As he got jerked forwards, Cunkuu managed to see the attack coming, this time at least. The spectacular speed would still be a problem, but he just visualized the protective Dome on his face, completely mitigating any attack that could be leveled at his most vulnerable point. The three inch diameter circle of dancing lightning appeared instantaneously, and it would either simply repel Shin's attack or make his fingers refuse to move for a long time, as a result of the electrical charge disturbing the nervous system of his adversary.

 A lesson, Cunkuu would have snorted, but he was too preoccupied with dealing with the enemy. Even though his left hand was still wrapped around his sword, and was not lifted anywhere high enough to perform an appropriate action as a counter attack, he could make use of the ridiculously out of control spell which had flopped, due to the unexpected attack coming in by the older man. 

 Although his hand was somewhere underneath his belt, it was still in a position allowing him to perform a cheeky attack, which, if successful, would deal incredible damage, potentially removing one limb from the fight, and maybe from the temple. His index finger popped up, and, using the heated air around them, he generated a Laguna blaze. It was a weak one, it wouldn't outright kill Shin, but it would be capable of dismemberment. At least it would really shock his adversary. The piercing lightning would, most likely, end up striking Shin's right leg, in the quadriceps femoris.
