Keep your heart burning!
Kyojuro is a young adult of tall stature and athletic build. He has long bright yellow hair with red streaks with two shoulder-length bangs and two chin-length bangs on the side of his head, black forked eyebrows, and golden eyes that fade to red with white pupils.
Kyojuro wears a paler brown version of the regular Demon Slayer uniform, which consists of a brown gakuran jacket, a white belt around his waist and hakama pants. Over this, he wears a haori with a white-yellow gradient pattern and red flame-like ridges at the end that his father Shinjuro once worn and more than likely his father worn when they were the Flame Hashira. Finally, he wears red tabi socks with yellow flames erupting from the bottom-up, with a pair of white zōri with red straps.
Kyojuro is greatly enthusiastic in regard to his duties as a Hashira, and often came across as cheerfully eccentric. He is amiable, kind and boasted extraordinary technique and swordsmanship stemming from strict practice and discipline. He is an honorable warrior who adhered to his code of morals and principles that was instilled into him by his mother at a young age—the most significant being his belief that those who were born strong have a duty to protect the weak.
Abilities and Powers
As a Hashira of the Demon Slayer Corps, Kyojuro is a very powerful swordsman. Even Demons as strong as Akaza, Upper Rank 3 and the fourth-strongest of the known Demons, acknowledged Kyojuro's strength. He even went as far as to offer to turn Kyojuro into a Demon so he could surpass his human limits and become stronger, something he only offered to swordsmen whose abilities he believed were refined to their utmost. Akaza also complimented his battle spirit and stated that it is getting close to the "domain of supremacy," which meant that he is close to obtaining the transparent world, something only the strongest few Demon Slayers have access to. His father, Shinjuro Rengoku, stated that, after his son abandoned what he taught him, Kyojuro trained himself into the level of a Hashira after reading through an instruction book of the Flame Breathing style, a book which only had 3 volumes.
