Ninja Cadets - S01

During Japan's feudal era, two ninja clans, the Byakuro and the Kabusu, were at war. One night, the Kabusu launched a fierce attack on the Byakuro castle, hoping to kidnap the clan's infant princess. Their plan failed when a loyal Byakuro ninja escaped the attack with the princess and vanished, eventually raising her as a ninja. Several years later, six ninja trainees are sent on a mission to infiltrate the Kabusu-occupied Byakuro castle and retrieve a sacred scroll to complete their training. But their skills are put to the test when they run into three members of the Kabusu, who use dark sorcery to try once again to capture the princess, who happens to be one of the trainees.
