Aziel is a rare species of a black cat. Being half human and half cat makes his appearance weaker and submissive. Some locals decided to capture him and in attempt of selling him for high price, they sent Aziel to a famous bidding centre where only millionaires and above could afford. The bidding centre were always full of exotic animals or even humans, like Aziel, rare items and species. Those animals and humans were sold for high price — the same goes to Aziel soon.
