Koby fills Luffy in on the New World and a brilliant scientist named Vegapunk, the crew throws a sprawling celebration, and far away two Emperors edge toward a meeting that puts the World Government on alert.
Garp chooses to free Luffy on the grounds that he is family and plans to cover the decision when reporting to the Marines, though Bogard suggests simply saying the boy slipped away. Outside, Koby describes how Marine vessels manage the Calm Belt: Seastone is laid along their hulls, a mineral that gives off the same aura as the ocean so that Sea Kings pay them no mind. He attributes the invention to a brilliant researcher named Vegapunk, and Helmeppo adds that the scientist has even worked out how to load Devil Fruit powers into objects. Eavesdropping by the pool through a black Den Den Mushi, Nami listens in. Koby names the waters beyond the Red Line the New World, reached to its end only by the Pirate King, and departs as a future rival.
The crew throws a huge barbecue that pulls in the Franky Family, the whole Galley-La company, and Iceburg, with Sogeking leading a song. Apart from the revelry, Robin hears Aokiji's voice asking why she did not run this time, and she answers that she could no longer stand by and watch her friends die. He explains that Jaguar D. Saul had been a close friend, and honoring what Saul once wanted, he means to see how her life turns out. Aokiji tells her to keep living because Ohara endures within her, then disappears before she can chase him down. The chapter ends at Mary Geoise, where a member of the Five Elders learns that Shanks and Whitebeard have made contact, as Whitebeard greets Shanks aboard demanding he brought decent drink.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

When I first decided to commit to watching One Piece seriously, I knew I was embarking on one of anime's longest and most beloved series. With over 100...
The scientist Vegapunk earns his very first mention here, and Koby explains both the New World and the Seastone-fitted ships that traverse the Calm Belt. Contact between Shanks and Whitebeard puts the World Government on edge. The cover continues Enel's lunar journey as he comes upon a lifeless body in a uniform inside a hole.
In Chapter 433, titled The Name of That Sea Is, Koby explains that the waters beyond the Red Line are called the New World, a region only the Pirate King has fully explored.
Vegapunk is a brilliant scientist first mentioned in Chapter 433, credited by Koby with inventing the Seastone-plated Marine ships that cross the Calm Belt safely and with finding a way to store Devil Fruit powers inside objects.
According to Chapter 433, Marine ships are lined with Seastone, a mineral that mimics the ocean's aura so that Sea Kings ignore the passing vessels.
Aokiji tells Robin that his old friend Jaguar D. Saul wanted to see how her life turned out, and he encourages her to keep living because the will of Ohara endures within her.
Chapter 433 ends with a member of the Five Elders learning that Shanks has made contact with Whitebeard aboard his ship, an event that worries the World Government.
