Anna is a senior crew member on the Hagoromo airship, serving under Captain Saneatsu alongside colleagues Maria and the trio Addie, Betti, and Cindi. She possesses a headstrong determination that frequently surfaces as criticism towards Saneatsu's indecisiveness and leadership, driven by her deep commitment to the airship's operations and her expectations for strong command.

Her responsibilities involve ensuring the Hagoromo's daily function and mission readiness, bringing her into regular contact with the Kotobuki Squadron pilots and the airship's maintenance crew. During downtime, her working relationship with Maria extends to casual discussions about everyday topics like shopping.

In times of crisis, Anna's determination compels her to take charge and implement solutions, demonstrating leadership potential that moves beyond criticism to direct action. Her role remains centered on her professional duties aboard the Hagoromo, her interactions with the crew, and her defining traits of assertiveness and critical assessment within its operational framework.
