No... No idea.. But one of them(or maybe 2) should be one Shin dxd character that doesn´t appeared yet.

They should be important characters in other countries/mythologies... Bryndhir was Rose daughter name in EX too... I don´t see another valkyrie.

About Roygun, even if she is MAYBE the EX Belephor Maou(most probaby option)  but she lives in the underworld, she can´t be a Local Wife.

'''Maybe Issei will add 2 local wifes of another Mythologies... Ingvild can be one excuse for know more about Greek Mythology(she needs Hypnos and Morfeus) and maybe recruit one female of that Mythology..'''
