She is not human, and she doesn't know what she is. To be honest, her gender is not necessarily female. She ate a dead woman, so she replaced everything about her.
She is used to human life, but this does not mean that she is a human. After she eats the flesh of a creature, she can obtain the genes of that creature and can transform into the creature she eats. The more she eats, the more creatures she can change, as long as she wants.
Intention: Anyone with ideals is great
