In this world, demons and humans coexist. Demons possess supernatural abilities called Blood Demon Arts. Some demons are weak, while the strongest serve as the Twelve Kizuki, divided into the Lower Moons and Upper Moons. Demons regenerate from nearly any injury and hunt humans unless they wish to turn them into demons. Only sunlight or Nichirin swords can truly kill them. The story takes place in the 1920s, but the characters react to future events through a television, The Lower moons who are Mukago, wakuraba, rokuru. All lowermoons are weak in comparison to uppermoons and often feel pathetic next to them, the lowermoons are nearly always dying to Hashira while the uppermoons practically hunt to eat Hashira, Muzan dislikes Lowermoons for their weakness, while he appreciates the uppermoons.
