I was just rewatching the scene where Yozora and Sora meet. I don't know if this theory had been posted, but here goes:
First, Yozora mentions he looks different. He's familiar with body and hearts changing, probably memories too, to an extent.
Second, when our Sora identifies himself, Yozora thinks he recognizes him and then thinks he has to save him through fighting. Here's the inquiry: what if Yozora thinks our guy is actually a different Sora?
I'm pretty sure Sora can also be a girl's name on Japanese (because of Digimon season 1). Yozora is used to body switching and rearrangements. Thus, he could believe the girl Sora from his world is who he is fighting.
If she really was taken in that portal thing we saw in the opener for You Story, he could believe she was changed up into the Sora we've known for almost twenty years. Since his Sora has been screwed up, in his mind turned into a monster or whatever, he could be trying to save her by crystalizing her for a while until he can do some sort of restoration.
Now, he does say "I've heard of you." That would imply he's never met her.
Could be. Nomura had given us what? Six minutes total with the guy? He could be sarcastic, there could be a history, maybe they only had a couple minor communications, some other explanation. It's Nomura and he probably doesn't know yet.
One last thing to add to my theory: in FF Versus XIII, Noctis and Stella were supposed to be frenemies on opposite sides and lovers. Both Yozora and the Nameless Star, who I believe is agreed upon that she's the girl Yozora knows, believe the other has been switched up internally, forcing them to become enemies.
In short, my theory is that Yozora thinks our Sora is his girl, also named Sora. Their fight is a big misunderstanding that came about by serendipity.
