Kyojuro was a young adult of tall stature and lean-muscular build. He had long bright yellow hair with red streaks akin to flames along 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. He was known to be charismatic and had an air of great optimism, having an enthusiastic smile plastered on his face nearly all the time.

(The triplets look just like Kyojuro because they have bright yellow hair but as they grow older they will start to grow red flaming streaks and they will have his thick black forcked eyebrows and his golden and red eyes)

Kyojuro wore a paler brown version of the regular Demon Slayer uniform, which consisted of a brown gakuran jacket, a white belt around his waist and tattsuke-hakama pants. Over this, he wore a haori with a white-yellow gradient pattern and red flame-like ridges at the end that his father Shinjuro had once worn and more than likely his father had worn when they were the Flame Hashira respectively. Finally, he wore red kyahan with yellow flames erupting from the bottom-up, with pale brown tabi socks and a pair of white zōri with red straps.

Kyojuro was greatly enthusiastic in regard to his duties as a Hashira, and often came across as cheerfully eccentric. He was amiable, pure of heart, and boasted extraordinary technique and swordsmanship stemming from strict practice and discipline. He was 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.

Kyojuro also loved his family immensely, displaying great respect and worry towards his father, Shinjuro Rengoku, despite him growing slowly more aggressive and apathetic towards Kyojuro. He was incredibly encouraging and optimistic towards his little brother, Senjuro Rengoku, believing in him and wishing him the best no matter what.

Ninth Form: Rengoku (玖くノ型かた　煉れん獄ごく Ku no kata: Rengoku?, lit. Ninth Form: Purgatory) - The most powerful Flame Breathing technique. The user takes a high stance with their sword before dashing forward at high speeds. The technique is powerful enough to completely carve out the ground in its wake.

Standard Nichirin Katana: Kyojuro carried a standard sized and shaped Nichirin katana with a red flame-like pattern along with the words Destroyer of Demons (惡あっ鬼き滅めっ殺さつ Akki Messatsu) engraved on the side of the blade. The handle of the katana is wrapped in cords of white silk. The tsuba of Kyojuro's katana is shaped like a flame with a red core and orange border. He also carried a standard sword sheath that was white and grey in color.

The Rengoku family has long since had a practice called "Kankagari" (觀かん篝かがり kankagari?). For the duration of their pregnancies/gestation period, every seven days the wives of the Rengoku family will spend two hours gazing at a large flaming torch. This seems to be what causes the men in the family to have flame colored hair.
