Set in Japan's Taisho era, the story follows a boy whose family is killed by a demon, leaving only his younger sister Nezuko alive—though she herself has been turned into a demon. He joins an organization dedicated to slaying demons, hoping to find a way to turn her back into a human, and fights man-eating demons along the way. The narrative centers on sword combat using special breathing techniques, the individual backstories of those turned into demons, and the relationships formed among both demon slayers and their enemies.

The series is valued for its focus on family bonds, particularly the relationship between the siblings, alongside a wide cast of distinctive swordsmen and demons and dynamic sword-fighting sequences built around breathing techniques. Even antagonistic demons are given personal histories and sorrowful circumstances, giving the work depth beyond simple good-versus-evil storytelling. With its large cast and web of relationships, it offers fan creators many characters and perspectives to draw from when reimagining the story.
