[Protagonist has no cp] [HE] [ooc apology] (The text has been completed) Updated movie viewing and extras Shu Yu traveled through time and the ghost was destroyed. Because the system gave her too much, she decided to complete the task of changing the past of Nine Pillars and Liu Xiaozhi. And help them defeat Wuhan. This time they won't be stuck in the past, they will have a happy future. Facing Kotonoha's husband and mother-in-law, Shu Yu "robbed!" Seeing the conflict between the Immortal Kawa brothers, Shu Yu exposed Shimi's background to Immortal Genmi, "Believe me, your brother loves you so much." A certain brother-in-law immediately got angry. When Shu Yu faced the dishonest man who was talking about Mi Li, he came up with explosive output. Shu Yu came to Tanjiro's house and took Nezuko out for a trip and discovered the blue Higan flower. After changing the past, Shu Yu began to help them change the future. Whatever is dead will be given life to me. The Demon Slayer Team ushered in the most prosperous battle. Shu Yu pointed to a dozen pillars in the yard and said to Ubuya Shiki Yaoya: "Look, this is the country I have built for you." In the process of getting along with Shu Yu, everyone gradually fell in love with this girl with a weird personality but a kind heart. Later I will write about the visual aspects of humans and ghosts.
