One Piece's Reverie arc has officially begun in the anime series, and one of the biggest highlights of this arc is that fans will be reintroduced to many characters they have not seen in quite a while. The last episode of the series even saw a return to Luffy's hometown, and even briefly revisited Shanks as he reacted to Luffy being dubbed the Fifth Emperor of the Sea.
