Synopsis
During the war, a group of warriors known as the Ninku fought against the Imperial Army and nearly wiped it out. However, the Ninku ultimately lost and were scattered. After the war, the imperial army used propaganda to position themselves as the people's protectors and convinced the public that the Ninku were the villains who started the conflict. Fusuke appears to be a child, but he is actually the former captain of the first Ninku division. His mother was taken captive during the war, and after the Ninku's defeat, he sets out on a journey to find her. Along the way, he meets Aicho and Touji, both former Ninku captains as well, and together they battle the imperial army, which is trying to eliminate the remaining Ninku. The Ninku are a clan of extinct ninjas who command esoteric and powerful techniques, which is why many other groups constantly try to steal their abilities in order to take over the country. Their primary target is Fusuke, a strange-looking kid but one of the most powerful Ninku ninja. Fusuke, along with other Ninku ninja who have different specialties, must fight against the threats that led to the Ninku clan's downfall.
