I was wondering of a new Naruto Movie that returns to the original era. This movie opens with a kingdom being invaded by soldiers of the Empire of the Iron Sun. The soldiers include Ashigarus (musket soldiers), Yumis (archers), Imperial Warriors (swordsmen), and Naginata Warriors (cavalry). The princess and the queen flees the kingdom to the hidden leaf village. Four youths were fleeing the empire as they had lost their parents and friends at the hands of the Empire. They are: Hideki Nagano (a ninja who fights with balance with a sai and is the second lead character in the movie, first is Naruto), Ryoko Shirada (a ninja-priestess with a kind heart and fights with a staff), Takumi Shirahama (a ninja-samurai who fights well with a katana and wears samurai armor pads and body armor; he wears the armor in a way that limits loss of mobility greatly), and Shinzo Shirade (a dark ninja who is missing through most of the movie and is the brother of Ryoko). They were caught up by a gang of Naginata Warriors and were stuck down by them and left for dead. Later, the scene goes to the hospital, in a room with Sakura, Tsunade, and Hideki. Hideki then recovers and wonders where Ryoko, Takumi, and Shinzo are. He searches for them and finds a recovered Ryoko in a room with Shikamau. He then finds Takumi in a room with Hinata. He then enters the room and asks where is Takumi's armor and sword, believing that a samurai must always have both of these things. He later then meets Naruto. However, he finds out that Shinzo was never rescued and fears the worst for him. They then meet the queen and princess and ask to aid the village in preparation for an attack by the Empire of the Iron Sun. It's not long until they find the shadow warrior in service of the empire, Ryoko recognizes his voice and realizes that the shadow warrior is actually Shinzo, her brother.
