Hyperdimension Neptunia belongs to Compile Heart, Idea Factory, Sega and whomever else worked on it.
Want to know how Neptune first met Blanc, Noire and Vert in the past?
Wonder no more!
Blanc grumbled as she finished her paperwork for the day. 'Been only two months since I became Lowee's CPU.' She didn't even get to know her predecessor, though there were some notes and books to read. Thankfully Blanc liked to read, it was fairly relaxing. She kind of wished that she had something to distract from the paperwork other than reading. The notes her predecessor left behind didn't paint the other nations in a very good light and frankly made Blanc not want to deal with the other CPUs at all.
"Ah! Lady Blanc!" One of the Basilicom members spoke up, causing Blanc to look at her. "There's someone who wishes to meet with you."
"Hmm?" Blanc stood up out of her tall chair and walked to the staff member. "Who is it?"
"Hiya!" A girl about Blanc's height wearing a white hoodie with purple trim, stockings that went from her feet up to her thighs, her small feet were covered by white and purple tennis shoes, her hair was short, spiky with long side burns that was light purple in color with eyes that matched her hair in color. "Oh wow!" She smiled brightly. "You're Lowee's CPU?!" The girl ran up to Blanc, a happy, giddy look on her face.
"Yes, my name is Blanc." Blanc nodded at her. "And you are?" She felt the urge to smile, this girl just seemed to incredibly positive and full of energy it was hard to be upset when she was around.
The girl smiled and grabbed Blanc's hands, shaking her hands. "Hiya! I'm Neptune, CPU of Planeptune, want to be friends?"
Blanc frowned and jerked her hands away from Neptune. "I see, so that means we're enemies."
"Awww!" Neptune pouted at Blanc. "But that's not fun! I don't want to be enemies, let's be friends!"
Blanc frowned at her. "No. Because for all I know, you're going to use your friendship with me to steal my shares or cause me harm." She was privately surprised that Neptune hadn't tried to kill her or anything yet.
"Boo!" Neptune pouted at Blanc. "I can't change your mind?" Blanc shook her head and Neptune sighed. "Okay, I guess... You know that Leanbox and Lastation will have new CPUs soon, right?"
Blanc nodded, though she didn't know that those two nations would have new CPUs soon and wasn't sure how this one knew that. "Are you planning on teaming up with them against me?" If this CPU was planning on teaming up with new CPUs to take her on, she'd have to kill this CPU right here and now.
"Nep what?" Neptune had a shocked look on her face. "No way! Why would I try to hurt someone who gave me this awesome hat!"
"...Awesome... hat?" Blanc stared, her pupils shrinking as she saw her hat on Neptune's head. 'She didn't...' Slowly, ever so slowly, Blanc moved her right hand up to her head and lowered it down. 'She did.' She thought to herself as her hand felt her hair and not her hat. "...Give me back my hat."
"Mwahahahaha!" Neptune had an amused look on her face as she turned and ran off. "The hat is now mine!"
There was a flash of light and Blanc transformed into her CPU form. "GET BACK HERE!" Her brown hair turned blue and grew long sideburns as her outfit turned white with blue trim and a large ax formed in her hands. Her face was shrouded in shadow and her eyes were glowing red due to her anger.
The Basilicom member quickly dove out of the way as White Heart rushed through the door, destroying it in the process.
"Nep woah!" Neptune jumped over a slash at her legs. "Oh cool! So that's your HDD!" Her eyes sparkled as she looked at White Heart. "Kind of, woah!" She ducked under a slash at her head. "Come on! Can't you take a joke?"
"Give me back my hat you damn little brat!" White Heart growled.
Neptune pouted as she dodged out of the way of another ax strike, which hit a small statue that was sent flying through a window and into an air balloon, causing it to deflate and crying children to be heard.
Looking through the destroyed window, both Neptune and White Heart gawked at the deflating balloon, their eyes white with black circles around them. "Wow! Good thing it wasn't in the air already." Neptune said, getting a nod from White Heart. "Just look at what you did! You made them cry!"
"ME?!" White Heart rounded on Neptune, who was running off, laughing. "You stole my hat!"
"And it's a great hat!" Neptune shot back as she ran down the hallway, followed by White Heart.
"GET BACK HERE, YOU LITTLE SHIT!"
Neptune threw the hat up and ducked under a wild swing from White Heart. Grabbing the hat out of mid air, she gave White Heart an amused look. "I don't want to hear "little" from a shrimp like you."
White Heart twitched, it was annoying that despite being a deity, she had to look up at everyone just to talk to them. "Shrimp?!" She looked Neptune up and down. "You're no bigger than I am!"
Neptune had an amused look on her face. "Well..." She was surrounded in light and White Heart stared in shock as Neptune grew in height, her hair got longer and was braided into two twin ponytails and she was covered in a black and purple processor unit. "I'd say I am." Her voice, which was childish and ditzy before, was now deeper and almost seductive.
"Wha, wha, what?!" White Heart gawked as she looked the transformed Neptune over.
"You can call me Purple Heart when I'm in this form." Purple Heart smiled at her.
"Boobs... Butt... Hips... WHAT?!" White Heart couldn't believe it! How could someone who was so small turn into such a freaking bombshell?!
Purple Heart smirked at her as an idea came to her mind. "I'd say that you can't really call me little anymore. After all..." She put her hands under her breasts and hefted them up before letting them go, watching in amusement as White Heart's eyes followed them bouncing. She then re-grabbed them and slid her hands down her sides. "I think I'm bigger than you in every place that matters."
White Heart didn't know why, but when she heard that, her anger snapped. "GRAAAAH!"
Purple Heart chuckled as she pulled out a large katana and started to parry, block and redirect White Heart's attacks. "Please, do entertain me."

Several minutes later...
The hallway, several offices, the entrance and her own bedroom were all destroyed, though White Heart wasn't sure how they got into her room over the course of their impromptu fight.
What made it worse was that Purple Heart was sitting on her stomach and looking pleased with herself. Both of them were disarmed, though White Heart found her arms somehow tied above her head and to the remains of her bed. The two were panting and White Heart felt her face flushing as she saw Purple Heart's breasts heaving in front of her. "So now what will you do?" White Heart hated to think about it, but she was completely at the mercy of Planeptune's CPU. She fought the urge to start crying, she was only a couple of months old! 'Am I going to die here?' It wasn't fair! She just wanted to be the best CPU for Lowee that she could be. Why did someone have to come to end her so fast. 'How can an end-game boss show up so damn early? Shouldn't I get to beat up an underling or something first?'
"You know, I meant what I said," Purple Heart, with her deep, almost seductive voice, said softly. "I really wanted to be friends. But since you don't want to..."
White Heart watched in fear as Purple Heart extended a finger and reached in to her face. 'Is she going to gouge out my eyes? Does she have some sort of death beam that can only be done at close range? Is she going to put some sort of obscene marking on my face?'
Purple Heart hovered her extended index finger above White Heart's face for a few moments before grinning and tapping White Heart on the nose. "Boop! You're it."
White Heart could only stare in pure disbelief. "...What? It?" She was so stupefied that she couldn't figure out what Purple Heart meant by that.
Purple Heart nodded and put the pilfered hat on her head. "By the way, Blanc, thanks for the hat." White Heart watched, still stunned as Purple Heart got off and went to the window, winking at her. "That was fun, let's play again. Though, you still need to tag me back." She laughed and flew out the window. The last thing that White Heart saw of the other CPU was the N on the part of the processor that covered Purple Heart's butt.
"...Wait, she... Tag? Play?" White Heart blinked a few more times as she tried to think of something other than how nice of a butt Purple Heart had. Suddenly, she realized something very important. "SHE STOLE MY HAT!"

Several months later, Lastation...
Noire, newly born CPU of Lastation, yawned as she rubbed the sleep out of her eyes. Her long, black hair, was a total mess and her red eyes showed nothing but exhaustion. "Urgh, I should get more sleep." Three hours was NOT enough sleep. Tiredly stripping out of her pajamas and down to her white panties, she looked around in confusion, her eyes still closed, as she heard a giggling noise somewhere. "What's that?" Rubbing her eyes as she heard the giggling noise some more, she frowned softly. "That sounds like that CPU that visited yesterday. What was her name again? Nepthupyutyuoonu or something?" She was surprised that an enemy CPU would just show up out of the blue and ask to be friends with her, but Noire really didn't have an interest in being friends with her.
Well, that wasn't true, Noire didn't mind the thought of being friends with the other CPU, but she was worried the other CPU was just going to trick her or something. 'Maybe I shouldn't have dismissed her outright?' Her predecessor had left several books and notes about how to be a good CPU and had mentioned that it was a bit of a lonely life as any human friends a CPU could make would grow old and die while the CPU stayed young and healthy and not to trust CPUs of other nations.
Being alone wasn't a thought that scared Noire, but at the same time she didn't enjoy the thought.
"BAH!" Noire grumbled and went to her closet and opened it up to put on a dress and face the day.
*SPLUT*
Noire blinked, several times, as her face, hair, shoulders and breasts were covered in what seemed to be something cold and sticky. Sticking her tongue out, she was able to confirm that it was banana in flavor. Putting her hand on her face, she wiped the stuff off of her face and saw that she had been hit in the face with a pie, as there was a pie pan on the floor in front of her. "What's this?" Noire knelt down as she saw a card taped to the bottom of the pie pan. "I got you, ha ha ha ha ha. What the heck?"
"Mwahahahahahahaha!" A voice full of jubilation and humor exclaimed from behind Noire, causing her to screech as she jumped in the air so hard that she hit the ceiling of her room. "I got you!"
Noire landed on the ground and saw, through the goop that was dripping down her face, the CPU that had introduced herself yesterday running to the window. There was a flash of light and Noire stared as the young looking CPU turned into a much older, curvier and sexier person. "...What?" She idly rubbed the bump on her head from where she jumped to the ceiling and hit her head.
"In case you forgot, Noire of Lastation." The CPU looked at her with a smug grin on her face. "My name is Neptune, though in this form, my name is Purple Heart." She put two fingers by her forehead and gave Noire a small salute. "Do try to not be boring, after all," she held up a white cloth and Noire felt her face turn bright red as she glanced down and confirmed that, yes, Purple Heart had stolen the panties she had been wearing, "you might want these back. Who knows what kind of vile, dirty, and perverted things I will do with them? You might have better luck getting these back than the CPU of Lowee has had with getting her hat back."
"YOU DIRTY PERVERT!" Noire yelled as Purple Heart flew away. There was a flash of light and Noire's hair had turned white, her eyes green and she was clothed in a black body suit. "I, CPU Black Heart, will not stand for this!" She yelled and flew off after the laughing Purple Heart.
It didn't take her long to catch up to Purple Heart, who was near the mountains that split their two nations apart. "You know, I was thinking, maybe I'll see if someone wants to buy your underwear?"
Black Heart's face turned bright red. "You wouldn't dare!"
"You're right, that wouldn't be right." Purple Heart nodded and Black Heart sighed in relief, hoping that this was just some sort of twisted way to catch her attention. "Okay, that's fine, I'll figure something else to do with them. Maybe I can post something online and ask what to do with them?"
Black Heart twitched. "You wouldn't dare. Give me my underwear back!"
Purple Heart merely smirked at her. "No. You'll have to take them back. Word of warning though, if you fail to take them back, I'm stealing your processor this time, you can fly home naked."
Black Heart twitched and growled. "GIVE ME MY PANTIES BACK!" A large sword appeared in her hands and she rushed at Purple Heart, who chuckled while grinning and putting the panties away and pulling out a large katana.
The two fought across the mountain range for several minutes, their blades clashing, along with special techniques before Black Heart found herself sitting on the ground, her sword stuck in a tree not too far away and her outfit was in tatters. There were strips of cloth over her nipples and crotch, protecting a very small amount of her dignity.
Purple Heart's outfit was also in tatters, but she was standing and pointing her katana at Black Heart. "Well, I win, but now your processor's torn up. Hmm... That's no fun. Oh! I know!" She pulled out a camera and Black Heart stared in shock as Purple Heart smiled at her, it wasn't a nice smile. What made it worse was that Purple Heart used her katana to move the strips of cloth out of the way, fully exposing Black Heart as she took pictures. "There, this will be perfect."
"I thought you wanted to be friends!" Black Heart's face was red and tears welled up in her eyes. "Friends wouldn't share those to everyone!"
"Hmm... You're right." Purple Heart said and Black Heart sighed in relief. "I'll tell you what, you go home, train and get better and challenge me to a rematch..." A slow grin came to her face as she chuckled. "As for me, I'll keep these for myself. Who knows what kind of evil, lewd and perverted things I will do?"
Black Heart twitched and growled as Purple Heart flew off. "I swear... I'll get my revenge on you!"

Almost a year later, Leanbox...
Green Heart, newly minted CPU of Leanbox, sighed as she flew home. "Can't believe there were so many monsters out there today." They weren't too bad and they had to be put down, but there had been so many of them. Yawning, she looked forward to either sitting in front of her computer and logging some MMO hours in or playing on her console or just taking a nap, whichever felt most appealing to her at that moment.
As she got closer to her Basilicom, she realized something was dreadfully wrong. After all, her Basilicom was green and white, not purple, nor fluttering in the wind. "What the heck?" She got close and touched the stuff. "...Toilet paper? ...Someone covered my Basilicom in purple toilet paper? ...Someone actually took the time to do that?" Green Heart wasn't sure whether or not to be impressed or angry.
"Lady Green Heart!" One of her Basilicom staff members waved her down and held up a disk. "Look! A message for you."
Green Heart flew down and took the disk before pulling out a portable disk player out of her inventory and pushed play. She raised an eyebrow as she saw a CPU with dark purple hair done up in braids looking at the camera. "I called you the other day, Vert of Leanbox, to ask if you wanted to be friends, you declined my offer. I understand, after all, we're enemies. By the way, nice Basilicom." Suddenly the CPU grinned and turned the camera to reveal hundreds of rolls of purple toilet paper. "I wonder if you have enough for all your bathrooms. Don't worry, I'll give them to you for free."
Green Heart twitched and she decided that, yes, she was angry. "That's it! This means war!"
"...You're going to fight because of this?" The Basilicom member asked, shocked.
Green Heart looked at her in confusion. "Who said anything about fighting? I'm going to prank her smarty-pants butt off! The prank wars have begun!"
The staff member sweat-dropped heavily.

A few weeks later...
Purple Heart was sweating as she looked at Black Heart, White Heart, and Green Heart, seeing how she was tied up and unable to move. She could transform back to normal, but she would be helpless if they decided they wanted to cause her severe pain. "...So..."
"You stole my hat!" White Heart growled, she STILL hadn't gotten her hat back yet!
"And my panties!" Black Heart was red in the face. She could only imagine what Purple Heart had been doing with her underwear.
"And you covered my Basilicom in toilet paper!" Green Heart glared at Purple Heart.
Purple Heart sweat-dropped slightly. "...You're not mad about the BL manga I slipped into your bedroom?"
Green Heart suddenly perked up in delight. "That was you? I must thank you, I've been awakened to a whole new world of enjoyment. Tell me, do you enjoy it?"
"Not really." Purple Heart muttered softly, she preferred straight and lesbian porn personally. She gulped as Green Heart's visage got dark again. "Um..."
"Ladies, even though we're enemies, I think we can agree to a truce just this once." Green Heart said, getting nods from Black and White Heart.
Purple Heart gulped again as the three CPUs somehow loomed large over her. "...Mercy?"
"No." The three said at the same time.
"YEEP!"
(-)
Several minutes later, Purple Heart found her face covered in whipped cream thanks to Black Heart, the top of her breasts doodled on thanks to White Heart and, worst of all, an Eggplant stuffed in her mouth thanks to Green Heart. 'I can't believe something so vile and disgusting exists!' She legitimately thought she was going to die the longer she had the thing in her mouth.
"You know..." White Heart tapped her chin. "While that felt nice, I still don't have my hat."
"And teaming up to humiliate her..." Black Heart was grimacing. "I don't feel like I accomplished anything."
"Hmph!" Green Heart smirked as she crossed her arms under her breasts, enjoying how they bounced as she did so. "Well, obviously, I was most effective."
"What did you say?!" Both White and Black Heart yelled at the same time as Green Heart chuckled.
"You heard me." She smirked at them. "Unless you two think you can out-prank each other, myself and Purple Heart, just admit I was the best."
"Dream on!" Black Heart yelled in anger.
"Yeah! I'll show you!" White Heart snarled. "I'll leave you so humiliated you'll never show your fat ass ever again!"
"Fat ass?" Green Heart twitched in annoyance. Her butt was not fat! Her hips were wide and her boobs were big, so her butt being big was a natural result! "So then we agree? Prank War?"
"YES!" The other two yelled and flew off to their Basilicoms. Green Heart chuckled and flew towards hers.
After they were gone, Purple Heart glowed and turned back into Neptune. After squirming and struggling to get out of the trap she was in, as it was designed to hold her HDD form, not her human form, she got to her feet and ripped the eggplant out of her mouth. "BLEEEEEAAAAAAAAAHHH! OH MY TRUE GODDESS THAT IS DISGUSTING!" Neptune yelled while trying to claw at her tongue. "Imma make growing eggplants in Planeptune illegal!"
After calming down from the near poisoning via eggplant, Neptune smiled brightly. "They're better than the CPUs that ran their nations before them." That gave her hope that she could be friends with them and a part of her mind noted that she had at least partially got what she had wanted. At least they weren't fighting violently or trying to kill each other in their sleep.
"I just hope it lasts." Neptune muttered and hoped that she could become friends with them in the future.
And that's how Neptune, Noire, Vert and Blanc all met in this world.
Remember, both Vert and Blanc have commented that the war wasn't always about fighting violently, that at one point they were trying to humiliate each other and not kill each other.
And yes, Purple Heart was a LOT more playful in this world than she is in canon. Or, at least, more openly playful in this world.
Anyway, that's it for this flashback.
Hmm... Oh! I know! Time for a Nepstation!
"Welcome to Nepstation, I'm C-Sha and with me is..."
"Blanc."
"So that was an interesting flashback, huh? She stole your hat?"
"...I LIKED that hat. It was my first one."
"Did you ever get it back, Blanny?"
"No. Oh well, at least my panties never got stolen."
"I HEARD THAT!"
"Oh, it's Norry."
"Don't call me that, C-Sha!"
"I suppose getting your panties stolen is less embarrassing than what Neptune did to you while you were asleep."
"Oh? What happened to Norry in her sleep?"
"Well, she..."
"Don't tell her, afro-head."
"...You just HAD to remind me of that, didn't you?"
"What's this about Blanny being an afro-head?"
"...Nothing, fine, Noire, I won't comment about what happened in your sleep."
"What? What? Someone tell me!"
"Anyway, Blanc, let's hurry up before, uh..."
"MMMPH!"
"Fine, if Blanny won't tell me, I'll smother her in my boobs!"
"...She really isn't fighting too hard to get free, is she?"
"Nope. Anyway, we're almost out of time. Want to give a preview?"
"Sure. Jupiter and the others are finishing up their time in Leanbox, soon it's time to return home, but what will they find when they get home? Wait, what? Is someone dying or something?"
"Or something. Anyway, this is C-Sha..."
"...And Noire..."
"...Mmm..."
"I think Blanny's liking this too much."
"Or she passed out. Anyway, that's it for us, we're signing off."
