So as it currently stands, not only does Issei has 6 fiances, but also 7 mistresses Kuroka, Le Fey, Kunou, Elmenhilde, Ravel, Rossweisse and now Roygun.

4 who have shown interests in him: Tsubasa, Bennia, Kiyome and Mira. And 5 that you guys have mentioned to be potential harem members: lint, Seekvaria, Mirana, Tiamat and Lilitifa. let me know if I'm missing anyone out (excluding Serafall, Yasaka and Gabriel cause that's too far fetch).
