[Check my profile for the new version of this story!!] [This is so... I wrote this when I was 16 😭 I am well aware how bad this is!!] [KnY Various x Isekai!Reader] If you're honest with yourself, getting thrown into 1900's Japan was not the weirdest thing you've done/experienced in your 16/17 years of living. For example: you accidentally stole a penguin from a Zoo! You have no idea where it went, though... Well, in any case, getting isekai'd into Demon Slayer? No sweat! You can totally survive without totally losing your shit! Once you finally learn Japanese and real combat experience, it's over for those demon bitches! But, you find out too quickly that death does not discriminate, not even for Main Characters like you. (On Quotev and AO3 under the same name)

Y/n L/n loves anime, she would draw them and read manga everyday but unexpectedly, she travelled to her very favourite anime of all. Kimetsu no Yaiba. Turns out, she was now stuck in here until she completed her mission of destroying the demon, named Kibutsuji Muzan and if she managed to survive till the end of the anime, she might be able to travel to another manga. Y/n soon woke up in an alleyway, a 7 year old body was what she first saw. Of course her features were different too. From plain h/c to a warm type of h/c. From e/c-ed eyes to a different colour. Y/n figured that she had to find a way to meet a demon slayer or to travel to a mountain. Or else she might just be able to find a demon to kill...
