A terrifying Manananggal, a female monster with a grotesque half-body and large, leathery bat wings, soars menacingly near the edge of a shadowy rooftop. Her sharp fangs glisten in the eerie glow of a full moon that casts ghostly shadows across the night, creating a chilling contrast against the dark skies. This scene captures the essence of horror and folklore with a hyperrealistic, photorealistic 8k rendering, using advanced 3D rendering techniques for a nightmarish sense of realism. The setting is steeped in the macabre themes of Philippine folklore, with an unsettling, expressive style that heightens the haunting atmosphere, blending traditional horror with a modern, unreal engine aesthetic.
