Multiverse, Infinite Dimensions Starting from The Irregular at Magic High School
Author: Lemon Head
My name was Yotsuba Mahiro. I was a transmigrator.
An envoy of interdimensional transport sent me to the world of The Irregular at Magic High School, where I also became an adjusted magician of the Yotsuba Family.
Aside from being born with a pair of eyes capable of copying any magic and martial art, perhaps my greatest backing was my nominal mother, Maya Yotsuba.
After spending fifteen years in the pitch-black Fourth Laboratory, that nominal mother suddenly handed him an important mission—
"Although you are an adjusted magician of the Fourth Laboratory, you are also my child."
"Therefore, producing an outstanding heir for the Yotsuba Family is also your duty."
Wasn't it just carrying on the family line? That was simple enough.
Would the bloodlines of the Ten Master Clans and the Hundred Families be enough?
What if his sister Miya was added to the mix?
And the little girls from Black Bullet World?
What about the assassination group from Akame ga Kill World?
Then how about adding a songstress produced by Guilty Crown?
After experiencing ten worlds, he asked Maya again.
"Is it enough now? If not, I can add more!"

Volume One: The Beginning of The Irregular at Magic High School
I, Yotsuba Mahiro, Am Going to School?
"Nihility!"
[Target successfully eliminated] [Activation time: 68 ms] [Error: 0] [Evaluation: Pass]
A cold mechanical voice echoed through the laboratory of the Fourth Research Institute.
At the very center of the institute's testing grounds.
As the billowing dust gradually dispersed, a bare-chested youth slowly emerged from within.
His frame looked rather lean, yet the lines of his muscles were strikingly defined.
His handsome features, as though carefully carved, made him seem almost like an artificial creation.
The only thing slightly out of place was his pair of eyes.
Black and profound, yet carrying the warmth of humanity.
His name was Yotsuba Mahiro.
More accurately, though, Yotsuba was merely the family he belonged to. He had never received true recognition from the main house.
And Mahiro himself was a transmigrator.
He had originally intended to go out shopping, only to receive the fierce baptism of the Hundred-Ton King.
The good news was that he had not been sent to Warhammer or Dark Souls.
The bad news was that he had been sent to the world of The Irregular at Magic High School, where technology had taken magic to absurd heights and which was known as the anti-China fantasy world.
Fortunately, however—
He had reincarnated into one of the Ten Master Clans.
The so-called Ten Master Clans were the ten families that ruled Japan's magical world.
They were a magical organization composed of the Ichijou, Futaki, Mitsuya, Yotsuba, Itsuwa, Mutsuzuka, Saegusa, Yashiro, Kudou, and Jumonji families.
Naturally, there were other candidate families besides those ten.
Unfortunately, though, the place he had reincarnated into was the Yotsuba Family.
And the Yotsuba Family's Magic Skill Engineer Development Research Institute was an even less humane place.
Besides being abbreviated as the Fourth Laboratory, it also had another name: the Death Research Institute.
That was the place beneath his feet.
But most unfortunate of all, he also had a mother who constantly wanted to kill him—
"My, Mahiro, you really are as outstanding as ever."
Speak of Cao Cao, and Cao Cao arrived.
Just hearing that scalp-tingling voice told him it was his nominal mother.
A peerlessly beautiful woman with black hair.
She possessed a head of hair anyone would envy. Even tied in a ponytail, it still looked so lush and voluminous.
Aside from her outrageously ample chest, her snow-white skin, the beauty mark at the corner of her eye, those seductive red lips, her noblewoman-like elegance, and that enchanting, beautiful queenly aura...
Those were practically all exclusive labels belonging to this woman.
And this woman, who so often wore an elegant smile that made her impossible to read, was his nominal mother—
The head of the Yotsuba Family, Maya Yotsuba.
"Oh, long time no see. How rare for the great head of the Yotsuba Family to come visit me."
Mahiro's tone was full of frivolity and mockery, without the slightest hint of politeness.
Especially that deliberately emphasized form of address.
It greatly displeased Hayama, the butler following Maya, who was already over seventy years old.
But before he could reprimand Mahiro, Maya had already stepped forward.
The crisp click of her slender heels against the floor accompanied her casual, languid, and alluring voice.
"What a disobedient child. Even I would feel hurt if my own child treated me like this~"
"Is that so? What a pity. I couldn't tell where you were hurt at all."
"My, my. Disobedient children must be punished, you know."
The moment she finished speaking.
Pitch-black "night" rapidly spread from beneath Maya's feet.
In the blink of an eye, the entire testing ground was enveloped within her night barrier.
Brilliant stars appeared within the darkness.
The pure white ceiling transformed into a moonless night sky, with meteors tracing streams of flowing light.
It looked like a real night sky.
This was the trump card that earned the woman before him the title Queen of the Dark Night—
The composite magic, "Meteor Shower."
Under the witch's control, the glittering stars in the night sky abruptly stopped moving and transformed into countless beams of light that shot toward Mahiro.
"Parade of Disguise."
Facing this witch who attacked at the slightest disagreement, Mahiro did not hesitate in the least and immediately activated his magic.
The next second, every beam of light struck his body.
Yet strangely, those rays passed straight through his body's surface!
Maya Yotsuba's expression changed slightly, and a meaningful look surfaced in her eyes, carrying what seemed to be anticipation and pride.
But it lasted only an instant before she returned to that elegant smile that made her impossible to read.
"Hehe, very impressive, Mahiro. I never expected your Parade of Disguise to become so proficient already."
"Is it better than your teacher, Kudo Retsu?"
The magic known as Parade of Disguise did not belong to the Yotsuba Clan.
The Yotsuba Family specialized in mental magic.
Parade of Disguise, or Parade, was an illusion magic of the information manipulation type. It had originally been a secret art of the Kudou Family.
But through a certain coincidence, he had stolen it with a single glance.
In fact, even Maya Yotsuba's "Night" had long since been mastered by him and committed to memory.
He even had at least ten ways to kill the woman before him.
But there was no need for that.
Killing this witch would bring him no benefit whatsoever.
Besides, she was his mother in name.
Though for this mother and son, that title was merely a title.
"Hehe."
Maya did not answer his question directly. Instead, she crossed her arms and chuckled. "It is a good thing to be able to use it proficiently, but do not use this magic carelessly when you are out. It could bring trouble to the Yotsuba Clan."
"Out?"
Mahiro's gaze toward the woman gradually turned strange. "You're willing to let this 'monster' leave the Fourth Laboratory?"
He had been in this world for fifteen years.
Yet he could count the number of times he had gone outside on his fingers; even in total, it had not reached ten.
His food, clothing, shelter, and transportation were all handled in the Fourth Laboratory on Mashima Island. Even days when he could go outside and see the sunlight were rare.
Aside from Maya Yotsuba of the main family, the other branch families essentially feared him like a tiger.
And now she was talking about him going outside?
Was she joking?
"You shouldn't put it that way."
For once.
Maya Yotsuba swayed forward with graceful steps, arrived before him, and lifted her head to gaze at him "affectionately."
"No matter what, you are still my child. And now that you are sixteen, it is time for you to go out and see the vast world."
"...What exactly are you planning?"
He did not believe this witch could be so kind-hearted. "Aren't you afraid that the moment I step out of the Yotsuba gates, I'll run away?"
"You won't."
Maya stepped closer, her clear violet gemstone-like eyes reflecting his figure.
"I am your mother. I believe you would not do that. Besides, I will assign you a 'watcher,' and I will contact you regularly as well."
There it was. That was more like it.
"So what kind of scheme are you plotting this time?"
"Nothing. I just want you to go to school."
"Oh... huh???"
