Dragon King

Ouryuu (応竜) is the final guardian beast set to appear to prevent the assimilation of the world. He is brought forth from the being with the most fragments of the Dragon Emperor. But in the Web Novel, the worlds merged before he was awakened from Gaelion, so there was no longer a reason for him to awaken and rampage like the other beasts to complete the Wave Barrier.
