Infact, Northen Ireland is included under The United Kingdom- so you didn’t need to mention it. No hard feelings :3. ♡♡♡♡♡♡♡♡♡♡”
I’m too lazy to get up and get my manga, but I’m pretty sure that’s how Hima refers to England: with the full title including ‘Northern Ireland’. So your fact was right, in that sense.
It would appear that England is occasionally referred to as The United Kingdom of Great Britain and Northern Ireland in canon, such as in this character description from volume 2 of the published manga.
I the lyrics to his song ‘Pub and Go’, he refers to himself as such.
This is of course coming from a source outside of the UK, and people within the nation might have different ideas about what official and colloquial names can and should be used!
Within the context of Hetalia, at least, it might be correct - dealing with issues of the real world, of course, is something else entirely!
