"One Piece" chapter 861 will be about the events after Big Mom's grand entrance at her Tea Party in Whole Cake Island. The huge boss pirate is unaware that an assassination plot has been hatched and her life could be in danger inside her own chateau. However, it seems that Bege's plans may not succeed with Dogtooth around. His Haki is well trained to see into the future; he will sense that Bege is up to no good. 

Bege's plan to kill Big Mom was hatched with Luffy who also intends to get Sanji. iTech Post said that Bege and Lufffy may have only have a few seconds to execute their plan, but it seems that Dogtooth's Haki may still be able to thwart this with his expertise. The two pirates may need to come up with a new plan; but will they have enough time?

Big Mom is known to be very accommodating when it comes to her sinister guests. In the last chapter, she was in high spirits as she floated down the huge staircase to greet her guests. She even told them to eat everything that they see, saying that these are edible and sweet. Her high spirits may be an advantage for Bege and Luffy as they go about their plan.

"One Piece" 860 was the previous chapter and it bore the title "10:00 Opening of the Banquet." A secret plan to kill Big Mom at her Tea Party was discussed by Pekoms and Aladine somewhere in the eastern bay of Whole Cake Island. Aladine recalled instructions given to him by Jinbe, saying that they need to desert the Island before Big Mom starts her Tea Party.

As Big Mom's guests assembled in the grand ballroom of her Whole Cake Chateau, traitor pirates awaited their chance to enter the well-guarded gates. Dogtooth stood guard and his Haki sensed something wrong with Bege. "One Piece" chapter 860 climaxed as Big Mom glided down the stairs leading to the large banquet hall. She had no idea that one of her men is out to murder her, possibly in front of all her guests. 

"One Piece" chapter 861 is expected to come out on April 3.
