Am I Beautiful?

Am I beautiful? I wear a white mask that covers my long disgusting tongue. Blood bubbles come from my mouth as I ask my question. My long black hair is covered in children's blood. I can see you shaking as you are lost at what the right answer is. My knifes swing side to side as I hold on to your warm body. For if you answer no to my question I will chop your head clean off. Foolish human, I used to be beautiful untill I died. You answer yes to my question and I will make you beautiful, just like me. Am I beautiful? This story is based of a japanese urban legend.
