Link's kin perhaps? I don't know why, but the first thing that came to my mind was his daughter. That might be pushing it. I can see it being Zelda, but the character design looks perhaps like the child of the two if anything. God do I feel like I'm treading fan-fiction waters right now.. But what else could it possibly be!? This Zelda hype is already messing with my ability to function, let alone understand logic!
