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 &quot;more than a friend but less than a lover&quot;, 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. 

Kaede is a normal school girl who was studying for her exams for school when suddenly she is interrupted by Shinobu, a girl who is a ninja-in-training, attempting to complete her exam. The problem is, in order for her to successfully complete her exam, she must steal one of Kaede's panties! 
In Kaede's attempt to stop Shinobu from stealing her panties, an unexpected friendship is forged between the two. Kaede soon becomes engrossed in Shinobu's world, surrounded by partying ninjas and a yellow pac-man like thing by the name of Onsokumaru, who claims to be the master of all ninjas!
