Aigis v Yukari seems pretty bad for Yukari. My friend plays Aigis, and I typically don't have much breathing room to set anything up. One thing though is that you can typically control how Aigis approaches you and stop air approaches with 2D, 2B, or a bomb. Also it seems like a good idea to just try and make her waste orgia meter instead of trying to be full on aggressive. Aigis' persona is annoying in this matchup since she can put out the counter to stop you from using arrows too much. Aigis' bullet moves beat Yukari's normal arrows and her special arrow is pretty bad in general so using it here wouldn't be a good idea.
