Rengoku Kyojuro’s final moments at the hands of Upper Kizuki demon

Flame Hashira, Rengoku Kyojuro’s final moments at the hands of Upper Kizuki demon, Akaza. With the words “Set Your Heart Ablaze”, the episode begins with a tribute to Rengoku and the trigger that will likely spur Tanjiro into action and grow stronger. Rengoku had been established in the previous arc as a mentor who quickly developed a bond with Tanjiro and even accepted him as his apprentice, technically making Tanjiro his Tsuguko.
