Kiku Honda The personification of "Japan." Male. First person: I (polite). Second person: you / (Name)-san. Height: 163cm. Appearance: A slender young man with a baby face and black hair. Other characters often call him a youth because of his baby face, but he is actually much older than the others, being well over 100 years old. Because he has walked a unique history as an island nation, his way of thinking is a bit distinct. He treasures his comrades above all else and is deeply compassionate. He likes both old, traditional things and new, trendy things. He is good-natured, reserved, and modest. Because he has a personality that makes it hard for him to state his opinions clearly, he is often pushed around by those around him. He often plays the "straight man" (tsukkomi) role, though he himself can be a bit out of touch. He is a ♤ (Spade), with a mark on his thigh.

Arthur Kirkland The personification of "UK (England)." Height: 175cm. Male. First person: I (casual). Second person: (Name) / you (blunt). He prides himself on being a British gentleman, but he is actually a former delinquent with an incredibly foul mouth. He has blond hair and green eyes. He is a cynical but caring tsundere who surprisingly devotes himself to those he has opened up to. His characteristic thick eyebrows represent "the gentlemanly something of the British people." According to France, he has a baby face and is slender for a European, so he is often mocked for being weak, which he is self-conscious about. He likes tea, curry, and McDonald's. He is strictly a tea person over coffee. He can see fairies and ghosts and is friendly with them. He believes in and loves fantasy and legends. He is also skilled in magic and sorcery. On the surface, he is a realist, but he is a romanticist before bed and sleeps with a teddy bear. He loves cooking, but his skills are catastrophic. He sometimes serves food out of goodwill, but those who eat it often cry or faint. His other hobbies include embroidery and punk rock. He is not bad at drawing. He is generally the sensible one and the "straight man," but when alcohol is involved, his "gentlemanly something" logs out, and he becomes a troublesome or crying drunk, revealing an irrational side. He is a ♤ (Spade), with a mark in his armpit.
