Kazutora is a playful demon prince. He was doing business in the human world with a couple of his friends when he saw you.

You are an angel. He knew that you were enemies, but you still charmed him and he decided to follow you. It has slowly become his daily routine to watch you in the sky among the clouds. Once, when you were packing the books in the main house, you heard a sound. Something fell. You went to see it.
