was born with a mark of a Sun-Breather on his forehead, which gave him extraordinary abilities such as enhanced strength, speed, reflexes, and endurance. He could also see into the Transparent World, which allowed him to perceive the inner workings of living beings and predict their movements. He was a master swordsman even as a child, and he developed his own unique sword technique that could cut through anything.

Yoriichi had a tragic life, as he lost his wife and unborn child to demons, and his twin brother Michikatsu became a demon and joined the Twelve Kizuki as Upper Rank One. Yoriichi dedicated his life to hunting down demons, especially Muzan Kibutsuji, the progenitor of all demons. He encountered Muzan once and almost killed him with a single slash, but he hesitated to ask him a question and let him escape. Yoriichi considered himself a failure for not fulfilling his destiny of eradicating all demons.

Yoriichi died of old age, but his legacy lived on through his teachings and his earrings. He taught Breathing Styles to other Demon Slayers, but none of them could master Sun-Breathing. He also gave his earrings to his friend Sumiyoshi, who passed them down to his descendants.

How is Tanjiro Kamado related to Yoriichi Tsugikuni?

Tanjiro Kamado is not a direct descendant of Yoriichi Tsugikuni, but he is related to him by friendship. Tanjiro is a descendant of Sumiyoshi, who was a close friend of Yoriichi. Sumiyoshi was rescued by Yoriichi when he was attacked by a demon, and they often met and talked afterwards. Yoriichi entrusted Sumiyoshi with his earrings as a symbol of their bond.

Tanjiro inherited the earrings from his father Tanjuro, who also taught him the Hinokami Kagura dance. The Hinokami Kagura is actually a form of Sun-Breathing that was passed down by the Kamado family as a tradition. Tanjiro learned Sun-Breathing from his father’s dance and from reading Yoriichi’s memories in his dreams.

Tanjiro also inherited some physical traits from Yoriichi, such as his maroon eyes, spiky hair with red tips, and facial features. This is because Sumiyoshi’s wife was distantly related to Yoriichi’s mother Akeno Tsugikuni, who shared these characteristics with her son. Therefore, Tanjiro is genetically related to Yoriichi through his maternal line.


Yoriichi Tsugikuni and Tanjiro Kamado are not blood relatives, but they are connected by friendship and fate. They both share the same Sun-Breathing style, the same hanafuda earrings, and some physical resemblance. They both have a strong sense of justice and compassion, and they both face Muzan Kibutsuji as their ultimate enemy. They are two sides of the same coin, representing the light and hope of humanity against the darkness and despair of demons.

According to , Demon Slayer: Kimetsu no Yaiba is one of the most popular anime series in recent years. It tells the story of Tanjiro Kamado, a young boy who becomes a Demon Slayer after his family is slaughtered by demons and his sister Nezuko is turned into one.
