User blog comment:Lias' Pawn/Issei's possible further Harem members/@comment-25935458-20150111152722

I don't think Yasaka, Serafall, or Gabriel would fit in the harem (see other peoples comments - no need to repeat). I don't know about Seekvaria (I don't read spoilers) since I haven't read enough about her. There are several girls that would fit (near enough to Issei's age and not taken - that we know). But I think that Ishibumi, if he decides to increase the harem size, will due it in an unexpected way. My hope is that who ever it may be will stir things up in a unique way. My vote is for an emissary of Chichigami to appear - wouldn't that be a shocker for everyone!
