Chapter 1: Prologue - Experiment

Deep underground, through tunnels of metal and pristine white labs, two men were having a conversation. One man was taller than the other, but they were fairly similar, with matching white lab coats, and well-kept brown hair.

"So, I hear they finally managed to complete the experiment on that girl." Said the taller man, as he sat back on his chair.

"Took them long enough!" Exclaimed the other man, "I told them that eventually even one of them would have to snap. How did it go?"

"It went perfectly according to plan, although she fell unconscious after the procedure. The team that are in there say she's just waking up now." He replied

"There's a camera feed, why don't we watch?" the other man said, smiling.

"Sounds good to me, let's see what 4 years of research managed to accomplish." He replied, grabbing a remote

The researcher pointed it at a nearby screen, which lit up and displayed a camera feed. The feed shown a heavily secured room, with walls of steel several inches thick. That was only the outside layer, though. Inside, there was more reinforced walling and electrical wiring. In the centre of this cell of a room was a glass tank, with wiring and machines covering its surface, except from one side, which you could see inside from. The tank was filled with a transparent liquid. It looked just like water, but the two men knew for sure it wasn't.

The men watching switched to a more close-up view of the tank, so that they could see the inside. Looking through the glass, the men could see the naked body of a girl, suspended in the liquid. She had long, light purple hair, which was faded to a point that made it almost look white in places. Her eyes were a piercing turquoise, and she had an almost blank expression. She seemed to be studying the room she was being held in, yet her expression gave barely anything away. She was pale-skinned and young-looking, yet looking at her body, she was far from normal. At her joints and other places around her body, there were metal plates with cyan-coloured lights on them, seemingly embedded into her flesh. There wasn't any visible scars, however. In fact, she looked completely unscathed.

One of the scientists in the room, holding a device of some kind, had an expression of confusion on her face. She had her device pointed at the glass chamber, known to the scientists as 'Secure Storage 001', and seemed to be measuring something. Her expression then shifted from one of confusion to one of shock and realisation, as she moved backwards and shouted something to another scientist at the scene. All the scientists moved back, as some began to quickly type into computers that were in the room.

It was at that moment that the trapped girl's expressionless face gave way to one that could only be described as furious. Although nothing could be heard, her mouth was wide open like she was screaming. Sparks flew from the surrounding machines as the lights flickered and died, leaving the room in pitch black. Then, out of the black, a couple of turquoise rings expanded around the room. The camera footage cut out, and an explosion could be heard throughout the whole facility.

"What the hell happened? That cell is supposed to make it impossible for her to escape!" One of the men watching yelled.

"We have no idea! Everything just...overloaded!" The other man shouted in disbelief.

The two men ran out of the room they were in, to the sound of crashes, gunfire and sirens wailing with the constant emergency voice reminding them, '450 has escaped. Repeat. 450 has escaped. All forces to engage at once. All other personnel are to evacuate'. The men disappeared into the rush of escaping scientists, making their way to the emergency exit that would take them to the surface.

A squad of soldiers, clad in the finest armour the military could provide, had reached the scene. The cell chamber was a mess of sparks, debris and bloody corpses. Some looked like they'd been sliced by something sharp, whilst others didn't even look human anymore, like they'd been crushed into a wall and reduced to a red mess. Advancing towards them from the centre of the the room was the previously confined girl, but she was no longer naked.

The girl wore black boots and socks, the latter of which reached up to her knees almost. Further up, she wore a red skirt with darker red crosses on it. Covering her body was a white shirt with a black, blazer-like top over that, with golden sewn lining. All of her clothes were torn in the places that had metal plates, allowing the metal to be seen whilst she was wearing clothes. In her hands were two identical swords, shaped like katanas. Along their length were glowing turquoise markings, but most of them were unable to be seen due to the fact that a layer of fresh blood coated their surface.

"12 contacts. Human. Armed. Engage." The strange girl said, in an expressionless voice.

The attacking men opened fire, and when the bullets were about to hit the girl, a shield of turquoise hexagons appeared in midair, deflecting their fire. The girl advances quickly, wasting no time as she slices into the attacking men, killing them through their armour. The remaining three ended up backed against a wall, and in response the murderous girl created another wall of hexagons. Instead of using it as a shield, she sent it flying at the men, pressing them against the wall. She then applied more pressure, shattering the mens' bodies into limp piles of flesh.

"Enemy eliminated." Said the girl, continuing into the facility.

As she progressed, she was met with both fleeing scientists and attacking men, who she both treated the same. Both scientists and military alike were spared no mercy, and slaughtered by the girl they had kept captive. Soon she reached the exit, where a crowd of people were waiting to escape. In less than a minute, there was none. She climbed the long staircase to the surface, where she was met by a squad of soldiers with RPGs. As they fired, she used the same wall as before to completely absorb the explosion, like it was nothing. Afterwards, she used the delay where the men were reloading to kill the soldiers one by one, until only a final one lay bleeding on the ground.

"Y-You're...a...monster, 450..." He said in a weak voice, staring up at her.

"My name is not 450." She replied, raising her katana.

The man yelled out in agony, before going limp from the sword that was impaled in his chest.

"My name is Yuriko."
