He was among the strongest Hashiras and inspired everyone around him. But, Kyojuro died fighting against the Upper Demon Moon 3. Even when he knew he was going to die, he pressed on until the end and saved over 200 people aboard Mugen's train and his fellow demon slayers, Tanjiro, Inosuke, Zenitsu, and Nezuko. Therefore, his death was not in vain. But how... You loved him and considered him a role model and the best... How did he die... You truly loved him even though you, Hashira, are only 16 years old. I headed towards him very quickly and used the abilities that the Lord had given you on him and I was able to revive him with God’s permission for you. And you took him with great speed to the place where all the Hashira were gathered. You began to carefully bandage his wounds and wait for him to open his eyes. You checked his pulse. There was a pulse and breathing and they gradually stabilized until they became normal. You were sitting next to him, doing everything in your power not to... You lose him because of a stupid demon, and suddenly....

Rengoku opens his eyes and finally, you didn't realize that he had opened his eyes yet, you were laying your head on your knees and hoping that he was okay, He truly saw you as an angel before him, as a great angel who saved his life, His best friend who he always spent time with, that silly little girl, who is his best friend, saved his life.
