Ninja Cadets

Two ninja clans, the Byakuro and the Kabusu, are at war with one another during Japan's feudal era. Then, one night, the Kabusu mount a ferocious assault on the castle of Byakuro in an effort to seize the clan's young princess. When a Byakuro ninja leaves the attack with the princess and vanishes, later training her to be a ninja, their plan is thwarted. Six ninja trainees are assigned a mission to sneak into the Byakuro castle when it is being held by the Kabusu in order to complete their training years later. But when they come across three Kabusu members who employ evil sorcery in an effort to once more kidnap the princess—who also happens to be one of the trainees—their abilities are put to the test.
