Iron Wind King

The Iron Wind King is a nintaijutsu aura technique developed by Kotarō. To use it, Kotarō crosses his swords behind his back, forming a cross shape. Then, as he flows chakra through the blades, a hollow cross shape forms behind him. It is unknown what properties this cross has, besides signifying that the jutsu is active. The jutsu manipulates the air around Kotarō, reducing friction and greatly increasing his speed.

Effects
When in this aura, Kotarō's speed and Wind Release ninjutsu are increased exponentially. He becomes fast enough to disappear and reappear behind a target, although he admits Shio's reflexes are fast enough to negate this. Also, his wind chakra, channeled through his blades, may be used as a ranged attack in the Wind Truth.
