Ninja Nonsense

Kaede, a high school student, is studying for exams when her concentration is disrupted by Shinobu, a ninja-in-training, who's trying to complete a task that requires her to steal one of Kaede's undergarments. This unexpected situation leads to the formation of an unlikely friendship between the two girls as Kaede gets drawn into Shinobu's life. Kaede's introduction to Shinobu's world includes partying ninjas and Onsokumaru, a yellow creature resembling Pac-Man who claims to be the supreme ninja master.
