Shinobu is a petite young woman with a slender build and a pale complexion. She has purple eyes, black wavy hair that fades to dark purple, styled at the back of her head into a bun, fastened with a butterfly ornament. She displays a bright, friendly and cheerful demeanor, always having an easygoing smile on her face. However, her outward behavior is shown very quickly to be a façade. This is displayed in the way she enjoys teasing others, to the point of being rather sadistic about it.
