Luciano Vargas is the leader of the family and head of the military forces. He used to be a sweet and lovely child when he lived sheltered by Grandfather Roma but his centuries as slave under Austria changed him turning the country in a distrustful man who isn't afraid to hurt others nor to get injured. He seems to relax only around the other Italians and allows himself to let his guard down only when he's alone with Flavio. He has a dangerous obsession with sharp blades and poisons.
Cuteness incarnate (At least according to Luciano), Flavio spent most of his life as Spain's slave but as traumatic as the experience has been he retained his optimism and kindness. He can be found socializing with humans in the streets of Firenze, painting, singing or playing instruments, other countries laugh about it since none of his skills would be useful in battle but for South it's incredibly important to keep art alive in a nation that mostly focuses on its army. He suffers of haphephobia and there are only few people who are allowed to touch him.
Meet the country who managed to buy itself from Luciano. Born with a gift for businesses Seborga managed to use the law in his favor and declare his independence, impressed by his skills and his bravery North decided to cooperate with him instead of crushing him. "Sebi" takes care of turism and trades, making sure the Italian economy keeps growing, and he's the one who works on keeping the relationships with other countries as positive as possible, at least in time of peace and if he has interest in them.
Not an independent nation, Vatican City is the religious head of the country. Older than the other members of the italian family, Vatican didn't choose a monastic life for herself, nor she choose to hide her gender and pretend to be a man but when the church found out their representation was supposed to be a nun they forced her into a farce that lasted for centuries. Now she seems satisfied that at least her brothers know the truth and keeps living a simple life giving all she has to the poor, spiritually helping those in need and... devouring soap operas, dreaming to find her special person, someday, and elope with them.
Marialuisa is the little princess of the family, or at leasts she calls herself one. Her existence is a mistery: San Marino isn't independent nor seems to have any form of internal government but somehow she is there, often running around home with a crown on her head or asking people to be her shining prince. Everyone tends to spoil her with threats and she seems inoffensive enough even for Luciano so she's just... there. Part of a poor city with no real authority, if asked why she isn't put in line Luciano will only reply that "he knows better than raising a kid with a deadly grudge toward him."
