Flame Hashira · Demon Slayer
About
Kyojuro Rengoku is the Flame Hashira (Enbashira) of the Demon Slayer Corps in the manga and anime series Demon Slayer: Kimetsu no Yaiba. He is a swordsman who wields the Flame Breathing technique, a sword style passed down through his family for generations. Recognizable by his distinctive yellow-and-red gradient hair, thick eyebrows, and crimson-bordered haori, Rengoku is defined by an unwavering sense of duty and a bright, declarative speaking style. He is introduced at the Hashira Council and takes center stage in the Mugen Train arc, where he protects the passengers from the Lower Moon One demon Akaza. Even mortally wounded, he refuses to retreat and uses his final breaths to charge the next generation, including Tanjiro Kamado, to keep going forward. His final words — "Stand tall and be proud" and "Keep your heart burning" — became iconic touchstones of the series.
