Well it is technically possible, but I don't see it happening. Issei was a reincarnated devil who rose to the rank of high-class devil and got his own set of evil pieces. Ravel and Grayfia are pureblood high-class devils that decided not to get a set of evil pieces and form a peerage and decided to be in someone else's peerage. Comparing them to someone who is already a king becoming someone else's servant is ridiculous. I have no problem with her being one of his team members or being in Issei's harem. But it's really not necessary for her to be in Issei's peerage. That's just a demotion. Issei went from servant to king. Roygun would go from king to servant. See the difference? She's just banned from Rating Games temporarily and would have to work her way up without the king piece. Now she's powerful and strong, but she's already a king and I see no point in her becoming someone else's servant.

And isn't training low-class devils to become high-class and Ultimate-class the whole point of this series? That's what Rias and her servants have done. How do you think Issei got this strong in the first place? That's no different from the thinking of high-class devils who are just concerned with getting powerful servants and don't want to bother training them. Elmenheide is being trained right now. Sairaorg had no talent at all and got to where he is at now by hard work and training. You think everyone is going to be like Sirzechs and find a bunch of servants that are already really strong? I understand with the current situation going on and how strong they are at this point how important it is to have powerful servants. But by saying that you insult Issei and Sairaorg.

And where does it say that it's mandatory to get your own set of evil pieces when you get promoted to high-class devil? While getting your own set of evil pieces is the main benefit of becoming a high-class devil, not everyone would want that. Kiba said he wants to serve as Rias' knight forever(Well, I don't remember where it said that. I need to check). And Azazel said that Issei and Kiba would probably become Ultimate-class devils before Rias starts competing in the professional Rating Games. And Kiba has never expressed any desires to have a peerage. There would be other benefits to getting promoted to high-class devil like status. And Saji said he needed to get promoted to mid-class devil to get a teaching permit. So there would be similar benefits like that upon being promoted to high-class devils. Not all pureblood high-class devils want to get their own set of evil pieces and have their own peerage as we've seen with Ravel, Grayfia, and Kuisha. Why would it be even different for servants that are promoted to high-class devils? Sirzechs' servants are most likely high-class(more likely Ultimate-class devils) and I've seen no hint of them having their own peerages.

Now Roygun would be an awesome addition to Issei's harem. But it would just make more sense for her to become his retainer.
