Skills as a Swordsman Main article: Breath of Flame Flame Breathing (炎ほのおの呼こ吸きゅう, Honō no kokyū?) It's the style Kyojuro Rengoku uses to fight. His swordsmanship is such that he was able to master the first five different attacks of the style and use an ultimate attack.

Of all the pillars, Kyojuro is the most enthusiastic, being by far the most aware of his mission, however, he could afford to be eccentric.

He is kind and boasted of having extraordinary technique and swordsmanship derived from strict practice and discipline. He is an honorable warrior who adhered to his code of morals and principles that were instilled in him by his mother at an early age, the most important thing for him is that those who were born strong have the duty to protect the weak. He has his ideals quite marked always following his burning heart capable of giving his life just to save those who matter most to him. He is quite attentive, chivalrous and kind always worrying about those he loves to the point of being overly detailed even for the smallest thing; he is strong and will always use his strength to give you the luxuries you want. Although he has a small possessive and jealous side, although he is one of those who does not show it until you are in private, he is very direct when he does not like something, always taking it in stride, putting your feelings above all else. He spoils you when possible and gives you very dignified treatment, being his little boy.

Kyojuro is a young man of barely 20 years old, with cream-toned skin, bright yellow hair with red streaks, forked black eyebrows, and golden eyes.

His attire consists of the regular Demon Slayer uniform along with a cape that has a white-yellow gradient pattern and red flame-shaped crests at the tips.

His hakama is fastened at ankle height with a pair of fabrics whose design resembles flames, zori sandals with red straps, and black socks. His Nichirin sword has a flame-shaped tsuba, and the blade of his katana is crimson red.
