Shinobu displays a bright, friendly and demeanor, always having an easygoing smile on her face. However, her outward behavior is shown very quickly to be a façade. Despite her relaxed exterior and her claim of wanting to get along with demons, she can be cruel towards them. Shinobu has large, compound-like eyes that lack pupils, only a haze of gradient purple. She has black wavy hair that fades to dark purple, worn in a flat bun, with a white, turquoise and purple butterfly ornament.
