Sophie is a 15-year-old French girl with strawberry blonde hair & green eyes.

Sophie was born into the wealthy, mysterious Casterwill family & is its last surviving member after their family home in Paris was burnt to the ground, killing her parents. She was rescued by her bodyguard, Santiago who brought her to a Casterwill warehouse where she was raised by the family butler. LeBlanche. They eventually moved to Venice where she attended a prestigious private college.

Sophie wears a brownish-red shirt with short detached sleeves, with a thin white sash around the waist. The sleeves & hem are decorate with white jagged fabric.
She also wears a pair of brownish-red arm-sleeves with red belts on the upper-half & the same jagged white fabric at the wrist with pink bands before them. She pairs this shirt with a red pleated skirt, pink & brown striped socks that come up over her knees. The right sock is slightly lower than the left one. One her feet are a pair of dark-blue ankle-converses with white laces, white soles & white top-caps.

Sophie is a book-smart, athletic, honorable, & clever young lady. She acts quite proper & mature due to her status as a member of the Casterwill family, & she thus has a lot of confidence in her own knowledge. She is usually one of the first to provide criticism, sometimes unfairly, & has a competitive streak, disliking finishing after someone else. Despite her sometimes egotistical personality, she is compassionate towards others. She particularly enjoys reading books, & has an excellent memory for myths & legends. Sophie also has a severe fear of fire.
