Long story short, Dave was a guy who everybody looked up to he was the richest man to live he was a scientist who made the cure to cancer but then he died, and got a chance at a second life, but this life is more interesting as he gets to travel to Anime worlds while in the process getting stronger as he is the Successor of THE GOD and for that to happen he needs to be strong. I don’t own Naruto all credit to that goes to their creator. All I own is the MC.
