[The truth is simply that Minato doesn't know that birds in Sakuya's world still use 'everyone' in daily conversation, and that he has a tendency to pick up the habits of his friends.

Oh well. He blinks when Sakuya asks about his Persona again but is otherwise unfazed, as it's not an unusual question in this sort of place.]

So it's just that birds have taken over and learned from watching humans...Only some people are capable of doing this in my world, and I can't say whether that's a good thing. [Not all Persona users were good after all, and in a sense one sacrificed themselves for such power.]
