Shinpū

Divine Wind techniques were created as anti-fire techniques by Kagemori Sessai. While Shinpū jutsu contain no chakra themselves, these devastating techniques generate massive destruction upon the environment, depending upon the level of chakra used to create them.

Background
Fire jutsu played a significant role in the destruction of Uzushiogakure. Though he didn't personally witness the fall of Uzu no Kuni, Sessai has harbored a desire to defend what he loves ever since learning of the fall of his forbears' native village. At some point after his promotion to jōnin, Sessai became a sage and developed the ability to manipulate pure natural energy far beyond the level of Kwazu Kumite techniques. With his Senpō: Keitai Henka abilities, Sessai developed Shinpū techniques specifically for use against fire jutsu he held responsible for the destruction of his nation.

Usage
Divine Wind techniques utilize pure natural energy to generate mobile malleable barriers that manipulate the surrounding atmosphere. Typically Sessai uses this technique to create shaped three dimensional hollow barrier projectiles. During expansion, the barrier gathers and compresses air inside gas permeable membranes of natural energy, which the projectile walls consist of. The variable edges of the barrier exhibit the capacity for slashing, cutting, piercing, or bludgeoning opponents. At the same time, the large void within the barrier of the projectile consists of pure vacuum pressure. These projectiles can occupy any volume within the limits of the user's chakra. The greater the volume the more powerful the level of jutsu. Upon contact, the barrier envelops the target as the vacuum collapses in a controlled yet extremely violent manner towards the point of impact. The inner edges of the barrier remain capable of damaging the target as it collapses with incredible force, according to the whim of the user.

A secondary effect is that, due to the lack of wind chakra, Divine Wind techniques remain immune to the effects of fire techniques on normal wind jutsu and actually act in two ways to extinguish such jutsu: complete vacuum extinguishes fire techniques, and the collapsing membrane destroys substances, objects and chakra at the point of impact. The projectile compacts into a dense ball of compressed air and natural energy around the target only to rebound as the compression reaches maximum density. The dense ball explodes vigorously, causing extensive damage to the environment and whatever's left of the target. The pure natural energy membrane remains impervious even to Blaze Release or Scorch Release techniques, protecting the compressed air inside the membrane, as well. And is therefore capable of dispersing even these types of jutsu upon rebound of the compressed ball of natural energy in a manner similar to Shinra Tensei.
