Demon Slayer: Kimetsu No Yaiba: Mirror Flower Suigetsu

On a cold street in early winter, a young girl with amnesia was on the verge of despair amid confusion, hunger and cold, as if she was helpless and drifting in the snow, not knowing where to go. Until Butterfly House's Butterfly Kanae and Butterfly Shinobu appeared, the gentle concern and calm protection that penetrated the cold mist pulled her back from the abyss of oblivion and brought her to a warm haven called "Butterfly House". Here, she was given a new name "Butterfly Sanyixue". The Butterfly House is not an ordinary residence. Behind it is a secret mission to fight against ghosts. Kanae's gentleness, tolerance and calm professionalism not only build a safety barrier for Sanyixue, but also allow her to gradually find the meaning of existence after witnessing the perseverance and sacrifice of everyone in the Butterfly House. When the ghost's shadow quietly approaches, can Sanyixue, who has lost her past, get rid of her confusion under the light of Butterfly House, find her own way of fighting, and become a new force to protect this place?
