Lady Agniet (Anna Robert Agniet) is a High Mage and Rosen's mentor for ten years. She is a beautiful woman of twenty-eight, with bright violet eyes, a simple but elegant Saint's hairstyle, and a well-tailored bright purple silk dress. She is wealthy and generous but strict with her apprentice. She is fair in her tuition accounting and allows Rosen to graduate despite his debts, showing a softer, kind side beneath her stern exterior.
