Ice Release: Rasengan

The Ice Release: Rasengan is an original technique created by Kiiro Yuki, expanding on the original concept for the Rasengan: mixing one's chakra element with the Rasengan, emphasising the combination of the highest forms of Shape Transformation and Nature Transformation.

Usage
To create it, Kiiro gathers cool Ice chakra in his hand, which he then begins to swirl it rapidly as in the Rasengan. As the ball spins, the temperature of it decreases drastically, and tiny shards of ice form in it. As the ball is then thrust at an opponent, the cold chakra decompresses rapidly, lightly freezing them, and making their skin brittle and paper like. The small ice shards then rip apart frostbitten skin, and penetrate deep into the victim.

Triva
Using this technique, Kiiro can make the perfect Kakigōri, by artificially forming the snowball into a perfect consistency. At the same time the syrups are even mixed through, so the flavor is the same throughout the treat.
