You basically can't, but this is the counterplay you should try for in order:
A) avoid it, and get into a position where you can punish it.
B) shield it, and then grab, unless you're facing away, then C) might be better.
C) crouch cancel it - this loses to a rando rest, or a grab; cc is great but don't get predictable with it. When you're ccing, you're a sitting duck.
D) ASDI down - during the endlag of a move, hold down as though you're ccing (this can be done with either analog or c stick). this can also be done during dash with c stick down.
E) DI and SDI to make it harder on the puff, I would say out and away from her is the best.
Hope this helps
