@OP - Yeah, I don't think we'll see Dan's Spirit Transformation jutsu. It must've been beastly, given he was even considering the dream of being Hokage. As well, he warned the alliance of it. Kind of disappointing that Tsunade and Dan never met up as well. It could've been like an Onooki vs. Muu situation, but with a different type of relationship (i.e. romantic, not teacher/student). Oh well, :shrug:
Peace
the edos aren't fully released yet and we dont know if kishi will troll us and make the edo release fail
lol, that would be a jerk move, after a substantial number of chapters were dedicated to this very process of ending IWR/ET in a fight with heavy weights possessing very little action to this point due to each side's restraints.
Of the Edo's, only ET Madara seems to know much about the jutsu, so perhaps he'll be able to escape it via plot no jutsu. With Kishi, I honestly never know for sure what's going to happen. When he writes, it's like he works with a pen in one hand and a pair of dice in the other, lol.
Peace
