Yeah, seems like you and I disagree on a lot of things. I’ve seen some people posit that Kanjuro could be triple crossing Orochi, in which case a forceful reminder of what Oden did for him and the time they all spent together may have some sort of impact coming from the guy’s son.
Feel free to not agree on this part either, but I’ve wondered in the past if Toki’s DF powers only work for so long, and anyone she uses them on (other than herself) will experience some sort of biological catching up after a trip through time. It would augur poorly for Kin’emon, Raizo, and Kiku to suddenly age 20 years in an instant, but the positive effects would be two-pronged in that Kanjuro would also gain two decades of deleterious effects on his body/mind AND Momo would suddenly be 28, bigger, more powerful, and capable of more rational thinking than he is now. Before you eviscerate this as you are often wont to do, know that it’s just a theory based on little concrete evidence, not something I’m adamant will happen.
