After seven years' imprisonment in the brutal Silver Crypt Prison, Aurelia Devereux returns to her vampire noble family. Framed as a scapegoat for her younger sister Celeste Devereux's fatal mistake, she bears all the blood guilt that never belongs to her. Her blood-bonded partner, Lucien Ashcroft, chooses his family's interests over their promise, leaving her drowning in betrayal and despair. As her ancient pure-blood power gradually awakens, Aurelia applies to the Nocturne Institute for a brand-new identity to cut off all ties with the Devereux family. Facing family prejudice, distorted affection, past trauma, and a hidden conspiracy, she abandons her original family name and grows from a hurt, longing girl into the powerful S-class Core Adjudicator Ria Nocturne. When the corrupted Eclipse Corruption breaks out and brings a huge disaster, she comes back not as a victim but as a judge to end everything. She finally breaks free from all blood-bond shackles and embarks on a life that truly belongs only to herself.
