Ninin ga Shinobuden

Kaede, a typical schoolgirl, is studying for her exams when she is interrupted by Shinobu, a ninja trainee who is trying to finish her own exam. In order to succeed, Shinobu must steal one of Kaede’s panties. As Kaede attempts to prevent the theft, an unexpected friendship develops between the two. Kaede becomes drawn into Shinobu’s world, surrounded by partying ninjas and a yellow, Pac‑Man–like creature named Onsokumaru, who claims to be the master of all ninjas.
