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, to the point of being rather sadistic about it. However, her outwardly calm and tranquil disposition is worn as a mask, as Shinobu holds an intense hatred for demons due to the loss of her sister and parents.
