Hey everyone. Been a while since I did something here. I kinda lost interest in writing this for a while, but now I feel I should pick up where I left off. Besides, I kinda want to give this story a proper end one of these days.

For those still following, I looked back in the previous chapters, and decided to ouch up on them, for making additional dialogue to editing some paragraphs and correcting some grammatical errors. So if you want, feel free to check them out. For now, let's get this new chapter started.

WARNING: This story contains nudity and sexual content inside. If you are not into this, turn back now.

With that said, enjoy.

It was night time in Lastation when Noire arrived back at the Basilicom. She breathed a sigh of relief, knowing that she was back home after a long day of work. Most of it involved doing quests, while others involved odd jobs. She had also been searching around for any signs of Blanc, Vert, or Nepgear. Despite all of her efforts, however, there was no indication of them anywhere. It was as if they vanished from the face of Gameindustri. It was like they never existed in the first place. Noire wondered how the nations would cope without their CPUs.

"This is starting to get disturbing. Just where could they be?", the Lastation CPU wondered aloud.

Even if she could not find them, there was no point in dwelling on things that she cannot do. Noire sighed as she went inside her Basilicom. She wanted to take a break from her usual routine for the rest of the week and take her mind off of the recent happenings. As she walked through the Basilicom, though, she couldn't help but feel that something felt off, as if nothing felt the same as it was before. The CPU brushed it off, thinking that it may just be her thinking about the disappearances again.

Noire continued on her way to her room and was about to pass the door to Uni's room when she noticed something. On her sister's door, there was a note attached to it. Curious, she pulled the note off and looked at what it said.

"Went out for the day."

"Will be back later."

"Left you a gift in your room."

Your Sister, Uni

"She left a gift for me? Aw, that's sweet! I should thank her when she gets back", said Noire, smiling at the thought.

As walked away from her sister's door, she had no idea what had transpired in the Basilicom while she was away. Inside Uni's room, the Candidate's clothes lay scattered within the room, and a silencer for a handgun laid on the floor, covered in some fluidic substance. Of course, the CPU wouldn't find out about this. By the time she would, however, it would be too late.

Entering her own room, Noire sighed and stretched her limbs, groaning a bit, and looked around for her "gift". She looked towards her bed and saw a a small box. Picking it up, she opened it up and looked inside, surprised by what she saw. Inside the little box was what appeared to be a black collar. Although she was happy that her sister gave her a gift, she was a bit confused by it.

"Kind of a strange gift, that's for sure. But it's the thought that counts, I suppose", the CPU said.

Taking the collar out to examine it, she also noticed another note. She took it out and read it.

"Wear it around your neck."

"I'm sure you will love it."

"Have a great time, sis!"

"Well, if Uni wants me to wear something like this, then who am I to judge?", said Noire.

And she had an idea that she believed would coincide with the black collar. Opening up her closet, she turned on the light inside, revealing all sorts of dresses. The thing about these dresses, though, was that they weren't any ordinary outfits. They were all part of Noire's secret cosplay hobby. And since she had the whole Basilicom to herself, she was not worried about partaking in a little fun with her costumes. The Lastation CPU smiled as she started to take off her dress, hair ribbons, and any other pieces of clothing she had on her, scattering them on to her bed until she was in her bra and panties.

"Now... where shall I start?", Noire pondered aloud, thinking about which cosplay dress she would wear and which one would match perfectly with her new collar.

"Welcome home, master!~ Hehehe!~", Noire giggled.

Posing in front of a large body mirror, the CPU was in her main office, making various poses and acts. She was wearing what appeared to be a maid uniform, complete with hair band and the black collar around her neck. Surprisingly, the collar was a perfect fit, wrapped around her throat very nicely. She smiled as she continued to pose in her costume.

"Hehehe!~ I wonder what else this could match with?", Noire asked herself.

She then started taking off her maid costume so that she could try something else. She had many other cosplay outfits laying on the desk nearby. The CPU tried many different outfits, from a cat-girl styled dress to even an adventurer's costume. A lot of the costumes blended very well with the black collar, and Noire was having a fun time. At last, the Lastation CPU stopped with a black and blue magical girl dress. She gleamed as she posed again.

"In the name of Lastation, I shall punish you! Hehehe!~", giggled Noire, breaking her composure a bit.

She then spun around to get a full view of herself in her cosplay. The CPU had been grinning and giggling the whole time when she was going through her various dresses. She felt she was having a good time, forgetting about the troubles of the world. She even thought that the black collar looked really nice on her in anything she wore. Noire actually wanted to thank her "sister" when she got back.

"Well, I think that's enough for tonight. I just might show this collar off tomorrow", she said.

She moved her hands to her neck to remove the collar. But as soon as she tugged on it, a sharp pain stung her in the back of her neck. The Lastation CPU recoiled from the sudden pain.

"Ouch! What was that?!", she exclaimed.

Noire felt the back of her neck to feel any signs of a sore spot, but there was no sign of any bump or injury. It was very strange to her. She wasn't sure what had happened. Her thoughts went back to the collar.

"Did the collar sting me?", Noire wondered aloud. "This is weird... I don't know what's... I-I don't... Ugh..."

All of a sudden, the CPU's head was starting to become foggy, and her vision became hazy. She stumbled a bit as she tried to keep her balance, groaning as she held her head with one hand while placing her other hand on the desk next to her other dresses.

"Hard to... think... ugh...", said Noire sluggishly, trying to keep her senses straight.

But it was to no avail. She hand slipped off the desk, knocking over her various outfits on to the floor. The Lastation CPU hit the floor with a thud, her consciousness fading out...

Ten minutes had passed before Noire started to wake up from her unconscious state. She groaned as she started to open her eyes and slowly got back up. She looked around the room and then all over herself, seeing that she was still in her magical girl clothes.

"Ugh... What happened?", said the CPU, clutching her head with her hand.

She wondered what had transpired while she was out cold. Then she remembered about the collar, how it stung her, and how she had suddenly didn't feel good afterwards. Even now, she could still feel some of the effects from her head pounding. Noire sighed as she stood back up.

"Geez, what a pain... Just what was that anyway?", she asked herself.

She then placed a hand on the collar around her neck. The Lastation CPU frowned as she felt its firm grip around her throat. When she first found it, she thought it would be a fashionable accessory for her dresses and cosplays. Now it seemed to her that there might be something wrong with it, almost as if it sent off a bad vibe.

"Just what kind of collar did Uni get me? How am I supposed to... get it off... my...", Noire said before drifting off.

Her thoughts slowly turned away from her collar, her attention now focused upon her outfits, now scattered upon the floor. She would normally clean up a mess like this immediately, especially when it came to her cosplay clothes. Yet, when she looked at her various dresses, something within her just stopped her from moving. The CPU stared at the pile, feeling a wave of discomfort. At last, she subconsciously took a step back from the clothes pile. A burning sensation slowly started to crawl all over her entire body.

"What is this?... My body... It feels like I'm catching on fire... But why?", Noire thought.

She held a hand tight to her chest, the burning feeling becoming more intense with each passing second. She wondered if the collar had something to do with this like her headache. But anymore thoughts of this were soon replaced by the burning sensation becoming more stronger, as if the room itself was also getting hotter. The CPU panted and gasped as she started to sweat.

As if the unexplainable heat wasn't bad enough, her body was also starting to feel itchy, mostly were her body is covered by her clothing. She did not understand why this was happening, but the Lastation CPU felt like she was going to suffocate if she didn't do something quickly. The burning and itchiness grew more and more intense. By that point, she had reached a decision.

"Agh! It's too hot! I-I'm burning up!", Noire exclaimed frantically.

She tugged hard on her cosplay dress, trying desperately to get herself free form the clothing in an effort to stave off the heat. Irrationality had started to cloud her judgement, as the dress was somewhat complicated to put on, let alone remove. Noire, however, felt she needed to be set free immediately. She pulled harder and harder on her dress, even trying to pull it in opposite directions. Bringing out inhuman strength, the CPU eventually manages to tear open her dress, splitting the front in half. She struggles to quickly get it off of her body before tossing it away from her, the ruined outfit landing on the floor. She was now in nothing but her bra and panties.

"Haah... haah... haah...", Noire panted heavily.

She stared down her now torn cosplay dress, a look of confusion and frustration forming on her face. She slowly felt body start to cool down, and her itchiness dissipating. Although she was relieved that the heat and itchiness were going away, the CPU could not believe what she had just done. She had just ripped one of her dresses in an effort to take it off. And yet, as she stared at her fallen article of clothing, she felt nothing.

"I just did that... so why don't I feel bad about it?", she wondered aloud.

Noire glanced towards the full body mirror nearby, looking at her half-naked body. Her beautiful feminine figure really stood out without her dress covering her. And as she looked at the collar around her neck, she couldn't help but think how sexy she looked right now. The Lastation CPU stared for what felt like a minute before shaking her head in realization.

"Gah, there's no time to think like that! I need to find a different dress to wear", she said.

She started to pick up her ruined cosplay outfit, thinking she can repair it later via sowing. Then she started to pick up her other clothes that had fell to the floor. Just as she was about to walk away, however, a sudden burning within her started to swell within her lower region. Noire dropped her clothes and placed her hands on her abdomen in response, groaning as she stood in place.

"Ugh... what's going- Ack?!", the CPU said before being cut off by the ever growing ache within her.

Noire could feel herself burning from within, reaching all the way down to her womanhood. For whatever reason, she could feel herself getting wet. Why this was happening, she did not know. The CPU thought if this was a side effect from the burning and itchiness she felt a couple of minutes ago, but this was quickly dismissed as the sensation became more intense. And the more she also tried to think about the collar, the more wet her womanhood felt.

"Why is this... W-What is happening... I...", Noire thought, her focus becoming a bit cloudy.

As the intense wave grew inside of her, she thought she could hear something whispering into her mind, telling her to do something. Subconsciously, her hand moved towards her panties and slowly slipped inside. An irresistible urge to touch herself was overwhelming the CPU's mind and thoughts. A part of her mind nagged to her that something about this wasn't right at all, but was quickly silenced as her fingers reached her wet pussy. A soft moan slipped through her mouth as soon as she made contact with her womanhood.

"Mmmm~ Haah~", Noire moaned.

Her hand then started to slowly rub her dripping pussy, moaning in response to the action. As she did this, the burning within her was beginning to disappear. And yet the whispering in her mind urged her to keep going, and Noire subconsciously complied. With each stroke of her fingers, her pussy twitched in response, bringing about a sense of bliss and pleasure.

"I don't know why I'm doing this... but...", the Lastation CPU thought, her mind slowly being possessed by a sexual desire.

She started to move her hand faster as she continued to rub her womanhood, moaning more in response. After a few minutes, she stopped moving her fingers, her hand becoming a bit tired. Noire could see that her panties were now soaked, and when she removed her hand out of her underwear, she saw that her fingers were covered in her own love nectar. Staring at her sticky hand, an urge to taste her fingers overpowered her better judgement, despite another voice telling her not to. The CPU licked her fingers, tasting her own juices, and a wave of pleasure coursed through her. It was unlike anything she ever felt. It felt so good to her.

"...I want more...", Noire said, her mind being overtaken by lust.

She reached down to her wet panties and pulled them down to her ankles, exposing her dripping vagina. After removing her panties, she tossed them aside in a random direction, not caring whether it landed or even still needing them. Noire's mind was made up. She wanted more of this wonderful feeling when she touched herself. The CPU wanted it to last as long as possible. She sat on to the desk's chair, placed her fingers inside of her pussy and moved them around within her walls.

"Ahhh~ Ooohhh~ Oh wow~ This feels nice~", she moaned.

As she moved her fingers in and out of her pussy, the rational voice in her mind was becoming more quiet until finally, it became permanently silent, giving in to the unnatural mindless pleasure. Not that Noire herself cared about it now. All she wanted was to feel more pleasure from masturbating herself. The CPU moved her fingers faster, moaning louder in response. Once again Noire wondered if the black collar, which she almost forgot about, was making her feel this way.

"Did Uni know about this when she... she... Did Uni... Who is that again?", the Lastation CPU thought, slowly forgetting about her sister.

Her thoughts soon went back to the pleasure building up inside of her. Although she was masturbating in her office area, for whatever reason, she did not care whether or not someone would walk in and see her. In fact, the very thought of her being caught in her current situation somehow turned her on even more. Her moans became louder, and her hand moved furiously within her folds. After another minute or two, she felt herself starting to reach her climax.

"I-I'm so close~ I'm about to... to... to!~ Ahhh!~ Aaaahhhh!~", Noire moaned mindlessly.

Seconds later, she released her bodily juices, jerking her head backwards as she moaned in pure pleasure. Some of her love nectar squirted on her chair, while the rest of it ended up on either part of the desk or on the floor. Not that it mattered to Noire, though. She was glad that was able to reach her climax as the effects of her orgasm washed all over her senses. Removing her fingers from her pussy, the CPU licked the juices off of her hand once more.

"Mmmm~ So good~", she said lustfully.

Her pussy twitched again, making her moan again as a result. Noire felt like she wanted more than ever. She placed her hands on her hair ribbons that where a part of her ruined magical girl cosplay and pulled them off of her hair, letting her hair fall down, and tossed her ribbons aside in a random direction. Then, reaching behind her back, she started to release the clasp of her bra. Soon she unhooked her remaining article of clothing, allowing it to slide off of her body, exposing her ample breasts. The Lastation CPU was now completely naked. As her nipples turned hard due to being exposed to the cold air, she tossed her bra in the direction of her wet panties. She then proceeded to grope her chest, moaning softly as she moved them around

"This feels so good~ But it feels so unlike a CPU like me... But... what's a CPU?", the black haired girl thought, her mind becoming more foggy.

It was at this point that her mind was becoming lost in lust. Once again, Noire started to finger her pussy, while a the same time groping her breasts with her other hand, even occasionally either squeezing or licking them. She moaned loudly in blissful harmony. She didn't care if anyone heard her at this point. All she cared about now as reaching another orgasm and relieving herself in pleasure. Soon she would get her wish, as her sensitive womanhood twitched ecstatically.

"Ahhh!~ Aaahhh!~ Ooooohhhhh!~", Noire moaned mindlessly as she reached her second climax.

More of her fluids squirted out of her pussy, and her orgasm went on for what seemed like a minute before eventually ceasing. But this still wasn't enough for the Lastation CPU. She wanted to reach yet another climax.

"It's not enough~ But I... I... Who... am I?", Noire thought, the memory of her own name starting to fade away.

Getting up from her chair, she mindlessly walked to one of the corners of her desk, mainly the one where her pile of clothes were sitting under. Positioning her pussy over the corner, the CPU proceeded to grind her womanhood against the corner of her desk, while placing her arms on top to keep her from falling forward. It didn't seem right, but to her, it did fell right, as if this is what she was meant to do all her life.

"Aaaahhhh!~ Yeeesss!~ Just like that!~ Aaahhh!~", Noire moaned loudly.

Doing something like this would've been really out of character for the CPU of Lastation. However, Noire was not herself anymore, as she was lost in a fog of sexual desire and lust, wanting nothing more than to release her love nectar as much as she possibly could. She continued to grind away at the corner, thrusting more vigorously as time went on. Her eyes rolled upwards as she felt the immense pleasure reaching her brain. At the same time, the whisper in her head spoke to her one more time, telling her to "release her essence" so that "she may be free". Unable to resist, she subconsciously complied.

"I want to cum!~ Please, let me release my essence!~ I want to be free!~", the CPU thought without hesitation.

She felt her pussy twitch in response to this thought, as if it were a reward for thinking this. Suddenly, the black collar around her neck started to glow brightly in a black color, eventually spreading out to her entire body. The Lastation CPU didn't take any notice of this, however, as she was more focused on reaching her final orgasm. Noire loved every moment of this intense pleasure, feeling like she wanted it to last forever. After grinding her pussy on the desk corner for what seemed like minutes, she reached her climax. It was the most powerful orgasm she had yet.

"I'M CUMMING!~ AAAAAHHHHH!~", Noire exclaimed.

Her bodily juices squirted from her womanhood like crazy, a lot of it ending up on her pile of clothes below. As this was happening, a black glowing ooze flowed out from her pussy and on to one of her dresses, staining it in a thick black color. Noire panted heavily, getting herself of from the corner of the desk. As she slowly walked forwards, she stumbled onto her knees, eventually falling on the floor completely, her body going limp.

"I came... so much... I'm free... I... I...", Noire murmured before trailing off completely.

Her mind was starting to fade away from existence. The memories of her friends and family, her past life as a CPU, and even her own name, they were all being erased from her head. Soon all of her memories were gone completely. She was no longer the CPU of Lastation. Before she lost consciousness, the former CPU thought she could see someone across the room watching her. A red skinned individual smiling at her lustfully. Soon after, she blacked out. The black glow around the fallen girl's body soon changed to a dark red color. Her transformation was about to begin.

Standing a few feet away, a red skinned girl with large breasts, grey hair, black wings, horns, a thin tail, black eyes with red pupils, and absolutely no clothing whatsoever was watching the fallen girl. She had been watching the former CPU's last masturbation, and was very turned on by it. She thought that if this one was dirty like this, she could just imagine how great she'll be as one of her kind. The grey haired succubus licked her lips in excitement.

"Welcome to the family, sis~ Hehehe~", she said as she watched the transformation unfold.

The former CPU's bare skin was starting to change color. Her skin pigmentation slowly turned to that of a shade of red just that of the succubus watching her. On her head, a pair of horns grew on both side, curving downward before twisting to a forward direction. The girl's already black hair changed to a deeper shade of jet black, as black as that of a center of a black hole. Next, two protrusions started to grow on the girl's back at an alarming rate before finally, they revealed themselves to be black bat-like wings. Then, a long thin tail sprouted from just above the fallen girl's butt, with a heart-like shape forming on the tip. Her ample breasts also grew a few centimeters, almost to the point that they matched the succubus's own. Finally, a black symbol was etched on to the former CPU's abdomen, almost in the shape of a heart. The transformation was complete.

The grey haired succubus smiled at the sight, as the former CPU of Lastation has now been reborn as her new sister-to-be. She walked to her new sister's body and flipped her over on to her back. She stared at her sister's sleeping face, then looked up and down at her sexy naked body, from her large breasts to her dripping wet pussy. Becoming more horny, she lowered herself down to the floor, placing her face in front of the new succubus's womanhood.

"You are such a tease~ But that's why I'll love you for it, 'Black Demon'~ Hmhmhm~", she said.

The succubus place her mouth over the black haired girl's pussy and began using her tongue to lick away at her folds. She moaned softly as she tasted Black Demon's juices and even suckled on her pussy for a bit. Then the grey haired girl moved closer to her "sister's" breasts and started licking and sucking on one at a time. The black haired beauty began to stir, groaning and moaning in response to the grey haired girl's actions. Opening her eyelids, she revealed that her eyes had changed from red to black with red pupils. She stared at the succubus, who was still suckling on her breasts. When she noticed eyes on her, the grey haired girl stopped her breast feeding and smiled at her.

"Hi, sleepy head~ Did I wake you? Sorry about that, but you just looked so irresistible, I just couldn't help myself~ Hehehe!~", she said.

"Oh, don't worry about it... Uh... Who are you again?", Black Demon asked.

"Is your head still sleepy, Black Demon? It's me, Grey Demon, your sister, remember?", her sister replied.

"Oh never mind that now. Did I say you could stop?", Black Demon inquired, referring to what her sister was doing before she woke up.

"Ohhh~ Ehehehe~ Sorry~", said Grey Demon teasingly as she went back to kissing and sucking on Black Demon's breasts.

The black haired succubus moaned in response as her sister feed upon her ample bosoms. She placed a hand on her sister's head and rubbed it, giving her an indication that she was doing well. Soon Grey Demon went lower down her sister's body, licking away at her stomach area,a d then reaching towards Black Demon's pussy, now more wet than ever. As soon as she placed her tongue inside of her pussy, the black haired succubus moaned more loudly.

"Aaahhh!~ Mmmm, good girl!~ Keep going!~ Aaaahhhh!~", Black Demon moaned excitedly.

Grey Demon did exactly that, licking and suckling on her sister's womanhood. They both had lust on their minds, and each second of their interaction with one another sent them further into a state of pure bliss. Minutes went by, and Black Demon moaned louder and louder as Grey Demon moved her tongue through her pussy. She was about to reach her climax.

"I-I'm about to cum!~ Ahhh!~ Please, eat me out!~ Swallow your sister's love nectar!~", Black Demon moaned ecstatically.

After another few strokes of her tongue, the grey haired succubus aimed her mouth and face above her sister's womanhood. Soon Black Demon's pussy was squirting out her bodily juices at Grey Demon, some landing on her face while the rest entering her mouth, which she swallowed some of, humming softly at the sweet taste. She crawled over her sister's face and they both shared a kiss with one another, their tongues tasting the love nectar. After a few more seconds, they broke their kiss, a thin trail of saliva forming a bridge between their lips.

"Haah~ You know, there are more sisters out there we have to find. Wanna go look for them?", Grey Demon asked.

"What's the rush? I wanna have fun with you first~", Black Demon slurred seductively.

"Ehehehe!~ You're so naughty, sis~", said the grey haired succubus giggle.

"You're one to talk~ Now come here~ Mmmmm~", said Black Demon as she pulled her sister in for another kiss.

They both embraced their naked bodies as they mashed their lips into a deep and passionate kiss, their tongues swirling around in each other's mouths. The sounds of their moans would echo throughout the night, as they would make love with each other in their own way. They would play with each other's bodies all night long, immersing themselves in intense pleasure and bliss.

On the same day as her sister Uni, CPU of Lastation, Noire, faded from existence. With no CPUs left in Lastation, the people would begin to panic worry about the state of Gameindustri. It was believed that both CPUs may have been abducted, while others say that they may have been whisked away by some unknown force. Whatever the case, the only left behind by their Goddess were a ruined cosplay dress that looked like it was torn open, a bra and wet panties lying next to a pair of hair ribbons, and a nearby pile of clothes stained in some sort of black substance, the "essence" of their former Goddess, which had hardened after some time.

Although the people of Lastation feared for their Goddess, none could foresee that she was exactly missing. Just changed. A succubus in her own skin had taken the former Noire's place. A new face would soon reveal itself. She would be known as Black Demon, the Console Devil Girl of Lastation...

Sitting out at the balcony on top of Planetune Tower, Histoire looked at the stars and the full moon shining in the night sky. A face of worry had formed on her face. When she found out about Nepgear's disappearance, she immediately asked the other CPUs if they had seen her or any signs of Blanc or Vert. Unfortunately, no one knew their whereabouts. It was as if they had vanished off the face of Gameindustri. She sent anyone who was available to search for them.

This wasn't the first time a CPU had disappeared from Gameindustri without a trace. But this felt different somehow. The Oracle couldn't help but feel that something was very wrong about their disappearances. She could feel something dark growing out there in the world. She just couldn't quite put her finger on it. A dark change was in the works.

Histoire sighed as she turned to go back inside to try and get back to sleep. But as she turned her back, a shadow rushed by behind her, a familiar giggling sound made shortly after. The Oracle quickly turned around to see who it was, only to see a figure flying away from the tower. Under the light of the moon, she could get a glimpse of what the figure looked like before it flew out of sight. The figure had red skin, bat-like wings, a thin tail, and a couple of horns on her head. What really shocked the Oracle, however, was not only the fact that the red bodied figure looked completely naked, but whoever it was had long lilac hair. Histoire could not believe her eyes.

"Was that... Nepgear?", she managed to say as she stared out to the open city in disbelief.

Five down, and more to come. Who will be the next to fall into corruption?

Hope you enjoyed this one, everybody. Don't know who I'll do next, but we'll see soon. Until next time. And don't forget to leave a review.
