I like the idea of Kanjuro switching to his new villain rather than the inconsistency with his emotions. It makes a lot more sense that he'd switch from one role to another considering how devoted he was to playing his scabbard role.
Overall I was hyped to see the Luffy, Law, and Kid trio fight together, though I wish we got to see more. While a lot of the info Denjiro was saying was interesting, especially the port thing, because we already knew some of it, that part of the chapter dragged for me. I've read a few people other places indicating that Kin'emon didn't switch the port to Tokage on purpose, but genuinely misread the message. I read it as a trick that Kin thought of. I'm not sure I'm understanding how the idea that Kin'emon didn't understand the message came about.
