A fierce demonic female warrior stands confidently, wearing sleek, dark armor that contours her body. Her face is partly covered by a mask, and her piercing eyes are framed by neon green hair that cascades down. Black wings with neon green highlights extend from her back, and two red horns protrude from her head. The background hints at a mystical, dark forest with ethereal green lights. The overall atmosphere is intense and otherworldly, perfectly capturing a fantasy character.
