I am kin with two characters from Hetalia. The characters there are literaly countries as humans. So… would that kinda make me… countrykin? Because even though they look human and act human they can feel what happens in “their” country and one of them is actually immortal, so…?

Anon, if you try to seriously tell people you’re ‘countrykin’ you’re going to get nothing but mockery. Just because you can put a label on it doesn’t mean you should, in this case. Even so, you ID as the character, not the actual country.

I’d just put the two down as fictotypes if I were you and leave it at that.
