The man named Marco Adriano is a loyal and beloved member of the Cristiano Family, helping them protect the persecuted Twilight population in the city of Ergastulum. But he was once a boy code-named "Spas," raised as a Hunter and assigned to the Destroyers Second Group for a single purpose: to track down and kill Twilights. After making the fateful decision to defy his fellow Hunters and save a young girl's life, Spas finds himself caught between the worlds of the Normals and the Twilights. Branded a traitor by the Hunters, yet still considered an enemy by all the other factions, he's on the run and desperately trying to find his way through the carnage and chaos that surround him.
