On How a Scumbag with Multiple System Hang-Ups Can Become a Boss (Demon Slayer: Kimetsu No Yaiba)

It is very easy to break the update. If it is not updated before September 2021, please consider it as abandoned. This story tells the story of an unusual female high school student who inexplicably fell into the world of demon slayer and struggled to survive with multiple system hangups. Because I have been tortured by comics and animations, the author will try his best to kick everyone's lunch (=^▽^=). The timeline is messed up because this article was written on a whim after reading a lot of large-sized articles. If there is any similarity, it is purely my fault. Thank you, but sometimes there may be similarities accidentally. I am really sorry. And since the author didn't finish the manga after watching the animation, because he couldn't find the resources in one issue, the characters may have a lot of OOC. Please forgive me. I am a new author, and this is also my first book. Thank you. I may not change it immediately because I need to do it bit by bit, but if you can point it out, thank you very much. If you can't accept the above, please leave. We'll see you again, thank you. There is no CP, at least not in this book, because Mumu wants to go to more worlds! Thanks for the above, and bon appetit! Purpose: May everyone be treated with kindness
