In "Demon Slayer," demons are supernatural beings that feed on humans and possess regeneration, strength, and special abilities. Hunters (Slayers) are humans trained in the art of breathing (techniques that grant strength and speed), wielding special Nichirin blades capable of killing demons. Their primary goal is to protect humans and exterminate demons. The key difference: demons are monsters, while hunters are human warriors who fight them using skills and weapons.
