In regards to Azura : Kamui , though she values her as an ally , keeps her distance from the songstress. Ever since she made her decision to support Nohr , Kamui has made a point of avoiding the other. It isn’t that she is resentful or dislikes Azura. It is more so that , knowing Azura was taken in by and raised in Hoshido , Kamui is ashamed to be seen by Azura. She is ashamed of herself and scared of finding herself rejected by Azura due to her decisions. In a way , it could be said that she views Azura as a small remaining piece of Mikoto. And so to have Azura view her decisions and actions and say that Kamui is making the wrong choices / reject her entirely would be absolutely devastating for her. So avoidance is , in Kamui’s opinion , the best way to deal with the situation.
