 * sigh* Again, as said by B214, you're asking for nonexistent information, something that you are constantly doing...when you're not asking for information that you generally could check the wiki for if you can't recall from reading the story, hence why we're all so often annoyed with you.

But, as suggested by anon1, it is entirely possible (and most likely in Issei's case) for a male to choose to "marry into" his wife's family, thus taking their surname instead of the other way around. This was a real world practice, usually carried out by noble and other noteworthy families in order to continue their name when they had no male heir. In fact, that seems to have been the plan with Rias and Riser's arranged marriage -- he was a third son, and thus not the heir of the Phoenix clan, so they were marrying him into another family.... (yeah, Riser was a "noble", but the its the idea that counts). There are also similar real world practices of adopting a male heir into the family when they have no natural-born heir. The question is whether any of those prideful and condescending Devil nobles would being willing to adopt a "servant" into their family, they are all about "blood purity"...
