A dark fantasy anime-style digital illustration of an extremely beautiful black demon woman with white hair and red eyes, wearing a kimono and holding a sword in her hand. She has horns on her head, and the scene is set at night, surrounded by sakura flowers and cherry tree branches. The ground is covered in smoke or fog. It is a full-body shot from the side, with dramatic and cinematic lighting, giving it a concept art feel. --ar 9:16 --niji 6
