Pivotal moments within anime may shape an entire storyline. Fans enjoy speculating about how everything would have changed with one simple change. In Demon Slayer, one such moment came in the tragic fight between Kyojuro Rengoku, Flame Hashira, and Akaza, Upper Rank Three. Rengoku's death certainly had a deep impact on the plot; what if he survived that fateful fight? His survival would have completely altered the events of the story, as so many key moments in the story would be rewritten, along with the trajectory the Demon Slayer Corps takes.
