Hyperdimension Neptunia belongs to Compile Heart, Idea Factory, Sega and whomever else worked on it.

So, if you remember my short "Infinite Crisis of Infinite Neps" and how there was a serious Neptune that didn't have a sister but Vert did, well, Sitting on the Event Horizon liked the idea so much that he wrote a story about what happened after that Neptune returned to her Gamindustri. If you want to read it, it's called "Hyperdimension Neptunia: Cure for A Lonely Heart". It's in my faves if you want to quickly get to it.

In the Hyper Dimension...

Sighing as she slumped to her knees against the floor, Noire, twin-tailed black-haired CPU of Lastation, hung her head as despair started to settle in. Her hands were chained above her head and due to the lack of shares among other things, she couldn't break them. "I hope Uni got away safely." Noire muttered softly. What made the capture even worse to her was the fact that her clothes had been torn off of her after she had been brought to the holding cells, leaving her in just her panties before her captors had shown some decency and had taken one of her bikini tops and put it over her breasts. She tried to adjust her legs as they were falling asleep but found that to be impossible as her bare ankles were shackled to the floor.

In the cell next to hers, Blanc, the short, brown-haired CPU of Lowee snorted, she was in her undershirt and panties, her hat was missing and she was shackled to the wall with her arms and legs bound in an "X" pattern. "I'm sure that Rom and Ram are fine. But where are we?"

On the other side of Noire in her own cell, Vert, a very busty blonde woman, spoke up. "I would tell you if I could see outside, but I find it hard to look anywhere right now."

Noire looked over at Vert and grimaced as she saw the blonde upside down and naked with her arms chained behind her back with her hair brushing across the floor. "Are you okay, Vert?"

"I'm pretty sure that I'm fine, but I feel very weird with all the blood flowing to my head like this." Vert answered her. "Also, this is doing wonders to relieve the stress in my shoulders and back, though having my breasts rubbing up against my head is kind of weird."

"They should have put weights on those cow tits of yours just to stretch them out." Blanc grumbled in annoyance as she tried to get comfortable and failed. "...We're going to die tomorrow, huh?"

"Yeah..." Noire sighed softly. "I don't know what's worse, being drained to a slow death while being somewhat conscious that it's happening over the course of years or facing a quick death the next day."

"If I had known that I would be dying like this," Vert spoke up, "I would have done more to make Nepgear my little sister."

"Tch," Blanc scoffed, "even now you're going on about that? Newsflash, Thunder Tits, Nepgear would never leave Neptune for you, no matter how much you flaunt your boobs at her."

Vert chuckled softly, "I know, Nepgear loves Neptune too much to leave her, even when Neptune takes advantage of her. But you're misunderstanding me, Blanc." The naked and bound blonde smirked as she continued. "When I said I should have done more to make Nepgear my little sister, I mean I should have tried to marry Neptune."

"HUH?!" Both Blanc and Noire couldn't help but yell in shock.

"Since when are you interested in Neptune?!" Noire asked as she twitched at the thought of Vert in a tuxedo and Neptune in a cute little bridal dress.

"Well, I do like how utterly adorable Neptune can be," Vert answered her, "plus with how you and Blanc always seem to have the highest amount of shares, if our two nations became one, both of us could compete with you on a more even footing."

"Or fall to ruin more quickly." Blanc muttered, though she admitted that Vert had some solid logic with what she was saying. "Besides, you wouldn't marry Neptune."

"Oh?" Vert's voice was curious. "I'd love to turn my body to look at you, Blanc, but even if I used my breasts to act as a counter-weight to spin me, I'm not dangling by a chain, from what I can tell, my legs are bound by some sort of metal mittens connected to a solid metal bar." Vert lifted her head and looked down her body. "Yes, a solid metal bar."

"Was there a point to that?" Blanc grumbled in annoyance.

"Ah yes, I got distracted," Vert sounded a little embarrassed about that before she continued, "but what makes you think I wouldn't marry Neptune?"

"You barely interact with her." Blanc answered. "Besides, Planeptune and Lowee have a much longer history than Planeptune with either Leanbox or Lastation."

"So you're saying you would marry Neptune then?" Vert asked as she tried to twist her body to look, only to stop when her breasts swayed, bobbed and slapped her in the face.

Blanc was silent as she thought about it.

"It wouldn't work for her either." Noire suddenly spoke up. "I'm closer to Neptune than either of you."

"Only physically," Blanc answered Noire. "As for me? Well, when Neptune's not being loud and annoying, she's kind of cute, she's good with Rom and Ram and she's really good looking when she's Purple Heart."

"What about you, Noire?" Vert asked the remaining CPU. "Would you like to marry Neptune?"

"Even if I would," Noire answered, her face turning red as she thought about it, "I'm not sure how it would work out."

"Well, if we're being honest," Vert replied to her, "no one knows how marriage would work out."

"Would being married to Neptune be any different than what we have now?" Blanc asked softly. "We basically live in Planeptune when Neptune's around and we have nothing to do."

"Except that there'd be the chance to do lewd things." Vert answered and even though no one could see it, she had a lewd grin on her face.

"That won't happen." Noire scoffed. "When it comes to romance, Neptune's more shy than I am." She ignored the laughs from the other two. "I was sitting down and watching some mecha anime show that I was told was interesting and Neptune came over to watch with me. There was a scene where the main character kissed his then girlfriend and Neptune started blushing and stammering super loudly and I had to turn on subtitles just to follow along. Don't even get me started on the implied lovemaking scene."

"...How bad was it?" Vert asked, curious.

"I think both of our faces were so red that you could have used us as traffic lights." Noire muttered, remembering that. "Neptune actually passed out when the scene was over, muttering about it being too lewd."

Both Vert and Blanc laughed at that, though there were slaps of flesh as Vert's laughing caused her large breasts to wiggle and jiggle and bounce against her body.

"You know," Noire spoke up after a few minutes, "I know she's only been gone two weeks, but I really do miss that goofball."

"Just in case none of us make it." Vert spoke up, "any confessions you want to get off of your chest?"

"Why don't you start?" Blanc answered, "with the size of your boobs you probably have more than a few things hidden in them."

"I'm afraid not," Vert sighed softly, "my captors were... VERY thorough with checking to make sure that I had nothing hidden between, under or even in my boobs."

"...You can hide stuff IN your boobs?" Noire and Blanc both asked at the same time.

"Only if I wanted to make my nipples horribly disfigured." Vert answered honestly. "As for my confessions, well... I do enjoy me some studly and cute boys."

"Really?" Noire looked at Vert, a shocked expression on her face. "Is that why you like BL so much?"

"Yes." Vert chuckled softly. "I do sometimes wonder what it would be like to have a male romantic partner. Don't get me wrong, I do love cute little girls more, but I sometimes fantasize about it."

"...Fine," Blanc spoke up, "I like women with big boobs and nice round butts."

"Oh?" Vert answered, shock in her voice. "I'm surprised, with how often you call me Thunder Tits and talk about how you hate my boobs."

Blanc growled at her. "Because you keep taunting me with your damn tits! I don't mind the fact that you have them! You just keep going 'oh look at me, aren't I special with my big titties, tee hee' and 'poor Blanc, to be so deprived of something so wonderful' over and over again!" Blanc had tears falling down her face as she looked down. "I hate it... I hate being this tiny, flat-chested, worthless CPU that only pedophiles could enjoy."

"...Blanc," Vert spoke up, "I know it's late, but I'm really sorry. I had no clue that my teasing bothered you so much."

Blanc didn't say anything as she looked down at the ground. "...It really hurts when you tease me over it. Some days I wish I could grow boobs bigger than yours and have hips and a butt that would make you green with envy just to show you what it feels like to not be the biggest around."

Noire sighed softly. "I...I cosplay..."

"We know." Vert and Blanc said at the same time.

Noire blushed and shook her head, not that either of them really saw it. "No! I know you know about my normal cosplay... But... Um..." Her face turned bright red. "I sometimes do cosplay as hentai characters from anime."

"...You watch porn?!" Blanc yelped in shock. "I know Vert's a giant pervert that openly looks at BL manga and games, but you?!"

"Yes! I look at porn, okay?!" Noire snapped her head up. "I read it, watch it and there's hardly a genre I don't watch."

"Oh my!" Vert chuckled softly. "If we get out of here I'll have to invite you over to watch BL stuff with me."

Noire sighed and looked up. "...I wonder how Neptune's doing. I wonder if Nepgear got her back yet."

"Knowing Nepgear," Blanc spoke up, "she found a way. Our sisters tend to be pretty good at finding ways to help us when we need help."

"Yes, but will Neptune be back to normal?" Vert asked, "or will she be the way she was before?"

Both Noire and Blanc were silent as they thought about it. As much as Neptune annoyed them...

They'd rather have her back than the cold-hearted and ruthless Purple Heart that had almost killed them on multiple occasions.

In the Ultra Dimension...

A girl looked around in confusion. "Where am I?" She asked as she looked around. She was on a stone path but all around her were swirling clouds on the sides, above and even below her. "Woah, I'm in the middle of the sky! This is so neat." She looked at everything a bit more and discovered, to her shock, that it looked like there were floating pieces of glass floating in the air between the clouds and where she was. "What's going on?" She asked.

After getting no reply, she sighed and walked forward, following the path. As she walked by, the glass started to get covered in static before showing her images. "What the?"

"So..." There was a woman with long purple hair done in twin braided ponytails and a black body suit facing off against a woman with short blue hair, but with long locks, a white body suit and holding an over-sized ax, a woman with large breasts and a white body suit but this one had long green hair in a ponytail and she held a spear and finally a woman in a black body suit but with long white hair and she was holding an over-sized sword. "You're the new CPUs for me to kill, huh?"

"What are you talking about?" The blue haired one asked, confusion in her voice and on her face. "We were just born."

The purple haired woman sneered at her. "So what?"

The girl watched in horror as the purple haired woman utterly trounced the other three, leaving them on the ground with broken bones and blood coming out of their body from various angles. "What the hell!? She's a monster!" She gasped and held her hands over her mouth as the purple haired woman stabbed the white haired woman in the shoulder and twisted her sword before slashing out, cutting the shoulder and leaving a spray of blood everywhere. She then walked over to the one with large breasts and started to stomp on them, causing the green haired woman to cry out in pain. "STOP IT! STOP!" She fell to her knees, tears falling out of her eyes as she watched the purple haired woman walk over to the last one and kick her in the stomach and ribs several times over and over while she coughed up blood and cried out in pain. "NO MORE PLEASE!"

"Pathetic," the purple haired woman sneered at the three beaten and broken other girls as she turned away, "if I ever see you three again, I won't hold back like I did today." She flew off, leaving three badly injured women behind her.

As the image disappeared, the girl sobbed softly. "What was that? What was that?!"

"That was you." A voice that sounded like the woman in the image spoke up. Jumping up, the girl spun and came face to chest with the woman in the picture. "Hello, Neptune." She gave the confused girl a smirk. "It's been so long since we were able to meet."

Neptune's eyes widened. "Who are..?"

"I suppose you would be confused," the woman chuckled softly, "I'm you. I'm Purple Heart."

Neptune's eyes widened as she took a step back. "No... NO!"

"Search your feelings, you know it to be true." Purple Heart grinned at her.

"NO!" Neptune fell to her knees and put her hands over her ears. "I'M NOT A MONSTER! I DON'T WANT TO BE A MONSTER!"

"Jeez!" A new voice spoke up and Neptune lifted her head, tears falling from her eyes as she saw... Herself dressed in a purple dress and small hooded coat, looking at her in annoyance.

"First of all, Purple Heart, don't traumatize her." The other Neptune shook her head. "As for you, Neptune, realize that we're just part of you."

"...Huh?" Neptune looked at her other self in confusion. "What do you mean?"

"What the meanies mean," another voice spoke up and Neptune looked up to see... Another Purple Heart, who was carrying another Neptune, who was wearing a white hooded parka, "is that we're all you." The parka wearing Neptune said as she was put down. "Basically, it's like this... This Neptune and Purple Heart are you from when you were born until you lost your memories awhile ago, and like, I and this Purple Heart, are you after you lost your memories."

Neptune just looked at them in confusion and fear.

The first Purple Heart sighed and shook her head and Neptune noticed that her eyes were purple while the second Purple Heart had blue eyes. "Listen, right now, your mind is in a state of flux due to some idiot finding a way to undo the block on your mind. So right now..."

"You don't have any identity," the blue eyed Purple Heart answered, "what you see is all your years of memories, both before and after your amnesia, floating around at once."

"But because of that moron's brainwashing of you and the device he put on the back of our head," the dress Neptune spoke up, "it's all floating around without any sort of control."

"Like a big storm!" The hooded Neptune continued, "if you woke up now, you'd be unable to cope and would be in a corner rocking. And what kind of main character would be like that?"

"Anyone who's gone through hell?" The purple-eyed Purple Heart asked sarcastically. "Listen," she pointed at Neptune, who gulped softly, "the truth is, you have to choose who you really are, Neptune. Half your life was cold and heartless, that's us and half your life was playing the role of the ditzy idiot."

"...So who am I?" Neptune asked softly.

"That's what you have to discover." The blue-eyed Purple Heart said as the four disappeared. "You need to observe your memories of the past and absorb the feelings of each memory to determine who you really are."

The next thing Neptune knew was that the window that showed her the horrible memory had turned into data and then rushed into her, causing her to cry out and fall to her knees as she felt emptiness, anger and pain flooding her. "So this... Was what I was like back then?" She shuddered and felt like puking. "Wait, what would happen if I puked in my own mind?"

Neptune didn't know, but she did know one thing.

She wanted to know who she really was.

To be continued...

So I probably should move this to a stand-alone story, but I worry about some stuff. I'm waiting for the staff to get back to me about some stuff before I make any final decisions.

If any of you noticed, the Purple Heart that was brainwashed had purple eyes, so I used those eyes to indicate pre and post amnesia Purple Heart.
