Tomorrow's Romance Dawn

The Straw Hats have left Drum, ready to take on Baroque Works in Alabasta. However, upon making a pit stop at a fog-covered 'mystery island', they come across something they never expected to find, even on the Grand Line: an older Zoro! Now they must locate the rest of the future Straw Hats, as well as keep an ancient treasure out of the hands of bounty hunters.
