Despite the curse of the Demon Slayer mark, Yoriichi Tsugikuni defied the odds and lived beyond the typical lifespan.
What if Tanjiro ACTIVATED the mark in episode 1?
With the end of Demon Slayer Season 4, Ufotable delivered the most cinematic experience the fandom could have asked for, ending with Hashira and Tanjiro's group entering the Infinity Castle. When our beloved protagonist, Tanjiro Kamado, finally confronts Muzan Kibutsuji and vows to behead the Demon King, viewers are glued to their screens waiting for Season 5.
Since its inception, Tanjiro has won the hearts of many anime fans worldwide, and his journey to save Nezuko and avenge his family's tragic death has been a rollercoaster of emotions for viewers. Despite Tanjiro threatening Muzan's life, the Demon King just smiles and dares the protagonist to act. However, there was one demon slayer who made Muzan Kibutji tremble with fear with his mere presence, and that was none other than Yoriichi Tsugikuni.
Yoriichi Tsugikuni is the creator of the Sun Breathing Style and the legendary Demon Slayer, who lived over 500 years ago. Surprisingly, Muzan encountered Yoriichi during one of his ventures, resulting in the Demon King's first experience of fear and fleeing the battlefield. Unfortunately, Yoriichi Tsugikuni always blamed himself for not decapitating Muzan and ending the carnage.
