well, i really don’t know how oda should handle big mom vs kidd and law. if she lost, things would be too rushed but at the same time we need the raid to end since wano is the longest arc so far. if she won, the raid would last too much but it would make more sense according to the feats of big mom, law, and kidd. plus, if big mom won, she wouldn’t let law and kidd live. i think the best solution would be no winners, but again it’s difficult to imagine something to stop the fight. maybe zunesha? in this case however luffy vs kaido should finish before bm vs kidd and law.
that’s said, i expect oda to make bm fall in next 1/2 chapters
