Yay for a Volume 17 thread at last!
Kuroka and Le Fay are pretty close to joining Ise's harem, but how many after them will join is another matter. Regarding Rose, I still think that being Ise's second girlfriend puts her higher up, like above Xenovia and Irina for #5, so it'll be interesting to see if the harem order changes due to v17. That would make for a pretty funny scene, Rias trying to organize the order of her fiance's harem based on how close he is to each of the girls
