Travel through the world of pirates. Before the battle in the Valley of Gods.

Rocks: "If it weren't for Ryder, I would have become the king of the world!" Edward Newgate: "My Shock Fruit is useless to him!?!" Garp: "Rocks was defeated by Ryder, and he deserves to be a "Naval Hero"!" Sengoku: "A man who developed Devil Fruit to the extreme!" Staff Officer Crane: "Ryder, I heard from Sengoku Garp and others that you can still absorb physical jutsu Haki? Is this true??" Ryder smiled evilly: "How about... Find a place... For us to try?
