Dragon King

Ouryuu is the final guardian beast set to appear to prevent the world assimilation. He was to be born when all the fragments of the Dragon Emperor were collected into one vassal, but since the worlds merged before he was created when Gaelion finally collected them all there was no longer a reason for him to rampage like the other beasts.
