An: Okay, so this is my first attempt at writing something for Hyper Dimension Neptunia. So it might not be that good, but I am going to try anyway. This story takes Inspiration from Hyper Dimension Neptunia Rebirth: Rebirth Of A Goddess by Seraphiane Heart. Please give credit to his or her original story. Just to make a note, I will try to make Neptune less Op in mine but no promises. This takes place during the ending of MK2

I will also add that I am using some things from Destiny 2 supers. The ideas themselves do not belong to me, but Bungie and I do not claim to own HyperDimension Neptunia or Destiny 2. Also all music used is not mine and go to their own creatures.

/ Neptune's POV/

In the desolate Gamindustri's Graveyard, a fight between the four CPUs and the one CPU candidate against CFW Magic is near its end. It was a brutal battle. Almost all of the CPUs were on the floor. The only CPUs who were still standing to fight were Neptune, or in this case Purple Heart, and a Pink-haired Candidate.

It was evident from the beginning that Magic was on a whole different level than them. White Heart was almost forced on her knees, leaning on her ax for support. She was doing better than Green Heart, who was left face against the ground after being hit by a burst of Magic's dark powers. Meanwhile, Black Heart was stuck in a deadlock against Magic, unable to continue fighting.

Magic smirks at the sight and states arrogantly, "Not bad, for an insect, but this ends here." With a quick jab on the face, Magic threw Black Heart onto the ground violently.

Purple Heart gazes around at her fallen friends and Nepgear. She knew that this was going to end as a one versus one with no chances of victory. Purple Heart lungs forward and slashes at Magic three times, but it all proved pointless as each of her attacks were evaded by Magic, who answers by hammering Purple Heart with the blunt end of her scythe making her stagger back. Magic took advantage of Purple Hearts status going now to end Nepgear.

Magic raised her scythe to end the CPU Candidate, who stayed in place scared only for Purple heart to place herself between both and receive the strike instead.

The scythe cut and pierced clean through her chest. Neptune remained standing without moving until CFW Magic yanked the scythe out of her chest. Blood dripped and splattered all over the dusty ground... Purple Heart coughed up blood as she was slowly descending with her life fading away, ending up laying on the ground lifeless.

The awake CPUs watched in horror as Purple Heart's body was left on the ground frozen, and without moving, Magic found this some reason amusing starting with chuckles to end, then bursting on laughs. She smirked at the scene and left the battlefield with satisfied of this show… leaving the remaining CPUs on sorrow at the loss of someone their friend… Noire is still unable to move struggled to no avail… tears began to come out of her eyes as a powerful feeling of impotence invaded her.

Purple Sister descended on shock as she landed. She walked bewildered toward her dying sister, dropping on her knees at the scene of a defeat. Her eyes are continually gazing at the horrible hole left on Neptune's chest. With mostly bleary eyes, Purple Sister takes her sister in her arms. She pulls Neptune into one final hug and cried, "No! Neptune! Please, Neptune! Don't leave me, Neptune!"

Vert, Blanc, and Noire all of them who forcefully deactivated the HDD still wounded gathered around Purple Sister. Watching in grief and sorrow as Purple Heart's life slowly faded away. "Please be true to yourself for me… you know who …... you are and please look after Nep….gear….. Please." after that, Purple Heart's eyes closed one last time as her head went limp. Neptune's life was over, and like that, Nepgear broke down into tears, screams, which reached overall Gamindustri.

The wind moved, and Purple Heart's eyes twitched at the feeling of the sun in her face, her eyes open slowly as she quickly realizes she is lying on the ground. Slowly she moves her upper body off the ground and looks down at herself, noticing she was in her HDD form.

She looked around puzzled and sees that she is in a ruined town with stone walls barely standing... Massive holes in the ground, ashes, and remains of incinerated buildings. "W-What the… What happened here?" Purple Heart asked herself in a worried tone.

Out of nowhere, a voice sounded inside her head. 'So... you're finally up?' she was clearly on confusion, she looked around again just to get answered. 'You're not imagining things. I am talking to you in your head. Some reason me, and you joined bodies when we appeared here." the voice says.

Purple Heart's eyes turn up to the sky, almost as if she is trying to make eye-contact with the one in her mind. "Merge bodies? How did this happen?"

"I'm not sure. I was about to ask you the same. The last thing I remember was crossing the road. And then heard a loud screech on my left… I think it was a car. How about you?"

'Well….. I do remember fighting someone called CFW Magic. I don't remember much else. Regardless. We're here now. What's your name?' Purple Heart asked curiously. 'My name is Eris.' The voice introduced. "I'm… not usually disembodied voice.

"I'm Neptune or in my current form Purple Heart." Purple Heart says calmly.

A few minutes passed, and the internal conversation was done... Purple Heart turned her gaze to the ground, unknowing what to do now... She was right now stuck in her goddess form, having no idea where she is right now, and she didn't know if she would ever see Noire, Vert, Blanc, or Nepgear again.

Neptune changed drastically in these last 50 years… At some moment between She and Eris separated bodies at some point... though, Because Eris remained sharing bodies with Neptune for so long, her own body changed from a standard mage to Goddess. Eris now had a HDD form, also being stuck on it like Neptune is.

Neptune looked with detail once again, remembering Eris's appearance. A young girl around her 19, with long platinum blonde hair that extends so far to her thighs, cyan-colored eyes plus her skin has a lighter color than the usual, however, due to her right now being stuck in her HDD her eye color is dark purple and her hair is dark blue

Due to the discomfort of the processor units, Eris is wearing a black t-shirt, a dark blue trench coat over the shirt, light blue jeans as a legwear, along with black sock and finishing off the look she wears black shoes that have blue and purple accents. Now onto Neptune's appearance itself.

Neptune had similar problems with the processor unit, as Eris did. She was wearing right now a dark blue sleeveless shirt with a casual poncho over it, black cargo pants, and lilac shoes with blue and black accents as a legwear. Her hair was no longer held with the usual twin tail braids style. Instead, it was left untamed and also cut to reach her hips, Her bangs didn't have any notorious change, and her hair color remained with the same dark lilac-purple.

Over these 50 years, they struggled to make a portal that both stood in the front right now, one to lead Neptune back to Gamindustri. "So, are you going to come with me to my world, or will you return to your own?" Neptune asked. Eris glances at Neptune. "I'm a goddess now, Neptune I have to go with you. Going back to my world is no longer an option. As you said, we now have responsibilities." Eris replied it was now both of them going back to Gamindustri Neptune closed her eyes for a few seconds. "I guess we have no choice. We should go now then who knows what's happening in Gamindustri," Neptune says in a relaxed tone. Eris nods as both of them jump into the portal that closed down the moment both were now inside.

An: Now, I know I have skipped a lot, but I don't want to show everything this second. We will see flashbacks of her time in Citadel. Now the topic of Eris. They learned she would only be in Neptune's body for 47 years, but because of Eris being in Neptune's body for so long, it turned her into a CPU, now she is a goddess.

It was like any typical day around the Planeptune basilicom. That was until a black and purple portal in reality. That was when Neptune and Eris came out of it and landed gracefully on the ground near the basilicom. No one saw what happened since it was blocked out with Neptune's magic. Neptune turns and gazes at the basilicom. Then she went up to the basilicom and was about to head in, but a guard stops her. "Halt, do not come any closer. What business do you have at lady Nepgear's basilicom!" With rather uncaring eyes, she glances at the guard and knocks him out in one swing. His body hit the ground, and she mutters two words in sadness, "Forgive me," then she went into the basilicom.

When Neptune and Eris got into the basilicom, she was met with Histoire, IF, and Compa. All three nearly faint at seeing Neptune alive and well. "Neptune? How are you alive? I thought you died?" IF asked uneasily. Neptune turns her gaze away from IF, Compa, and Histoire. The only thing Neptune felt was guilt and when the three examined Eris. She was slightly uneasy, too, but she answers for Neptune instead. "I don't know if you would believe us if we told you, but right now we have bigger fish to fry. Where is The other CPU's and the candidates?" Eris asked. Histoire looks like she didn't trust Neptune or Eris but decides to answer anyway. "They went to stop the Deity of Sin, who currently still has all the CFWs. They are currently in the Gamindustri Graveyard," Histoire says in a neutral tone. Neptune was mad now. "You better be lying to me Histoire WHY would they do something so stupid? All four of us and Nepgear lost to CFW Magic, and I was killed! They have to deal with all four CFWs and The Deity of Sin. We have to go now Eris, before it's too late." Eris nods, and they turned around and started walking away.

"Wait, Neptune-" Compa tries to say, but Neptune disappears into the void, and Eris disappears with a pulse of unharmful flames. Leaving the three perplexed people.

Nepgear didn't know what to do; they were losing and hard at that. It helped that CFW Brave had joined them, but even with that, they were still losing. Nepgear and the others were kneeling on the ground in pain well Brave was still standing. "I didn't expect things to go this badly," Brave says in a neutral tone. "It doesn't matter, and you will fall traitor." CFW Magic spat with venom, and she lunged at Brave however, she went around him was in front of Nepgear instead.

CFW Magic raised her scythe and was about to bring it down on her. "This time, you will die. You have no one to save you this time." CFW Magic said with a smile. "Nepgear!" The other CPUs called desperately to her. They wanted to move to save her, but their bodies wouldn't move from all the pain they were in. Brave could do nothing since his attack could hit Nepgear too.

Nepgear closed her eyes and stared at the ground, waiting for the pain… but it never came. Nepgear opened her eyes slowly and looked up. What she saw made her eyes water, and before long, she was crying. It was Neptune…. Neptune stopped the attack that would have ended her by grabbing the polearm.

With one quick swing Neptune punched CFW Magic in the chest, sending her skidding back. "N-N-Neptune?" Nepgear says In a quiet and saddened voice. Neptune turned to Nepgear and hugged her close. "I'm so proud of you, Nepgear. I know you will make a fine CPU, but I'm also sorry for leaving you and everyone else. now your big sister is going to take care of everything." Nepgear pressed her face into Neptune's chest.

Neptune smiled warmly and pulled away from Nepgear, but that smile was only for Nepgear and the other CPUs because when she looked at CFW Magic her smile dropped and turned into a sneer. Her eyes turned cold.

Cue Armed and Ready(from RWBY)

I Don't own the songs used in this they go to the respective owner.

To say the least, everyone was shocked, but CFW Magic was mad as all hell. "How the hell are you alive, Neptune! I watched you die! I killed you myself!" CFW Magic shouts in rage. Neptune just shrugs. She didn't seem to care for the CFW. Almost like she didn't find that magic was a threat. "Minor details. It doesn't matter." Neptune said absently

Ashes start to swirl around beside Neptune, and another girl with dark blue hair to the people, this was Eris. "So, what's the plan?" Eris asks simply. Neptune glances over at her partner "you deal with Judge and Trick. I'll take Magic myself." Neptune says in the same dull tone. "Any limits?" Eris asked. "Don't use our aces." Neptune says dryly. Eris nods and dashes at Trick. "Blackened Element: Celestial Shot" Eris calls out. The activation of the magic creates a blazing gun. The blazing gun was in her left hand.

Neptune stood there for a few seconds and shut her eyes. Allowing her void magic to cover her body, creating her void aura. Then she opens her eyes and calls out, "Blackened Element: Nova Crash!" Neptune jumped into the air and disappears, then she reappears. She releases a concentrated void blast. She lands on the ground and after starts levitating a few inches off the ground.

White Hearts eyes widen, and so did Green Hearts, Black Hearts, and Purple Sisters. They felt the raw power radiating off Neptune. "You must be asking yourselves what this power is and if I am Neptune. As I said, that day is true to yourselves, and nothing can stop you from moving forward." Neptune smiled warmly to White Heart and Green Heart. "Wish me luck…" Neptune says in a kind tone and disappears into the void.

Neptune gave CFW Magic no time to be surprised and charged CFW Magic. A sheathed chokuto appears out of the void and into her left hand. She drew the chokuto and swung the weapon at CFW Magic diagonally. CFW Magic sidestepped the attack and retaliated with a massive slash with her scythe. Neptune knocked the scythe to the side and used her sheath to smash CFW Magic on the left side of her head. Making her stagger to the right.

Over with Eris, she was easily dodging Trick and Judge's attacks. Eris seems to see their attacks before they were even given, placing her with the advantage. Eris shot three flaming bullets that burned right through Trick's armor and did critical damage to him.

"It's interesting." Brave comments. Black Sister stares up at Brave and hums as if she was confused. "With simply two people, the whole outcome of this battle completely changed. They must be powerful to take on three of the CFW's without having much trouble. Though I am pretty sure those forms are taxing on their bodies." Brave continued.

Green Heart joins the conversation next. "What do you mean taxing? They seem fine to me." Green Heart says. "No, they aren't Vert. Take a closer look at Neptune's stance. It's getting slightly limpish. Meaning that power does have its drawbacks." White Heart says in a stern voice. Brave nods his head in agreement. "Then what should we do? I can still move, maybe we should help!" Black Sister says, trying to be the voice of reason.

Black Heart cuts in next, "I appreciate your enthusiasm and encouragement, but Uni would you want to jump into a fight between the New Neptune, this strange girl and three CFW's?" Black Sister thought about that for a few minutes and then concluded that….. was an awful idea. "Now that I think about that. That is a pretty bad idea." "My point exactly." Black Heart says bluntly.

Before more could be said Judge was about to land a heavy attack on them. He went to swing the massive weapon down on them; however, before it could reach them, a light purple wall appeared above them stopping the attack.

The CPU's looked forward and saw Neptune with her left arm out in front of her. Neptune stood her ground and held the attack back with the wall but was slowly being pushed back. Using her right arm, she focused a lot of magic into her palm and creating an orb of void magic.

Neptune pushes Judge back with the wall of void magic, and it disappears after then she through the orb of magic at Judge, which hit him right in the chest, but that was just the start. It began to charge more magic into the ball, creating a Void Pulse Bomb. Neptune through a protective shield around Brave and called out to Eris. "Get over here, Eris! I just through a Pulse Bomb!" Eris's eyes widen, and she disappears into flames.

Neptune creates another shield protecting them "Everyone get down!" The other CPU's compiled. After a few seconds, a massive explosion happens, nearly knocking Neptune over. The magical shields go down. Neptune and Eris could see again they saw only CFW Magic remained. Eris deactivates her Blackened Element, and so did Neptune.

CFW Magic didn't give the two mages a chance to recover. CFW Magic swung her scythe, and it slashed Neptune's left hip. Neptune hissed in pain but followed up with a punch to CFW Magic's face, which staggers her again. Eris joins the assault on CFW Magic next. Eris took out her AW custom and shot the CFW in the knee, effectively making it useless, but before she could do more, CFW Magic slashed Eris twice, the scythe connected with her left thigh and her stomach. After that, CFW Magic swats Eris away with the blunt end of her scythe. Eris was sent into Black Heart, and the two of them hit the ground harshly.

Neptune took this chance to run her chokuto through CFW Magic's chest. The CFW returned the favor by running her scythe through Neptune's stomach making her cough blood up. The two separate, but CFW Magic fell to her knees as that happened. This time Neptune slashes the CFW's throat, killing her instantly. Neptune flicks the blood of her chokuto, and now all that was left was the Deity of Sin.

Neptune breaths out ragged breaths. Over with Eris, who was lying on a downed Black Heart. Eris slowly pushed herself off the Black Goddess. "Sorry…." Eris says in a pained voice. Eris stood up and helped Black Heart to her feet. Eris turns to watch Neptune slash CFW Magic's throat, killing her instantly.

Eris walked away from the group of CPU's and joined Neptune. "How should we do this, Neptune? I doubt our magic will be able to kill her." Eris asked bluntly. Neptune growled. "Your right. We only have one option…. Our curses." Neptune says back.

"Curse Seal Release: Curse of Elements!/ Curse Seal Release: Curse of Shadows" Neptune and Eris call out in unison. Black fire and black lightning appeared around Neptune, but instantly she felt horrible pain shooting through her whole body. Black magic seems around Eris, signaling her power overshadows. She, too, felt pain tear through her body from just using her curse.

Neptune charges The Deity of Sin and strikes it creating an explosion of black fire. It instantly shreds through her power that makes her a goddess but not enough to make her lose that power.

"What did you just do to me?" It asks in anger. "You're feeling the effects of my curse. It slowly kills you and takes what makes you unique. In other words, it is taking what makes you a goddess." 'Though it hurts us to use it. I am trying not to throw up blood all over the floor, ' Neptune thinks grimly.

Eris glanced around and drew her AW custom. She shot four bullets infused with shadow magic. It moved so fast it looked like a black line that went straight through the Body of the Deity of Sin.

It was sent skidding back from the shot, but the massive beast retaliates and smashes its fist into the ground where Eris stood. Still, she teleports using her fire magic before the fist can connect with her however, another one of the arms smash into Eris sending her flying.

Eris flips around in mid-air and lands in a crouch a reasonable distance away from the Deity of Sin. Then she watched as Neptune went into Nova Crash again and releases a massive blast of void magic, but what she earns for her efforts is getting backhanded by one of the four arms the Deity had sending Neptune skidding back.

Eris shot five lines of black magic, but they do little damage but don't need to do all that much damage. It just needs to connect.

An hour of fighting later. Neptune and Eris had finally taken The Deity of Sin's goddess power away with their curses but around halfway through the fight. They end up throwing up blood multiple times. At this moment, they were looking at Arfoire. Blood was dripping from their left nostril and the left side of their mouths.

"How? How did you do this?" Arfoire asked in anger. Neptune's and Eris's curse magic faded away. Their magic couldn't be used since the side effects of their curses seal away their powers. Breathing heavily, Neptune glares at Arfoire "you simply couldn't resist our curses, and now you will fall to it. We may have used it too much that it canceled out our power, but in the end, you will fall to us." Neptune says in a dark tone.

Arfoire roars in anger and charges Neptune. She jumps due to being unprepared for the charge. Arfoire stabs Neptune in the ribs with her spear, and it barely misses her lung. Arfoire tore the spear from Neptune's chest and turned around to continue her assault but was met with Eris's AW Custom pointed at her chest… directly at her heart.

Arfoire glares daggers at Eris, and she pulls the trigger. Eris shot Arfoire straight through the heart, killing her instantly. Arfoire's lifeless body fell to the ground and was quickly incinerated by Eris so she couldn't come back. Eris looked at Neptune's limp body lying in her own pool of blood, and she too joins her as she fell unconscious.

End of Armed and Ready

After the crazy battle finishes, Nepgear and the other CPU's left HDD. Nepgear had so many thoughts going through her head. Not just her but everyone for that matter. Everything points to the fact this couldn't be Neptune from her attitude to her power. Their guts told them not to trust her, but their souls told them it was her, and they should trust her.

They didn't know what they should choose, but Nepgear did. She trusted her soul. "We should help them. We can decide if we believe this is Neptune in my Basilicom." Nepgear says absently. Since her voice didn't sound like this was her asking, the other CPUs didn't argue with her. So Noire picks up Neptune, and Vert lifts Eris off the ground.

It took around an hour to get back to the Basilicom and when they got there. They found the guard posted in front of the Basilicom on the ground. That stops everyone in their tracks, and Nepgear went over to him and checked his pulse.

Thankfully she found one and sighed. "this guard is alive just unconscious," Nepgear says in relief. "Were going to have to come back for him," Uni says rather bluntly. They opened the Basilicom door and went in. After getting in, they started looking around. After a few minutes, they located If, Compa, and Histoire.

"We're back, Histoire!" Nepgear shouts. This caught the attention of the three that we're talking about something. When they peer at the group of CPU's, they noticed that Vert and Noire were carrying Neptune and Eris.

"Are they-" Compa couldn't finish her sentence as Vert interrupts her. "They aren't in the best conditions. Neptune's injuries are likely the worst. I'll let you take her from here. The girl with the blue hair is in a similar condition, but I can't tell you much on her wounds." Vert explained and gave Neptune to Compa. Compa nods and motions for Noire to follow her. The two of them left the room next.

Vert sighs and hopes Neptune would get better If looked conflicted before she spoke. "This is a huge confusing mess. How is Neptune back from the dead?" She didn't get a response since none of them knew the answer to how or why she was back.

"So, what happened when Neptune got there?" Histoire asks. This confuses most of the people there since they didn't know Neptune was here before going to help them. So Vert explains to them.

"So, what are your thoughts on Neptune?" Histoire asked seriously. Blanc shut her eyes and thought for a moment. Then she opened them and looked at Histoire. "In all honesty, I think it's her. She knew what she told Vert and I, and She apologized for leaving Nepgear and the rest of us. Her actions towards her also says it has to be her." Blanc says seriously.

"Your thoughts on Neptune? Uni, Nepgear, Rom, and Ram." She got similar responses from them. Neptune had been acting slightly different, and the new power but their souls told them that she was Neptune. Noire walks back into the room, but Compa wasn't there.

She asked Noire the same question, and she still got the same answer. "So, we all believe it is Neptune?" Histoire asks. She reserved nods all around her. "So, do we have any leads on why she passed out like that?" Rom asked. "Well, judging on how Vert explained things. I have a theory. I believe that she uses something similar to Shares. In a way, her power called Nova Crash has to draw on something inside her. It could be shares, it could not, but I doubt that was the reason she passed out. I believe her cursed magic was the reason she did. From what I can understand, it has a drawback and a huge one." Histoire explains. After around an hour later, another voice broke the silence.

"Your theory is true, correct. I use magic to power my Nova Crash; however, my curse is a different story," A Voice in the doorway says. They all turned to the door and saw Neptune, but Compa was trying to hold her up. Bandages were covering her torso, and both her arms were covered in bandages.

That wraps up chapter one. Now I will state you will see Neptune during her time in Citadel. It will only be in flashbacks. Since that part of the story is probably the hardest to understand. It is entirely unrelated to HyperDimension Neptunia. So I'd rather keep that stuff down to the minimal, but I will show enough for you to understand what happened there.

I also would like to know what you would like to see Noire x Neptune, Blanc x Vert or both in the next chapter. Blanc x Vert will have a flashback show how they started dating.
