This is the prologue of the book I'm currently writing (though, given my procrastinating habits, it will never see the light of day). 

 

It was a foggy night on the research center docks. A front came through during the day, dropping the temperature and raising the humidity. As a result, the ferry to the mainland was forced to delay for a night, and the ‘guests’ scheduled to leave were forced to stay for another night.

Unfortunate for the slightly overweight security guard watching the entrance to the restricted sections of the center, not so unfortunate for his assailant.

The middle-aged white man with the brown beard never saw the small clawed hand that swept across his throat, opening it in a spray of arterial blood that splattered across the bulletproof glass of his station.

Uzume, his killer, wiped her bloodied fingers off on his clothing, shoving his still warm hand down on the biometric pad in front of his corpse to give authorization for the temporary security ID she’d set the system to print. A small plastic card with a magnetic strip and another, much older, woman’s face on it slid out of the output socket and into her other hand.

With no visible emotion, her glowing golden eyes regarded the corpse for a moment before she vanished into the mists, gliding through them toward the restricted building.

Uzume’s features were elfin and delicate, showing traces of her mother’s land of origin, but what truly stood out were the two triangular furred ears sticking out of her pitch black hair, flicking back and forth as they caught faint noises in the distance. The two sinuous furred tails emerging from just above her buttocks only gave more evidence to her inhumanity, if the eyes were not a dead giveaway.

The catlike demihuman moved with a grace and speed that no human could match, killing each security guard she came across with perfect strikes of her clawed hands, leaving their corpses to cool on the concrete. The client specified havoc and slaughter, and she had every intention of giving him just that.

When she finally reached the outermost doors, she slid her new ID card through the reader, causing the thick metal door to click open and swing outward. She slid inward and rushed the guard standing just inside before he could cry an alarm, slamming her left palm into his belly to prevent him from crying out before thrusting her right index finger into his left eye, using the grip this gave her on his head to draw the head back to bear the throat, which she bit into without a second’s hesitation, ripping his throat out with her razor sharp canines.

The taste of salty, warm human blood upon her tongue threatened to send her in to a state of excitement, but she forced it downward with the same iron will that allowed her to survive her life so far. She dropped the human to the ground at her feet, pocketing his sidearm for later use, along with his two spare magazines of 9mm ammunition.

In the next room, she found another guard sleeping, and, using the claw at the end of her right index finger, precisely pierced his voice box without harming the nearby arteries, ensuring he wouldn’t be able to cry out an alarm. Two slashes of her claws separated the tendons at the elbow, and she jammed the edge of her hand into the wound before using a spell to force-heal it, sealing the skin, flesh, and bone around the damage without undoing it. She couldn’t afford for him to die just yet, but she didn’t want him able to struggle effectively.

With impossible strength, she dragged him to the nearby biometric scanner , forcing him to activate the combination palm print and retinal scan, opening the doorway into the center’s inner sanctum.

With the same carelessness a child gives to a discarded toy, she snapped his neck and dropped him to the floor, flowing through the open doorway before it could shut.

There was no guard at the station inside. Unsurprising, as by all accounts the facility’s security budget was cut by the current project manager only weeks before. The assault rifle armed guards on the grounds and the two layers of biometric scanners probably seemed more than enough to prevent intrusion in the eyes of a scientist.

A young woman, most likely in her mid-twenties, stepped out of a nearby room, rubbing bleary eyes, her labcoat stained with chemicals that smelled sour to Uzume’s oversensitive nose. Without hesitation, Uzume slammed her right palm into the woman’s nose, forcing her back into the room she left, even as she drove stiffened clawed fingers deep into her belly, tearing through her innards viciously, shredding her stomach and ripping deeply into her left lung.

Seeing two other scientists behind the woman, looking stupefied, she leapt over the woman with a display of inhuman agility and tore the face off one, twisting in midair to hit the metal wall feet first before launching herself to tear the throat out of the other. The gurgling noises of the dying were all that signified the three terrible blows dealt, and Uzume noted that she had cut half of face-torn one’s tongue out, causing him to choke on his own blood.

With a sigh, she slammed the heel of her booted foot into his throat, crushing his trachea. His eyes were gone, but a witness was a witness.

Uzume’s form-concealing black clothing was already soaked with blood, and her face was splattered with it, especially around her mouth. She took a moment to use the dying woman’s labcoat to wipe the worst of it off of her face before moving on in perfect silence.

She also wiped the caked blood off of her claws with a white cloth as she continued making her way through the facility, stopping at each room to kill those within in perfect silence. Most didn’t even have time to react before their corpses hit the floor, and that was no surprise. The speed with which she moved was beyond the human ability to react, to the point where two or three were usually dead before any remaining individuals within realized something had happened. Uzume’s kind lay outside the realm of human common sense, which was why they were so effective at work like this.

It took her almost an hour to clean out the accessible areas of the facility, literally painting the walls red in places. Going back through the facility, she used the drying blood of her victims to write a series of symbols on the wall of each room before heading for the way out.

As she reached the door she came in through, she activated the spells with a thought, and flames burst into being throughout the facility, erupting from the blood within, burning everything, starting a conflagration that would gain the attention of the rest of the facility as a whole within moments. Unfortunately for anyone investigating the incident, there wouldn’t be enough material evidence remaining to get even the vaguest idea of what had happened.

Uzume stripped naked, tossing her clothing and boots into the flames inside without a second thought, gliding back into the mists with the same grace and silence she’d displayed upon arrival.

As she left the grounds, her body shifted, the ears and tail melting away, her metallic golden eyes becoming a mundane brown, the blood in her hair and on her skin vanishing as it was consumed as an afterthought to power the shift.

So it was that a young human woman named Uzume, an unremarkable half-Japanese woman knelt down in a group of bushes and dressed in the plain school uniform she’d used to gain access to the island. There was no sign of the terrible grace and horrifying brutality she’d shown only minutes before in the slow, shuffling gait of the woman that remained behind, though their elfin features were the same.

She made her way back to the employee dorms ‘her class’ was staying in without the least sign of guilt or concern, for all the world as if she really were the young student she appeared to be…
