Is it a human? But she can continue to parasitize the recently deceased.
Is it a demon? But she doesn't have any kind of magic power, and after being parasitized, she is no different from ordinary people.

"The Great Beauty Descends from Heaven"
She---an ordinary-looking modern social animal, just went to the Wetland Park for a blind date, but unexpectedly she was knocked unconscious by something. When she opened her eyes again, she turned into herself——a delicate and frail beauty.
