@B214

My words were "Barely know", "accept", "approval" so I'm not saying that Rias didn't have a research on Raiser's Peerage, she didn't accept Raiser using his harem or having his peerage as the mistresses, in vol 14 when Azazel asked Rias if she allowed Issei to have a harem she agreed to it because she loved him, it was different back there since Rias didn't love Raiser. So when she saw Raiser kissing his harem the feeling of disrespect and disapproval is stronger than a normal thing, because at that time Rias knew she would be married Raiser.
