Yoriichi Tsugikuni

Yoriichi Tsugikuni is the strongest Demon Slayer in history, known for his calm and kind nature, incredible swordsmanship, and for creating Sun Breathing, the original and most powerful Breathing Style. Born with the Demon Slayer Mark and the ability to see the "Transparent World," he could predict his enemies’ moves with ease. Despite his strength, his life was marked by loss and betrayal, especially by his twin brother, Michikatsu, who became the demon Kokushibo. Even Muzan, the strongest demon, feared him.
