Shinobu is the star of the series. She is kind, hardworking, and dedicated, but naive and somewhat clumsy with complex tasks. She is usually charged with taking care of her dojo because everyone else is too lazy. She usually wears a purple and pink ninja outfit, but sometimes wears other costumes. Her ambiguous relationship with Kaede, whom she describes as "more than a friend but less than a lover", ranges from admiration and idolization to romantic interest. However, it seems that this may only be her own way of denying interest in Kaede, as she clearly exhibits a strong sexual desire for the other girl. Despite the influence of Onsokumaru, she remains fairly innocent.
