Okay so there's been a lot of speculation on what "one piece" is and everyone has their own theories. That's great, but I want to ask a more important question. What do you WANT it to be? What ending would you deem appropriate for the series that would give you closure? What would wrap it up perfectly for you so there's no further want or need for continuation? Personally, I think there will be a little bit of everything for the crew that survives. I think there will likely be at least one casualty leading to Raftel and upon reaching there the adventure will end.
Anyway, enough of what I think or want. What do you want One Piece to be and how do you want it to end?
