Instead of his weapon combo going off without a hitch, it instead met with quite a speedbump. Unplanned for, but not unexpected. Something that would be dealt with as it came, rather than with a planned out motion. He realized that his opponent was planning several steps ahead as well, leaving this as a moot game of chess. A stalemate is never a pleasant way to end a chess match. Shin preferred Go anyway. 

So too did he prefer being oblivious to the thought process of his opponent, there were few things that he genuinely hated in this world. Cowards who didn't accept death as it came, LeeRoy for obvious reasons, and the Japanese. Why the Japanese? They invaded his country, they killed his people, and ended his bloodline. Among other crimes. To find that she was pulling a page from a Japanese warrior's book would be more than enough to make Shin take this fight personally. 

His weapon had no trouble enveloping the first projectile, obviously it was as amorphous as the object it was seeking to capture. The result was the same with the capture and release of that spell away from himself, obviously pointing upwards rather than backwards this time around. Though this was moot since there was a secondary projectile that somehow had gone entirely beneath his notice, his eye wasn't perfect and could only focus on so many things at once. Flaws made a man stronger so it wasn't an issue, but what WAS an issue was the fact that his right hand was suddenly entrapped within a bubble of crystalline air. With the explosive results of the previous spell, Shin had no intention of letting his hand remain entrapped. 

With his right hand trapped inside of her crystalline cage, and an attack on the way he had quite a few options to work with. Along with several different orders of importance, depending on which was more pressing. Deciding first that the oncoming attack was more important, Shin turned his waist away from the oncoming slash and pushed himself back. Planting the butt of his staff in the ground and using its weight to slide backwards and around, putting the staff between his body and the polearm again. The fusion weapon would collide with his staff at about the midriff, just above his right hand. It would not strike blade first, it would strike it with the pole instead. The tip of the blade would be pointing just past Shin's shoulders and the flat would be somewhere parallel to the ground. 

While all of this was going on, Shin had been busy subconsciously. Remember those wires that Shin had wrapped around his right hand right at the beginning? Those began expanding explosively in a triangular pattern. Shoving the crystalized air away from his hand with force. Now, the positioning of Shin's hand and the pole of Corban's polearm was important here. Why? Because that crystal cage had suddenly become a crystal projectile again, firing straight upwards towards the handle of her staff. 

This would have one of two results, either it would break the handle or would cause it to be pushed upwards in much the same way as his own weapon previously. Either one would disarm her momentarily.
