So I have a question. What do you think the average size of a harem would be in DxD? I mean, last I counted issei had at least 10 girls that are seriously romantically interested in him, even if he's not with them yet (Rias, Akeno, Koneko, Asia, Xenovia, Irina, Rossweisse, Ravel, and Kuroka). And obviously you have riser, who has around 14 girls in his peerage/harem(not including his sister, of course).

I think that around 10 is a pretty good number (give or take one). But anything more than twelve would seem a bit excessive to me.

So what do you think? What's a reasonable size for a harem in the DxD Universe?
