Ann, also known as Anna, fulfills the role of Lady-in-Waiting and Princess Catue's most trusted confidante. She idolizes Catue as a heroic savior, instinctively calling upon her during crises—a reliance highlighting Anna's fragility.

Following Dragundalla's invasion, she endures profound trauma: narrowly evading assault by the feral dragon King Lawrence thanks to Catue's intervention, only to later suffer non-consensual acts from Queen Nina, mentally manipulated by Guignol. This coercion results in Anna losing her virginity.

The anime concludes with Anna condemned alongside Dragundalla's surviving women to eternal sexual servitude in Guignol's monster army. Designated the "Final Girl" as the last woman psychologically broken by these forces, her ultimate condition post-breaking remains unseen in the bonus OVA.

Her portrayal incorporates fanservice without specific physical details, while her narrative purpose exemplifies systemic victimization in Catue's kingdom, devoid of individual development.
