Within DxD, as Set sitri

Darkness.

True endless darkness.

That is all he could see, the moment he reopened his eyes after going through that hell.

The hell of dancing flames.

The hell of the black smoke, that entered his body, making it harder and harder for him to breath.

The hell of heat from those very flames, that messed with his mind, and his judgement, when he went through that hell together with his twin younger brother, who he carried on his back.

He still can remember the sounds of people crying and screaming, while the flames took their loved ones.

Or the sounds of those that betrayed others, so they could selfishly save themselves, before the storm of flames get them as well.

Also the crying child, that lost all hope, when she saw her mother being burn alive before her veery eyes.

The man remembered it all, as he carried his young brother who lost everything on his back. And grabbed that girl who lost her mother, forcedly by hand.

He didn't once think, if it was right, to forcedly dragged that girl in that hellish situation, or it was the right judgement at that time. After all, at that time, in those hellish flames, due to the heat itself, he cannot think right.

One might think he is a hero, saving that girl, along with his twin brother.

But the man himself knew himself better. He knew he is no saint, nor he is a hero. He is just someone who knew, if he were to leave that child to those flames, he will regret it.

Not to mention, maybe the bigger reason why he dragged that little girl out of that hell, maybe due to sole fact, that he and his twin brother knew very well, what it feels like to have your own mother died before your very eyes.

Which is properly why he took the risk, and forcedly took the unmoving little girl with him by force.

When he and his twin brother lost their mother. Was also the day when everything changed to the brothers. It became the day when his twin brother lost the ability to walk.

And also the day when he too, had no choice but to quit college, so he could support his only family he has left, by doing multiple part-time jobs or jigs at once.

It's not like the brothers have no other family left. They still have that so-called father left.

However, that man had left them, his mother and themselves for another woman a long time ago.

So one could say the twins want nothing to do with that person, who was willing to let a woman raise two children alone. Which is also why, he, the oldest among the twins, helped each way possible.

Be it cleaning, cooking, he did it all for his family.

If it wasn't for his mother and twin brother being forceful with their words. He wouldn't even attend college, since he only attended and went for their sake.

However, as we all know, life is a bitch.

Even if you walk one way, life will bite you another way. That is how life is seen in the eyes of the older twin brother, who looked after his brother, whose life became full of despair.

And in the abyss known as despair, his twin younger brother found a hobby that helped him in this despair. That hobby was called anime, or what he likes to call it anime culture.

Honestly, he doesn't know the difference. Nor he has the time know about it, since he always working, or dealing with something else.

Due to him being always busy with something, only made the distance between brothers longer and longer, to the point they no longer twin brothers, but strangers to each other.

And that remain the same until that day, the very day when that flaming hell came before them.

In the end, he managed to drag the little girl out of the burning apartment building they lived in, that is now in flames. While carrying his disabled brother on his back.

However, due to breathing in too much black smoke, he did not make it.

The last thing the older twin brother remembered. Was being rushed to hospital. But that was it, since he died on the way to the hospital itself.

And the next thing he knew, the moment he died, was the moment he came to this dark place before him.

There is nothing here, nothing he could see, nor he could move a finger here. No matter how many times he tried to break free whatever holding him back, nothing would work.

But over time, things begin to turned strange, and then even stranger.

At first, he discovered he could move a little, but that just it. Even moving a finger took a long time, and a lot of energy, before he could move his arms and legs. But even if he could move them, he cannot move anywhere, as if something is chaining him in this darkness.

But as some time passed, the moment he could somewhat move his body some more. Was the moment when he discovered he wasn't alone in this darkness.

He already lost count, how many times something besides him hit or touch him. Or the times when he hit or touch them as well when he tried to move within this darkness.

Of course, this wasn't the strangest thing. The strangest things came the moment he capable to hear voices beyond the darkness itself.

'Oh… is… my babies…?'

At first, the voice was hard to tell, or what they were saying.

But he could somehow hear them and understand them for some reason. He could understand what they are saying, and this made the man trapped in here suspicious, that he could understand their words, like it was his own language.

And it was than he realised his own situation.

He wasn't in the abyss.

He wasn't in the void, after dying to save his brother and that little girl.

No, he was reborn.

And for some reason he could remember who he is inside his new mother's womb.

The man, no, now unborn baby, didn't know how he should take this situation. After all, he is no otaku or anime nerd, who has no clue what isekai is, even if he has heard that term least dozen or so time from his former twin brother's mouth.

Instead, he does he always has done, he didn't mind the situation, even if he has complicated emotions about the whole damn thing. And decided to go with the flow.

Little did the unborn baby knew, soon he will begin to question the sanity of his mother, and the other people beyond his mother's womb.

'Fufufu, my little Devils are lively today.'

That was the first time he clearly heard his new mother's voice. Which didn't alarm him at that time. But it also did confirm he wasn't alone, and it wasn't inside his head that someone keep kicking his ass from time and time again.

'Ahh! I feel them move mother! They are kicking!'

'Serafall calmed down, will you?'

'Hahaha, sorry, but I am going to have a little sisters or brothers? Or maybe a little brother and sister? I can't wait! I already got their costumes ready! I can't wait to see them~!'

'Serafall, I told you to calmed down!'

'S-Sorry… I might get a little carried away~'

'As long you understand… they can hear you just fine, why not speak to them, I am sure, they want to hear their big sister's voice.'

'Good idea!!'

'Serafall.'

'I mean… a good idea. Ahem, this is your big sister guys, I promise I will treasure you both, and on my title as the Great Satan of Leviathan, I will not only made sure to protect you, but no one would harm you either, after all, you two are…'

When he heard this, he learned for the first time, he has another sister, besides the one kicking him. But strangely enough he swears he heard something off, but before he could hear the rest of her words, he fallen asleep once again.

'My children, my little girl and boy, hahaha, you have done well, Zlata, my, no, our little Devils, by Satan I am thankful for my two new children, and I hope they grow into wonderful Devils.'

'I am sure they be fine; they are your children after all. Knowing your genes, they might even like chess a little more than their own wife.'

'Th-That is not true, it is true I want to show my little ones, the joy of the game known as chess, that similar to the Evil Pieces, but that's not it! I swear on the Original Satans' names, I don't love chess more than you!'

'I know~ I was only joking~ But, I do hope our children grow happy in this world our oldest fought so hard to create… Speaking of Serafall, have you heard, she already got their costumes ready to match her new show. Shame, she wouldn't be able to make it back to see their births, she was looking so forward to them being born…'

'But that is the price for being one of the Four Great Satans. Don't worry about her, my dear wife, she is a strong child, no, woman.'

This was the first time when he heard his new father's voice. However, the stillborn baby, who still can remember his past life, became frozen upon hearing his new father's words.

Devil?

Sitri?

By Satan?

And Four Great Satans?

When he heard this, he cannot help to cursed his luck when realised, he is about to be reborn to become a child of satanists!

Out of all things, why does he have to become a child belonging to a fricking cult of all things!?

Realising how serious this situation truly has become, to be reborn to satanists of all things, the not born yet baby cannot help but to curse all of his luck that never existed, and even thought of ways to escape when the moment he is capable of doing so.

Of course, there is one thing that did made him slightly curious.

And that is… why is it called Four Great Satans? Isn't there supposed to be one Devil only? When did the other three Devils from?

Nonetheless, he has very little, he means very little interest finding out who the other three are.

Not to mention, he is not looking forward to being brainwashed, so in the darkness of his satanist new mother, he planned his escape, of course, he going to take the brat that has been kicking his ass cheeks all this time

There is no way he going to let his twin sister (So he hopes he's the boy they mention) in the hands of those monsters!

After all, in his first life, he had read what cultists or even satanists do to their own children that has been born in their cults.

Some are sacrificed in their sickening rituals. And make things worse, the girls are groomed to be raped when they come to age, or worse yet while still a child.

So they no freaking way he will let his twin sister face such a fate, that why, still cursing at his luck, to be born to satanists of all things.

Little did the unborn baby knew, how wrong he really is…

(A/N: Imagine you never read or watch anime, and you throw in the world of Devils? How will you react?)

…

..

.

In the tall towering castle known as the Sitri Castle, where the main bloodline of the House of Sitri live. Lies two young black haired babies laying on their backs in their crib/cot.

One of black haired babies that only a month old, played with some soft toy, as she cutely bites it. Her violet purple eyes locked onto the toy before her, as she tried to ripped it apart, shame she is lacking the strength to do so.

And while the girl of the two playing with her toy. The boy of the two twins, looked at the ceiling with a deadpan expression.

'This damned body…'

Thought the baby boy known as Set Sitri, as he hatred the fact, he cannot move properly, as he felt he could barely has any control over his own body.

It been a month since he is born into this strange world.

Yes, strange world.

First thing first, besides the fact, that everyone is a little too good looking, or why women have breasts, that seems too unnaturally big, like they wanted to free themselves from their clothing.

The thing that caught Set attention at the moment his violet eyes could see clearer.

Was the freaking sky being purple of all things.

Not to mention, everyone here has these vampire-like wings.

However, from the understanding from his new mother, or the maids that take care of him. They are called Devil wings, since sometimes the maids will show them to him and his sister.

While his sister grabbed held of them in a playful manner. The boy in question, gives the confused maid the dead eye, becoming wary of these satanists…

Of course, soon the boy learned these people are no satanists. No, they are in fact the very beings that satanists have wet dreams for.

Yes, they are Devils, the real thing. He doesn't get why they are called Devils, or why they looked more humans, besides their bat-like vampire wings.

But the thing that Set Sitri knew, he has become a Devil. This made him question, if he should cancel his running away from the freaking satanists plan or not. Since he is now a Devil of all things.

'So is this hell? No, more like another world. If this is hell, what kind of sins did I do in my past life, to become a Devil? Not to be sent to hell, but to become part of it?'

Set examines all the little pieces of information he has on this new world he been sent to.

Another thing that also solidified his reasoning this is a new world, is because of Magic exists in this world.

He saw the maids' casts simple spells to cool down the room, or warm it up. Or how they clean the room with those spells. For someone who cooks and cleans a lot in his past life. The first thing he wants, are those spells.

You have no clue how tiring cleaning is sometimes, and seeing them do something, that takes ten minutes, to be done in a less than a second. Only burn his desires to learn those damned spells!

Of course, when he thought why he wanted those spells. He recalled his past life. He recalled his first mother, that deadbeat father, and his twin younger brother, who lost everything.

Some might say, with his disability, leaving him in that fire, might save his own life. And they are right, if he did leave his twin little brother of his past life behind, without a doubt he wouldn't be here, and still alive in his past life world.

But if he has to go through that living flaming hell again, to save his twin younger brother, he will do it again, without thinking at all.

After all, family is family. No matter how useless they are seen in the eyes of society.

Besides thinking, or doubting everything, or learning.

There nothing that Set Sitri could do, besides sometimes being kicked by his twin sister, Sona, who still playing with that soft toy, that looked like some kind of sea dragon?

'Is there Dragons in this world?'

Even if the man never seen anime, or manga. He still likes some fantasy elements, one of them are Dragons. And if they are Dragons in this world, he will love to see one.

And yet again, the realistic part of his mind kicked in. What are the relationships between his race, the Devils, and the Dragons?

Are Dragons like lone wolves, as he imagines? Or they part of some group?

And they are natural to the Devil Race? Which he doubts, after all, they are Devils of all things.

While the month old baby having such meaningless thoughts. All of the sudden a change in the air changed, as he felt something he felt many times, when the maids used those spells, the source of mana…? No, mana doesn't suit Devils… Demonic Mana? Or maybe Demonic Power?

As he thought of that, a magic circle appeared in the room of his and his twin sister. And like that, a flash appeared, only for a strange looking teenager to appear.

"Ta-Ta! Your favourited magical girl is here! Levia-tan☆!"

Went the strange looking teenager, who given Set a nagging feeling he heard this voice before.

However, at this moment, it didn't matter why this voice sound so familiar. Instead, Set looked at the strange looking girl, or magical girl so she says.

And knew right away, this girl, she is either a crazy teenager that lost her mind, and for some reason ended up in this room of all places.

Or what Set think she really is… she is a kidnapper, isn't she?

Set took a closer look at the beautiful girl who looked in her late teen.

She has long black hair that tied in a twintail, that gives her a young and childish vibe to her.

As for her body, it unknown if she in her late teens, or she just shorter compared to the average height, but her big breasts do standout due to her short or youthful height.

However, it not the breasts or her youthfulness that got Set's attention, after all, Set actually lacks the hormones to care about those round things.

What got his attention… is her strange attire, that is like a dress? And the wand in her hands… do Devils need wands??

Set knew she is a Devil, due to having the same kind of energy he could feel from the other maids, and his mother and father has inside them.

'No… that is not important right now…' Set thought, as his violet purple eyes turned serious, and looked at the strange teenager, who seemed not to noticed the serious looking baby looking at her.

Instead, she looked at the baby closest to her, who also seems to be looking at this twintail beauty if she her new toy, as she went on her all fours to go towards her.

"Oh mine~ You happy to see big-!?"

The moment Set saw this stranger reaching out to his twin sister, Sona Sitri.

His mind became blank.

Flames of that day resurfaced inside his mind, even if it has been some time since the day of his death.

Those flames never left his mind. Neither did the countless cries of those either dying in the flames, or those who betrayed others also died in those wild devouring flames.

Within the short time he has been with his older twin sister, Sona. Either it was still in the womb or out of the womb.

Sona Sitri has become a somewhat important existence to Set.

Maybe as a replacement to his young twin brother in his past life.

Or maybe it was something else altogether.

It didn't matter to the current Set the reason why.

What does matter, the moment when he saw this stranger reaching out for his twin sister, the flames, his brother of his past life, and even Sona all overlapped inside his mind.

And just like that, the very same source of power that this twin tail teenager, the maids, and even his parents all have, begin to awakened inside Set against his own will.

The thing that Set Sitri yet to knew, that is called Demonic Power began to give a powerful aura, that even the teenager girl, out of reflex entered a deadly serious expression, when she sensed the Demonic Power before her.

The strange looking twintail beauty also noticed this increasing Demonic Power, that could rival that of a Low-Class Devil.

And oddly enough, this Demonic Power, seems to be increasing by the moment? The twintail stranger eyes narrowed, as she suddenly become deadly serious, like she could even kill a God, how mad she seems to become, when she senses this energy.

However, her rage, her resentment faded like the wind, when she noticed who this Demonic Power coming from, were no other than Set himself, the other twin in this room.

The moment when the strange teenager saw Set, two types of emotions could see in her clear blue eyes.

One is pure disbelief, that a one month baby has Demonic Power reserves that rivals the average Low-Class Devil, not to mention the Demonic Power is still raising.

And the second emotions that could be seen in those blue eyes?

Were extreme concern and fear.

After all, there never been in the whole of the history of the Devil Race, a Devil who only a month old, has Demonic Power reverses that rivals a Low-Class Devil, and that worried this twintail devil for many different reasons.

…

..

.

Time before Set Sitri was even born.

Within the real void, lies two beings. One is a young man who has no working legs, and yet this young man stood within the void, while facing the being who made of pure white flames.

{You are the first one before me, who wished for something like this. Who will guess you will use your own first wish for someone else? How interesting, is this out of selfless I wonder? Or is it guilt? When you wished for your own brother to take your place in this second chance at life, I gave you?}

Went the flaming being, whose powers are beyond the levels of Gods and Divine beings themselves.

"Who knows? However, if you are truly a ROB, not only you can read minds, but you should know, what kind of crap that brother of mine went through for me and our dead mother? Not to mention, he has no idea, does he? That I died while being carried on his back."

Went the man with a bitter smile, stating a truth that his brother will never know.

{That is true, only one that made it out alive of you three, was that little girl. Now then, tell me what about your second wish?} Asked the flaming being made of white flames.

"Simple, I wish my brother has unlimited potential, and make him into a Devil, and he has to be part of the Sitri Clan, and related to Sona Sitri, along with the knowledge how to use that Water bloodline ability of his to it's true potential. I always think their way of using their Water ability is weak. I mean, if you think about it, is Serafall's Ice ability is really mutation of their Water, or is it just Water, that frozen?"

Went the legless man, who stood before the flaming being.

{Interesting, you are right, the one known as Serafall and the Sitri, in the end their ability of Water is the same, it just it has manifested into Ice due to her trauma during the Devil Civil War, that changed it into Ice, but if she really looks into, it is possible to switch between Ice and Water, fine I allow it, the second wish is allowed. But tell me, why Sitri, or more like why he has to be related to the House of Sitri? Wouldn't the House of Gremory be better?}

Went the flaming being, who already knew why, but he wanted to hear it from the man before him. And the man in question grinned hearing the ROB's words.

"Two reasons actually."

{Ooh, and they be?}

"First, fanfics with Sona being a love interest is overused, like Momo in MHA. And I know my brother, wouldn't be into incest and all that shit."

{And the second?}

"Simple, Serafall is my waifu, I wouldn't let anyone have her. Not even my brother… it's simple as that."

When the man said that the white flaming being, could sense the obsession within his eyes. But in the end, the being that beyond God, didn't care the reason behind the obsession, or more like he or it already knew what it is.

{Hahaha, fine, I expected as much. What about your last wish than? What is the last wish of yours

When the flaming being asked this. The young man, who looked in his late 20s, looked at the void, as a smile appeared on his face.

"Simple, as a NEET, I would live the rest of my life as one. I want to watch his life, his actions, like I am watching a TV show. By the way, I am not into seeing my brother taking a shit, or when he fucks someone, so please cut those screens out. It will be damned weird if you don't. That is my third life, I always referred to be an observer, than being involved into something."

When the man said that the flames being didn't say anything, but instead, he snapped his fingers, and when he did, a flat Tv show up, along with a chair, and other things like snacks.

{Just think what you want, it will appear, be it snacks, anime, video games, anything. Do note, if something related to the canon appeared, or something important to your older brother, the Tv switch to your brother no matter what, this means, even if you are playing some game, watching anime, or jerking off to some porn, it will show your brother.

Of course, as requested, I will blur out any forms of sexual content, nudity, or even when doing their business. Now since I have given you your three wishes, I will show myself once in a while, until then, I hope you wouldn't regret your choice, of being an observer.}

As soon the being made of white flames said that he vanished without a trance, leaving behind the young man with shattered legs.

"Wait… besides the business thing, and the sexual content thing… what you meant by nudity? You want me to watch DxD, live or not, with censorship!? What kind of monster you are!?"

The young twin brother laughed aloud bitterly, before he turned to flat Tv, when he did, the Tv automatically turned itself on. And when it did, it shows two babies on the screen, one is a girl, Sona Sitri, and the other is Set Sitri.

The man with the battered legs, looked amused, when he looked at the deadpan expression on the male Devil newborn baby's face.

"Like it mattered if it censored or not. In the end, a true NEET, is a true NEET, that is who I am, you would agree as well? Big brother."

Went the man left alone in the void, as he lazily sat down on the very comfortable chair, that comes with a leg rest. And simply summoned a glass of wine, before he raised it towards the wary looking baby, who watching his surroundings, if everyone is an enemy.

"I don't know if this counts… but count this as my payment what you had done for us, brother." Went the man, as he first hand watched the fate of his twin brother's life in a world, he knows nothing about.
