Aura Shell

Aura Shell (霊気貝, Reikikai) is a technique developed by Kazuhide during his youth after witnessing the  utilized by. In lieu of bolstering his offensive capabilities Kazuhide formulated a method of increasing the durability of items by channeling chakra into them. The technique operates by flowing chakra within and around the item in question, effectively strengthening the material beyond its natural capabilities. It should be noted that the chakra used in this technique is invisible to the unaided eye, disguising the performance of this skill to most onlookers.

With this skill Kazuhide was able to intercept the blows of several swords of pristine quality, with a rusted and discarded armament. Furthermore, by using this technique with a blade of average quality he was able to inhibit the cutting potential of chakra flow enhanced weapons, without his blade receive so much as a scratch. While this technique is mostly employed to increase the durability of bladed weapons, Kazuhide has also employed the skill upon other items as well. When used in concert with a bow, the elastic limbs become noticeably more rigid. Thus, if this technique is applied to a bow at the moment the arrow is released the energy transferred to the projectile is greatly magnified, allowing the arrow to be fired at much greater distances and speeds than would be possible from the weapons natural design. In addition to weaponry, Kazuhide has also applied this technique to his clothing at times, giving him a makeshift armor. More specifically, his use of the technique on his jacket made it possible for him to survive several arrows from piercing his back. It should be noted that despite his efforts he was left with bruises from the projectiles, demonstrating that the force of the assault was not completely obstructed.
