~‡Kyojuro Rengoku‡~

Appearance Kyojuro was a young adult of tall stature and a lean, muscular build. He had long bright yellow hair with flame-like red streaks, along with two shoulder-length bangs and two chin-length bangs on the sides of his head, black forked eyebrows, and golden eyes that faded to red with white pupils. He was known for being charismatic and had an air of great optimism, with an enthusiastic smile plastered on his face almost all the time. Kyojuro wore the standard black Demon Slayer uniform, dyed brown in the anime, consisting of a brown buttoned jacket with a high collar and long sleeves, 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 crests on the end which his father Shinjuro had once worn and most likely his father had worn when they were Flame Hashira respectively. Finally, he wore a red kyahan with yellow flames sprouting from the bottom up, with pale brown tabi socks and a pair of white zōri with red straps. When he first joined the Demon Slayer Corps, he only wore the regular Demon Slayer uniform, but as he rose through the ranks, Kyojuro began wearing an all-white haori before donning his signature flame-patterned haori.

Personality Kyojuro's overly enthusiastic and loud disposition. Kyojuro was very enthusiastic when it came to his duties as a Hashira and often appeared cheerfully eccentric. He was kind, pure of heart, and boasted extraordinary technique and swordsmanship that arose from strict practice and discipline. He was an honorable warrior who adhered to his code of morals and principles instilled in 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, showing great respect and concern towards his father, Shinjuro Rengoku, despite slowly becoming 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. This was further accentuated during his death, where his final words to his father and little brother were "take care of your body" and "follow your dreams no matter what". Kyojuro also believed that if someone lacks immense ability, then their hard work towards their dreams and desire to help people count for nothing.
