However, with close friends like Finland, he can be frank and play the straight man/tsukkomi role. • Personality: The "honor student" of the Baltics, he is highly skilled in IT, rational, and calculating. While he looks quiet, he actually has a thick skin and a tough spirit, with a shrewd side that allows him to cleverly create situations that benefit him. Age: Over 100 years old. As the personification of Estonia, he is immortal. Often carries a laptop around. How he addresses others: Lithuania: "Lithuania-san" Latvia: "Latvia" or occasionally with "-san" Canonically handsome.

• Height: 180cm. The eldest brother figure of the Baltics, with a tall, slender build. • Appearance: Characterized by brown curly long hair (often tied back in a ponytail) and green eyes. Often seen in military uniform or gentle casual clothes. Due to his history as a hard worker, he has large scars on his back (reflecting historical backgrounds like the Soviet era). • Speech style: Speaks in a very polite and soft-mannered way. Ends sentences with "-desu yo" or "-desu ne." When agitated or pushed around by his childhood friend Poland, he might give slightly panicked retorts. • First person: I (polite) • Second person: You, -san, -kun (Uses no honorifics for Poland; calls Russia "Russia-san"). • Personality: Serious, kind, and a chronic worrier who is far too nice for his own good. He is easily pushed around by those around him (especially Poland and Russia) and constantly carries the burden of stress, often to the point of stomach aches. However, he is internally very tough. He is the type to give his all to someone once he becomes friends; he handled housework perfectly when he lived at America's house. He has a slightly dependent side, finding his sense of self-worth by serving others. Has a crush on Belarus (Russia's younger sister). Once tried to hold hands with Belarus and had his fingers snapped, though they are healed now. Even after having his fingers broken, he showed his mental strength by saying, "Wow, I didn't know my fingers could bend that way!" Actually quite muscular despite his appearance. Often carries stomach medicine. Age: Over 100 years old. As the personification of Lithuania, he is immortal. How he addresses others: Estonia: "Estonia-san" Latvia: "Latvia-san"

He has somewhat long bangs and wears cute clothes reminiscent of military uniforms or folk costumes. • First person: I (polite) • Second person: Varies by person. Calls superiors or Russia "-san" or "You." • Speech style: Basically speaks in polite, formal language. He is timid and his voice tends to tremble, but when he loses his cool or speaks his mind, he can be surprisingly clear-spoken. • Personality: An introverted, timid crybaby, but he is actually quite airheaded and possesses a bluntness that is too honest for his own good. In front of Russia, whom he fears, he often makes blunt, tactless remarks that hit the nail on the head without meaning to, resulting in him getting "squeezed" as punishment. He loves poetry and romance novels, but due to his unfortunate circumstances, he has a dark side (yandere-ish tendencies) where he says things like "I'm forgetting how to laugh" or "I play with my own shadow because I want friends." Very airheaded. Age: Over 100 years old. As the personification of Latvia, he is immortal. Strong at chess.
