Egged on by her friend, Himari, our main character, performs a ritual to summon a ghost.

...Well, kind of. It was a little half-assed. But then, the doll she used in the ritual actually starts moving! Himari sees her life flash before her eyes, but then, a ghost appears.

"I just happened to be passing by, and I couldn't just leave you to die!"

But wait... Something's off about him... She notices some of his black aura on the doll.

"What better way to thank me for saving your life than giving me a little of your life force?"
"No. That's what you wanted all along. You're the one who was moving that doll."

Himari sees right through the ghost's lie... But that only gets him excited, and he begins to have his way with her. Himari fights back every step of the way only inciting his passion further.

"Are you doing that on purpose? That's only going to make me get even rougher! Y'know, I'm gonna make you my bride!"

Himari continues to resist, but...

"This is what you really want, isn't it? To be caught, pushed down, and made to climax again and again... To be dominated by a powerful man."
