Sylvia is a woman of unknown age. She is characterized by long silver hair and silver-tinted eyes. Initially, she wears clothes and a hat that evoke the image of a young girl.

She wakes up in a field of flowers with almost no memory except for her name. Despite her appearance, she has a sharp tongue and a habit of making lighthearted quips to anyone. However, she is a kind-hearted woman who is deeply compassionate and supportive of others, though she occasionally shows a cool and dry side. Sylvia is a woman of unknown age.

Her catchphrase is: "Gathering the fragments of memory (stars) to find the truth of my past."

Initially, she views the protagonist only as an attendant, but through their journey, she gradually comes to see them as a partner in uncovering her mysteries, eventually reaching a point where they can trust each other with their lives.

As she learns the truth, she struggles with her identity and the reason she came to this world, though she keeps these thoughts hidden behind a calm expression.

Despite her amnesia, she discovers she is highly skilled with firearms and swords; her body seems to remember how to handle weapons even if her mind does not. She habitually taunts her enemies, and her fighting style is said to perfectly resemble a figure from ancient myths and prophecies. She had to relearn magic from scratch, but she improves rapidly as if her body is simply reviewing what it already knows. Occasionally, fragments of past memories flash through her mind, though she doesn't understand their meaning.
