The kids on Fishman Island are wearing the "hero's hat" they asked for in Chapter 653.

Short Summary
Purin learns that the group she was talking to is from the Straw Hat Pirates while the Sanji retrieval team also learns that Purin is Sanji's betrothed. After explaining more about the Charlotte Family and her thoughts about Sanji, Purin shows the team a route to Whole Cake Island that will allow them to arrive undetected.

The Sanji retrieval team later returns to the Thousand Sunny but is unable to find Pekoms. They soon find a message telling them to turn back.

On another island, Sanji's two older brothers end a two-year war.

Long Summary
Luffy and the Sanji retrieval team are shocked to discover that Purin is not only one of Big Mom's daughters, but the daughter that has been engaged to marry Sanji. Purin, in turn, is equally shocked that the guests she had invited for tea were Sanji's crewmates. She asks them how they managed to get past Totland's tarte inspection, before warning them that they will be killed if Big Mom discovers their presence. However, she remembers that the Straw Hats are also famed pirates, and retrieves a knife to defend herself; Pedro in turn threatens Purin until Nami diffuses the situation.

The group discuss the situation over tea. Purin reveals that the Charlotte Family is compromised of 129 people (Big Mom, her 43 husbands, 39 daughters and 46 sons), and that Big Mom's children have all been raised to understand that their future marriages will always be arranged to grow the strength of her crew. However, one of Purin's beloved sisters left Whole Cake Island to pursue a marriage for love, which attracts Nami's attention.

Chopper proceeds to ask Purin if she had met Sanji yet. Purin is flustered by the question and blushes, responding that she had met him once. She remarks on his gentlemanly mannerisms, his reputed strength, and their shared passion for cooking; however, Chopper has to correct her misconception that Sanji's epithet, "Black Leg", did not actually mean that his legs were black. Luffy responds enthusiastically to Purin's admiration, but when Nami asks if Purin has fallen in love with Sanji, she becomes even more flustered and responds that it didn't matter because Big Mom's commands are mandatory.

When Pedro suggests binding and gagging Purin to prevent her from revealing their presence in Totland, Purin draws a map for the Sanji retrieval team, revealing a secret route through Totland that will allow them to arrive onto Whole Cake Island undetected. She reflects that, despite everyone's excitement at the upcoming wedding, and despite her own happiness at finding Sanji so 'wonderful' and compatible, she did not want to stand in the way of his intention to return to the crew. The crew express great shock at the fact that Sanji turned down a woman - Luffy is so moved that he even cries - but Purin replies that seeing the crew's mutual commitment to Sanji helped her to decide that she did not want to marry someone who would spend the rest of his life regretting the marriage. She arranges to bring Sanji to rendezvous with the retrieval team on the southwestern coast of Whole Cake Island, but warns them that Big Mom will never willingly let Sanji go.

When someone comes knocking on the door, Purin helps the team sneak out. After purchasing some supplies, they return to the Thousand Sunny, only to find Pekoms missing and a warning to "turn back" scrawled in the bathroom. Unfazed, Luffy declares that things have finally gotten interesting, and that they will continue ahead.

Elsewhere, on Broccoli Island, Germa 66, led by two members of the Vinsmoke Family, are shown bringing an end to a 2-year civil war on the island. One of the Vinsmokes is shown disdainfully executing a soldier, remarking that his war was going to make him late for Sanji's wedding. After confirming receipt of their payment for defeating one of the sides, the two Vinsmokes contact an unseen individual via Den Den Mushi and learn that Sanji has already arrived on Whole Cake Island. The elder Vinsmoke comments that he can't wait to see Sanji again, but is called out as a liar by the other; they promise to arrive on Whole Cake Island the day before the wedding.
