Whole Cake Island Arc

The Whole Cake Island Arc is the twenty-ninth story arc in the series and the first in the Yonko Saga of One Piece, continuing from the Zou Arc and the Pirate Alliance Saga.

Monkey D. Luffy, accompanied by Nami, Tony Tony Chopper, Brook, and the minks Pedro and Carrot, heads to Whole Cake Island, the home of Big Mom of the Yonko, in order to rescue his crewmate Sanji from an arranged marriage between the Charlotte Family and the Vinsmoke Family.

The World Abuzz: Kings and Emperors on the Move
Nefeltari Vivi and Cobra set out to sea with their guards and staff, and Vivi climbed all around the ship as she embraced the life she had left behind two years ago, which scared Igaram. Cobra was in ailing health and it was questioned whether he should even make the voyage, but he was intent on doing so, determined to ask the World Government about the poneglyphs when they reached their destination: Reverie.

Other rulers across the world prepared to head to Reverie as well. Stelly, the new king of Goa Kingdom, and his wife Sarie Nantokanette stayed in an inn in Loguetown on their way. The ruler of Kano Country lamented that the Chinjao Family was unavailable to accompany him to Reverie, and Wapol headed there simply to take Dalton down. On Drum Island, Dalton prepared to go as well, with Kureha accompanying him as his doctor. The Riku Family and Mansherry prepared to head to Reverie, with Rebecca and Elizabello II accompanying them. On Fishman Island, Neptune and his sons begged a frightened Shirahoshi to accompany them, as they were prepared to present Queen Otohime's treaty to Reverie.

Somewhere at sea, the members of the Sanji retrieval team could barely do their sailing work as they were still recovering from the jump off Zou. Suddenly, Carrot appeared in front of them, amazed by the big world around her. The Sanji retrieval team was less than enthusiastic about her, but she begged them to let her stay, and they relented. Right then, Pedro received a newspaper revealing that the headquarters of the Revolutionary Army on Baltigo had been discovered in a state of ruin.

Luffy was shocked to hear the news, though had not previously realized that the revolutionary leader Monkey D. Dragon was his father until his crew told him. They read that the base had been destroyed by Blackbeard, who fled after briefly clashing with Cipher Pol. However, Pedro noted that if Dragon or Sabo were killed it would have certainly been reported, which calmed Luffy. Suddenly, the Thousand Sunny caught on fire due to Luffy leaving the stove on, and the crew struggled to navigate a fierce storm.

At Zou, Wanda talked to Bariete about Carrot's departure before telling Inuarashi that he should rest, but the ruler was preoccupied with wondering how Jack and his men got to Zou twice. Meanwhile, Jack sunk along with the wreckage of his ship, waiting for someone to rescue him. Meanwhile, Kaido received the report of Jack's defeat and became very emotional. Drinking heavily, Kaido lamented the loss of SMILE preventing him from creating a crew of all Devil Fruit users. His subordinates stated that they should not take Luffy and Law's alliance lightly, but Kaido blew them away in anger, saying that they were nowhere near his level and that they were only playing little pirates' games, pointing to the defeated Eustass Kid in a cell nearby.

At the Thousand Sunny, calm returned as the crew sailed through a snowstorm. Luffy presented them with his "random curry," although it was made very poorly, and the crew was outraged when they saw that he used their entire rations to make it.

A few days later, the Big Mom Pirates' ship sailed to the #28 Tarte in an area with cotton candy snow. On the ship, Sanji and Tamago argued over Sanji's unwillingness to fully cooperate with the Big Mom Pirates and the Germa 66, and Vito brought out a picture of Charlotte Purin, which Sanji was immediately enamored with.
