Cloud Shocking Step: Instant Brake

The Cloud Shocking Step: Instant Brake (歩驚雲・瞬間制动, Hokeiun: Shunkan Seidō) is the fourth technique of the Original Eight Techniques of Cloud Shocking Step. As its name suggests, the technique allows the user to brake quickly with little damage from momentum.

Usage
To brake in short amount of time, the user forms strong and rough layer on the foot before planting the foot onto the solidified air to brake. Then the user quickly turns the surrounding air into strong but bouncy air in order to absorb the follow-up Inertia.

The technique is originally created for Momono to quickly stop himself from charging into a known trap. Apart from this, the technique can also be used when the user was thrown, pushed or blasted away in the air.

Despite being named instant, it is not truly instant as the law of physics will not allow the user to brake instantly without greatly injuring the body or even kill the user.

Real Instant Brake
While not impossible, it is extremely hard to perform the True Instant Brake (真・瞬間制动, Shin Shunkan Seidō). It requires the zeroth tier mastery on braking, which is capable of defying the common law of physic. The details of the technique is not known as only few is capable of mastering space-time ninjutsu.
