The Secret of the CastleEpisode 4

Sylvia, who possesses the rare AB-negative blood type, was lured by a fraudulent charity into the clutches of Elias—a vampire who had lived for four centuries and kept her captive to harvest her blood for his own survival. After she and her companions managed to severely wound him using silver dust, they escaped and alerted the authorities, bringing the horrific ordeal to light. Following Elias's escape, Sylvia established a protective network for women with rare blood types to track him down; she ultimately cornered him in an abandoned church and slew him with a silver blade. For the rest of her life, she dedicated herself to safeguarding vulnerable women, transforming her own trauma into a source of hope for others.
