The protagonist and narrator of the story. She is the eldest daughter of Viscount Daniel Weltin and the de facto manager of the Weltin Merchant Guild, which holds the exclusive trade of magic stones. Overworked and sleep‑deprived from handling all the guild’s paperwork, she is forcibly recruited by Princess Julianne as a maid. Initially anxious about her lack of noble manners and uncertain about her future, she gradually thrives under the princess’s management, gaining better rest, improved health, and even a territory of her own. She is blunt, hardworking, and deeply loyal.
