Based on a prompt suggested by The Mad Mystic. Hope you like it!
Hisashi Midoriya liked to think he was a good father.
He made plenty of money for his family, ensured his wife didn't have to work a single day in her life and looked after his son whenever he wasn't killing heroes on the down low.
Little Izuku also happened to be turning 4, meaning he'd soon manifest a quirk! He could hardly wait to see his mini-me running around fulfilling his dreams.
Sure, the kid wanted to be a hero, but he didn't mind. It was a parent's job to unconditionally support their child, of course, and if his son wanted to be the next Number 1 Hero, he'd be with him every step of the way.
Unfortunately, there was a massive thorn wedged in that plan.
All Might. The most ridiculously overpowered wielder of One For All to date.
If his son wanted to become the next number 1 hero, Hisashi would have to remove the man himself. There was no way anybody could surpass him with that monstrous strength of his.
Thankfully, he had the perfect solution. An art he'd honed for generations.
He'd have to kill the user of One For All.
As it turned out, Hisashi may have underestimated the man a little.
He knew the man was strong, but he didn't factor in his absurd speed. He was embarrassed to admit he started off the fight being tossed around like a pinball, and while his slew of durability quirks kept him alive, no man could tank hundreds of city levelling punches without a scratch.
Luckily he managed to compose himself and pump his speed quirks up, allowing him to begin matching the hero blow for blow.
"I'm going to make you pay, All For One!"
Couldn't Mr Justice Boner just kick the bucket already? Izuku was getting his quirk results, and Hisashi was already mad that he couldn't be there to witness it first hand.
"You know, I've heard those exact words from 7 other people before you, and the outcome won't changed a bit." He taunted. "It sure would be nice if your master were here threatening me though. She looked a lot cuter trying to intimidated me than the roid pumping maniac I'm stuck fighting."
Hisashi dodged the punch aimed for his head, weaving between the subsequent strikes.
Good - he got the idiot riled up. He could already see his fighting becoming sloppy, with small openings presenting themselves.
Calf? Too high of a chance of dodging.
Shoulder? No, not fatal enough.
Stomach? Bullseye.
Coating his hand in as many piercing quirks as possible, he dug his hand through the hero's gut, revealing his fist through the other side.
"How pathetic." Hisashi mocked, pulling his hand out and letting the hero slump to the floor. "7 generations of pure mediocrity. To think my brother's quirk would be put to waste like this."
Hearing his phone chime, he pulled it out to find a text from his wife.
Inko: Dear, the Doctor said Izuku was quirkless.
…son of a bitch.
He was half hoping his son would inherit All For One, but he supposed this outcome wasn't impossible. As a first generation quirk user, the odds of having a quirked child were lower than they were with most families.
That wasn't a massive problem though. He had plenty of quirks stockpiled, and Izuku was immensely bright. The little tyke could probably make it to the Number 1 spot with a hair-colour changing quirk if he put his mind to it.
His thoughts were interrupted by a brutal smash to the face.
It seemed he really did underestimate that yankee. Checking a text without confirming an enemy was actually dead was a bit of an idiotic move on his part. He was lucky to have made it out of the fight lightly injured.
In Hisashi's case, 'lightly injured' was getting his head caved in to an extent where the regeneration quirks he stockpiled couldn't heal him completely.
It was no matter though. He managed to gouge out the bastard's stomach, and even if All Might survived he wouldn't be in any condition to be half as effective as he was in his prime. Meanwhile, Hisashi could just find a quirk to reverse the effects of this injury. Cell activation or something similar would do the trick.
Wait.
Quirks.
Izuku was quirkless. He almost forgot.
"Kyudai." Hisashi shouted from his hospital bed, sensing the doctor's approach with infrared vision. "Izuku's completely powerless, right?"
"My Lord, you're awake?"
Was the old fool getting senile? Of course he was awake! He was the symbol of evil for God's sake. A small fight with a juiced up gorilla wouldn't keep him down for long.
"Yes. Now answer my question."
"Yes, my Lord, he's been quirkless for a good decade now."
…what?
"Has my hearing been damaged along with my sight, or did you simply misspeak?"
"N-neither, my Lord! I'm afraid you've been in a coma for a little over 10 years."
Oh.
Oh fuck this was bad.
10 years was a long fucking time, and a lot could've taken place in the world to royally fuck him over.
If that baboon survived the stomach injury, One For All could've been passed onto yet another user. That was among the more dangerous of his problems.
As if that wasn't bad enough, there was also the matter of his family.
"What happened to Inko and Izuku?"
"There's no need to fret." The doctor placated. "Upon finding you injured in your battle, I took the liberty of finding a man with a shape shifting quirk to tell your wife you'd be working in America. I've been sending adequate funds to your family in your stead to keep up the ruse."
If Hisashi were a lesser man, he would've kissed this old cretin.
"You have my gratitude, Kyudai. Your loyalty shall not be forgotten."
Then another thought occurred to him.
Izuku was around 14 years old, meaning he grew up quirkless.
"Kyudai, how long until I'm able to move?"
"You should be able to now, my Lord, though I'd suggest sticking to air walk for now. I did my best to ensure your muscles didn't atrophy but you might encounter a little stiffness for a few days." The doctor explained. "You would also require a respirator."
"Perfect. How long would it take to make?"
"A day at most, my Lord. Do you have any design specifications?"
"I want black."
"Of course, my Lord—"
"With something to deepen my voice."
"Yes, my Lo—"
"I suppose some silver on the wiring would be cool too."
"Understood, my—"
"A cape would also—"
"Jesus Christ, shut the fuck up!" The old man finally snapped. "I've been looking after your weak body for a decade. I've had to ensure that shitty brat Tomura was taken care of and uphold your criminal empire while simultaneously wiping your ass and trying to get you to wake up! Would it kill you to show a little restraint? Making you a Vader costume after acting as your maid for 10 years is the definition of insanity!"
"…"
"…I deeply apologise."
"No need. I can tell you've been under a lot of stress lately. I can excuse a minor outburst."
"…"
"You're free to leave out the cape, but the rest stays."
"Yes, my Lord. Thank you, my Lord."
"And send in Tomura while you're working on that respirator. A little entertainment would do me some good."
"Sensei! You're alive!"
Hisashi felt a weight press down on his torso with many of the boy's dismembered hands jutting into him.
Why did he ever think taking this kid in would be a good idea?
"Tomura my boy, I'd appreciate it if you eased up on your grip. I'm in unspeakable pain."
"Right! Sorry Sensei!" Tomura swiftly released him. "I haven't seen you in years. What happened? Who could do this to you?"
"All Might."
"I'm gonna turn him to dust." Tomura seethed, scratching at his neck. "This phony goes on about his goals for peace, but he does this to a kind man like you, Sensei? I can't believe his nerve!"
Ah. Now he remembered why he took the kid in. He thought it'd be a good idea to turn the seventh's descendent psychotic, and as shown by the boy's demeanour, it somehow worked.
Unfortunately, judging from the boy's language, All Might was still alive and kicking. On the bright side, if he was still active hero, he was still carrying One For All, meaning he didn't have to worry about getting his ass kicked by another wielder of the power.
"Thank you, my boy."
As soon as he got that sweet mask, he'd kill the justice loving dolt, heal completely, return to his family and bestow a quirk upon Izuku.
Hell, his boy grew up quirkless, so he might even consider coughing up All For One as a little retribution.
Locating All Might wasn't difficult in the slightest. One For All was a beacon of energy, and through his multitude of sensing quirks, locating the source was light work.
What he wasn't prepared for was finding his son with the man cleaning up trash.
He wished he could actually see as opposed to using infrared vision. Though from what he could infer, Izuku was the spitting image of him at his age. A little shorter than most 14 year olds, but he'd undoubtedly hit an immense growth spurt just as Hisashi had. His hair retained the messy curls from when he was a child, though they were longer than his own. He also seemed a little on the scrawny side, not unlike Hisashi's late younger brother, but he could tell there was some muscle growing.
Why the fuck was he here with All Might? He couldn't nuke the bastard with quirks if he had his son as meat shield!
Flaring up a superhearing, he managed to listen into their conversation.
"—ome on, Young Midoriya! You can't inherit One For All if you don't get this beach cleaned!
…eh?
"Yes sir!" Izuku grunted, hauling a refrigerator.
Hisashi was, for the first time in a good century, stunned.
The likelihood of this happening was astronomically low, yet his son was going to inherit One For All.
…he supposed letting All Might live a little longer wouldn't hurt. At least until his boy managed to master the quirk.
One For All was certainly a much better ability than any in his arsenal, and this would mean he could keep All For One while his son had an equally busted superpower.
This left him with another dilemma - what was he supposed to get his son to makeup for his absence?
The gorilla already basically ensured Izuku would reach the number 1 spot, so the least Hisashi could do was kill off any competition.
He also couldn't give the boy another quirk as a present; he saw the effects of multiple quirks on humans, and unless he wanted his son to end up as brain dead as those Nomu experiments from a few years back, that option was firmly off the table.
He needed a second opinion on this. Kurogiri had a good amount of common sense, so he supposed confiding in him wasn't a bad idea.
Teleporting over to the shadowy butler, Hisashi found himself at a bar counter.
"Good day, sir?"
"More like confusing." He sighed, slumping in a barstool. "I've been wondering what I should get for…someone to make up for my absence in their life."
"Oh? Might I suggest some brandy?"
"They're 15."
"Wine?"
This was a mistake.
Warping out of the bar, he found himself back at one of his many mansions.
Could he simply pawn off his assets on him? He owned a fair amount of Japan, so that might be a decent plan.
…
No, that was far too cheap. He'd gladly gift Izuku the world, but he wanted to give him something with a little sentiment.
As he was aimlessly pacing around the house, he accidentally bumped into a table, knocking over the contents. Bending over to pick up his belongings, he felt something he hadn't read in years.
'Life of the Greatest Hero.' His little brother's favourite comic as they were growing up.
From what he recalled about the story, the hero was a powerless boy who eventually awakened an incredible power, rising to the world's primary protector while absentmindedly collecting a slew of lovers.
Hang on, that was it!
This story was exactly what he needed!
His son was the perfect embodiment of this tale, and the only thing he was missing was the harem of girls! He couldn't be there to help awaken his power, but Hisashi was damn sure he'd do everything in his power to make this harem a reality.
A few months passed and he finally completed his plan. Between festering Tomura's hate for All Might, creating a bunch of Nomus and finding a quirk to reverse his injuries, Hisashi was completely tuckered out, but it was all worth it in the end.
Today was Izuku's entrance exam, and therefore the beginning of 'Hisashi's Master Plan'.
Arriving at the entrance exam, he saw his son waiting at the gate with a determined look on his face.
"Move aside, Deku!"
Katsuki Bakugo. Quirk: Explosion.
"Kacchan!" Izuku exclaimed.
"Get out of my way, or you're dead."
Izuku rambled hurried well-wishes as the blond pushed past him.
Ah. So this was the little terrorist in his natural habitat.
He managed to get a clear picture on how the foul child treated his son over the years after some digging into Aldera Junior High.
Katsuki held a very special place in his master plan. In the meantime, he had to focus on the more central parts.
Following some extensive analysis of the prospective students, he was able to compile a list of the female students most likely to make it into the hero course. And right now, one of them was near Izuku.
Ochako Uraraka. Quirk: Zero Gravity.
He had the perfect opportunity to make their paths cross.
Just as Izuku was about to take a step, Hisashi used a terrakinetic quirk to lift a brick off the earth, catching his son's feet and causing him to trip.
Before the boy started eating dirt, Ochako floated him.
Just according to Keikaku.
The chessboard was set. All Izuku had to do was successfully woo this girl and Hisashi could move onto whoever was next.
Except Izuku wasn't saying a thing.
He just stood there gawking as the cheery girl wished him luck before heading off to the entrance exam.
God fucking dammit.
So it seemed his son didn't inherit his skill at charming women. This made his job infinitely more difficult.
Hisashi decided he might as well observe the practical exam using a cloaking quirk while he lamented his anguish.
Currently, Izuku was running around without gaining a single point. He wasn't all too concerned for his boy though. Through the boundless power of nepotism, he had no doubt All Might would pull some strings and get the boy into the school, even if he ended up without a single point.
He had much larger issues on his mind. Namely Izuku's crippling ineptitude when it came to the opposite gender.
Could he pull an Endeavour and simply buy off the girl? The Urarakas were relatively poor, and he could probably pay the parents to gently nudge their daughter towards his son.
…
No, that wouldn't do. The point of this harem plan was that Izuku had to woo them himself. Hisashi's job was to lightly push the girls in his direction.
He was broken out of his thoughts by the ground quaking beneath his feet.
Holy shit.
Was that a fucking gundam? That insane rodent couldn't possibly think mere children could take it down.
Looking towards the robot's path, he found something that made his blood run cold.
The Uraraka girl was trapped and in its line of sight.
This was very bad.
He needed her alive for the harem.
For Christ's sake, he had everything planned. She'd be inspired by his noble heart, throw herself at him and give him plenty of grandchildren in a few years. Hell, even if the harem didn't work, he would've wanted her as a daughter in law. She seemed outrageously kind; a lot like Inko in that sense.
Oh well. Time to use an electrokinetic quirk and take it down discretely. With any luck, UA would blame it on shoddy construction on Power Loader's part.
Just as he stood up, he saw his son zip through the air, finding himself at the robot's head.
Holy fucking shit.
This fucking kid.
He watched in awe as Izuku pulverised the robot in a single punch.
All to save the girl.
The ship sails!
He knew his boy must have inherited some of his talent with the ladies, but he didn't think he would be this smooth! This was some classic damsel in distress shit, meaning Ochako would naturally be enamoured with him.
Now all Izuku had to do was make sure he didn't die from the fall.
"Sensei, I want a Nomu."
"Put it on your Christmas list." Hisashi absentmindedly replied, tinkering with his plans.
He had to rewrite his original concept based on Izuku's way of wooing women.
Initially, the plan consisted of Izuku charming the girls with unwavering confidence and sweet compliments. He evidently wasn't built like that, as demonstrated by his first interaction with Ochako.
Luckily Izuku's 'hero saving the day' type of wooing worked just as well, if not better! He even caught sight of Izuku walking to the train station with Ochako after school a few times whenever the Iida boy was chauffeured.
At the moment though, he was a little stumped; he couldn't think of ways to put Izuku in a heroic light.
Sure - he could wait until he became the number 1 hero, but that would take far too long. There was also the possibility the girls in the plan would hook up with other guys in his class, meaning the harem would consist of regular civilian gold diggers, and he couldn't let that happen.
"Sensei, please! I wanna attack UA and kill All Might!"
For heavens sake! Couldn't Tomura see he was extremely busy—
Wait.
Tomura wanted to attack UA.
Meaning Izuku would find himself in another disaster situation.
Meaning another girl could find her way into his harem.
Meaning the almighty keikaku was back in action.
"Tomura! You're a fucking genius!" Hisashi exclaimed, jumping out of his seat and slamming his hands on the desk.
"Eep!" Tomura couldn't help but squeak at the change in tone before composing himself. "I mean, thank you Sensei! I'll be sure to kill All Might for you."
"That's my boy." He ruffled his hair affectionately. "You're free to use Highend-C for the task."
"Thank you Sensei." He bowed gratefully. "I'll take care good care of Gerald - he'll be perfect for the job."
"…Who?"
"Nothing." He hastily retracted, before coming to a realisation. "Uhh, Sensei, if you're already healed, why do you still wear that respirator?"
"Because it's badass. Now run along and start recruiting for this attack on UA."
Hisashi sat back down and pulled out his phone once Tomura left.
Vader: Kurogiri.
Misty: Sir?
Vader: Tomura's planning an attack on UA. I'd like you to ensure Izuku Midoriya is paired with Tsuyu Asui. Make sure they're in a situation for the boy to show off a little. And don't let either of them die either.
Misty: Yes sir.
Vader: Perfect! I'll be sure to procure some quality wine as your reward.
Misty: Could I have permission to change my screen name instead, Sir? It sounds alarmingly feminine.
Vader: No. You get wine.
Misty: Yes sir.
"Sensei! It's not fair! That damn phony killed Gerald."
"A necessary sacrifice my boy." Hisashi patted his head. "I'm certain he's in a better place."
Hisashi watched the boy leave to sulk over video games, turning to face Kurogiri.
"How did Izuku perform?"
"From what I could observe, he rescued Tsuyu Asui, as well as a fellow classmate."
"Oh? Another female?"
"No, sir. He was male."
"Ah - a shame. A two for one would've been nice, but beggars can't be choosers." Hisashi sighed, reaching under his desk and holding out a bottle. "In any case, you successfully completed your task. Take this as a token of my gratitude."
"Thank you sir." Kurogiri snatched the bottle before swiftly warping away.
He couldn't blame him. Being forced to babysit Tomura could drive a priest to alcoholism.
Hisashi silently seethed as he watched the sports festival take place.
He hadn't found a single opportunity over the past two weeks through which he could expand Izuku's harem and it was beginning to fray his nerves.
He thought he might've had a free pass with the sports festival, but as it turned out, the first event was a simple race. How the hell was Izuku meant to woo anyone without the chance to save people? This was meant to be a hero school for God's sake!
His mood further deteriorated watching his son forced to do the race essentially quirkless.
Did All Might actually teach Izuku anything?
He could excuse bone breaking for the first 2 or 3 attempts at using the quirk, but this was ridiculous! It'd been a good 2 months since he received One For All and Izuku was still hurting himself. If this situation didn't rectify itself soon, he might have to step in and teach him himself.
Just as he was ready to turn away from the screen in annoyance, he caught sight of an explosion at the minefield, with a flying object soaring through the air towards the finish line.
Wait.
That was Izuku!
Who needs powers? His son was good enough to come first completely quirkless!
Hisashi couldn't help but cheer audibly as the boy emerged out of the tunnel to meet the roaring crowd.
"Uhh…Sensei? Are you alright?"
Oh. He forgot he was in the bar with Kurogiri and Tomura.
"Ahem." He cleared his throat. "Excuse me, I got a little wrapped up in the competitive spirit."
"In which case, sir, would you like to make a bet?"
"Oho?" Hisashi enquired. "Are you drunk, my friend, or have you forgotten the outcome of our last bet?"
The mist man thought it was impossible to give insects quirks. Since then, he had to deal with a warping spider dropping in on his bar at random intervals, in addition to losing a treasured bottle of 50 year old wine.
Needless to say, Kurogiri was a broken man for a good 2 months.
"The outcome is still very fresh in my mind. If you would pardon my language sir, I would like this opportunity to kick your ass and get my alcohol back."
"And if I win?"
"I'll babysit Tomura for a month straight without pay."
"Hey!" The manchild whined from the seat.
"You have yourself a wager." Hisashi shook the man's hand. "What are we betting on?"
"The final tournament round for the Sports Festival." Kurogiri stated. "I bet Endeavour's boy will take first place."
Oh this situation was golden for Hisashi.
At first, he was worried by Kurogiri taking the first pick, but for some reason, the dunce wanted to chose second place from the race?
Ignorant fool.
"I place my bets on Izuku Midoriya."
"Wha—Sensei! But he's the All Might brat!"
Hisashi had to refrain from crushing the boy's head.
"Not all strength enhancers are like All Might my boy." He chided. "If anything, I'd liken the boy more to myself."
"Huh…I suppose I can see some resemblance." Tomura squinted at the picture of Izuku resting in his palm. "If I didn't know any better, I'd almost think you're relat—"
"Anyway!" Hisashi hurriedly changed the subject. "Tomura, don't you think it'd be fun to get in on the betting?"
"Oh, sure!" The boy perked up. "I want 3 Nomus if the one with sparks takes first place."
Hisashi simply glanced to the side, sharing a look with Kurogiri before the pair burst into uproarious laughter.
"Oh—ha, oh my—I didn't think you had a sense of humour, Tomura Shigaraki." Kurogiri huffed out between chuckles. "The brat looked thoroughly unhinged during the USJ attack. A hero school wouldn't put him as their forerunner if their lives depended on it."
"But that's exactly what hero society is all about! Mindless destruction for the sake of—"
"Alright, alright." Hisashi cut in before Tomura could go on his tirade. "Tell you what - since you're making such an outlandish bet, we won't even demand anything in return."
He abruptly warped out of the bar following the statement. After all - he wasn't going to miss the chance to see his son wipe the floor with the competition.
This sports festival sucked an unbelievable amount of ass.
Hisashi was sure he would've fallen asleep if not for the Todoroki boy's giant ice wave jolting him back into consciousness. Thus far, that was the only semi-interesting development among the students.
The cavalry battle was straight bullshit. He was thoroughly impressed that Izuku managed to even make it through to the final round with a bullseye painted on his back.
Then came the 1v1s, which were stale enough to send an insomniac to sleep.
He expected a hell of a lot more from that Yaoyorozu girl too. She easily had the most impressive quirk he'd seen in years - the only reason he hadn't pilfered it already was because she'd make an excellent addition to Izuku's harem.
Smart? Strong? Confident?
He couldn't detect a hint of those qualities in the match!
Standing up to sulk momentarily, Hisashi made his way through the hallways, only to pick up the faint sound of sniffling. Activating X-Ray vision, he could see the raven-haired girl sobbing on a staircase. In his peripheral, he could also spot his son walking from what he presumed to be the infirmary.
There was no way in hell he was going to miss this opportunity.
Flaring up terrakinesis, he gradually shifted the hallways to create a straight path for Izuku to reach Momo. Hisashi found himself incredibly lucky: had the boy not been muttering up a storm, he undoubtedly would've noticed.
Hiding in the shadows, he observed the developments closely.
"…andifibeattodorokitooquicklythenhisfatherwill—wha, Yaoyorozu?" Izuku blinked, removing his hand from his chin as he broke out of his mumbling.
Momo snapped her head up, swiftly wiping away her tears before they were visible. "H-hello, Midoriya. What can I do for you?"
"Are you okay?"
"I guess there's no hiding it from you - you're rather observant after all." She relented with a weak smile on her lips. "I guess I'm feeling somewhat disheartened after my match."
"Oh." Izuku stood there, scratching his cheek awkwardly. "It wasn't a very impressive showing."
From his hiding place, Hisashi wanted to ram his own head through a wall.
"If I were in your position, I would've thrown out a flashbang."
"What for?" She tilted her head. "I don't see how… Dark Shadow's weakness is light!" Her face lit up in realisation. "During the cavalry battle, it started screeching when Kaminari unleashed his electricity! At first, I assumed it was simply due to the pain, but the concept of a quirk feeling physical damage from an electric is frankly absurd. Although, to counter that, sentient quirks are still a mystery to—"
Izuku simply listened in awe, wondering if this was how people saw him when he delved into the specifics of quirks.
Had he been more attentive to his surroundings, he would've heard a faint 'Just according to Keikaku'.
Hisashi felt infinitely more grateful that he came here. It almost made up for the utter mediocrity he was forced to spectate since arriving.
Until this fight, at least.
Izuku was facing the Todoroki brat, meaning he could both show off his boundless strength to the millions of women watching the event in addition to winning Hisashi some free babysitting.
So why the fuck wasn't Izuku winning?
He saw the boy break an unruly amount of appendages, and as much as it pained him to witness it, he likely would've done the same in his position. What Hisashi would've done differently was simply knock the brat out of the ring. Izuku had ample opportunity to win; everyone in the stadium could see it.
Except he was simply standing there shouting to him.
Firing up superhearing and blocking out the roars of the crowd, he got to the crux of the problem.
The boy was too damn heroic.
Apparently, where Hisashi used speech to degrade and demoralise his opponents, Izuku inherited a mutated version of that trait where he could motivate them. It seemed pretty effective too, considering fire began bursting out of Shoto's side.
It was no matter though - Izuku still had this. He managed to jump above an ice wall, and was winding back his arm to counter a wall of flames when—
Motherfuckers.
They interrupted the fight! What kind of bullshit match fixing was taking place here?
Sure, the kids would've been severely injured, but there was no way in hell the Todoroki boy would've stayed in the ring without the intervention.
UA just cost him a good bottle of alcohol, and he'd make sure they pay for it in due time. Likely with the Bakugo brat taking the brunt of the damage.
Hisashi was absentmindedly spinning his pen, contemplating where it all went wrong.
Wait. He knew exactly where it went wrong.
That fucking school festival.
For some reason, that godforsaken Todoroki brat threw his match against Bakugo, meaning Tomura got his wishes and received three nomus to do as he pleased with.
When he coughed up his end of the bargain, he half expected Tomura to use them for some weird sex shit. After all, the guy had serious issues.
Looking at the current situation, he supposed that outcome would've been much more preferable.
"Would you like to repeat yourself, Tomura?"
"I said that this is all Stain's fault! If he didn't stab that Nomu, we would've got our hands on Izuku Midoriya."
Hisashi banged his head on the desk.
He despised owing debts - now he'd have to sneak a box of chocolates through Tartarus's security for the hero killer.
"I tried to warn him, sir." Kurogiri attempted to save his own neck. "You've made it explicitly clear that Izuku Midoriya was to be spared, and while I'm unaware of your reasoning, I am still doing my best to enforce that order."
"I suppose it's time you know the truth." Hisashi relented. If they didn't agree with it, he could always kill them and find replacements.
"Izuku is my son."
Kurogiri audibly choked on his spit while Tomura accidentally decayed the arm of his chair.
"That would certainly explain a lot." Kurogiri murmured before straightening up. "But in that case, sir, what was the point in the USJ incident with Tsuyu Asui?"
Hisashi stood in his seat, removing his mask and sternly staring at his subordinates.
"Simple: it's for the keikaku."
As it turned out, his two pawns took to the plan with much more enthusiasm than he anticipated.
Between Kurogiri's unwavering loyalty and Tomura's blind adoration for him, Hisashi found himself with two followers in his plan.
While Tomura was busy gathering allies for the league, Hisashi decided to hurry his plans along.
Namely by stalking his son's class during a visit to the mall.
Between Ochako, Tsuyu and Momo, he was at 3/6, and while he was undoubtedly ahead of schedule thanks to the coincidence with the rich girl, there was no such thing as being too ahead of schedule.
Although waiting until the target was in a desirable position was beginning to wear on his nerves.
Spotting the chance to strike, he fired up his new favourite quirk: terrakinesis.
It was too damn useful for these situations.
Hisashi watched as Toru Hagakure tripped, spilling her milkshake on Izuku's shirt when the boy instinctively reached out to straighten her up.
"Oh shit, sorry Midoriya!" She hurriedly began wiping at his shirt with a napkin, before dragging him away. "It's no use - the convenience store we passed should have some wet wipes."
"Oh—umm, thanks, Hagakure." Izuku stuttered through the unfamiliar feeling of his hand being held by a girl. "You really shouldn't worry though; it's just a shirt."
"No way! If I had been watching where I was going, none of this would've happened."
"It's more my fault, really! I tried to reach for you when I saw you trip. If I just moved more to the side, it probably would've missed."
"Wait." Toru stopped, turning to face Izuku. "You saw me trip?"
"Huh? Of course." He stated as if it were obvious. "Your clothes completely shifted, and the bracelet on your left hand flailed a little when you lost your footing, so it looked more like an accident than an incidental skip in your step."
"You…noticed the bracelet?" She looked to the side shyly as if trying to conceal her invisible blush. "I like using it to articulate my gestures more, but nobody really pays attention."
Smooth little bastard.
Hisashi's job here was done, and with a smile on his face, he warped back to the bar, removing his helmet and stroking a hand through his grey locks in satisfaction.
"Woah, who's the dilf?"
And there went his moment of peace.
Looking towards where the statement came from, he caught sight of a woman leaning on a wrapped up slab. Taking a glance around the rest of the bar, he saw some other ruffians he didn't expect to see—
Wait, was that fucking Muscular?
As much as he could appreciate a fellow villain, he didn't want anything to do with this aimless psycho.
Whipping his head to Tomura, he decided to get a clear picture of the situation before killing the blond brute.
"Sensei, I can explain."
"Oh, can you?" He narrowed his eyes.
"If you give me thirty seconds to think of a good lie."
Reaching a hand out, Hisashi gripped Muscular by the throat, raising him into the air.
"Wait! He's a recruit for the attack we're planning on UA!"
Oh for heaven's sake!
How many times did he have to tell Tomura not to—
Hold on. The last attack ended up with the frog girl in Izuku's harem.
Who knew what this one could bring?
"Tomura, I understand." He nodded sagely. "I'm incredibly proud of you."
"Thank you Sensei, but could you release Muscular? I think he's unconscious."
"Oh. Right."
Apparently, Tomura's plan was dogshit considering the only person Izuku saved was some little brat as opposed to one of the two remaining girls from his class.
It wasn't a huge loss in the grand scheme of things though. At the moment, he has to focus on the next biggest part of his plan, which was also the riskiest.
Changing his face with a shapeshifting quirk, Hisashi ensured he appeared as injured as he was when he awoke from his coma.
After all, for the plan to work, it had to look like All Might convincingly beat him, and there was no way in hell the cripple could beat him while he was as strong as ever.
Next came the more fun part: Katsuki Bakugo.
As the heroes burst into the bar, Hisashi warped in a few Nomus to serve as a distraction before brining the league members and explosive teen to him.
"Tomura, you must escape with the members of the league." Hisashi patted his head. "You are aware of your part in the plan, correct?"
"Yes Sensei - you can trust in me."
"Good boy. Remember: for the keikaku."
"For the keikaku." Tomura nodded resolutely.
"What the fuck…" Bakugo whispered in disbelief.
"Ah! Young Bakugo!" Hisashi absentmindedly used forcible quirk activation on Kurogiri, allowing the league to escape from the battlefield. "I've been wanting to meet you for a while." He slowly approached him while the boy was stunned in fear, placing a hand on his blond hair as he flinched at the contact. "I hope you enjoy your pitiful life." He leaned in towards his ear, whispering the next words. "You quirkless loser."
Hisashi ripped out his quirk before picking the boy up, throwing his unconscious body towards the direction All Might was flying in from.
The hero caught the teen before landing to face down his mortal enemy.
"I'll have you return everything you stole, All For One!"
Well - he planned to throw the fight anyway. He might as well have some fun while he was at it.
"You know, your predecessor Narnia—"
"Nana." He corrected behind gritted teeth.
"Yeah, that's the bitch. She said the exact same thing to me before I turned her into a blood stain." He gloated, holding out a hand towards All Might. "Let's see if I can do the same to you."
Prison sucked ass.
Hisashi didn't know how many more months he could keep up the facade of a weakened old man, but his patience was wearing thin.
Luckily, his prayers were answered as he felt the presence of the copy of his quirk.
He wasn't aware how Kyudai worked his magic scientific bullshit, but he was able to engineer a version of All For One with the ability to steal a fair amount of quirks, and while it paled in comparison to his own, it was still impressive.
It wasn't until a good few hours later when he felt the Tartarus walls collapse, revealing Tomura dragging an unconscious Gigantomachia in by the leg.
"It's been a while, Sensei."
"It's good to see you my boy." Hisashi flared up his quirks, effortlessly breaking out of his restraints and walking towards the duo as he reverted his face to his uninjured appearance. "How goes the plan?"
"Excellently Sensei. Our spies caught word that Izuku has progressed from friendships to relationships with the girls."
"Just as I expected." Hisashi chuckled. "Any developments regarding the last two members?"
"Our spy caught Mina Ashido teaching Izuku to dance during the preparation for the Cultural Festival. Since then, she's been a member of the harem."
"Perfect, and the Jiro girl?"
"Ah…there were some—umm, complications with that one." Tomura shifted his feet awkwardly. "She seems to be in a relationship with our spy, Denki Kaminari."
…son of a bitch.
There was no way he was letting some side character ruin his plans.
"I've been holding out on killing him, since we needed him to observe the school, but now the plan has advanced to this stage…" Tomura trailed off, allowing Hisashi to understand his train of thought.
"You've matured significantly." He complimented. "The old Tomura would've simply killed him without a second thought for the long term consequences."
"I had no choice but to grow, Sensei." Tomura stared him in the eye with intensity. "All for the keikaku."
Hisashi couldn't have been more proud of a boy who wasn't his own.
"I suppose you know what needs to be done now, then?" Hisashi inquired, receiving a nod in return.
Holding out his arm, Hisashi allowed Tomura to sever his arm at the shoulder using decay, allowing the limb to fall to the ground before doing the same with his other arm, followed by his legs.
Regenerating his lost appendages, Hisashi stood back up.
"This should make it look like you killed me before fleeing, meaning you'll be Izuku's sole target." He stated as he dusted off his hospital gown. "Also, the fuck happened to Machia?"
Tomura looked at the slumped beast before kicking him in the ribs.
"I told the idiot it'd be a good plan to bring Midnight for Izuku. After all, what man wouldn't want a hot dommy mommy in his harem?"
Hisashi nodded in agreement. "A wise decision, but how did that lead to this?"
"The oaf misinterpreted." Tomura shook his head in annoyance. "He didn't want anyone dominating his 'little Lord' so he squished her."
"Ah…a shame." Hisashi sighed, before having an epiphany. "If I recall correctly, Lady Nagant is locked up in this prison…"
Hisashi was lounging on his sofa, blissfully enjoying his retirement as he watched his son face off for the last time against his protege on TV.
He couldn't help but admire Tomura's drive - to show so much dedication to a plan that wasn't his own was incredible.
Noticing that his apprentice was running out of steam, he warped over to a location near the battlefield, observing as he was slammed into the ground with a final smash. Equipping a cloaking quirk, he snuck up next to Tomura as Izuku collapsed out of fatigue.
Apparently not confirming if the enemy was dead ran in the family.
However, once by Tomura's head and placing a hand on his skull, he could detect that the boy didn't have long left - the multitude of quirks in his body coupled with the damage sustained from the fight was too much.
"Sen…sei." Tomura wheezed, slowly opening his eyes. "Did we win?"
"Yes we did, my boy." Hisashi placated. "Truth be told, you've always been like a second son to me."
A peaceful smile rested on Tomura's face as he uttered his departing words.
"Just according to keikaku."
Hisashi warped home, his mind exhausted in spite of the multitude of quirks he had to lessen the need of sleep.
Not even bothering to change out of his suit, he slumped down in his bed, rethinking his life.
Sure, he had a lot of regrets.
The way he handled his brother would always weigh heavily on his mind, as well as the situation with Inko. As much as he would've loved to show back up on her doorstep, he wasn't foolish enough to believe everything would be back to normal. He knew the only thing stopping him was his own cowardice, but he couldn't bring himself to overcome it.
Chief amongst it all, he regretted his first fight against All Might. He could've saved himself a lot of troubles if he simply crushed his head instead of checking his phone.
Though looking back on his actions since, he wouldn't change that for the world. And the reason behind that was Izuku.
His boy had grown to astronomical proportions, shooting through the ranks and reaching the number 1 spot in a year.
Sure, Hisashi may have thinned down the competition a little by stealing Hellflame and bestowing a much weaker fire quirk upon Endeavour, but it didn't matter. He did everything in his power to ensure Izuku achieved his dream, and though he may not have given him a quirk, he was content in the fact that he pushed Izuku up to the position through Tomura's sacrifice.
Then there was the harem.
He'd be lying if he didn't push the idea for less savoury reasons at first. At the time, through his frustrations at his own bad parenting, he thought showering a teenage boy in female attention would make up for it.
In hindsight, he could see it was a horrible plan, but somehow, it worked out more perfectly than he could imagine.
A few days prior, Hisashi wanted to take a look at his son's romantic life, just to ensure the harem was going strong. He expected to see the women simply fawning over Izuku; trying to one-up each other in an attempt to be his favourite, but reality shocked him much more.
They all looked happy.
Not the superficial happiness that he envisioned, but genuine love.
The girls all enjoyed each other's company to the same extent that they loved Izuku's, and it was heartwarming to watch.
He wouldn't change the last few years of his life for anything.
And now, with the knowledge that the almighty keikaku was fulfilled, he could finally relax—
"Detroit Smash!"
Hope you enjoyed the one-shot!
