i dont know 40 maybe im not sure, anyone who's read shin volume 2 knows all of the confirmed members of the harem rias, akeno, koneko, kuroka, le fay, rossweise, yasaka, kunou, roygun, ingvild, elmenhilde, ravel, asia, xenovia, irina. But in his dream rias reveals to issei that there are still many more brides and thats what makes me think he gets more than 30 but even an estimation of how many he gets is tough

i mean i could be wrong and im open to anyone else's guess but him having hundreds or thousands seems to me to more than likely to happen in the not to distant future
