In both his and his brother’s character notes, it’s said
that if their curls are pulled, it will cause an involuntary physiological
(bodily) response. Italy Veneziano will say “Ve”, whereas Romano will make a
purring “chigi” sound.

We know that the different parts of a nation are reflected
in their human body. For example, America’s Nantucket or Austria’s Mariazell
ahoges. I say this because I believe that the physiological and verbal response
pulling the curl causes is in reference to a specific body of land, or rather a
part/ governmental organ of the nation.

Yes, “ve” is also an Italian verbal tick/ dialect, but what
you’ll see with Hima is that he likes to play around with words, give them double
(sometimes several) meanings, and make puns out of them. In Italy Veneziano’s
case, I believe the same logic applies.  

In other words, ‘ve’ could be attributed to the dialect and the city of Venice, which is commonly
believed to be North Italy’s first title as a personification. Although, if it
is in reference to a dialect/verbal tick, North Italy doesn’t say it nearly as
much as China does with his “aru”, which makes me think of it more in terms of a
reference to a body of land, rather than speech.

Anyways, in Romano’s case, I think it’s a reference to the
Palazzo Chigi in Italy’s capital, Rome. It’s where the Prime Minister of Italy
resides. The point here is that we already know that Romano does his fair share
of work for his government.

If that’s the case, then this reference only reiterates his
purpose as a second personification for Italy. This, of course, is in addition
to him representing the cultural differences of those from the southern regions
of the nation.

Further, we know that Ancient Rome left behind a legacy.
Italy inherited his charm, artistic aptitude, and wealth. Meanwhile, it’s not
very clear what Romano inherited from Ancient Rome… not unless you do a bit
of digging. What I’m arguing is that Romano inherited the role of governance
from his grandfather.

That doesn’t mean to say that North Italy doesn’t do his
share of government work either, because he does, just not nearly as much as
Romano nor with the same amount of commitment.

So? What about them hints?

When visiting Italy from heaven, Ancient Rome remarks that
Rome (as his capital) acted as his heart. Well, what if Romano inherited that?
Italy Veneziano is likely a reference to Venice as stated above, and as such,
Romano is just as likely to be derived from Rome – where the governing happens.

If you take a closer look at Ancient Rome, he resembles both
Italy brothers depending on the emotions he’s experiencing.

It’s not just Italy Veneziano who looks like Ancient Rome. Some of Romano’s expressions makes him a near clone of his grandfather.

Hard to tell the difference, right? Overall, it would seem
that Romano inherited quite a bit from Ancient Rome, contrary to popular
belief.
