Bi-Vessel: Legendary Double Tamer

“I've seen terrors that no mortal should experience, but I can boldly say I'm your doom and messiah.” Darkness and light should never co-exist. But in this one, they surely will. Elio Ravina, a small boy from the world of beast tamers, should be innocent at this tender age, but he isn't. Before the Beast Contract Ceremony, he was a destroyer, a wreckage, a doom in flesh. He was the very signature of death. Where the world thrives with normal mana that supports life and the living, he carries matter that opposes life. Elio carried dark mana. But it was never his fault. His parents had been tricked into making a deal with a Dark Entity, and from birth, Elio was bonded to a beast that threatens everything living. He was bonded to a catastrophic, dark dragon. He became the vessel of darkness. But his tale won’t end this way. Elio will contract another beast from normal egg like everyone does. Again, luck proves to be against him. He thought it was over for him, until… ————~~~~~————~~~~~——— [User has successfully fused with the Bi-Vessel System.] [Beast bonds detected: Bloat Lizard and Abyssal Wyrmling.] [Dark Constituent Stability: 25%] [Your darkness is brewing.] ————~~~~~————~~~~~——— Granted an opportunity to restore what was lost and rectify this abysmal error, Elio is subjected to an eternity of maintaining balance and taming an untamable terror. Now, he has two beasts, two greatness. Darkness vs Light. Death vs Life. One must succumb to another.
