Well, it was great, breath taking and real at the same time master piece which you typed here.
Perfect characterization, great pace of plot and explained in excellent and straight way closing any unclosed points of the plot. It takes really genious to remember about everything and yet put it in well structured prediction.
Aside of that, you really put your unique way of thinking to work:
I mean you the one who remember Sasuke's crimes part and wanted to settle it, speaking about it I wonder how Kishi will approach that topic.
Spiral Zetsu's arrival athough seemed random at first, when I completed reading I see now that everything make sense Spiral Zetsu arriving there, helping them and finally being revealed to work for Toneri Ootsutsuki mysterious villain of "The last" movie.
I really like your approach here as it strengthen connection between the movie and the manga plot. Yeah by making Toneri appearance in the manga Kishi could make him canon character no matter how much people would try to deny. The problem stays from where Toneri came and where he has been all this time ?
I would guess, Kaguya after eating forbidden fruit somehow caused rest of Ootsutsuki to power up as well... or maybe they have so mysterious unkown connection. She was afraid of them interrupting or trying to stop her so she sealed them in one of dimenssion or maybe frozen or blocked by special barrier so they lived their own life there waiting for Kaguya's fall.
But KCMNaruto, Kaguya was sealed once... so why they didnt escape then ? Because Kaguya somehow transfered her restriction power to Hagoromo and Hamura, so as long as one of them cling to this world, they were trapped until Hagoromo left.
In short perfect projection of what we can expect from last chapters of the manga
Enjoyable read and man really put your talent to work as you can be great mangaka
Also I would like to rep you for the efforts too bad I can not now ;(
