Russia, a dragon and America, a prince used as a human weapon of the military. In a world where everyone has abilities, after Russia tried to assassinate the prince, America made the outrageous request of wanting Russia, a murderer, to be his guard. 

Although the prince seems more than capable to protect himself. 

The Russian hates the prince's guts, constantly trying to kill him but failing. A slow burning romance brewing along with a bloody future.
