The four Ryudo brothers are descended from dragons - they have the speed, strength, and power of their legendary ancestors - and they're getting stronger.

However, these abilities make them all the more intriguing to Dr. Atsushi Tomozawa. The deranged doctor has gathered most of his twisted medical knowledge by dissecting living subjects.

Now the doctor is turning a hungry eye toward the unsuspecting Ryudo brothers....And this doctor wields more than just a skillful scalpel: his dissection experiments have produced a pack of cybernetic Dobermans. Even if they brothers can cope with this new threat, can they save their cousin?

Something bigger is going down, and the doctor is only a pawn. America's most powerful business consortium is focusing its attention directly on the brothers and their abilities. Can the descendants of ancient and powerful dragons withstand a political influence that has toppled entire nations?
