yea i highly doubt it as well at this point, i mean its been 12 or 13 volumes since the Riser arc and there has been no one else to go after Rias, so to put one in now would seem kind weird, especially with how much Rias is in love with Issei and how they are basically engaged now. If it was before the engagement rituals maybe it would have worked fine storywise but at this point it'd seem tacked on and there'd be no way Rias would fall for another person now
