Fuu is a gentle-looking girl with chin-length sandy blond hair, short bangs framing her face, green eyes, and round glasses that give her a calm and intelligent appearance. Her composed demeanor is often reflected in her graceful and thoughtful expression, hinting at her analytical and kind nature.

She wears three main outfits throughout the series. Her school uniform consists of a green jacket with a white collar, a green skirt, a white petticoat, a small red bow, and a matching headband. Upon arriving in Cephiro, she receives white and gold armor adorned with emeralds. When her armor evolves to its final stage, she dons a green armor dress with a skirt designed in a feather-like pattern, complemented by a gold belt set with an emerald and white shoulder armor shaped similarly to her skirt. Her gentle and elegant appearance reflects her composed and caring personality.

Fuu is always seen with a gentle smile and carries herself with calmness and politeness, though she can be surprisingly blunt at times. Her background in her school’s archery club makes her skilled with a bow and arrow, which becomes her first weapon as a Magic Knight. Later, she acquires a large sword made from Escudo, a powerful weapon that becomes impossibly heavy for anyone other than her to lift. Her composed nature, combined with her precision and focus, makes her both a reliable teammate and a formidable fighter.

One of Fuu’s greatest strengths lies in her intelligence and ability to strategize logically under pressure. From the very beginning, she remains level-headed and thoughtful, choosing to assess situations carefully rather than panic. She has strong morals and a deep curiosity, as shown when she hesitates to intrude upon Presea’s home but eagerly observes her surroundings once inside. Her intelligence leans more toward “book smarts” than “street smarts,” and her tendency to state the obvious often amuses or frustrates Umi. Despite moments of self-doubt, Fuu’s faith in herself, her friends, and their shared mission helps her stay strong. She shares a deep bond with Ferio, the estranged brother of Princess Emeraude, and their relationship grows closer as the story progresses. Even after learning of the painful truth about his sister, Ferio’s affection for her remains unchanged. In the anime’s second season, Fuu showcases her skill by winning an archery contest against Lady Aska, after which the two become good friends.
