In the beginning of the story, it is shown that the Germa Kingdom had managed to escape from Totto Land. Following this, VinsmokeJudge, Reiju and Ichiji are seen looking over a balcony, with Judge himself sighing. Unfortunately, Niji and Yonji had been captured by the Big Mom Pirates and were imprisoned in a book by Mont-d'Or's ability back on Cacao Island and put on display for the crew and citizenry to look at.
As they are restrained, the brothers recall how they were easily defeated by Big Mom herself. Suddenly, they are both punched in the face by Pudding for being so cruel to their brother, Sanji. She then leaves in a huff while Oven, who was wondering about Pudding's actions, carries the book with the brothers inside through a mirror with Brûlée using her powers. After passing through Mirro-World, Oven and Brûlée end up back on Whole Cake Island, with its fallen chateau in full view. Oven then drops off the book at a laboratory, where Kato, Brownie, Prim and Anana are prepared to dissect the brothers to learn about their modifications.
However, back at Chocolat Town, two silhouettes appear and scare away the townsfolk, except for Choco Police, though he is surprised by their presence. Brûlée, who was with a still recovering Cracker, learns of this and states to her brother that she believes that Vinsmoke Reiju and Ichiji have returned to rescue the other Vinsmokes while preparing to travel back there via mirror.
