Lol I don't speak a word of Japanese but it's an interesting language all the same from the little I've learned here and there.  As for Igor goes, I know he normally only addresses the main guy, but he could come to us all one at a time or all at once whether or not we've awoken to our power yet or not.  He is one of those rare characters that is key to the entire Persona story and yet he does not belong at the same time.  If that makes sense let me know lol.
