[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)

When the fountain of youth is threatened by supernatural beings, a team of young heros hope to save the day. Will they save the Fountain?
