Ice Release: Sub-Zero Rasengan

The Ice Release: Sub-Zero Rasengan is the Ice Release counterpart to the Fire Release: Red Flame Rasengan.

Overview
The Sub-Zero Rasengan was invented by Kazuto Ryūken sometime during his training at the Yaseiki Tundra. Following the same methods for his Red Flame Rasengan, Kazuto applies ice-natured chakra instead of fire-natured chakra while forming the Sub-Zero Rasengan. Once formed, freezing blizzard-like winds swirl around the central Rasengan core. These winds are especially cold, as they are able to freeze anything within the user's environment.

After travelling a certain distance or colliding with a target, the central sphere of the Sub-Zero Rasengan detonates, producing a blizzard-like vortex in the immediate area. Within this vortex, the enemy is caught in a maelstrom of freezing temperatures, greatly damage them.
