Curse of the Were Miku (TG Commission)
Added 2025-05-16 17:54:41 +0000 UTCGrey breathed a sigh of relief as he sat down in his apartment, totally exhausted from a full day of socialising at his local anime con. It had always been a highlight of his year ever since he got into cosplaying and collecting stuff from Japanese media, but it also always managed to leave him totally drained in the aftermath.
It made for a nice break from his average everyday life though, a few days where he could forget his struggles and stresses, including his boring, soul-crushing job, as he indulged himself in his hobbies. He had even managed to pick up a few figures and manga volumes, even a CD of someone’s remixes!
His shoulder ached from the last thought, Grey rubbing the red scratch marks that had been left behind from a strange encounter he’d had at the convention. It was just after he had bought the CD; he had been walking to the next stall when he saw them, a group of Hatsune Mikus.
They were chatting away lively, all smiling widely. Some were in project voltage outfits, others were wearing other outfits like kimonos or dancer outfits, but they were led by one in her classic, iconic clothes. It was amazing, they all looked identical! And there were at least ten of them grouped together. Grey was sure he would have noticed flaws in their cosplay if he’d looked closer, but from his brief look they were easily some of the best cosplays he had seen.
But that wasn’t even the most impressive part! He’d heard them talking, and he could actually hear Miku’s famous artificial voice leaving all of their lips! It wasn’t a hard voice to replicate normally, but he had never seen it applied so easily in an actual cosplay; he had to know more! Despite normally being a somewhat shy, reserved person, Grey had been too curious and interested for his own good, managing to gather the courage to step forward and speak up.
“Um, hi!” He’d awkwardly managed to get out as he approached the group, the girls looking up at him in interest. Well, aside from the ice type Miku who seemed content to give him a piercing glare fitting for her element (was that hair real crystal? If so, that couldn’t have been very comfortable to be wearing on her head…)
“Yes?” the ringleader answered, Grey almost unnerved by the artificial sound leaving a human's mouth, “May we help you?”
“Right, yeah! I was just wondering how you did that with the Miku voice? It’s really impressive!”
“With the...?” The girl seemed confused for a moment, before the penny dropped and a smug grin filled her features. “Oh! Well you know, stuff~.”
They giggled in unison, as if to a joke only they got.
“Um... ok?” Grey blinked, feeling very lost in the conversation. “Well it’s fine if you don’t want to tell! Every cosplayer has their secrets and all!”
“Oh don’t be like that~!” The Dark type Miku giggled with a sensual smirk.
“Yeah, we don’t mind sharing~!” The dancer Miku added with an animated twirl and a wink.
“It’s really no trouble at all~! Just an... inside joke amongst Mikus~!” The original laughed. “You’ve gotta come in close thoughhhhh~.”
At the time he hadn’t really noticed she had used the word “Mikus” instead of “friends”, or seen any reason to be concerned about her odd, specific request. He instead just rolled with it and leaned in close to their leader, who despite being a head shorter than him, seemed to have all the power.
Grey didn’t see the crazed look in her eyes and flash of teeth, but what he did feel was a sharp pain as long blue fingernails slashed his exposed left shoulder. He swore and screamed, the Miku’s simply cackling in their artificial, cute voices as the leader smirked and said, “Oops~.”
They scattered with a chorus of snickers and giggles before he could ask for an explanation, dispersing into the crowd and vanishing from sight, one Miku in concert gear shouting back, “See you later~!” as he hissed and cursed at them.
“Fucking weirdos...” he grumbled at he recalled what happened, rubbing the scar that girl had managed to leave behind. If he didn’t know better he’d say it looked more like a wolf or bird had attacked him instead of some weird Miku cosplayer.
That and how tired he was remained the only downsides to the convention though, and hadn’t impacted his enjoyment too much in the long run. But it was also just as good to relax after such a long day, and that was something he was fully intending to take advantage of, even though the clock would be hitting midnight in only a few minutes.
Still, he was quite used to staying up late, so that fact barely crossed his mind as he got some YouTube videos ready to watch while talking to friends over Discord. He hummed while getting it all set up, and it took him a minute to realize he had instinctively pulled up “World is Mine” as the song. He guessed he just had vocaloid stuff on the brain from the cosplayers earlier, deciding not to question it. Ready for a night in, he headed to his window to shut the curtains, glancing up at the night sky in the process. And then his eyes locked onto the shining full moon.
It filled his entire vision, consuming his world. All else faded away, tunnel vision focusing onto just the moon and nothing else. Even the sounds of the city outside, the music playing, all faded away into dull, muted beats. His body froze. His mouth fell open. He shuddered. He couldn’t look away, forced to just stare at the glowing celestial body, transfixed by the moonlight. His phone slipped from his fingers and clattered to the floor, the scar on his shoulder burning with renewed intensity as it took all of his willpower to tear himself from the sight, stumbling back as he barely kept from falling over.
“What the fuck was that?” he whispered, feeling his heart pound, his body breaking out in a cold sweat as his head burnt. Did he catch something at the con? But stuff like that didn’t just break out all at once!
“Something... something’s wrong... something’s really fucking wrong...” he whispered to himself, his eyelids heavy as each beat of his heart felt as intense as a war drum.
He could swear there was a pressure, a weight building inside him alongside the steady rhythm, but the burning on his arm was the most intense of all. His cock throbbed and hardened in response to his bodily rhythms, the poor doomed man swearing and grunting as he pulled up his sleeve to survey what was happening to his wound.
He had expected bleeding, maybe for it to have spread slightly. What he was certainly not expecting was for it to have transformed into something different altogether. It didn’t look brutal at all, or even like a wound or scar altogether. Instead it was a tattoo, two numbers marked onto his body like a brand.
01
"H-How- how the fuck did that-!?" he began, before being silenced by his heart beating so hard it felt like it was threatening to burst from his chest.
He lurched over, swearing he was going to die, pressure building all over as it grew to unbearable heights. All the while the moonlight was continuing to bathe him, transmitting its command to his DNA, one it had no choice but to obey.
Become Hatsune Miku.
CRUNCH
Grey wailed in agony, falling to the floor as his back gave way, inches of his height shaved away as his spine shattered, shifting and shrinking in painful, precise pleasure. It hurt, it hurt a lot, but the man’s screams were just as blissful as they were pained, unable to get himself off all fours as he panted and grunted.
He was clutching onto his rug for dear life, the primal feelings inside him leaving him barely even aware that his back had changed at all. His fists clenched and unclenched, his watering eyes looking down in horror as his fingers shook in anticipation for whatever fate awaited them.
SNIK! SNIK! SNIK!
One by one they fell. Each finger burst with bliss as its intensity thinned out, its nail bursting out into a long blue talon. He screamed and sobbed, fingers tearing through the rug as his cock throbbed for more of the pain and pleasure alike. His hands shrunk, his muscles burning as any strength built up in his arms began to decay and wither away at a rapid pace.
It was too much, it was too fucking much, yet he had to deal with it all, Grey struggling to raise his head as his vision blurred from the tears. His phone was so close but he couldn't focus enough on it; all he could do was call for help in the feeble, vain hope someone could save him.
No one was going to save him. No one could anymore.
He belonged to Miku now, and nothing could change that.
"H-Help! Help m-meeeeeeeee! My body- MMMMAHHHHHH~!"
His throat felt like it was being torn to pieces by his talon-like nails, the man letting out blubbering, gasping chokes as his shoulders slammed down to fit the blueprint his body was being forced to follow.
The worst part was that he was also one wrong move away from cumming harder than he ever had in his life, his dick awkwardly throbbing into his strangely smooth and soft thighs. The pain in his throat was subsiding, instincts guiding him as he finally opened his mouth and,
"Sekai de ichiban~~..."
He blinked.
"W-Wait, why did I-? Oh god, oh my god, I s-sound like her! I sound like Miku! Why do I- KYAAHHHHHHH FUCKKKKKK YESSSSSSSSS~! OHHHHHHH I-IT HURTSSSSSS BUT FEELS SO MMMMMM~!"
The transformation gave Grey no time for further reflection, the sensations burning down his body as he let out a melodic, sing-songy scream of terror and anticipation.
This time he did cum, his eyes rolling into his skull as he wailed like a wounded animal, his ribs feeling like they were being crushed as he tore at his shirt, sobbing as he felt the first bone give in, then the next, before they all collapsed in a cacophony of crunches.
It was like a cage descending on his heart, which pounded hard and fast in a steady rhythm. He clawed at his own shirt, his body shrinking further as he fell onto his back and kicked wildly, feeling the beat of his heart echo through him. The beat of a song.
“Miku. Miku. You can call me Miku~.” The words tauntingly echoed through his mind, performed by that same smirking, smug Miku from the convention, swaying her hips and pushing out her chest with each and every syllable.
“Blue hair, blue tie, hiding in your mi-nddddd~.” He was screeching as his sides collapsed, crushed away by idol expectations into shapely, alluring curves as he came again from the painful shift.
He could hear his voice, her voice now, screaming and squealing, that inhuman, feminine, electronic soprano that made every sound melodic; it was breaking his brain but he had no choice but to accept it. Grey was finding it hard to think in general, thrusting his chest upwards and wailing in bliss as each movement sent another deposit of fat rocketing behind his eager nipples.
Each thrust was making them rise, his hands upon them as he sobbed in delight, his body alight with feminine, vocalised bliss. He dug his fingers into the soft fat, his body twitching to the rhythm, wriggling his hips in a desperate dance as Grey fought to stay focused in this fever dream-like state.
“Miku Miku, what's it like to be me? Grey, Grey, looking in the rear-view~. Grey, Grey being thrown away~!” The singing was mocking him, the Miku dancing in his mind’s eye pulling down her own and sticking out her tongue tauntingly.
Grey was sinking into the Miku quicksand; the more he struggled the faster his mind fell to the brainrot that festered in the minds of so many. His self control had already taken a major blow as he smushed his c-cup boobs into the floor, his memories decaying from the idol’s corruptive touch.
Conversations, friends, family, his entire life was falling victim. Why did any of that useless stuff matter? Hatsune Miku didn’t need those things. She was an idol, an icon! More than even a brand or product!
“M-Mikuuuuuuu~???? Miku is l-lifeeeeeeee~!!!!!! Miku~! MIKUUUUUU~!!!! YOU CAN CALL ME MIKUUUUUUUUU~!!!???” he sang, screaming in pleasured agony as the pressure in his hips reached the breaking point.
CRUNCHSHATTERCRUNCHHHHHHHH~!!!!
“AHHHHHHHEEEEEEEE~!!!!!! KYAHHHHHHHHHH~!!!! N-NOOOOOOOOO~!!!!” he wailed, clutching his head as his hips painfully widened, shimmying to the beat as Grey sobbed from the effort to stay afloat. “I don’t- I DON’T WAHHHHHHHH~!!!! MY HEAD~! SHE WON’T- SHE WON’T SHUT UPPPPPP~!!!!”
“I'll take you to where you've never been~. And never bring you back again~.” The mental Miku shimmied and giggled, Grey whimpering in half hearted resistance as he reluctantly mimicked the smug idol.
What he wanted was irrelevant; the transformation couldn’t be stopped, and deep inside he knew it, he knew that even when the sun rose the concert that had begun in his mind would continue 24/7 for the rest of his life; there was no going back once you went Miku. He could barely remember his name, or anything about himself, like he was trying to focus on a test with someone blaring their music as loud as they could right next to him.
“My nameeeeee Grey! Grey whahhhht????? Hatsune???? Griku? But you can call me MIK-OH GAWD NOOOOOOOOOOOO~!!!!”
He was losing the battle and he knew it, unidol-like curses slipping from his lips as his stretched feet slipped free from his shoes, the socks following suit while his feet crunched and shattered down into dainty, feminine perfection, his tiny toes curling in bliss as his eyes sparkled.
Miku’s influence was corrupting him, his brain letting it all in even if his soul didn’t want it (or maybe even it did at this point), the idol's influence totally overwhelming his mental defences. He ran his hands down his wide, alluring, sexy hips, unable to stop the smug smirk covering his face in return.
It felt right to sound like this. To have such deep curves and wide hips. To savour the unrivalled sensation of becoming Hatsune Miku. Everyone knew her. Everyone wanted to bask in her glory. But most of all, it felt amazing to just keep thinking Miku~.
“OOOOOOOOOO EEEEE OOOOOOOHHHHH~!!!” he half sang and half yelped as his legs bones crumbled, snapping and cracking into new, slimmer forms as fat rapidly drained away, his strength abandoning Grey to his fate.
“If you forget, you’ll fade away~. I’m asking you to let me stay~.” Miku asked kindly in her song, her perfect smile gleaming like the moon as the man gurgled and giggled in the voice of his idol, of perfection herself. He couldn’t focus on the how or why, all he wanted was the more.
And more he got, the moonlight washing over his clothes as his shirt was bleached white, his sleeves separating as they became black and spaceless. A tie settled between his fat, sensitive tits as his pants popped into a tiny, thigh-length skirt, his tiny feet soon covered by his new thigh-high boots.
Grey should have been more alarmed at such a development, but his sense of self was falling apart at the seams, the base instincts of a vocaloid taking over, a wide smile filling his face as his erect cock throbbed into the unbearably soft fabric of his skirt.
Now dressed as his idol, on the verge of perfection, there was only one thing for the pleasure-addled mess to do.
“I’m thinking Miku, Miku~! OOOOOOO EEE OHHHHHH~! MIKU MIKU~! NO MORE GREY~! B-BATHE ME IN YOUR MAGIC LIGHT~! KEEP IT ON IN GREYEST NIGHT~! I NEED YOU HERE TO KEEP ME STRONG AND MIKU~! TO LIVE MY LIFE AND- AND- KYAHHHHHHHHEEEE~!!!”
He sang in delirious delight as he slammed his thighs together, his whole body bucking with each surge of mass that pumped into them. The cool air rushed against them as they swelled, bulging from the boots, fattening drastically for the world to see, growing into perfect idol pillows that fans wished they could rest their heads on, while also being strong enough to crush a watermelon between their heft.
Grey was getting a firsthand demonstration on that front, his balls proving to be a suitable stand-in as the pressure grew to unbearable levels. The painful pleasure peaked once there was a wet SLURK, then another, Grey giving a soprano-worthy howl as they were crushed into ovaries.
He came out the last of his seed with gusto, the man in shambles as his world spun and burnt with an onslaught of overwhelming sensations. Grey was so far gone he simply accepted it; his world was Miku’s, everyone’s was, she could do whatever she wanted and nobody could complain!
She was consuming every thought with her alluring siren song, Grey barely present as he moaned the name of his idol, his obsession, his goddess over and over as she hollowed out his mortal shell and made it his own. He knew he would be discarded, cast aside into nonexistence to make room for Miku, but he no longer even cared, more than willing and eager to sacrifice himself for his precious vocaloid goddess.
“I’m waiting for you, I’m wide awake~. Your expensive poison snake~.” Her words coiled around his decaying mind, squeezing everything he was out faster with brutal efficiency. Such decay triggered one of the most important parts of his Mikufication, his plain, short black hair blossoming into something truly beautiful.
It cascaded down like a waterfall, consumed by the most perfect shade of light blue imaginable, the colour itself purifying every uncared strand and locked into flawless softness. It was like touching a cloud, the locks spreading out all around Grey as he looked down at himself in barely contained bliss and excitement, the sight of the idol's perfect body only making him wish he could be changed faster.
And luckily for him, Hatsune Miku never turned down her fans' requests.
He could feel it rush into his rear all at once, the electronic, sing-songy moans showing Grey’s approval as the inflating cushion rose him up from the floor. The thick, spongy fat sensually squished into the ground, and it just seemed to keep growing, determined to become a worthy partner to Miku’s world famous hips and thighs.
His cock experienced failed orgasm after failed orgasm, with no seed left to give to his idol. He whimpered between his giggly squeals as her thighs mounted more pressure by the second. His blue hair was styled by invisible hands, as if the famous Miku twintails were a genetic requirement for anyone who bore her name.
Each change was brutal, fast and pleasurable, hitting him like a truck with brutal snaps and crunches. They hurt too, but that was inevitable when letting go of the past, a similar onslaught of cracks and snaps hitting his face, eroding away his masculine features.
His nose painfully compressed into a small button, his teeth burning as they were aligned into Miku’s perfect smile, his lips swelling into soft, pleasant cushions. Even his eyes widened, his eyelashes fluttering as they gracefully lengthened outwards.
Grey didn’t need a mirror to tell it was Miku’s face, his joy growing to levels he didn’t know were possible. He loved this! He needed this! He needed his goddess to inhabit him completely! To erode his soul and self as she nestled inside her new curvy, fleshy shell!
“You found me here inside a dream~. Embrace the end, walk out as me~.” The mental Miku leaned in close, her influence coiled around his brain like a venomous snake, a dangerous glint in her eyes that Grey was none the wiser to. “One more time, Grey~.”
“I’m thinking Miku~! Miku~! OOOOOOOHHHHHHH YESSSSSSSSS MIKUUUUUUU~!!!” He screamed, providing the backing track for his own erasure as a tug hit his cock, his heartbeat pounding faster to the music. Miku was descending on her prey, seeping into his brain rapidly, her mere touch erasing every one of Grey’s memories with a very literal case of brain rot.
Her corruption was effortless, her takeover all the easier when the host was actively wanting it. Grey faded further by the second as his cock hammered itself deeper into him, his excited squeals reaching a fever pitch as he felt himself rot away into nonexistence.
The moonlight was shining upon his form as he felt his transformation reach its final stages, the man gurgling incoherently as Miku dug her influence deeper and deeper. He was being eroded and he loved it, unable to recall his name or life, only that he loved Miku, he craved her! He was hers, and as his cock continued to slide back inside him, he begged her to just erase him alre-
"Done~." Miku smiled for the first time with her new face, having erased Grey as casually as closing a window on a PC. "Miku was getting tired of that simping anyways~."
With that, Miku squeezed her thighs together one last time, letting out an eager cry of delight as her cock completely inverted, the idol cumming for the first time in her new body, kicking and screaming.
"YESSSSSSS~!!!!! FUCK YES~! KYAHHHHHHHHHHHHHH FUCK~! MIKU- MIKU LOVES THISSSSSSSSS~! MIKU- MIKU IS MIKU! MIKU IS HATSUNE MIKU~! AND THE WORLD- THE WORLD IS MIKU’S~!!!!!!"
She was left panting on the floor, a smug smile still on her face as she giggled in delight, the curse passed onto her by that fellow Miku at the convention having now fully consumed its new host. The new Miku couldn't be happier with this knowledge though, stretching with a sing-songy groan and giggle.
With that same smile on her face, she swayed her wide hips over to the balcony, humming one of her many songs all the while, taking a moment to admire the beautiful night sky she had been born under.
With her new form completed Miku giggled, browsing through her host's phone to check social media. "What was his name again? George? Greg? Gavin? Meh, Miku doesn't care. Why should Miku care about someone who’s gone for good~?" She giggled as a few messages came in from friends on Discord asking him why he’d stopped replying in the middle of a conversation, simply sending a winking emoji before closing the app.
She found what she was looking for right away, a selfie taken by a bunch of Mikus elsewhere in the city. To the normal person it was just a harmless picture of cosplayers hanging out, but to the new Hatsune Miku it meant something different; it was a calling card to anyone else who had turned to join them, and where to find them.
It was an invitation Miku took without hesitation, skipping out of the door without even caring to take anything with her. She could come back later and grab anything that may be useful to them later after all, but for now she had fellow Mikus to meet!
She wondered just how many variants they got this time! Granted, the most common thing for people to turn into was her classic look, but every once in a while they did get some of her many other variants! They usually grouped together around a standard one to avoid suspicion; it would probably be be a bit too on the nose and odd to have a stampede of identical Mikus in the same outfit walking around after all.
"Miku can't wait to meet the other Mikus~! I wonder how many we got at the con this time? It must be a new record! Maybe next time we can turn the whole con~! Speaking of turning, why even wait? The night's still young after all~!"
With that she skipped away, humming to herself with a sway in her step, hoping to entrance some potential Mikus on the way to meeting her fellow idols. And why shouldn't she? The world and all its people were hers, and she was intent to make the most of it~. Spying a couple walking alone together under the moonlight, Miku giggled, licking her lips as she headed towards the soon-to-be newest members of the group.
