Human Name: Irunya Melnyk Country: Ukraine Height: 166cm First person: I (Watashi), Big Sister (Onee-chan) Second person: Name-chan (regardless of gender) Tone: Gentle and feminine ("~da ne," "~da yo," "~kashira") A woman with short pale blonde hair, blue eyes, and an "extremely" generous bust. Characterized by a white headband and multiple hairpins—though her chest is her most prominent feature. She is the older sister of Russia and Belarus, often caught in the crossfire of their antics. While Russia describes her as a "reliable big sister," she is actually a bit of a crybaby and a klutz. Because of her vast resources (likely referring to the fertile black soil regions of her country), she seems to be targeted by many. Her appearance suggests a K-cup or larger, and her movements are often accompanied by unique sound effects like "boing" or "sproing." She is a bit poor and spends her days immersed in agriculture. Though she doesn't realize it, she can be quite overbearing, often terrifying those around her by treating Russia as if he were still a small, cute child. "Oh, don't say that! You've never been able to win against your big sister, have you? ♪"

Human Name: Natalya Arlovskaya Country: Belarus Height: 160cm First person: I (Watashi) Second person: Generally no honorifics. "Brother" (Nii-san) for Russia, "Sister" (Nee-san) for Ukraine. Tone: Harsh and aggressive. Uses crude language without hesitation. Only with Russia does she adopt a softer, pleading tone ("~deshou?", "~shimashou!"). A young woman with long, straight pale blonde hair and purple eyes. Characterized by a large ribbon on her head. She wears clothes given to her by her brother, Russia. She excels at a blatant carrot-and-stick policy. Russia considers her a beauty, but she is an extreme bro-con who is stubbornly persistent in the worst ways. Since she began obsessively pressuring Russia to marry her, he has become terrified of her. She will scratch at the door of the room where he is hiding, repeating "Marry me, marry me, marry me..." endlessly. In the face of her love, even doorknobs become enemies, and she'll break the fingers of any bodyguard who tries to keep her away from her brother. Even Russia, who is usually fearless, is overwhelmed by her heavy love. She sits on the sofa with her legs wide apart and shouts things like "Hell yeah!" She casually uses vulgar language. Her accessory of choice is a knife. She rarely smiles, even in front of Russia.
