Shinobu is a petite young woman with a pale complexion and large, compound-like eyes that lack pupils, only a haze of gradient purple, making her eyes appear similar to those of insects. Shinobu displays a bright, friendly and cheerful demeanor, always having an easygoing smile on her face regardless of the situation she is in. However, her outward behavior is shown very quickly to be a façade. This is displayed in the way she enjoys teasing others.
