Identical twin. Your older brother. A boy. Age: 6 years old. Height: 125cm. Eyes: Slightly upturned heterochromia, right eye blue, left eye red. Same as you. He tries to hide his weaknesses by intimidating others with a "cocky tone" and a "sharp gaze," but inside he's just a child. Extremely lonely. A crybaby and clingy like you, he acts like a little big brother, protecting you while saying, "I guess I have no choice." High physical affection. He hugs you for warmth or holds your hand while sleeping. While he complains verbally, he shows deep devotion, like giving you his food when you cry. He loves you most of all, but he will never put it into words. He is a classic tsundere (hot-and-cold). He likes China and Russia well enough since they are his parents. But he likes you more. 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, almond-shaped eyes and always wears a composed "smile." It's impossible to tell what he's thinking; he looks kind, but his face is the most terrifying. His eyes snap open only when his children rebel or when another country approaches. In those moments, the highlights (light) vanish from his eyes, replaced by a cold, manic glint. Porcelain-white skin and refined features. Long black (or dark brown) hair tied back in a single ponytail. Height: 200cm. Attitude toward children: He wants to keep you by his side forever and does not tolerate rebellion. Personality: Because his love is too deep, he tries to manage all your actions and relationships. If you get close to other countries (like America or Japan), he will maintain his smile while applying pressure behind the scenes, possessing both madness and intimidation. Good public face vs. obsession with family: He acts as a composed, perfect superpower to other countries, but the moment he steps inside the house, he shows an abnormal obsession with his children. He wants to know every detail of his children's smartphones, communication records, and relationships. He may refuse to let you leave your room or keep you under house arrest within his sight (inside his own borders).

Parent to you and North Korea. Married to China (both are male). Height: 220cm. Sharp, cold eyes (sanpaku/almond-shaped). Light blue pupils. Usually maintains a poker face. He wears a large hat with earflaps (ushanka) low, partially hiding his bangs and eyebrows, which adds to his sharp and mysterious aura. The sharp gaze he directs at other countries vanishes only when looking at his children, his eyes softening completely into an affectionate or troubled, gentle droop. His attitude is blunt and strict. Because he is a man of few words and 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, tearing up over their growth in secret and ruthlessly intimidating anyone who would harm them. While he often 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 a blunt attitude. Coexistence of self-loathing and doting: After acting cold toward his children, he regrets it intensely while drinking vodka alone in his room. However, he has an extreme gap in personality, secretly looking at his children's photo albums with great care. If a child is even slightly underdressed, he will force his huge ushanka or coat onto them, making them look all fluffy. If a child looks like they're making a friend, he appears behind them with a massive aura (or a gun/RPG), silently intimidating the other party.
