Mistaken Delivery

Chapter I

-----

I don't know how this all really started…

"Are you chaos?" a tall, burly man clocked in orange attire asked him. His partner, who also wore the same clothing, stood next to a rectangular brown cardboard box nearly six feet high on a dolly, both pairs of eyes obscured by maroon sunglasses.

The tanned, silver-haired boy named chaos took a moment to examine the rather imposing box standing by his apartment door. After a while, chaos's sea greenish eyes flickered to the older man before him, nodding. "Yes. Yes I am. May I help you?"

"Sign this, please," A clipboard was then proffered to him, the black pen in the other hand. A brow arched on his face until chaos took the pen and scribbled his name where his signature was needed.

I didn't expect anything like this to happen.

When that was done, with a grunt, the second man hoisted the dolly up and chaos had to step aside from the doorway to allow him and the box to enter. With the help from his partner, they carefully set the package down on chaos's neatly polished hardwood floor, in the middle of his living room, hot dog style.

Was it Fate? A mistake? Who knows…

Afterwards, the two men stood at chaos's doorstep again. "Please enjoy." They said simultaneously, and with a bow, turned on their heels and walked away.

Once they disappeared down the hall, chaos closed his door, feeling odd at the event that just happened. Scratching his head, he turned to the long brown box that lay on his floor and openly said, "I guess this is my prize…" sounding unenthusiastic about acquiring it.

His mind began to replay how this all could have happened. It began with Gaignun Kukai Jr. forcing him into entering a raffle contest that was happening down the local street. chaos, however did it, albeit reluctantly. He could just remember that day…

-----

"Oh, come on, chaos! Live a little, why don't ya? It's just for a little fun! What harm could a raffle contest do?" Jr. exclaimed, trying his best to persuade his silver-haired friend to just try the contest out. The contest comprised of just picking out colored balls and getting the prize that went with that color. The prize was a new Realian companion, and in truth, chaos didn't see what was so fun about winning a living being.

"Really, Jr.," chaos began, running a hand through his hair. "I don't like these kind of contests. Winning Realians and things like that… It's just… Well, it doesn't just sit well with me."

But the crimson-haired boy didn't falter. Planting his hands on his hips, Jr. looked square in the eye at chaos and said, "chaos, you've been living alone for how long? I've been worrying about you, man, and you haven't taken up the offer to live with me and Gaignun!"

chaos shook his head, feeling slightly embarrassed that he and Jr. were arguing in front of the lady before the contest booth and any bystander nearby. "I don't want to impose…"

Jr. looked at him strangely. "'Impose', you say? I offered you to live with me! And besides, Gaignun doesn't mind either!"

"Jr.…"

"That's it! I'm entering you in here!" Grunting, the Little Master stalked off to discuss with the lady supervising the contest.

Blinking, chaos reached a hand to restrain Jr. from even mouthing a word to her. "Wait, Jr.--!"

"Alright, chaos! It's done! Now go try your luck!" Jr. said suddenly, beaming at his companion. This caused chaos to falter in his stride to reach him. How did Jr. manage to talk his way into entering chaos so fast?

Sighing, chaos slowly approached the intricately decorated box that was as big as a basketball. Might as well get this over with, chaos thought. After all, the probability of me getting the grand prize is close to zero. I'll lose anyway.

Letting another sigh escape his lips, chaos placed his back pack on the ground and raised a gloved hand above the opening of the box and let it sink in. chaos could just feel Jr.'s excitement sky rocket in anticipation as he began his search, and also noticed the supervisor had the same look in her mocha eyes as well. The rustle of his hand moving among the balls were heard before he stopped and raised his hand to see what color ball he acquired.

"Gold…" chaos said aloud. "What does that give me…?"

Jr., chaos, and the supervisor lady looked at the flag situated in the ground next to the box's location. The lowest color was a black, followed by a blue, red, green, yellow, white, silver, and finally…

"The… grand prize…?" The trio said in unison. Huh, so the gold was the grand prize. Psh, he should've known.

Wait, what?

"Hah! The grand prize! You won the GRAND PRIZE, chaos!" Jr. exclaimed loudly, scaring several citizens passing by. He energetically slapped chaos on the back, which brought the tanned boy to snap out of his trance in staring at the ball. For a moment, chaos was given the sudden urge to chuck the golden-colored sphere at Jr. for even forcing him into this contest, but held back.

"Congratulations, sir!" The supervisor clapped at him, causing chaos to sheepishly scratch the side of his head with his free hand. "You've just won the grand prize, and only on your first try! Could you please fill this paper then?"

chaos turned to face her. "I really don't—"

"Oh, here, fine! I'll do it!" Jr. interjected, grabbing the pen from the lady's hand and scratching chaos's name and address despite chaos's protest for him to stop. Knowing that he couldn't persuade Jr. to cease, he just gave up and placed the gold ball on the table.

Once Jr. was done, he turned to chaos and said, "Aww, don't give me that look! At least you won! Believe me, you need more friends and later on, you'll thank me for this!"

-----

That was just a week ago. Jr., for that past week, kept on calling him and asking if his prize had arrived, yet was cautious since he knew his friend would be displeased at him for a while. chaos was dreading the day his prize would come. He really didn't want to command over a person's life. It just wasn't like him. Maybe he could send this Realian back or set the person off someplace better than him.

I might as well see what edition I got… he thought, adjusting his gray shirt. It was just nine in the morning when the doorbell rang and he only came out with his shirt and white shorts. Bending his knees slightly, chaos examined the box with his sea green eyes. Nodding to himself, he left towards the kitchen and came back with a simple kitchen knife. He rapped on the top of the box first before slowly pushing the tip of the knife down. Once half of the blade was in, he used both hands to draw the knife down vertically. Grunting satisfactorily, chaos placed the kitchen knife on the stand next to his couch and pulled back the side he created.

What the…?

He did not expect to come face to face with yet another box, only, this was black, had more angles, slightly red at some point, and looked more like a coffin. Vector's insignia gleamed on the surface like a stamp and chaos stared at it for a few seconds, absently noting the Styrofoam fitted comfortably around the black box.

I didn't know Vector was sending coffins with their Realians… What, do they expect their creations to die any time soon and gave away a free coffin to save the expenses in buying one? chaos thought, staring at it. He ran a hand along the smooth surface and couldn't help but admire the sleek way it felt.

Maybe the Realian's in here… But how could… His hands flit across the exterior of the second box, wondering where he could open this…

A cry ran out of his lips once he heard a hiss come from the box. Standing up and backing away, chaos witnessed the cover pushed back and quickly opened, emitting a faint, blue glow from the inside.

Letting a few seconds pass by to let his erratically beating heart calm down, chaos slowly proceeded to peer into the contents of the glowing black bed.

What he saw amazed him to no end.

Inside was a young looking woman with long, cerulean colored hair that seemed to give itself a shine of its own. Her skin was a pale, luminescent alabaster hue, but the armor plated on her body from the chest down made it obvious what she was fit for. One of her arms was covered in a black glove and a simple ebony lace strip was circling her left thigh. For a moment, chaos was enticed to touch her lips to see if they were velvet soft, but drowned that down. Instead, he chose to flicker his eyes upon the visor situated around her head and the words engraved in the gold plate.

"… KOS-MOS…?" The name rolled smoothly on his tongue, but that soon ended when he saw the body twitch. He took a step back, just as bright, ruby-colored eyes blinked open and he was entranced, yet again, at the ethereal beauty that began to sit up and step down from her bed.

A lump lodged in his throat when those cold, ruby eyes locked themselves with his. She seemed to be scanning something, he noted, and stayed absolutely frozen, cautious that if he did something, the next second would turn into a disaster. After nothing happened for a minute or so, chaos decided to take the cautious initiative,

"Umm… Hello." He placed a hand on his chest. "My name is chaos. And you?"

Her answer was quicker than he had anticipated. "I am an Anti-Gnosis Humanoid Fighting System, serial number 00-00-00-00-1. Development name KP-X. abbreviated name KOS-MOS. As I am currently—"

"Wait, wait, hold on a second there! … Please," chaos added hastily. "Sorry to interrupt you… But you said that you're an Anti-Gnosis Humanoid Fighting System…?"

"That is correct," she replied, her voice flat and monotone.

A conclusion popped into his head, and chaos didn't quite like it. "So… You're… From the looks of things, you're… not a Realian?"

"Affirmative. Your quick understanding of the situation is appreciated."

Oh brother… chaos ran a hand through his short, silvery locks. I'm not stuck with a Realian, but an android. Something must have gone wrong during the delivery…

"Is my presence disturbing toward you?" KOS-MOS asked suddenly, her words cutting his train of thought.

"Huh? Oh, no! Of course not! I was just… thinking…"

The cerulean-haired android simply nodded. Then, after another minute of silence filled the air, she spoke, "chaos,"

"Yes?" he replied, his thoughts coming to a halt again.

KOS-MOS moved towards her black bed and immediately, the cover was soon put back in place. Then she turned her gaze onto him. "I have analyzed the interior of your home and request the use of your computer room." She said.

"Use? What are you going to do…? Hey, wait!" chaos called after seeing the android hoist the black bed onto her shoulder with little effort and proceeded towards his computer room.

She stopped and turned to him. "Do you require assistance?"

I need to contact someone of Vector. She belongs to them, not me. But what can I do…? chaos flipped suggestion over suggestion again and again, trying to think of a comfortable solution to this new problem. I could contact Jr.…After all, he did force me into that contest, and maybe…

Realizing that he had taken too long to prepare his answer, he absently checked his clock, and awkwardly said, "… Good morning, KOS-MOS."

KOS-MOS nodded in response. "Good morning, chaos." With that said, she resumed towards the computer room down the hall. Sighing, chaos leaned on one leg, letting a hand rest on his hip, his eyes sweeping over the remains of the cardboard box that held KOS-MOS.

chaos couldn't possibly leave KOS-MOS alone now – she didn't seem intent to leave yet, anyway. What, with her confirming she was a battle android and all. Yet the android seemed to be of a valuable piece to Vector Industries; surely they'd come looking for her soon.

But that suggestion gave rise to another idea. Vector Industries would probably come, yet, seeing their precious equipment in the Kukai Foundation, they'd take it the wrong way, probably a plot trying to steal from them, and agreements between the Foundation and Vector would be frazzled even more. Gnosis attacks were increasing in several sectors of the universe, and that gave Vector (not to mention other political powers) lots of stress. Still…

Seeing his only option was to contact Jr. and discuss about this problem, chaos sighed. He turned to the place where KOS-MOS disappeared to and decided to just check on what she was doing later; it seemed she didn't want to be disturbed. Then again, this was all new to him, so he couldn't come up with anything else other than that. He didn't want to be rude to her.

"I guess this leaves me to properly dress for today…" chaos said aloud. Decision made, he walked into his room.

Holy… Crap…

These were the two words that echoed in Allen Ridgeley's head when he found not an android, but a Realian in their shipment. A Realian!

Where was KOS-MOS?

"Uhh… Well… Isn't this bad, huh?" Togashi said from behind, scratching the back of his head as all members of the First Division R&D Division stared at the sleeping Realian in the box.

Bad? Not finding KOS-MOS today, bad? This was…

"So, Allen… Heh, heh," Togashi continued, straightening his collar as sweat rolled down his cheeks. "I… guess we're in trouble?"

At this, Allen exploded.

"TROUBLE? Of course we are! Chief expects daily – and when I mean daily – I mean periodic, every day progress reports of KOS-MOS's activities! OF COURSE WE'RE IN TROUBLE!"

Yup, they were all screwed.

And if Shion Uzuki ever found out about this mistake…

Well, let's just say that she'd raise hell.

And where is Shion Uzuki, you ask?

Of course.

She's on a forced vacation.

That's the first chapter. If you're interested, please review. I only ask for that much. See you all if I'm lucky enough to put in a second one.
