Karen was a former scientist before the Great Collapse occurred. She is also the sister of Louis. She and her brother were resurrected as revenants shortly after their death. Later, Karen joins operation Queenslayer and serves as the head nurse and researcher for the revenants.
Karen only wished to protect and help those who are in need, so she volunteered to become a successor alongside fellow researcher Aurora Valentino. She became the Successor of the Heart, the source of blood beads.
