I am putting a bet that in Volume 17 Rossweisse officially joins Issei's Harem because I have a feeling that something will happen that will force this but I wonder if Issei will accept her as a new member but knowing him he won't reject her since he said that her Oppai rivals both Akeno and Rias, and for Issei that is a high recommendation because he ranks her in the top three. I know that my statement is speculation but I have a strong hunch about this something tells me that something incredible will happen that Rossweisse and Issei will hook up but I might be wrong about this.
