Jeez. Interesting.
Ididn't hoped for much action though. We all know Naruto and Sasuke as gods something along that line. But I kept my mind thinking that the villain would be something new and somehow would have an edge against those two. Call it nerf, call it plot restriction, I dont mind. That's all there is to it.
Nonetheless, I'll say this: It only just started. I bet there could be more, action wise, display of power those sort of things. It is too early to conclude.

Now about Sakura... This I will connect to potential Karin involvement.
Im not an enthusiast of Sarada being karin's child. But the last panels kinda gives me the impression that Sarada and Shin somehow had a similar past, that is, Sakura wanting to make sure of Sarada/Shin's welfare. But this is something of a long shot for me.
(i dunno maybe Karin asked Sakura to take care of Sarada afterall. But I dont see clear reasons yet so let's wing it)
I felt glimpses of SS status which were cut short by that miniature juubi.
So what if Karin is really involved with Sarada? (Ithought of deleting this part UGH)

Great Chapter Perfect score on any scale

It's great to see the plot finally moving and uncovering some stuffs.
What Im happiest about is that Naruto and Sasuke were held back. It would have been a bore if they defeated the enemy at such an early phase.
I am hoping for a steady development.
