Well who doesn't love the appeal of an older woman? But still I'm not saying she'll be competition or compete with the main girls in Issei's harem, just that she'll fall in love with Issei. She's an angel and a Great Seraph after all who carries herself with dignity. And I don't remember any fanservice with Serafall or Yasaka in DxD.

Women that can be in Issei's harem:


 * Women that are unmarried, never been with a man, doesn't have any affections toward another male character, doesn't have children.


 * Have to be part of the supernatural world in some way. Actually part of it, not just knowing about it like Kiryuu.


 * Have to be beautiful or cute


 * Large breats(now or later. Some have yet to mature like Koneko, Kunou, and Le Fay)

And this doesn't mean that all females that fit into these categories will be in Issei's harem. Just saying those are the criteria for being in Issei's harem. For example, there is no possible way of me seeing Griselda in Issei's harem. Neither do I see Sona. Now Gabriel and Serafall, I still hope for. I'm just hoping and it's most likely very improbable. But I'm not asking for them to join Issei's harem now and compete with the other girls, but just for them to fall in love with Issei. But because of the barrier Serafall is very improbable. Again that's just my speculations and what I would want to see. If it doesn't happen, alright. But then again, no one expected Issei to be promoted to a high-class devil in less than a year after being reincarnated. Two different cases, sure. But we will never know what curveballs Ishibumi will throw our way. Elmenheide falling for Issei, Roygun pledging allegiance to Issei, etc. Ishibumi has never failed to surprise. While some things. So that's just how I feel.
