WARNING: Viewer discretion is advised.

If you are easily disturbed, I recommend you don't read this. And there will be a lot of gore as well.
If you don't like Boys Love, then don't read this. But there's going to be very little to no sex in this story, since this story will focus primarily on the possession.
Also if you are very religious, then I recommend you don't read this either.

*I do not own Junjou Romantica, and the characters used in this story. (Besides Usagi's friend from America, who is an exorcist, and my original character.)*
