Kirigakure no Sakuretsu
And the utter desolation of all material things.
The Sakuretsu clan was a peaceful entity on the cusp of scientific breakthrough, working in their compound located within the gates of the mysterious and widely tumultuous Kirigakure no Sato. Despite its ties to criminals and other characters of ill repute, it was the perfect stowaway spot for their crowning achievement—a construct most heinous by human standards—the birth of a living radioactive bomb.
It was their home and they appreciated it for what it was, finding it pertinent to maintain the seclusion that Kirigakure offered them. They were no strangers to bizarre experimentation in the physics field. Their bloodline extends to antiquity and can be traced back to a couple named Aiko and Rihatsu. Brilliant nuclear physicists, even for the low standards of what constituted the scientific community in the earliest days of the unified shinobi continents. These two lovebirds tirelessly experimented on the human body, extracting and implementing energies from any sources they could find and creating an anomaly of the natural. Adaptation took its course in their bodies from the constant barrage of substances harmful and helpful alike, laying dormant in their bloodline the potential for a chain reaction that festered like a cancer.
War engulfed the lands, smothering it in strife and drowning it in blood. All of their energy became focused into the construct of this weapon they had in mind, which not only crossed the line of science fiction so much as it threw up on it. In their effort to achieve something over enemy nations and secure almost certain victory, caution was thrown to the wind and more aggressive field testing was achieved. Several months passed from this point and the clan had managed to create a ticking time bomb from within their compound set to detonate at the first instability. In their haste, they thought nothing of it, but the curtain was being yanked back for a terrible event to take center stage.
Kirigakure experienced the worst negative cosmological surge anyone could have committed to imagination, opening the path to what is now referred to as The Great Mist Explosion. It was a potent blow to many of the people who inhabited the village, and most of them succumbed to swift death. After the Sakuretsu had been exposed to the barrage of cosmic energy, their chakra pathway system became destroyed and rebuilt through a foreign subtype of γ radiation inherited through years of unnatural selection. This reaction was carried into their bodies on a molecular and subatomic level, triggering a process that orchestrated changes in the fabric of their deoxyribonucleic acid.
They had achieved their goal. The Sakuretsu had became their own perfected endgame.
The Sakuretsu are imbued with chakra that reacts to certain things that come into contact with it, instantaneously becoming unstable and bursting apart, moving outward with blunt force trauma that primarily serves to inflict damage to a target on the surface level. These are not explosions in the traditional combustion sense, but involve the transference of force through energy. For their chakra to reach a state of instability, it must be coerced with an adequate opposing force. It doesn't take much, but it allows for just enough margin so that the members aren't perpetually unstable. While something like molding their chakra in their hand and allowing it to embrace natural wind or water wouldn't do it, use of the kinetic energy produced by the body during physical combat would. The resultant explosions become reabsorbed back into their own bodies and nullified on their end, and thus they do not inflict harm to themselves in this manner.
This is another method for the members of the clan to use their ability. In essence, by storing up some reserve of their chakra into Fuuinjutsu seals, it can be made unstable and thus detonate when triggered to release from that which the seal is implemented. The scale and destructive potential of these seals depend on the chakra output involved in each, which correlates to the skill level of their creators, with the smallest application spanning your average shinobi tool like a shuriken or a kunai and acting similarly to a basic explosive note. While the raw manifestation of chakra acts as a more immediate assault, these allow for timed detonations, and can be crafted with strategy in mind. Furthermore, the Sakuretsu can even implant the seals on human bodies, or anything really, creating a kamikaze out of themselves or directly blasting a person into sanguine pulp (with OOC permission of course, as with anything lethal or potentially so.)
This mostly applies to the modulation of general ninjutsu molding, but nevertheless, the explosive properties of their chakra can be altered from their natural state of basic destruction and create a morphology that suits different needs. This is known as the Release Hierarchy.
Area of Effect: Designed to cover the widest span and completely envelop a target.
Shockwave: Radiates shockwaves upon detonation, affecting the ground the most.
Vibrational: Converts active force into disorienting and possibly crippling vibrations.
Percussive: Creates booming and deafening sounds to the sense of hearing.
Rebounding: Not centered on damage so much as forcing the target away.
Condensed: The most damaging type, since it compacts to a specific point.
All members are instructed on the basis for how their chakra is and all of the history that went into the creation of it. As such, the most important lesson a Sakuretsu child can learn is that he can't simply go out molding his chakra around other people without the possibility that the person can get seriously injured or killed. Furthermore, it is a lot more difficult for a Sakuretsu clansman to use their chakra for even simple tasks like standing on top of water or clinging to a wall. While it is possible to do all of the normal applications chakra can do, the user has to take meticulous steps and show caution not to apply enough force to his footfalls to make the energy unstable. Walking or running probably wouldn't do it, but using it to land after a significant fall blows a hunk out of the ground and catches nearby people in it.
Their appearances are indiscernible to most people. Many of them have opted to dress as civilians in order to exonerate the public display of having ties to any particular shinobi village or organization. In the same vein, there are some Sakuretsu clansmen who are no longer classified as shinobi, but as civilians, obviously holding the same level of skill as they can acquire from the principles they learned as
shinobi. The oldest members of the clan adorn monocles in order to supplement their failing eyesight. Largely scientists and researchers, their studies and findings have to be kept to a consistent degree. This lends a deeply analytic predisposition to members who hail from this clan, as nearly all of them are born from a stock of ancestors who showed remarkable development and intelligence for their respective time periods.
This clan can best be described as having a lawful-neutral disposition. If there is ensuing chaos that has the potential to spread, according to their doctrine, bringing balance is something that a Sakuretsu should always strive for. As such, it is usually in their nature to try and settle serious confrontations before they escalate. Entropy is perhaps their biggest rival over all other aspects, with the inevitability of disarray working against even the smallest measure of control that a clansman wishes to achieve in his environment. That said, should the need arise to fight for their own sake, they will wreck your f.
ucking face in accordance to the divine law of self-preservation.
