Noiraud, whose name is also given as Kuroino and who is sometimes called Blackie or Bear Cat, is a large black cat that appears as a supporting character in the anime Chi's Sweet Adventure. His physical size and dark coat give him an imposing, almost bear-like presence, which initially frightens the kitten Chi when they first meet. Despite this formidable appearance, Noiraud quickly reveals a gentle and patient nature. He takes the young Chi under his wing and becomes her first true feline friend, serving as a mentor and father figure. His primary motivation is to guide Chi toward becoming a real cat, teaching her essential feline behaviors, survival skills, and the ways of the outdoor world. He does this with calm patience, even when Chi's playful energy is overwhelming. In the story, Noiraud acts as a protector and a source of wisdom, helping Chi navigate situations where her human family cannot follow. His bond with Chi deepens over time, transforming from wary encounters into a relationship of trust and mutual affection. Noiraud also has a history of living as a neighbor in Chi's old apartment, though he eventually had to move. His notable abilities include his physical strength and his deep understanding of cat instincts, which he uses to keep Chi safe and to demonstrate proper cat conduct. Throughout Chi's Sweet Adventure, Noiraud remains a steady, caring presence whose gruff exterior masks a devoted heart.
