Wind Release: Air Nobility is a technique that can only be used by shinobi who have an affinity to Wind Release hence the name Sky Pledge. The training required to perform the technique teaches the user's chakra and the user themselves how to use one's chakra to tap into the air flow. When a shinobi has learned the technique from then on their chakra will always tap into the air flow around them independently of their will making the Air Nobility a passive technique that is constantly active.
