Adamantine Body

Adamantine Body (金剛体, Kongōtai) is a technique learned by those that train under Seireitou Kawahiru.

Description
One of the first skills acquired by those that study under Seireitou is the act of manipulating the degree to which reiatsu is released by the body. Spiritual pressure is always released by an individual's body depending upon the concentration of reiryoku; its intensity, potency, reach, and overall strength proportional to an individual's spiritual power. Mastering one's power is key to being able to control the output of spiritual pressure, this is a basic skill taught to all and has been mastered by the Captains of the, which is the reason why their massive reserves of reiatsu isn't being exerted at all times, which could lead to various consequences, while also allowing high-level warriors to conceal their presence from spiritually aware beings.

After mastering the Adamantine Fist, which is the method of drawing in one's spiritual pressure and focuses it onto a single point, the user further perfects this skill and manages to compact the entirety of their active spiritual pressure onto their body; literally turning the body into a clenched fist. In doing so, not only does it allow a user to erase their presence from those that lack great skill with spiritual awareness but causes their body's defensive capabilities to become vastly enhanced. The user's body, in terms of both durability and overall strength, is increased by a factor of nearly three to five in the most common cases. It has been likened to the effectiveness of a  or an. And similar to that of the Adamantine Fist, usage of this technique often results in a distortion of the air surrounding the user's body, due to the immense degree of compressed pressure.
