One piece the treasure that is so important that everybody search for it and the manga is named after it. What is it?
I think one piece is the final poneglyph with the key to the lost era.
What in my opinion is that the world gov destroyed the ancient kingdom and everybody with a D. in there name is a survivor of that country.
And after knowing that true Luffy will together with his friends he meets along the way destroy the world government.
Or he will decide to do the same as Gol D. roger and just ignore the it because he wants his freedom, although i don't see Luffy as that kind of character.
What do you think?
