Chihiro appears to be a young high school-aged teenager, but due to the memory loss, he is two years older than he believed. He has a small, lithe stature and doll-like appearance with short, light brown layered hair and hazel-colored eyes. He wears a girls' winter school uniform set, entailing a long-sleeved dark green jacket, a white shirt with a large collar secured with a thin dark ribbon, suspenders, a box-pleated, mid-thigh length brown skirt, knee-high black socks, and white Mary Janes.
