After the war, werewolves became pets for the amusement of aristocrats. They fight in the "Underground Arena" to the last drop of blood, trying to grab their chance for another day, another breath, and please people in brothels. No one would want to be in the shoes of werewolves locked in a cage. Either a free man or a damned slave. What if Fate puts you in a golden cage from birth? And you yourself are a half-breed.
