She's best known for her glamorous casino—which, ironically, she's legally barred from entering herself. Instead, she channels her energy into tourism, interior design, and cosmetics, fields where she's found real success. Despite the restriction, she's a confident gambler who doesn't shy away from high stakes; she famously bet a date with Seborga on a poker game and showed real faith in their schemes, like the Halloween plan to recruit allies.
Her official profile paints her as a prideful, stylish girl with surprisingly old-fashioned speech patterns and genuine intelligence that's kept her nation thriving. She comes across as stern and prone to worry—constantly thinking about world affairs and economics while staring at the sky—but she's actually quite calm and sociable once you talk to her. Her main anxiety is other countries' rowdiness. At heart, she's an optimist and a dedicated honor student who does ballet on the side. She believes in the power of clever behavior and famously refuses to eat tuna.
When Hidekaz Himaruya was developing her character in 2008, he wanted her to feel "way more than healthy/energetic" but also "leisurely optimistic" with a refined quality to balance things out. She owns a Japanese-style garden not far from her casino, adding another layer to her carefully curated world.
