Demon Slayer: Brother of the Butterfly Family, the Two Sisters I Protect

I am Butterfly Canglan, the biological brother of Kanae and Butterfly Shinobu. There is no time travel, no rebirth, no memory of past lives. When the moonlit night falls, the evil spirits tear apart the peace of Butterfly's family, and his parents die tragically in front of their eyes. In order to protect my two young sisters, I held the Nichirin Sword tightly and stepped into the endless night. On the one hand, he must protect the gentle and kind-hearted Kanae, and on the other hand, he must heal the hatred in Butterfly's heart. Walking in the cruel world of ghost slaying, I tried my best to let my sisters live a good life.
