Short Summary
After Luffy punches Charloss, the guards begin to attack the Straw Hats, and most of the observers, except for Charloss' family, Kid and Law's crews, evacuate. The Straw Hats fight the guards as Robin, Brook and Usopp arrive to help, with Usopp accidentally knocking Roswald unconscious, as he falls through the roof, and works to save Keimi. The Marines are alerted to Luffy attacking Charloss, and surround the Auction House. An infuriated Shalulia attempts to kill Keimi, but is knocked out by a sudden burst of Haki from Rayleigh, who emerges from backstage and reveals himself to Luffy.
