Edelgard, Fire Emblem Three Houses

A woman dressed in a costume inspired by the character Edelgard from Fire Emblem: Three Houses. She is standing on a staircase, wearing a black top with red accents and a white collar, paired with red pants and black boots. Her long blonde hair cascades down her back, and she holds a large axe in front of her. The background features a tan wall with a window and a door to the right, while the floor is made of dark wood. The overall atmosphere suggests that the woman is attending a costume party or convention, possibly as part of a Fire Emblem-themed event.
