Obitos MS is connected to all three of his consiousnesses, because of the fact it is on his Zetsu side.
Kamui's dimension, is the demension of Zetsu's conscious, aka nothing, pitch black.
Now that Obito is connected to the Juubi physically, the dimension kamui harbors more surprises.
(Madara can connect to Juubi thanks to Orochimaru implanting Hashi's face)
Going back to Shika-Ino-Cho, these three people will battle with the three main antagonists
Choji will hold off Juubi
Shikamaru will hold off Madara from doing anything.
And Ino will go into Obito's mind, having Obito now be connected to four consciousnesses.
Here the key to winning is kakashi - naruto, and Ino - obito linking to kamui and something happening in that demension rather than the NarutoVerse.
But this is only for Juubis aka Zetsus defeat, not Obito or Madara's.
Awhile ago I made a thread regarding as Obito as the Juubi and not Obito, giving my thoughts and explanations
I'm confused... How is choji going to hold off the juubi? And how is ino going to take on three consciousnesses at the same time?
For one, choji couldn't hold off the gedo statue with full chakra. As for the other, I just don't see ino to be as strong as you are implying. She's hot, but not that strong
Lol ino taking consciousness, she already did it once with the bijuu dama, she could do it again
Choji well it doesnt have to be holding the juubi forever, all it takes is one second for shika ino cho to execute
