She was a human (soul) used in place of one, hence why she's referred to as the false demon/sin. The Demon of Sloth never existed to begin with, though the Gift novel's narrator is quick to admit that she might actually be the real Demon of Sloth in effect rather than technicality.

Elluka's essentially entrapped Eve in her body, and that's allowed her to draw upon her memories and powers. The side effects are her more rapidly decaying connection to her human body.
