Swift Release: Nike

Swift Release: Nike (迅遁・勝利, Jinton: Shōri) is a Nintaijutsu technique invented by Uzume Arashi after inventing the Velocity Art. By applying the mentioned style to herself, she improves Swift Release: Shadowless Flight to new heights.

Overview
By adding more Yang to Swift Release, it is theorized that this effect happens. By flowing this enhanced Swift Release power throughout the body, the user reaches levels of enhanced speed beyond Swift Release: Shadowless Flight, the parent technique. Going from speeds next to impossible to trace, surpassing Body Flicker, called instantaneous, that allows for a style of invulnerability in nintaijutsu to one that gives the user varying properties by how fast they are moving. It also allows them to control their own rate of motion, with varying amounts of kinetic energy, as well as the rate of their other processes.

Usage
This speed puts the speeds of Shadowless Flight to shame and as a result, only natural Swift Release users can use them without body damage and to their full potential (being able to calculate and perform actions as fast as they move). While this can be applied to various objects, it is specifically for the body. It gives the body three properties, depending on the speed, invisibility, intangibility and combustion, the ability to set their own body ablaze and those properties to their extremes.

By moving their body pretty fast, the user can set themselves ablaze do to the friction, and with chakra control, tame the flames and prevent them from burning their body and eventually tolerate them completely. The flames heat depend on the speed moved and can allow the user to engage in very hot nintaijutsu, similar to using a Fire Release Armour, Steam Armour or Lava Release Armor style (or even a boiling water/boiling Water Release Armor style). The amount of flames is also varying on the degree of motion, along with the user's control of the flames (dependent on chakra control itself).

By moving their body so fast, the user move fast enough so they cannot be seen by the naked eye, similar to the Hiding with Camouflage Technique and Transparent Escape Technique. No matter how fast the processes of the brain are augmented, the user themselves is literally moving so fast that the eye cannot see them in visible light. This ability also extends to the user's intangibility, where moving even faster, they can phase through directly through solids, and even chakra and energy.

And of course, by moving so fast, this energy can be given to other things. Meaning through contact, or by contact with the air, the user can set their desired target ablaze or incinerate them to ashes. Or hit them with enough force their structure collapses from the intense sound waves that can be produced by this as well.

Improvement
By using this with senjutsu, one's speed would technically improve this technique further, as well as would being a Fire Release master or Sound Ninjutsu master would help as well.

Trivia

 * One does not necessarily need to be a master of Fire Release to control the flames they produce, but most likely in order to use it the best, the user should have Fire Release, fire release training, or studied some fire release users. Same goes with the intense sound waves, one should study using the sound waves to their advantage for optimal results.
 * This technique can be dangerous if not mastered.
