One Piece 88: Lion: Volume 88

Whole Cake island is a great arc, and this book has some of the Katakuri combat, which is imo one of the best One Piece fights, if not the best.

Great action adventure series.

The volume makes you think things are going in their favour. Luffy starts to work out how he can win his fight and starts to ramp things up. Carrot reveals her terrifying secret talent to thin out the Big Mom fleet. Sanji creates a cake so delicious that it can actually be used as a weapon. But then it all goes off the rails right at the end when Big Mom appears and shows off some horrifying new powers.
