On March 10, Netflix dropped all eight episodes of ONE PIECE: Into the Grand Line, three years after the release of Season 1. As Zoro, Mackenyu will face off again “fiercer adversaries and the most perilous quests yet” in this season, along with his shipmates, as they continue their search for the world’s most valuable treasure.
