I think that Roygun is the adult woman(if Ishi is not against that) with more chances to join Issei harem. She lost everything..

About Yasaka.. She is the Youkai leader and her daughter will be in Issei harem.. Her only chance is Ishi interested in add one mother/daughter in the harem(despite he added 2 sister, this will surprise me even more).. Yasaka and adult Kunou will be very similar(except the color hair)..

About the granfather words... Maybe Yasaka is more interested in give her daughter. I think that she only said joins him while he was waiting until her daughter was an adult..

I doubt see Ishi adding many adult women in his harem.. I think that in the end, Tiamat fans will be right.. Maybe 2 but I can´t see 3 adult women.. Less with Kunou that is the same that Yasaka.
