Description
Representing the Kingdom of Sweden, this human goes by the name Berwald Oxenstierna. His origins trace back to the Viking era, a time when he earned formidable titles such as "The Lion of Northern Europe," "The Conqueror of the Baltic Sea," and "The Supreme Ruler of Scandinavia" through military expansion. Historical records recount his combat prowess, notably defeating seven countries single-handedly with Finland as his sole ally during conflicts involving Lithuania and Poland. In the modern era, he adopted military neutrality, shifting focus towards welfare systems and peaceful endeavors.

Standing between 181-184 cm tall, he is the tallest of the Nordic nations. He possesses light blond hair and blue-green or turquoise eyes, though early anime versions depicted him with brown hair and dark brown eyes before aligning with the manga's blond-haired, blue-eyed design. His facial structure, stern like Germany's, features thin glasses. His signature outfit is a dark blue 1920s naval uniform comprising an overcoat, hat, black shirt, tie, pants, and boots, often complemented by a Nordic Cross necklace. Described as quite muscular, his imposing build frequently causes others to misinterpret his expressions as angry or threatening.

He maintains a silent, reserved demeanor attributed to his cold-climate origins, communicating primarily through grunts and truncated words reflecting a middle-Fukushima dialect. Strong emotions simmer internally but rarely surface outwardly. He embarrasses easily, increasing his shyness and making verbalization difficult. Despite his stern image, a playful side exists but seldom emerges due to others' reactions to his intimidating presence. He shows particular interest in debates and arguments, though participation is limited. His hobbies encompass furniture making, glass crafts, sewing, and artisanal skills like clothing alteration for Finland, accommodating their significant height difference. He produces fermented surströmming, noted for its potent smell and described as usable as a weapon.

Relationships are significant. He and Finland escaped Danish rule together, establishing a shared household that led Sweden to refer to Finland as his "wife," despite Finland's consistent denials. Finland uses the nickname "Su-san" for Sweden and harbors complex feelings mixing affection with residual unease; modern interactions show decreased fear and increased mutual respect. Sweden considers Finland a good friend.

He adopted Sealand after winning an online auction as the sole bidder. Their relationship involves Sweden attempting paternal engagement, like creating the "Dambolis" device to limit screen time, though Sealand often prioritizes independent interests. Sealand refers to him as "papa." Ladonia, residing on Swedish territory, behaves spoiled towards him, including tackling him during tantrums. Sweden humors Ladonia by role-playing defeat scenarios to alleviate the micronation's anxieties.

His historical rivalry with Denmark involved frequent conflicts following Sweden's rebellion against Danish rule. Modernly, they interact as friends, with Denmark expressing concern for Sweden's well-being and admiration for his lifestyle. Sweden shares partial custody of Estonia and Latvia with Poland, secured after initial confrontations where Estonia found Sweden's glare terrifying. Prussia exhibits extreme fear of Sweden, fainting repeatedly during encounters due to traumatic memories of the Great Northern War.

In *World☆Stars*, he appears in Nordic group activities and narrative arcs, maintaining consistent characterization. His design aligns with the manga's visual standards, featuring blond hair and turquoise eyes. The anime adapts manga chapters involving the Nordics.
