I wonder why this volume didn't include Puding siince she is Big Mom daughter. Well expect great art for her in later volume (and expecting her to be big part in this arc)
It's possible that Oda is waiting to draw her with the third eye.
Or he wants to draw her with a wedding dress.
Or both.
I'm more surprised by the missing Galette. In this volume she's more important than Opera and Mont d'or….
