Bloodline Paradox: Silver and ShadowsEpisode 19

Hunter Elias has hunted the vampire Lorian for three hundred years, convinced he is the one who killed his parents. In a fatal ambush, Elias — the ace hunter — is forced to form a desperate alliance with Lorian, the vampire noble. As they trace the conspiracy, he tears open the cruelest truth: his adoptive father Stone, the guild director whom he revered for half his life and who raised him, not only colluded with the vampire progenitor to launch the human-experiment "Project Zero," but is the true culprit who killed his father with his own hands and destroyed his family! The false upbringing was a scheme long in the making. Racial hostility, a blood feud, and forbidden love intertwine layer upon layer, as two mighty rivals join forces to break the deadlock, defy fate, take their revenge, tear apart the hypocritical mask, and guard the one redemption and the road home.
