Nikki had finished playing Outcome Memories as 2011 X using the Miku X variant, she's been playing for 3 hours and had fun chasing those survivors and now that she's tired out, she's giving herself a much-needed break. However, there is that one thought in her head that gave her something to do after maining 2011x in Miku X skin...having to cosplay as the original Hatsune Miku herself!

Luckily for Nikki herself, she has bought this Hatsune Miku cosplay set she got from the Internet about a week ago and she really wanted to try it since she listened to her songs and had recalled her appearance in Sega Games, and how she got this Sonic module for Miku in Project Diva.

"Well, this is it, after listening to people online in the comments below on my gameplay videos, It's my first time I'm gonna do this by...immersing myself in character..."

Nikki then confidentally said to herself as she grabbed the Miku Cosplay from the package box and she then starts putting them on, it started out by putting on a collared shirt with a teal tie with black and teal sepearated sleeves, a pair of a black skirt, black and teal socks complete with the black shoes with teal soles that matches the socks, a piece of a Miku Wig to go with a hairnet that covers up her entire brown hair, which has two red-hair ties to go over the long-length pigtails, and a pair of a replica of Miku's headphones...and finally when she takes a mirror to see her completly cosplaying as Miku herself, Nikki had finally outdone it herself.

"Hmmmm, not bad at all...though the top and bottom clothes seemed comfortable on me. I'm not so sure if I'm really gonna do this by myself."

Nikki said to herself again as she took a deep breath...about to immerse herself in character just like she said.

"Here I go..."

Nikki then shakingly struggles to pose...strikes a Cutesy, Idol-like pose and then said to herself in a cheery-tone of voice.

"I-I...I'm Miku!"

Nikki then smiled, thinking that she nailed at getting into character...but a little did she knew was that the "Miku Cosplay" seemed to be cursed and possessed by some Void Matter, in which once wearing this strange cosplay, it fully took over her body and using her as a host cause it was already too late for her to take it off now, as she felt her body glowing into a teal color...

"H-Huh?? W-What's happening?? A-Am I glowing or something? W-Why aren't they coming off?!"

Nikki then tried frantically and struggled to remove the wig, only for it to get stuck on her head to the point where the teal hair colors started turning entirely dark blue similar to Sonic's quills.

"No, no, no!! This is impossible! The costume's controlling me!!"

Nikki said to herself in horror as her body started shaking and twitching entirely, with her changed hair now resembling of Miku's but dark blue, she grew a set of quills resembling of Sonic's spikes as they grew bigger and longer, and hardened. Her headphones suddenly fell off of her head, revealing that her ears have gone pointy and it escalates to where they moved up and become a set of Hedgehog ears, blue patches of fur has sprouted on them. Nikki was about to panic but her body refused to, as she felt her face started to distort. Nikki grew a muzzle of a male, Mobian hedgehog with a black snout, causing her glasses to fall off again, her eyes then turned entirely black with blueish green pupils and white sceleras, dark blood then seeps out of her eyes and her teeth turned sharp and yellow.

Both of Nikki's hands grew bigger and masculine with claws growing on her fingers as a pair of white gloves manifested on both of her hands. Dark Peach-toned patches of fur then spread from her hands to her arms as they started to fuzz, Nikki groaned as she felt her arms bulged and grow with a set of masculine muscles, her shoulders have broadened with fur growing from shoulders to chest, she was becoming a bit...taller? As Nikki fell down to the floor, laying on her back, she then felt a bad cramp from her feet as the dark blue fur formed on her feet while her soles become dark-peach toned as they went all the way up to her legs, her toes have merged into six paw toes. They were growing bigger, but once they grew into a set of masculine paws, instead of her shoes tearing open by force, her shoes then changed into a pair of dark gray soap sneakers that looked like Sonic's shoes with her thigh-high cosplay socks shrinking down into a set of white socks.

"Everything I feel in my body while wearing this feels like wearing a tight costume that brings great pain...but why does it feel s-so great though?"

Nikki said to herself, secretly liking her changes, as she turned around to the ground gripping on the room floor with her hands and on both of her knees, she felt her spine arching into its manly posture complete with a dark blue Hedgehog growing out of her backside, peeking out of her Miku cosplay. Her waist had cracked along with her hips, becoming manly as her thighs then grew a bit plump though less feminine and more masculine with her legs bulking up a bit. Nikki then felt pain in her stomach as she clutched her torso, then, she felt a little pot belly expanding a little bit as she felt her grown gut.

"Holy shit...!!"

Nikki said in surprise as the dark blue and peach-tone fur reached from her chest to below the belt-line, her B-Cups shrunk into nothingness by force and then are expanding into a set of pectorals. A piece of chest-fur grew in between her swelling pecs, causing her to moan softly a bit, her shirt grew a bit tight that one or two buttons popped out...leaving a bare, exposed pectorals with no Bra. Nikki's feminine structure has become masculine as she felt an intense pressure that's applying to her crotch. The dark blue fur reached in-between her legs after the waistline as she felt it growing outwards, as this happened, she drooled and collapsed on the ground as she moaned in agony and arousal, her hormones, sex chromosomes, and reproductive system turned inside out, becoming an opposite gender. During Nikki's agonizing and arousing moans, her voice deepened and sounded sinister and masculine, though sounds a bit like Miku. The Dark blue fur finally reached down into her neck as it arched, a lump then had completely grew in her throat. With her panties becoming a pair of white-brieves, Manhood had finally had finally grew outwards from her crotch, rendering her as He/Him.

"G-Graarrrggh...T-That f-felt good...I...I..."

Nikki was unable to finish his sentence due to the physical changes he went through, he was panting on the floor, his mind started to fuzz and reset. He believe he was always Miku X, a variant and alter ego of 2011x, who is  a malicious creature born from dark matter, seeing Humans as nothing more than toys for him to use in his twisted games, being obsessive with Sonic the Hedgehog by taking form of the Blue Hedgehog hero, before capturing souls and torturing them for all eternity, and acts very short tempered and immature, throwing tantrums if people didn't play his game right. His kind of Ego when in this variant and Miku Cosplay acts like an archetype of a "Renowed, cheery, eager, and optimistic J-Pop Idol", but that was also an act just to tease and lure the others, even when playfully.

The transformation's finally complete as Miku X finally got up and looked at himself again.

"Not bad for such a God to pose as a cute-looking Virtual Idol. Hahahaha~!"

Miku X said as he cheers playfully, striking the same cutesy pose from earlier. However, one giant ring that leads him into "NOT PERFECT" where the survivors lead by Metal Sonic gathered here...recalling how he kill those survivors all the time, Miku X then gets an idea...

"This reminds me, I can't just stand around admiring myself for this cute-looking cosplay...I need more hapless victims too kill, not even that Scraphead's strong enough to overpower ME....Haha!"

Miku X smirked and giggled gleefully as he went inside the giant ring that leads him into "NOT PERFECT", and just like in the game, Outcome Memories, he's ready to attack and kill each survivors before they escape once again...
