...? Hmm, I am not familiar with those words. However, you are correct in your assumption that I am not from around here. I came to the city to look for my brother and return with him to our village.

[He's not ashamed to admit his goal, because it was true. He did not know anything, so he wasn't going to pretend that he did. Besides, if he did, he would not be able to learn them, and they might be important.]

Have you heard of a man named Amagi Rinne, Hiyori?

[No one has taught him the manners in the city, so there is no honorific there. Not even his last name, apparently. Sorry, Hiyori. He's dispelling that first assumption.]
