Synopsis
When I woke up, the world was pitch black. The only thing I knew was that I was detained.

When I finally got used to it, I found a standing girl with arms folded in front of me. She calls herself Masaki Ujizaki, and she seems to be planning something, and to put it briefly, she wanted a dense play in a closed room. "Pu, what is Prei !?"

"That's not it!"

"No, I'm tied up and take off your skirt and expose your lower body."

"Hey idiot, hey, absurd ... !! "

When will I get out of here?
