Hi,
Maybe I missed some important part of the manga but I know that Log Poses are in use on the Grand Line but weren't needed on East Blue: do you think they'll still be needed in the New World ? That new ocean is separated from the Grand Line, except for the way undersea through Fishmen Island… maybe Fishmen Island and Marie-Joie are the last you can reach using a Log Pose ? If so, what's after ?
