Title:
Toaru Jukujo no Hentai Choukyou ~Oite nao Shitataru Himitsu to Etsuraku~
Description:
The place where I once was. 
The scene I once saw. 
Some mansion. 
Exciting scene in front of my eyes. 
I could not understand at the time, but she violently crashed into my brain. 
White skin, illuminated by a dim light. 
Hanging a naked body, tied with a rope around the sections. 
And, after a few weeks. 
I suddenly left this city. 
I did not have time to understand what had happened, I closed the memory window and became drunk with the wave of a new life. 
After more than ten years. 
I came to this mansion again. 
The sobbing voice of a woman. A muffled voice is heard from the back of the mansion. 
Strange deja vu seized my consciousness. 
This feeling, once ... somewhere in my memory, this feeling remained.
