Summary
Tanjirou rejects Saburo's offer to stay the night in his house and heads home. Before he gets there he's attacked and loses consciousness. When he wakes up he doesn't remember anything but that he must go somewhere. He goes where he feels he must go and when he gets there he smells human. His curiousity makes him go to the house where he smells humans, but before he can get inside, a child runs up to him screaming something he can't understand. It takes one look at the child to remember. It's his little brother.
Or Tanjirou heads home instead of sleeping at Saburo's and bumps into Muzan who transforms him into a demon. Demon Tanjirou is cutie patootie Tanjirou.
