As Luffy and Nami speak with him, the lion mink reveals more about the dark past of Sanji’s family, the Vinsmokes. He reveals that they are the leaders of the legendary Underworld army, Germa 66. This revelation expands the scope of the arc beyond a simple rescue mission, framing it as an integral part of the larger geopolitical conflict between Big Mom and the forces of the Vinsmoke family, a conflict that will define the next saga of the series.
What makes Episode 765 stand out in the Zou Arc is its focus on the psychological recovery of the Minks. We see the Straw Hats acting not just as liberators, but as caretakers.
