Pink-Haired Girl Posing with Undead Monster in Library

A seductive pink-haired anime girl with pale skin sits on a wooden desk in a dark library, wearing a tight black lace bodysuit that accentuates her curves. She poses confidently with one hand near her face, looking back at the viewer. Behind her looms a terrifying undead monster with glowing blue eyes, exposed skull, and decaying body emitting blue smoke, creating a dark, erotic horror-fantasy atmosphere.
