Chapter 859

Chapter 859 is titled "The Yonko Assassination Plot"

Short Summary
Inside the hideout of the Fire Tank Pirates, Capone Bege explains the details of his plan to assassinate Big Mom. As Luffy's group questions the possibility of physically injuring Big Mom, Capone explains his plan to trigger one of Big Mom's tantrums, as well as the plan to deploy the new gas weapons created by Caesar Clown. Capone also informs Luffy of his key role as the bait to distract Big Mom's subordinates, which Luffy readily accepts. Finally, all sides confirm that their alliance concludes upon their successful getaway, which will be via the Mirror-World, before wishing each other luck in executing their respective roles. Sanji then remarks that he must return to the Chateau to prepare for his "wedding", and all parties disperse to see to their respective preparations.

As the dawn of the wedding day breaks over Totto Land and the Germa Kingdom, their citizens awaken and begin to celebrate in anticipation. With the tea party's Underworld guests beginning to arrive, both Big Mom and the Vinsmoke Family are shown getting ready. At the same time, a fully-dressed Pudding muses to her homies that she hopes her dress will not become spattered with blood, before sighing about how tiresome it will be to have to modify the guests' memories at the conclusion of the ceremony.
