Noire Foschurose is a ten-year-old noble girl who resides in the town of Crimonia. She is often called Noa, a name she prefers over her full title. Her father, Cliff Foschurose, serves as the lord of Crimonia, and she lives with him in the family mansion, while her mother, Ellelaura, and her older sister, Shia, live in the capital. Noire has blonde hair and blue eyes and is typically dressed in frilly noble attire, though her refined upbringing often gives way to an exuberant, childlike personality when bears are involved.

Her defining trait is an overwhelming love for all things related to bears. This obsession began after she witnessed the protagonist, Yuna, using her unique bear-themed magic and items. Noire treats Yuna as a personal hero and formally declares her a rival for bears. She enthusiastically runs the Miss Bear Fan Club, a group dedicated to celebrating bear-related topics, and frequently drags her friends, including Fina and Shuri, into adventures that involve bears. Her excitement often overrides the decorum expected of a noble, and she approaches even serious situations with infectious warmth and chaos.

In the story, Noire serves as a supporting character who provides comic relief through her energetic fixation on bears. Her role strengthens the group’s bond, as she acts as a catalyst for fun, lighthearted activities and helps others embrace the whimsical side of Yuna’s powers. Despite her young age, she shows a degree of independence and loyalty, often rallying those around her to support Yuna’s endeavors. While she possesses no special combat abilities or magical skills, her enthusiasm and social influence make her a valuable presence in the community. Over the course of the series, Noire becomes more confident in her own identity, balancing her noble responsibilities with her free-spirited passion for bears.
