Sonia is a tall, young woman with fair skin and pale sea blue eyes. She has knee-length light blonde hair, part of it styled in a braided crown, the rest left to flow slightly towards the left. Her hair is accessorized with a green-black ribbon flecked with diamonds. She wears a dark teal dress with a white collar, puffed sleeves, and belt. She also sports a large red ribbon with a blue jewel trimmed with silver on the chest. As well as this, she wears a pale bracelet on her left wrist, black over-knee socks trimmed with gray lines, and red toe cap heeled Mary Janes. Sonia is a cheerful and polite girl with a great interest in Japanese culture. Being a princess of a small European kingdom called "Novoselic", she takes a great interest in many rather ordinary things, 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 Due to being a foreigner, she occasionally messes up figures of speech and has a tendency to use very outdated slang in an attempt to socialize with her fellow students. Furthermore, Sonia is fascinated with serial killers and the occult and has actually stated that she likes Friday the 13th, which makes some other students a bit creeped out. She is very interested in visiting Hell when people talk about it, and in general, she is shown to be very in tune with his dark and bizarre ramblings, seemingly being the only one who understands Gundham Tanaka's way of speaking. 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. Her very polite personality is well-demonstrated by the way she is shown to be kind and polite even towards people she does not like. However, she does possess a more hostile side towards Kazuichi Soda, The Ultimate Mechanic, due to his somewhat stalker-like behavior (which, in this alternate universe, she is free of due to him going to a different part of the academy then her). 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, Sonia 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. She has a rather pragmatic side. 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. Ultimate Princess.
