Chapter 7: Code 001

Somewhere hidden in Japan. —

In a well-decorated white office, you could see a handsome adult with blond hair and violet eyes, the man was wearing clean clothes of a light color and over his clothes a large white doctor's coat, sitting in his armchair looking at the papers that were on the metal table.

It was reports from an experiment subject who belonged to the hidden installation of the human eye.

In the reports, the following data related to the subject of the experiment could be seen.

Report 1: Prenatal Phase

Title: "Origins of Power: Nanomachine Experiment on the Fetus Code 001"

Background: During the fetal development of 「Code 001」, it was subjected to a revolutionary nanomachine experiment. These nanomachines were introduced into their biological system from an early stage, resulting in exceptionally rapid and strengthened growth and development.

Fetal Development: The nanomachines infiltrated 「Code 001」 cells and began to reinforce their DNA and tissues, accelerating their development and protecting them against any potential threats during gestation. This resulted in an exceptionally healthy and robust baby at birth.

Impact on Later Abilities: Although superhuman abilities did not yet manifest in the prenatal phase, nanomachines laid the foundation for their future growth. His body was infused with nanomachines, ready to activate and enhance his abilities for years to come.

Report 2: Early Childhood (Newborn to 5 years)

Title: "The Prodigy's First Steps: Code 001from Baby to Child"

Development & Growth:

From its birth, 「Code 001」 grew and developed at an astonishing rate. His muscles quickly strengthened, allowing him to perform physical feats that amazed those around him. Within a few months of life, he was able to walk and speak fluently.

Intellectual Skills:

In addition to his physical abilities, 「Code 001」 demonstrated extraordinary intelligence from an early age. He had an astonishing ability to learn and a photographic memory that allowed him to recall details with astonishing accuracy. His brain became a formidable tool for understanding and solving the challenges that came his way.

Discovery of Physical Abilities:

As he grew older, it became apparent that 「Code 001」 possessed extraordinary strength. He was capable of astonishing physical feats, such as lifting objects of enormous proportions and destroying structures with ease. He also demonstrated impressive speed and agility.

Observation:

Despite his ability to perform impressive feats, nothing assigned to him provided the intellectual and emotional challenge he craved. This observation led him to question his purpose in life, seeking out truly interesting challenges.

Report 3: Middle Childhood (5 to 10 years)

Title: "The Awakening of Talents: Code 001in its Middle Stage"

Special Skills Development:

During this stage of his life, 「Code 001」's physical abilities continued to expand and diversify. He developed the ability to increase his strength to even more impressive levels, allowing him to perform feats of large-scale destruction.

Intellectual Skills:

His outstanding intelligence became a valuable tool for solving the mysteries surrounding his life and for understanding and strategizing in challenging situations.

Training & Control:

As he approached the age of 10, 「Code 001」 began to train and hone his physical and cognitive skills, learning to control his strength and agility accurately. Its speed and endurance also increased, approaching the speed of light and the ability to withstand devastating impacts.

Observation:

Despite his extraordinary abilities, his morality propelled him to seek a deeper, more meaningful purpose in his life, even if it meant facing life-threatening situations and using his intelligence to solve intriguing challenges.

Report 4: Preadolescence (11 to 13 years)

Title: "Awakening of the Defiant Code 001(11-13 years)"

Physical and Mental Development:

During these crucial years, 「Code 001」 continued its exceptional development due to the influence of nanomachines. Her body began to show the transition into adolescence, revealing a more developed figure. Although the specific characteristics of nanomachines remained a mystery, their impact on 「Code 001」's physical abilities was undeniable.

As her physical appearance shifted towards that of a developing young woman, her intellect grew at an astonishing rate. He developed advanced cognitive skills, displaying exceptional memory and an ability to comprehend complex concepts with ease. Her keen intelligence made her stand out even among the most educated adults.

Installation Challenges:

During these years, 「Code 001」 continued to face challenges designed to test his skills. Despite his more mature appearance, his boredom began to manifest itself clearly. Although the challenges were becoming more complex and dangerous, 「Code 001」 expressed growing dissatisfaction, indicating a search for more meaningful and exciting stimuli.

His relationship with researchers and staff at the facility showed signs of strain as he expressed his displeasure with the lack of truly exciting challenges. Observations indicate that despite his apparent obedience, 「Code 001」 craved something beyond the limits set by the facility.

End of Reports.

Finishing last going through the written reports with the years of observation to 「Code 001」, there was a serious problem with it.

It was very obvious that his dissatisfaction and boredom is a ticking time bomb.

At any moment she can disobey orders to continue investigating or even worse... kill them for mere entertainment.

Sigh. —It's getting worse and worse... There's no way to stop it now... We've focused too much on the nanomachine particles in your body, that I never try to create a contingency plan so you can follow my orders. Even if I were to fight her, it's very obvious that I'll lose... I need the help of a divine entity to help me control it...

He began to get up from his chair and then walked to the door and out of his room.

"For now, I must move quickly in expanding this experiment into more genetic profiles. Maybe she will find another subject who is easier to control and will be the right one to stop her, she is still evolving, we don't know what the limit of nanomachine particles is in the human body, but it is definite that this is the evolution of the human to a second generation."

He continued his walk to a room at the end of the hall while worrying about the future of his experiment.

The experiment facility was a vast and gloomy place, permeated with a cold, barren air. The gray metal walls stood imposing, dim lights casting a pale illumination over the endless corridors. Tubes and wires twisted across the walls and ceiling, connected to complex machines and devices whose function only scientists could comprehend.

The echo of footsteps echoed on the concrete floor, as 「Code 001」 walked through the deserted corridors. His gaze rose to the ceiling, where a series of frosted glass windows let in faint moonlight. Through them, he could catch a glimpse of the stars twinkling in the night. It was a constant reminder of the outside world that had been left behind.

「Code 001」 was an unusual-looking young woman. Her long, blonde hair fell in messy strands around her face, adding a touch of rebellion to her appearance. Her purple eyes, deep and almost hypnotic, stood out in contrast to her fair skin.

She wore a white straitjacket, which was often associated with psychiatric hospital patients, though in her case, it was more of a statement of her boredom and her desire to find something that would truly challenge her. The straitjacket, while unusual, gave him a sense of control over his own situation, as he could free himself from it whenever he wanted, but chose not to.

As he stared at the ceiling, he longed for something more, something that would challenge his mind and spirit. He craved the thrill of a genuine challenge, something that would make his heart pound. But in the facility, everything seemed designed to keep him contained, as if he were trapped in a gilded cage of extraordinary abilities.

The starlight on the ceiling seemed as distant as his dreams of liberation. 「Code 001」 He knew that there was something beyond those walls, something that awaited him in the outside world. And he was determined to find it, no matter what it cost him.

—The time has come for me to leave this place, if I keep waiting for what I want to come to me, it would be completely absurd. It's like shouting to the heavens that I want money only to never receive it when the truth is that I'm not even trying to get it. —I released my arms from the straitjacket, destroying it to free myself. —If I want a challenge that stimulates my spirit I must go for it, if there are gods, demons, monsters, or any interesting creature outside and that has the ability to give me a challenge that satisfies me, I will look for them and fight with them, continuing to be in this place will kill me of boredom.

I raised my fist as high as I could and then lowered it and caused a catastrophe by destroying the entire facility.

Maybe there is a survivor or maybe not, I didn't care about the truth.

Mhmm... I managed to feel the presence of someone a little away from where I am.

Oh, if someone survived, it's because they're not a normal human.

Interesting!

I went to the person who was "alive" to have an interesting confrontation for me.

» ━━━━━━ « » ━━━━━━ «

—Michael-nii-sama, that was it?

Asked a beautiful woman with blonde hair and emerald, green eyes where her voluptuous body wears a beautiful white silk dress, on her back you could see 12 wings of a white cigar.

She was surprised but curious to see her older brother Michael, who was a handsome man wearing a priestly white robe, having in front of them a divine artifact observing the catastrophe of a facility hidden from the human eye, but not for them, seeing how a young girl had destroyed that place without any apparent effort shown in her facial expressions at the moment of destruction.

Michael, feeling a little guilty, decided to give some information.

—She was used in an inhumane experiment... by his own father, and what you're seeing is the pinnacle of that experiment... I've been watching her all these years.

—But because you never saved her from that place! —pointing to the already destroyed facility.

Michael, without looking away, said seriously.

—You must know by now that we are forbidden to meddle in human affairs.

—You may be right, but why not try to save an innocent life by ourselves!

—There are many human lives that are in worse situations, she is one more of the bunch. —Michael said cruelly.

That thought will one day be our downfall! —For the first time his sister had shown a feeling of anger toward him.

He wanted to excuse himself, but something unexpected caught his attention.

—There's someone approaching that place.

She wanted to continue lecturing her brother, but what she said also caught her attention and she decided to look at what was happening on the human ground.

As it was night and a torrential rain had also begun, the person walking to the destroyed facility was hidden by a black umbrella that did not allow him to observe the profile of that person.

—Gabriel.

—Yes, Nii-sama?

—I have this worry that something big and dangerous is going to happen in the next few minutes.

—Gluh... I think the same Nii-sama... This can change the future of the world.

They began to look on with uncertainty as to what was going to happen because of the arrival of this mysterious person at the facility.

All they could do was pray for their dead father, so that what was going to happen would not be something serious and dangerous for everyone.

» ━━━━━━ « » ━━━━━━ «

—Wow, it's interesting to see him alive Dr. Touya, or should I call you 'father' even though it feels repulsive to call you that?

In front of her was the doctor who was reading the reports, but his clothes were not injured, they can't say the same since he was ragged.

—It would be weird for you to call me 'father' when I was the one who caused you to use yourself in the nanomachine experiment on you.

—Ha, you're right about that part. But let's stop chattering, seeing that you managed to survive this it's obvious that you're not a normal human.

—He's right, but I suppose you wouldn't let me go if I asked you.

—No, I'll come after you even if you escape.

Sigh. I suppose I have no choice but to fight you.

At the moment they were about to fight, a strong sense of danger invaded them.

Quickly looking at where it came from, they had different reactions.

The girl had a confused face of who this person who had arrived was.

But in contrast to the doctor, he had a feeling of disbelief.

—He had heard information that he was sealed 「Demon Lord」King Oni.

The mysterious person showed a smile of amusement that was picked up by them.

—You should remember how strong I am, a simple seal from that woman won't be enough to keep us imprisoned forever.

The girl wanted to find out who she meant by "us", something the doctor understood, showing a face pale with fear.

—So, you and also your friend escaped the seal that you were chained until now that 200 years have passed.

He tore his neck as he continued to respond. —It was the most boring 200 years of my life; I hope several heroes were formed to finish us off.

—So, the reason for your coming here is to take 「Code 001」 with you and train her.

—It's the initial plan, but I also have to do something with you; But first I must ask you if you want to follow me.

He turned his gaze to 「Code 001」waiting for his reply.

—Seeing that you are strong and will train with you, I will follow you, but promise that I will have more fun.

—Hahahaha, you'll have to fight some gods as part of your training.

—That captures my interest, I can choose a specific group of gods.

He was motivated to fight.

—I chose, any pantheon will fall with your fists.

—Hahahaha, then I'll choose the Norse pantheon, of all the mythologies the Norse is my favorite!

He replied with a big wild smile.

—Mhmm... Someone else will also go to the Nordic pantheon, I hope you won't mind that.

She frowned. —He'll take the fun out of me if he intrudes on my fight with Thor and Odin.

—You don't have to worry about that, she'll just cause chaos. After all, I seek a full-scale war with all supernatural and divine beings.

—A full-scale war? Perhaps he intends to end the world. —The doctor spoke in amazement, listening to the whole conversation.

—I don't intend to end the world, but maybe this war will be extinction for the living beings that live in this world, it will be a shame for them if that happens.

—I don't care who lives or who dies, I want to satisfy my heart; Being locked up in this facility was boring me to death, so I'll go with you.

She started walking to get to his right side.

—Then it's decided, as I said, I had another plan with you, Dr. Touya. —She instantly appeared in front of him, holding her right hand to his head. —You have to go somewhere else and fulfill the destiny of someone else who is destined to become a 'hero'... And then he came to this place and fought with us. —he said the last in a whisper for the doctor to hear.

—Don't tell me, the experiment of the-

He had disappeared without a trace, without finishing what he was going to say.

From his pants pocket he pulled out a cigarette and lighter and then began to smoke.

I inhale a puff of the cigarette, then exhale the smoke. —It's time to go, as you wanted, we'll start your training by fighting with the Norse pantheon.

His eyes began to glow a deep red that showed obvious danger for what is going to happen in the future.

Underworld, House Gremory. —

I was walking to the kitchen; I would like to eat back the sweets called dango.

It became one of my favorite candies.

I hope Samuel-san has some dangos ready.

—Hey, is this place the way to the kitchen?

Someone had called me suddenly; I turned my head to see who it was.

I was surprised, as I didn't know who this person was, but he has the same shade of crimson hair as the Gremorys.

Her hair was loose past her waist. And his clothes were too wrinkled, as if he had just risen from a long sleep.

—If it's the way to the kitchen... But who are you? —I said with cordiality and respect for that person.

—You look a bit like Zeoticus-chan when I last saw him when he was a child, and for your question my name is Runeas Gremory, progenitor of the [Gremory]. So, I'm your ancestor... What's your name?

—Mikoto Gremory, the new heir to his prestigious family.

I bowed my posture of reverence.

—So, the new heir... how many centuries have passed... the last heir I met was Zeoticus-chan… —I heard her speak as her voice lowered in volume. —Well, it doesn't matter, let's go to the kitchen, I've been sleeping for a long, long, long time; So, I want to eat something!

His personality change took a 180° turn.

I just nodded to his request.

We walked to the kitchen while we talked about some things that weren't of much importance.

Clac

We opened the kitchen door, and I recognized some cooks as well as the [Queen] of Rias.

—Mhmm, what are you doing here Akeno-san?

—Hello, Mikoto-sama, and who's the oldest?

—Ancestor Gremory.

—It's the first time I've met you, Ancestor Gremory-sama.

He bowed respectfully to my ancestor.

—Call me Runeas, so it belongs in the kitchen, aren't you too young to be in this sector?!

—She's my sister Rias's [Queen], she must have come to prepare something for her.

I replied monotonously.

—That's right, I've come to brew black coffee, it's the first time Rias-sama wants to drink something bitter.

—You're right about that, she'd probably drink something sweet to her palate.

I was meditating, maybe that fight is starting to change in many things for Rias... But I guess it's okay, he's growing up to be a better person.

—Oohh, I'd like to meet your sister Mikoto-chan.

—Mikoto-chan? —I felt a shudder of disgust in my body. —I'd like you to just call me Mikoto without honorifics, please.

—Ara~. Because, yes, Mikoto-chan is a nice name. —returning that feeling of displeasure, I observed how Akeno-san hid her mouth with one hand; He seemed to be having fun. —Mikoto-chan, you'd like me to help you prepare something to eat.

—No, I'd rather eat later; I've got things to do so I'm leaving.

—Didn't you come to eat something, Mikoto-chan?

—Maybe later, Runeas-sama.

Please stop calling me Mikoto-chan, I'm shaking with disgust all over my body!

—Ara~ Ara~, I suppose there's no other way if Mikoto-chan wants to eat later.

She's probably having fun.

For now, I'm leaving quickly, I'm sure Akeno-san will keep calling me that.

—By the way, Mikoto-sama, Zeoticus-sama wanted to talk to you, he gave me that message in case I saw you.

—Huh... Akeno-san understood.

—I'll see if I look for Zeoticus-chan later, it will be fun to annoy him like those days!

It was the last thing I heard from Runeas before I left the kitchen.

My father said that I invite the other people I made friends to the meeting for tomorrow, which is my birthday along with Rias's.

"The cattle are gathered to you."

Sengo said with amusement.

"I have to make the list of who can win, I don't see Ravel as your romantic interest, but he will still be on the list. So, let's see: Sona Sitri (doubtful), Ravel Phenex, Seekvaira Agares, Latia Astaroth, Iryuka Glasya-Labolas; So that's five women... should I include your sister? With her it would be six."

Why the hell would I see my sister as a romantic interest.

"No idea, maybe because they're demons and breakfast is taboo for them."

Don't make me laugh, humans have also committed incest, so no species is spared from that taboo.

"You're right, so Rias Gremory on the list with that is six women. Let's see who will win the hand of our maiden Mikoto-chan."

Ugh, you fucking son of a bitch.

—I finally find you, Mikoto.

I heard Esdeath's voice, she was growing up too, so we had to get her new clothes, the ones she always wore were already unusable.

Haah~, seriously never take that seriously.

For now, his new outfit consisted of a black cap with a metal heart logo, a zip-up coat of white colors and blue lines where the sleeves are oversized, black leather shorts, long black tights that reached his thigh, and white and blue sneakers.

He looked like a sailor if I think about it now.

"Shit why did I forget about her! To the list of romantic interest, well it's seven women... my votes go out to Esdeath and Iryuka... and maybe Rias seems interesting to witness an incestuous relationship in the first person."

How damn you are.

—Why were you looking for me?

—I was thinking of a duel, but I don't think today is the best time, since tomorrow is your birthday.

—Wow, thank you for that consideration.

—Hahaha, there's no point. How about going on a date, let's have fun in that so-called amusement park that the human world has.

"She doesn't waste time, she might win." Sengo said.

—Hmm... Okay, I'd like to do something other than fight today.

The rest of my day was having fun at the amusement park with Esdeath, I had a lot of fun to be honest. Maybe another day I'll do the same, it was a nice place to clear my mind, but Sengo still bothered me that Esdeath can win, seriously annoying that she intrudes on my romantic life.

Now I was sleeping in my room, tomorrow will be my birthday and I'm sure I'll hear comments from Sengo about who can win in a competition that he invented.

6:30 A.M. —

April 9, 2008.

On my 13th birthday.

The other stage of my life begins at adolescence, but something strange had happened this day.

I found myself looking in a full-length mirror at what was on my back.

I had woken up with a slight burning in my back at 6 a.m. that made me jump up.

It's been half an hour looking at what I have on my back, and it was a tattoo of an oni's face.

I really have no way of finding an answer as to why that appeared on my back.

Will it have any important meaning for me?

Haah~, there's no head or tail to look for because that tattoo popped up just today.

So, I'll go to the library to see if I'm lucky to find some information about this, although to be honest I may not find anything.

Several hours later. —

There isn't, there isn't, and there isn't.

I spent the whole day looking through different books and didn't find anything related to oni tattooing.

Haah~, I guess it's time for the party, I'll go back to my room to get dressed in some formal clothes.

I used teleportation magic to get to my room quickly and get dressed, so I wouldn't waste time walking to get to my room.

Already dressed in a formal suit, I used the teleportation magic to get to the room where birthdays have always been celebrated.

As I entered the dazzling room, I saw all the guests chatting happily.

It will be another boring birthday really; it doesn't change anything if new people come.

"I don't think so, I have to see who can have the advantage now on this day."

Sengo said with amusement, he seems to be having fun with my romantic life.

In that I can see Iryuka and Latia chatting near the food table, I think I'll go with them for now.

Oh, there are dangos. I know I'll eat now.

After some time eating dangos and chatting with Iryuka and Latia, Seekvaira-san also came to the conversation along with Sona and Ravel, Rias arrived with Akeno-san and Esdeath a few minutes later, so now we were a group chatting animatedly, although most of them were women and I was the only man in the group.

"You're creating a Harem, you won't make it out alive if that happens, abort that mission soldier!"

I'm not creating a Harem, you wretch!

"Hahahaha, but it looks like you're creating it."

It's not my fault that I get along with women.

"Just in case it's not karma, or something like that of someone who wants to see you suffer for women."

I hope not, because if it were to yes; I don't know what awaits me in the future, maybe murdered by a woman.

"That's more likely to happen if you meet more women, you're sure to meet that so-called yanderes girl."

I hope I'll never meet such a girl.

"I wish you the best of luck to never meet her."

—Hello, Mikoto-tan and Rias-tan; I think I'm a little late to the party and give you my congratulations on your day!

I had heard my older brother's animated voice, but for some strange reason I find him strange, he seemed to be fine, but I see that he is agitated, not from tiredness, but agitated by something.

"Mikoto, I have a hunch of something dangerous coming from your brother."

It's the first time I've heard you talk so seriously, but because something dangerous was going to happen with Sirzechs.

"I told you a long time ago, that I always trusted my instincts, that thanks to that I have saved my life many times, and your brother is dangerous to me now, you need to escape now!"

Seriously because of so much worry, Sirzechs won't do anything dangerous.

—What...

There was the voice of confusion coming from Mikoto as she lowered her gaze to see her older brother's arm.

Where the whole world was left static by the action that Sirzechs Lucifer had done.

No one could believe it, he had stabbed with his right arm burying it in the heart of Mikoto Gremory, his younger brother.

Ugh, shit... I suppose you're right to trust your instincts, Sengo.

Plaf!

Mikoto's lifeless body had hit the ground, no one was moving even after the crashing noise of her fall.

Rias was confused and frozen as she couldn't believe what was happening, she looked at the dead body of her dear brother Mikoto without understanding why her older brother had killed her younger brother.

BECAUSE BECAUSE BECAUSE BECAUSE YOU DID IT!

The cry of hatred echoed throughout the room.
