Fimeko has short, messy brown hair that covers her eyes and an ahoge. She has light peach skin, and half of her face is severely scarred, and her eyes are milky white. She wears a dark magenta shirt with indigo frills on it, a purple, magenta and pink mini skirt, indigo shorts, light pink mary janes, a frilly choker, and a grape purple jacket-thing.
Fimeko is a stubborn, independent girl. She often denies help from others, and tries to do stuff on her own, despite failing most of the time. The only time she asks for things is when she asks what stuff looks like, since she cannot see it for herself.
