Yoriichi TSUGIKUNI

Yoriichi Tsugikuni was the strongest demon slayer to ever live, and the only one capable of defeating Muzan Kibutsuji, the progenitor of all demons. He was born with a natural ability to see the "Breath of Sun," a technique that allows the user to harness the sun's power to slay demons. Yoriichi was also a master swordsman, and he developed several new forms of the Breath of Sun that were later passed down to the Demon Slayer Corps. Yoriichi was a kind and compassionate man, and he always fought to protect the innocent. He was also a very skilled teacher, and he helped to train many of the Demon Slayer Corps' most powerful swordsmen. Yoriichi eventually died of old age, but his legacy lived on. His techniques and teachings continued to be used by the Demon Slayer Corps, and they played a vital role in the eventual defeat of Muzan Kibutsuji. Yoriichi was a true hero, and he will always be remembered as one of the greatest demon slayers of all time.
