[Demon Slayer] Koike's Taisho Adventure~

After staying up late and dying suddenly, Sanriyuechi traveled through time. She came to Demon Slayer: Kimetsu no Yaiba, where she had just finished watching the anime and following the manga before she died. In addition, it may be because he was still hanging up Arknights before he died... An [Arknights System] appeared in her mind as a golden finger. "——I can! I can!" "Next, I'm going to punch and polish my head and step on my head!" "Marry the eldest brother, get rid of Wuhan, and reach the pinnacle of life!!!" (Cough) # Notes 1. CP is the eldest brother 2. The heroine uses the system of Arknights (a mobile game). If you have never played the game, you can read the game and write down some game-related knowledge. 3. A growth-oriented heroine who is a complainer, but may actually be a little bit more mainstream...? Not Su Wen (maybe Su Yisu will be in the end) 4. It's private and OOC. The timeline may be fine-tuned, but generally it won't change. 5.——Of course everyone survives! ! 6. Can play all kinds of weird tricks... (Escape) 7. If you don't like it, please comment... I'm eager to comment! Thank you! Purpose: Everyone survives——!
