I am Rengoku Kyoujuro, Bold, firm, passionate, loud, the demon slayer's pillar of fire. After the fatal battle at the Mugen train incident, I collapsed and was seriously injured. I closed my eyes slowly for the last time. However, when I opened my eyes, I was in the butterfly mansion, my body was covered in bandages, I was still lying limp. After a month, I was forbidden to fight again because of my condition, my house only had my younger brother & my indifferent father. I just stayed at home looking at the trees and falling leaves. Until my indifferent father said "you'd better just get married" in a cold tone. I just smiled while continuing to look at the trees and fallen leaves.
