Nami's log pose begins to point to the sky, and the crew finds a map of an island named 'Skypiea' on a 200-year-old ship. They compete with the monkey-like Masira's salvage crew while they search for more clues on how to get there.

The Straw Hats decide to go to Jaya island to look for information on Skypeia. Meanwhile, Ace suddenly shows up on Buggy's ship; Buggy does not let any of his men attack Ace, fearing Whitebeard's retribution.

Jaya's main town is full of famous pirates that are constantly brawling with each other. Luffy and Zoro have a run-in with a pirate known as 'Bellamy the Hyena,' who ridicules their dreams and beats them up.

After refusing to fight Bellamy, Luffy, Zoro and Nami run into a certain cherry pie lover. They leave Mock Town, and get into a fight with Masira's brother Shoujou, another salvage monkey.

The Straw Hats meet with Mont Blanc Cricket on another part of Jaya; Cricket is a descendant of Montblanc Noland, an infamous "liar" who told of a gold city on Jaya, and Cricket was outcast for looking for artifacts of the gold city. He may be the only person who knows how to get to Skypiea.

Cricket explains how the Straw Hats can ride a dangerous vertical current called the Knock-Up Stream to get to Skypeia. However, they first have to catch a southbird to point them toward the point where the stream will erupt from the ocean.

While the Straw Hats are looking for a Southbird, Bellamy and his crew attack Cricket's house, and steal the gold artifacts he'd collected over the years from his salvage work. When the Straw Hats return and see what happened, Luffy decides to take a side trip back to Mock Town.

Luffy takes out Bellamy with a single punch. Meanwhile, the world government heads are concerned over Whitebeard, Shanks, and Luffy. The marines try to decide who will replace Crocodile as a Shichibukai - one of Blackbeard's crew shows up uninvited and nominates his captain.

The Going Merry is refitted by Masira and Shoujou to be more flight capable, and the Straw Hats catch a ride on the Knock-Up Stream for Skypeia.

The Straw Hats arrive in an ocean above the clouds. Usopp almost falls out of the Going Merry but is saved at the last minute. The crew is also attacked by a mysterious looking warrior, but is saved by the Knight of the Sky. Finally, they arrive at the border which transports them to the upper realm, Skypiea.

As the crew arrives in Skypiea, they are greeted by Conis and her pet Su. Both she and her father start explaining how the life in Skypiea is and how the different Dials work.

Nami finds out what should happen to anyone who enters the forest. Meanwhile, the rest of the gang are waiting for the wind to change but are rudely assaulted by Skypiea's police who are going to carry out Heaven's Judgement.

The Straw Hats have some problems with the local justice enforcer force called "The White Berets."

While trying to escape from Sky Island, Robin, Chopper, Nami and Zoro are held hostages by God Enel.

Conis leads Luffy, Usopp, and Sanji to a boat to get to Upper Yard, but she tells them it is a trap and almost gets hit by "Heaven's Judgment".

Luffy, Usopp and Sanji finally enter Upper Yard, only to find out that the whole road is trapped heavily, but at last they arrive at the Ordeal Gates. Meanwhile Robin, Zoro, and Nami go out to explore Upper Yard while Chopper stays behind to guard the ship.

Luffy, Sanji, and Usopp enter the Ordeal of Balls gate and encounter the Priest Satori.

Usopp, Sanji and Luffy fight Satori, but the power of Mantra seems to be too strong.

Chopper, threatened by priest Shura, blows the whistle for Gan Fall to come, but before he can arrive, Priest Shura assaults Chopper and begins destroying the Going Merry.

Gan Fall cannot handle Shura and lost the battle. Meanwhile, Satori is finally defeated by Luffy and Sanji.

Chopper is saved by a bunch of giant Southbirds, who tell him that Gan Fall was actually God. Nami, Zoro and Robin discover the reason why Upper Yard is a soil island: It was once part of Jaya, and this is the part that Liar Noland saw. Meanwhile the Shandia attack Upper Yard.

The Shandia attack on Upper Yard has started. The crew is finally reunited, and everyone speaks up about what has happened. Chopper takes care of Gan Fall, and the pirates plan to steal the gold on the island.

After befriending a wolf pack, Gan Fall tells the crew a little more about the history of Upper Yard.

Enel takes away the limitations of the priests. Also, Usopp witnesses a mysterious person fixing the ship; the next day Merry is found to be back to her original form. After getting her off the altar, the pirates plan out their course of action.

A giant python makes Luffy, Robin, Chopper and Zoro split while going to the ruins at the south.

Wyper takes out Shura and tells his goal to the Shandia, and Enel speaks up about how many people will be alive by the end of his plan.

Zoro fights the Shandia warrior Braham, and defeats him with Ittoryu (one sword style) 36 Pound Cannon technique.

Luffy fights Wyper, but after some time, he falls into some underground ruins. Meanwhile, Enel appears on the Going Merry and after telling that his true goal was the City of Gold, he takes out both Usopp and Sanji; then he vanishes and leaves Satori's brothers: Hotori and Kotori to avenge him.

Chopper is attacked by Gedatsu, who turns out to be a complete moron, and eventually defeats him, sending him plummeting to the Blue Sea. Conis and Pagaya help Aisa, and head to Upper Yard.

Enel defeats several members of the Shandia Tribe. Meanwhile, Gan Fall and Nami start and finish their fight with Kotori and Hotori. Hotori is defeated by Nami while Kotori is defeated by Gan Fall.
