My favorite girl for Issei to pair up would be eiher Serafall and Rossweisse, and I have a soft spot for both of these ladies, and I don't care about Serafall habits of cosplay at all because it is rather cute, and it is hard to believe that Sona and Serafall are related because they are as different as Night and Day to each other.
