Kyōfūban

Kyōfūban (強風盤, Gale Release) is a technique associated with the Niten style of Zanjutsu which is not taught to aspiring students of the Yuengiri Academy, which is restricted solely to the style's four creators.

Description
One of the "taboo" techniques of the Niten. At any moment a practitioner can 'tame' the wind, bring it into line and subject that force to their whim by literally becoming one with it. Kenji explains that the lacerating winds are taken into the body. So far only Kenji has demonstrated successful use of the technique -- he is even believed to be the only one capable of performing it, in part due to his almost unnatural durability and endurance, and in part to his life force, which is twice that of normal. By taking the wind into your own body Maki explains that it will eventually succumb, resulting in excessive inner bleeding and possible death. With its use Kenji demonstrates the following:


 * the ability to become wind and move at excessive speeds and then reform himself to initiate an attack.


 * the ability to become intangible to avoid attacks. He can also become intangible mid-swing and then become perfectly tangible in order to lodge his blade within his enemies body for an easy kill.


 * the ability to control the wind surrounding him. With it he can hone it to a razor sharpness, direct it to lacerate a target, create powerful hurricanes and also as a means of protection.

The drawbacks, however, are quite noticeable even for someone with Kenji's durability. Excessive use of Kyōfūban leaves his body in a weak and vulnerable state, often for long periods. Even healing Kidō can only do so much to ease the pain, making natural recovery the only solution.
