Chapter 579

Chapter 579 is called "Seconds of Courage".

Summary
The marines notice Trafalgar Law and label him as Luffy's accomplice. Law is urging Buggy to get Luffy and Jinbei on board his submarine, Buggy questions who he is once more. The marines immediately begin attacking Law's ship, while orders are given on the ground to divide the Marine's forces to attack the Blackbeard Pirates and the Whitebeard Pirates, more marines begin emerging from trap doors that lead to underground passages. Blackbeard laughs and shakes up Marineford and the ocean around it, causing massive waves to flow around, with Jesus Burgess warning Blackbeard that they'll lose their footing if he continues on, while Blackbeard ignores it and threatens Garp and Sengoku that he's going to "close the book" on them like he did with Whitebeard.

Meanwhile in Sabaody Archipelago, an announcement is made to evacuate to the north side of the archipelago to avoid tsunamis. In the midst of the war, Coby is crying, Helmeppo asking him why he's sad. Coby simply answers that a "voice" in his head has disappeared. He notices how the marines are continuing to attack, even after completing their original goal of executing Ace. While he is thinking this, a nearby marine is injured, another marine goes to his side to help him only to be rejected by Akainu, saying they don't have time to treat the injured, much to the viewed shock of Tashigi and Smoker. Doberman commands the marines to beat every last pirate down, Akainu once more stating that they cannot allow the "evil known as pirates" to exist. Blackbeard is seen laughing some more, claiming that he'll destroy everything.

Elsewhere, while Buggy is flying in the air, he notices a gleam of light, as Kizaru shoots another laser beam in his direction. Fearing for his life, Buggy throws Jinbei and Luffy at the deck of Law's submarine. Bepo commands Jean Bart to grab them. Kizaru comments Law on escaping from him during the incident at Saobody Archipelago, and is about to attack him, until a shouting is heard. The shouting is revealed to be coming from Coby, who yells for everyone to stop fighting, since the marines have families waiting for them, and lives are being wasted. He yells at how the marines already accomplished their goal, how they are chasing pirates who don't wish to fight and are desiring war, and how they are abandoning injured marines while they could be treated, finishing his speech with how any marine that falls at this point is foolish. Akainu simply tells Coby that seconds have been wasted, and that the marines don't need someone like this, and gets ready to kill him.

Before Akainu could strike Coby, from out of nowhere, Shanks interferes, blocking Akainu's magma fist with his sword. He tells Coby that his few seconds of courage, which he was willing to throw away his life for, have changed the fate of the world. Law takes this opportunity to hurry up and escape, with Kizaru about to attack again, until he is stopped by Benn Beckman, threatening to shoot Kizaru if he "moves a muscle." Shanks picks up his straw hat that Luffy had dropped, and says that he has arrived to put an end to the war.
