Yoriichi Tsugikuni

The strongest Demon Slayer ever, Tsugikuni Yoriichi, has a big role to play in the anime/manga series—Demon Slayer (Kimetsu no Yaiba). He has such an influence on the story as we will see when you read this piece and if you have already read the manga, then you know. So let’s look at how Tsugikuni Yoriichi came to become the strongest demon slayer!

Going down the history of Yoriichi, he was the first ancestor of the Kamado family. He was the one who taught demon slayers how to perform the very breathing techniques that Tanjiro and others have been training to perfect.

He was born with the Demon Slayer Mask, without evening achieving the power, he was already gifted. Though, his father never got to care for him and detested him due to this mark. He was neglected by his father, but was very close to his mother. When Yoriichi was young, his father even tried killing him, thinking of him as something evil.

As he grew up, Yoriichi found that his aim in life was to become a samurai. With his first sword lesson, he even overpowered his teacher—showing how proficient he is with his sword skills. Yoriichi since then had been shocking everyone with his innate skills and abilities. Born with demon slayer, mark prophecies something bigger than we could ever imagine. 

He was the first breathing-style user and the strongest demon slayer ever born. Yoriichi and his twin brother Michikatsu were born during the Sengoku period. This was the time when twins were considered a bad omen.

When Yoriichi met Muzan, he understood the reason he was born. He was born to defeat Muzan. He was the only member of the Demon Slayer Corps to be able to corner Muzan Kibutsuji, overwhelmed him instantly, and nearly killed him before he was able to flee. Muzan was severely damaged by that encounter, referring to him as a monster and trembling in shock at the sight of his earrings, whereas other demons who have never met Yoriichi shudder at the mere thought of him.

The Abilities:

The abilities that set aside Yoriichi from the rest, his true powers are still a mystery, but unique abilities already resided in him –

  • Yoriichi fought his older twin brother Kokushibo, who changed into a demon, just before he passed away at the age of at least 85. He soon took the initiative in the conflict despite his senior age and apparent blindness, cutting Kokushibo’s throat before he ultimately passed away standing up, unharmed. While remarking that Yoriichi’s might was still at its peak, Kokushibo acknowledges that if Yoriichi had taken a second stroke before passing away, he would have killed him.
  • Yoriichi’s bright red Nichirin blade was immensely powerful against demons and slowed down regeneration. The strength derived from the sword upgraded his stamina to beyond its peak. He also had abnormal perception from his eyes, immeasurable strength and his physical capabilities are unknown—though remember he is still human. A human with such a power is closer to God than any demon ever could dream of.
  • He is the Demon Slayer Mark’s ancestor because he was born with it and benefited from its powerful physical effects his entire life. Yoriichi was able to resist death and lived to be nearly 85 years old, which set him apart from all other mark-users of his day. Yoriichi was the first person to ever possess the Mark and was likely born with it naturally, unlike all other mark bearers who must through training to acquire it, however, the reason for his immunity to Mark’s effects is currently unclear.
  • Yoriichi has had access to the Transparent World since birth, and he is surprisingly proficient with it. This is demonstrated by the fact that he can predict when to strike someone by watching for their muscles to contract and their lungs to expand. Yoriichi also had an advantage over Muzan because he could quickly identify those weaknesses and outnumber him.

Final Thoughts!

From the moment he was born to his death, Yoriichi Tsugikuni never ceased to impress. His calmness, righteousness, and his strength is unparalleled. To put it together, if Yoriichi supposed to fight against Muzan and The Upper Moons combined, he’d still win without much effort. Undoubtedly, he is the most powerful character in the demon slayer universe.
