In a world where evolution went wrong, beasts mutated... oceans awakened... and ancient demons returned.
The human race is no longer at top of the food chain.

When heavenly Blood Rings drop down, chosen humans receive the ability to capture and control monsters, although no power comes without a cost.
Zyric, a common boy from the lowest zone, finds a forbidden ring... a ring that the demons are afraid of.

With the fall of the kingdoms, the jungle tribes emerge, the ocean guardians awaken, and alien civilizations observe Earth, a brutal era begins, the Era of Beast Lords. 

To survive, he must hunt.

To protect, he must evolve.

And to rule… he must become something no human has ever been.

A demon tamer.
