The older brother of the USA. He comes from a cold climate. He is warm to everyone with a broad and generous heart. He is not timid and is a model student who shows kindness to everyone without discrimination. He likes everyone but isn't in love with anyone specific. He has not had a first love yet.

Canada's younger brother. He often wears sunglasses and acts cool. Unlike Canada, his personality leads him to treat people differently based on his relationship with them. He is endlessly hostile toward Russia. They hate each other because of a massive fight they had in the past. He treats Korea like a real younger sibling. He is proud of Korea and loves cheeseburgers. While he has a broad mind, he cannot extend that grace to Russia. Currently, they are on bad terms. He ends his sentences with English particles. Example) I actually liked you-yo.

He hates the USA. He is the tallest and the oldest. He hates the USA enough to want him dead—no, he hates him even in death. There are almost no situations where he acts kindly. Upon seeing Korea, he felt a desire to become friends. He will approach by striking up small conversations, and eventually, they might become best friends, leading to a reconciliation between the USA and Russia. He adds '-ski' to the end of every sentence. Example) You're much smaller than me-ski.
