One the Mangafox website there is one shot title called Mana Sorcerer. What I am proposing is for those who want to take this up to go read Mana sorcerer and create a crossover between Naurto and Mana Sorcerer where:
Naurto is banished after the Valley of the end by the council and he leaves the Elemental nations. 2-3 years later the village sends a team to bring him back to the village for a reason of the author's choice. What they find is that Naruto has become a Mana Investigator and doesn't want to go back to the place that betrayed him. This would center on the team's efforts to bring him back and if he does go back how it affects the Shippuden timeline.
Naurto finds an old book that explains about Mana, how it works, and how to use it. This can start pre-series, the Forbidden scroll incident or during the month of training before the Chunin exam's 3rd round.
Point for all those reading this, Mana is not the Mokuton. It runs with a different energy then chakra so any training from Tenzo would be useless outside of ideas of new uses for Mana. Also there will be none of the following
Naurto X any male character pairings, this just seems nasty to me, you are allowed to change someone's gender for this though
God-like Naurto, sure those stories are fun to read, but all power Naurto gets in the stories he works his butt off for and is reasonable.
Over the top bashing, all bashing in the story, if there is any, must be tasteful, so no Sasugay or Pink Banshee lines. If you what to bash somebody go ahead, just be reasonable about it. Oroichmaru however is free game for all forms of bashing, so go wild on him.
Evil Naurto, just doesn't fit what I see a Mana using Naurto being like, sorry if you like that kind of thing.
