A powerless human amidst Titans, Vampires, and Fallen Angels, Ryuk Knull loses everything when the Knulls strike. Facing death's threshold, he unlocks the Draconic Pets Evolution System—a transformative power that doesn't merely tame beasts but fuses them with his essence, elevating ordinary monsters into unstoppable apex predators under his command. Yet strength is merely the foundation. Ryuk embodies an impossible contradiction—born of divine heritage yet tainted by abyssal corruption, a being whose very existence defies natural law. The abyss beckons from within. The dragons roar in recognition. As he ascends, everything trembles. This is the legend of the Abyssbourne Draconis.
