I believe it's pretty much confirmed that there aren't going to be grown women in his harem or peerage.

Bennia is Sona's knight and she doesn't have much of a connection with him besides being in the same club.

I just don't see Verrine in Issei's harem or peerage.

I really don't see Le Fay or Elmenhilde joining his peerage.

I can potentially see Kunou in there but she's still the future leader of the West Japanese Youkai. Ishibumi could change it.
