´´´´ Inner thoughts
Space, since immemorial times sapient species had been always fascinated with its concept, the great unknown, the last frontier, a place full with as much opportunities for immensurable progress for civilizations, where impossibilities are made real for anything, were the hopes and dreams of any sapient species can become true as it is also the same place were untold ancient horrors dell, awaiting to be unleashed on the unsuspecting and naïve ones, be there other aliens, machines that have risen against their creators or simply its vastness that isolate members of the same species. A frontier were salvation and danmation can be gained in equal measure.
However outside of space, another frontier exist, this one truly unknown for many and yet contains many of the greatest dangers of the universe, the inmaterium, the realm of souls, the warp. A realm of pure physic energy, were thoughts, aspirations, fears, nightmares and souls of living things combine. A realm were unimaginable horrors coexist with the cycle of death and rebirth of all sapient beings in the Milky Way galaxy, inherit to every intelligent species with a soul.
The power and influence of the warp is a true for any species, but perhaps this is more so for humanity who had risen and fallen countless times through the vastness of time across the void, who despite from its inherent dangers have relied on it for their expansion across the galaxy, their communication with each other and some of its more important scientific progress, despite not having a fully understanding of its true dangers, as malign entities inside of it plot the corruption and destruction of all life in the material universe in the name of their great game, aided by their daemonic servants, looking to claim mankind soul without them noticing their full extent of their power and influence, all except for one man, known only as the emperor of mankind.
This man, a combined essence of mankind first warp touched, who had influenced and protected humanity behind the scenes since the time humans started practicing agriculture, had watched humanity ascend and descent many times, and now, at the near end of the eight century of the 30th Millennium, he finally decided that time of secrecy and subterfuge was over, what mankind needed after the millenniums of isolation due to warp storms that wrecked interstellar travel for more than 5 millennium's, destroying mankind first galactic empire, was a strong, central galactic power, created through the fires of his vision through a Great Crusade, so that mankind survival against the horrors of both the material universe and the warp would be ensured.
In order to accomplish this, to help him he created the primarchs, 20 genetically-engineered transhumans, intended to be the immortal and superhuman generals and proconsuls who would command the Emperor's Great Crusade to reunite the scattered human worlds beneath his leadership, the very sons of the Gran Emperor.
Yet this was not to be, as the malicious entities of the warp, the ruinous powers, known as the chaos gods attacked the emperor laboratories where the primarchs were gestated, spirited them away through the Warp across the galaxy. Despite that the great crusade was still launch and slowly but surely all but 2 of the emperor sons were found in less than 200 years, all while unifying human worlds across the galaxy, purging alien empires that used humans as nothing more than livestock and bringing enlightenment and prosperity to all conquered worlds through the vision of the emperor.
The rest itself is history, as before the emperor dream for humanity could be fulfilled, 9 of his sons betrayed him for the great enemy, chaos the very essence of the warp, in the event known as the Horus Heresy forever shattering the nascent imperium of man, crippling the emperor at its end, requiring his permanent interment in the golden throne for his and the imperium of man survival while destroying his vision of a galactic human power based on humanism, progress and atheism, forever to be replaced with stagnation, religious zealotry based on the emperor figure and repression forever. This tale is well known, but what happened to his missing sons? The ones never known to the imperium of man history.
That tale is unknown for everyone, from the emperor, to his very enemies the chaos gods, all believing them dead, either lost forever in the depths of warp, or simply dead in the cold vast space void or some forsaken planet with no capability to sustain life. Yet that is not the case for one of his missing sons, for him instead of landing on any planet inside the Milky Way galaxy, transited through the warp until his gestation capsule accidentally entered through one of the tunnels of the eldar webway and not just any tunnel, but an experimental one, designed for travelling to another galaxy, specifically what humans called the Andromeda galaxy.
At the end of this tunnel lay a solar system, with a planet very similar to humanity homeworld, populated by humans and surprisingly by creatures almost equal to those found in the ancient human religions, this last ones having been created by the eldar who created the very same tunnel that led to the Andromeda galaxy, by means of their incredibly advanced technology and mastery of the powers of the inmaterium, to create what they themselves will describe as minor deities and different breeds of new human species to serve this former ones, in a place where the inmaterium was far more stable, free from the taint of chaos.
Their reasoning's were partly due to their curiosity on seeing how would humans that had been regressed technologically to Neolithic levels would interact and evolve alongside the most important gods in human mythology before they started to expand towards space, alongside the creatures associated with them, but most importantly their desire for new types of entertainment for their species who had grown bore and restless.
Unfortunately before the project was completed the fall of the Aeldari race happened, whipping out their entire galactic empire within seconds, by the actions of the birth of the chaos god of pleasure, excess and pain Slaanesh, dooming their species while also damaging many minor paths of the webway, including the one that lead to the Andromeda galaxy.
In this wrecked tunnel entered the gestation capsule of the emperors son, in a voyage that have him been conscious would have lasted to him at its most half a minute, but in realspace lasted several millennia, until finally exited close to the planet orbit and was quickly caught by the Terran like planet gravity and pulled towards it, descending as an incandescent star, forever changing the destiny of its inhabitants.
Japan, Mie Prefecture, Ise Grand Shrine, November 17 of 2007, 8:20 P.M.
Gorou Hyoudou leaned beside his car, parked outside of the grand Ise shrine, waiting patiently for his wife to finish her last prayers for their greatest desire, to be able to have a children.
While waiting he remembered with a bit of bitterness how much he and his wife had desire a children and their excitement the first time she got pregnant. Their dreams shattered when she had a miscarriage at the third month of pregnancy due to some negate reaction she had to some new kind of headache pills in the market that caused abortion in women's, after that they decided to wait for a couple of years before trying again, despite their immense desire for a little child to raise.
The second time she got pregnant she made sure to be extra careful and not consume any medicament that could affect the child, everything was looking up until the six month, when one morning she woke with a trail of blood in their bed, they rushed to the nearest hospital as quickly as possible, but it was in vain, they could not save the child, apparently something had gone wrong as Mikki body somehow started attacking the fetus, in the afterwards she got violently ill, and ended up coming regularly up to the hospital every month for the next 6 years before being cleared up.
The worst news happened when the doctors told her that a third pregnancy would extremely harmful to her health. That enough devastated her, and push her to search for any method that would allow her to had children, and after they exhausted all alternative modern medicine could provide, after 4 long years, they started trying the spiritual route with no success.
Gorou simply sighed as he took another cigarette, they had been tried for over 10 years now, already in their late 30 both and it didn't seem like they could actually conceive a child. He was taken out of his thoughts by the arrival of his wife, signaling time to go, as he starts up the car.
3 hours later, in road to Shima
Driving in the middle of the night in a dark road wasn't really something overly difficult for gorou, it wasn't easy but not overly difficult either, he simply was going at a slow pace.
"You know gouru, I must say I'm definitely the luckiest women in the world" his wife suddenly said in a low tone
"Really, why?"
"Because I have you" she said with a depressed smile
"Well if that's the case, so I am, after all a have you as my beautiful and attentive wife"
"You consider luck having some useless women" she said in a depressed tone
"Hey wait second you're not useless" he tried to reassure her
"Then how would you call a women who's seems only capable of killing her own children rather than birthing them"
"Honey don't say that! It's just been bad luck, we only need to keep trying and would eventually get one"
"Trying?" She responded bitterly "with have been trying for what? 15 years, I just don't think I can have one, and…and…. I always dreamed of been a mother, of caring a spoiling a little baby, raising him, and…and…" She started crying in sobs while her husband stopped the car and parked it at the side of the road to comfort her.
"Mikki, look at me and listen, when I've married you 12 years ago, an in all this time you have been the absolute greatest women that I could had ever asked for, you were always there for me, even after I failed in most of my life projects goals, from having my own company, to even earning a promotion in the same company I worked for almost 10 years, yet you keep been there for me" putting his hands on her shoulders "you're the absolute best wife anybody could ever ask, so please don't think about yourself like that"
After those words she calmed down bit by bit and after a large sigh she gave her husband a bright smile "thank you gouru, you always known what to say, I'm fine now, but you know I always wanted a child to raise, give it as much love as possible, spoil him or her, watch it grown and all that"
"It's okay, you known that no matter what I'm always here to support you"
"Well dear, I've been thinking"
"Of what my dearest sugary queen?"
"About, hey! Don't call like that, its, it's embarrassing" she responded, with a very flustered look in her face "why do I keep up to you, I really wonder sometimes?"
"Because you're the one true love of my life and so I'm to you"
"In that you're absolutely right" she gave him a bright smile
"So what was that you wanted to tell me?"
"Well, if we can have a child by natural means, why not adopt one"
"Perhaps? I never really gave it a thought to be honest. What brought that up anyway?"
"It was when I was praying at the shrine and I thought that well…Is just that soon I'm goanna start to grow too old for a pregnancy dear and I really want to raise a kid, so maybe… what do you think?"
"Well it really isn't a bad a idea, there's plenty of kids out there that need a loving parent and unfortunately don't have one and I really would be glad to fill that role" he answered with a smile
"So you support it"
"For you my beautiful sugary queen, I'll do anything to make happy"
"Oh please stop it"
"Why, you always love it that nickname" he smiled mischievously
"It's still embarrassing" she replied in lower voice with a noticeable blush in her face "but once we return to shima we'll start looking for the adoption, you promise"
"Understood, now let's get back to the road it's still a couple of hours before we get to shima and..."
At that moment, they both heard a massive impact, followed by the sound of trees been knocked down hard for at least half a minute until, coming out of nowhere they saw something literally making the trees beside the road collapse hard, followed by some sort of giant ball of flaming rock that slammed the road ahead of the car and continue rolling for over a couple hundred meters deep in the forest until it stopped.
The couple stood motionless and in complete silence for a couple of minutes, looking at each other until they decided to get close to the giant… thing.
"Mikki stay behind" said gorou sternly while walking towards the strange object, once it he got closer he could discern what it was better.
Rather than some meteor as he first saw it, illuminated by the pieces of trees set aflame it looked more like some sort of giant black cylinder, maybe 2 meters longs and 1 meter width, with the inscription II in the center of it. That caught his attention and against his better judgment went closer towards the object until he was a couple of feet in front of him.
Once he got close enough the cylinder seemed to burst in cloud of vapor that forced gouru to step back, once the vapor stop it, the strange object seemed to just open like some sort of capsule and dropped a lot of liquid. After it something seemed too got out with the liquid too, gorou panicked thinking that some sort of horrible alien would come and attack him and his wife.
However once he got a clear view, instead of some sort of alien monster what came out looked like a human child, a child no older than 5 at most, with short brown hair, light brown eyes, completely naked and covered in the strange liquid trying to stand up.
For almost a minute both the adult and children looked at each other in the eyes, while gorou was nervous, the child was unnaturally calm, like he was analyzing him, to see if he was a danger or not, until a heavy and cold breeze came and the child immediately shuddered and slipped onto the pavement.
This took him out of his stupor as he went to the child to see if he was okay, with his wife coming along almost immediately.
"Oh my god, are you okay kid?" he asked him, while his wife helped him stand up, she meanwhile took off her jacket to dry the kid and cover him against the cold weather.
1 hour later, outskirts of shima
After taking the child with them they discussed what to do with him, they didn't really know anything about him, where he came? Who his family was? Was he really human, or some sort of shapeshifting alien? In the end they decided to head to city police station to report him as a missing child they found in the woods, hoping that somehow the situation would resolve itself.
Japan, Shiga Prefecture, Kuoh city May 22 of 2008, 11, 30 P.M.
As time passed through the police launched a case of abandoned child and put poster with his image through the entirety of the Mie Prefecture, to see if someone could identify the little kid, while placing him in the local orphanage. First they tried questioning the child, but it bore no results as when the child started speaking, claimed to only remember darkness and before the couple that took him to the city. The Hyoudous decided to simply tell them that they found him alongside the road, omitting the part of space-capsule.
After 1 month they called up the search as it became clear that no one seemed to claim the child while orphanage decided to put in adoption once the police closed up the case, around that time the Hyoudous started to pay weekly visits to the orphanage to check on the mysterious child and when it became clear that the kid didn't seem to have any relatives and was putted in adoption they adopted him and named him Issei, meaning honestly for they believed that the Shinto gods had finally answered they honest prayers for a child, even if was in a unexpected way.
As time passed, the family ended up moving to kuoh, as part of job transfer assigned to gorou and despite been overall happy, they also started discovering some strange anomalies with issei, first was that he grow fast, really fast as he looked like a tall 10 year old despite been legally 6, the second was that despite growing up so fast he rarely seemed hungry, in fact he ate much less than either gorou or mikki, added to the fact that he was way stronger than he appeared at first glance, easily lifting things that even gorou would struggle lifting.
The third fact was that he was a literal genius, as he had already mastered hiragana and kanji script in less than a month, spoke a descent English, along with French, German and bits of Chinese by 3 months and could solve trigonometry algebra problems with ease at 4 months after they adopted him, it got to the point that they decided to homeschool him as they didn't want to put him in highschool yet with him been so young.
As in now the whole family was in the in the house of Touji Shidou, a friend of gorou who invited them to his house to welcome the family to the city and meet their kid, needlessly to say he was a bit dumbfounded by issei.
"So wait, he's really 6? He looks like ten going to eleven" say a mildly flasterbarget touji while eyeing the kid currently plying with his daughter
"Well that's legally issei age, he is the type to grow very quickly" said a mildly amused gorou "but don't worry I already consulted with the medics, they say it's no risk for his health, though he may it end a bit taller than most"
"You're sure? It just not normal"
"I know but the doctors already said that there's no danger to his health so no worries for now"
"Right. So congratulations on your kid, I'm sure he'll grow up to be a fine man"
"That my friend I don't doubt for a second, after all he already is looking like one" gorou responded with a grin as he watched issei and Irina play a game of tag.
"Come on Iri-chan you can catch if you put some effort" responded a happy issei while a frustrated irina started to pant.
"Stay…. Still ise-san"
"No can do" he responded with a grin while he sidestepped Irina who tried to tackle from behind while he was distracted "maybe if you weren't such a midget you could catch me"
"Hey I'm not a midget" responded with puffed cheeks Irina
"Well according to my dad were both 6, so if I'm this tall and you're so short that must mean that you're very, very small, hence you're a midget"
"I'm not small, you are just too tall" she pouted while raising her little arms in the air
"Well better be tall than a midget" responded issei with a bright smile that almost immediately banished at seeing his new friend depressed.
"Hey iri-chan don't be sad" he tried to reassure her "I just know the way to make super tall"
"Really" she said with a shy smile
"Yeah like this" immediately and faster than little Irina could process, issei put her on his shoulders "see, now you're even taller than me" say with a grin
"Yes! Look I'm Irina shidou the tallest girl in all japan" she exclaimed with an excited voice "Ise, eh"
"Yes iri-chan"
"Can I have a piggy ride?"
"Though you never ask" with that he started to run and jump around
"Look daddy I'm flying" exclaimed in a happy tone irina while waving her arms around
"Issei be careful and don't jump that much" said gorou, worry that irina might fall off
"Don't worry dad that im holding her still"
"Just don't jump that much"
"Okay"
And so that day a beautiful, albeit particular friendship was born between a little girl and a singular child among men, one that would create ripples among both the human world and the entirety of the supernatural that existed on their planet, having far-reaching consequence for the future, but as in now were two kids in the beginning stages of friendship. And thus at the end of the day both kids and their families became close friends, settling the bases for massive for world changing events in the future.
And done, well fellow readers and writers I hope you like it. The inspiration for this fanfic comes primarily from two sources. The first is Shepherd of Humanity by Empirialtank and the second is Prim-Arc by vixvix, both of them fantastic and ongoing fics that cross both the Warhammer 40k franchise Mass Effect and RWBY respectably perfectly, please read and follow them both there amazing.
Anyway I've seen plenty of crossovers detailing issei as son or descendant of a powerful being, so I wanted to try this concept that is of issei as a primarch, just for you to know there will be major cannon divergences as our young primarch walks through the world of dxd.
Don't worry I won't make him to OOC, issei will still be the pervert (through lessened by a reasonable degree), nice and heroic character that he is in canon, but he certainly won't be as naïve as originally in the series and while also be more prone to resolve confrontations with violence.
Also don't expect much of the Warhammer 40k stuff to show up soon, there is a massive void and 2,537 million light years between terra and the Andromeda galaxy and the webway tunnel that leads there is pretty wrecked so nobody from his home galaxy is coming anytime soon.
