[Black World Arc]: The Madness, Reversed.

Crack and spit. How disgusting this world is, yes, 'this world', the other side of the mirror which created the Black World. Unlike the real world, this realm consists as the polar opposites of the real, the 'truth' that lies deep beneath the mirror itself, reality that brings together the entire world. Why did they invade? Well, no one is sure of such reasons of how such full-scale attack even came from the first place, whether it is to replace the real world or to obliterate those who polluted it with corruption by the technology and power that they hold dear so much. What a sin, what stupidity, that they should've willingly be taken over by their counterpart because they tried too hard to avoid reality, the part where they have been avoiding, the side of their personality that makes them 'dark' in the first place. Even the nicest person in the world would have the darkest personality regardless of who or what they are, and the cruelest person would have the brightest personality, and this exploits the true nature of humanity, to show that such trashes have no such rights to exist without understanding the true nature of their life and persona. This is what makes the Black World special, because it exploits the opposite side of who they are, to make note who they 'truly' are. The manifestations of goals, emotions and thoughts, and the mirror of those thoughts would be created in this world.

True fear would be struck into even the bravest ones when a certain being took its arrival to this bloody battlefield when a sudden explosive power began to crash like a meteor into the entire area, several miles wide that even when they are far away from the core, those who are within the radius would feel pressured, even fear against the mightiest of warriors. Insanity was leaking together with these almost ominous pressure, and for the fact to know, this overwhelming pressure isn't anything that even the beings who excel in the area of detecting spiritual energy would understand. Its not reiatsu, Za Koa, chaos energy or anything that can be categorized as an 'energy', because if it is, even energies that is classified as 'unknown' can be easily recognized to be a part of reiatsu-like pressure booming across the area, however, what is this insanely-filled pressure that even has enough power to make those are of 0 tier to know that this presence means business, and 1 tier to kneel down if their willpower isn't enough to fight against the overwhelming insanity and chaotic pressure that simply crushes down as if they were standing directly above a black hole. If they would've guessed it, yes, it is nothing more than natural pressure itself, no trickery nor was there any necessary means to induce such effects or exert such power, because the pressure itself is naturally produced and unleashed by a specific individual. It would be sound impossible to one's mind for anyone to achieve such level without any supernatural energy, but it is, because there is one human who can achieve superhuman levels without the need of any.. spiritual energy or outside help, because he was already born with such power. Natural pressure bearing down into the area like mountains stacked behind them, and it was nothing like a human but truly, a fact is a fact, when 'he' appeared, because with such destructive power would only point at a single person, the Nightmare himself.

Insanity driving the area heavily like a nuclear warhead, those who had fought the Nightmare before would easily feel the difference between the original and the Inverse, and that the entire area was creeped with so much insanity from the source itself that it is just beyond comprehension with how can it be affiliated with the normal 'madness' that the Black World has to offer. It makes this Inverse a special case at some point amongst all other Inverse beings here, because this Inverse Nightmare? The 'Originator', the Nightmare, is dead in the real world, and this young man spawned in this Inverse World just because of his 'essence', making the 'real one' theoretically alive if he were to be able to exist in this world, but in this alternate realm, the dead has revived to bring back the title of Nightmare. It would be hard to believe that the dead has returned, because this was what 'he' wanted, right? For a villain to died by the hero's hands, Shadin Yuudeshi, and stop causing chaos to humanity by his reckless actions, even after he has went through the horrendous fight against the Demon Queen, yet he insist to comply, hence his life was ended in a blink of an eye while he was still under heavy damage from the fight. However, without Shadin to notice such little details, thanks to a certain person, during the Australia War, the Nightmare himself had injected very little of his essence into her, and that very essence is what allowed his existence to continue without the knowledge of the Beast of Karakura himself, and because of that, the Inverse Nightmare was given life to this Black World, a realm where 'he' did not die, and of course, this world would thus born the darkest side of the Nightmare's persona, the 'hidden' mask.

He, who, had been reborn in the Inverse World, with insanity and earth-shattering pressure that crushes the land across the lands of earth. Yes, to your information, this one is completely different than the original, to those who once fought him. What makes Inverse a 'him' is the crimson red hair that smoothly flows down to the back of his neck, and almost covering his eyes, to represent the aggressive nature of the Nightmare, and as his Inverse, unlike the original, his hair is slightly dark crimson red than bright crimson red, its almost like 'darkness' has formed over his hair to acknowledge his aggressive personality. A pair of crimson red eyes, that a sharp stare to the eye with a direct eye-to-eye contact would strike the weak-willed into a short mental breakdown, forcing their muscles to become numb and fear would overrun their mind temporarily due to the influence of the Inverse's pressure unleashed by him, and a stare alone is enough to break their mind into pieces relentlessly. Standing at about 6 feet and 2 inches long, his height is not what makes him look intimidating, but the way he looks himself. Weight is basically unknown, however, his clothing seems a little off-set to his personality, which has the clothing akin to that of a bartender's clothes in a bar, except this young man doesn't serve drinks, but he serves his fists. All clothings and facial appearances aside, his equipment is what makes him 'powerful' in the first place.

Yes, equipments that should've been under the Beast of Karakura's watch in an armory of sorts and in the first place, it shouldn't be under anyone's hands as it was retrieved from the original's hands prior to his death, making it inaccessible to everyone but Shadin himself or those who wishes to get their hands on with permission to do so, since they are considered as dangerous weapons that can be abused easily if they run on a power-hungry rampage. A black-painted crutch with red stripe on the center of the crutch itself, its modernistic design is made sure that this was actually the Prototype Annihilator, the evolution from the original design, the Annihilator, but it makes many wonder of where in the world are these equipments were retrieved from Shadin's custody, but most likely, they are the 'mirror' of those equipment and belongs to this 'realm', instead of the world where the original has died. Its improvement and additional mechanics makes it deadlier than the original. Why? Simply put, instead of electromagnetic field used for defenses, now it provides a vector field around him capable to deflecting projectiles or anything that has vectors or momentum/velocity through changing its values and shooting it off to another direction without harming the user. Otherwise? Well, it grants an almost insane level of strength and durability to the weapon, without an effort for Inverse himself? That crutch alone is enough to obliterate buildings and mountains, even split paths with little-to-no effort without the need of the user's intervention to increase the output strength from his muscles.

I.E.B.N, or International Electronic Brace Network, an equipment on the young man's right wrist, a life-sustaining device for him to go through rough battles from tip to toes. Theoretically, can hold the potential to, as far as developing multi-elemental users that shinigamis can't achieve through their zanpakutos, and using the equipments he developed can forcefully create a Zanpakutō with multi-elemental use after installing it, however, it is just his speculations, as no evidence has been proven that the method may work under any means necessary. While bearing resemblance to Shadin's choker, the Accelerator, it is purely coincidental, and having an appearance of a plain, non-stylish, dark grey in color with small white stripes at its sides and with a few visible electronic parts of the device at its outer appearance, especially the battery with a wire or two extending out of each ends of the battery, strapped tightly to his wrist with a few visible wires that is implanted directly into his wrist, each wire to his muscles, nerves and veins that transmit electrical impulses directly and throughout his entire body internally, allowing even a cripple body to function as if it is a new one. And definitely, it isn't something you should play around with, because if he flicks the switch on, things get real bloody and it won't be easy to get away from it when it happens, as witnessed by many, just a flick would be enough to have even an average captain in their bankai to have trouble fighting against him, especially if they recently unlocked it, they would have proven almost like a hindrance to him, even without the need to awaken, this Inverse, unlike Sou, could handle bankai users fairly easily without a care to give, and solely fight them for amusement, to kill them when the time becomes a bore.

All of those characteristics, in and out, are definitely 'him', Sou Yuuki, they look the same, sound the same, and yet, they don't behave the same. Sure, both of them had destructive personalities and are keen to destroy others, but unlike the original, this one is truly chaotic, with no means of conscience or guilt to slaughter those in his way without hesitations, and fight others without needing some pestering 'humanity' or 'sanity' to hold him back from being evil when the Inverse himself is truly the darkest side of the original, the 'omen' that Sou, the original, has never allowed to take over. However, that would all change when the Black World took in refugee of this corrupted world, as these Inverse would take their action to replace these filthy existence that didn't deserve to exist in the first place. Appearing in the area where these Demons had gathered and the short battle took place, his mere presence would've unleashed enough pressure that exploded like a bomb, and weak energies such as low-level barriers or just energy blasts would evaporate otherwise due to the overwhelming pressure reeking across the land, a sign enough to tell that the problem is going to be a big one, and it won't be a game about it. Yes, if the battle didn't end upon his arrival, the shinigamis would kneel down, cower in fear where instead of insanity that drove them insane, fear would seem to take over their instincts, effectively forcing them to leave without the need of interference, as well as Demons who cannot handle the intensive pressure that strikes the whole battlefield like a meteor, would proceed to leave immediately without the need to understand that it leaves just the two, the MAIN invader and the MAIN party for this event.

His lips broke into a grin, sadistical and even for a human, its too sadistic to be relate to a 'human', and that grin alone is enough to classify him to be a 'demon' rather than a human, because behind that grin was an infinite twist and twirls of insanity of this young man's mind. Without restriction, the most terrifying about Inverse Sou is that he knows exactly how much and how little force he needs to break a man, preventing any exploitable weaknesses. His laughter seems to echo throughout the place, insanity driven through his words would only speak in a disrespectful manner, almost in a tone of underestimating him, but that is just the tone, because his brain is thinking different, as it twists all the calculations within a manner of seconds as well as his equipments. Not even a second is needed, to go through everything.

"WHAT IS THIS? AN ALL-WELL INTRUDER THAT SEEMS TO MAKE THIS PLACE HIS HOME, EH!? WELL, WELL, MISTER VILLAIN, ONCE YOU'VE MET THE NIGHTMARE, YOU WON'T BE GOING ANYWHERE, AS I WILL THRUST YOU BACK TO YOUR FORMER NEST, COWER IN FEAR WHERE YOU WILL NEVER RETURN AGAIN, YOU SHITHEAD!!!"

With a light swing of his crutch on his right hand, if they are in a city? Buildings would split into two under the concentrated force of wind by 'collapsing' the vibrations against the tip of the crutch, and with a swing, the unstable vibrations would exert from the crutch and flings these air particles away like a mini-shockwave that blasted them away, and using these unstable vibrations would be almost like a star that is about to explode, where it would slowly compress these air particles as it slowly becomes unstable, and when it 'explodes', it would unleash a huge blast of vibration, concentrated in a single direction as if a sword sliced through it, but with 'force', forcing the buildings to collapse and crumble into rubbles. Without the need to think the lives of others, he wouldn't have cared if their lives are taken down. If they are in a grass field, desert or a sort of flatland, earth beneath them, within the radius of 500 meters would've begin to erupt upwards, spikes blasting at all directions before creating bigger and bigger crater every 100 meters, before the entire floor collapses after it reaches a kilometers wide, making one big crater beneath them as if a meteor impacted in this area not too long ago. A little crack in the warm-up, his eyes took a sharp stare at the man, an intimidating stare and a smile, before his words would sound as if mocking him in an odd manner.

"Come on, brat! COME ON! MAKE YOUR FIRST FREE SHOT WORTHWHILE OR IT WON'T BE FUN TO BE SO ONE-SIDED, SHITHEAD!"
