His father, Shinjuro Rengoku, was the previous Flame Hashira and trained him in swordsmanship from a young age. Ruka was very kind but seriously ill. Before she died, she gave Kyojuro a message that shaped his entire life: "Those born strong have a duty to protect the weak." This belief became the core of Rengoku’s personality. He promised to use his strength to help others and protect innocent people. After Ruka died, Shinjuro became bitter and depressed. He stopped being a Hashira, drank heavily, and refused to train his sons. Instead of giving up, Rengoku trained himself by studying the old Flame Breathing manuals left in his house. He had a younger brother, Senjuro Rengoku. Kyojuro always encouraged him and acted as a role model. When Kyojuro eventually became the Flame Hashira, he proudly told Senjuro that even if Senjuro chose a different path, he would still support him.
