Sonia Nevermind

Sonia is a cheerful and polite girl with a great interest in Japanese culture. Being a princess, she takes a great interest in many rather ordinary things as well, such as cleaning and even the Japanese restrooms, due to not being familiar with them. She firmly wishes to be treated like a normal Japanese high school girl and her big goal is to have friends of her own age and status. Due to being a foreigner, she occasionally messes up figures of speech and has a tendency to use very outdated slang in an attempt to socialize with her fellow students.

Sonia is very kind and thoughtful, and she cares deeply for her friends, being very protective to those she holds a deep connection to. She can also be rather physically affectionate towards her friends, and her very polite personality is well-demonstrated by the way she is shown to be kind and polite even towards other people, despite not really liking some of them. While she is very friendly, Sonia's commands are rather assertive and captivate the undivided attention of everyone surrounding her. It is stated that whenever she commands people, they feel an instinctive need to bow and listen to her. However, she can also suddenly curse a lot and shout out loud whenever she is very upset or in deep distress.

Because of her upbringing, Sonia can be rather naïve and her general behavior can make her appear a bit ditzy at times, but she is actually smart and capable of complex political analysis, and reveals that she has faced many dangerous and stressful situations due to her status as a princess, and she is even skilled and fearless in combat. As a representative and authority figure of her country, she feels she has a great responsibility and always tries to stay calm and not show any weakness. However, she sometimes allows her ordinary self to be shown as she admits that she is desperate to go home to her people while breaking down in tears. She firmly states that she does not fear death, but she also won't let herself be killed nor kill any of her friends. She has a rather pragmatic side. Although she still tries to help as much as she could, her despising the fact that she has to "doubt" her friends usually becomes a priority, implying that she is very loyal to those she genuinely cares for. In general, she is shown to be deeply loyal to her country and always prioritizes her people and country over herself, even if it makes her unhappy inside.
