Oracle's Realizer Chronicles: Prologue

Futaba Sakura, the "Oracle" of the currently-disbanded Phantom Thieves of Hearts, could only stare at the medium-sized box sitting on the floor in from of her. The 15-year-old hacker felt somewhat puzzled about its existence, for she never thought such an item would be sold like this.

Granted, she explored the dark web of the Internet and brought it from a somewhat shady online shop with her own money out of sheer boredom, thinking this is just a prank waiting to happen. Yet, she did not expect much... yet it came! And even more surprising was when it arrived two weeks after she made her purchase order without anyone knowing its arrival due to an anonymous shipping service that was used for it!

She took a seat on her desk chair while still staring at this box that had somehow appeared inside her room without anyone noticing its arrival — no delivery man nor any other help whatsoever! Even if someone did notice its presence here and notified someone about it... what good does it do? Nothing! Futaba's only option was simply for herself to try using it for herself!

Fortunately, her guardian Sojiro Sakura was still busy preparing customers with his brand of latte at the "Cafe Leblanc" below. She didn't have much choice but to risk trying to use its contents alone since she didn't want to wait until next week before Sojiro finished his work and went back home. There's no telling what might happen if he happened to find out about this beforehand... so she resolved herself to whatever might come next! If there were ever going to be complications, then there will be but nothing she cannot handle herself now that she knows about its existence! After all... she couldn't possibly let something like this slip away from her because it could solve so many things for her!

Opening the box with her own two hands (and with some cutter), Futuba hesitantly removed its lid. Inside the box were two objects, neatly placed in a styrofoam tray — one was a metal case along with another smaller metal case inside it.

Taking both out of the box, she open the smaller case and found what looks like a smartphone, looks like it was a custom-made one, and out of curiosity, she turned it on.

It was nothing out of the ordinary, save for a single app that caught her attention. The first thing she saw was a cursor blinking somewhere on her screen — nowhere near where she was looking. Curious as she is (or maybe it's just plain nosiness), Futaba tapped on it but... nothing happened. Thinking she touched it wrong, she tried again... but strangely enough... nothing happened. No response from touching this cursor! What gives?! It should've responded ...right?

Maybe I'm just too impatient. Ah well... let me just try once more. But once more won't hurt... right?

She touches the app and suddenly, a small jolt ran across her fingertips when she tapped on it... but not in any kind of pleasant way. The app then opens, revealing a whole lot of options and settings, most of them seeming rather complicated and confusing, especially to someone who doesn't know what they're doing.

"...What the heck is this?"

Futaba looked around her room. She didn't see anything that resembles a smartphone, nor did she see any sign of a computer monitor. How exactly am I supposed to make this thing work?

Futuba then chooses "Custom" out of curiosity, and a new group of settings opens up. Granted, she haven't read through the manual that comes with the package, but she was just that stubborn, she wanted to figure it out on her own.

First off, there are two options that the user can access: "Body Type" and "Age". These options allow the user to change their appearance to be of different gender and age, respectively.

Next is "Hair Color", which allows the user to choose between a wide variety of hair colors ranging from blonde to black, from red to purple, from blue to green, and so on.

Then, there's "Eye Color", allowing the user to choose from a similar number of eye colors, including brown, hazel, green, gray, blue, and so on. Also, there's "Nationality", which allows the user to choose from a plethora of nationalities, including Japanese, American, French, British, German, Russian, Chinese, Korean, Thai, Indian, Australian, Italian, Spanish, Canadian, and so on. Lastly, there is "Speech Accent", which allows the user to choose from a similarly large number of accents, including English, French, German, Russian, Chinese, Japanese, Korean, and so on.

Finally, the last two advanced settings that the user can access: are "Mental Change" and "Reality Shift".

The "Mental Change" setting can alter the mental state of the user, including replacing their memories and personality with a false one based on their preference. It also has the option to retain both sets of memories as a "default".

There is also the "Reality Shift" setting that can bend and warp the very fabric of space and time to accommodate the changes. This can be used to create shortcuts or even travel through alternate dimensions, though this requires a certain level of skill to operate properly.

Those last two settings look pretty alarming, even for Futaba, so she decided, against her better judgment, to mess around with the other options, hoping that all of this was just a joke.

She takes a look at the slider option marked "Age" and moves it from 15 to 18 before pressing "Applying Change".

As immediately as the hacker pressed it, she felt like her body was starting to get hot as if she was having a fever on a bad day. Before she can process what's going on, her height slowly shoots up, and her body changes as it goes.

Her legs, normally small, grow larger and wider, becoming muscular without any visible signs of training or workout. Her chest is quickly expanding due to the rapid growth of her breasts, which suddenly become as large as they were in high school, and now seemed much bigger than they originally should've been. She has to squint her eyes in an attempt to get used to it, but nothing works — the sight just kept growing more and more disturbing the longer she stared.

Breathing heavily, she continues to stare at her rapidly changing body for a while.

With her hands trembling with fright, she reaches up and touches her breasts, and though they're not exactly the most attractive things to be staring at... they don't feel entirely wrong. Instead of her flesh, it feels more like something soft and smooth, as if her fingers were touching down a pillow. There was no doubt about it, it was her flesh, but it also felt too easy to be touched! The only thing that felt strange was how it doesn't have any feeling or sensation on its own.

Her body then stiffens once more as her changes continue, with her arms becoming longer, and her shoulders stretching out wider. Her waist grows even slimmer than before. Finally, her hips spread out wide, giving her the shape of a woman.

And so did the rest of her skin, starting from her face, moving across her jawline until her cheeks became fuller her nose widened, and her jawline extended out, forming a cleft between them. As it continues to travel down, her lips swell slightly, becoming a deep red shade with some dark spots of purple around it. The next step down is her neck, where a small number of wrinkles form on the skin. It continued further down until her shoulders became broader as well.

"Hnn... Mmmm..."

Futaba suddenly finds herself making the sounds of a female who was about to start having her monthly period. She tries to suppress the sound, but there was no stopping it from coming out. She couldn't believe what this app did to her.

She looks into her mirror and was stunned at the sight. "How... How can my... My... My... How can I look like that?!" She's never seen anything remotely close to that in real life!

Futaba tried looking away but soon found herself unable to stop staring back. "No... No way." She can't help but laugh nervously. "I can't be... I can't be looking this good... I can't be looking so damn... Oh my god... I can't take this!"

She's still in shock that her body has changed into something completely different. If only she could see it herself as everything looks pretty blurry, and now that she thought about it, the hacker took off her glasses, allowing her to fully see everything with her own two eyes, and look back to the mirror.

Futuba now looks like a young woman slowly on the verge of adulthood. Without her glasses, she could pass as a twin sister of her friend Ann Takamaki, body and all, something Futaba couldn't possibly understand.

Her hair is long and silky smooth. It covers most of her ears and hangs down past her shoulders. Her skin is a dark olive-brown tone, almost matching Ann's. Though she couldn't tell since they both had similar colorings, she looked like she might have a light tan on her arms and legs.

A few freckles formed around her cheeks and nose, giving her a cute, yet mysterious look.

The changes to her body are mostly in the form of her bust size, which grew noticeably larger, and now completely covers her bra. She also gained more curves in her hips and waist, and her slender thighs expanded slightly. The rest of her skin tone became darker as well, with the redness from her lips spreading across her face, neck, and shoulders.

Her eyes were a deep shade of brown, almost black, with a hint of purple around them. They had an intense gleam to them that was both beautiful and terrifying at the same time.

She had no idea what this app did, but she knew for sure that it wasn't some kind of joke. There was no doubt about it. This is a real thing, and it's happening to me.

"What am I gonna do? What am I gonna do?!" She suddenly screams out loud in the middle of her bedroom, looking down at her chest, and then at her hands.

She then remembers the app has a "Revert to Default" option, and immediately pressed it out of desperation.

"Oh thank god... Oh, thank god..." She sighed with relief as the changes stopped and she returned to her original appearance.

She stares into the mirror in disbelief, "I can't believe it. I'm so stupid!" She throws herself onto her bed and lies there, trying to calm her nerves.

The last thing she doesn't want is for anyone to find out about this.

"On second thought", she thinks to herself, "maybe I should try at some other time."

Putting the phone aside, Futaba continues through her day as if it was nothing, and when night came, she decided to finally mess around with that last "advanced setting" that the app has.

With the last option chosen for the night, Futaba Sakura was ready for another change. She sits on the bed and begins to think of the best place for an experiment like this.

There was only one option: the bathroom. It's a perfect environment for it: it has a mirror on one side; it's big enough for her to move freely inside; it has a door; it has water running down on it... Everything is needed for an experiment like this.

"It's too bad I don't have any clothes on," she says aloud, "but it's not like it's going to hurt anything, right?" With those thoughts in her mind, she quickly starts stripping down for an experiment of this scale.

In the end, she wore only a simple pair of underwear, which she didn't feel particularly bothered by, as it was just a part of the whole illusion, anyway. She also made sure that her bra is on display to add some extra spice to it, which she finds oddly arousing on its own.

Next is the outfit. She chose to wear something that she knows would look good on her, something that would complement her body type and make it look as attractive as possible.

She put on a white shirt with an asymmetrical collar that exposes a bit of cleavage, along with a red skirt that stops at her knee. Lastly, she tied her hair up in a ponytail behind her head, leaving the top of her neck exposed.

As she checks out herself in the mirror again, she can't help but smile in satisfaction. "Damn, this is hot." She feels like she's walking on thin ice here, though, with every step being dangerous in its way. "Just remember: you're not real... You're just an illusion."

Futaba then reaches out for her smartphone on the bedside table. "Okay, let's get started."

First, she chooses the "Custom" option and immediately makes several tweaks to its settings. She just pressed "Applying Changes" and waited for its "magic" to work.

Sure enough, her small, petite body was beginning to slowly change, starting with her height. The first thing she noticed was how tall she got until now that's over six feet tall (something that would normally be impossible). Her boobs grew bigger by several cup sizes while simultaneously raising their shape into rounder ones which were probably also due to gravity's usual effects on breasts during puberty (or so she hopes). Her hips widened at first before gaining more curvature along with toned legs that became thicker with each step she took towards that bathroom door. Her stomach grew wider as well while stretching out further than before toward her lower back where two smaller but still noticeable muscles formed from there down below to support it all together.

Finally, her skin grew much paler as well, especially on her face which had a subtle glow to it. The freckles from her cheeks spread to cover more parts of her face, including under her nose and around her eyes. Her lips were fuller as well, but not to the point of being obscenely thick.

The changes were coming faster now, and she knew for sure they would only continue getting more extreme as time goes by. Soon enough, it will become difficult to keep track of her current appearance and that's precisely why Futaba decided to start recording it all on video, even though she wasn't so much if the video was ever recorded at all due to reality shifting around without her knowing it!

The changes continues as her hair became longer, curlier, and darker in color. It covered a little more of her shoulders than before as it hung down past her upper back now, with many strands hanging freely down from the front that was held in place by a single braid. A few loose hairs also fell on each side of her chin that she brushed away with one hand.

Coughing profoundly, she felt her vocal cords changing as well, slowly sounding more feminine, womanly, and seductive with each passing second. She swear her adoptive parent will be shocked by her new looks, but given that reality was reshaping itself with each transformation, Futaba wasn't so sure if he even recognized her or if her adopted guardian even exist at all!

Whatever the case, she has to focus on her transformation as she approaches adulthood. Her childish feature, already a distinguishable aspect of hers, was now shifting into something more appropriate. Little by little, her face began taking on an oval-shaped structure similar to an anime character's, though it looked unique to her as she can tell that it was not exactly an exact match to any particular person's face.

Her eye sockets gradually became deeper and darker as well. In turn, her irises turned dark brown while the whites of them remained light blue, giving her eyes a slightly eerie yet sexy look. They're not quite black like most people would assume, but she likes how it makes her eyes stand out more than ever.

The last thing she noticed is how her skin tone started turning pale as well, becoming lighter than snow and matching almost perfectly with the rest of her body. This was a very pleasant surprise as far as she was concerned because it gave her complexion an overall whiter hue. Her hair color changed along with it as well, becoming more of a blonde shade as well. This was especially noticeable on the tips of her bangs which turned blonder than before and fell across her forehead.

Lastly, as her transformation reaches its climax, Futaba, or at least what remained of her now that looks like an entirely different person, noticed something about her slowly-maturing voice. Her accent was sounding a bit thicker than usual, becoming less Japanese and more like... an American?

Now that she thinks about it, she was now getting more fluent in English, with any sort of semblance of her Japanese heritage becoming non-existent.

The last touch of her physical changes came in full force, with her chest growing visibly larger than it did before. This was mostly attributed to the growth in her bust size that resulted in a larger proportion of her figure while also giving it an overall fuller look and feel.

She's not quite sure if this is how her breasts would normally grow when she reached maturity, but it certainly does appear this way based on what she experienced with this one-woman experiment that was supposed to be harmless after all. The only problem with this is that she may have gone overboard...

Looking back, she saw what looks like an adult woman with a lighter complexion, a lush head of blond hair, a pair of brown eyes, and a figure that would make any other females jealous, with little hints of her Japanese heritage, and even that is slowly changing as well.

With each passing moment, her face slowly reshaped itself into that of an American woman, language, accent, and all. Her eyes are now more oval-shaped, with defined eyelashes emphasizing its now sapphire eyes, and her eyebrows are now thicker as well as darker while curling upward. Her hair color shifted to a natural golden blonde shade, giving it a more natural look to it as they now hang down over her forehead to cover a portion of it.

Any semblance of herself, as well as her Japanese heritage, is now gone, for it was now replaced by an entirely new form and personality as if they never existed at all. "Fuck..." She whispers to herself under her breath. "...this is crazy."

The woman's face is now more oval-shaped than before, her facial bones looking more refined and defined as her cheekbones are now prominent and visible above her forehead. Her jawline is sharper and straighter as well while its contours have become more pronounced. She's starting to look a lot more mature than before! Her forehead is now more narrow but wider than before as well.

To finish off her transformation, Futaba, or at least someone who once resembled the 15-year-old hacker moments ago, felt somewhat more confident than ever, as her old personality was now akin to that of a typical rich American woman who enjoys the luxury that comes with it.

And she was proud of it.

Coming out of the bathroom, Futaba was now in an expensive hotel suite, usually the ones used by rich people and other influential celebrities, and was visibly surprised by the sight of it all, as if she belongs with the rich. Looking back to the bathroom, it was now aesthetically different, save for a custom-made smartphone that she just used a while back.

A new setting pops up on the app, in which you can now input a new name for the user's new form, along with all other settings in the "Mental Change" options.

Futaba took a deep breath and entered a name different from her own: "Alicia Beatrice Trevors". Upon pressing the "Applying Changes, her mind went into overdrive as her memories began to jumble and shift with all the new memories that slowly overtook her. The best thing she can only do is to accept who she becoming, knowing that there's no turning back before her mind went blank and passes out.

The woman wakes up and remembers something...

From her birth to her childhood, she remembered everything as an American girl, born to an affluent family of wealth, fame, and power that were known around the world.

She grew up in an elite private school where she learned all about politics and the ways of society from a young age. Growing up, she was surrounded by beautiful girls that could have easily been models for major fashion brands or even famous actresses. Now 27 years of age, those days are long forgotten as she was now much prettier than before, both inside and out as she uses her wealth and influence to help those in need through her charity work.

In her heart, mind, and soul, she was not Futaba Sakura. She was always been Alicia Beatrice Trevors, and always will be.

Her transformation is finally over.

Coming to her senses, Futaba, or rather Alicia as she was now known, was slightly confused. It was night-time and everyone else has partied in the party suite on the top floor, yet here she was on the floor, confused and naked for reasons she cannot remember.

The Realizer Suitcase opened up, startling the woman, and revealing a sparkling red dress. A slit down the side allows for a view of her cleavage, while a subtle curve at the rear gives a peek at her butt as well. Her shoes, a pair of high heels with three straps across the back of her calves, and small ankle straps to hold them tight, accentuate her legs nicely.

And then there was the jewelry. There was a pair of dangling earrings and an equally large necklace of diamonds that made her look like a million bucks.

Dressing up, Alicia looks like she was dressed to kill, with her attire complimenting her curves perfectly. She's now a blonde bombshell with curves to die for.

"Wow..." She murmurs to herself softly. "I'm so pretty." She takes a step forward to admire herself in a mirror that hangs near the entrance of the room.

Ready to have the best party of her life, Alicia walks into the room to greet her friends and acquaintances who came along for this extravagant affair. She is dressed like a celebrity. With her long platinum blonde hair and golden tan skin, it would be hard to not recognize her as the most popular person in attendance, especially if anyone were to see her face up close.

She was the center of attention, making any other person feel like they could blend right in as she glitters from all angles with glittery, sparkling makeup and makeup red lipstick that perfectly complemented her complexion.

Looking at her from head to toe, everyone else can't help but feel like they're staring at an actual Hollywood starlet in her prime. It almost feels like she has come back to life.

Her cleavage, already visible in her revealing dress, was even more pronounced now as her bust expanded to fill out her body to its full potential while also giving it that extra bit of oomph. Her hips and rear were noticeably larger as well, resulting in her curvy figure becoming even curvier than before. Her hips are now wider, her ass bigger, her legs slightly thicker, her shoulders are more pronounced, and her arms are toned.

Her eyes and skin color remained the same while her hair is now slightly lighter than before as she was able to pick her favorite shade of blonde to suit her needs.

Overall, it is an all-American package!

As she partied through the night, it became clear that transforming into Alicia Beatrice Trevors also erases the very own existence of her life as Futaba Sakura, allowing her to completely live out the rest of her life as a whole new person under a different name with all new memories that never existed in the first place, leaving nothing for her past self to cling onto as she becomes someone different from herself under a fresh identity that is all her own.

The woman is now Alicia Trevors, an influential American philanthropist whose fame knows no bounds thanks to her work as an actress and model, a politician, and a successful entrepreneur who is now known as one of the richest women in America due to her many businesses and investments around the country.

It's been ten years have passed, and Alicia Beatrice Trevors has been doing great with her life, now having no lingering memories of her past life as Futaba Sakura, who she dismissed as a mere memory from before she met her current husband and lover, Keith.

They have two children together: a daughter named Michelle and a son named Chris who currently attends college. As of right now, Alicia's life appears to be complete with love, wealth, and family. She is still very much loved by her husband and adored by her children as well.

For her, this is the best life she ever had, and she wouldn't have it any other way!

----

Futaba Sakura woke up one morning, the smell of vine still drenched in her body. From what she recalled, she became Alicia Beatrice Trevors and have a wildest party of her life. Anything else was so much as a blur that she cannot remember anything else.

Whatever it is, one thing is for sure: that app opened a whole new possibilities for her, and she can only smile for it.
