Dressrosa Arc

The Dressrosa Arc is the twenty-seventh story arc in the series and the second in the Pirate Alliance Saga of One Piece, continuing from the Punk Hazard Arc.

The Straw Hats, Trafalgar Law, and Kin'emon, having formed an alliance, travel to Dressrosa as part of their plan.

Summary
As the news of Doflamingo's resigning and the pirate alliances spreads, chaos ensues. In war zones, armies are desperate to get in contact with the Shichibukai in order to get new supplies of weapons, while pirates everywhere start panicking about the alliances as reported by Absa. Meanwhile, Doflamingo receives the promised call from Law, with some of the Straw Hats on the other end seemingly surprised that the Shichibukai actually picked it up. Luffy returns Doflamingo's greeting by shouting his declaration to be Pirate King, followed by angrily threatening the king that he is willing to return Caesar, but if he finds they were repeating the same actions as they did on Punk Hazard, he was going to beat the Shichibukai up. Doflamingo simply chuckles, and asks where Luffy has been (with the young pirate stating it was a secret) and then states that he wanted to meet the Straw Hat, claiming that he has something that Luffy would do anything to get. As Luffy starts envisioning meat Usopp drags his Captain away from the Den Den Mushi, with Law picking up the receiver to start negotiations. After Doflamingo made sure that Caesar was all right, Law tells his old boss the time and place of the pick up. Luffy then abruptly hangs up on the Shichibukai before he got caught up in Doflamingo's pace again.

Sanji then starts asking if it wouldn't have been better for them to limit the forces present for the pick up, but Law refutes this, stating that their real goal was to find the hidden SMILE factory and destroy it. Luffy starts getting excited about this latest adventure, and then his next in which he plans on going to the Wano Country. However for now, they decided to have breakfast, during which Kin'emon briefly explains the events leading to him and Momonosuke ending up on Punk Hazard.

When Law hears that the samurai's were heading to Zou, he states that he was also planning on heading there after destroying the factory to join his crew. When Kin'emon finished telling his tale, Franky, Chopper and Luffy then get carried away, saying that they will help the samurai's friend, Kanjuro as well, much to Law's annoyance. At the new Marines HQ, a debriefing was taking place, held by Commodore Brannew, about Doflamingo's abdication and Law's alliance, while mentioning the new Shichibukai, Buggy. In response to this, Fleet Admiral Sakazuki states he sent Fujitora to investigate.

At Dressrosa, Baby 5 goes looking for Trebol, who suddenly appears in front of her. Baby 5 then tells him that Doflamingo is looking for him, and to bring 'that' with him. After Trebol teases her about her captain's constant execution of all her previous boyfriends, he then goes to meet the former Shichibukai. While there, it is then revealed that the object requested by Doflamingo was infact the Mera Mera no Mi, Ace's Devil Fruit prior to his death which is then entrusted by Doflamingo to another of his surbodinates Diamante, while commenting that Luffy will come running to him because he wouldn't want anyone else to have it.

Elsewhere, the Straw Hats soon sight Dressrosa.
