I knew this would be a problem for this arc. Everything will move at snails pace because Oda needs to cover, quite literally, 60+ different character perspectives. My guess is they will appear to help Shinobu if she runs into more trouble.
This is why we haven't seen Sasaki, Drake, Who's Who or Black Maria in many chapters. Even Page One has been curiously missing for a while now.
This is what happens when you can only generate 15-17 pages on a pseudo weekly basis lol.
I really don't expect Wano to be anything under 140 chapters and I feel like that is low-balling it if I'm being brutally honest.
