Izuku Midoriya did not have a soulmate.
Soulmates were much like quirks, temperamental and appearing usually in one’s youth.
At the dawn of quirks, soulmates became prevalent. Marks that would appear one one’s skin either at birth or at a seemingly random moment of time. Eventually, scientists discovered that the bond - or mark - would only appear when the youngest of a pair was born.
Not everyone would get a mark.
Much like quirks.
Quirks were in fact a different phenomenon, most people believed that the first quirk came from a glowing baby born in a small time Shanghai hospital.
Most people were wrong.
The first quirk came from a baby, born deprived of oxygen, yet miraculously living less than a second later. A recovery time so fast that no doctor noticed it.
Izuku Midoriya noticed his lack of aging at 30, when purchasing drinks at a bar, his ID confiscated by the police for being a ‘rather accurate false’.
Another 30 years later, Izuku still resembled his 16 year old self, sitting tiredly next to a screaming baby at 60 years of age.
He was so very tired.
So the next morning at 5:30 he wrote a note, tied it to his son's foot, and left him on the doorstep to Japan's best orphanage. Mourning the mother that could have lived a happy life with her wonderful son.
…
Kouse Midoriya lived a long and happy life, every now and then he thought of the parents that left him, but thought it was for the best, else he wouldn’t have his 3 grandchildren giggling around him as he read them a bedtime story.
…
When Izuku Midoriya turned 347, he still resembled a fresh-faced high schooler, and did not have a soulmate.
He mourned the day that one would appear.
…
U.A. High.
The worlds most prestigious hero school.
Run by the world's smartest creature.
Had a dilemma.
Nezu had wanted to go through the school's 300 year extensive history, cataloging every student to have ever roamed the halls.
When he spotted something mysterious.
A certain Izuku Midoriya, born July 15th, quirkless, had attended the school six times.
Each time he went through a different course.
The first was the hero course, back when it was more accessible to the quirkless society. Back when they were the majority.
The second was the support course. Then business, and so on.
If Nezu’s calculations were correct, in the next 17 years, Izuku Midoriya would be coming back, for either general education or the hero course.
Of course he would.
The boy, no man, had to be immortal.
…
It was that time of life again.
Izuku tapped at his computer, looking for a new place to live.
Hosu? No, it was too popular.
Tokyo? No, same issue.
Eventually he came across a small town called Mustafasu, and didn’t that bring back memories.
The apartment he found was plain and simple, cheep enough that the owner did not seem like the type to pry, despite his apparent age.
With one click it was his.
It should work for the next 20 years.
All at once a searing pain overtook his left shoulder, crippling him and causing his to cry out in agony.
Izuku fell to the floor, unfamiliar with the sensation of a soulmate bond snapping into certain place. It ripped at his skin, pulling it up and apart before sticking it back together with burning glue.
Time passed like a racing snail.
How long he spent sat on the floor was unknown, only it was dark when he finally felt at ease enough to move.
The trickling sensation of dread crawled down his spine.
He raced to the bathroom, tearing off his shirt as he stared in horror at the black infinity symbol that creeped over his shoulder.
No.
His soulmate had just been born.
…
Katsuki Bakugo fucking loved his soul mate mark.
…
Fifteen long years later, Izuku found himself staring up at the tall gates of U.A. high school once again.
Once again he used his real name, hoping that finally someone would notice the same person coming back every 50 years.
The hero at the gate took his entrance from and gave it a cursory glance. Expecting it to be as usual, he waited patiently for his little plastic card.
What he didn’t expect, however, was for the hero to go pale, looking between the paper in his hands and Izuku himself. “Hey kid, you’re not Izuku Midoriya, quirkless, are you?”
Midoriya’s eyes snapped up, meeting the blond haired hero's eyes dead on. “Will that be an issue?” The last thing he wanted to do was have another fight about quirkless laws.
“Not at all!” The hero flushed, his voice teatering on the edge of activating his quirk as he waived away the allegations. “Just, if any of us saw you, we were encouraged to send you to the principals office.”
Izuku grinned. Finally.
The hero looked slightly unnerved, but offered to help nonetheless. “Do you want me to take you there?”
“No,” He shook his head. “I know the way.”
…
Katsuki Bakugo grinned as he blasted through a group of robots with reckless abandon.
He was fucking acing this exam.
…
The rodent sat in his chair with nervous excitement as he did each year, waiting for the resident immortal to show.
Each year there was a close call, a miscommunication, a stray wandering sent his way.
He hoped this year would be different.
The person that knocked on the door fit the profile, if not a little timid.
Nezu ushered him to a seat, a game of chess set out on the table.
“Now, dear Midoriya, we have much to talk about.”
The apparent 15-year-old took a seat opposite the rodent, setting his bag down beside him. “What did you want to talk about?” he looked slightly nervous, not at all what he thought the immortal would look like. But it was undeniable, the only difference between him and the photo that had been submitted 50 years ago was the hair cut, no longer slicked back from, his face, but bushy and fluffed up.
“Well, for starters, how old are you actually, and what do you intend to do in this school.”
The green haired boy laid back, eyes crinkling; suddenly he seemed older, aged. The immortal sat there to think for a second pondering his words. “This time, I think I’m going to go for a hero licence again.”
“How many do you have?” A thought that had been playing on the rodents mind when he had found 3 under the same hero name of Deriku.
“Eight,” And wasn’t that an impressive number. “I started collecting them when I moved around to different countries.” He closed his eyes. “Physically, I am 16, have been since I was actually 16 and will probably be forever. Mentally, actually, legally, whatever you want to call it, I am 362.”
Nezu whistled at the number. “I believe you outdate even our exclusive school.”
“With all due respect, sir, I may have inspired it. There was a stint where I went around as a vigilante, I’d just abandoned my son and was feeling rather unbalanced.”
“Interesting.” Nezu leaned forward on his elbows. “Feel free to ignore it if this question is too sensitive, but what of your soulmate?”
“Should have just turned 15.” No one missed the sorrow in his eyes.
“Ah I’m sorry then.” And the rodent did actually look remorseful.
“Don’t be. I only hope to never meet them.”
“And why’s that?”
“Because I don’t want to watch them die again. I used to love someone, she gave me my son. But when she aged and I didn’t, she left us.” The green haired immortal sighed, a look of longing crossing his face. “I had to watch her die, still loving her. I never want to go through that again.”
…
It was clear to say that as fate intended, Bakugo Katsuki and Izuku Midoriya would be in class 1A together.
Despite the latter's wishes, the soulmates would meet.
…
Wondering through the halls of U.A. once again, Izuku noticed the small changes. The taller doors to accommodate mutant type quirks, the increased cameras, the unsealed vent entrances.
It was nostalgic.
Before he knew it, Izuku was standing in front of the door to 1A.
His admission into the school was easy, and he was glad that it had been so quick, a couple of keyboard taps and a cup of tea later, and Izuku Midoriya- quirk: Longevity, was enrolled.
They had decided on the name ‘Longevity’ as a nod to his immortality.
From the other side of the door he could hear yelling, so with a deep breath, he pushed it open.
Immediately the words became clear. “You need to remove your feet from the table! It is a disgrace!”
“Fuck off, your not my mother!”
“Your language is appalling!”
The two bickered back and forth for a moment as Izuku looked on. Growing bored of watching their spat, he glanced around the classroom, noticing a searing chart on the board, where he was placed behind the blond - Bakugo.
With a resigned sigh, he made his way over and settled into the seat. Head on the desk.
“Hey you!” He ignored the call, reckoning that it was meant for someone else. “You with the green hair!” Maybe there was someone else who had green hair.
Someone tapped on his desk.
Izuku raised his head up and looked at the blue haired boy with a raised eyebrow. Said boy chopped his arms wildly, punctuating his words with each action. “You must not sleep while in school! It is also disrespectful!”
Izuku sighed. “Why don’t you go back to annoying the blond.” The blond in front of him snorted.
“What is your name? I did not see you at the entrance exam. Are you sure you are meant to be here.”
“I’m as meant to be here as you are.” He dropped his head back into his arms. “Now please leave me alone.”
…
The rest of the day was interesting, since attending last, the protocol for every student to attend orientation had obviously been dropped - the fact that his class did not attend, attested to that fact. At the Quirk assessment test, Izuku remained relatively in the middle of the pack. Despite getting called out for not using his quirk, he found he quite liked this teacher.
“Midoriya!” Aizawa barked, eyes flashing. Oh and wasn't that strange, having his quirk erased. Did he just age? For a second? Was he one second older? Not nearly enough to notice. “Why haven’t you used your quirk.”
“Can’t do sir.” He responded, already wondering if the teacher had read the files of each student.
Aizawa took a breath. “And why’s that?”
“Because I don’t think being able to live longer will help me here.”
“Fair enough.” The teacher closed his eyes, and the red glow dimmed.
Of course that wasn’t the full extent of his quirk. Anything that tried to kill him would fail.
Even old age.
Especially old age.
…
Izuku sat in the classroom, head on the desk again as he waited for the new heroics teacher to join them.
“I AM HERE, COMING THROUGH THE DOOR LIKE A NORMAL PERSON!”
His head stayed down until they filtered out the classroom with their uniforms (he would refuse to call them costumes).
The changing rooms were busy, with the boys showing each other their soulmate h=marks. He stepped into a cubicle, not wanting to risk exposing his own, especially as his soulmate was around this age.
Changed and with the exercise explained, Izuku walked over to his partner, Uraraka.
He stuck out his hand for a handshake, “Izuku Midoriya, my quirk is longevity.”
She accepted it. “Ochako Uraraka, my quirk is zero gravity.”
…
Crouched behind a pillar, Katsuki grinned when he saw the broccoli one round the corner.
He was cool, Katsuki thought, unlike the other fucking extras that annoyed him. He was also the only one to talk back to that Robo mother fucker when he was also being a pain in the ass.
For some reason, Bakugo had found his gaze attracted to this boy all day, from when he snapped a Iida, talked back to hobo sensei and went into a changing cubicle.
It was strange, but it led to Katsuki seeking a fight out with him during the battle.
Watching from behind the pillar, he realised that he had been staring too long.
With a burst of his quirk he shot forward. “FUCKING FIGHT ME!”
His bare fist collided with Broccilies bare face…
The world exploded into white light.
…
Shit.
