Why does Kyojuro Rengoku shout all the time in Demon Slayer? The Flame Hashira,Kyojuro was one of the most powerful Demon Slayers in the series, tasked with ridding the land of creatures much stronger than normal humans. His big moment in the spotlight was during the Mugen Train Arc, where he worked with Tanjiro Kamado, his sister Nezuko, and fellow Demon Slayers Zenitsu Agatsuma and Inosuke Hashibira to stop a demon who had been hiding on a train.
Kyojuro’s bright – and somewhat abrasive – personality initially clashed somewhat with Tanjiro and his team, who were often not quite sure how to act around the higher-ranked Demon Slayer given his quirks. Most noticeable of these is Kyojuro’s way of speaking, as the Hashira had a noticeable habit of shouting almost everything he said, especially when food was involved. With Rengoku’s lack of volume control noted as weird by other characters in the series, many have wondered as to whether there is a reason for this trait, or if it is simply reflective of Kyojuri’s constant exuberance.
One popular theory is that Kyojuro talks so loud as a result of his first ever mission as a Demon Slayer. A manga story detailed Flame Hashira Kyojuro Rengoku’s backstory, showing his fight against the Flute Demon, who had the ability to conjure a flute that manipulated anyone who heard it – believing Kyojuro, too, would be no match for this ability. That might have ended up being the case if Kyojuro did not burst his own eardrums in order to temporarily deafen himself, allowing him to defeat his enemy. Muffling all sound meant he had no fear of being controlled by the Flute Demon, but doing so might have also damaged his hearing permanently, potentially explaining his constant shouting as a result of his inability to hear how loud he is.
This said, Kyojuro’s loud voice did complement the sure way he was able to command any room he entered, meaning it may well have simply been a character trait regardless of his fight with the Flute Demon. As the Flame Hashira – and a master of his own breathing technique – Rengoku lead by example for the newer Demon Slayers such as Tanjiro, which was a task Kyojuro took seriously. Even against terrible odds, he never stopped smiling and encouraging others. This unwavering confidence fit well with the boisterous way he spoke.
Demon Slayer owes its success partially to the creation of such unique character as Kyojuro Rengoku – to the extent it’s a sure thing that speculation about these figures will remain rife long after the anime has come to a close. With the beginning of season 2 on the horizon, viewer fascination with what motivates the cast of Demon Slayer is sure to only increase, no doubt leading to countless more fascinating fan theories.
