After they leave, Absalom rallies the zombies together for the Night Attack, while the ghosts from before return to their master, a Gothic Lolita-style Ghost Princess Perona. Gecko Moria himself, a massive, giant-like man, is awoken. The Straw Hats come to the realization that Thriller Bark is not an island, but rather, a massive ship!

After awakening the General Zombies, Absalom is accosted by Lola, a zombie warhog obsessed with making him her husband. After learning that he's chosen Nami to be his bride, Lola sets her sights on the navigator. Nami, Usopp, and Chopper manage to escape their coffin and find themselves in a garden, surrounded by animal zombies, including a bizarre penguin-bulldog zombie named Inuppe who talks and acts a lot like Sanji. The other Straw Hats, meanwhile, discover a hallway lined with suits of armor, and realize that Zoro is now missing as well.

With their goals in mind, Luffy, Sanji, Robin, Usopp, and Chopper go after Nami and Moria! Meanwhile, Franky and Zoro head toward Brook. However, Hildon tells the others of the Straw Hat's plan.

Having deduced that Perona used her Horo-Horo powers to project her spirit, Usopp attempts to fire an attack at it. But the attack appeared to miss with Perona producing a Special Hollow bomb to hold Usopp while she returned to her body. Usopp luckily uses an Impact Dial to absorb the explosive force, using it to take out the Wild Zombie Hippo Gentleman with some injury as consequence. Usopp then reveals that he actually fired an adhesive on Perona's body, beating her by scaring the trapped girl to death with toy cockroaches and an inflatable ten-ton hammer. As Chopper begins to notice Jigoro and Inuppe acting less like Zoro and Sanji, Oars undergoes the same transition and makes his way back to Gecko Moriah. Meanwhile, Zoro and Ryuma's fight is getting intense as Brook tells Franky that Ryuma is actually fighting for real.

As Abalsom makes another attempt to finalize his marriage to Nami, the other Straw Hats are fretting over Oars hunting them all down. Oars assumes he is kill the Straw Hats and attacks Sanji upon identifying him from his badly drawn wanted poster. While Oars lacks any Devil Fruit power, he is able to use Luffy's attacks to smack Sanji into a building. Oars was about to crush Sanji when Usopp used his Fire Star to set the zombie's head on fire, only to provoke him as Zoro and Franky attempt to fight him. But Oars is too fast and overpowers everyone before destroying bridge where Usopp, Chopper, and Robin were standing. As a wounded Usopp cursed "Luffy" while lying on the ground below alongside his teammates, Oars stood over the seemingly defeated Straw Hats while proclaiming that he is a servant of Moriah. Elsewhere, Luffy's continued pursuit of Moria leads him out of the manor and into the forest.

With Moriah's guidance, Oars is better able to counter the Straw Hats' strategies and turn their attacks against them. Franky is knocked unconscious after a failed attempt to fire himself at Oars with a giant slingshot known as Kuwagata and shoot him at point-blank range with Weapons Left. Nami arrives and joins the battle, but Oars demonstrates that he can somehow stretch his limbs, which the crew realizes is Moriah's Devil Fruit powers. Elsewhere, Luffy meets up with the Rolling pirates and their captain Lola the Proposer, whose shadows have been stolen by Moria. Lola has her crew plant all the shadows they captured into him in order to multiply his fighting strength and grant him new skills so that he can defeat Moria. The result is a monstrous version of Luffy, called Nightmare Luffy, that proceeds to reach his crew and take out Moria before the shadows leave his body after ten minutes' time.

Despite nearly being vaporized, Luffy, Zoro, Sanji, Robin, and the Rolling regain their shadows at the last second along with the rest of Moriah's victims. As Hogback informs Absalom of their leader's defeat, the Straw Hats surround the still unconscious Luffy with Usopp worries that Luffy might hurt himself from facing stronger enemies in the future. As the Rolling Pirates offer to lead Nami to Moriah's treasure, she remembers Kuma before seeing him on the collapsed tower. Contacting his superiors via Transponder Snail, Kuma receives orders from the World Government to kill the Straw Hats and everyone else on Thriller Bark to prevent Moriah's defeat from becoming public. After taking out some of the Rolling Pirates with a strange move that sends several people flying backwards, Kuma turns his attention to Zoro.

Brook tells Luffy that he is glad to be alive and asks if he can join the crew, which Luffy approves of. All the Straw Hats are shocked by this, except for Zoro, who is sleeping, and Robin, who knew Luffy would accept him no matter what, but they nevertheless welcome him to the crew. Two days later, Usopp and Franky make a grave for the dead Rumbar Pirates, and Zoro lays the broken Yubashiri at the grave. Nami gets a Vivre Card from Lola, which points the way to Lola's mother, a pirate in the New World. Luffy takes out the piece of paper he received from Ace, which is also a Vivre Card, and learns that as it is burning and shrinking, Ace's life is in danger. Believing that Ace can get out of trouble on his own, Luffy decides to head onward rather than go to rescue him, and the Straw Hats sail away from Thriller Bark. As the Luffy and his crew sail away, three enormous and mysterious figure appears in the fog, looking over Thriller Bark.

The world rejoices in the wake of Whitebeard’s death, and a host of powerful pirates vie for his position. Meanwhile, Luffy’s friends fear that Ace’s death may be more than the rubber-man can handle – if he ever wakes up!
