A duel monster from Yu-Gi-Oh!.
This is Fleurdelis after Ecclesia separates from Blazing Cartesia the Virtuous, causing her to be freed from the "hole", albeit with a corrupted apparance. She wears a breastplate, greaves, and wields a greatsword. Her left arm is significantly swollen and corrupted as a result of her initial death and absorbtion by the "hole".
