Nation's name: Espana (or Kingdom of Spain)
Birthday: February 12th
National flower: Carnation
Human name: Antonio Fernandez Carriedo
Age: 25 (appearance)
A kingdom in southern Europe raised by the sun, bountiful nature, and the warm climate.
Used to be a super power nation that traveled around the world with its merchant ships--but was then tormented by England, beat up upon by a much younger America, and engulfed in poverty and war ever since he was stripped of his status as a super nation.
But, he seemed to have tide himself through those hardships with Espanola Optimism.
His personality is bright, loves people, and has a country-bumpkin-like atmosphere everywhere.
His dishes are TOMATOES TOMATOES TOMATOES! And sweets that aren't really that sweet.
Nation's name: Republique francaise (The French Republic)
Birthday: July 14th
National flower: Iris
Human name: Francis Bonnefoy
Age: 26 (appearance)
Was once a large nation in Europe that had the continent within the palm of his hand.
Ever since England was born, they have been at odds with each other and are always trying to see which one is better and be acknowledged as such.
Ever since Napoleon passed away, hasn't really been very good in war, but became a country known to attract tourists by wine alone (such as showing them to vineyards and to touring the process of wine-making).
Very proud, and prides himself for having the most beautiful language in the world. Loves beautiful things--of course, that includes both males and females.
Nation's name: Schweizerische Eidgenossenschaft (this is German for The Swiss Confederation)
Languages: German, French, Italian, Romansh, etc.
Birthday: August 1st
National flower: Endelweiss
Human name: Vash Zwingli
An eternally neutral nation that lives seemingly as a social hermit/recluse, surrounded by the grand Alps.
Even though Switzerland has an image of being peaceful, he is the biggest producer of guns in the world, has the biggest military strength and holds the world's wallet. With this, he is able to be the eternal neutral nation because other nations are unable to really lay a hand on him.
Was originally born as a nation from strong unions/treaties, but because he doesn't have many relations with other nations, he hates outsiders (foreigners).
He will work hard on a job until the very last detail is finished.
He also has a past achievement of being hired by the Vatican as a mercenary.
Nation's name: The United Kingdom of Great Britain and Northern Ireland (I am translating his name to "England" or "UK" purely because I have asked people from the UK and they said even the nation's name is pretty tricky/touchy.)
National flower: Narcissus, Tudor Rose
Human name: Arthur Kirkland (thanks to equivalent_t for this!)
Age: 23 (appearance)
A rainy empire that was once a pirate, now a gentleman (?)
Was once a subordinate of France, but after taking the top half of France's land and getting violent with him, it's spoiled their relationship and now they're fighting buddies.
As a former pirate, used to torment Spain and set up colonies here and there and everywhere. Was a pretty violent little boy.
Is cynical, hates to lose, and is slightly obstinate.
Seems to be cold at first, but is surprisingly devoted to someone if he becomes friends with that person.
Has a real potty mouth, but is not a bad guy.
Loves spirits/ghosts, faeries, magic and legends to the point where he has a list of spiritual residents as well as ghost tours.
Also, is a nation that keeps appearing on the news for stupid sex acts.
