Update: 22/12/2023

Note: I don't speak English, that's why I use translation tools to bring it, this time I will use Microsoft for the translation from Spanish to English of this Fanfic, I have no idea if there are grammatical problems and more. So I'm sorry, for now I bring this prologue, then I will change the Google translation to the Microsoft one these days.

Prologue: Muramasa

Underworld: House Gremory.

The servants of the Gremory family are excited. The reason?

Today, the matriarch of House Gremory: Venelana Gremory is due to give birth.

The demon doctor told them he was going to have twins. They waited months for the birth of the new heirs to House Gremory. They had been without an heir for many years since the day Sirzechs left House Gremory to now be the new Lucifer.

Sirzechs himself with his wife, Grayfia Lucifuge who is also known as the [Queen] of Sirzechs in the Rating Game.

They were on their way through the halls of the grand mansion with a brisk walk to his mother's room to see his new little brothers who had him ecstatic from the first day he received the information.

As he was happily thinking about it, he came across a servant coming out of his mother's room giving information to everyone around the room.

—The little heirs of the Gremory family have been born.

The servant said with a smile that betrayed his attempt to hide his excitement at the time of reporting this fact.

The servants murmured with joy as they watched Sirzechs approach with his wife.

—My little brothers are born! —Sirzechs said, not hiding his joy as he approached the door handle to push open the door to enter his mother's room.

As he approached his mother's bed, he was lying down and saw in his mother's arms the little babies who would now be his younger siblings.

—Hello, mother!

Sirzechs said as he greeted his mother with joy, who began to look at him and smiling at him said.

—Hello Sirzechs, these are your new little brothers. Let me introduce you to this little girl named Rias and this little guy is called...

(Minutes before Sirzechs' arrival)

At the time of the birth of the new heirs of House Gremory. One of the newborns had a confused expression as if he didn't know where he was.

With his eyes he looked everywhere as if he were looking for an answer as to why he was in this place.

He kept looking for several seconds, but unfortunately, he had given up looking for an answer.

He gave a small sigh that caught the attention of the beautiful young woman who was carrying him in her arms.

A hand of hers was guided to one of his cheeks and was stretched slightly, causing the baby to look into the eyes of the beautiful young woman.

(Who the hell is she?)

The little baby wondered, as he tried to guess who it was.

(Hmm... I'm in his arms, and I also realized that I'm very small, maybe I'm a baby? If so... She would be my mother?)

The beautiful young woman saw his confused expression drawing her attention even more.

—You're a weird baby, you know?

The person who would be his "mother" said.

(If I could talk, I'd say no... I have no idea why I have been born again, although I have no memory of my past, for some reason; I know I should be dead.)

Sen.. Muramasa

(Hey! How strange... A strange, incomplete, fuzzy name came into my head... does it mean something from my past that I've lost?)

As the little boy's mind continued to search for more information, he heard the footsteps of a person approaching who interrupted his thoughts.

He saw a man with long crimson red hair, blue eyes, wearing an elegant white suit.

He had a peculiar chin, as if it were a "u" that caught his attention.

(Strange, there are still rare beard shapes for men. Are there any normal ones?)

The little guy thought of things that had nothing to do with the plot, we continued.

—Hello, my dear. I came at the moment to feel the little traces of magic in this room.

The newly arrived man said, the beautiful young woman smiled fondly at him as she lifted the little ones close to him a little.

—Meet your new children, this little one is Rias and this little one is Mikoto.

(Who is Mikoto? My name is ... My name?... What's my name?)

The little boy was in existential doubt as to what his name was.

—If it wasn't for the news that you'd be giving twins, I would have made a deal with the Phenexes for Rias to marry Riser.

(Because the hell you'd do that, the little one doesn't have a time to be born and a bomb has already fallen from a marriage arrangement if there were no twins.)

—But with you, little Mikoto, you will marry Ravel Phenex; Thanks to you you will save your little sister.

(Son of a bitch! Give me freedom of who I'll marry at least! I don't care what other problems your family has!)

Without realizing it, he made an angry face that surprised the two adults a little.

—Haha, what a surprise this little guy got mad at the last thing I said.

—This little boy is very strange, when he was born, he didn't cry like he did with little Rias.

The comments calmed down Mikoto's anger.

(Damn, I've got to act like a baby or else I'll get a lot of attention.)

—Oh, wow; He calmed down quickly. —The man said he would be his "father."

(Shit! What do I have to do to keep him from getting suspicious!)

—It seems that little Mikoto understands our words. —His mother said.

(... They're insightful, what the hell do I do now.)

—Maybe Mikoto is a genius?

As if a ray of hope reached Mikoto, his father's comment ended up saving him from the stormy situation he ended up doing due to his slip of erroneous movements.

(You sir, I don't know how the hell I came to that conclusion, but you saved me.)

—Little Mikoto will take the Gremory family to a higher level!

The mother said, excited by what her husband said.

(You, madam, don't jump to that conclusion.)

Mikoto thought as he felt nervous about his parents' actions.

(Why on earth would he take this family higher? I can't even walk now.)

—I'm sorry little Mikoto, but on your shoulders will fall the weight of the Gremory family as the new heir.

Because I feel like it's not a problem? Maybe it happened in the past? Was he an heir to a well-known family? I'm very curious about knowing my past.)

While Mikoto was thinking about things to do with his past, Mikoto's father started to leave.

—Are you leaving, dear?

—I have to report Rias and Mikoto's birth to the Underworld councilors.

(Underworld? Now I want to know what race I was born into, I know I was a human; But now, what am I?)

—Got it, dear. —His wife said with a smile.

Mikoto watched as her father left the room, after a few seconds a servant came over to watch him.

He ended up retiring once he saw them, and there were murmurs of joy.

(Maybe he told them about Rias and me.)

At that moment the door was heard to open again, and another young man with long crimson red hair and blue eyes entered, but this time accompanied by another person, a beautiful woman with silver hair and eyes, in a maid's outfit.

—Hello, mother!

The newly arrived man said as he happily greeted his mother, who began to look at him and smiling at him said.

—Hello Sirzechs, these are your new little brothers. I present to you this little girl who is called Rias and this little one is called Mikoto.

(So, this would be my older brother, Sirzechs. All people look very young, will they be immortal? A beautiful advantage I have now, I will be young for many years... For some reason I didn't like calling myself "young.")

Mikoto was confused by a single word, as if the word "young" had nothing to do with him.

Maybe he was an old man or an adult? But if that were the case, why does that simple word bother me? I don't think there's going to be a word that can make a person uncomfortable... or maybe it does?)

—Hello little brother, you know that you are the new heir of the Gremory family.

(Yes, I was told that a few minutes ago.)

Sirzechs watched as Mikoto made a bored expression at what he said.

—Mhm! Your face tells me you already know.

(I got bored of trying to hide my emotions, I'll let fate... surprise me?)

For some strange reason, Mikoto felt a little tingle all over her body.

As if some important piece of information had left his thoughts.

(Ugh... Seriously who the hell I was in the past, there are words I said without thinking about it that end up falling like cold water on my body as if it were something important in a puzzle. If I try to uncover my past, I have no idea what it might affect me today.)

(I'd better fall asleep and stop thinking about things that lead me to remember my past.)

Venelana and Sirzechs watched as Mikoto began to sleep.

—He's a weird little brother.

Sirchez said, watching his little brother.

Venelana gave a little laugh. —I thought the same thing, even though your father said he's promising. If he said so, I will quietly entrust Gremory's future in his hands.

The conversation he had continued without any problems, as he thought of a prosperous future in Mikoto's small arms.

|One Year Later|

Mikoto Gremory's room.

Mikoto looked out of her room at her window, surprised to see the "sky" of that world.

(That whole place really only looks dark red, I don't even see a sun, but I see the outside clearly.)

(So, a demon...)

Days after his birth he had discovered that he was a demon, which ended up bringing him a big surprise. His imagination of a demon was very different, he didn't think it would be... "human."

He also got a surprise in the underworld.

On walks that his mother, who he now knew as Venelana Gremory, took as well as his father Zeoticus Gremory.

He was taken in some parts of the so-called "Underworld" to reach various mansions of different families.

They were gatherings of mothers who brought their children to meet their children.

The "Underworld" was... like a big city; There were no scary places as he would have imagined, or maybe there were, but they were in a distant location. He thought about going to those places when he grows up.

(This world is weird; it shatters people's dreams. My imagination of demons and underworld fell apart.)

(Well, all that's left is to discover the gods and other races; I just hope they're not a joke.)

(For now, I'm trying to remember the little information collected. I am Mikoto Gremory, belonging to a family of upper-class demons from the 72 Pillars. Sirzechs Lucifer, elder brother and Maou Lucifer. A position he received after the end of the Civil War for his achievements. Grayfia Lucifuge was an upper-class demon who served the ancient Lucifer, now married to my older brother. Rias Gremory, younger twin sister, as she is a newborn there is no information that stands out. Zeoticus Gremory, my father and the main head of the family. Venelana Gremory, my mother and matriarch of the family, formerly heiress of Bael; Another upper-class demon family. And... I guess Ravel Phenex, my fiancée? I have no information about her, I only know that she is my fiancée, nor can I assure that I will form a relationship with her; So, I'll leave the title of fiancée with a question mark.)

(Hmm, I don't know; I'm missing out on any more information.)

(Perhaps, information from my past, though I'm thinking of leaving it for the future. Let my future self-worry about it, I don't.)

At that moment, the door to his room is heard opening.

Mikoto watches the beautiful servant approaching him.

—Mikoto-sama, it's lunchtime.

(Oh! Seriously, time passes quickly, well I'll enjoy my childhood, as I thought about it, I'll let my future self-worry about it.)

The maid walked over to the little baby who was smiling and raising her small arms for her to carry him.

—Haha! Mikoto-sama, you'll be a glutton if your taste for food gets too big.

(You may or may not be right, haha.)

The baby's little laugh was heard when the servant said that.

The servant closed the room, and continued his walk to the dining-room, where the Gremory family stood; They waited for their children to be carried by the servants.

|One Year Later|

It's been another year, and I couldn't find more important information to highlight. Apart from the fact that I can now walk, talk, and write.

The servants and my parents praised me for this.

I couldn't find the reason why, until I saw my little sister; Rias Gremory.

And I understood why he praised me.

Right now, I'm watching her, she can barely walk well, and she has difficulty pronouncing several words.

She's a normal little girl, the problem; It would be me.

I already have a previous life, with little knowledge.

Whereas Rias, it's a little new life.

He has no knowledge of any other life than this one that has just begun.

For her to be compared to me, that's something they shouldn't do.

This can be a big problem in the future, if she sees that she is seen as inferior to me, it can affect her psychologically. Tsk, I can't allow that. The only thing I can do is help her, but it really looks exhausting to do that. But there's no other choice, I'll have to lend a hand to the servants who are teaching Rias.

Unless she has a decent IQ level of a 4-year-old girl.

...

Tsk, I sense another problem with doing this. A 2-year-old teaching someone his own age will attract a lot of attention.

The only solution I see is to try playing like a little kid, with learning toys. At least that will go unnoticed.

|One Year Later|

—Mikoto-nii-chan.

I was sleeping peacefully at my bedroom window, until I felt someone push me a little and call my name.

I opened my sleepy eyes a little, to see who was calling me.

—What's the matter, Rias?

I saw my little sister who was to blame for interrupting my dreams.

—Let's play Mikoto-nii-chan!

She said with joy and bright eyes.

—I'm sorry, but as you can see, I'm sleeping.

I replied as I closed my eyes again.

—But Mikoto-nii-chan, he's always sleeping!

She complained to me.

—Maybe I have an art for sleeping.

I said.

As I closed my eyes again, something happened.

—That hurts.

I said without any emotion.

—I just have to take you to the yard to play!

She said, as I was carried across the floor outside my room.

It really hurts.

—Well, let me go; I'll walk by myself to the courtyard.

—Do you promise?!

—Yes, I promise.

—Okay!

Rias let go of my arm, and I begin to get up from the floor to walk next to her into the hallway that leads to the courtyard of this mansion.

My body and mind are very sleepy, I really don't want to do any exercise; I want to sleep.

—Hello, Rias-sama and Mikoto-sama.

—Hello Misaki-san!

—Hello.

We greeted the brown-haired maid.

Seriously, the people who work here are of high beauties. Although I don't doubt their domestic skills, they do a perfect job. But there will be a taste problem if I only see beautiful women every day.

I hope I don't have that problem in the future.

—We're here!

Hmm. I didn't realize we had arrived.

I must be careful not to be lost in my thoughts.

—Well, Rias. That we're going to play.

—Hmm?!

I saw Rias's face of joy as he thought of some particular game to play.

—To the burned!

—Hmm? How do you play that?

—We'll play [Rock, Paper, Scissors], and the winner will count down 10 seconds, and the loser will run! Once the 10 seconds are over, the winner has to go after the loser and throw this ball to touch any part of their body!

I would have preferred the [Rock, Paper, Scissors]. Instead of running and tiring my body more.

*Sigh* Well, this will be a start to exercise my body and let go of sleeping.

—I'm in.

—Rock, paper, scissors!

Finish by pulling out paper. Rias pulled out stone.

—I won.

I started running as fast as I could towards the mansion. She never said where running is allowed. So, the entire territory of this mansion is a playground.

I focused my ears on listening to Rias's count, which was already over.

—Here I come, Mikoto-nii-chan!

Heh, this is going to be fun.

|Several Hours Later|

*Yawn*

I was in my room; it was already dark.

I seriously had fun playing like 2 hours on that burn game.

Now my body is fatigued, we were running all over the mansion. Although we were scolded many times for that reason, but we kept playing without caring about that.

Until our mother came along, and we had to stop playing.

*Yawn*

I'd better sleep, I can't sleep much anymore.

—Zzzz...

|One Year Later|

It's been another year, although this time it was very boring. There is nothing that can stand out as exciting or interesting.

I only have information that I will have teachers who will educate me on many things of the Underworld.

I don't think it's interesting, really.

|Six Months Later|

The people who will be my teachers have arrived. They began to teach me the basics of what a demon should know.

Even if you don't think much of it.

I only listened to the information of the Civil War, Pure Blood Demons, Reincarnated Demons and also the romantic history of my older brother and his wife.

It was a story that ended up being brought to the big screen in theaters.

I have no idea what Sirzechs thinks of that, whether he'll be happy or uncomfortable; that everyone knew how his relationship with his wife began.

But I guess he won't care.

Four Great Demon Kings.

This did catch my attention.

Lucifer

Beelzebub

Asmodeus

Leviathan

The names of demons and monsters with the greatest relevance in the Bible.

Although the originals died.

I would have liked to know the originals, but hey, what can be done; I can't grieve in spilt milk.

I heard someone opening the door to my room.

Hmm. He's the teacher.

—Hello, Mikoto-sama. Today we continue to teach arithmetic.

—Got it, master.

Well, another boring class.

|Months Later|

Christmas.

This was weird when I first celebrated Christmas.

He didn't believe that demons celebrated this holiday.

Not that I have any memory of celebrating this, though.

I found it confusing when I read Christmas information.

It's like a birthday for everyone, as they give each other gifts and the family gets together while everyone talks.

—Here, little Mikoto.

Sirzechs said, as he handed me a small wrapper.

A scarf?

So, I'd want a scarf in hell.

—Are you funny, big brother?

—Haha, in the month of Christmas in the human world it's always snowing, so I gave you that.

—But I'm not going to the human world, because I'd wear this scarf in hell where snow never falls.

—It's because this Christmas we're going to take you and Rias to the human world so that he can get to know the snow.

My father said that he was coming near him, my mother, and Rias.

—Oh, what a thrill.

I said boredly.

—Haha, you seriously never change Mikoto.

My mother said.

Well, I don't find it exciting to leave the house just to get to know what snow is.

—Rias and Mikoto, you should change into winter clothes.

I was taken to my room while I was given clothes for the winter.

After a few minutes we went to a magical portal that led us to the human world.

There I got to know the snow and Kuoh City; a city managed by the Gremory family together with the Sitri family.

And also, something important that resonated with my mind.

Japan.

There was a tingle in me.

For some reason my soul longs for this place called Japan.

Other information from my past. Little by little, this puzzle is being put together.

And also, my biggest fear.

Will my being change when I remember my past?

|Two Months Later|

Rias has secured a friend from the Sitri family: Sona Sitri.

The other day Serafall Leviathan had arrived with Sirzechs so that the two girls could get to know each other.

My perception of her bearing the title of Leviathan fell apart.

A magical girl.

*Sigh*

Seriously, Maou are weirdos.

Or do they do it out of boredom?

If so, I'm afraid of my tastes and hobby in the future if I get to have the same level of boredom as the Maou.

Will there be a hobby that can kill that boredom for me in the future?

Another problem for my future self to take care of.

For now, I'll go see how Rias is doing with her new friend.

I walked for a few minutes to Rias' room.

I slowly opened the door without making a sound to look into the room.

I found myself perplexed.

It seems that Rias and Sitri-san were in an argument.

Rias pouted as he held the teddy bear tightly.

And Sitri-san is talking to him with an angry face.

Hmm, I don't know what could have happened; But I'll leave him alone. They must fix their own friendship problems.

I closed the door without making a sound.

I started to pull away and let my own body walk to the place it wants.

There was nothing important to do today. So, now I'll go to the yard; There is a tree where I can sleep peacefully.

Will there ever be a day when I can do something interesting?

For now, I'm having a boring life.

Since I am a child, my parents will not allow me to be in a dangerous exciting situation.

You just have to wait patiently until that day arrives that I can call interesting.

For now, I'll just follow my parents' orders.

Until the day comes when I get bored of following his orders.

Well, I'm going to be 5 years old in a few months, so it's going to be a while before I can do something on my own.

So, I'll get on with my boring life as a little kid.

Time skip. —

Underworld: House Gremory.

April 9, 2000.

This day has come.

Today I turn 5 years old, together with my sister Rias.

There's nothing new when it comes to celebrating our birthday.

But these people are always very happy. As if they were looking forward to this day.

I don't find much importance in celebrating my birthday. But if they are happy, I will celebrate this day without any problem.

I'm not going to ruin your happiness just on a whim.

—Mikoto-nii-chan!

I heard Rias' call behind me.

I made a small circular motion to see it.

She was wearing a pretty white dress, with red buttons in the center, A red ribbon on top. On her neck she had another red ribbon hung on a white cloth necklace, and on top of her little head she wore a white maid-style headdress, who gathered the little pigtails of her long straight red hair.

Mmm? An angel?

It came with a pure white set.

—Hello, Rias. You look very pretty.

—Thank you, Mikoto-nii-chan!

Rias said, as more people came forward to praise Rias' beauty.

Another birthday without anything interesting really.

For now, I'll go to the kitchen, I hope the sweets for the party are ready.

(Kitchen)

Well, I've made it to the kitchen.

I opened the door wide enough so they can hear it open.

Thus, getting the attention of the cooks.

—There's something going on, Mikoto-sama.

I ask the cook closest to me.

—Nothing, really, I just came for some sweets.

—I see, Samuel-san made some Japanese sweets called dango; I hope you like it.

A short-haired, blue-haired, brown-eyed cook. He came with a tray where the sweets called dango were visible.

Pink, white and green.

There were three small colored balls, which were pierced by a spike.

While I was looking at this sweet treat, another cook approached me with green tea.

—From the information I've seen, dango is accompanied by green tea.

I ended up assisting as I picked up the candy and green tea to eat quietly outside the kitchen. He didn't want to interrupt his work any longer.

—Thank you.

They just nodded with a smile.

I closed the door and looked for a place to enjoy dango and green tea.

|Later|

Well, the party is on.

We all sang a birthday song, and then the candle was blown.

But, still, for that big cake shaped like a castle.

I had to tiptoe to blow out the candle. Rias almost fell over it.

A joke perhaps?

Their way of fun is a bit strange.

That aside, the party went off without a hitch.

They are all dancing and laughing.

How would I say this.

Youth? Or old age?

Since they are demons, they can live many years and stay young.

I guess demon stuff.

I looked at the time on the big clock on the wall behind me.

23:42 P.M.

—Mikoto...-nii...-chan... Have... A lot... dream...

Hmm, fate stuff.

—It's all right. I'll take you to your room.

I was going to go to sleep anyway.

—Come, get on my back.

—Under... stand.

Said a sleepy Rias.

He climbed onto my back slowly and settled in as he pleased.

—Mikoto...-nii...-chan... your... back... It's hot... and... comfortable... Zzz.

The little princess fell asleep on my back.

I ended up smiling, being a brother, I think is a rare thing for me.

—Haha.

I gave a little laugh.

—I suppose this life isn't bad.

But I must also look for information from my past.

I will go step by step in search of my past.

If I rush, I can make many mistakes, in the course of my actions.

Maybe when he gets out of the underworld, he'll start looking for information.

For now, I won't do anything.

|One Year and Three Months Later|

*Sigh*

There are 5 months left until the end of this year. And I'm already 6 years old.

I have no idea if time passes slowly or fast.

...

I have a very boring life.

What should I be doing at 6 years old?

Hmm, Rias had her first friend at age 4.

And I'm 6 years old, I don't even have a friend.

Do I start looking for a friend?

Maybe next year, for now I'll enjoy my solitude more.

—Mikoto-nii-chan! Will you join us to play?!

Rias answered the door without worrying about my privacy.

Don't the teachers teach you manners?

Behind her came the heiress of the Sitri family, and now a childhood friend of Rias.

—Can I decline?

Ask if I can refuse that idea of playing.

—No! Now let's go!

I ended up being dragged on the floor like it was a while ago.

—Is it really okay to force your brother to play?

Sitri-san asked as he nervously watched Rias's actions.

I like this girl. I wish Rias was like her.

—Okay! He's my brother, so no problem; of the actions I do with it!

That...

(That's a very misappropriate way of thinking!)

They were the unison thoughts of Sitri and Mikoto.

I was nervous now because of what Rias said.

...

For now, I'll let go of what he said and go on with my life without worrying about meaningless things.

—Okay, Rias. But what will we play?

Sitri-san asked. I also looked at Rias, she's the one who always chooses to play.

—Since there are three of us! We'll play hide and seek!

Rias said excitedly.

Mmm... Well, maybe I can start playing.

—All right, I'll count; You hide yourselves.

Rias and Sitri-san nodded, as they began to hide.

—1... 2...

I started counting, I'm going to start playing more often.

Maybe one day something interesting will happen.

Being cooped up in my room would only make me bored all the time.

From today I will try to change a little.

|Seven Months Later|

We are February 25, 2001.

Less than 2 months from my seventh birthday.

Today a teacher will arrive to teach us magic.

Rias was super happy about the news.

In my case, it was the opposite. It didn't really appeal to me.

These months they were playing with my fists and legs.

For some reason this was more interesting and exciting.

I will learn to use the magic of Destruction, but I will also train my body as a professional wrestler.

Hand-to-hand fighting is more exciting.

—Mikoto-sama, Rias-sama; I'm his magic teacher.

My thoughts were interrupted by the person who had just arrived.

I met Rias in the courtyard to receive the teachings on how to wield our magic of destruction, and more spells that I might not use.

—Magic is very simple to learn and use, you only have to follow 4 steps: Imagination; what you want to do, Concentration; to imagine in detail what you want, magic formula; it would be what elements and correct amount of magic to use, and the Will; it would be like materializing the spell with the will using it in conjunction with magic. By following those 4 steps and with a productive workout, the day will come when you will use your magic as if it were breathing; Fire.

The Master summoned a small fire in his palm, and underneath it was a small magic circle.

—Now try to use your magic.

|Six Months Later|

I'm 7 years old now.

Since we had received a magic master, I have been practicing every day in my spare time.

He also practiced hitting a tree, punching, and kicking. And I started exercising my body, I realized that my body was very weak, maybe spending a lot of time sleeping made my body very weak from the average demon child.

So, I find myself running in Gremory territory every day.

It has 200 km², it is very exhausting; I can barely reach the tip on the other side and faint from exhaustion, if it weren't for the servants who are watching me, my life would have been in several critical situations.

He had heard of a reincarnated demon who had gone insane, and he was going around killing any unfortunate demon that came on his assassination radar.

He has slain 115 demons; pure-blooded and reincarnated equally.

This demon didn't care who you were, it would just kill you and quench its bloodlust with you.

The Gremory territory is very large, maybe this demon is hiding in dark places or maybe in normal places while pretending that it was a normal demon and not a murderer.

If so, the demon is very confident in his abilities to go unnoticed by the demons who were always passing by, looking for a trace of him.

For now, I hope I never find it.

I can't imagine facing him and fighting him.

I'm still very weak.

Hmm, I'm getting closer in the middle of Gremory territory.

The only reason why I know that is because of the store I find staring at from afar.

I looked at the geography of the territory when I started running every day, I was looking for half of the territory and also a house or area that was well known to carry the chord of my arrival time.

That's how I got to know the dining room I'm approaching in a stalemate of my tiredness.

The lady who owns the place ended up seeing me fall to the floor from exhaustion.

—Fufu, Mikoto-chan. You've improved your time to get to my dining room.

Said the owner of the place as she used her arms to carry me and carried me to a piece of furniture.

—I'm sorry... I'm full of sweat... I'm sorry to get you dirty...

I responded with shortness of breath and dizziness in my head.

Doing this kind of exercise is sloppy.

—Fufu, don't worry. I've gotten used to doing this since you started arriving at my place, at a standstill.

—Thank you... Elisa-san...

Elisa-san is a beautiful woman with short light blue hair that reached her shoulders, she had braids gathered over her ears that she guided to the back of her head; where you could see a lock of hair sticking out of it, she has beautiful dark violet eyes; He was dressed in a light blue sweater, and short dark blue pants that reached about 12 cm below his knee.

In the left fringe of her hair, she wears a star bincha with a wing, it is something that I had given her for the kindness of having taken care of me.

She has no obligation to be taking care of me, so I am grateful for her kindness.

—How much... time... Delayed?

I haven't recovered yet; I'll be resting on the furniture for several minutes.

—You took a lot of time off your time.

Look into your eyes for him to say the answer.

—This time it was 30 minutes less.

She said smiling.

Yesterday it took me 4 hours and 30 minutes.

Now it's 4 hours.

It's a lot of progress. The first day it took me 8 hours to arrive.

Although that first day I was using strengthening magic on my body to increase my speed, performance, and endurance.

I had a lot of trouble using my magic, I couldn't perfectly concentrate the strengthening magic on me, I ended up falling many times on the way to get to Elisa-san's premises.

She ended up healing my slight wounds.

I really need to have a stronger body. A body that cannot be hurt, a body with an iron hardness. I need to get a body like that, so I don't worry the people who are important to me.

For now, I'll sleep to regain my energy.

|Thirty Minutes Later|

—Ahh!

My body was alarmed by Elisa-san's scream of terror. I looked at Elisa-san's look of horror, as you used your hands to cover her mouth, Elisa-san's whole body trembled with fear.

At that moment, the smell of blood-contaminated iron reached my nose.

I focused my ears to hear the footsteps approaching this more exact place, approaching Elisa-san.

That set off alarm bells in my head.

Elisa-san was in great danger.

My eyes saw a demon smiling like a maniac while in his right hand he held a katana that expelled bloodlust, which also surrounded the demon's body.

The katana had a signature near the hilt.

Muramasa

I felt a little connection to the name and the katana.

Maybe I'm closer to finding my past than I imagined?

I'll stop thinking about that for now.

The * had begun to raise the katana that was aimed at Elisa-san.

My mind went blank.

He could observe the bastard's movements in slow motion as well as Elisa-san who wanted to save her life by walking away from him.

I have no idea what's going on, but I'll take advantage of this. The bastard's body is very helpless, I just have to strengthen my arms to pierce his chest...

Your chest is no longer likely to survive.

To kill him fast, I have to pierce his heart.

As I put my right arm close to the bastard's heart, I received a strong kick.

—You're amazing little one, if it wasn't for my instincts, I would have had a certain death!

I saw the maniacal grin as he prepares his body in a battle pose.

I was lying near Elisa-san.

Tsk, I dislocated my right arm.

I took his kick squarely.

—Mikoto-chan! You must get out of this place; you're going to die!

I listened to Elisa-san with a frightened expression as she worried about me.

—You're going to die too if I don't do anything.

The demons after the Civil War now lead a very carefree life.

They are weak now.

Hard times, it creates strong people; Strong people create easy times and easy times create weak people.

Tsk, I would have taken seriously training my body over a year ago, instead of slacking off.

(There's nothing interesting this year, maybe in the future something interesting can come along for me.)

Ha, I always thought that. Now I'm getting what I've been looking for.

—Even if you're right, you're a child; You can't endanger your life!

Tsk, I'm very weak.

—Hahaha! If you have already spoken your last words, now DIE!

There came another killing attack from the bastard.

My perception saw the movements around me back in slow motion.

I'll think later why that is.

Now I have to think quickly of a move.

Should I grab Elisa-san and escape? Attack again? Be a decoy? Hold out until my bodyguards arrive? Fight and die?

Several actions came to my mind. Even one I didn't like.

Run away and abandon Elisa-san?

This thought ended up torturing my head.

Because I would abandon her, if she has helped me many times without receiving some obligation to take care of a silly child who is always running around every day.

I have to repay their gratitude for taking care of me.

I strengthened my body with magic, I didn't care if I broke a bone.

If I attack straight back to his heart, I would get a seizure that I deflected back to the floor.

If I attack your head on the right side, you will try to defend it with your forearm or the same hand.

And if he can't defend himself in time, I'll just crack his skull with all the force of my kick.

—Damn child! You're really fast! But thanks to my instinct I can defend myself against your kick—AAAHHH!

It hurts, it really hurts.

My right foot had been broken as well.

But now he will no longer be able to use his right arm that held the katana.

I've got to go fast and grab that katana.

When he ran, he almost ended up falling.

Tsk, having a broken foot left me unbalanced.

But I must reach the katana quickly before he can grasp it.

—DAMN CHILD! I WON'T LET HIM GRAB MY KATANA!

Shit, shit, shit.

The damn bastard is just a few inches away from reaching the katana.

There is no other choice.

I'll have to sacrifice my left foot.

I strengthened my left foot to such an exaggerated level that I could feel the blood circulation stopping.

It didn't matter, now I have to kill him.

His body was helpless as he bent down to grab the katana.

A heavy kick to his head would kill him instantly.

I have to go faster; I can't let him get away or defend himself now.

...

I watched as my kick slowly approached. There was no escape for him, it's my victory.

KRACK!

My head was carefully recording the horrific event in front of me.

The force of my kick...

He was loaded with more power than he imagined.

The bastard's head had exploded, and all my brains were falling on my face and soiling all my clothes with his blood.

I could see well... his brain in pieces, his tongue in the open and how blood was pouring out of his throat... And how he made a pool of blood around the dead body.

A disgusting scene... that I committed myself.

But the most worrying thing was...

I didn't feel anything the moment I realized I killed him.

As if I'm already used to doing this.

I began to tremble with fear at this fact.

Elisa-san finishing, hugging me from behind as she used her hand to tenderly stroke my hair.

—Ya, ya, ya. Don't worry, Mikoto-chan, I know you're trembling because of what you've done. But don't think what you did this wrong, you just saved the lives of many demons as well as my life.

Elisa-san said with an awkward smile.

The idea that a 7-year-old boy killed a strong demon can terrify people.

Elisa-san ended up coming up with a misconception as to why my body is shaking, afraid that I have killed.

But it didn't.

My fear was not feeling anything, any particular emotion, A void.

I had no doubt, remorse, or sadness about killing someone.

A person without a feeling at the time of killing is a dangerous person.

Will I become a dangerous person too?

Will I be a danger in the future?

Questions that tormented my head.

I'm afraid for my future.

|Astaroth Territory|

Zeoticus had traveled to meet an old friend.

Lord Astaroth.

They had talked about many things in the past.

Also, valuable information on how to lead your family to gain more power in the underworld.

And they ended up coming to his son: Mikoto.

—Your son is an exceptional boy; a great future awaits him and your family.

All the demons around Mikoto always thought she was a genius demon.

He was a quick learner and quickly executed the teachings always given.

As for his sister Rias.

They thought he was a decent demon, his IQ was that of a normal kid, he was always distracted and looking to play. That's why his learning was mediocre compared to his brother.

The demons felt safe for the person who was going to inherit the Gremory family.

They had high expectations of Mikoto Gremory.

—Thank you; My wife feels the same way I do. Mikoto as heir was a blessing to Gremory. As for her sister, her learning is slow but sure. Still, he has nothing to worry about, Mikoto is the one who will get the most attention in the future as Gremory's Leader. Rias just needs to enjoy his life and not make mistakes that lead to a big problem for the Gremorys.

—It's a shame for your daughter, that no one has high expectations of her.

—You may be right, but no one can know and control a person's fate, it's like a dice game, you'll have good numbers, or you'll have bad numbers. Mikoto got the good numbers and Rías got the bad numbers, their lives will have different successes in the future, it can be good, or it can be bad. Only fate itself knows that answer.

Although Zeoticus said that years ago when his son was months old. He had forced doctors to draw his blood to look for the best genes to put together in a marriage to have a better lineage.

From so much searching to form and create a powerful lineage for the future. She had come to the same answer he had thought of in the past.

Phenex family.

He had been called crazy. But when they saw this result, they exchanged their crooked personality for a great success for Lord Gremory.

Destruction + Immortality.

Two words, two powers; in a person. Also known as Gods.

The Gods are immortal and destroyers. Mikoto Gremory's next lineage with Ravel Phenex, will bring a Demon with the same level of a God.

This person who said that no one can control a person's destiny.

He was playing with the very fate of his own son.

Lord Astaroth saw how Zeoticus had an evil smile.

(I feel a little sorry for his son, but I can't say anything. Demons are like that, if there is an advantage to getting more power, we would take that advantage without batting an eyelid. Haah, it's a shame that Ajuka has become a Maou. For now, I'll be seeing if Diodora is someone I can take on as Clan Leader Astaroth, hopefully it won't become a headache in the future.)

Lord Astaroth never realized that his sons were equal to the sons of Zeoticus.

One was blessed by a good future, and the other by a tragic future blamed for the downfall of his clan.

Time skip. —

Underworld: House Gremory.

I was in my room, a few days after the accident.

People were amazed that they had killed a strong demon.

But I don't care about that now.

I have one more important matter to attend to.

I had taken the mad demon's katana.

I had started looking for my past, I asked my older brother Sirzechs Lucifer for help.

What will you be looking for information about Muramasa?

Although he asked me the reason for that, I told him that I was interested in katana so he wouldn't ask too much.

I don't ask any more since Muramasa was a blacksmith, maybe he thought he was interested in blacksmithing and with the information he was looking for he was going to start learning how to forge.

But if it came to that idea, he was wrong.

Muramasa is somehow intertwined with my past that I have lost.

So, I read the document given by my brother, while he was at rest.

Since I'm a demon, my recovery was higher than humans.

So, after 4 days I'm putting the information in order.

I went to get my blackboard and drew a straight horizontal line, with several short vertical lines where I filled in the names and date that was very important, while in my mind I thought about the other details I read.

Starting with the 3 generations that are known of Muramasa.

Muramasa I (Shodai Muramasa) later known as 'Myōhō Muramasa' after the katana he forged.

He was active from 1489-1521.

Muramasa II (Nidai Muramasa) is the most famous generation for the beginning of the legend of the cursed katana.

He was active from 1532-1539.

Muramasa III (Sandai Muramasa) the decline of the Muramasa School, the rumors of the cursed katana was taken seriously after seeing people murdering and committing seppuku.

The straw that broke the camel's back was the death of the Shōgun: Tokugawa Nobuyasu.

He had committed seppuku with a Muramasa katana.

He was active from 1573-1592.

In the years of Muramasa III there was a Masashige attached to him (Muramasa III) (younger brother, disciple, or son?).

There was no way to know that.

But with that we draw another line far from Muramasa I, coming to 1456, Musashige I; He died that year.

Known as Musashige Senko.

He was born in 1403 and is said to have been the first disciple of a Muramasa (?).

By then, the first school had already been established in the 1300s.

Maybe the school was born in 1380?

Draw another line away but this time from Musashige I.

I wrote down the name and year of another person who was in Muramasa's information and was...

Gorō Nyūdō Masamune (1264–1343)

Another important name in Muramasa's information.

Rumor has it that he had a Muramasa (?) as a disciple.

But the years do not come enough to become a disciple of Masamune.

The answer is that he was never his disciple.

Perhaps the blood descendant of that Masamune knew Muramasa (?) who later founded the Muramasa School.

...

Hold on...

Masamune did not have a blood descendant.

He had an adopted son named Hikoshirō Sadamune.

He was born in 1298 and died in 1349.

Even this adopted son didn't get to meet Muramasa (?).

Tsk.

...

...

In that moment of uncertainty my mind came to another logic that I didn't want to think about.

Letting my face have a surprised expression.

Maybe... just maybe, the fantasy that he was a disciple of Masamune was real and not a silly legend.

And if that were true, the Muramasa School would have existed before 1350.

Masamune died at the age of 79 (1343).

Maybe Muramasa (?) You were 69 years old at the time of your death.

In the legend it spoke of a competition between the two of them.

If it were true, the competition had to be in the golden moment of the two blacksmiths.

Masamune would have been 40 years old and Muramasa (?) 30 years old.

If so, Muramasa had to open his own school at age 26 or maybe 30.

Leaving with 2 dates, 1300 or 1304; the creation of the Muramasa School.

Like Muramasa (?), he was a blacksmith, just like Masamune; His life span could not exceed 75-80 years. Or it could even have been less.

If all this were true. So, there were 4 or 5 generations of Muramasa.

...

But why is there no name for these generations of Muramasa?

Did they exist or did they not exist?

There is information of the first active Muramasa beginning in 1489.

Musashige spoke of him being a disciple of Muramasa (?), he was in the years 1403 (his birth) to 1456 (his death).

Let's suppose that Muramasa (?), died at the age of 80, which would be in 1354.

Then the first successor to the Muramasa School would begin.

As Muramasa had no descendants, the best student had to become the successor of the school...

Didn't Muramasa really have any descendants (?)?

There's something that doesn't enter my head.

His master Masamune didn't have a descendant, he didn't have his own descendant either.

The Masamune school after 1400 ceased to be important.

There are 2 lost generations of the Muramasa school.

Musashige met a Muramasa and was his teacher.

I can think of another logic as after Muramasa's death (?), the school was closed, if that was the case; there is more than half a century lost until another Muramasa who was Musashige's teacher is known again... a descendant who went into hiding or was hidden?

And because the founder Muramasa is named the same (?).

Why wasn't another name given?

Identity theft?

Is there a race that can change its appearance to that of a human and take on the appearance of another?

Damn, I really need to get out of hell if I want to find more of an answer!

...

Tsk, for now I can only wait until you allow me to get out of hell.

...

But when will that day be?

|Year 1298, Japan: Kamakura City; Sagami Province|

On a dirt walk with several trees around it, you could see a silhouette of an adult male with short red hair and eyes the color of his hair, he had gone off the path into the vast forest.

After a few minutes I came to a small river that had a small waterfall.

He walked over near the river and sat down on a large stone that was enough even to lie down and look at the vast sunlit sky.

He brought his legs across as you stretched out his arms touching his knees, and then closed his eyes.

I had begun to meditate.

Or maybe not.

—And now why are you meditating, Sengo?

A voice had been heard coming from the road that the red-haired man had come.

At that moment the red-haired man opened his eyes again to look at the person behind him.

A beautiful woman maybe in her 30s. She has cute long white hair, beautiful golden eyes mesmerized for her eyesight. She was wearing a beautiful elegant purple kimono, with cherry blossom designs. And there was a beautiful smile on her face.

The background of the cherry forest added to her beauty, as if she were a goddess.

—Hmm, thinking why the hell would I accept that deal in our competition, Masamune.

—Seriously, it's been 1 year now; I can't believe you can't get over that...

At that moment the small cry of a baby was heard on Masamune's back.

Masamune carefully moved the baby to hold him in his arms and began to move delicately from side to side while humming a soothing melody that took effect on the baby to relax and go back to sleep.

—Do you want to hold your son?

Masamune said as he watched Sengo in amusement.

—Tsk, get that brat away from me. —Sengo grimaced in disgust. —Seriously, because the hell I accepted that competition of the loser who would obey an order without objection.

—Blame your arrogance, you wanted a challenge, although I could understand why you were confident of winning, but you still have years to beat me. I'm 32 years old and you're 25 years old, I'm 7 years apart in terms of blacksmithing skills.

Sengo had trusted his abilities and challenged his master, Masamune.

Where he ended up losing, and after his defeat had come Masamune's order.

(A son... I seriously have a son, besides having a child; I'm also married.)

(Tsk, now I don't know which is worse, being married or having a child.)

—Now, now, calm down, you can't be forever denying what has already been done.

—Tsk, because I wouldn't be, after all you chose to have a child with me, a cursed being. There were better people with a better lineage that you can contract for a better future for your family, but you ruined that prosperous future for someone cursed and disreputable.

Masamune gave a small laugh as she watched Sengo's scandals of how he worried about a better future for her.

He may be right, there were better men with a better lineage to marry and move up the ranks of his family. But Sengo had forgotten that he himself had raised his family to the 5th Rank, making the Muramasa a Noble family, equal to the Masamune. In terms of power, the two are evenly matched.

At that moment, as she carefully left the little baby on her lap sleeping, she brought her hands to Sengo's cheeks and forced him to stare into her golden eyes.

—It's because I love you.

—Huh?

Sengo ended up letting out a confused and funny groan.

If a person's face could fall apart because of something unexpected, then at that moment Seng's face would have fallen because of how surprising Masamune was.

After a few seconds, Sengo had recovered from his surprise.

—Tsk, love is a troublesome and annoying thing. —Sengo said as he brought his right hand to where his heart is and where he felt the heartbeat that began to beat a little fast.

Masamune smiled a little at Sengo's actions. —Okay, I won't force you to fall in love with me... But I might start making moves for you to fall in love with me. —He finished with an amused smile.

—I'd rather talk about something other than romance. —Sengo said with a grimace.

Masamune took into account what he said, maybe another day it will continue to bother him.

So, he thought of another topic that he could talk about, and a certain Clan came into his head.

—By the way, Sengo, how is the Hōjō Clan doing?

—They're calm for now, but rumor has it that they're controlling the Shōgun: Prince Hisaaki.

—Are you going to have another war?

—Haah, I hope not, if there's another war; All blacksmiths will be forced to forge weapons for them. Seriously, they don't get tired of committing atrocities just to get more power. If they continue like this, in a few years that Clan will be overthrown.

—The Hōjō Clan is crazy, and even their only ally, Adachi Clan, is crazy. —Masamune said.

—What can I say, when someone is obsessed with power, they are capable of killing their allies.

(Although it is rumored that the Adachi Clan had already thought of attacking the Hōjō Clan to take all power from them.) Sengo thought.

—Did you get information from the Emperor? —Sengo asked.

—They're like the calm sea, though a storm can come out at any moment. They have internal problems of who is going to become the new Emperor.

—I'd like them to take it easy on the successor, 8 years ago they almost killed the current Emperor.

Masamune sighed. —Becoming the Emperor of Japan is the most coveted power in the imperial family, they would commit atrocities of killing their own brother just to have that power.

Sigh. —Is there going to be a year where you can enjoy life quietly? —Sengo asked as he watched the skies.

—We're blacksmiths, I don't think our work is the quietest for life, and we live in a place where you always want to go to war like you're the strongest men in the world. —Masamune said.

At that moment, Sengo and Masamune's eyes had seen something strange in the waterfall that ended up falling and was carried away by the current near them.
