"One Piece" chapter 842 saw Luffy and Nami team up to take down Cracker, the one person that was standing between Luffy and rescuing Sanji from the rest of the Vinsmoke family. In chapter 843, Luffy and Nami are rumored to launch a rescue mission just as the Vinsmoke family start a battle against Big Mom.
According to Movie News Guide, the chapter will see Carrot and Chopper finally escape from the mirror maze and find themselves somewhere within Big Mom's castle. This will allow them to reunite with Luffy and Nami so that all four of them can work together to free Sanji.
However, complications will arise because the Big Mom pirates may be fighting the Vinsmoke family. Sanji, a member of the Vinsmoke family, but also their prisoner, was set up to marry Big Mom's daughter, but Niji and Ichiji started talking about Big Mom behind her back, causing trouble.
The two stated that Big Mom was fat and ugly and that they felt sorry for Sanji because he had to marry Big Mom's daughter, who was rumored to be just as horrid as her mother. Big Mom caught word of this gossip and threatened that she may cancel the wedding. When the Vinsmokes arrive for the wedding, they'll discover that they've walked into battle.
During the chaos, it is speculated that Luffy and his allies will help break Sanji out and help Reiju and Lady Pudding in the battle.
Big Mom and the Vinsmoke family won't be expecting Luffy since they placed Cracker to stop him from coming. However, back in chapter 842, Nami used her powers to summon rain and weaken the biscuits that Cracker kept using. This made it easier for Luffy to eat the biscuits and overpower Cracker in direct combat.
"One Piece" chapter 843 is scheduled to be released this week.
