Long Summary
A marine rescue team enters the Human Auctioning House through the back door with the objective to secure the safety of the Celestial Dragons. Law throws the head that he previously severed back to the marines, shocking them as the head can still talk and feel its body. Law uses his powers and cut up numerous soldiers. Luffy goes into Gear Third. Kid uses his power to attract the marine's weapons to him. The force is so strong that even weapons inside the house flies to Kid, who uses it to build a massive metallic arm. The captains attacks the soldiers as their crews walk out.

The soldiers are commanded to attack the pirates without Devil Fruit abilities. Kid warns Luffy that the next time they meet, no mercy will be shown. Luffy replies that he will be the one who finds One Piece and laughs. Kid stares at him and Killer cut down the solider attempting to attack Kid. Kid tells Killer that they are going to an ocean whereby people who do not have the guts to say that they will find One Piece will die. Kid Pirates attacks the approaching soldiers. A soldier prepares to cut Law but is defeated by Bepo. The Rosy Life Riders arrives and are ready to set off. The Straw Hat Pirates defend themselves while running towards the riders in order to make their escape.

Law frees Saint Roswald's slave, Jean Bart, and invites him to join his crew. He accepts as long as that means bring free from the Celestial Dragons. The Straw Hat Pirates escapes on the flying fishes except Franky, who complains about the speed of Motobaro.

Kid gets shot by a beam and he angrily asks why his attacker is on the island. Heart Pirates make their escape and breaks the bridge behind them. On the sea, Motobaro is moving at a faster pace due to the modifications by Franky. They pass by Grove 8 and Duval says that it should be the place where Peterman's base is. The Heart Pirates come across the Kid Pirates. Law questions why a Shichibukai is there. Law emerges from the beam attack unscathed. Law comments that he does not want to encounter an admiral on top of all the people he has met, saying that he will make him let them pass, incorrectly identifying his attacker, a Pacifista, as Bartholomew Kuma.
