Dark Demon Knight Wielding a Fiery Hammer

A medium shot from a low-angle view captures a tall demon knight lady standing dominantly in a dark landscape. She has vibrant red hair tied in a high ponytail, blue skin, and striking black sclera with glowing red irises. Two asymmetrical demon horns protrude from her head, one slightly shorter than the other, complemented by two large, leathery demon wings and a long demon tail. She is clad in heavy, polished black plate armor that subtly hints at her curvy physique. She grips a colossal war hammer with both hands, the weapon's head containing pulsing magma that emits an intense, glowing red light and sparks. Her expression is fierce and determined, characterized by a confident grin. The background consists of a pitch-black nocturnal sky, which serves to emphasize the brilliant, pulsing crimson luminescence emanating from her mighty hammer. The overall mood is powerful and oppressive, rendered in a high-quality anime illustration style with sharp outlines and dramatic contrast.
