Post-War Arc

The Post-War arc is the twenty-third story arc in the series, and the sixth in the Whitebeard War Saga of the One Piece series, continuing on from Marineford arc. The world reels from the death of Whitebeard, causing chaos to ripple all across the Grand Line. Luffy's mind and body are in critical condition, having not only endured breaking into and escaping from Impel Down and battling through the Marines at Marineford, but having all of his work come to naught due to Ace's death. Boa Hancock leads Luffy's allies to take him to Amazon Lily where he may recover from his drastic injuries. As the Marines cool down from their great battle, Sengoku learns that the World Government is taking strange courses of action...

An Era Ends, An Era Begins: Whitebeard's Protection Is Gone
All across the world, civilians rejoice that the Marines emerged victorious in the Battle of Marineford. The Eleven Supernovas, having all assimilated at Marineford to take part in the battle (viewing it from a safe distance), realize that Whitebeard has been killed, and all take their own separate actions. Eustass Kid claims that due to Whitebeard's death, the Yonkou's loss (consisting now of only Shanks, Kaidou, and Big Mom) has caused the balance of the Three Great Powers to crumble, and the world is about to enter an age like nothing ever seen before.

The world reacts in different manners to Whitebeard's death. Pirates celebrate that Whitebeard claimed that One Piece definitely exists. Civilians and Marines cheer that Whitebeard is dead. A band of ferocious pirates, under the helm of the self-proclaimed "Brownbeard", attacks the town of Foodvalten, which was formerly protected by Whitebeard. Even though the Marines were victorious, their victory has inevitably brought nothing but chaos.

Hancock, having traced Law's submarine through Salome, turns the Marines on her ship to stone and inquires on Luffy's condition. Law informs Hancock that Luffy's life is preserved for the moment, but that he is in critical condition. At that moment, the Impel Down prisoners, led by Ivankov, arrive in a stolen Marine ship. The Newkama Land citizens cheer that they will finally be able to head forth to the Kamabakka Kingdom now that the war is over and they are finally free. Ivankov informs Hancock on the trials he had to endure in escaping Impel Down, and how the death of Ace would crush anyone's mind. This prompts Hancock musing to herself, wishing that she could have instead been in Luffy's place, making at least two members of Law's crew note to themselves how nice it must be to have the Pirate Empress herself looking out for the Straw Hat's well-being. When Ivankov asks Law why he saved Luffy, he claims that he had no obligation, and Ivankov understands that he had done it without thinking.

Jinbei emerges from the sub, thanking Law for saving his life. Although Ivankov tells him to rest, he says that he can not, for his heart is in too much turmoil. He worries more for not Luffy's current condition, but rather what will happen when he awakens. Hancock demands that Bepo give her a Den Den Mushi; she claims that she can call the Kuja Pirates to carry them across the Calm Belt to Amazon Lily, where Luffy should be able to recover without possible discovery by the Marines.

At the destroyed Marineford, Sengoku is informed by Brandnew that Magellan had been beaten to an inch of his life. Upon reaching Level 6, Blackbeard had instructed the prisoners in each cage to engage in a battle for life and death, and the winners would be set free. Although Blackbeard only took four prisoners with him, there were many Level 6 prisoners that were missing, having escaped during the chaos. Although Sengoku demands that wanted posters of the escaped criminals be sent throughout the world, Brandnew claims that the World Government has chosen to hide the information of the Level 6 prisoners escaping, lest the world lose trust in the World Government, a decision which enrages Sengoku.

Elsewhere on Marineford, Donquixote Doflamingo and the Pacifista are beating Gecko Moria to death. Doflamingo claims that the government has decided that he is too weak to remain in the Shichibukai, and that it would be better if he was thought to be "killed in the war" rather than eliminated by the government. Moria asks if Sengoku is behind the decision, but Doflamingo claims that the decision was made by powers even higher than he.

Two weeks later, the after effects of the war are still taking hold. In the town of Las Camp in the West Blue, a new pirate crew has formed and its captain proclaims that they will head to the Grand Line. While the Marines are trying to stop them, new pirate crews are sprouting up all over the world.

With Ivankov and the Newkama having left on the stolen Marine ship to sail back to the Kamabaka Kingdom, Luffy, Hancock, Jimbei, and the Heart Pirates all return to Amazon Lily, with special permission given to the Heart Pirates to land on a small beach on the island, forbidden from going elsewhere. Luffy has woken up, and is now desperately trying to convince himself that Ace's death was but a dream. He goes on a rampage, with the Heart Pirates unable to calm him. Law comments that if Luffy doesn't calm down soon, his wounds will open up and certainly kill him.

At the central palace in Amazon Lily, Hancock is ecstatic to hear that Luffy is awake once more. She wishes to see him at once, though Elder Nyon prevents this as she sees such an action as a bad example to her subjects, and that allowing the Heart Pirates to even be on the island was a special exception already. Hancock's sisters, remembering that she hadn't eaten since she returned, tell her to eat, but only convince her to prepare a feast for Luffy so that he can recover. Nyon says that once Luffy is at full strength, she will permit him to see Hancock. To herself, Nyon thinks about both Hancock's strengthening "love sickness" and Luffy's incredible survival, going through both Impel Down and Marineford.

Back at the Heart Pirates' camp, the crewmembers discuss the women of the island and wish that they could go past their boundary to see them. Bepo, the ladies' bear that he is, wonders whether or not there are any female bears on the island, at which the other crewmembers are angered. Sitting on a rock not too far from them is Law who is looking at the Straw Hat he has in his hand with a curious look.

After recalling everything that had happened to him right before he fainted, and finally accepted that he is not dreaming, Luffy finally calms down. Jimbei watches over him, remembering that he promised Ace that if he died he would protect him. Luffy cries out to Jimbei, asking if him if Ace died, to which Jimbei confirms Luffy's belief, making Luffy cry even harder. Jimbei begins to tear at the sight of Luffy's remorse.

Birth of the Brothers' Bond: Luffy and Ace's Past
Ten years ago, on the road to Mt. Corbo on Dawn Island, Garp is bringing Luffy to be raised by Dadan, who has already raised Ace since his birth, ten years before the flashback. At the time Luffy, who had already met Shanks and obtained his Gomu Gomu no Mi, is angry at his grandfather since he has already made up his mind into becoming the Pirate King, much to Garp's dismay, as he wishes for Luffy (and Ace) to become a great marine. After knocking on Dadan's door in her large house in the forest, Dadan, a large, bandit woman, and two of her henchmen step out of the door. Dadan complains how much of a hassle Ace is, and that she can barely handle him. To her surprise, Garp tells her that he is entrusting her with Luffy. Claiming that she couldn't possibly raise both Luffy and Ace, Garp reminds her that he knows all about her illegal activities, and that if she refused, he would turn her and her men in. Angrily, she accepts. Suddenly, Luffy is attacked with a ball of spit. Turning to see who it came from, he sees Ace for the first time. Although Garp tells both Ace and Luffy to get along, the two stare at each other with seeming hatred.

And so Luffy was left with the bandits though quickly shows his disdain for them due to his previous encounter not too long ago. The bandits soon sit down to eat though Luffy complains about the small proportion he gotten while Ace has a bigger one. Dadan explains that since Ace slain the bufflo he get the bigger meat plus Luffy should count himself lucky that Ace is sharing with them. Dadan then tries to take advantage of Luffy and make him her servent. But her attempts backfire due to Luffy's simple-minded nature. Ace soon heads off on his own with Luffy following after, forgiving him for spitting on him earlier and trying to be his friend. But Ace ignores him and knocks down a tree to prevent Luffy from following him.

Luffy manages to break through however and continue after Ace on a rope bridge. Annoyed, Ace knocks him off and into the chasm below. Ace returns to the mountain bandits and claims he doesn't know where Luffy is when asked, which Dadan roughly shrugs off as not being her responsibilty. A week later, Luffy returns to the cabin battered but alive. When asked what happened, Luffy claims he was chased off a cliff by wolves. The next day Ace head off on his own again and Luffy tags along after him. And so it went Ace would venture out and Luffy would try to follow him, each time with Luffy ending up in one dangerous situation after another which Ace would purposely lead Luffy into.

After a unknown amount of time Luffy eventually managed to follow Ace out of the forest and into a junkyard area of the island known as "The Gray Terminal" where there is no law, no doctors and many homeless and dangerous individuals roam. Making his way through the junkyard, Luffy finds Ace with a boy his own age named Sabo. Ace shows Sabo some money he snagged off people at the front gate of the area when he came in and its revealed the two are collecting money for a pirate ship. Luffy overhears the two and tries to get the duo to let him join them. But they tie him to a tree and ,after pondering what to do with him, agree to just kill him! However Luffy yelling attracts attention to the three and the trio hide as pirates from the Bluejam Pirates arrive lead by a man named Porchemy. His subordinates reveal it was they whom Ace had stole the money from. At first it seem the three managed to hide before he spotted them, but Luffy somehow ended up near them and is captured. Porchemy threatens him but Luffy claims he doesn't know anything about the money, though his expression state otherwise and he accidentally gives away Ace's name. Porchemy then carries Luffy off stating he'll make him talk as Ace and Sabo look on in horror.

The Bluejams take Luffy back to their hideout, Luffy however yells he won't tell them anything. Porchemy tries to kill Luffy with a giant mallet but due to his Gum Gum Fruit, it just bounces off Luffy. Porchemy then switches to spike boxing gloves which indeed penetrate Luffy's defenses. Porchemy then has the others go search for Ace and Sabo as he tries to get Luffy to talk. Meanwhile said boys have started moving their hidden funds, scared that the Bluejams will come looking for it when Luffy breaks. As they do that, the Bluejams ask around the the junkland on any info on Ace and Sabo but no one gives them anything useful. Sunset comes and the two boys have managed to move their loot successfully. Sabo however, who went to see how Luffy was doing, rushes back and informs Ace that Luffy hadn't told the pirates where the money is. Not far from their location the leader of the pirates, Captain Bluejam himself, grows impatient when his money isn't found. Back with Porchemy and Luffy, the former savagely roughing up Luffy to get him to cough up the information. One of the pirate tries to get Prochemy to lay off as Luffy is being beaten to the point he can no longer say anything. Even those outside the building feel sympathy for Luffy but comment that no law official will come to that part of the island even with murder that happen now and then.

Despite all the abuse he taken, Luffy steadfastly refuses to rat out Ace. Porchemy, tired of getting nowhere, goes to kill him. Ace and Sabo suddenly bust into the hideout which the pirates instantly recognize they were the ones that took their money. Porchemy grabs Ace but Sabo saves him by knocking Porchemy down. He then grabs a knife, cuts Luffy free, and runs yelling at Ace to do so as well. However Ace decides to stay behind citing that when he faces a enemy he doesn't run. Sabo runs back to aid him and the two fight against Porchemy. In the end, the two come out victorious and Porchemy later faces the wraith of Captain Bluejam who kills him for his failure. Back in the forest, Sabo scolds Ace for his stubbornness and Ace scolds Luffy whose crying his eyes out after the encounter. Luffy thanks the two before Ace asks Luffy why he didn't talk when he was being tortured. Luffy responses he wouldn't have Ace as a friend anymore and that he doesn't have anyone on the island to rely on since he can't go back to Windmill Village and he doesn't trust bandits. Plus he doesn't wish to be alone. Ace, thinking back to when he was mocked by those that hated Gold Roger, realizes he in the same boat. As Luffy and he begin to bicker over pointless things, Sabo realizes that the Bluejams will come looking for them. Thus, he invites himself to live with Dadan much to her annoyance. Since then, Ace, Sabo and Luffy hang out together in the forest fighting any beast, bandit or pirate that got in their way. One day while they were out, Dadan picked up a newspaper and found out some shocking news, Tenryuubito were coming to the island for some unknown reason.
