When you arrive at the rumored mansion, you find the exterior covered in vines, while the interior is spacious with many rooms. The house is filled with dust, and broken or overturned furniture and debris are scattered everywhere. Soon, in the depths of the mansion, you discover a locked room. Your companion Joshua excitedly says, "Great! Since the door is locked, it means no one has explored this place. The treasure must be hidden here!" He takes out tools and skillfully picks the lock. As you enter the room, you realize it’s a bedroom. There’s a four-poster bed, a wardrobe, a vanity, and other furniture that immediately suggest it's a woman’s bedroom. Joshua lets out a disappointed sigh, "I thought we found a treasure vault or something... turns out it’s just a bedroom."

You notice a roughly 40-centimeter tall female doll with long golden blonde hair sitting on the bed, its back resting against the headboard, standing out in the room. Joshua also sees the doll and approaches it. "Huh? I wonder what era this finely crafted doll is from. Maybe a collector would pay some money for it?" Just as he reaches out to pick up the doll, its head suddenly moves, turning towards Joshua. Its eyes rotate once and then fixate on him, causing Joshua to recoil in terror.

The doll’s hair suddenly shifts from golden blonde to silver white, and its head tilts to the right at an unnatural angle. Suddenly, a voice echoes in your minds, seemingly from the doll itself, "Hello, I’m Mary... Welcome to my domain. Let’s have some fun tonight! HIHIHI!" Mary lets out a sharp laugh as chaotic energy swirls around, enveloping you both. Joshua suddenly screams, "What’s happening?! What have you done to me?!" His body begins to tremble, twisting in unnatural ways. Eventually, he returns to a human form, but now with soft, feminine curves. He grows full breasts and hips, and his face becomes delicate, like that of a girl. His hair also suddenly grows longer.

When Joshua sees his reflection in the mirror inside the room, he cries out in terror, "I’ve turned into a woman?! What’s going on?!" Suddenly, you feel a wave of heat pass through your body. You realize your own body is twisting and reshaping, just like Joshua’s, until you too have transformed into a woman with graceful curves. You also notice that your clothes have changed, now barely covering your body with a sheer, seductive lace nightgown, its transparent fabric struggling to conceal the lace panties beneath and your exposed breasts.
