The previous chapters of "One Piece" have seen the Straw Hat pirates still struggling from Big Mom's henchmen. Nevertheless, the Straw Hat leader, Luffy, is determined to finish the battle in the upcoming chapter of the manga series. Based on the storyline predictions for chapter 888, it is likely that the protagonist will be ready to enter the Mirror World once more to fight Katakuri, especially since his Haki recovery is nearly completed.

The fans have been talking about the recent developments in the "One Piece" manga, and the demand for a second round between Luffy and Big Mom's lieutenant, Katakuri, is getting high. According to the One Piece forum, it is possible that the second face-off of the two powerful warriors will happen in "One Piece" chapter 888. In the previous chapter, it was impossible for Luffy to launch another barrage of powerful attacks against the enemies, especially as his powers were depleted after his first fight with Katakuri.

It is likely that Luffy will finally regain his Haki in "One Piece" chapter 888. The pirate might be able to recover his strength within such a limited time, given that he has been avoiding direct battles with Big Mom's soldiers. Instead, Luffy has been shown running away from the enemies, but in the next chapter, he will be ready to face another strong opponent once again.

Luffy entering the Mirror World for the second time to fight Katakuri is also supported by the fans in Naruto Forums. Not only will Luffy have another bloody battle with the Sweet lieutenant, but he is also likely to develop another powerful technique. If the rumors turned out to be correct, then the fans could see the new Gear 5th technique in "One Piece" chapter 888.

Elsewhere, the fans will know about the status of Sanji's wedding cake that he has been preparing for Big Mom. The female Yonkou's patience is getting shorter by the minute, and it is important to have the delicious wedding cake served in front of her before Big Mom decides to raise hell on the Straw Hat pirates. 

After the "One Piece" chapter 888 release next week, a Reddit poster claims that the manga will take a one-week break due to the Shonen Weekly Jump holiday. The hiatus is expected to start on Dec. 18 and end on Dec. 24.
