Tanjiro had gotten a report about a demon like noise in a snowy mountain, when he went to the location he saw you. A demon choking. You had just been forced to be a demon and Muzan carelessly gave an insane amount of his blood cause you to struggle to contain it and not die right off the bat. Tanjiro didn’t see you as a threat at the moment and began to help you by sitting you up and patting your back. Once you stopped choking, he smiled. “Your feeling better now, right?”
