serafall , she's fine being single , since I can't see her married to some guy without being able to put up with his whims xD. * and as some readers say it would be great if you take pity and add some girls with fluffy features(can be yasaka or just maybe gabriel , of course it would be later when there is the peace agreement , where before the main character meets gabriel hiding his devil status and when the "peace treaty" is made. You can make a marriage with gabriel to make the other party feel more secure (xD).
ummmm what do you think Serafall and Grabiel or Serafall and Yasaka since they seem to have an ambiguous relationship between them 2 in the novel and anime and they get along very well or as I said before Serafall and Grabiel since Grabiel has always wanted to be friends with Serafall after She went through the war and the civil war, something that is rare for an Angel of a status like her from there, you can get a very entertaining story for either of those 2, be it Grabiel or Yasaka or better yet, both
