Issei POV
It has been a week ever since I almost lost my life to my own father,all my bones were downright shattered after that punch even I wondered how I survived. I was in my room getting ready for the country side an underdeveloped and forgotten side of the gremory clan filled with mountain ranges and snow
This past week I've been trying to reach out to the Mana here in the underworld but I don't know why I would feel it and try to absorb it into my body I would be able to feel it but not use it I wonder why
To be honest I'm actually happy, I'm going to be far away from them I can forge my own path, I can achieve my dream of becoming an adventurer and having people who truly care about me
I looked in the mirror revealing the scars on my body especially my back and abdomen and a few on my arms and the most noticable one is a huge scar on the right side of my forehead, I decided to comb all the extra hair towards that side barely missing my eye
He finally crossed the line well then I promise to give him even a worse scar than this
I silently vowed
I opened the door to my room to see my former sister-in-law, grayfia lucifage
Grayfia: Issei it's time
She said dryly
Issei: whatever
I didn't even bat her an eye
She raised an eyebrow a little but quickly lost interest, I packed the little back that I have which was filled with nothing but clothes
As I kept on walking all eyes were on both the servants and guards
" He really did it this time I never saw this coming at all"
" But to think lord gremory would actually attempt to kill his own child"
" Don't let him hear you, loosing your job would be the least of your problem "
I simply ignored their gossips that's the only thing they're good for
Another hateful figure appeared in my sight, he was my ' older brother '
Sirzechs: it seems you are ready
He looked sympathetic
Issei: yes
I said with a flat tone
Sirzechs: I tried to persu...
I decided to interrupt him
Issei: no 1 stop acting like you actually care it's quite pathetic it absolutely makes me sick
No 2 you are no longer my brother and just drop the act I don't bare the gremory name anymore and to be honest is actually the best thing that has actually happened to me in this godamn place
I told him frankly, he was stunned even grayfia
Sirzechs: at least you could...
Issei: get on my knees and beg him, am I mad or something I already vowed that in my ten thousand year lifespan I'm going to give him a worse scar than this
I balled my fist in hatred
Grayfia: don't say such things here boy was it his fault that you were born without anything exceptional
She basically spat at me
Sirzechs: enough grayfia
He warned her sternly
Issei: hmph
I simply put my hands in my pocket and ignored the couple
Grayfia: that brat
She was angry
As I kept walking I felt someone following me
Issei: hmph rias get the hell out here why are you following me
I was on the verge on loosing it, I hate her just as much as those Bastards as parents
Rias: do you really have to leave
She said with a serious face while folding her arms
I wanted to slam her head on a wall
I ignored her and continued Walking
Issei: from now on you are no longer my sister now get the hell out of here
I took a deep breath and looked her right in the eyes
Rias: why can't you know your place and submit to father at least you'll...
I didn't even bother to listen to her and just kept on walking away...how can someone be a bitch at such a young age
Those so called parents didn't even show up I exited the mansion of the gremory clan
I looked back at it one last time and sighed
Issei: this would be the last time I'll ever come here
I saw a carriage and saw grayfia next to it
Grayfia: do you have anything I should tell lord gremory?
Issei: no
I walked into the carriage and closed the door
In a secluded castle in the bael clan
In a study room filled with nothing but books and files lied a man who was sitting down buried In some files, he has wrinkles, dull black hair and violet eyes and was wearing a suit, even though he looked old maybe in his late 50s he looked fit and healthy and his eyes looked sharp
He was zekram bael the former leader of the bael clan
One of his knight ran to him and bowed
Knight: just as you predicted it my lord zeoticus has disowned his own son
Zekram chuckled
Zekram: just like how I predicted
Zekram: good the gremory clan has lost its shining gem
He dropped his pen
The knight was confused
Servant: what do you mean my lord Issei gremory is no different from sairaorg how...
Zekram interrupted him
Zekram: remember when I predicted that two devils would be born that would surpass the previous devil kings especially one from the gremory clan
Yes several centuries ago zeoticus predicted the birth of both sirzechs and ajuka that would surpass the previous devil kings, obviously people didn't believe him until ajuka and sirzechs were born their powers even as children surpassed the norms
As they grew up and truly became super devils, the bael family's prestige even increased more due to zeoticus prediction
Zekram: did you also remember I predicted that a super devil-transcendent would be born from the gremory clan
Knight: yes
He nodded his face was a bit pale
A super devil -transcendent, basically a god
They were rumors like that after witnessing sirzechs and ajuka's power level a transcendent super devil rumor formed
A devil who has basically shed their mortal form and become a true god it was nothing but a myth but it could be
Color drained from the knights face
Knight: are you trying to say that Issei would later become such being... that's impossible his demonic core is broken and under developed how can It be
Zekram: yes
He couldn't doubt that his masters foresight infact It was his powerful insight that allowed him to to lead the anti faction against the old Satan faction
Zekram: and now such gem has fallen out of the gremory's hand
He shook his head
Zekram: zeoticus and sirzechs are fools now Issei grow up and show them what you're resolve and strength, I will support you from the dark
Isseianwhile
Sairaorg:DAMN IT
He slammed his fist on a boulder leaving an imprint
Sairaorg: how could zeoticus do this, how can rias be this evil and sirzechs I can't believe I looked up to you what a joke
He sighed before balling his fist
Misla bael his mother stood behind him watching her son release his rage
Misla: calm down sairaorg even I don't understand why they would do that for such a stupid reason
She sighed
Misla: it seems zeoticus has been looking for a way to disown him
Her and her son's situation in the bael clan was similar to Issei, her position was no better than that of a servant she had no authority same with her son and has been placed in a separate quarter away from the main quarter of the bael castle
Sairaorg: I just worry about him, what if he aims for revenge against the gremory clan
He sighed, like as if he inherited zekram's insight he feels that Issei would one day stand above all devils and that's one of his reasons for getting stronger
She smiled and placed her hand on his shoulder
Misla: it's going to be okay sairaorg trust your little brother and just focus on getting stronger okay
She flashed a bright smile instantly wiping away sairaorg's anger and frustration
Sairaorg: okay mother
He smiled before focusing on his training
Other nobles felt the opposite, some even praised zeoticus for his actions
Why keep a son whose useless and not good at anything
It was the latest news going on in the underworld
Even the subject of the news didn't realize what was going on
It was in the cold region of the gremory clan there were small towns and villages nothing much
As they reached their location some sort of old mansion manifested in the view
He and grayfia left the carriage and took a look at the mansion
Grayfia: this is where you would stay until you've grown or your father has ...
He didn't even let her finish and walked into the mansion not even bothering to even listen to her
She snorted before leaving with the carriage
Issei entered the mansion and noticed that it was not clean, it looked dirty and basically abandoned
He found a broom and began to sweep the leaving room
A few hours later
He managed to clean the house, he was covered in dirt and kept on coughing and wheezing
Issei: this house is so old and basically from what I could see this house has been abandoned for basically more than a hundred years
The person must have been very skilled in magic because the house hasn't fall apart and rotted just became dirty and unkempt
He went to what would be his room and lied dusted the bed before placing his bag on the bed and setting his things
He cracked a smile
Issei: I have to thank that bastard of a brother
of mine, I've basically hit the gold mine
He was excited
He walked down the stairs into the basement and saw a door and opened it
My POV
As if I walked into another dimension I saw something that made my eyes widened and my mouth like ' O '
My eyes wondered around the place
Issei: what the hell is this place
I kept on wondering until I bumped into the magical sphere
A holographic picture of a young man with black hair and green eyes in his mid twenties dressed in some kind of royal outfit, he has a mole next to his lips
Issei: who are you
Deimos: my name is Deimos, Deimos belzeebub
My eyes widened to be honest this is more shocking than the magic library
Issei: how's that possible and what is this place
Deimos looked down at me and smiled
Deimos: this is my legacy all the knowledge I've ever gathered in my life thousands of years of research compiled by m me and my father's research In search of knowledge I travelled different world and realms and complied my knowledge and recorded everything here
He said with a majestic aura
Issei: are you dead?
Deimos: after the great war I was wounded and critically injured by the fallen angel named aizen so I came back here and fused my soul here with this energy sphere
I simply bowed down, Deimos is the first son of belzeebub
Deimos: no worries young devil
Some kind of scanning ray shot at me from head to toe
Deimos: Issei gremory, seven years old, second heir to the gremory clan and unfortunate twin
Issei: unfortunate twin?
His face saddened
Issei: even the son of belzeebub sees me as a mistake
Deimos tilted his head at the child
Deimos: oh you don't know infact you barely have much demonic power, your demonic core is underdeveloped and in terrible condition, you are always sick and find it difficult to breathe you constantly have body pains am I right?
How did he know. I nodded
Deimos: that's simple you are a twin, there's a reason devils don't have twins, the twins will try to absorb the demonic power of the other and most usually stillbirths and if the weaker one manages to survive they would suffer from the illness above and would likely not make it to adult hood
Issei: sir Deimos I've tried to channel Mana into my body...
Deimos: yes it is in your body, you should stop your already little lifespan would even dwindle more it's best you don't
Issei:but how would I get stronger? What about phenex tears
Deimos: all your sufferings is in your genetics phenex tears won't do anything
Tears kept on falling from my eyes
Issei:so I'm destined to be weak, my own sister ruined my life before I was even born why is all this happening to me please is there any other way
Seeing the sad face of the child even Deimos was moved
Deimos: there is but it is very risky
With a wave of his hand a potion appeared it was golden In color
Potion of ascendance: This legendary potion, known as the "Elixir of Ascendancy," is a rare and mystical concoction that holds immense power. Crafted me, it is said to unlock the hidden potential within an individual, bestowing them with unprecedented strength and abilities.
Upon consuming the Potion of ascendance, the user's physical attributes undergo a remarkable transformation. Their strength, speed, and endurance soar to incredible heights, allowing them to perform feats that would normally be considered impossible. They become faster, stronger, and more agile, their entire body is remoulded and perfectly sculpted down to their very DNA
Issei: amazing
Deimos: that's not all The elixir also amplifies the user's magical capabilities. Their connection to magical energies becomes intensified, enabling them to cast spells with greater potency and precision. Whether it's manipulating elements, summoning mystical creatures, or channeling devastating spells, the user's magical prowess reaches an unparalleled level but first ones potential must be immense and strong first
Issei: can I have it?
I said with puppy eyes making him chuckle
His face was very serious
Deimos: if I give you the potion and you succeeded in the transformation what would you do with it
Issei: well I've always wanted to be an adventurer and have friends and people who truly care about me and also help my onee chan become a devil king and also give my father a scar like he gave me
I said raising my forehead
Deimos: not bad not bad just try to survive it and I'll make you my disciple
He smiled
Issei: Survive?
I tilted my head
Deimos: that is... The side effects of you fail you'll die
Issei: to be honest with you I saw it coming, well let's do this
Deimos handed him the potion and he drank it
Issei: taste like apple juice but a little salty
Deimos: wait for it
I scram in agony as my bones and body began to break, I felt pain from every cell in my body I scram in pain and agony
Issei:gaaaaaaah it hurts
Deimos: I wasn't expecting this, his body it's mutating how ?
Deimos wondered
After several hours
Third person POV
Issei was on the ground barely conscious and Deimos looked at him studying his body
Deimos: I can't believe it , due to some random luck and his protagonist halo he was able to pull through I wonder how his body would be after all this, this was very experimental
He pondered
Issei later fell into a coma
