Bad at recapping back story

so I have been reading a lot of novels, and uh I found one which i certainly found hilarious. About a villain protag just don't to mess with the original "hero" of the story, but some reason the heroine can listen to the villain protag's thoughts. I think it is an interesting concept. I also have been reading lots of DXD lately. And I have to try it out. disclaimer I do not own any of the photos in this fan fiction, nor own highschool DXD nor monster hunter. (IF I did I would be rich)
