The witch just stared - more or less, considering she didn't have an actual face - as he was sent flying backwards by that. There wasn't any surprise at him changing forms, but whether that was since she simply couldn't express it or since Kyouko had seen him doing it before was still up in the air. But then again, if this was Kyouko she would have been at the very least laughing happily and gloating (if she would have been sparring with him in the first place) rather than remaining there silent and motionless, almost cold and distant just by the exterior.

When she noticed him jumping at her, she was trying to dodge though, but-- the horse was just a little too slow in said dodge, so the sword put a tear into the witch's long traditional dress. It didn't seem to really hurt her though, or at least not enough to make any indication of pain show up. Instead the witch backed off a little, and it was almost as if she disappeared into the mist that was hanging heavily around the barrier.

But then the witch slowly popped up to Wolfmon's side in the mist - but if he would look there, she would already have disappeared and appeared by his right instead. And after that it was almost as if she was everywhere, as if he was surrounded by multiple versions of the witch, although the truth was that all but one of them were actually illusions. That power of Kyouko's that she had surpressed because it reminded her too much of the loss of her family, but.. the witch had no feelings, no qualms in using it.
