"Test number five… successful."
Isshun glanced down at the pencil resting neatly on his desk, its atoms intact and unspliced. A small, satisfied smile tugged at his lips.
This puts a smile on my face.
Teleportation was a deceptively troublesome ability, mainly because in his case, it wasn't a naturally self-regulating phenomenon the way most Quirks were.
This meant that he couldn't just 'cheat' and hope for the best.
It wasn't like Endeavor, who didn't need to consciously calculate oxygen ignition or heat expansion every time he used his flames. That man could just think of fire hot and his body would probably combust into flames.
While it did have some similarities with the Personal Realities of Espers, they still worked in opposite ways.
Most Quirks acted like extensions of the body.
Once activated, the mutation handled the technical details automatically, compensating for human error.
Isshun's Teleportation from the Shirai Kuroko Template offered no such assistance.
In essence, it lacked an internal correction mechanism. The ability responded exactly to what he calculated through formulas with practically no margin of error.
Success depended entirely on his ability to define space, distance, and orientation within vector space.
While Quirks primarily compensated for human error, Teleportation was the complete opposite.
Teleportation, or more specifically Shirai Kuroko's Teleportation worked on the basis that the user themselves are the 'Reference Point'.
While this undeniably made the calculation process much easier as a result, it had a lack of flexibility.
Ironically, that lack of flexibility was what made it learnable.
It had taken Isshun roughly one year to teleport reliably using himself as the reference point without disorientation, misalignment, or cellular damage.
Rather, due to the constant intake of sensory data due to the Mutant changes brought by Precognition and passive utilization of his computation, Isshun could even say his computative abilities surpassed that of Shirai Kuroko.
Processing vectors, distances, and mass distributions came almost reflexively to him now.
It wouldn't be as exaggerated as teleporting an entire house to a different location, it was entirely plausible for Isshun to teleport cars.
Isshun hadn't had the opportunity to experiment on distance, but that was for another time.
ROB hadn't said that he would be limited to how strong Shirai Kuroko was in the Toaru Universe.
Well, that extent would still undoubtedly be overpowered in this universe.
After all, was it even possible to dodge an instantaneous attack which could result in an instant K.O. with an object placed directly into their head?
Enough digression.
After a few experiments on Teleportation without using himself as a reference point, what Isshun discovered was that… attempting to use Teleportation without any reference point was near impossible with his Personal Reality.
The Earth was never stationary in the universe, with the Earth constantly in movement. And in order to prevent any accidental murders or splicing, Isshun gave up on that route.
However, moving things around him using himself as the reference point was plausible.
The reason why Shirai Kuroko couldn't move anything without being in contact with that object or person was that Teleporting mainly involved moving objects away from the origin point(herself) through the 11th Dimension.
What Isshun was doing was creating a domain where he himself was the origin point as a reference point, not the takeoff point.
This normally wouldn't be possible, but with the combination of the main effect of his Quirk, which granted him a near omnipresent awareness, it was equally as easy to make a graph on everything around him.
What happened just now was an attempt at teleporting a pencil on the floor to the desk without any issues.
And it was successful.
Maybe I am a genius after all?
Isshun stretched and let out a tired breath.
"Well, that's enough experimenting for the day, might as well take a nap—"
…Of course.
Before he could even reach his bed, he sighed and shuffled toward the window. He pulled the curtains open just in time for—
BANG! BANG! BANG!
"Shun-chaaan!! Wanna go play?!"
This girl and that beaming smile.
"...Nejire."
"Yeah?" She tilted her head, eyes sparkling.
Isshun hesitated for half a second before sighing.
"…Sure."
They said you couldn't spit on a smiling face.
Turns out, they were right.
"Nice!"
--<>--
Now in the Shunkan Family's backyard, Nejire put her hands on her hips in contemplation.
"So, what should we do?"
You have to be kidding me.
"I'm going back."
Before Isshun could take even one step, a pair of hands latched onto his shoulders.
"Waiiit! I was just joking," Nejire whined. "Ehe…?"
"What was that 'Ehe' for?"
"…Nothing?" She tilted her head, putting on a clearly fake look of innocence.
"...Yeah, I'm heading back inside—"
"I've decided!" Nejire cut in.
"Decided what?" To get a job?
"Let's be heroes!" she declared, flashing a confident grin.
"...Heroes?"
"Mhm!" Nejire was already bouncing on her heels, clearly excited.
"...Why?" Isshun tilted his head in actual confusion.
At one point, Isshun had entertained the idea of becoming a hero. Being reincarnated into a world literally called My Hero Academia made that train of thought almost unavoidable. But in reality, heroes had always felt distant to him.
In the six years of life he'd experienced so far, his interactions with heroes and villains had been limited almost entirely to television.
While the classification he was born with was the Middle Class Average Family, with both parents having jobs, meant that their income bracket was technically in the middle high class of society.
This meant that the living conditions weren't near any crime heavy areas.
And with Isshun being a homebody, plus parents who neither idolized heroes nor placed much importance on them, heroes existed in his life only as a concept.
From his perspective, they were essentially just a more marketable version of the police.
"…Why, you ask?" Nejire froze.
That question had caught her completely off guard.
For someone as naturally curious as Nejire, it wasn't strange that a job involving flashy Quirks, dangerous situations, and meeting tons of interesting people appealed to her. It was like asking a kid if they wanted to be famous.
Most kids would answer yes without hesitation.
But knowing Isshun for the past year, she could already imagine the look he'd give her, like she was some kind of idiot.
And that annoyed her.
She wanted to erase that image he had of her!
She was his senpai, after all!
Yet for an entire year now, he hadn't shown her even a shred of the respect an elder deserved. Every kouhai at her elementary school respected her(even if she was only in second grade)! Even her parents sometimes mistook Shun-chan for the older one when they played together!
Look at the height difference! Look!
She was a full-fledged second grader, thank you very much! Shun-chan wasn't even in elementary school yet!
…Why is she looking at me like that?
Isshun watched as Nejire's face slowly twisted into a pout, her thoughts clearly spiraling out of control.
"Shun-chan!"
"Yeah?"
"I want to become a hero to save everyone!"
She definitely copied that straight from All Might. One hundred percent.
Still, Isshun hadn't asked the question to be philosophical. They were kids after all, and kids were supposed to have fun, not plan out their entire futures before they even learned what a job application was.
What was the point of worrying about adulthood now?
They practically had their whole lives ahead of them.
Really, he'd just wanted to see if Nejire would try to sound thoughtful. With her hyperactive, almost paramecium-like personality, even a clumsy excuse would mean she'd put some thought into it.
But kids were whimsical by nature.
Wasn't there a saying that mature children were the most heartbreaking, or something like that?
"Wow, Nejire," Isshun said flatly, "I didn't know you could even think that far ahead."
"Thanks!"
"...So, what do we do to become heroes?"
"...Well, I heard they have to go to U.A.! Just like All Might!"
"Do they?"
"Yeah!"
"So how do we get into U.A.?"
"How do we get into U.A.?"
"Now why in the world are you the one asking the question?"

A/N: It's surprisingly hard to try and get nejire's personality down without it sounding really overbearing or annoying, so i hope i did her justice.
Additionally, in my attempt to try to make her personality decent, i was thinking of Kiana Kaslana while writing this, lol.
