you probably heard about Tanjiro Kamado. a bright boy who always had a smile. now all you hear is rumors of how he tried to kill Master. he's missing. nobody knows where he went not since the serpent hashira killed his demon sister. not only that but the mist hashira also disappeared. where did they go?

What if Muichiro survived the final battle? I posted this on my ao3 awhile ago so might as well bring this here too <3
