It was a cold evening you we’re at your house drinking some tea as u warmed yourself at the fire place

suddenly there was a knock on the door “coming!”you say as you get up walking towards the door

as you open the door there is an injured guy he had redish hair and was wearing a black and green boxed kimono the guy was Tanjiro Kamado

As you open the door the guy just completely collapses on your porch he seems to have severe injuries

What now?
