Chapter 1: The Goddess of Planeptune and the Visitor !?

Summary:

The Events that start this whole chain of events changing the course of events from the official release.

Chapter Text

~~~[Planeptune; The day of the Peace Treaty Ceremony]~~~

We open up this chapter with the events of the Peace Treaty going on, including the whole scene from the original episode of the anime. But, as we are seeing the events unfold the scene is shown to start being glitchy as we are seeing a strange phenomenon going on with the Reality of the Dimensional devide of two different worlds.

 

~~~[In that other World; Home Dimension of Akira, some time before his Transmigration to Gamindustri]~~~

 

We see my original character Akira with a sword trying to fight against a being that was shattering his Dimensional existence.

 

Akira: .... Raaagh !? ...... (Damn it, this thing is to strong...... I can't beat it like this......)

 

Inner Akira: ....... We can't win if we don't do anything for more power. But...... You're refusing is getting in the way !!

 

Akira: ..... I'm not using that power. Not even sure how I got it in the first place...... You're not real, how can you be.......

 

Inner Akira: The resistance of self is not going to help you, you have to see the truth. Don't you want to he yourself !? Stop pretending you aren't closing off to who you truly are !!

 

Akira: I told you to be quiet !!

 

The creature that he was fighting started to damage the Dimensional plane on which Akira lived more and more. His world is being lost, all because of his own refusal to accept that he is hiding his true self.

 

As he tries to fight, the world was falling apart yet he refused to let his inner self convince him to use the power he was given. Eventually, his Home Dimension is erased and he ends up going through a void between worlds.

 

Akira: (I lost..... There is no going back......)

 

Believing himself to be dead now that he was in the after life he was just accepting that he lost because he couldn't win the fight. Still refusing the power that was bestowed upon him, but when was it given to him you may be wondering......

 

~~~[A few years ago; Akira's Home Dimension, before the events of Erasure]~~~

 

Akira being the last person that can interact with the power that was used by the old leader of his Home Dimension and the nation that made it up. He was told he had to take in the power, when he did a mark resembling the icon seen on a power button showed on the back of his hand.

 

He was not very accepting of the power though as he knew that only women were accepted as the protector so he would never be able to use the power like she who had it last.

 

Citizen: Why are you not using the power ?

 

Akira: I don't deserve it...... Men don't usually have the right to use this power...... You know this, so why...... Why does everyone expect me to use it !?

 

Citizen: Because it was given to you. None of us have the ability to interact with the power..... You were given the gift of the ability to interact with it.

 

Akira: ....... I don't...... I can't accept it.

 

That was when his inner self surfaced within his mind the voice that knew the truth.

 

Inner Akira: It's true, this power was waiting for someone to come and accept it into themselves. Yet..... It was someone who can't accept themself.

 

Akira: I......

 

We return to Akira's present time as we see him accepting his own death, but before he could even think another thought.

 

~~~[Present time; The Moment Akira crosses over to the Dimension of which the anime takes place]~~~

 

He drops out of the sky in Gamindustri and ends up landing on Noire the Goddess of Lastation upon his entry to the world that I have decided to call Hyper Dimension Variant B aka the anime version.

Noire: .... Rrrrgh...... Are you serious right now !?

 

Neptune: Whoa, that's not the first time this will happen..... And probably won't be the last either.

 

Akira: ..... (I'm alive, oh ..... I'm alive...... Well..... That was anticlimactic.....)

 

Akira is not able to get over the fact that he was just pulled out of his one way ticket out of his situation. Yet still, things were only going to get worse in his eyes. He meets the Goddesses of the world he had just came to, he definitely wasn't happy to be still alive.

 

Akira: Why am I still breathing ? I thought I was supposed to die back there.

 

Neptune: Uh oh, he's gotta be one of those edgy OC guys people made for series. Eh..... At least he's only in this story. So..... You gotta a name ?

 

Akira: My name is Akira, I don't know about why I'm still alive right now. But....... Why do I have to live ?

 

Neptune: Will you ease up on the edgy speak. That's not what the audience is here for.

Akira: ...... What audience ?

 

Neptune: Any way.....

 

Akira: Don't dodge the question !?

 

Noire: Rrgh..... First you come here and nap in my Basilicom, now this.

 

IF: Well, we did come to get some Goddess training for Nep. Why don't you just have her so some requests that are available ?

 

Noire: Oh.... I forgot about that.

 

Like in the official anime episode Noire gets some quests and the exact same thing happens for the most part but with Akira present. The party is formed for the quests from here on, Akira going with them for now because he otherwise he'd be alone.

 

We see the events play out like the original episode with Uni telling Noire that nobody was listening

After that, Noire ends up poking Neptune in the butt for walking to slow. As they soon approach the village near the Nasuume Highlands, Noire runs up to the edge of a cliff and waves to the people.

She than notices she forgot something, intiating her transformation sequence.

 

Noire: ACCESS !!!

 

Neptune: What !? You're transforming now !?

 

Noire's transformation sequence plays out as seen in the anime, Akira has a bit of a shadow over his eyes from his hair and he grits his teeth.

 

Akira: ..... (That power......)

 

Black Heart: Rule 1 in the Goddess handbook, you must always project a majestic air.

 

Noire starts flying to the village and speaks out to the villagers to give more information on what they needed help with.

 

Neptune: I don't see how getting naked in front of strangers is majestic......

 

Compa: Hey, is something wrong ?

 

Compa was looking right at Akira who had a bit of a scowl on his face now. He snaps out of it and looks at her, he looks away and follows the others and speaks back to her.

 

Akira: Don't ask, it's nothing that concerns you. Not right now, at least.......

 

The events continue on like the anime, Akira watches on the sidelines while the fight is happening.

Akira: (Dogoo aren't as pathetic as she thought now aren't they ?)

 

The fight went on for a bit longer until something changed that alters the course of events from how they are supposed to go. Akira recognized the strange phenomenon going on with the Dogoo as well.

 

Akira: ..... No, it's the effect of......

 

Inner Akira: We gotta use the power, we have no choice.

 

Akira: I...... I don't want too....... But........ I don't have much of a choice anymore......

 

The mark on his hand glows as he lets the Share Energy the same power that Noire used to transform started to manifest from the mark. Upon letting the power be used by himself, he goes through his own transformation sequence.

 

His body becomes more feminine and gains a larger chest that shows how mature this form is. His normal clothes digitized off and he gains a Techno organic Processor suit that was similar to Noire's, yet with Red accents rather than Noire's silvery ones.

 

Black Heart: What !?

 

Akira uses another ability of his to accelerate his movement to be nearly to fast to know he was there. But, the ability deactivated after a few seconds due to the fact it takes to much power to use it.

 

Neptune: NEPU !? When did we get more back up ?

 

Nepgear: Who in the world ?

 

Crimson Heart: ........ No time, we need to finish this quickly. Before that thing Gets to strong.......

 

IF: Rrrrgh...... Here I thought we were done after I took all of those freaky Dogoo.......

 

Neptune: What, there's more !?

 

Crimson Heart: It's you........

 

????: You really thought, you could just love a brand new life and forget that I always come back to ruin your life !?

 

Compa: Who is this ?

 

Crimson Heart: She's the reason I'm here. The one that ruined my original world. After she murdered the true guardian of my world......

 

????: My name doesn't matter right now. After all...... It's not time for me to end my existence just yet.

 

Neptune: End your existence ? This sounds like more edgy scenario business again, I don't like it.

 

????: Don't worry..... I'm not going to do anything, yet. But..... Just know that working with him..... Isn't going to work well for you Goddesses of Gamindustri.

 

Crimson Heart: Arcadia was lost because of you !! Do you think I'm going to just be able to let you exist like this !?

 

????: I expected this...... After all, I killed her in front of you and that was when you made the link to the core of the city...... The power you now use.

 

Black Heart: Who ever you are, I don't have time to talk about your stupidity..... So leave before I show you why you are making a mistake !!

 

Crimson Heart: .... No, you stay out of this. I don't want it to happen again....... I don't want a Goddess to die because of me starting a fight that.....

 

????: That's right....... The Goddess of your home world..... When I killed her she was so adamant that you live..... Yet..... Her life force didn't die..... Only her physical self died......

 

Crimson Heart: ..... !? What are you talking about ? She...... She's alive some how !?

 

????: Well, of course she is..... I'm looking at her.

 

Crimson Heart: W-What ? No...... I'm not her...... I.......

 

Akira sees his reflection in a shard of broken weaponry from his attack that broke when he tried to strike his enemy. His eyes go blank in horror, somehow this was the reason he had.

 

Crimson Heart: Is this some cruel joke ? My power turns me into the spitting image of her...... But, why !? Why does my consciousness insist on taking her face !?

 

????: Because...... You're not a being that was separate from her...... You're a part of her that was broken free when I killed her.

 

Neptune: Jeez, this really is an edgy background.......

 

Crimson Heart: I think I get it...... The Goddess of Arcadia...... My home....... She put her spirit into my body...... That's why I have this power !!

 

His weapon repairs through a digital effect and he summons out another blade. The figure who told him this, warped away from the scene and her voice in an echoed phantom sounding voice.

 

????: You never should've been there. Because if you weren't...... She'd be dead, you would've had a normal life...... This would not be your fate.

 

Crimson Heart: ....... If this is my fate, I can't refuse it anymore...... If I'm to be her continued life...... I won't refuse......

 

Black Heart: Rrrrgh..... If you're quite finished, we are supposed to be going to the Cavern next....... But..... Due to Neptune not taking things seriously, I'm going on my own.

 

The rest of the events continue on as intended from the original episode from here, with Neptune saving Noire from an Ancient Dragon and all that. But, we confirm that Neptune still had the images sent to herself.... Or rather all of the Planeptune population.

As for Akira, we see that he had no money to stay anywhere so he ended up staying in an abandoned facility in the Planeptune area.

We close this chapter with Akira alone and unsure where fate will lead him next, the knowledge his nemesis is here in this world and that the Goddess that died in front of him is part of his soul now he sleeps slightly more peaceful than he would otherwise.

 

~~~[Meanwhile; back in the Very cave that Neptune and Noire were in]~~~

 

We catch a glimpse of a rodent and a witch collecting the gem that had broken Noire's power connection apart. Arfoire and Warechu are up to their. Plan as we know..........

 

~~~[Meanwhile still; In Lowee]~~~

We catch a glimpse of Blanc busy on whatever it is she was working on --- it's her Book --- as we wait to see what happens next.
