(Izuku Monster Ninja Girl) Nagisa's Reality Rewrite Draft

“Oh my lord~ Is that really you, the legendary hero Deku from U.A. School for Heroes?!? I have heard so much about you!“ I declared with fake enthusiasm, running up to the boy with a block in my hand, giving him the widest smile I could.

“L-Legendary…? I wouldn’t exactly call me legendary…“ he sheepishly replied, scratching the back of his head.

“But you are! At least to me! May I have your signature? I am your greatest fan!“ Again, my acting skills are really shining through.

“Sure.“ He said, taking the pen from my hand and giving me a signature on the block. To which he then smiled and asked me back. “And may I also know who my greatest fan is exactly?“

“Certainly~“ I declare, this time with genuine glee as I pull out my reality marker. “I am Nagisa Fulkami, Goddess of darkness. And I am happy to add to your Signature~“ And so I wrote on the block above his signature.

<I, Hero Deku, hereby declare that I will transform into whatever Nagisa commands me to, with no one realizing those changes except for Deku himself.

Signed, Deku>

A faint dark aura emanated from that piece of paper, before vanishing completely, with me giving him a mischievous smile because I knew I already won.

Deku's eyes widen as he reads the newly-added text, his face paling. "W-what? What did you just do?" he stammers, looking from the block to me with growing alarm.

I giggle, twirling the reality marker between my fingers. "Oh, nothing much. Just a little divine intervention to make our encounter more... interesting."

With a flick of my wrist, I point the marker at Deku. "Let's start with something simple, shall we? Deku, I want you to be a mature woman, maybe around the age of 25. That sounds about right."

Deku's eyes widen in horror as his body begins to shift and change before my eyes. His short, messy green hair lengthens and cascades down his shoulders in elegant waves. His face softens, cheekbones becoming more pronounced as his jawline refines. His chest swells outward, straining against his hero costume as his waist narrows and hips widen.

In mere seconds, where the boyish hero once stood, a striking young woman now gapes at me in disbelief. Her emerald eyes, still unmistakably Deku's, brim with confusion and panic.

"W-what... how..." she stammers, her voice now a smooth alto. She looks down at her transformed body, hands trembling as they explore her new curves.

I can't help but cackle with delight. "Oh my, don't you look lovely! But don't worry, dear Deku. This is just the beginning of our fun!"

Deku's face flushes crimson as she tries to cover herself, the hero costume now ill-fitting on her new form. "P-please, change me back!" she pleads, voice quavering.

"Now, now, where's the excitement in that?" I tut, tapping the marker against my chin thoughtfully. "Let's see... how about we add a dash of the extraordinary? Deku, I command you to become very bottom heavy! Each of your cheeks should be wider than your shoulder width and your thighs should be fittingly large to boot."

Deku's eyes widen in horror as her body begins to morph once again. Her hips suddenly expand outwards at an alarming rate, stretching the fabric of her costume to its limits. Her thighs swell and grow, becoming thick and muscular. In mere moments, her lower half has ballooned to absurd proportions.

"Oh no, oh no," Deku whimpers, stumbling as she tries to adjust to her new center of gravity. Her enormous bottom and thighs wobble with each movement, threatening to burst through the straining material of her hero outfit.

I circle around her, admiring my handiwork with a mischievous grin. "My, my, how wonderfully extravagant! I bet you could crush villains between those thighs now."

Deku's face burns an even brighter shade of red as she attempts to cover herself, but her new proportions make it nearly impossible. She wobbles precariously, trying to maintain her balance.

"This is... this is too much!" Deku protests, her voice a mix of embarrassment and frustration. "How am I supposed to be a hero like this?"

“Hehehe~ You’re right~“ I giggled, causing a cold shower to visually run down Deku’s spine. “That’s because you are no hero. I command you to be a Ninja girl in a skintight outfit, and when you next see a person that is not me, you will remember that for the last ten years, you have been their loyal bodyguard and protector and they were your master.“

As soon as the words leave my lips, Deku's form begins to shift once again. The hero costume melts away, replaced by a sleek, black bodysuit that hugs every curve of her new figure. It seemed to fit especially snug around her expansive behind, which to her dismay.

Deku's eyes widened in shock as she took in the ridiculous outfit. "W-what's happening to me?" 

I circle her, admiring my handiwork. "You look perfect, my little ninja. Now, why don't we test out the main part~?"

As if on cue, a Momo Yaoyorozu rounds the corner, completely oblivious to our presence and heading towards the Academy. Deku's eyes widened even further, her head suddenly throbbing with an onslaught of vivid memories. A decade of loyal service crashes over her like a tidal wave, leaving her gasping and clutching her temples.

She remembers the day, ten years ago, when a young Momo saved her from a group of ruthless bandits. The gratitude, the sense of purpose, the vow of eternal loyalty - it all floods back with startling clarity. Countless nights spent guarding Momo's bedchamber, silently dispatching would-be assassins before they could harm a hair on her mistress's head. Days spent in the shadows, always watching, always protecting.

The memories cascade faster now - training sessions where Momo helped her hone her ninja skills, quiet conversations under starlit skies, shared laughter over inside jokes. She recalls the pride she felt when Momo praised her skills, the fierce protectiveness that surged through her veins whenever danger threatened.

Without hesitation, Deku springs into action, her new ninja reflexes kicking in. She leaps gracefully through the air, landing silently in front of Momo with catlike agility.

"My lady," Deku breathes, dropping to one knee and bowing her head. "Forgive me for startling you. I was merely ensuring the perimeter was secure."

Momo blinks in surprise, but there's no hint of confusion in her eyes - only warm recognition. "Deku, my faithful guardian. You never cease to amaze me with your dedication."

I watch from the shadows, barely containing my glee as Deku seamlessly slips into her new role. The once-bumbling hero now moves with fluid grace, every gesture screaming deadly competence, even despite her buttcheeks standing out behind her more than a shelf and wobbling more than water balloons. Only Deku could pull that off.

This was just too good to let go, so I turned myself invisible and started following them, already thinking about my next command. Deku was astoundingly perseptive, likely noticed my presence immediately again, but it didn’t really matter. I was ready for the next command and she wasn’t.

“Deku is a Monoeye. She also doesn’t have hair, only a lot of long and thick braid-like tentacles that end in eyeballs, because Deku is a far descendant of the monster girl race known as a Gazer.“

Deku's two eyes meld into one large, piercing orb in the center of her forehead. Her silky black hair writhes and twists, transforming into a mass of writhing, braid-like tentacles. At the end of each tendril, a tiny eyeball blinks open, darting around curiously.

"My lady… Hnn…” Deku freezes mid-sentence, her single eye widening as the sensation of the transformation takes hold. The tentacles writhe and squirm, each eyeball at the end blinking rapidly as they adjust to their new existence.

Momo turns, concern etched on her face. "Deku? Is everything alright?"

“N-Nothing. My eyes… my eye just…” Deku moaned, though luckily for her it was starting to calm down. Although Momo just seems to giggle at her. 

“Your Eye? Which one? You have like a docent~” Momo joked, and Deku finds herself laughing along with her Mistress.

"Forgive me, my lady," Deku ultimately says, shrugging her shoulders. "I was momentarily overwhelmed by my… uhm… new range of vision."

“New range of vision?” Momo asked while still giggling. “Girl you have had around twenty fives eyes for as long as I know you, and I have known you for a really long time~ What could possibly expand your range of vision now~?"

Deku nods, her tentacle-hair swaying hypnotically. "Indeed, my lady. I guess I was just feeling a little more under the weather than I expected."

As they continue walking, Deku's multiple eyeballs swivel independently, scanning the area quite attentively. Her single main eye remains fixed on Momo, vigilant as ever, while continuing their small talk as they always do.

I trail behind them invisibly, barely containing my giggles. This was too entertaining to stop now. What other outlandish transformations could I inflict on the former hero? Maybe a little bit of a personality tweak~

"Deku has a habit of swaying her butt more than she needs to with whatever she is doing. She also can only stand still in poses that emphasize her butt. She now also no longer has a concept of personal space, so she tends to always get way too close to everyone.”

As if on cue, Deku's movements suddenly shift. Her hips begin to sway dramatically with each step, her oversized posterior swinging from side to side in an exaggerated fashion. Even when she pauses to scan their surroundings, her stance changes - one leg cocked, bottom thrust out provocatively.

"My lady," Deku purrs, her voice taking on a sultry tone. She sidles up to Momo, pressing uncomfortably close. Her tentacle-hair brushes against Momo's arm as she leans in, her single eye mere inches from Momo's face. "I wanted to tell you that I sense no immediate threats, but I must insist on remaining in close proximity for your protection."

Momo smiled painfully, clearly used to Deku's change in demeanor, but doesn't step away. "I... appreciate your dedication, Deku. Though perhaps you could give me just a bit more space?"

“Ah, yes. Of course.” Deku's single eye widens, her tentacle-hair writhing as she shook her head. "Then let’s make ourselfs to class like we usually do, shall we?" She presses even closer, her exaggerated curves brushing against Momo.

I have to stifle a laugh as I watch Momo's ‘I give up’ expression. This is too delicious. Time to up the ante.

"Deku now has an overwhelming urge to dramatically pose every few minutes, striking ridiculous superhero-style poses that emphasize her new physique," I whisper, doing my best to hide my giggling.

Suddenly, Deku leaps back from Momo, striking an exaggerated pose. Her single eye narrows dramatically as she places one hand on her hip and thrusts the other skyward. Her tentacle-hair whips around her head like a writhing halo, each tiny eye blinking rapidly.

"Fear not, my lady!" Deku declares in a booming voice. "For I, your loyal Gazer guardian, shall protect you from all harm!"

Momo slaps her face with her hand, as Deku holds the pose for several long seconds before relaxing. Momo moans. "Deku, why now…?"

But before she can finish, Deku is already moving again. She slides up next to Momo, pressing close once more. "Because as a Hero it's important to make your entrance known," she purrs, her exaggerated bottom swaying hypnotically. "Danger lurks around every corner and so do fans. You never know who might listen in on you…”

Like me. I thought I had seen the best of it, but this was truly hilarious. But I was ready to explain something away with my next command again.

“Deku is also part succubus, so she has devil-like horns and Bat-like wings. And while she isn’t all that interested in regular succubus activities, it is widely agreed that the reason why she moves like that and has this unrealistic butt is because of her succubus heritage.“

And her body immediately responds to my command, as Deku's form shifts once again. Two curved horns sprout from her temples, gleaming obsidian in the sunlight. Enormous bat-like wings unfurl from her back, stretching wide before folding neatly against her body.

Momo leaned backwards, dodging Deku’s wings from slapping her face. "...could you please watch a bit more who you are slapping with those things?"

Deku blinks her single eye, then reaches up to touch her new horns. "Ah, yes," she purrs, her voice taking on a confused but sultry undertone. "I am sure to do that. I just wasn’t expecting… those wings… to be there." She steps a bit away from Momo, stretches languidly, her wings fluttering and her exaggerated curves swaying even more pronouncedly.

"Of course…" Momo shook her head. "Because obviously that behind of yours and those wings of yours have only grown yesterday. Seriously, are you okay? How can forget someone that they are part succubus and part Gazer?"

Deku strikes another dramatic pose, wings spread wide and tentacle-hair writhing. "Uhm… Indeed, my lady! I would never be able to forget that! As true as I am your Ninja!" She punctuates this declaration by wiggling her oversized bottom.

Momo facepalms. I have to clamp a hand over my mouth to stifle my laughter. This is too perfect. But why stop here?

Those special powers of theirs were called Quirks, right?

“Deku’s quirk is the power to detach and make float any of her tentacle eyes, at the cost that she is frozen is a sexy position until she is a complete person again.“

As if on cue, Deku's body begins to shiver once more. This time, nothing specific happened, so Deku just looked sort of confused. Momo immediately noticed, and just sighed at her. “What now? Feel like posing again?”

"My lady. Do I… do I have a quirk?" Deku exclaims, her voice slightly higher pitched as she looks at her hands. "I feel like I…"

Before she even finished her sentence, three of her eyes from her tentacles separated from her body, floating up high and giving her a point of view she could only dream of before. This was a spies wet dream ability, able to keep eyes on everything and everyone at the same time. Until she noticed what was happening to her own body.

Below, Deku's body remains frozen in place, hips cocked at an impossible angle, her enormous posterior thrust out provocatively. Her legs are locked in a pose that can only be described as "aggressively seductive."

“Haa…” Momo sighed, leaning against the posing Deku as she just continued to shake her head. “Are you telling me that you forget about that too? What’s with you today? Could you at least go into spy mode when we are not in the middle of the street where tons of people will admire your butt?”

“I… I apologize. I guess I got too excited.” she said, slowly making her eyes return to her tentacle hair. Which then finally allowed Deku to move her body in ways that were… less explicit.

Momo pinches the bridge of her nose, clearly fed up with Deku’s attitude. "Deku, perhaps we should reevaluate this whole thing. I really don’t think that you are suited to be a ninja if I am honest…"

That’s when I nodded and got ready to give the coup de grace to Deku, locking her in for her new perfect life.

“Deku just acts the way she does to look incompetent. In reality Deku is the best and deadliest ninja the world has ever seen, and Momo knows that. When they are out and about, Deku does her weird things. But when she is on a mission, then there are no weird traits and Deku is unbeatable.“

As if a switch had been flipped, Deku peeked up in an instant. Her single eye suddenly seemed laser-like focus, and her body language shifts from exaggerated to extremely precise. So she took a few steps forward, her butt still swaying unnaturally much.

"You know how it goes. Those who are underestimated… win the fights.," Deku says, her voice now a low, dangerous purr. "That said, I have just noticed that we are being watched."

Momo's eyes widen with a worried but ready expression. "Who? Where? Do you have eye contact?"

With lightning speed, Deku suddenly produces a handful of shuriken, her tentacle-hair eyes swiveling to scan every direction at once. I was impressed, realizing my invisibility may not be enough to fool Deku's enhanced senses.

"Stay close, Lady Momo," Deku instructs, her voice low and serious. Her bat-like wings unfurl silently, ready for action. "Our observer is skilled, but not skilled enough."

In a blur of motion too fast for the human eye to follow, Deku launches herself into the air. Her tentacle-hair whips out, each eyeball searching independently as she throws out some shurikens at my exact location. And they hit the ground… because I teleported away. I am always so impressed at how good these transformees become in the end.

“…they're gone. And I don’t know where.“ Deku scanned the area for a little while longer, before ultimately shrugging her shoulders. “Meh~ It’s not like they stand a chance against the great me anyway. Am I right, Mistress~?“

Momo nods, a mix of admiration and amusement in her eyes. "Indeed, Deku. Your skills never cease to amaze me."

Deku preens at the praise, her single eye gleaming with pride. But just as quickly, she shifts back into her exaggerated, clumsy persona. Her hips begin to sway dramatically once more, and she strikes another ridiculous pose.

"Oh, my lady!" Deku exclaims in an overly theatrical voice. "Your words fill me with such joy! I must express my gratitude through the art of interpretive dance!"

She begins to gyrate wildly, her tentacle-hair whipping about, wings flapping erratically. Her enormous posterior bounces and jiggles with each exaggerated movement.

Momo sighs, but there's a fond smile on her face. "Deku, perhaps we should continue on our way. Your... interpretive dance is drawing quite a bit of attention."

Indeed, passersby have started to gather, staring open-mouthed at Deku's bizarre performance. Her single eye swivels to take in the crowd, and she seems to preen under the attention.

"Of course, my lady!" Deku exclaims, striking one final dramatic pose before sidling up close to Momo once again. "We mustn't delay your important business. But fear not, for I shall remain ever vigilant!"

As they continue walking, Deku's movements oscillate with ridiculous exaggeration. Momo knew she was still probably the most vigilant person on earth, although with the way she was wiggling her oversized bottom, you really couldn’t tell. But that only really hammered home the one thing Momo realized was truer than she expected.

…Deku’s act, regardless of how ridiculous it looked, did kinda work…

Sometimes you just want to have fun with a hero. And sometimes that involves turning him into a loyal ninja monster girl. As one does.
