One Piece: Adventure of Nebulandia

The Straw Hats embark on a dangerous trip to the sky where their destination comes straight out of a fairytale. The island of Skypiea and its grand city of gold await among the clouds, but a clash of winged clans and a man who calls himself God won’t make things easy! Only Luffy can resist this God’s mighty power and light the mysteries of the past.

20 years after his escape from Impel Down, the legendary pirate Shiki, the Golden Lion, reappears causing massive upheaval to the Marines. During his long seclusion, he was able to come up with a scheme to bring the World Government to his knees. On his way to execute the plan, Shiki crosses paths with the Straw Hat Pirates and becomes so impressed with Nami's knowledge of meteorology that he abducts her to forcedly enlist her into his crew. Luffy and the gang end up on a strange land populated with monstrous beasts as they desperately search for Shiki and Nami.

On a test-run of the Mini Merry, Usopp tells Brook the story of the Going Merry, a ship that served the crew well. However, to the Straw Hats, the Going Merry was not just a ship: It was a priceless, irreplaceable friend. *Scenes have been recreated with brand-new animation.

After Nami steals the Going Merry, Roronoa Zoro, Usopp, and later Monkey D. Luffy and Sanji (along with Johnny and Yosaku) set after her and wind up in Cocoyasi Village, Nami's hometown ruled by the tyrannical fishman Arlong. It is here that Nami's past and true motives come to light.

The words that Gold Roger, the King of the Pirates, uttered just before his death excited the masses and the world has entered a Great Pirate Era! There is a group of young pirates who are about to set sail on the Grand Line. Monkey D. Luffy, a rubber man. Roronoa Zoro aka “Pirate Hunter.” Usopp, a sniper. Sanji, a seafaring cook. And “Cat Burglar” Nami. They, the Straw Hats, all place a foot upon a barrel and make their vows before their next journey across the great ocean.

The special takes place during the two year before the Straw Hats reunite on Sabody. Luffy is currently in Rusukaina training to get stronger to take on the New World. However the training is interrupted when Hancock's sisters, Marigold and Sandersonia, are kidnapped by the Byrnndi World, a pirate who was locked away on Level 6 of Impel Down but escaped during Luffy's invasion to save Ace, in order to lure Hancock to him and use her as a hostage against the World Government due to her Shichibukai status. Thus Luffy and Hancock head off to confront him and save Hancock's sisters.

When Nami falls ill, the Straw Hats seek medical care for her on Drum Island. There they meet reindeer doctor Tony Tony Chopper and the Wapol Pirates.

A girl named Olga is pursued by both the World Government and a man named Mad Treasure, as she is the only one who knows the location of the Pure Gold, a substance that can buy the entire world. Olga ends up sailing with the Straw Hat Pirates, and they journey to find the Pure Gold on the lost island of Alchemi, which is located inside the stomach of a large angler fish named Bonbori.

As the Straw Hat Pirates sail through the Grand Line, a sudden eruption of geysers beneath the Going Merry sends the crew flying over a nearby island. In the chaos, Chopper falls overboard and becomes separated from his friends. While Luffy and the others land on the far side of the island, Chopper finds himself hailed as the new king by the local animals. However, danger looms as a group of human “horn hunters” arrives. Their leader, Count Butler, is a violin-playing man who consumes horns to gain strength, and he seeks to devour the island’s greatest treasure to inherit immense power. Can Luffy and the crew stop Count Butler’s scheme and save the island? And will they be able to show Momambi that not all pirates are the villains he believes them to be?

The Straw Hats visit a recreational island, run by Baron Omatsuri, who asks them to complete a series of ordeals if they wish to stay on the island. Luffy accepts and the Straw Hats work together to complete them, but as the island's mysteries unfold, their lives and friendships are put to the test. It's up to Luffy to stop the Baron's plot and keep his crew together.

From a brotherhood bound by three cups of sake, one brother’s story has yet to be told!

Now, they’ll fight in disguise for the Colosseum’s ultimate prize: Ace’s Flame-Flame Fruit.

Isaac Netero is the chairman of the Hunter Association. Decades ago he sealed away Jed, a Hunter who had mastered the use of On, the dark "shadow" of Nen. Now On users have reappeared at the Heaven's Arena "Battle Olympia" tournament. For Netero, this is the last mission: to protect the Association and the world from a threat driven by hatred and the thirst for revenge. And he's going to need all the help he can get in order to succeed.

All Might and Deku accept an invitation to go abroad to a floating and mobile manmade city, called 'I-Island', where they research quirks as well as hero supplemental items at the special 'I-Expo' convention that is currently being held on the island. During that time, suddenly, despite an iron wall of security surrounding the island, the system is breached by a villain, and the only ones able to stop him are the students of Class 1-A.

One day, Kurapika spots a child who looks very similar to his childhood friend, Pyro. However, when he catches up to him, the boy steals Kurapika's eyes with some kind of magical power. Gon, Leorio, and Killua promise to help find who took his eyes and get them back, but Killua is having his own problems when he is forced to face his past and whether he really is worthy to have Gon as a friend.

Class 1-A visits Nabu Island where they finally get to do some real hero work. The place is so peaceful that it's more like a vacation... until they're attacked by a villain with an unfathomable Quirk! His power is eerily familiar, and it looks like Shigaraki had a hand in the plan. But with All Might retired and citizens' lives on the line, there's no time for questions. Deku and his friends are the next generation of heroes, and they're the island's only hope.
