... Japan, Kuoh Town, Kuoh Academy.
The sky was dyed with the brilliant shade of light by the sun, making it glow beautifully dazzling.
Students could be seen running and sweating under the bright sun.
And Inside the Student Council room.
A white-haired youth and a black- short haired girl wearing glasses were handling official business before them. The white-haired youth was the Student Council President Aleister Astaren, and the Vice President was Souna Shitori.
The originally quiet atmosphere was suddenly interrupted.
Aleister's eyes suddenly widened, and then he covered his forehead with his hand, as if his head was in great pain, his face contorted into a pained grimace.
Souna noticed Aleister's condition, put down the work in her hand, and came behind him. She looked quite worried as she looked at Aleister with a frown.
Souna placed her hand on Aleister's forehead and gently massaged it, "Ester, are you alright?"
"A little uncomfortable." He replied, his voice was dry.
"Then rest well, put this work aside for now."
"Nn, thank you for your hard work, Sona."
After speaking, Aleister then leaned back in his chair and closed his eyes.
Just now, Aleister's brain felt as if it had been violated by something, and then an unfamiliar yet Familiar memory was forcefully inserted into his mind.
After briefly accepting the memories, Aleister was silent for a moment.
Because he had confirmed one thing.
That is... he had actually died and reincarnated into this world! The High School DxD world that was famously erotic from his past life.
And he didn't even know it until now!
That's right, Aleister was reborn not as a human, but he was born into a Pure Blood Devil.
He had just awakened his memories, but the awakening was a bit too rough.
In his previous life, he was an average salaryman who loved eating karaage... No, wait, he was hit by that bastard 'Truck-kun' after he was getting out from a konbini (Convenience Store).
He still remember the pain when he opened the door to get out from the convenience store. A truck had suddenly appeared out of nowhere and rammed at him at high speed, crashing into the convenience store wracking the place real bad.
The only relief he felt was that it was a self serving convenience store and it was mid night, so there's no one else but him in there. What a rotten luck... Or maybe he was lucky?
His real name in this world was Aleister Astaroth, but he could also be called Aleister Astaren in this Human world.
He also came from the Astaroth Family, well... It was a branch family of Astaroth actually.
Of course, his background was quite significant.
He was the younger brother of that Devil King Ajuka Beelzebub, one of the Four Great Devil Kings of the Underworld. If nothing unexpected happened, he should be the next successor of the Astaroth Family.
Why say 'next'?
Because the current head of the family was that nun-obsessed Devil who tricked Asia; that guy hadn't kicked the bucket yet.
After calming down slightly, Aleister opened his eyes and looked at Souna. Sona Sitri that's her real name, Souna Shitori was her name in the human world. She's the heiress of the Sitri Family, his fiancée.
His childhood friend Rias was also the next head of the Gremory Family.
These two were the ones from high school dxd.
After all, he had known them since childhood.
Initially, his elder brother chose Rias as Aleister's primary option. Since his brother and her brother were best friends, a small marriage alliance was not out of the question.
However... his older brother was too late.
The head of the Gremory Family, during a party and him being drunk, arranged Rias's engagement to the yakitori from the Phoenix Family.
Just like in the original story.
And now, Sona's older sister seemed to have changed from a sister-complex to a brother-complex... yes, he was that brother. Sona had also slightly alleviated a large portion of the pressure from his older sister.
He withdrew his gaze and rubbed his once throbbing head, which had already recovered.
Aleister also began to cross-reference the information in his memories.
After checking for a while... Aleister fell silent, spitting out a sentence after a long pause.
"This world is more troublesome than i had expected."
That's right; this world had incorporated other anime worlds besides high school dxd. It was a miracle this fucked up world hasn't collapsed yet.
Simultaneously, in this world, besides Devils, Angels, and Fallen Angels, there were also Evil Spirits, Curse Users, Onmyoji, and so on.
It was truly a motley crew. He was wondering how can Human still alive and not be in chaos? Truly a miracle...
However... in that case, he had quite a few choices for his future peerages.
"Hmm?"
Suddenly, Aleister raised an eyebrow because a light blue virtual screen appeared before him.
[Host: Aleister Astaroth.]
[Bloodline: Pure-Blooded Devil.]
[Abilities: Kankara Formula, Magic Mastery, Magic Power Pool.]
[God Slaying Tools: Innovate Clear, Telos Karma]
[Peerages: None]
[System Ability: Devil Summoning Card.]
Looking at this panel, Aleister was silent for a moment.
Does this kind of cheat system only activate if you awaken your memories? All this years when he still hasn't remembered his past life, he was traininng like mad just to get stronger. Not that it was meaningless, but still... He feels it was a waste of time... Imagine all the things he could do if he has his memories intact from birth.... Sigh.
Eh?! Wait... Is this a reincarnation or a transmigration then? Ah... Who cares, he's still himself anyway, nothing has changed, even his personality was the same even when he doesn't remember his past life.
Then he started reading through the panel carefully.
The Kankara Formula was created by his elder brother.
It was an ability to manipulate the phenomena that occur in the world by using his demonic powers to fill in the calculations of the natural phenomena. By using a specialized magic circle, he is capable of affecting the outside world in various ways.
Simply put, he could control other people's magic by altering the formula and making it stronger or weaker according to his will by using equation and formula.
In terms of magic, Aleister was proficient in some, but he couldn't use the inherited magic of other bloodlines which is obvious.
As for Magic Power Pool, it was something he gained from being sent to this world, it can be said to be a blessing.
His blessing was an endless source of magic power.
However, Aleister had that 'old man looking at his phone' expression when he saw the God Slaying Tool section.
Damn... he actually had Sacred Gears?
Shouldn't these two items be in Mitsuya Kanzaki's hands?
But if they are in my hands, they are mine. And these two items are great treasures.
"Innovate Clear (Miniature Garden of Blue Innovation)."
This item, like the high-tier Sacred Gear 'Dimension Lost,' has the ability to create an ideal world in another dimension. With the additional ability to create nearly-perfect imitations of living beings similarly to 'Annihilation Maker', because of this, it is known as the Sacred Gear That Lets One Impersonate God.
However, anything made inside of Innovate Clear's world can only exist in that world. Innovate Clear can also be used to take control over other barrier spaces. And the consumption of magic power was a bit high which is no problem for the current him.
"Telos Karma (Ultimate Karma/History Breaker)."
A Sacred Gear that could rewrite the laws of things, considered a heretical number (13), and possessed a different kind of danger compared to high-tier Sacred Gears.
It had the ability to guide the possibility of an event towards an impossible choice.
Simply put, it was a Sacred Gear that could modify 'probability' and 'development,' turning the impossible into the possible.
Moreover, the combination of these two was not just 1+1=2.
Aleister's lips curved into a smile. With these two Sacred Gears, his future path, which was already smooth, was now like flying on a fighter jet.
As for his system's ability... [Devil Summoning Card]: The system will place a card summoning him into the countless multiversal worlds, which can be used to summon him.
Damn it!
Tonight, he would return to the Underworld to find his older brother and get that Devil Evil Piece.
He had long since become a High-Ranking Devil.
He just hadn't found the Peerage he wanted, so it had been kept by his elder brother.
At this moment, Sona gently patted his shoulder, "Ester, are you feeling better?"
Aleister snapped back to reality and said with a smile, "I'm fine now, Sona, thank you."
"That's good, want to take a walk with me?"
"Let's go, i won't miss a chance to walk with you, Sona."
The two left the Student Council room and walked hand-in-hand across the school field.
At this time, a commotion nearby attracted their attention.
They saw a bald man, a bespectacled man, and a ridiculous Issei running for their lives, while behind them, they were being chased by the girls from the Kendo Club.
