MechaGirl Storia: Miko's Origin

For a long while, the small city of Amber Hills has been protected from all threats by its heroine, a sentient mecha superheroine known only as "MechaGirl M". Nobody knows who she is, never mind how she came to be, yet for young 10-year-old Mikoto "Miko" Shirogane, how she came to be the city's greatest defender is still fresh on her mind.

----

To be really fair, she wasn't supposed to be here. She shouldn't supposed to be in this bunker, and definitely shouldn't be opening some random containers holding something... peculiar.

All alone in the empty hangar with the underground research bunker, Mikoto "Miko" Shirogane was wearing a strange bodysuit that she found in a broken container, somewhat completely intact, only for said bodysuit to tighten around her body as it was readjusting to accommodate her physique.

She felt a bit of discomfort as the Suit tightened around her, though it soon faded away, now replaced with a strange sense of familiarity.

Before she could figure out what was going on, she soon heard a loud sound, like a door being opened. She walks through to see what looks like a empty hangar, something similar to that of most airplane/mecha hangars seen in most animes.

She could have sworn the hangar was empty, and yet, a voice in the back of her head whispering to her about something...

Subconsciously, she whispers, "MechaSuit, Initialize!", and just like that, she was enveloped in a bright flash of light. Everything felt so fast, yet everything looks so slow to her.

"Huh, what is going on?", Miko asked to herself as she suddenly felt a breeze wheezing in the scalp of her head. She then touches her head, only to felt something soft... and hard? Miko then look at her hand and was shocked to see what's on her hand.

A handful of brown hair. Her hair.

She gasped in horror, just as the rest of her hair falling off her head to reveal a smooth, shiny metallic scalp that spreads out to the rest of her body, soon covering it in a sheen metal finish. Somewhat horrified, Miko tries to take off the bodysuit, yet she cannot find it, apparently realized that it literally fused with her body, making her part-metallic human or more accurately, a half-robot.

Before she has enough time to comprehend all of it, she could suddenly feel her whole body remolding from the inside-out. Her hands and feet grew smoother and more mechanize, while her elbows and knees took the shape of a robot's joint structure. After the transformation to her arms and legs was completed, she stood up, already feeling wobbly on her new and seemingly heavy legs as she nearly trips over her own foot.

"W-whoa! Wh-wha, what's going on? What is happening to me?!" Miko bellows in horror, but she receives no answers in return. Soon, she gasps in pain as her insides reforming themselves into machine-like components as her torso was reshaping itself into a more android-like appearance. The pain, for some strange reason, was both soothing and agonizing at the same time, with Miko wanting to cry out of unbearable pain... except she can't. No tears coming out of it, other than the silver-like substance that was slowly covering her eyeballs from within her skull. Worse still, she was unable to blink as the metallic skin in her entire face starts to harden, leaving her staring out in the open with her vision diluted with shades of silver before it became transparent and crystal-clear. Miko could only wonder how she can still see, despite being unable to blink, before getting her answer a few seconds later. Apparently, the bodysuit's properties somehow changed her organic eyes, allowing her to keep her sight even without her eyelids.

Looking at the mirror placed in front of her, her eyes (which now sporting sapphire-like scleras) widened in shock and disbelief at the very clear reflection of her de-fleshed, fully-metallic head. She yelps as the rest of her body underwent the same process of becoming mechanize: the flesh being eaten away and replaced by a metal finishing, the nerves and internal organs reconstructed to machinery, her skeleton disassembling itself and rebuilding back inside her machine-like shell, and her bodily proportions shortening little by little, though keeping a relatively young-looking youth as the bodysuit's nanomachines "worked their magic" on her.

The moment the transformation was complete, Miko's body was already completely enveloped by her mechanized suit, the grayish-chrome exoskeleton shone brightly with a metallic gleam under the bunker's lighting. Taking a closer look at her new metallic frame, the mechanize girl finds her nails elongated and solidified, turning into sharp claw-like digits, her fingers becoming skinnier and her hands smaller, with her forearms shortening ever slightly, while her upper limbs remain plump and effeminate in shape, complementing her smooth and shiny new shins and ankles, as well as her slender legs. Looking at her transformed lower-half, her privates were completely non-existent as being a robot means she is entirely genderless.

Despite being entirely made of metal, Miko felt surprisingly light, still able to function like a normal human being... albeit her current state was far from it. She was a robot now, an autonomous thinking machine, or a "gynoid", if one was to be exact.

"W-wait! If I'm a gynoid now, does that mean... that I am an android, now?! I don't know how to feel about this! What happened to my humanity?! I still feel human, but not quite. It's all so confusing!" the mechanize girl wonders to herself, before her attention is diverted elsewhere, her gaze locked upon the metallic reflection of her newly mechanized face. Her skin was replaced by a cold metallic finish, her eyes are no longer organic, and her mouth now has metallic teeth inside. Her nose was also gone, and her hair was no longer there.

As Miko looks over her mechanize body, she finds her torso had also undergone a drastic change. Much of her body shape and size remained unchanged, being a young prepubescent girl at that, yet the Suit's microscopic nano-machines had somehow made her look "cuter" in her new mechanize state. Her bust has increased significantly, now being a slight A-cup, and her hips and thighs became a bit thicker and fuller, making her look more appealing in appearance.

"What the?! What is happening to my body?!" she wondered, her mechanize body shuddering a bit. The sensation of feeling her new form was something she never expected, being a mechanized gynoid.

"Well, I suppose the only way to test my new form out is to put it to the test!" Miko said to herself as she walked around a bit, getting used to her new robotic body. As the mechanize girl got up, she began walking around the room, moving her limbs around as she was trying to get used to her newfound agility. Eventually, she was able to move about freely, no longer having trouble moving about, until she accidentally bumped into a wall, leaving behind a sizable crack of the wall and knocking her back a little.

"Ow! Geez, guess I need to be careful from now on. This body is so much more fragile than my human one, yet I can still function normally, despite everything."

She continues moving about the room, before she stops at the middle. "Alright, let's see how far I can go with this. I'm going to try to make a leap! Here goes nothing!"

With a mighty leap, Miko jumped up, reaching the ceiling, and then falling back down. When she landed, however, her impact caused the floor to shatter underneath her feet, leaving a small crater in its wake as the mechanized girl reorients herself back up. "Whoa! Talk about an incredible amount of strength! I guess these mechanize arms and legs really pack a punch."

She turns around, looking over her surroundings. "Now, what should I do next? I'm not sure what else I can do besides this. Maybe I should just stay here for a while, or maybe leave and go exploring."

The mechanized girl decides to do some more tinkering with her new body, concluding that she can change her mechanical body however she wishes thank to the fact that she has access to an internal database inside of her head. Not sure how she would react to this fact, but at least she learned something new.

"Blank Mode to Valkyrie Mode, Initialize!"

A bright flash of light engulfs her body as Miko's mechanical body undergoes a metalizing metamorphosis. Her body suddenly elongating as it was reconfiguring itself in preparation for her new body, starting with her arms and legs.

Her arms reconfigures itself into a more shapely pair of long and slender arms with a pair of delicate hands and slender fingers, while her legs also undergo a similar transformation, her hips now noticeably wider and curvier. Her torso, meanwhile, also expands a bit as metallic breasts mold from them into a nicely shaped C-Cup chest. Her robotic face then underwent its next transformation as her cheeks hollows out, becoming slightly rounder and plumper, her lips puffs to a more fuller and more kissable shape, her overall facial shape also becomes slightly angular and oval-shaped, and her eyes changes shape from its circular oval shape to a more diamond oval look.

As she winces in shock with each changes to her mechanized body, something else was changing in Miko, who quickly notice of it. Normally, her transformation was initially a horrifying experience, being a young girl after all, but this time, she doesn't feel anything wrong at all, no pain or discomfort whatsoever, just pure pleasure and excitement. The sensations coursing through her body feels strange, yet strangely good.

As if she matured rapidly and became an adult woman in the blink of an eye.

"So this is what it feels like to become an adult," the mechanize girl muses, then immediately noticed that her voice was... different. It was no longer high-pitched and squeaky, but more mature and sultry-sounding, slight sensual and seductive in tone. She also noted herself of how different her body acts, as earlier, her body language was more that of a child's, immature and clumsy, and lacking in confidence, but now, it feels calm and poised, comfortable in her skin.

"Aww, check me out~" She happily cooed. "I'm growing up quickly~", she then shifted to a more teenage-like tone, "Like, this is so freaking awesome~! I'm so fucking hot!~"

The mechanize girl looks over at her own reflection on the mirror, now noticing that her body was now sporting a more curvaceous and slender appearance.

"Hmmm~, my boobs are getting bigger~!" Miko commented, groping her hard metallic chest. "A lot bigger, too~. It feels nice and heavy~"

She then lifts her new mechanized body, taking a good look at her new form. "Wow~! My body is so slender and sexy~!" she exclaimed. "My tits are so big and firm~! I wish I could go out and show them off to everyone~! I bet they would love it~!"

The mechanized teenager, with a sly grin on her face, then added, "But not without one more upgrade..."

"Valkyrie Mode to Goddess Mode, Initialize!"

Another flash of light once again engulfed her entire body as Miko underwent a new transformation, starting from her torso. Her bust size grows larger by about a cup size, making her bosom a large D-cup. She then felt her legs elongating to match her body frame, which makes her taller as well, her already firm and supple ass also grew in size, becoming even more curvaceous and luscious. Her arms became more toned and slightly muscular, while her hands became dainty and slender, with her fingers being longer and more graceful. Lastly, she felt her face grow more feminine and delicate, with her cheekbones becoming more defined, and her lips becoming fuller and plumper. Her eyes took on a more mature look with a pair of eyeliner accenting them.

As she finished her transformation, Miko couldn't help but giggle and sigh with satisfaction as her new form took its shape, with her mechanical body having the same proportions and measurements as a grown-up woman in her twenties. "Now this is a transformation worth taking~" she said seductively.

"Oooo~, I like how I feel like an adult woman, and look like an adult woman now~." The mechanized woman continued, as she started posing in front of the mirror, admiring her new body.

She then giggles again, this time sounding much more adult and alluring, with her voice becoming more mature and sultry. "Hehehe~, my body feels so hot and really good~," she said, slowly letting out a deep sigh of satisfaction, her voice still sounding sultry and mature.

"Wow~! I look hot and sexy!~" Miko exclaimed in a very seductive tone, "Hehehe~, I feel so hot and excited~! I love this~!" She continued as she posed seductively with a confident and seductive expression on her face.

"I want to do something with my body~!", Miko ponders to herself, "I mean, I'm a sexy and curvy robot woman after all!" At this point, she was already getting used to her mechanized body, no longer finding it to be too foreign and alien.

She then turned to look at her reflection in the mirror once again, posing seductively as she said, "Alright! Let's see how far I can go with this~!"

As far as she know, the Goddess Mode was the last of the four modes she can normally access, but the database was vast, meaning that she can go even further than her current form. For one, perhaps she could try to turn into the AileStrike, a pink and red Valkyrie-type mecha designed for aerial combat.

Being turned into a gynoid is one thing, but turning into a giant mecha, now that's another story! She was already initially terrified of her first transformation into a gynoid, so who knows how it feels like an actual giant robot?

However, she was more excited and eager to try this out than she ever imagined, and she wasn't afraid of what might happen if she tried it.

She then said to herself, "I wonder...can I transform into a Valkyrie-type mecha?"

As she closed her eyes, Miko began concentrating her mind and will, her mechanical body started to glow brightly in a soft blue light.

With a deep breath, she shouts, "Goddess Mode to AileStrike, Initialize!"

A sharp flash of blue light enveloped her body as she felt like she was getting taller... maybe a bit too much.

"Okay, okay! Too much!" She quickly says as she feels like she is getting tall. While all of this is going on, her ample chest shrinks to a sizable C-cup and her hips slightly deflate, prompting a response from Miko, "Aww, my boobs got smaller...! Well, at least they didn't fall off. That would be weird..."

Her height was now at least the size of a small building, with her being a good 8 meters tall (or 26 ft).

Looking around her, Miko was now looking at her surroundings from a different angle, a very new experience for her, she felt rather powerful and imposing as she is now, though the sensation was somewhat familiar to her, as if she had been in this situation before.

"Huh, that's strange," Miko says to herself, "Why does it feel like I'm not new to this? It feels so...familiar..."

She then shook her head and said, "No time to ponder about that now!" As if on cue, her body slightly winces as lumps of metallic silver "flesh" sprouts throughout her all-metallic body, mainly her arms, legs, torso, and head. These lumps then started to shift, spread, and reshape into pieces of armor, all of which looked rather feminine and elegant, though with a few futuristic design elements that gave her a unique look, before they quickly solidified and melded together into her body, with the only parts remaining exposed being her face and abdomen.

Her legs in particular have many jet thrusters forming into them, with a pair of boosters on the heels of her feet, while each of her shoulders are equipped with smaller thrusters on both sides, allowing her to fly through the air. Her helmet forms as a sleek helmet with a retractable mouth piece. Her breasts slowly reforms into what looks like a jet fighter's nose, surprising Miko even as she struggling to remain calm throughout all of this. As her chest was done reforming, something else was forming inside her chest, a large crystalline chamber right in her cleavage.

"Whoa~?! What just happened to my boobs? D-did it just turned into a jet's nose?", Miko freaks out, "Also, what's that thing in my chest?"

Suddenly, she winces as something is beginning to form inside the crystalline chamber. Inside it, metallic "flesh" deforming around as it reforms itself into a variety of switches and a couple of handlebar on both sides, with three monitors surrounding a single chair.

In other words, a mecha cockpit was formed. Her cockpit.

Of course, she doesn't know about this as the slight pain in her chest faded, leaving her to wondering what was that all of a sudden. "Hmm, weird," Miko wonders. She then taps her mechanized finger at the chamber, opening it up and was surprised to find a comfortable pilot seat with a myriad of controls, all of which were foreign to her. "Woah, is this a cockpit?", Miko asks herself, "Why's this here? Hmm, it looks so comfy."

Then, she notices three screens on the front and sides of the seat, all of them showing off live footage of her surroundings, with the central screen shows her current point-of-view and the side screens showing everything on both sides. She felt big and powerful in scale like in those mecha anime she's watching often, she suddenly felt... complete, like she was not born a human, but rather made in a factory as a gigantic robot.

She then touches one of the handles with one of her giant fingers on her left arm, suddenly feeling her right arm lifting itself up on its own, as if being controlled by someone in the pilot seat. Miko was freaked out a bit, but then relaxes as the sensation felt really good and familiar for some reason.

"Okay, okay, calm down, Miko!", she tells herself, "It's just a suit, a really advanced suit. Just think about it this way: you are just a suit and you can control it from the inside! Just like in those anime!"

Then, it hits her. The body, the feel, the cockpit, all of it tells her of one thing: she has became the AileStrike, the mecha that was now her current body, both inside and out, and yet...

She was able to move this big body likewise with her human body, not to mention retaining her sense of self. It was as if she was a human soul in a robot body, which is true in a sense, except she has no human body to return to anymore.

"Well, I guess there's no point in freaking out anymore...", Miko realizes, "Besides, I have to admit it's pretty awesome being a huge robot like this! Hehe~!"

Miko also noticed her own body language was visibly different from how she acted as a human, and so does her voice. It felt, moves and sounds... womanly, confident and sexy even. The beautiful face, wide hips, curvy figure and large breasts (if she can even call it one), all of it she has possessed now, as if she was an adult woman who was born a giant robot.

"This is going to take some time getting used to...", Miko said to herself, "I mean, it feels so awesome! I have the body of a 20-year old woman for god's sake!"

It then takes her a few minutes to get accustomed to her newfound form as she begins moving her arms and legs around, and then doing some stretches to get used to them, she even tries walking a bit. At first, it felt awkward for a young girl in the body of a mecha woman to walk with such gigantic, curvy legs, but eventually it becomes natural for her as her walk cycle were evidently more sexual, strutting her hips sideways with each step. Similarly, her mannerism also slowly matures with her body, adopting a more feminine and slightly more alluring posture with almost zero hints of her previous childlike innocence.

After a few more minutes of her getting accustomed to her gigantic mecha body, Miko decided to try out her flight and combat capabilities elsewhere. She doesn't have a clue as to how does she known to have such capabilities, but apparently, as she is the AileStrike, the mecha's robust amount of software data has been installed into her as she was changing, granting her vast knowledge of her mecha body, in addition to all the combat data she needs. On the bright side, at least her new advanced memory core allowed to became adaptable to combat.

Now standing at the launch catapult, bracing herself for flight as the boosters on her legs and shoulders flaring out at full power, ready to take off.

"AS-0814 AileStrike... LAUNCHING NOW!"

And with a loud boom, Miko takes flight from the hidden entrance, soaring the skies above Amber Hills, her pink and white jet-like body shimmering like a comet, feeling the wind blowing against her mecha face, her blue eyes glimmering as she enjoyed the view, which looked different from her human form, seeing the whole city with her new high-resolution optics. Even the sounds felt different to her, a lot more distinct and crisp, and the fact that she can still see clearly despite flying at Mach-2 speed shows just how advanced her optics was.

While flying around the city, Miko finds herself easily maneuvering her gigantic mechanize body through Amber Hill's skies, almost instinctively, gracefully performing acrobatics and stunts as if she has always been a sentient mecha, spiraling and twirling about with no effort. The boosters on her legs and shoulders strikes whenever gain thrust, accelerating her body through the skies, zipping past the clouds.

As she was flying around, she soon came upon a bridge collapsed due to an unfortunate incident, and several cars were stuck on top, stranded and helpless. With her enhanced audio receptors picking up cries for help, Miko deduced that there were people trapped in their cars, and without hesitation, decides to swoop in and save them.

Upon landing on the bridge, her gigantic mechanize boots hitting the ground, the abandoned cars trembling a bit from the impact. Quickly assessing the situation, Miko quickly found out that there were no casualties, but that the passengers inside the cars were badly injured. At this point, the dozen of occupants inside the stalled cars started to notice the giant mechanized woman towering over them, confused and scared, believing her to be some sort of mechanize monster.

However, Miko assures the frightened victims that everything will be alright, her mechanical vocal processors giving her a soothing, calming voice, letting them know that she was here to help. Thinking fast, she lifts two of the cars and flies off towards a nearby hospital, dropping them off gently onto the emergency bay, telling the panicking hospital staff to rescue the occupants inside. Returning to the bridge, Miko repeats the same process with the other cars, reassuring the terrified victims, lifting two cars and flying off, before returning and rescuing the rest.

With the stranded cars now properly taken care of, Miko felt great about herself, somewhat... heroic and satisfied, just like how she would help anyone in need, no matter how mundane it was. She flies off back to the bunker, just as the sun is about to set behind, where she just stands there, wondering what to do next.

"Okay, now what?", she asks herself, confused and unsure on what to do, thinking about transforming back into a normal girl again. Suddenly, an alarming message suddenly pops up in her vision:

MECHANIZED DECAY IMMINENT...

AUTOMATIC REVERSION PROTOCOL...

STATUS: DISABLED

MANUAL REVERSION PROTOCOL...

STATUS: ACTIVE!

REVERSION PASSWORD: MECHASUIT, SHUTDOWN!

"Wait... What the heck is this?", Miko wonders to herself, confused as she has never seen this pop-up before. Thinking fast, she utters those words, clearly puzzled. "MechaSuit, Shutdown!"

Just as quickly, her consciousness blacks out as her body limping lifelessly and drops to the ground, its vibrant colors faded to a dull greyish tone as it crumbles to dust. From its dusty remains lies Miko herself, back in her human form and still wearing the MechaSuit, who bolts herself awake to find herself back to her normal self, lying on the ground.

"Huh... what happened?", she thinks to herself, getting up, realizing that she was back to normal again.

"Oh... right, it was the shutdown command. That's a relief, it worked. I better get this bodysuit packed to its container, and heading back home", Miko says, getting up and grabbing the container, packing the bodysuit inside and quickly ran out of the bunker.

THE NEXT MORNING...

"You won't believe what I've done yesterday!", Miko excitedly telling her friend Rachel Asakura at the school roof about the events that transpired yesterday, only to be met with a nonchalant response from her friend.

"Let me guess, you became a giant mecha woman who can fly and saved a bunch of people from a collapsing bridge", the blond-haired girl spoke it all off, "Yep, been through that!"

"Yeah!"

There was a long pause.

A long awkward pause.

"Wait...what!?"

"Yup!"
