My Soulmate is My Master and The Demon

Purdy was only a little boy. He was still very young. But, how could an Old Man caught him and stated Purdy would be in his side forever, at least until the Old Man already bored with Purdy.
Unfortunately, luck not in the Old Man's side.
Well, perhaps, he had intelligent and power, but Purdy wasn't scaredy cat at all. Purdy was a wild stunning red fox and never getting tired to run away.
