Actually looking at DXD, it's quite problematic when you compare the peerages. Riser, while he might seem disgusting, has a peerage that is united and supportive of each other, willing to fight for each other. Rias' peerage, at that stage, the neet vampire won't come out of the closet for her, the catgirl and the half-angel both won't face their pasts for her, everyone's so half-hearted...
