Angelica Rothschild is the princess knight of an elven kingdom, formally titled the Golden Princess Knight. She bears blond hair, green eyes, pointed ears, and a pale complexion, typically wearing attire that blends armored pieces such as spaulders and greaves with regal accessories like veils and hair ribbons.

As Queen Christina's daughter, Angelica belongs to the Rothschild royal family. Her kingdom enforces a strict hierarchy where elves dominate and humans face systemic discrimination as second-class citizens. This structure is exploited when the human Ernesto (El) plots to infiltrate the ruling class. Ernesto kidnaps and sexually assaults Angelica, then uses a magic recording orb to blackmail her into compliance and silence. Under duress, Angelica publicly declares Ernesto her rescuer, enabling his acceptance into royal circles.

Ernesto leverages this position to advance his revenge against the monarchy, using Angelica's coerced cooperation for political maneuvering. Ultimately, under Ernesto's influence, Angelica and her sisters participate in the murder of the elf king. This act secures Ernesto's usurpation of the throne. Angelica's narrative concludes with Ernesto's ascension to power and her implied role within his new regime, marking the loss of her autonomy and royal standing.
