You can bet the house that Issei when LeFay becomes his magician Issei will ask her out on a date or he will put her into his Harem because remember to him age and race are not a big deal because to me Issei is just a younger version of Jiraiya but I admire Jiraiya's skills more than Issei because that guy can fight.
