depends on how you want to quantify love. For example, Akeno immensely loves Issei, to an almost unnatural degree because she would lose all her will if anything had happened to him. All the other girls dont really go to this extent, well maybe Rias and Asia from what was seen in Vol 12 after Issei died, they all also extremely love him, though if i had to say who the least is maybe probably Xenovia because she doesnt seem to be the girl who gets all flustered by things like relationships and the like.
