Demon Slayer: My Sister Is a Top Stringer

I woke up from a four-hundred-year sleep, and the world has changed. My name is Sakuya, a former samurai, now "Xiaozhu". The only reason why I joined the Demon Slayer Corps was to find her - my sister, Asuka Chizuki. She was my whole world, she picked me up from the corpse of a troubled world and gave me a name and a home. But she was reduced to a ghost and became the upper string under the command of Onimai Tsuji Mukai. That night, her smile pierced my heart. The most cruel and tender cage was woven for me with the vampire magic. "Go to sleep, Sakuye. There is no more you or me in this world." The Lord said that the goal of the Demon Slayer Squad is to eliminate all evil spirits in the world. Qiang Rabbit asked me why I showed mercy to the ghost. Kanae saw through the struggle between my blades. I can't answer. When the Immortal Visit envelopes me again, when her blood ghost technique collides with my breath of dawn in the air—— I know that I must use this knife to cut through Dawn, and personally cut off her despair in the name of love that has lasted for four hundred years. ——I want to ask her, in this cursed eternal life, have you ever lived for yourself for one second?
