Even so he's standing right next to the forth previos Kages he looks more than calm and indifferent .
It's getting like Madara for who The Infinity Tsukoyomi is everything he ever wants it yet he doesn't give a **** about this war.
In Sasuke situation is to find his truth but he acts like a swagger jagger (LOL).
He's not even impressed of the RDS, and like Madara he's getting more confident over his power even so Oro is controlling 4 Kages that might end up against him...
