It's difficult to convinced. The last we seen shinobu is in port grabbing momonosuke. Maybe something wrong happened to her or the old shinobu is just an image by kanjuro from the start (how is she can use devil fruit?)
Didn't see that twist coming. Also nice double spread on the last page.
Kanjuro should be grateful for the strawhats. If kotnfor them he's still stuck at Doffy's place.
crazy theory:
once momonosuke is on onigashima, kanjuro's role is over. he could perfectly play the role of kozuki oden and help momonosuke be the next heir to the throne. he himself said that he has no loyalty to either party and solely moves to play a role
Whew. That flashback was way too long. A lot of it was important to the plot and backstory, sure, but there was way too much going on. I feel like this needed to be broken up and doled out in tidbits over time.
