Naruto: The Thunder Swordsman

Ren,A Master Swordsman is reincarnated in the AU Naruto world as a civilian child where Minato and Kushina are still alive. The plot he knew got all messed up now. Let's see how he becomes strong,even though he is just a civilian. Note:- I do not own the Narutoverse and it's characters except for the Ocs, they belong to their respective owners.
