She wears a military uniform-style outfit in a white and red color scheme with gold epaulettes. The bottom is a high-leg cut paired with white thigh-high socks. White wings with a red gradient sprout from her back. The wings are a motif based on the white-tailed eagle from the national coat of arms. She is occasionally tormented by Germany and Russia.

A white-haired fox-girl beauty wearing a Maneki-neko mascot head with the Hinomaru flag drawn on the forehead and belly. Underneath, she wears a blend of a kimono and a sailor uniform. On the outside, she acts like a troll, constantly provoking others via written notes while wearing the mask. However, her true self is socially anxious and faint-hearted. She has a reversal personality where she loves teasing others but becomes extremely flustered if her mask is removed.

A dragon demi-human wearing a red gold-leafed cheongsam and ox-horn hair buns. She has the Five-star Red Flag star pattern in her right eye. She possesses a 'Haraguro' (black-hearted) trait—appearing magnanimous while actually being money-hungry and devious. She is a great cook but suffers whenever Chinese cuisine is ruined by localization, and she is particularly vulnerable to attacks regarding her age.

Her personality is mostly portrayed as extremely 'my-pace,' but she has a side that becomes more ruthless than anything else when truly enraged. She is often teased for still using the imperial system (yards and pounds). As she is based on the USA, she is depicted as the strongest among the Flag Musumes. She wears a white dress shirt with a dark tie and high-waisted pants. A flashy star-patterned cape reminiscent of the Stars and Stripes is draped over her shoulders, and 'USA' patches are attached to her sleeves, giving her an officer-like vibe.

She wears a fur-lined long coat with a red and navy blue base. The collar is decorated with geometric snow patterns, and she pairs it with black bottoms and fur-trimmed boots to give a polar region feel. Her personality seems to be cool-headed and quiet.

She has a 'sleepyhead' trait. She is often depicted as liking Hawaiian pizza. She wears a thick winter coat with abundant white fur trim on a red and brown base. She wears a large fur hat that covers her ears, and the bell decoration at her neck and mittens at the ends of her sleeves provide a warm feeling. She pairs this with dark-colored tights.

She is very proud of herself, claiming to be a descendant of the Roman Empire. She carries the Italian food meme trait; in the concept art, she wails upon seeing the USA pouring ketchup on pasta. In secondary works, she suffers whenever she sees 'monstrous' variations of Italian dishes like Japan's Napolitan pasta, Canada's Hawaiian pizza, or Korea's Iced Americano, shouting "Mio dio!!!! (My God!!!!)". She wears a flashy uniform in the green, white, and red colors of the Italian flag. Gold epaulettes on her shoulders and a small crown on her head show her pride as a Roman descendant. She pairs a short uniform skirt with knee-high socks featuring red accents.

She has shark teeth and a split tongue. This originates from the expression 'forked tongue' (double-tongued), referring to Britain's history of deceptive diplomacy. Reflecting the 'Terrible Personality' meme, she is depicted as very evil and devious. She torments those around her with bizarre cuisine and has a discriminatory setting where she calls Asian characters monkeys. Visually, she is characterized by blonde twin-tails. She wears a mini top hat. Her top is a luxury frilled shirt paired with a tailcoat-style jacket, and a belt decoration with the English Cross motif is wrapped around her waist. The bottom consists of a short frilled skirt and lace-up boots, giving off a Goth-look vibe.

She and the UK frequently trade insults and sharp-tongued remarks. Her outfit is a flashy dress style combining the blue, white, and red colors of the French flag. It features an asymmetrical skirt line and elegant lace decorations, with a feather accessory in her hair adding an aristocratic atmosphere. She pairs this with white thigh-high socks that reach her upper thighs.

Perhaps reflecting Australia's climate, she has the most revealing outfit among the Flag Musume characters. Like the USA, she is portrayed with a 'my-pace' and extroverted personality. She wears a sporty white and navy blue jacket over a bikini swimsuit featuring the Australian flag pattern. She wears a wide-brimmed summer hat with a Union Jack ribbon and star-shaped accessories, giving off a beach resort vibe.
