There has been no confirmation for when chapter 839 of "One Piece" will be released because the team is currently taking a breather. Spoilers for episode 839 have been released, and at the center of it is the Vinsmokes family.

Spoilers for "One Piece" chapter 839 was released in MangaSpoilers by Oro Jackson. The chapter is given the title, "I Lived Under Your Crap-roof." Ichiji and Niji, along with Reiju, joke about how funny it would be if Sanji died an unhonorable dog's death. Sanji is provoked by this and orders Niji to finish all the food on his plate. Niji describes the food  as terrible and refuses to finish it all. He then throws the plate to head chef Cosette, but Sanji prevents it from hitting her. Sanji then finishes all the food that Niji spilled and gives thanks to Cosette. Niji is annoyed by Sanji and opts to kick him but was forbidden to do so by Judge. Cossete is knocked down by the wind pressure from Niji's kick and Ichiji calls Sanji a disgrace for the Vinsmoke family. Sanji is enraged by this; he tells them that royalty who don't care for their subordinates and disrespect women are against his principles.

Meanwhile, Judge threatens to kill Zeff, the head chef of Baratie, if Sanji will not obey him by marrying Charlotte Purin from the Big Mom Pirates. Sanji later finds Cosette dead, swimming in blood in the castle.

Since the Vinsmokes and the Big Mom Pirates have created an alliance, the meeting between them is expected to happen in chapter 840, according to Hall of Fame. Upon meeting, Charlotte will tell Sanji that she doesn't want to marry him, but is disappointed to find out that Sanji cannot disobey his father. Arriving at a dead end, Charlotte leads Sanji to the castle prison where Jimbe is waiting for him.

Sanji also discovers where the Germa 66 soldiers are being kept.
