The Minister of the Left gives Nami a new Log Pose with three needles so they can get to the islands in the New World. He explains that the new log pose takes in the magnetic waves of 3 surrounding islands and that the needle that moves the most is the direction of the most dangerous island. After hearing that, Nami, Chopper, and Usopp tell the Minister of the left to keep it down so Luffy doesn't hear, which he evidently does. He then grabs onto Nami wanting to see the new Log Pose and says to go in the direction of the needle that moves the most, stating, "that's where the party is". Nami insists that she will tell the crew where to go. However, Luffy states that he should decide where they should go, as he is the captain. Franky gets a new haircut and they start to leave but Shirahoshi comes and ask them to pinky promise to come back and they did. The Straw Hats and the fishmen go their separate ways and Luffy remembers the times when Shanks, Rayleigh, Jimbei, and Ace told him something important. The Straw Hats then comment about what they will do once they are in the New World. 
574 "To the New World! Heading for the Ultimate Sea!"
"Shin Sekai e! Saikyō no Umi o Mezashite" (新世界へ! 最強の海をめざして) 
November 25, 2012
The Straw Hats are heading to the New World. Nami is taking a bath in the Thousand Sunny and Chopper comes in. Nami asks Chopper if he wants to join her in the bath and he says no claiming that he took one two days ago and the cloud reminds him of cotton candy. Sanji and Brook walk by and saw Nami taking a bath so they stare at her. Nami asked Chopper to move aside away from the cloud she made and the cloud electrified Sanji and Brook. Chopper claims he is scared and he won't eat the cloud. Meanwhile Luffy, Zoro, Usopp, Franky and Robin are hanging out. Luffy tells Usopp to hurry up with the fish hook because he wants to catch and eat a big fish. Robin says that Luffy and Usopp are having fun. Franky says he wants Cola with a big fish. Zoro says he wants to have a drink to celebrate entering the New World. Luffy, Zoro, and Usopp sees three big fish. Zoro wants to eat a fried fish with salt. Usopp wants a fish sliced up and grilled. Luffy wants a fish with mayonnaise. Usopp says which fish Luffy wants and claims that it is not edible. Luffy punches the fish with gear second and Usopp uses the fish hook to grab hold of it. The fish that they caught suddenly got ate by a bigger fish and Zoro uses 360 pound cannon killing it. Nami is still in the bath and she claims that the rest of the crew are making too much of a ruckus and they she shouldn't have trusted them in watching the ship for her. They suddenly got caught in a White Storm and Luffy claims it is the wormhole of his dreams and Usopp slaps him for saying that. Nami claims the crew to be stupid for getting into too much trouble while she was taking a bath. They get caught in the White Storm and they try to hang out to something so they won't fly out of the ship. They finally crash into a whale without noticing at first. Brook then claims that the whale is Laboon but they finally see a whole bunch of whales and the others claim that Laboon is not here but in the first half of the grand line. Sanji then says that they need to get out of there and asks Nami about what they should do. Nami says they don't need to do anything and Sanji listened. The Straw Hats asked one of the whales to give them a ride to the surface of the New World. Brook sang a song for the whales so they can bring them to the surface. Before they got to the surface the Straw Hats remembered the times during their training to become stronger so they can regroup and head towards the New World. They finally surfaced and Thousand Sunny hopped off the whales and landed onto the ocean. The Straw Hats say goodbye to the whales and they see some ships claiming they are pirate ships but then they saw that the ships belong to the Marines.

There is a whole fleet of Neo Marine ships, one of which houses Ain and Bins. The Straw Hats fight back against a fleet of Marine ships, but it turns out to be a mirage. Huge raindrops appear out of nowhere, and the water suddenly splits. The Straw Hats wake up with different clothes. However, Sanji sees that the food he cooked is gone, so he blames it on Luffy, Usopp, and Chopper until Chopper wonders if the sea is haunted. Suddenly, the food begins to be eaten very quickly. Luffy finds the person who ate the food and it turns out to be a little girl. She attacks the Straw Hats and they fight back. It is then revealed that she ate the Mini Mini no Mi and that her name is Lily. She turns out to be a giant, though her devil fruit makes her small. She befriends the Straw Hats after they save her from drowning and wants to see her dad (this is why she invaded the Marine's fleet of ships). She then talks about food to Luffy. On the Neo Marines' ship, Ain calls Shuzo and asks why he was not there. Shuzo tells Ain that he will make a better second-in-command and that he is going after Lily's father. The Straw Hats see Marine ships coming their way who have Lily's father captive. They are heading towards Impel Down, so Luffy declares battle against the Marines.

Zoro uses his 360 pound cannon and sends Momonga back that destroys a Marine ship. From the sidelines, Nami notices the wave changes in the ocean and realizes a Thrust-up Stream is coming. When Usopp asks what that is and asks if it's similar to the Knock-up Stream like the one that took them to Sky Island, Nami says it is, but smaller, but still has enough power to destroy a Marine ship. She has Franky fire the anchors to the raft Panz Fry and the others are on and lets Sanji and Lily know in advance. Luffy has a hard time against Shuzo's fighting style due to his long arms, but then starts using Haki to overwhelm Shuzo again.

As Nami has everyone get on the ship she has Franky use a Coup de Burst after the raft everyone is one get close to the thrust and they fly away. However, Luffy and Zoro fall off due to the raft breaking and Luffy uses his arms to grab the raft while Shuzo uses a knife with a Vivre Card attached to it on the raft. After they get away, Momonga gathers his men on a broken ship and laments them having gotten away again while Shuzo goes to finish the Marines off with an attack and defeats Momonga. He then travels to the Straw Hats location and recalls his past fight with Ain and how their fight lasted for over five hours till she won, prompting their leader Z to give her the win and the title of next in command. Shuzo is determined to become the new next in command and destroy the pirates. The Straw Hats land in a location around some rocks and Robin notes they will be safe for now and Nami happy that the planned worked and that they finally got out of the sea. Chopper works on Panz Fry noting he had some bad injuries and that he'll be fine if he rests. Lily thanks Chopper for helping her father and the rest of the crew. Luffy is excited that he can try Panz Fry's cooking and Lily reveals she took some food from the Marines and while Zoro notes that's odd given the circumstances, he changes his tone after seeing she took some sake also. As Luffy asks Panz Fry to make some food, Sanji kicks him stating he needs to rest and Chopper says Luffy didn't listen. However, Panz Fry says he will cook for then despite Lily's protest stating that as a chef and Giant, he was saved by the crew and would shame himself if he didn't repay them for risking their lives and thanks Luffy for saving him and will cook the food.
