Uranborg

He's the King of Dragons, the special dragon among dragons. He's the King of all Beasts. He looks like a dark-haired teenager when he transforms into a human. His actual form is that of a dragon. His spirit magic level is the lowest among all the generations of dragon Kings, but because he has power called "Possession Magic" to call forth his ancestors, using his own flesh as the medium, he was chosen to become the King. He has the crimson Dragon Heart Sword which represents his essence. Being a beast from the Yin world he came to Yang world to find a person who summoned the beasts from their world to the human world.
