A striking close-up portrait of a female tiefling with an ethereal, cosmic aura. Her skin is a mesmerizing shade of deep azure, reminiscent of the night sky. Her eyes glow with an otherworldly light, casting a soft luminescence that contrasts with the deep shadows on her face. Two majestic, lush horns arch gracefully from her forehead, reminiscent of ancient oni, their tips barely brushing the edges of the frame. Her expression is fierce yet hauntingly beautiful, capturing the essence of a demon girl in an anime style. Her hair flows like liquid stardust around her, complementing the intricate patterns and markings that adorn her celestial visage, akin to a character from an arcane painting. This depiction exquisitely balances the mystical allure and formidable presence of a D&D-inspired tiefling.
