In feudal Japan, two forces--the virtuous Byakuro and the evil Kabusu--are at war. One night, a group of Kabusu ninja brutally attack the Byakuro castle. Their objective? The infant princess of Byakuro, who is said to have within her a power beyond comprehension. The child, ignorant of her past, is sent into hiding and raised as ninja. Years later a group of young Ninja Cadets, including the now-grown princess, is sent on mission to retake Byakuro castle and find a missing scroll in order to complete their training. Sakura, Pochi, Matsuri, Hayashi, Yume, and instructor Kaoru split into pairs and head into enemy territory. But little do they know that Kabusu assassins are tracking them, and they still want the princess...
