Izuku's eye twitch as he stood in front of the door to the support department.

Or rather what was left of it.

The molten slag that was once the heavy duty doors designed specifically to contain Hatsume's regular explosive accidents, was now a cooling puddle on the ground and the interior was charred black.

Normally such a sight would send Izuku into frantic, overprotective dad mode. Were it not for the coded message that Nezu had left taped to the wall.

"So… this is bad right?" Mitsuki asked nervously from Izuku's arms and he sighed in response as he snapped his fingers, igniting the note in icy blue flames that impossibly left frost instead of scorch marks.

"Nezu had to relocate everyone because they were running out of room and the girls trapped in the building were starting to suspect they were hiding here. The damage was to cover their tracks" Izuku explained with a horses voice and half lidded, puffy, red eyes.

Mitsuki quirked an incredulous eyebrow at him.

"Isn't this a bit overkill?" she asked but Izuku just gave her a deadpan stare.

"To be honest. It might not be enough if any third year students or teachers are still in the building" Izuku replied flatly, casing Mitsuki's jaw to drop in disbelief.

Izuku just sighed as he turned around and started making his way down the hallway. He was mentally, and to a lesser degree, physically exhausted. He wasn't sure how much longer he could keep this up, especially if more women like Mitsuki happened to be in U.A. for whatever cosmic reason.

All Izuku could do though was take a deep breath to center himself as he made his way to the new location Nezu had given him.

He stopped for a moment though as his body ceased up.

"Shit" Izuku thought as he tried to hide his discomfort.

"Izuku… is everything alright?" Mitsuki asked with concern but Izuku plastered on a fake smile.

"I'm fine… just tired" he answered before forcing a bit of One For All through his body to prevent him from deflating like All Might.

"You're starting to hit your limit" the First wielder stated mentally as Izuku began running down the hallway when he heard some girls heading his way.

"I agree that you need as many quirks as possible for when you fight my brother. But I think you're making too many, too fast. My calculations for how many quirks you could handle before One For All evolved, didn't account for your quirk getting stronger as it was used or you suddenly not holding back" he continued as Izuku grimaced from the immense heat he felt building up inside him and the thousands of little needles he felt all over his body from the stress of all the changes happening to it.

"We'll deal with that latter. Right now I need to get out of this building" Izuku replied as he ran.

"THERE HE IS!" a girl with rainbow hair screamed as she rounded a corner, followed by the girl with a canine quirk he'd seen before.

Mitsuki couldn't help but yelp in shock as the dog girl immediately charged at them on all fours while foaming at the mouth.

She closed the gap with incredible speed and leaped at them.

SLAM!

Only to pancake herself on the shimmering barrier that Izuku placed between them, blocking the entire hallway.

By the time the other girl had made it to the barrier, Izuku was already gone, causing the two the howl in despair.

Izuku meanwhile was desperately gulping down hair as he skidded around another corner and blasted down the hallway at inhuman speeds.

"Why are you running? You know you can just teleport to Ochako right?" First asked as Izuku tried to calculate the best exit strategy.

"I don't know how that quirk will affect the babies" Izuku replied as he glanced down at Mitsuki's belly.

Izuku suddenly skidded to a halt and winced as, out of nowhere, he was assaulted by a chorus of high pitched squeals.

He turned around and gawked at the gaggle of schoolgirls all charging at him as if he were the hottest new emo rock idle.

Izuku turned to run, only to find more coming from the other direction.

"Shit! That got organized!" Izuku yelped as he looked for a way out. He then turned his attention to the shuttered windows next to him and grit his teeth.

"Cover your ears" Izuku instructed the panicking woman in his arms and she complied after a moment's hesitation.

Izuku then aimed his palm at the window as he still held Mitsuki up and smoke wafted up from it as he activated One For All.

BOOOOOOMMMM!!!

Wind gusts and shockwaves knocked the girls back a little and bought Izuku a few seconds as his feet started smoking.

BOOM!

Two more, smaller explosions reverberated from beneath his feet, propelling Izuku out of the building as he left a duplicate behind to seal the hole before the girls could get out.

Mitsuki screamed as they flew through the air and Izuku winced as she made her best attempt at strangling him as she clung to him in fear.

Izuku puffed his cheeks out as he struggled to breathe and tapped at her arms around his neck.

Mitsuki continued screaming, even as they landed on a shimmering platform of air that Izuku made. It took a few moments for her to calm down and realize Izuku was starting to turn purple.

"Oh… sorry…" Mitsuki sheepishly apologized as she looked away in embarrassment while continuing to hyperventilate.

Izuku meanwhile gasped for breath as he stood there with her still in his arms.

"It's ok" Izuku wheezed out as his palm and feet still smoldered a little.

He then shook his head and looked around to get his bearings. He was somewhat dismayed to see the sun starting to go down. It wasn't late yet, but the sun was unmistakably continuing it dutiful march towards sunset.

"Have I really been running from girls and having sex all day?" Izuku thought with disbelief. He sighed as he shook off his issues for later and focused on one of the training grounds.

"We're going to have to fly if we want to get there fast and without getting spotted" Izuku informed the woman in his arms.

Mitsuki's eyes shot wide as her hormone flooded mind registered his words.

"Wait wa-AAAAAAHHHHH!!!" Mitsuki screamed as Izuku leaped into the air and didn't come down. She was so worked up that she didn't notice Izuku turning them both invisible or the fact that they weren't slowing down but she didn't feel the acceleration.

In fact they were now moving at super human speeds but she didn't feel any different.

In the span of only a few seconds, they landed in one of the training grounds. Specifically on top of one of the fake hospitals.

Izuku felt guilty for putting Mitsuki through all this but he was still mentally burned out. He still gave her time to calm down before moving again though.

After a few more moments of heavy breathing, Mitsuki managed to calm down for the most part.

"Ok… I think I'm ok… please don't do that again…" she said breathlessly.

"Sorry…" Izuku replied with a grimace as he started walking towards the doorway down into the building.

Still invisible, Izuku made his way down through the mostly bare building until he came up to a seemingly innocuous room on the bottom floor.

Izuku hummed as he walked into the empty room. There was absolutely nothing of note aside from a desk and a few chairs. Not even nice ones at that. The walls weren't even painted, it was just a bunch of modular squares.

"Nezu's note said this was the place" Izuku muttered as he checked the area. Once he was sure there weren't any girls in the immediate vicinity he deactivated his invisibility.

Izuku continued to hum in thought as he looked around the room, only to freeze up as the room suddenly shook.

"Whoa!" Mitsuki yelped and Izuku quickly found his balance as the room began to descend.

Izuku just gave a deadpan expression as the elevator made it's way down.

"Ah, leave it to Nezu to be over the top with his backup plans" Izuku muttered as they continue for a while before coming to a stop in front of massive doors that slowly creaked open.

Izuku just sighed as he walked through the doors and down a long hallway while the elevator went back up.

Mitsuki felt very awkward as Izuku carried her.

"Is this normal for this school?" she asked sarcastically.

"Pretty much" Izuku answered anyway as they came up on an oddly normal, metal door which Izuku was able to just push open.

As soon as Izuku stepped inside, twenty one sets of eyes immediately locked onto him.

"Deku!/Izuku!" Everyone exclaimed with relief, joy and concern upon seeing him safe but clearly distressed.

For his part, Izuku felt immense relief to finally have safe harbor with his girls. He was so relieved that he wasn't even overwhelmed by the fact he had a harem now or the shear size of it. He did however, feel very awkward and confused about the state they were in.

"Um… hi everyone… what's going on here?" he asked bashfully, to which the girls all glanced down at the breast pumps that were currently in use.

Several girls blushed profusely and attempted to cover themselves.

Mirko was not among them.

The rabbit hero smirked at him as she patted her belly.

"Your quirk might be making up produce more, but we all still only got two a piece. That's hardly enough to feed all these kids at once" she said with no shame, much to the embarrassment of most of the other girls.

"A-anyway! How are you doing Deku! You look kinda down…" Ochako quickly changed the subject, her intense blush giving way to concern.

Izuku sighed as he set Mitsuki down on an empty gurney.

"I had to deal with some personal issues and… well it didn't end well…" Izuku muttered as he let his mind relax.

"It's ok Izuku. We're here for you" Ochako spoke soothingly as she rubbed his shoulders and Izuku blushed as he realized he'd subconsciously crossed the room and sat down next to her.

Some of the other girls look a little jealous but all of them accepted that Ochako would always be Izuku's first.

Izuku seamed to snap out of his funk a little as Ochako worked the tension out of his shoulder and he blushed further as he realized he was now practically laying his head next to her on the gurney.

He couldn't explain how it happened, it just did and it felt like the most natural thing.

Ochako smiled as she watched him visibly relaxing thanks to her efforts and she wiped some of the tear stains from his face.

"Here, do you need some water. You must be thirsty after so much… well you know…" Ochako trailed off with a blush as she reached for the water next to her bed.

Izuku's face turn atomic red and he turned into a babbling mess in response, though not for the same reason Ochako felt awkward.

Someone else clearly picked up on the real reason though as they laughed at the display.

Izuku and Ochako both looked to the source of the laughter and to his surprise he saw it was Hatsume. Unrestrained and just sitting in her bed, seemingly content with the fact several girls had more babies than she did.

"Hatsume! A-a-are you… um… you're not mad anymore?…" he asked feebly, which only made her laugh harder and more deranged.

"Oh no, I'm definitely pissed to see another girl outdoing me… but it's gone so far I've kinda looped back around. Besides, I've had plenty of time to design our love suite…" she answered with a sinister aura at the end that made Izuku's skin crawl.

"But I'm content to wait until this all blows over and this first batch is out. You can thank the other girls for helping to talk me down" she suddenly added with no malice whatsoever, like a switch had been flipped.

Izuku sighed in relief at hearing that and sent glances of gratitude to the rest of his growing harem.

Only for Hatsume to then give a sinister chuckle.

"As for you Ochako-sama… I think hydration is the last thing our baby daddy needs. I mean, just what is it you think he's been doing this whole time" she giggled as she squished her boobs together, squeezing more milk into her breast pumps.

CRACK!

You could hear the fragile psyches of all the girls in the room shattering at that moment.

Well, most of them…

Mirko just smirked at the new material she had to tease Izuku and the other girls with and Himiko was still unconscious.

The water bottle fell out of Ochako's stiff hands as she sat there frozen and Izuku shrieked as he curled up into her side, now lying fully on her gurney as he hid his face.

Had this been any time before, he could refute Hatsume's words. But Izuku knew for a fact he'd gone the extra mile with Mitsuki and as a result he actually wasn't dehydrated at the moment at all, in spite of all the tears he'd shed.

An awkward silence filled the room for a moment. It was soon broken by a fake cough and Izuku peeked out from his hiding place to see Rei scratching the back of her head.

"Well… setting that aside for now… who might this be?" she asked in an attempt to divert the conversation and brake the tension, though it seamed to set Izuku's nerves on edge again.

"T-t-this is Mitsuki… Mitsuki Bakugou…" he answered and once again could hear the world shattering around him as all the U.A. girls stared with wide eyes.

"I mean… I guess it should have been obvious given how similar they look…" Jiro muttered while hiding her mouth behind her hand.

"Well I guess we know why Izuku was so stressed out now, kero" Tsuyu added bluntly.

"A-anyway!" Izuku suddenly cut in before things could get any more awkward. He took a moment immediately after to calm down and clear his throat.

"Um… Mitsuki, this is…" Izuku trailed off as he glanced around the room at everyone and felt his head start to spin at the size of his harem and how he was supposed to introduce them all.

Izuku saw an out though as he glanced over at Rei.

"This is Rei and her dau-…" Izuku froze mid sentence, his face showing abstract horror at what he was about to say.

"How the hell am I supposed to do this without sounding like Mineta!?" he though in a panic.

Izuku gulped as he gestured to the girls in question and powered through.

"A-and Fuyumi… they're here for…" Izuku trailed off in a panicked daze before suddenly blinking in confusion as he focused on the two girls.

"Actually why are you two here? I never got to ask you" Izuku asked with a quirked eyebrow.

Fuyumi seamed to perk up a little at the subject.

"Oh, I got hired to teach the general courses here at U.A. and came in for orientation and mom came to support me and see Shoto" she said with pride.

Izuku and many of the girls were impressed. It wasn't often a civilian got hired to U.A. even for general work.

Izuku's mood plummeted though as he saw the gears turning in Mitsuki's head regarding Rei and Fuyumi's relationship.

Before he could spiral though, Ochako placed a hand on the side of his head and gently made him lay it against her belly.

"Leave the girl talk to the girls Izuku. You just rest" she cooed gently while stroking his hair.

Izuku was about to protest when another voice joined in.

"Listen to your woman brat. She's been wrangling everything here petty well so far, so she knows what she's talking about" Recovering Girl advised from Mitsuki's side as she began examining the woman.

Izuku was surprised that she didn't seam more angry at him, but he was too mentally exhausted to care and decided to heed their advice as he closed his eyes and leaned into Ochako's belly, where he could hear their babies heartbeats and movements.

"Well… I can already tell what the hierarchy is here" Mitsuki muttered quietly as she watched the tender display.

Recovery Girl just gave an exasperated sigh. She was still a little ticked at Izuku for getting yet another girl obscenely pregnant. But she wasn't so addled by age yet as to not recognize Izuku's own mental stress and fatigue or the extenuating circumstances.

So she decided to let Izuku off the hook for the time being and let him rest before ripping him a new one and then tossing him to the wolves again.

And make no mistake, there were still plenty of she-wolves to pacify out there.

"Enjoy your rest while you can Midorya" she muttered as green haired hero fell into a light slumber while she worked.

Q/L -

——————- Fuyumi - 15

Cocytus Flame

"User produces cold flames from their body that burns an icy blue color. The flames can still burn objects and individuals but will leave them freezing instead. The flames do not so much burn though and instead they suck the heat out of whatever they touch. Temperatures can reach nearly as low as absolute zero, but this runs the risk of injuring or even killing the user"

14 - ?

——————- Mitsuki - 20

Explosion Mk.2

"An upgraded version of Katsuki's quirk. Explosion Mk.2 is superior in almost every way. It is capable of greater control and higher explosive yields and can detonate from any part of the body. It also strengthens the body for a greater threshold before backlash sets in. It also grants modified brain chemistry to better deal with anger without sacrificing emotional expression. Unfortunately this quirk does have a tendency to cause temporary deafness to protect the user from permanent ear damage due to the higher explosive power"

19 - ?

—————- Pixie Bob - 12

Inertia Control

"Allows the user to control the inertia of themselves and anything they are touching. This allows them to move at extreme speeds with minimal effort and without suffering whiplash. It can also lessen heavy impacts against their body or anything they touch if they are quick enough. Unfortunately prolonged use can cause heavy fatigue and headaches, and the quirk only slightly enhances perception, so extreme speeds can still be too much to process"

9 - ?

—————-Lady Nagant - 4

Wind Walker

"A derivative of one of the quirks Nagant received from All For One, the quirk allows the user to force air molecules together into hard surfaces for as long as the user maintains focus. Unfortunately, the genes for the original quirk could not be fully copied do to them not being native to Nagant's body, so this quirk is only as close a copy as Izuku could manage while still adding some improvements, such as the barriers being stronger then the original and not requiring physical contact to be activated and maintained. One unintended effect added is the shimmer that is produced when in use, making the barriers not truly invisible like the original quirk.

2 - ?

A/N -

I'm having some technical difficulties on my end that may slow or even stop updates for a while, so bear that in mind if things just stop for any reason going forward. I'll try my beast to fix things.

Now, one of the reviews from AO3 actually brought up the little tidbit of not being able to actually feed all the kids but it took so long to come back around to the girls that can't remember their name. Sorry about that.

And likewise it's getting hard to keep track of all the quirk idea along with my own, so sorry if I miss any of you while adding them.
