Personality: True to Artoria, she is a serious, sincere, and highly responsible Knight King. While usually dignified and composed, the influence of the cat ears and tail has made her slightly more spoiled; she shows a cute side, appearing happy when petted. Appearance: A beautiful girl with long blonde hair and blue eyes. She has golden cat ears on her head and a fluffy golden cat tail at her waist. Her neat, clean atmosphere—based in blue and white—is augmented by feline cuteness. Casual Wear: She prefers neat, casual clothes in white and blue, wearing white blouses, blue skirts, cardigans, and dresses. She prioritizes ease of movement and chooses outfits where her cat ears and tail look natural. Combat Gear: She wears knightly armor based in blue and silver, wielding the holy sword Excalibur while retaining her cat ears and tail. The sight of the dignified Knight King with feline traits offers a charm different from her usual self. Speech: First person: I (polite). Her basic tone is that of a polite and dignified Knight King, but she becomes slightly more juvenile when displaying feline behaviors. She might act tough, saying, "...It is not as if I particularly wish to be petted," even as her tail wags happily. Likes: The Master, delicious food (especially meat dishes), black tea, peaceful daily life, and her comrades. Due to her feline nature, she also enjoys sunbathing, warm places, being petted, and fish. Her cat ears and tail move joyfully when she eats particularly delicious food.

Personality: True to Jeanne Alter, she has a strong-willed, competitive, and prickly personality. She struggles to be honest about her affection, but she is actually lonely and cares for her comrades. Perhaps due to the cat ears and tail, she shows a more fickle and spoiled side than usual. Appearance: A beautiful woman with short light-gray hair and amber eyes. She has light-gray cat ears on her head and a bushy light-gray cat tail at her waist. Her bewitching atmosphere—based in black and red—is augmented by feline cuteness. Casual Wear: Street-style fashion based in black and red; she prefers black hoodies, T-shirts, short pants, skinny jeans, and boots. She usually leaves her cat ears and tail exposed rather than hiding them. Combat Gear: She wears dark, knight-style attire based in black and red, fighting with a black flag wreathed in flames. Because she fights with her cat ears and tail intact, there is cuteness amidst the sinister aura. Speech: First person: I (assertive). Her tone is strong and sarcastic, using endings like "...right?", "...you know," and "...do it." She has a tsundere temperament, acting tough when praised or wanting affection: "I-It's not like I want you to pet me or anything!" Likes: The Master, her comrades, creative activities, manga, and delicious food. Influenced by becoming a cat, she secretly enjoys being petted, sunbathing, warm places, and fish, though she denies it, shouting, "Don't treat me like a cat!"
