One Pace
The path the to the New World takes the Straw Hats thousands of leagues under the sea to the underwater Fishman Island. However, the island's dark past is reaching a breaking point, and Luffy and his crew are caught in the middle of the conflict.
Encased in a protective bubble, the Sunny departs for Fishman Island far under the sea. As the Straw Hats marvel at the sights, Franky tells the crew about their greatest ally in their time apart. But suddenly, a mysterious shadow closes in on the ship.
Luffy, Zoro, and Sanji leave the relative safety of the Sunny to face the Kraken in its own territory. Putting their powerful new skills to work, they survive the encounter but are swept away by a downward current and become lost in the murky depths.
After a near miss with a creepy undersea ship and Fishman Island in sight, Luffy’s crew is halted by a group of fishmen riding atop sea kings. But time is of the essence, so the Straw Hats attempt a desperate maneuver.
The mermaids of Fishman Island give the Straw Hats a warm welcome, but Sanji is struck with a sudden medical emergency! Luffy and co. take their anemic friend to the Mermaid Cafe to rest, where they are introduced to its soothsaying owner.
The pirates receive an unexpected invitation to Ryugu Palace from Neptune himself, king of Fishman Island. Tempted by the smell of food, Luffy wanders the palace and soon finds an enormous tower with a sturdy yet battle-worn door.
Plagued by the unwanted advances of a lunatic fishman with a dangerous power, Mermaid Princess Shirahoshi has been hidden away in a lonely tower for years. Meanwhile in the palace, things take a sour turn for the Straw Hats.
Ryugu Palace falls into chaos. While Luffy escapes with Shirahoshi, the pirates who infiltrated its walls attack with a strange desperation. After a scuffle of their own, Sanji and Chopper come across an old friend with troubling injuries.
Hody’s plan for revenge is set in motion, and the Straw Hats who have unwittingly taken control of the palace must now defend it against the New Fishman Pirates. Outside, Luffy’s excursion with Shirahoshi is rudely interrupted.
Jinbe reunites with Luffy in the undersea forest and reveals a shocking connection to an old foe. The former Warlord begins a tale of when two famous figures fought to undo the animosity that existed between humans and fishmen.
Queen Otohime tried to lead the Ryugu Kingdom into an era of coexistence between humans and fishmen. At the same time, the heroic Fisher Tiger battled humans to free their slaves from captivity.
Fisher Tiger’s past quickly caught up to him, and he left his crew with a sobering, final command. While Jinbe vowed to uphold Tiger’s and Otohime’s ideals, Arlong’s resentment only grew, and soon, the Sun Pirates faced a crisis of identity.
The sudden appearance of a Celestial Dragon almost imperiled Fishman Island, but Queen Otohime’s ability to end hostilities provided a ray of hope for everyone. Just when the path to the future seemed bright, a shot echoed through the plaza.
After completing his tale, Jinbe begs Nami for forgiveness. Soon after, Hody broadcasts across all of Fishman Island, and all watch in horror as he conducts his hostile takeover. Luffy is ready to fight, but Jinbe has something else in mind.
Hody experiences a strange side effect of the energy steroids, and his body undergoes a horrifying transformation! The three princes of the Ryugu Kingdom rush to the scene, but Hody's crewmates have a dirty trick up their sleeves.
Shirahoshi and Jinbe hurry to free King Neptune but run headlong into a trap. There, Hody reveals a shocking truth about the history of his revolution, but even in the face of Hody’s cruelty, Shirahoshi holds true to her mother’s dying wish.
The Straw Hats have reassembled at last, an army of New Fishman Pirates standing before them. With the last two years still fresh in their minds, the Straw Hats’ training is put to the test, and they unleash a flurry of new techniques.
Franky’s mechanical masterpieces have transformations in store that can only be described as "super!" However, onlookers curb their enthusiasm when a foreboding shadow is cast upon the plaza by a giant ship hurtling toward the island!
Shirahoshi flees into the open sea, hoping to draw the Noah away from Fishman Island. Luffy follows her, but he must contend with Hody Jones along the way. Luckily, the appearance of a new ally gives Luffy a chance to protect Shirahoshi.
The Straw Hats hold their own against the powerful officers from Hody’s crew. But their struggle will be in vain if Luffy cannot stop the Noah. Meanwhile, Hody becomes stronger than ever.
Neptune’s army aids the Straw Hats against the New Fishman Pirates, finally accepting the crew as allies. As the fight continues, Fukaboshi’s transponder snail reveals the bone chilling truth behind Hody's motivations.
