Kimetsu no Yaiba Novelize

As long as anyone can remember, there have been rumors of man-eating demons living in the woods. Even in the more enlightened Taishou era, the townspeople never go near there at night. Tanjirou Kamado, a kind boy who has been supporting his family as a coal seller since his father died, quickly learns that the local superstition is more than just rumors when he returns home one day to find his family slaughtered by demons.
