A plot twist could be that the person who hired Naruto to save the princess is the real villain. They want to use the princess's power for evil once Naruto brings her back. Naruto figures this out just in time and has to protect the princess from the very person who sent him on the mission. He then has to find a way to stop the bad guy's plan and keep the princess safe at the same time.
