Choosing not to resist Ryozan's frosty grip was a curious decision, but it was one that the kitsune intended to take full advantage of. Once he gripped Mr. Sunshine's wrist, his entire forearm became coated in a frost that made the previous blizzard strike seem like a cool summer breeze. Since he had chosen not to resist, he would feel the pain of frostbite immediately set in, his nerve endings would go numb, and his flesh would literally freeze. Nor would he be able to uncurl his fingers until the arm thawed and the damage was tended to, leaving his sword locked in a stiff and rigid arm. If Mr. Sunshine continued to allow Ryozan to pump his cryomantic ki into him, the frost would spread all the way up to his shoulder. 

Mr. Sunshine's two part attack was a much more practical decision. He had assessed correctly that Ryozan's Tanzo-ryu was one such style that focused on the upper body, and Ryozan was not blind to its weaknesses. Even focused as he was on delivering his strike, he saw Mr. Sunshine's foot wind up for the strike, and he knew there was very little he could do to prevent the blow from reaching its destination. Mr. Sunshine swung his foot in a beautiful arc and, just as he predicted, swept Ryozan's foot out from under him. Had Ryozan been a human, the attack would likely have gone just as Alexander wanted it to. However, he would see Ryozan's body tilt slightly to the left, and then stop, his balance readjusted. 

Instead of initiating a frantic retreat to avoid the sweep entirely, Ryozan decided to use what the the gods had blessed every member of his race with to counter its effects: his tail. As Mr. Sunshine's foot swung in for the attack, so did Ryozan's tail swing down, acting as a brace for him to shift his weight onto once he lost his left foot. It was only a temporary solution, and would not substitute for a leg, but it would give him the moment of balance he needed to get his foot back on the ground. Since he would not be falling, his grip on Mr. Sunshine's wrist would remain adamant. 

That left the matter of the punch emerging from behind Mr. Sunshine's back. Bringing a limb out from behind your back and immediately using it to attack is about as telegraphed as an attack could get, so Ryozan had a pretty good idea what to expect. As he brought his arm out, the structure of the gauntlet around Ryozan's right arm shifted from that of a blade to spiked knuckles. As Mr. Sunshine swung, so did Ryozan. The kitsune put all of his stone-smashing force into a punch that would meet his rival's fist in the air head-on. It was his ki-infused, spike-knuckled ice gauntlet, versus Mr. Sunshine's naked fist. Upon impact, Ryozan would also release the ki he had charged up in his arm to unleash his hasaiken, a ki attack of raw destructive force that would add an explosive impact to the collision. It was a strike that could shatter boulders; would Mr. Sunshine's bones be able to endure as the impact sent shock waves down his arm?
