Garota demônio descansando sob um único poste de luz em um beco

Create a semi-realistic anime demon girl with an elegant and mysterious appearance. She has long white hair that gradually fades into deep purple at the tips, giving it a soft ombré effect. Her eyes are heterochromatic: one eye glows bright purple and the other glows crimson red. Avoid the usual red-and-black demon design. Instead, dress her in an original outfit dominated by white and violet tones, with subtle dark accents and intricate details that make her look supernatural yet refined. She has a slender demon tail visible behind her. The scene takes place at night in a narrow urban alleyway. She is leaning against a wall in a relaxed, slightly tired pose, as if she is hiding from the world or quietly observing the night. The alley is mostly dark and illuminated by a single flickering street lamp above her. The dim light softly outlines her figure while allowing her glowing eyes to stand out dramatically. Her white-and-purple hair catches a faint glow, making the tips shimmer in the darkness. The atmosphere is cinematic, moody, and mysterious, with subtle fog, scattered rain puddles reflecting the light, and a quiet sense of loneliness.
