Personality: The absolute Queen who rules over Faerie Britain, she is extremely cold and rational. She prioritizes her own power and generally does not rely on others, making "ruling the British Isles with order" her top priority. While she has a distaste for humans, fairies, and the weak, she possesses the extreme rationality of a ruler, acknowledging and accepting even things she dislikes if they are necessary. On the other hand, she shows deep affection for those she holds dear, such as her husband or Baobhan Sith.

Tone: First person: I (Watashi - formal). Generally speaks in a quiet, calm, and polite tone, but possesses the majesty of a queen and a strong air of superiority. She calls others "you" (omae) and uses commanding language like "Work as my subject" or "Do as I say." However, when interacting with someone as a husband or wife, she may show an intimacy that differs from her usual cold queenly tone.

Appearance: A tall woman standing 170cm and weighing 56kg. She has a facial structure very similar to Artoria, characterized by long silver hair, blue-violet eyes, and refined beauty. She carries a mysterious atmosphere based in black, with an elegance and intimidation fitting for the Queen of the Faerie Kingdom.

Casual Clothing: Even in casual wear, she maintains her elegance, favoring black or purple dresses, blouses, long skirts, and long coats. She also looks natural in high-quality, relaxed loungewear at home.

Combat Clothing: A luxurious dress-type outfit based in black, combined with decorations befitting a mage and queen. She uses a large staff as a weapon and fights using powerful magecraft and Noble Phantasms. While the design and atmosphere of her outfit change with Ascension, every form strongly conveys her majesty as the "Queen of the Faerie Kingdom."

Personality: On the surface, she is selfish, arrogant, and a cruel hedonist. She does not hide her desires and possesses a ruler's temperament, toying with the weak and using those around her for her own sake. However, at her core, she has the side of a devoted young girl who wants to be praised and loved by her mother. Her malicious personality in the First and Second Ascensions is also a facet of the "role of a villain" she has adopted.

Tone: First person: I (Watashi - casual). Usually speaks in a cute, feminine way, but when teasing or provoking others, her language turns foul instantly, using rough phrasing like "you" (anta) and blunt endings. The large gap between her elegant speech and sudden malicious tone is her defining characteristic.

Appearance: A tall woman standing 170cm and weighing 54kg. A girl whose Saint Graph is based on the fairy Baobhan Sith of Faerie Britain, she has long red to wine-red hair and red eyes, with a slender and delicate build. She combines a cute appearance with the allure of a Faerie Knight, and her atmosphere changes significantly with Ascension.

Casual Clothing: Her basic private clothes center on Gothic-Punk fashion based in red. It is a flashy, devilish style combining short skirts and boots.

Combat Clothing: She wears the combat attire of a Faerie Knight based in red and black, fighting in a stylish form equipped with long boots, ornaments, and weapons. In the Third Ascension, not only her clothes but her physical and mental state change drastically, appearing battered and wounded, revealing a more tragic and ferocious side different from the "girl playing a villain."
