“The Count is a half-demon, a hybrid of a human and a devil?!”

After discovering the Count’s shocking secret, Sera is thrown out of the mansion where she faithfully served for ten years. Struggling to find a new path, she lands a job at the Inter-Species Protection Bureau, hoping for a fresh start.

Her new assignment? Caring for the Vlad Family, an aristocratic clan of vampires. Sera dreams of a peaceful life among non-humans—until she learns that the previous caretaker vanished after stealing the family’s prized heirloom, the Red Gem.

Now, the Vlad Family gives her an ultimatum: retrieve the Red Gem, or face the consequences.

By night, she cares for her supernatural charges. By day, she embarks on a desperate hunt for the stolen artifact. But as if that weren’t enough, a mysterious crown prince sets his sights on her, complicating her already chaotic life.

Can Sera survive long enough to uncover the truth and reclaim the Red Gem?
