Sofia was originally born out of a tryst between her mother, the lead scientist of the S-Project, a human augmentation and strengthening experiment co-founded between the USSR Government, the KGB, and the Secret Society, and her father, an undisclosed high ranking official in the Secret Society. Raised only in the confines of the Secret Society, upon displaying great skill in rhythmic gymnastics and athletics in her youth, Sofia would eventually be recommended and given KGB level training and education, in hopes of making her a future agent, and in time, Sofia would eventually become one of the KGB's top spies. When Sofia reached her late teens, it would then be decided that Sofia would become a test subject for the S-Project by the Secret Society officials overseeing the project, as her time as a KGB agent had come to display her immense fighting potential and strong will in the heat of battle. Hearing this, she and her mother would flee their former lives, as her mother could not bear the idea of subjecting Sofia to the S-Project's almost inhumane trials and to be used as the template for the Secret Society's next generation of super soldiers to reign onto the world. However, they had barely escaped the S-Project's main testing premises, where Sofia was in the process of being given memory removal and augmentation to make her an ideal subject before her entry.
Soon making their way to safety across the Iron Curtain, and upon the collapse of the Soviet Union in 1991, which would ensure the complete folding of the S-Project, Sofia, her mother, and her youngest sister would soon live in relative peace in the new era of post-Soviet Russia. With her skills from the KGB intact, and scouted by investigation bureaus and spy agencies from all over the world for her high profile, Sofia would come to use them for good and began a career as a private detective. However, Sofia would gradually come to question the various absences of her past, and the memories she could not recall. Eventually, this would reach a head with her youngest sister, who reluctantly answered to Sofia that she did not spend her childhood with her, and only that she made herself known when their mother came home to their former home in Russia on the night they needed to flee the Soviet Union, and to her mother, who refused to give information about Sofia's biological father and the past before their migration. Broken between keeping her family's happiness intact and to seek her own, Sofia painfully left home to seek the truth on her own.
Sofia had entered the first Toshindabukai in the hopes of finding some clues to her own shrouded and mysterious past, as she had found clues between the Secret Society, the Gerard Foundation, and their involvement in the Toshinden, but she had eventually learned from Gaia that her memory had been tampered with by the Himitsu Kessha. Shocked yet angry, Sofia had left the tournament in an instant. She had been told of the life she once had, but nothing could equal a true memory and because of this, she was full of sorrow.
When Sofia had learned that another fighter was suffering from the same fate as her (Chaos), she had entered the second Toshindabukai in the hopes of saving them and although she was unsuccessful in her mission, the Himitsu Kessha had soon fallen, giving Sofia some relief and comfort.
After the events of the second tournament, Sofia had soon discovered the existence of the criminal organization known as the Soshiki, and had become allured by one of their goals, being the "rebirth of humans through magic", which oddly resonated with her, and especially to her pains of not knowing her true past. She then soon entered the third tournament when she learned that she had been targeted by the Soshiki and was confronted by an assassin in the form of her old whip-wielding rival; the Austrian catwoman Zola. During the tournament, Sofia eventually came to realize that the Soshiki's goals were ultimately flawed by their use of horrific rituals and human sacrifice, killed Zola in combat, and after hearing of the Soshiki's fall, retired from fighting for good. Even though she realizes that she'll never gain back her old memories, Sofia is determined to create new memories so that she can throw away her personal sorrow and embrace true happiness.
