This was the day that Tanjiro and many other Demon slayers have been waiting for... the downfall of the demon king, Muzan Kibutsuji. But imagine everyone's surprise when Lady Tamayo's poison turns the demon king into... something else.

I'd advise people to read this before reading the story since I'm changing some things:
In the fight with Muichiro and Gyokko the fight lasts until sunrise where both characters are still alive, Gyokko manages to get away when the sun rises. (In short Gyokko is alive in this story.)
Zenitsu doesn't exist in this story because... I don't like him.
Kagaya will be out of character for comedic purposes, I wanted to change his personality for fun.

That's pretty much all, I'd also like to apologize for taking so long to finally write this, I've had major Writer's block.
Also the cover was made by me, if anyone cares.
