Kyojuro Rengoku| Demon Pets au

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. This was further accentuated during his death where his final words for his father and his little brother were "take care of your body" and "follow your dreams no matter what". Kyojuro also believed that if someone lacks immense skill, their hard work towards their dreams and desire to help people doesn't count for nothing.

Beneath his enthusiastic demeanor, Kyojuro was very logical and tactically intelligent, acting quickly and precisely in battle, especially when the lives of others are on the line. Kyojuro was also great in seeing talent in others, even in Nezuko Kamado, a demon which he wanted to kill beforehand, after seeing her risk her lives to fight and protect others. Though he was extremely optimistic, Kyojuro did sometimes have a sense of foreboding that those he believed in might die, especially his friends who he cared deeply for. He, like most Demon Slayers, absolutely detested demons, usually because of their heinous deeds or because of their clashing moral values. Despite this, Kyojuro recognized and accepted Nezuko as a member of the Demon Slayer Corps after seeing her risk her life to protect innocents, showing that Kyojuro was capable of not letting his hatred for demons cloud his judgement.
