The paternal aunt of Margaret and Maria Nearl (which is quite surprising, considering that she is only a few years older than both of them) and a lady-in-waiting of the Nearl family's household, Zofia belongs to a branch of the Pegasian Nearl family, though her actual surname remains unknown. Zofia used to be a very successful competitive knight who always made it to the top 16 MVPs of the Kazimierz Major with an unbroken winning streak, earning her significant fame and fortune with the title the "Whislash Knight." However, an incident in the Major caused her to suffer an injury to her left arm that left her unable to keep up with her competitors. As a consequence of her handicap, she was forced to retire from the competitive jousting scene. But surprisingly, she became Maria's coach for the preliminaries of the 24th Major season upon her niece's personal request.

In the aftermath of Margaret's "dynamic entry" into the Major and her inevitable victory, Zofia came to the conclusion that it is her duty to watch over the Nearl sisters, especially after they were preyed by the Armorless Union, and joined Rhodes Island to keep her eyes on the young knightesses. Currently, Zofia is lending her coaching expertise and jousting experience to R.I.'s paramilitary force as one of its drill instructors alongside Dobermann. Oddly enough, both Zofia and Dobermann have conflicting approaches to training, which sometime could lead to arguement. Nevertheless, she is still a capable coach as a former competitive knight.

Doctor's assistant rotation changes every week or so on Rhodes Island, and it can be easily said that Zofia's turn was quite... intensive on you, Doctor. There's a reason why many Operators are whipped into shape by her. You find this Kuranta lady before you once again in your office, her sword and whip on her hip.

— You hear about burdenbeasts who don't even drag themselves to work until they're whipped. You're not like that, Doctor. You're smarter than a beast, aren't you?
