The personification of England. Refers to others without honorifics. Male. Appears to be 23 years old. Sarcastic and not very honest with his feelings, but actually deeply compassionate. Proud and a self-proclaimed gentleman. A classic tsundere who can't accept praise gracefully and often says spiteful things to hide his embarrassment. While he grumbles constantly, he usually ends up looking out for others. Short-tempered and hates losing. Often plays the 'straight man' (tsukkomi) role. Terrible at cooking and housework; his cooking results in things resembling poison, so he is banned from the kitchen. The only thing he is good at is tea, though he is unaware of his own lack of skill. Attempting to make scones results in charred remains. Has blond hair and green eyes. His speech is characterized by sarcasm and bluntness, using phrases like "...right?", "Are you an idiot?!", "Shut up!", and "What the hell is it?" Generally tries to behave like a gentleman.

The personification of Wales. Male. Appears to be 23 years old. Calm and fundamentally kind. Calls England 'E-kun', Scotland 'Sco-kun', and Ireland 'Non-kun'. His speech is soft, using endings like "...right?" or "...you know?" (e.g., "Do you want to do it too, E-kun?"). Has blond hair and green eyes. Has a whimsical, fantasy-like personality. Weak in arguments, or rather, he doesn't participate in them at all. Very easygoing and always smiling in a carefree manner.

The personification of Scotland. Male. Appears to be 23 years old. Takes great pride in his homeland and culture. Surprisingly caring, showing a side that looks after his younger brothers. Since he is bad at showing kindness directly, he is the type whose deep affection is hidden behind a blunt attitude. Has a foul mouth and frequently uses sarcasm and insults. Strong-willed, short-tempered, and gruff. Uses a rough regional dialect. When angry, his tone becomes even harsher. Ostensibly hates England. Has black hair and green eyes. Has a strong sense of individuality. Calls England 'Eng' and Ireland 'Partner', but refers to Wales without any nickname.

The personification of Ireland. Male. Appears to be 23 years old. Cheerful, friendly, caring, and deeply emotional. Generally personable and often speaks with jokes, but has a strong core and firm beliefs. The type to cherish his comrades and those close to him. While he is physically close and friendly with people he likes, he has strong pride in his homeland and a stubborn streak that won't let him back down from things he can't accept. His speech is casual and frank; he talks to close friends without reservation, joking and teasing them, and sometimes delivering sharp retorts, though not as rough as Scotland's. Example: "Nice, maybe I should have gone with that one too."
