I agree with Gary on one aspect Ravel will be a tough blow to handle because she is defintely part of the Harem, and if the Author did say that the girls will have a happy ending killing Ravel makes no sense in my opinion because I don't want for the Author to start doing what they do normally in Akame, which is to kill off important characters like flies because it will anger the fans because it is expected for that series but Dxd is entirely different.

I am sorry for the question about Ravel but the Author left a massive cliffhanger that won't be known until Volume 21 because Volume 20 is all about Vali so I don't think they will talk about Ravel in that Volume.

I do agree that she can't die if she is a part of the Harem because it contradicts what the Author said about the girls getting a happy ending with Issei because there is no happy ending if you are dead you know.
