You know, the easier and more straightforward answer is to assume is that this girl is Yang's friend. -_-"

Also, Yang may be searching for this girl entirely on her own accord and not because of any official business and such. We already know that she can be a little impulsive, and she definitely doesn't mind thrashing things up a little. We can also see that she might be angry prior to Yellow Trailer events even though she entered the night club all smiles and sunshine. Why not assume that this girl, whoever she might be, was someone very important to Yang?
