Yes, the Luffy going to be the princess's body guard is gonna be a treat. Also, athary, I was thinking along the same lines for Caribou and Sanji, and I think Sanji is going to be able to kick Caribou's Logia intangibility somehow, maybe by his intense heat of his legs like he did against Jyabura. Plus the three weakest obviously have changed to become true warriors as they stand badass surrounded and all. Usopp was badass and Nami looked stunning, and even Brook was taunting the opposition. GREAT chapter!
Also, did anyone else notice the StrawHats got new wanted posters/new photos of what they look like on the newspaper of the cover art? Look closely and you can see Luffy is pictured with his new wardrobe, Usopp's new white hat, Franky and his buzz cut, a portion of Chopper and his new hat with the X, Nami and her new hairstyle, and Brook with his crown.
Zoro, Sanji and Robin are bit harder to see but I do think they have new bounty photos/appearance photos alerting the world to what they now look like.
