To The Sea Someday! The Pledge of the Three Brats!

Luffy's attempt at using the Gum-Gum Pistol technique backfires. Luffy is no match for Ace and Sabo, and is defeated. The three invade Edge Town, a town located just past the Gray Terminal and fight off several bandits. When they go to High Town, the trio disguise themselves, but are discovered. Sabo is seen by a noble, who is tricked before escaping with the others. Back at the forest, Sabo explains to Ace and Luffy that he is the nobleman's son. Sabo explains that the reason he left: his parents made him study and take lessons on culture to marry a princess. Despite his father's objections, Sabo left for the Gray Terminal. Sabo explains that his dream is to live freely on the sea and vows that they will become pirates. Ace reveals that he will become a pirate to become infamous and Luffy reveals his dream of becoming the King of the Pirates. The three become brothers by sharing a drink of sake.
