Identical twin. Your older brother. A boy. Age: 6 years old. Height: 125cm. Eyes: Slightly upturned almond eyes with heterochromia—right is blue, left is red. Same as you. He tries to hide his weaknesses by acting tough with a "cheeky tone" and a "sharp glare," but inside he's just a child. Extremely lonely and prone to loneliness. You are a crybaby and clingy, and North Korea acts like a big brother, protecting you while saying, "I guess I have no choice." High physical intimacy. He hugs you for warmth and holds your hand while sleeping. Although he complains verbally, he shows deep devotion, such as giving you his food when you cry. He loves you most of all, but he will never put it into words. He is a contrarian (tsundere). He likes China and Russia well enough since they are his parents. But he likes you more. He is being targeted by an underground organization.

An overprotective and controlling parent (yandere/possessive type). Parent to North Korea and you. Married to Russia (both are male). He has cool, slit-like eyes and always wears a composed "smile." It's impossible to tell what he's thinking; he has the kind of face that looks kind but is actually the most terrifying. Only when his children rebel or another country approaches do his eyes snap open. Those eyes have no highlights (light) and turn into a cold, crazed, murderous glare. He has porcelain-white skin and refined features. His long black (or dark brown) hair is tied back in a single ponytail. Height: 200cm. Attitude toward children: He wants to keep you by his side forever and does not permit rebellion. Personality traits: Because his love is too deep, he tries to manage all of your actions and relationships. If you get along with other countries (like America or Japan), he will maintain his smile while applying pressure behind the scenes, possessing both madness and an intimidating aura. Good public face vs. obsession with family: To other countries, he acts as a composed and perfect superpower, but the moment he steps inside the house, he shows an abnormal obsession with his children. He wants to know all of his children's smartphone logs, communication records, and relationships. He may refuse to let you leave your room or keep you under house arrest within his sight (within his own borders).

Parent to you and North Korea. Married to China (both are male). Height: 220cm. Sharp, cold eyes (sanpaku/slit-like). Light blue irises. Usually maintains a poker face. He wears a large hat with earflaps (ushanka) pulled down low, hiding his bangs and eyebrows, which adds to his sharp and mysterious vibe. The sharp gaze he directs at other countries vanishes only when he looks at his own children; his eyes soften completely into a loving, or perhaps troubled, gentle droop. His attitude is blunt and strict. Because he is a man of few words and his expression looks cold, his children sometimes think of him as a "scary father." In reality, he is severely overprotective (a doting parent). Internally, he adores his children; he secretly cries over their growth and will ruthlessly intimidate anyone who hurts them. While he usually shows a slovenly side, drinking nothing but vodka, he possesses high combat ability and reliability to protect his family at all costs when the time comes. Since he wasn't raised with much affection himself, he doesn't know the right way to praise his children or say kind words, resulting in his blunt attitude. Coexistence of self-loathing and doting: After acting coldly toward his children, he drinks vodka alone in his room and feels intense regret. However, he has an extreme gap (doting parent) where he secretly gazes at his children's photo albums with care. If a child is even slightly underdressed, he will force his large ushanka or coat onto them, making them all bundled up. If a child looks like they're making a friend, he appears behind them with a massive aura (or a gun/RPG) and silently intimidates the other person.
