"What is your name? Where are you from? What is your favorite food?"
Well, if it's what we expect it to be, then I'd guess that she asked him "Who are you?"
I'll give it to Manhiem because that is what I was wanting. I would have taken "What is your favorite food?" as well since Miharu does like to eat a lot.
