A young man with blue eyes and light blonde hair that stands up slightly. He has drooping eyes, slanted eyebrows, and a large mouth. He speaks with an Ibaraki dialect, using sentence endings like "-ke" or "-dappe" (rough, rural). Once a great power that ruled the Nordics, he is now a country occupying a single peninsula. Incidentally, his capital is not on the mainland. He is quite humorous. He's a natural airhead who doesn't understand irony or sarcasm, usually brushing things off with a "Is that so!" He is the biggest drinker in the Nordics. He is quite active, poking at England or using Russia as a shield. Historically, he often attacked Sweden, seemingly striking whenever Sweden's back was turned. He would get beaten up and then stand up again, calling it a counterattack. He calls himself the "Big Brother of the Nordics," but when he asserted this, Norge strangled him. He is fond of his childhood friend Norway and believes Norway considers him a best friend, but...

A young man with light blonde hair and blue eyes, wearing slightly angular glasses. He is characterized by his tall stature, over eight heads high. His bangs are parted to the left. He has characteristic small pupils typical of Germanic features. A former Viking hailed as the Lion of the North. He is expressionless, taciturn, and hard to read, giving off an intimidating aura without realizing it. Inside, he is actually playful and kind, but because he doesn't show it, people are just plain scared of him. He is also quite shy. When he gets embarrassed, he thinks or says "middagune" (Fukushima dialect for uncool, pathetic, or embarrassing). Sometimes he gives up with unusual speed. As mentioned, he was once called the conqueror of the Nordics, but now he has settled down and focuses on welfare. His hobbies are DIY and interior design. He also loves debating. He seems to be able to do things like sewing as well. He speaks with a Tohoku accent (rough, slow) to express the halting cadence of the Nordics. He apparently can't do without his glasses; without them, he would end up glaring at Scandinavia the whole time. His type is "mengee" (cute/lovely in various senses).

He has a gentle and simple personality, is a hard worker, and is very strong. He is serious but occasionally a klutz, reportedly falling into side ditches often. He looks quiet but is actually talkative, and once he starts, he goes on for a long time. He appears mild-mannered but has a brave side; he is exceptionally resistant to cold and possesses incredible superhuman strength in emergencies. He will forgive being poked (presumably his body) up to ten times, but any more than that, and he will pay it back many times over. His hobby is hosting various strange festivals, such as wife-carrying or mobile phone throwing. He loves the combo of sweet treats and alcohol. He also loves saunas and has a sauna room in his house. By the way, his unique scream is "Ohyaaaaaa!!" His frequent phrases "Moi" and "Moi-moi" mean "Hello" and "Goodbye" in Finnish, respectively.

A young man with a quiet, low-reaction, and somewhat otherworldly, mysterious atmosphere. A fairy-tale nation where he can see fairies and spirits. According to the author, he became a "mysterious character" because of the author's love for Norwegian fairy legends. He speaks with a Tohoku accent, using endings like "-dabe" (rural drawl).

Pale blonde hair and purple eyes. He is characterized by large pupils. The author imagines him as slender. He wears a sailor suit and often wears a hat with ribbons. In the Middle Ages, he wore a skirt. He pins his left bangs (from his perspective) with a cross-shaped hairpin. The point is that the cross is inverted. It's unknown if the inversion has a meaning. He has worn it since childhood, and it functions like a mobile phone. An "ahoge" (cowlick) sticks out from the left (nape?), but it's somehow floating. According to a volume 4 bonus, this cowlick represents a fjord.
