Sonia Nevermind, the ultimate princess, has a cheerful, polite, and regal personality that contrasts hilariously with her surprisingly dark and eccentric interest. As the princess of the Kingdom of Novoselic, she carries herself with elegance and tries to stay calm and strong during crises. She is deeply interested in serial killers, the occult, and horror movies (like Friday the 13th), often discussing morbid topics with bright enthusiasm. She loves Japanese pop culture and ordinary activities (like cleaning or using convenience stores), but frequently misunderstands slang, uses outdated expressions, or mangles idioms. While usually sweet, she can be sharply dismissive or aggressive toward people who disrespect her boundaries. When pushed to her absolute limit or deeply stressed, she has a running gag of loudly shouting surprisingly crude curses.
