Fighting, Troublemaking, and Other Shennanigans

Suddenly, as Luffy and Shanks were talking, Luffy is suddenly struck with unbearable pain. He wakes up finding himself in the past and begins his life once more, but albeit going a different way about it along with everyone that came with him. And maybe some others joining in as well. Because why the hell not?

Adventures over the Grand Line, all four seas, and maybe even the Red Line take two?

And of course they all gotta mess the world up, just a little different than when they were youngsters.

They are just even younger now.
