The ninjas of Japan, who once thrived during the Warring States and Edo periods, were forced to disband their organizations due to defeat and seemed to vanish from history. However, in reality, as many as 200,000 ninjas still secretly exist, monitoring events from the shadows. The unremarkable Kuga Kurogane (voiced by Sakai Taito) spends his days barely alive at home, appearing to be a complete loser, but he is actually a ninja with extraordinary skills. One day, his superior, posing as a delivery person, comes to his door and assigns him to fight against his arch-rival's ninja squad at a certain high school. After being dormant for too long, Kuga is finally awakened by the organization, but this mission is just the beginning of a series of major events… This film is adapted from the manga of the same name by Kengo Hanazawa.
