Well, let's see. I've read over her profile and honestly really like her!
She and Yukina are both alike in the way that they don't trust people easily, and they've had experience with betrayal and treachery.
I'm sure they could bond over that, I really think so.
As for how they meet and bond, let's see now...
I was thinking of having Yukina roam the grounds and enjoy the place. They could meet, perhaps, in the park? Then learn of the fact that they're both at the same school, he could escort her to the banquet(when it occurs?)
I'd post with him at the front gate real quick, and at his dorm, and then he could head off to the park until the banquet.
