Name: Yoriichi Tsugikuni

Gender: Male

Status: Deceased (died of old age)

Age at death: 85

First Appearance: Manga, Chapter 170 (flashback)

⚔️ Legendary Swordsman
Yoriichi is the creator of the Sun Breathing technique (Hinokami Kagura), the first and most powerful Breathing Style.

All other Breathing Styles (Water, Flame, Thunder, etc.) are mere derivatives of Sun Breathing.

He was the only person who nearly killed Muzan Kibutsuji, the main villain, single-handedly.

His swordsmanship was so perfect that no one could truly replicate it.

👁 Demon Slayer Mark & Transparent World
Yoriichi was born with a Demon Slayer Mark, which granted immense power (most get it later in life).

He could see into the Transparent World, which let him view the inner workings of the body, predict movements, and strike with perfect precision.

He was one of the very few who lived to old age despite having the Mark, which usually shortens lifespan.

👥 Family
Yoriichi had a twin brother: Michikatsu Tsugikuni, who later became the demon Kokushibo (Upper Moon One).

Though he loved his brother, their paths diverged—Michikatsu became a demon out of jealousy toward Yoriichi's perfection.

🧘‍♂️ Personality
Yoriichi was extremely humble, calm, and kind-hearted.

He viewed his powers as a burden, not something to be proud of.

He never hated his brother, even after Michikatsu turned into a demon—he only regretted not being able to save him.

💥 Legacy
His Sun Breathing style was passed down through the Kamado family, disguised as a ritual dance—which is how Tanjiro Kamado inherited it.

Yoriichi became a legend among Demon Slayers, inspiring generations.

📌 Fun Facts
His sword was black, but when activated, it turned crimson red, dealing greater damage to demons.

He couldn’t finish off Muzan because Muzan exploded into pieces and fled—but the wounds Yoriichi inflicted never fully healed.





















-----My dream was to live a quiet life with my family in a small house where we would sleep side by side. I would be close enough to see the beloved faces of my wife and child and close enough to reach out and take their hands. That would have been enough. But even that did not come true. Demons exist in this beautiful world.
