Short Summary
The reunited Vinsmoke Family have breakfast in their castle. As they discuss their political affairs, Sanji and Vinsmoke Niji engage in a confrontation which ends with Niji attacking the head chef, Cosette, and with Sanji once again denouncing his family's pride and values. Vinsmoke Judge proceeds to threaten Zeff to pressure Sanji into cooperating with the upcoming wedding, leading Sanji to recall periods of his time at the Baratie.

Later, Sanji discovers a bloodied and beaten Cosette in the castle. Vinsmoke Yonji appears and goads Sanji into confronting Niji again. Yonji then leads him to a sequestered area of the castle, where Sanji is shocked to discover clones of Germa 66 soldiers being monitored inside liquid capsules.

Long Summary
As the Vinsmoke Family eats breakfast, Judge reflects that Broc Coli Island was likely affected by the fall of Doflamingo's weapon trade, and he and Reiju note that one side caved in by hiring Germa 66 to end the war rather than continue creating casualties. However, Ichiji and Niji do not care about the politics of the war and are only concerned with the money they made. Yonji mentions the possibility of working for both sides, but Judge says that it would make them no better than pirates. Niji says that the Reverie is coming up soon, and Judge replies that if their goal nears completion, they will likely be stripped of their right to participate in Reverie. Niji remarks that it is strange to see his father in high spirits, expressing surprise that Sanji is still of use to them. He tells Sanji that when he left the family 11 years ago, they thought about humorous ways he might die, causing Yonji to laugh hysterically.

Sanji then tells Niji to finish the food left on his plate, but Niji replies that he does not want it anymore and will throw it away. Sanji's expression darkens as he orders Niji to eat it, calling him a spoiled prince who does not know the value of food. This enrages Niji, who calls for the head chef Cosette, as Sanji had ruined the food she made. Cosette appears and vehemently apologizes for making food not to Niji's liking, and Niji tells her to stay still as he throws his plate at her. Sanji appears in front of Cosette and catches the plate, causing the food to fall onto the floor. Both Niji and Sanji are angered, with the latter being furious over his brother attempting to harm a woman. Niji says that she is just a menial servant, and Sanji picks up the food, examining it and complimenting its nutritional value. Cosette attempts to stop him so she can clean it up herself, but Sanji remarks that a lot of effort must have been made to make this dish as he eats it, horrifying Cosette. Niji is repulsed by Sanji's action, and Sanji tells Cosette that she used the perfect seasoning for this dish, causing her to become flustered and excited.

An enraged Niji attempts to kick Sanji, but Judge tells him to not attack him before the wedding, causing Niji to halt his kick right in front of Sanji, though the force of it is enough to knock Cosette over. Niji calls him a shame to their family, but Sanji replies that being in this family is shameful to him, saying that them not appreciating meals, harming women, and treating their subordinates like expendable pawns goes against everything he stands for. However, Ichiji replies that Sanji is acting like a commoner and says that they are meant to act like royals. Judge concurs with Ichiji and Niji and holds up a picture of Zeff, wondering if he had a negative impact on Sanji's upbringing. Sanji is shocked that his father knows Zeff, and Judge states that they have pinpointed the chef's location. Judge notes that Sanji is growing pale as he remembers gaining the exploding wristlets from Tamago, and tells his son that if he continues challenging and defying him, he will ensure that Zeff will be killed. This shocks Sanji, and Judge gives him a single warning to not cause any trouble and leave his old life behind, which will allow everyone to get through the wedding unscathed. Sanji remembers being raised by Zeff on Baratie and their tearful goodbye, and Judge tells him to make himself presentable for their lunch meeting with Big Mom and Purin later today.

Later, Sanji holds a heavily beaten and unconscious Cosette, becoming enraged at Niji for his vindictive actions. However, Yonji appears around the corner and says that Sanji brought this on himself for sticking up for peasants. Yonji asks if Sanji wants to see Niji, and Sanji accepts his offer, but they end up going to a highly secure room, which they had tried a lot to get into as kids. They enter the room, and Sanji gapes in awe as he sees dozens of clones being kept in large bottles.
