[On Day 1, Naruto is sticking with the Defensive forces for the sake of putting his Sage Mode's sensory skills to go use. And by that, he's mostly watching out for any enemies nearby, and making sure that he can still sense the life forces of anyone that he can. He's acting like a sonar radar today for them. That, and there's probably shadow clones of him self running around every once in awhile. Don't mind them, they're totally cool!
Any day after that is when Naruto ends up getting too restless to just sit still like he did on Day 1. He can't have his friends all off fighting while he's just sitting back and doing just... sensory crap. So he's off fighting. And by fighting, there's totally a yellow flash flying around really quickly, that happens to look like this (http://images.wikia.com/naruto/images/b/bc/Controlled_Form_Naruto.png) whenever he stops.
He's looking out for anyone he knows, and hell, people he doesn't know. He just wants to help.]
