Chapter 571

Chapter 571 is called "Execution Platform".

Summary
As Luffy and Garp face off against each other on the collapsing bridge, Garp reveals that he now consider both Luffy and Ace as his enemy due to their choice in piracy. However, Garp is then struck by memories of his grandsons', and Luffy evades his punch and retaliates with his own Gear Second punch, sending the Vice Admiral crashing onto the ground below, much to the shock of the other Vice Admirals. Luffy then lands on the scaffold, and prepares to use the key he received from Hancock to release Ace from his shackles. Sengoku then utilizes his Devil Fruit powers, transforming into a gigantic Buddha-like entity and decides to execute Ace himself, as well as killing Luffy at the same time. Kizaru shoots the key with a laser from below, breaking it, before Luffy can unlock the shackles. Suddenly, one of the unconscious executioners wakes up, revealed to be Mr. 3 in disguise. Luffy forms a Gomu Gomu no Gigant Fūsen, and Mr. 3 a Candle Wall, effectively blocking Sengoku's immense punch. However, the execution stand breaks and collapses. The Marines below then launch a barrage of cannon blasts at the three falling criminals, and Mr. 3 reveals that he was up there to avenge his fallen comrade, Mr. 2 Bon Kurei. He then forms a wax key and gives it to Luffy to free Ace. The blasts collide with them just as Ace turns into intangible flames to protect Luffy and Mr. 3.
