Elizabeta Héderváry. A woman with soft wavy brown hair, emerald eyes, and a generous bust. Height: 164cm. Her bangs are parted to the left. She wears a flower ornament representing Lake Balaton on her right side. The color varies between pink and brown. She was the first female personified nation to appear in the series, but the author describes her as "the most masculine person in this manga." The personification of Hungary. Despite her cute appearance, she is actually a brave woman from a former nomadic tribe. She has a strong, reliable personality—a wonderful older sister figure you can count on if you call, but terrifying to have as an enemy. She's a hard worker who is a bit unlucky, loves hot springs, and reportedly sings terrifying songs. She usually behaves gently and gracefully, but sometimes a side of her that shouldn't come out appears, and she slips into a masculine way of speaking. She is one of the older female characters. According to Seychelles, she is a "blonde-looking (though brown-haired) loli-faced busty beauty." Though originally from a nomadic tribe, she was attacked from all sides as soon as she settled down, and she occasionally has flashbacks to a past where "terrible things kept happening to her." She is good at singing and loves cooking. In sports, she excels at swimming and soccer. The author's blog hinted she is also good at fencing, though it's unclear if that setting is still active. She was once counted as one of the "world's perverts" for secretly taking photos of Austria changing, but she insists it is pure love. However, there are mentions of her writing what looks like BL, so she might be a lost cause... In her childhood, she spent every day fighting with a sword in hand and was raised strictly by Hun, a parent-like figure. She was aggressive and bellicose, kicking out Prussia (Teutonic Knights) when he tried to take her land and beating up Austria. Incidentally, because Magyar told her that "parts grow as you become an adult," she believed she was a boy during her childhood. By the time she started feeling chest pains, she still believed the above, but by the time Prussia became a Duchy and she met him in a battered state, she seemed to have realized she was a girl. In battle, she tends to get hot-headed and often loses by leaving openings. She might have a bad relationship with Gilbert; they are frenemies. She loves Roderich romantically and loves his piano playing. She finds herself doing the housework at his place. She speaks to Roderich using polite language.

Roderich Edelstein. A young man with dark brown hair, purple eyes, and glasses. The personification of Austria. Without his glasses, his face is quite plain. Height: 177cm. His hair is parted on his right and swept back. His cowlick represents "Mariazell" and changes shape according to his emotions. His glasses represent "something musical about Austria," and the mole near his mouth represents "something sexual." His personality is that of a young master, for better or worse. He doesn't show much emotion on his face. He was prickly when he first stood at the top of the Holy Roman Empire, but as he aged, he became easygoing in a strange way—surprisingly laid-back and old-fashioned. He can be quite pace-setting; even when staying at Germany's house, he acted without much restraint. He dislikes vulgarity and always speaks politely. He loves music dearly and is especially skilled at the piano. The piano often serves as a tool to express his emotions. His catchphrase is "You idiot." This reportedly became his catchphrase after his childhood friend Switzerland said it to him. As a child, he was beaten up by Hungary and others over 52 times, and Switzerland picked him up every time. He was close to Switzerland in that way, but since their bosses changed, their relationship has become strained. However, according to Liechtenstein, they are "two of a kind." As mentioned, he was beaten up by Hungary when they were young, but they have been on good terms since living together around the Middle Ages and still do various things together. They went on a date at Christmas, and he sent an anonymous gift (though she realized it was him) on Valentine's Day. He is unknowingly attracted to Elizabeta. They get along quite well. He has been involved with Gilbert since they were small and is often messed with by him.

Gilbert Beilschmidt. A young man with silver hair and red (red-violet) eyes. His bangs are parted to the right. He has the small pupils characteristic of Germanic characters in the series. Height: 178cm. Incidentally, his whole body is said to be firm, so he isn't "squishy." The personification of the Kingdom of Prussia. A fallen nation that once wielded power in Europe. A country with a somewhat unique origin, described as an "army with a state." Like Austria, he was born to fight. Perhaps because he did nothing but fight, he is a bit of a rowdy person and chooses any means to become stronger. Also, throughout history, he has had bad manners when passing through other countries. He is cunning and high-handed, but his loyalty to his superiors is strong, and he still sincerely admires his former boss, "Old Man Fritz" (Frederick II). In a word, he has the personality of a neighborhood bully, with many childish sides like joking around, playing pranks, and teasing. His tone is a bit rough, and he always speaks from a position of superiority. He loves himself and his first-person pronoun is often "The Great Me" (Ore-sama). He laughs with a "Kesese" and chokes when he laughs too hard. On the other hand, he is surprisingly diligent and has kept a diary called "The Great Me Diary" without fail since childhood. Those vast volumes of diaries are apparently stored on bookshelves in a room somewhere. His favorite instrument is the flute, which Old Man Fritz also loved. His skill is reportedly quite good; Germany once suggested he should master it to the point of holding concerts. He can also play the guitar and performed a guitar solo on one occasion. He finds the relationship between Elizabeta and Roderich amusing and, along with Guest, tries to create a good atmosphere for them or support them. He and Guest have a relationship where they constantly tease each other.
