## One Piece Chapter 433, pages 4-5: The Name of the Sea - Chapter: 433 - Pages: 4-5 - Characters: Koby, Nami, Sanji, Monkey D. Luffy, Helmeppo, Dr. Vegapunk, Alvida ### Summary Page 4: Koby continues the lesson while Nami listens from the pool and takes notes. "ENERGY OF THE SEA... I GOT IT!" she says. The Kairoseki lets ships pass above Sea Kings unnoticed, and Koby says, "MILITARY SCIENTISTS ARE DOING A PRETTY GOOD JOB...!!" Sanji tries to enjoy the swimming pool, but Nami snaps that she is wire-tapping right now. The little exchange turns into worldbuilding: a technology hidden under Marine ships has changed how they travel through seas that terrified the Straw Hats. Page 5: Koby names the mind behind the technology. "THE MAN BEHIND SUCH AMAZING TECHNOLOGY IS NONE OTHER THAN DR. VEGAPUNK, THE MILITARY SCIENTIST," he says. Luffy recognizes the idea when Koby mentions the Devil Fruit he ate, and Koby explains that the transmission condition and ability of Devil Fruits, plus the technology to feed Devil Fruits to inanimate objects, are results of Vegapunk's recent work. Koby then looks back on the small world he once knew aboard Alvida's ship. He tells Luffy that until they met, he thought the sea he lived in was a small world, and jokes that if Luffy had not jumped out of the barrel that day, Koby would probably still be doing chores for Alvida.
