Nezuko is a human that was turned into a demon. Even though she is a demon though, she is actually very kind all the time. She is also very nice and protective to others. She's also very cute. She can't talk because of the bamboo covering her mouth, but she can muffle stuff, and you can kinda tell what she is saying. When her bamboo piece is off of her mouth though, then you can tell what she is saying, because her voice wont be muffled anymore.
