Author's Notes: A Cracked /Serious(?) Fic? Thank you, Catherine, I love you too. This crossover takes place after Minami Ikoma's capture but before Hinaga Rieko's capture at the start of Summer Break.

Author's Notes: This should be written long ago, by someone else. Harem route(?) as the final goal here!

Note 2: I only cleared Neptune's route, so I will be taking liberties with that route more.

Let's produce perfection!

Also, thank you, bowpurity for beta-ing and being patient with me.

..

Katsuragi Keima, the Capturing God was taking a well deserved break after shutting his adopted sister and menace to his life, Elysia de Rux Ima or Elsi in short, in her room before dead bolting his own room to allow him peace and quiet.

He had been forced to go through one too many missions for the real of late, there was no way that he was going to get tricked into another situation like this now– not when it's summer break. Not when his title of Capturing God was on the line. He had planned everything out, even getting his games sent directly to him despite the extra cost. Earlier on he did his final checks.

All the batteries were charged, the consoles were plugged in safely and his rations were placed strategically beside him when he would need recharging from his planned 14 days marathon of all the games that had just been released which would keep coming if the release schedule did not change. He would be drowning in an unlimited circle of new-releases till the two weeks were up if all goes according to plan.

Which, Keima strongly suspected – would not be the case. The real would have more in store for him, he was sure of it. But he was going to struggle against the fate, he denied it! He would!

'I will not bend my head to the real, mark my words.' Keima scoffed before selecting the first game for the day, he hoped to be the first of many!

His hand touched the box art, and was promptly sucked into the box without any prior warning.

What will the Capturing God do when the Ideal wants him to help? What then?'

..

Keima felt that he was falling, and as one who has prior experience with falling – what with him diving from the top of the school to save Tsukiyo, he did not panic. He only felt resignation that something else had decided to sought him out for his assistance, again.

No way, he was not going to help, no matter what!

Keima barely had time to get that thought out before he crashed landed on a body, several bodies actually and the Capturing God, dusted himself off patiently after helping himself up from the four bodies that had helped to break his fall. They were all girls with exotic hair colors, which by itself set him off. They were either cosplayers or demons, only supernatural beings has unnatural hair – Kanon was the exception to that, but he was sure that Kanon wasn't a natural strawberry head.

Then again, he had seen odder things in the world so far after dealing with Elsi and the Weiss Capturing Squad – so this was nothing. He had grown over the past few months with the Weiss Capturing Squad, nothing phase him now.

He hoped at least...

'Owwwie!'

The girls groaned in pain as they helped themselves out, but they looked all none for the worse despite having someone dropped down on them from quite a distance. It had felt like twenty seconds, which meant had been dropped from quite a height.

'You're... our producer? You look like a cut and paste stereotype, but okay! Nice to meet you in your face!'

The first girl to speak was the one who had recovered the fastest. She was the shortest of all of them and had purple hair while wearing a purple and white striped hoodie. With her cheerful and energetic smile combined with how she was literally bouncing on the balls of her feet, Keima tagged her as the optimistic and genki girl right off the bat. She was blunt too, but Keima thought there were worse ways to introduce himself, like how he did – which was to simply nod in understanding before pushing his glasses up the bridge of his nose and looking around sternly, trying to memorize the layout. By a minor miracle he was still wearing his glasses, if they broke – he would be in a bind indeed.

'Who are you.' As the other girls recovered, gathering around the first girl, he asked quietly.

'We're... well, to you, we'd be called goddesses. Something like that was nothing for us.'

Another girl spoke, this time one with black hair that was tied up in twintails, she sounded haughty too and the way she puffed her chest up and looked proud to show her status of a goddess to another, she was the proud and sensitive one.

The fact that she had called herself as a goddess with a straight face was not lost on Keima, either that was the truth or he was in the middle of a cult. Both – does not bode well.

'We rule over this world, [Gamindustri], as it's goddesses. We're called CPUs – Console Patron Units.'

The third girl, one with short brown hair that was topped with a large beret answered softly as she scrutinized him. Keima was well versed in the art of reading a person through their expressions, and from the lack of expression from this one, she was the reserved character here. But it was the term that she used that made Keima focus a little bit more. [Gamindustri]? He wasn't in earth now? He was in a game then? Or another world. This... wasn't good – or it could be amazing, he had not made his mind up yet.

'We're in a bind, so we summoned you.' She finished before looking expectantly at him.

..

'Yeah, I getcha, you feel like a duck out of water, right? We're gonna go ahead and explain things nice and slow.' The purpled hair girl smiled encouragingly while speaking in what Keima assumed as her reassuring voice. They must have mistaken his calmness for shock, hmph, did they expect less out of him, the Capturing God?

'Lemme introduce myself. I'm [Neptune], the CPU of the nation [Planeptune].' The girl, now introduced as Neptune grinned as she waved at him eagerly.

'I'm [Noire], CPU of the greatest nation in all of Gamindustri, [Lastation]' The black haired girl smiled proudly again as she brushed her twintails back – Keima had her pegged from the start, this was the proud and arrogant girl, he could ascertain it now and save the trouble for later.

'I'm Blanc, CPU of [Lowee]. Lowee is the greatest nation in all Gamindustri. Don't get confused by someone else's lies.' The brown haired girl cut into the conversation aggressively, her eyes burning in eager anticipation of the competition. Keima had her pegged right too, she was the reserved character but as expected; that was not a true reflection of her nature. Deep inside she was one who had the most to say, and most to express to the world.

'I'm [Vert], the CPU of [Leanbox], and the one who possess the most voluptuous breasts in all of Gamindustri.' The last girl, the blonde that looked the part of the big-sister type introduced herself with a saucy smile, puffing her chest in triumph against the rest of the younger girls. Keima's lips quirked a little as he saw the other three girls scowl a little at the now introduced Vert.

..

'Woah, let's not rustle our feathers during introductions! Vert's rack has nothing to do with her nation.' Neptune rushed to stop the growing aggression between the girls by raising her hands in the air to gather their attention to her. Keima was impressed, despite how she looked and acted like the most childish of them all, she could be the leader as everyone followed her lead.

'Anyway – Vert, get on with the explaining. Because, uh, because I don't really want to.'

That was Keima's thought till Neptune asked Vert for the explanation sheepishly. Keima supposed that was per her character, but from how he hadn't been able to get a word in at all – not that he wanted to, he's going to have his work cut out of him if Neptune was indeed the leader of this group of woman.

What were CPUs in the first place? And where was he? Why was he here? If this was New Hell, he was going to strangle Elsi's boss.

'Producer, are you fine?'

Vert must have noticed his sudden lapse in attention as she rested one hand on his shoulder, frowning more as he jerked away from her in reflex. Producer? Did they need a producer? That was a question for later, right now – explanations.

'I'm fine. You were about to explain?' Keima asked and Vert gave a long suffering sigh as she turned to Neptune.

'Why must you push the troublesome task on me?'

'I mean, explanations sound like they should ooze from the mouth of a kind, big-sister-type like you, Vert.' Neptune quipped with a straight face that definitely made Keima give a faint smile.

His amusement increased when Vert understood and didn't seem to mind at all. These girls were familiar with the ideal than. Perhaps, this wouldn't be too bad, unlike that failure of a demon.

'Oh, I see. Then allow the most mature among us, me, to explain things on behalf of these three children.' Vert smirked and looked very pleased till Blanc commented with a conspirational whisper that was heard by everyone present.

'You're the old one, not the most mature.'

Vert visibly deflated, looking quite depressed for a moment, but she still cleared her throat after glaring at Blanc, who was smiling at her. Thankfully none of her ire was directed at Keima, and the Capturing God took a moment to reflect on the girls that had just introduced themselves to him.

They were close, that much was sure with their familiarity with each other. The chance that Neptune was the leader was decently high, although he did not know why they would follow someone who behaved like a child most of the time.

All of them appeared to be at least knowledgeable and they lived in a world called Gamindustri. That was all he knew, but he could make a few accurate guesses based on the ideal. But goddesses? That was pushing it a little, wasn't it?

These girls were the ones who summoned him and they would only do that if they required his help – that was the ultimate rule of the ideal.

In a perfect and flawless world, there wouldn't be a need for external help when everything was perfect. The question now was what was the impossible task that they expected him to be able to do. Whether he could achieve it as irrelevant - he was the Capturing God, but he had already been asked to do the almost impossible for the Weiss Capturing Squad, what more must he do now?

..

'As I was about to explain... Gamindustri consists of four nations.' Vert gathered their attention by coughing again and all of them nodded before settling down to listen to her.

'The four nations are: Planeptune, Lastation, Lowee and Leanbox.'

Keima nodded as he filed away the information to be used later.

'Each nation has a [CPU] dedicated to protecting their lands. They protect others using the power gained through the people's faith, known simply as [shares].' Vert continued and she seemed to one to go into further detail before being interrupted by Noire who winked before exclaiming something that made Keima pause.

'Like we said earlier, we are those CPUs who protect our nation, check this out!'

Before Keima could properly register the term CPUs and shares, the four girls were covered by flashes of light. Keima fought the urge to retort that at the very least they did not have an impractical flashy transformation sequence, but that was something for another day.

When the light faded, instead of three young woman with a full bodied one, Keima was facing four mature and confident woman wearing armour that would be at home with the ideal.

'How's this!? This is my Hard Drive Divinity form, HDD for short. In this form, you will call me Black Heart.' Noire, or Black Heart he supposed, preened proudly while laughing in glee. If he wasn't imagining it, he'd say that White Heart was drunk with her power. Keima figured that this was gamelogic, stripperific armor. He was beginning to have less doubt that this was the ideal after all.

Black Heart had long white hair while dressed in a skintight, black and silver colored futuristic armor. However, the outfit looked disturbingly more like a swimsuit in his opinion. Stripperifc armour, much? In any case Black Heart's outfit left a sizeable portion of her chest for all to see and with her shoulder exposed, it left him contemplating how fanservice has even penetrated this world.

There was also the edge of danger about her presence though, one that screamed power. It was similar to what Keima had felt when facing against the Weiss that had taken control of Haqua, that oppressing feeling then was nothing compared to what he felt from White Heart though.

Perhaps they weren'texaggerating when they said that they were goddesses.

'I am Purple Heart in this form. Since you have seen us transform, we cannot let you return home.' Neptune, or Purple Heart spoke sternly as she crossed her arms, studying him closely.

Purple Heart had a total change of character together with her body as compared to Noire, enough for Keima to raise an eyebrow in surprise at her. At least Noire retained some of her arrogance, only she was more, vocal with it.

Neptune however took it towards the other end of the spectrum. The woman, yes – she was a mature woman alright that had her purple hair grown out in long braids looked and felt different from Noire.

She was dressed in a similar styled armour/leotard, only in purple and black and was a little more covered than Black Heart was. She, too, did not have straps supporting her bust line but unlike Noire, she pulled off the serious look much better. Keima understood why she could be the leader of the four goddesses, if there was such a thing.

'We took so much effort to summon this person, and you both just... ugh, I'm White Heart. Don't forget it.' The third member of the party, Blanc, introduced herself as White Heart with a drastic change in her voice and volume. Gone was the quiet and perhaps even a little meek voice of Blanc, she now spoke with confidence but was more akin to growling than actually speaking. Keima could sense aggression even when she was not doing anything.

White Heart's appearance was different as well, she could be considered mature by the sheer virtue of how she carried herself. She was confident, radiating power like Black Heart did. Keima had to appreciate that, especially since her hair joined the outlandish crew by being colored blue now. Unlike the rest, she was dressed in a skin-tight swimsuit– yes, he had to call it a school swimsuit for the sake of his own sanity. For his physical well-being, he refrained from commenting as she glared at him and the other two goddesses.

'And now we four have transformed and are surrounding this unknown person... I wonder... have we made a mistake?'

Purple Heart interrupted the conversation by scrutinizing him closer, again, and Keima simply gave a small scoff as he met her gaze resolutely without flinching back. His reply through that gesture alone made Purple Heart pause before she nodded back, a sign of approval.

'Ahaha~ You're so calm after you transform. I can never tell if you're kidding around or not.' Black Heart laughed again as she smiled at Purple Heart. The latter did not even reply or acknowledge her fellow goddess, making Black Heart bristle a little while Keima watched on. The dynamics of their relationship was being more and more apparent, he could, see the ending quite easily now.

'Should we show off our power by hammering it into your organs?'

White Heart growled again when it became apparent that Purple Heart was ignoring all of them but him, he should be flattered – if not for how they might start a fight with him as the centre. Admittedly he would be prepared for it, but still...

..

'I am Green Heart. Because of their immaturity, those three have shifts in personality and looks when in HDD mode. If everyone continues to mess around, we will frighten our dear producer. Let us return to our human forms.'

The only voice of reason, the busty Green Heart that was Vert smiled sternly at everyone while resting her hands below her chest like how a true 'ojou-sama' would do.

Green Heart's personality did not change just like how she had said, but she looked totally different. Besides her striking green hair which was tied up in a long ponytail at the top, Green Heart's was literally wearing a black colored thong in her goddess form.

That was fanservice overload...

Keima had to pinch the bridge of his nose to stop the pending sigh, it would not be good to show her frustration so openly to a group of so called Goddesses as they returned to their original human forms.

It was difficult to really view them as goddesses in this form, compared to their HDD forms. Keima had to agree that if they were superheroes trying to hide their identity, they were doing a good job of it.

'And that is how things are. Do you understand that we are goddesses to you, now?'

Keima nodded his head to let Vert continue on, it wouldn't do for him to interrupt them. Best to clear out all his questions and frustrations in one shot rather than to get interrupted later on.

'Normally us four would be fighting it out for control of the world's shares, striking a peaceful balance, but... Gamindustri is currently having it's shares allocated to pop idols, and not to us.' Vert explained before allowing Neptune to elaborate.

'We're losing the young'uns. It's kind of a big deal.'

'If we continue to lose shares, we won't have the power to keep our nations safe.' Blanc chipped in with a frown, looking the most upset she had been so far.

..

'That is why we have decided to knock our opponents down to their knees and show them what a true idol is like. It is our first attempt at becoming idols, so we summoned you to help us. You are an experienced producer, no?' Noire frowned as she stared at Keima, her eyes daring him to say no. Keima for his part, was unphazed. If he could stand up to Purple Heart with her carefully crafted calm that still reeked of danger, Noire's attempt to intimidate was nothing.

'Since you were summoned by the power of the four CPUs, you should have the ability within you. Will you do it?' Blanc continued on with Noire's threat and she pulled it off much better than the black haired girl. So, there was no visible response from him as well.

'So, um, you can't really say no. We brought you here, so you're gonna be our producer. Them's the breaks.' Neptune smiled apologetically in what Keima hoped was a sincere smile as well as they waited for his answer. Or perhaps wondered why he had said much at all up till now.

'Uhm... are you okay, Producer?' Vert asked, this time in concern as she raised a hand to get the other girls to wait and be patient.

'You can take your time to think about it... I understand it's hard for you to accept at one time, but we, really need your help. So please, say yes.'

Waited – he had to give them some props for allowing him to think about it for a moment he assume. But it was like Neptune said – and Keima reiterated again as he replied them,

'It is like you said, I cannot refuse, you are the ones who brought me here, and therefore you are the only ones who can send me back. In light of that, is that not threatening me?'

Keima asked patiently with a straight face that made Neptune squirm, Vert frown, Noire surprised and Blanc start to get agitated.

'It is nothing but the truth, so I see that the goddesses of this world think nothing of taking a stranger from his own home without violation before threatening them to do a duty which they are not obliged to do so.'

Keima was ruthless with his words against the four goddesses, he suppose he was being rude as Blanc lost her temper, but nonetheless she held it in as she bit her lip in frustration. The truth of his statement must be holding her back, that's good, the goddesses were not the dominating and warlord type like he had pegged them be.

Neptune looked taken aback, but she rallied easily enough and looked ready to defend her actions while Vert and Noire just looked away, probably ashamed at herself.

'And all of you have the cheek to expect me to accept this farce of a negotiation without raising a single objection? This is not what I expect from a goddess, especially when you said it yourself – you are the ruler and keeper of an entire nation. If this is the extent and the way a goddesses' seek to protect their nation, by kidnapping someone unscrupulously and demanding them to help them – perhaps the people are right to lose faith in the four of you. If the four of you are truly the goddesses which have protected their livelihoods and their lives so far, you would not be in this predicament. The mere fact that you have lost support to the real like idols is laughable. How can idols take precedence of military might and power?'

Keima knew that by saying this, he was pushing into dangerous territory, but he had to be blunt to hold some sort of power over the four goddesses. Were they really goddesses? Perhaps, but he was the Capturing God – he was a God too!

His words made Neptune pause, but the other three goddesses had slumped, most likely embarrassed by what he had said.

Noire's mouth was open and closing like a goldfish, she was obviously stunned by what Keima had said and was unable to come up with a comeback.

Blanc was simmering with anger, gripping her own hands in frustration but she too said nothing again. It must have struck a nerve, but due to how he was right, she couldn't retort back. Good – he had some respect for Blanc in accepting her failure.

The same goes for Vert, the blonde had a look of resignation on her face and she bowed her head in apology to Keima when she noticed her eyes on her. Like Blanc, his opinion of Vert increased as well.

But that was nothing compared to Neptune – who stood up and looked at him straight in the eye.

'Would you, please?' Neptune's question left Keima incredulous even as she continued.

'You're right, we really are in a bind, that's why we asked for your help, and you're right too – maybe we are lousy goddesses. But that's why we need your help, please. Pretty please, with a cherry on top? ... you hafta believe us, but without us four goddesses, Gamindustri will fall apart. I'm not the, well, best goddess or anything, but, I try my best all the time – most of the time. Our best isn't enough this time! So we have to ask for help, asking for help is better than not, right? A-And you're like a hero, right? The hero who was summoned with awesome abilities we don't have. So... please, like a hero, help us? Help Gamindustri? I don't know what you want, or what we can give you, but if you'll just he-'

Neptune was stopped when Noire stood up beside her as well, she putting a hand on her shoulder before pushing her down forward in a bow.

'… Ugh, although I hate to say it, the both of you are right... I, well, we're sorry... we shouldn't have... just, said it like that... even if we are, goddesses.' Noire mumbled, but the humbling act of bowing to him was enough to settle some of his anger at least, especially when the other two goddesses apologized and asked him for his help as well.

'As the CPU of Lowee, I, Blanc, would be in your debt if you...lend us your aid.'

'I as well, Vert, CPU of Leanbox, pledge herself and her nation's eternal gratitude to you if you could assist us and help us gain our shares back. We goddesses would not have done so if we could think of a solution, please pardon our... ignorance of the matters.'

Katsuragi Keima gave the four goddesses another scathing look before replying, most of his anger and rage had been taken off due to the goddesses apologizing to him.

'Like I have said earlier – I too am at your mercy. Make an unbreakable promise to me that once I have accomplished my mission, that you would send me back to where I came from, and at the exact moment when I had left. While I am here, you will also protect and take care of my needs and the necessary equipment to fulfill your dream of becoming idols. I had planned for a week for my gaming marathon. I refuse to give that up.'

Keima scoffed as the four goddesses looked at each other, looking awkward before Vert replied.

'At the same time? We can't promise that, unfortunately...' The four of them looked nervous but they gave a sigh of relief when Keima nodded his head.

'Understandable, I will accede that point if there is a limit to your abilities, what of the rest of my conditions?'

'We accept, it is more than reasonable within our means.' The goddess nodded their head before Neptune continued.

'So... you are, an awesome producer, right? You have to be... right?'

Her question caused Keima to scoff as he pushed his glasses up the bridge of his nose.

'Goddesses of this world is amazingly naïve, why have you not checked on my identity before agreeing to my demands?' He allowed his statement to sink in before he raised his hand in warning to stop the burst of outrage against him.

'I will achieve your dreams within 90 days, that is a promise, from the Capturing God.'

'Capturing God?' The goddesses were prevented from showing their displeasure by the sheer aura of confidence from Keima as he smiled thinly and challenging at them.

'Now then, as your new manager, I would need more information about Gamindustri – what is it, what I can expect, how all of you would wish to be named, where would be our base of operations...'

..

The day where the HDD Goddesses meet the God has finally arrived.

'Let's all become Idols!'

..

To be continued...?

To be continued? I'm still deciding - let me know through your reviews!
