@15sok, one word: friendship. Rias and Akeno's friendship is also at a completely different level than most, you can say that Rias and Akeno's feelings towards each other are similar level to the feelings they have for Issei. You can see them bicker over small issues and all but they still caring for each other sincerely. I think it's save to say that either Rias and Akeno might just suffer as much as they did like when Issei died.

@Otaku, can you just stop on the random rambling. What does the series being a harem series has to do with the question. 15sok was asking why Rias and Akeno's relationshop isn't affected, don't just simply interject your comments without thinking first.
