Here's a plot it's the first one I'm thinking of. Naruto and the other rookies along with their sensei, the konhamaru corps along with Jaraiya and Tsunade all get taken to the future when Naruto is hokage. They are stuck there for one year. Naruto and the others learn what their future is like and the family they have. Using this knowledge and getting training while there when they return they must forge their own future and not make the mistakes of their past.
This is the second plot I'm thinking of. Naruto and the other rookies along with their sensei, the konhamaru corps along with Jaraiya and Tsunade all get taken to the past when Mito is still the foxes jailor and their parents are still kids. They are stuck there and must fight alongside their parents in the upcoming wars.
These are the plots I thought of but I might not have time to write them so I give you the people of this site permission to write out the story. After all the story is only the beginning.
