Chapter Text
"...that's it?" the purple girl asked. "You take this long to tell this story about how you and your classmates had sex with Izuku, and you just end on a random out-of-nowhere non-sequitur?"
The violet girl sitting next to her nodded, "Yeah! Like, that was just a lame ending! It wasn't even that funny!"
Mina blinked before she pouted at her daughters, "Geez, who raised you kids to be this snippy!"
"Nobody raised us." the violet girl answered. "We're not even real."
"...eh?"
"Yeah, we're just a hallucination caused by you headbutting against the door from earlier." the purple girl shrugged.
"What are you guys talking abou-"
"ASHIDO!"
Mina jolted as she was brought back to the familiar location of UA's school grounds, blinking in a daze. "Wha-...? What happened?" she looked to see Ochako and Kyouka with rather concerned looks on both their faces (Mei was there too, but she didn't look too concerned, that bitch).
"What do you mean, what happened?" Kyouka answered, "You jumped out of the bushes like a madwoman, then just froze up and stared at that wall for what felt like two months!"
"Are you OK, Ashido-chan?" Ochako asked.
Mina blinked and tried to shake off the last remaining cobwebs still in her head. "Yeah, I'm fine, but maybe remind me later to go to Recovery Girl's office. BUT, HEY-!" she then immediately aimed a finger at Kyouka, "Don't try to change the subject! I heard everything!" then crossed her arms with a very smug grin on her face, "Well, well, well~! Now the shoe is on the upturned table! Little Miss All-High-And-Mighty-Wouldn't-Even-Talk-To-Her-Friends-About-Their-Sex-Lives-And-Help-Them-Interrogate-A-Bunch-Of-Girls-About-Theirs has debased herself to the level of her gossipy friends, has she~?"
Kyouka flinched, her face quickly growing red as she bit her lip, wanting to stand up for herself, but also having to admit to something absolutely terrible: that Mina was right about something.
"And you-!" Mina then immediately turned to Ochako, getting the other girl to squeak, "Don't think you're getting off scot-free! What's with all this casual "I know you did the dirty deed done with Izuku, and it's OK" business! You've been crushing on him longer than any of us, and you're the crazy jealous type!"
"I-I am not the crazy jealous type!" Ochako defended herself with a squeaky voice.
"Ochako, you crushed an apple with your bare hand that one time Toru accidentally - and I am being very generous towards my dear friend's intentions when I call it 'accidentally' - bumped into Midori and kissed him during our Christmas party!"
"Wait..." Mei blinked in a rare moment of cognizance tot he world around her. "That time you said you accidentally threw one of my Babies at my head when I was trying to get Izuku to take his shirt off... I'm starting to wonder if it really was because you just sneezed!"
Ochako opened her mouth, trying to find words to justify herself, before staring at Kyouka for any help.
"Sorry, Uraraka..." Kyouka said, "Sometimes we tend to hide sharp objects whenever Tokage, you and Midoriya are in the same room because of how flirty she can get."
Ochako let out an indignant noise that was really only a squeak as her cheeks flushed pink.
"You heard the slut!" Mina said, much to Kyouka's shock.
"S-Slut!? Need I remind you you slept with Midoriya too!?"
"Now, spill it!" Mina ignored Kyouka, focusing back on Ochako. "What's the deal with this new Chako! Unless.... you-!!"
"Oh, here you are, kero." Mina and the others blinked, looking at Tsuyu as the froggy girl approached. "I've been looking all over, Ochako-chan."
"TSUYU! TSUYU!" Mina rushed over to her side, "It's great that you're here! I've just cracked a bombshell the size of Bakugou's ego! Get this, Chako here has actually-"
"Slept with Midoriya?"
"..." Mina froze, her mouth hanging open for a few seconds. "...you KNEW!?!?"
"Of course I did." Tsuyu said, "Ochako-chan's my best friend. We tell each other everything because we trust one another unconditionally, kero." she looked at her BFF with a wide and warm smile, Ochako returning it right away.
"B-B-But earlier-! This morning! I brought up Chako, and you agreed with me that she couldn't have had sex with him!"
"I never said that." Tsuyu plainly said. "You said Ochako-chan couldn't have been Midoriya's first, which seemed like a reasonable assumption. But I never said I thought she hadn't ever slept with him."
"So all this time, you were just trying to lead me away from Chako!? What a sneaky move, Tsuyu!" Mina huffed.
"You're the one who ruled her out at the start, kero. I didn't have to lead you away from anything." Tsuyu said. "It wasn't until Komori-san suggested her again that I felt I should come warn her."
"Thank you, Tsuyu-chan." Ochako said, Tsuyu croaking pleasantly in response.
Mina rubbed her eyes, taking in a deep breath before-"ALRIGHT! I am getting to the bottom of this, if it's the very last thing I do!" she immediately grabbed Ochako and Kyouka by their wrists, ignoring their cries of protest as she started dragging them away. "Hatsume, Tsuyu; COME ON!"
Tsuyu and Mei blinked, staring for a moment before they followed Mina back the way they'd came.
---------
The Class B dorm was getting quite busy, as every girl from both classes, along with Nejire and Chikuchi, and several female Pro Heroes summoned here on a maybe-slightly-bogus-emergency call, had been gathered there.
Mina held her arms crossed, eyes shut in deep contemplation. After what felt like an hour of tense silence, Momo finally raised her hand to ask:
"Excuse me, Ashido-san? What was so urgent that we all had to meet here so quickly?"
Mina didn't answer straight away, slowly exhaling. "Because I believe someone here..." she then turned to face the crowd, "Is lying."
This earned a light gasp from the room, some of the girls muttering in surprise.
"It was my belief that I could easily get to the bottom of this mystery by simply following the breadcrumbs backwards, but I should have considered the possibility of someone lying about their time with Izuku more seriously!"
"Wait, you chicks are still on this?" Pro Hero Miruko spoke up, "Isn't it obvious? It had to be Midnight over there!" she pointed at the R-rated Hero on the other end of the room.
"N-No, it wasn't me! Honest!" Midnight quickly defended herself, "I may taste the eye candy every now and then, but I would never consider involving myself with a student! It wasn't until Thirteen talked to me about her affair with him that I grew curious!"
The smaller woman squeaked, Thirteen quickly raising her hands to defend herself. "Y-Yes, OK, I-I got together w-with Midoriya when I know I shouldn't have, b-b-but I couldn't help it! I accidentally walked in on him and Ryuukyuu in an empty classroom, a-and I was just... I-I was weak! I couldn't control myself!"
"I don't think anyone in this room really has a right to judge you, so just chill, will ya?" Mount Lady said as she slouched on the sofa. "Just take one look at what he's packin', and it's off to the races with just about anyone!"
Miruko grinned. "Like a horse, right?"
And the entire room sighed blissfully. "Like a horse..."
The Dragoon Hero Ryuukyuu then cleared her throat to defend herself. "While that may be true, I am not lying either. While I won't deny I may fit the profile of the experienced woman you're after-"
Nejire blinked at her boss, then lightly tugged on her costume. "Hey? Hey, Ryuukyuu? Didn't you tell me it was your first time and you were really nervous about it, and that Izu-kun pretty much guided you all along the-mmf!"
Ryuukyuu quickly covered her protege's mouth, trying desperately to ignore the blush over her cheeks in the hopes others would ignore it to. "I-I am being genuine when I say I did not teach Izuku anything he didn't already know! While he seemed nervous at first, he definitely knew what he was doing. I know I don't have any proof of it, but-"
"No, I believe you." Mina said. "In fact, I don't believe our woman is among any of the Heroes here."
"...wait, then why did you even call us here!?"
Mina just looked at her. "I didn't call you. I only called Midnight-sensei and Thirteen-sensei to get some facts straight; the rest of you just followed them!"
Miruko slouched back in her chair, crossing her arms. "Well ya put this damn question in our heads, and we wanna know who this bitch is too!"
"Anyway..." Mina continued, "The person we're looking for would've needed constant access to Midoriya. It needed to be someone he could hang out with on a daily basis, without drawing any suspicions. With that in mind, I also believe Class B is telling the truth."
Setsuna blinked. "Then... you're saying it's someone from Class A?"
"Correct." Mina said with a firmness in her eyes, looking over to her own classmates who all cowed at her imposing glare. For a few but agonizing seconds, Uraraka Ochako, Yaoyorozu Momo, Jirou Kyouka and Hagakure Tooru were left to sweat.
Tsuyu was as cool as a cucumber though. "I know I'm not the one lying, kero. Sorry, Mina-chan."
"It's OK, I know you didn't do it either, Tsu-chan! You wouldn't have gone along with this thing if you weren't genuinely curious." she smiled at the frog girl. "Oh, and you're off the hook too." she vaguely motioned in Momo and Kyouka's direction, both girls sighing as they felt the spotlight taken off their face. "Which only leaves..." Mina's eyes raised again, staring down the last two girls. Ochako squeaked, sweating nervously, while Tooru was on the edge of her seat.
"Chako. You've been acting strange lately. You seem to know more about what's going on than most people here. You've seemingly gotten over your jealousy issue, and took it upon yourself to find Midoriya once you knew the rest of us were snooping around his business. I don't have a doubt in my mind you've gotten together with Midoriya in the past... the question is simply: when?"
Ochako gulped as she trembled in her seat.
"...and you." Mina then looked straight at the invisible girl.
Tooru (presumably) blinked, raising a hand to (presumably) point at her (presumably) confused expression. "Me? But I didn't even know about any of this until you brought it up!"
"True." Mina nodded" You claimed this morning that you tried to sneak into Midoriya's bedroom at night, but couldn't because Yaomomo beat you to it..."
"That's right!"
"But you'll also recall Yaomomo saying she placed down motion sensors around Midoriya's room. And as early as last Thursday, you were still complaining to me that you still struggle sneaking around mechanical devices. So I wonder, did all of your luck just line up on that specific night to allow you to dodge Yaomomo's sensors?"
Tooru flinched, her clothes trembling.
"You know what I think? I think you were already there. Inside Midoriya's room." Mina stepped just a bit closer, aiming her judging obsidian eyes straight at her closest friend. "I think you like to watch."
There was a collective gasp, followed by a pitiful shriek from Tooru.
"I-IT'S TRUE! IT'S TRUUUUEE! I-I'M SO SORRY, YAOMOMO! I'M SO SORRY!" Tooru collapsed on the floor, burying her head in her arms as let out tears of guilt.
"Tooru-san..." Momo quickly knelt down beside her friend, placing a hand on her shoulder to comfort her. "It's OK. I'm not mad, truly."
"Of course you're not... you knew she was there."
Momo and Tooru immediately froze like statues at Mina's accusation.
The pink girl quietly chuckle. "Come on, girl. You were so nervous you put down motion sensors outside of the room. Don't you I think I don't know you'd be so paranoid you'd check his room from top to bottom as well?"
Momo poured sweat down her furiously blushing face, even as she remained paralyzed.
"You found Tooru. You let her watch regardless. It made you feel like you were part of a study, which only made things all the more exciting."
Momo began trembling as her embarrassment reached critical levels. "I-...I thought you said I wasn't a suspect..."
"I never said that. I was waving at Jirou; you just happened to be next to her." Mina smirked. "I believe in Jirou's indignation from today and yesterday. She just ultimately succumbed to temptation, like every one of us here. But you... I gotta say, Yaomomo, I really underestimated your acting chops. That whole show you put on in the kitchen this morning?" she clapped. "Bravo, madam!"
Momo let out a sigh, her embarrassment turning into shame as she gave up the act. "How... how did you know..."
"I'll admit, all I had was conjecture at first. If any one of us would have the drive and the hunger for knowledge to read every guide to love making and sex, and gather an immense knowledge base of how to take good care of one's partner in love making, it would definitely be you. What further tipped me off... the hoodie."
Looking up at Mina, Momo blinked.
"You said you liked to wear the hoodie even in summer because it's comfortable. While that might very well be true... you weren't wearing a hoodie in Jirou's room." Mina explained. "So why would you leave Jirou's room in the third floor, go all the way to your room on the fifth floor to put on a hoodie, only to then make the trip to the second floor to meet with Midoriya? I know you couldn't be lying about wearing a hoodie, or anything else you said, because then Tooru would know you were lying. So, my theory: you got the craving to meet with him again after everything I said; you text him you'll come to his room in a few minutes, but you first need to get ready, because what Midoriya and you are really into... is roleplay!" she aimed a finger at Momo, "The whole story about you coming over to Midoriya's room to study went down exactly as you said, but all of it was planned ahead! Tooru being there that night was just a happy coincidence, giving you the perfect alibi to claim it was your first time together with him! But, as I said, all of this was just a theory, until you didn't react to Tooru's admittance of being there that night. While I've no doubt you would've forgiven her either way, you would have been much more shocked if that information was new to you. That told me straight away, you knew from the start."
Momo slowly bowed her head in shame. "It's true... i-it's all true..."
"Yaoyorozu..." Kyouka quietly said, seeing her friend look this friend. "You didn't have to lie to us like that. We're your friends."
"I-I know, but... I was embarrassed, a-and after the way you reacted to Ashido's escapades, I-I felt too ashamed to admit to any of it... I thought my secret would be safe right away, but I never thought Hagakure-san would go and tell Ashido what she saw..."
"Tooru's thirst for gossip outweighs even her own self-preservation instincts, I'm afraid." Mina added.
Tooru shrunk a bit, rubbing her head. "Th-That's true..."
"Now, with all that said..." Mina continued, "I'm not gonna lie and say my theories don't have their flaws." she looked over at Tooru, "Tooru, while I believe you've been seeing Midoriya for much longer than you've admitted, and your Quirk is perfect to let the two of you meet up in total secret... I also believe your interest in the investigation to be genuine, because the thought of finding our Patient Zero and being able to watch her in action together with Midoriya was just too enticing." she then looked at Momo, "And Yaomomo, while I'm certain you had the knowledge and the will to, together with Midoriya, learn the ins and outs of sex in your own dorky-but-highly-effective way... well, you're just not the type to initiate something like this. Something had to plant the idea into your brain first that Midoriya was even sexually active in the first place."
"Th-Then, how would that even happen?" Setsuna said, literally on the edge of her seat.
"As it just so happens..." Mina continued, "Yaomomo lives on the fifth floor of our dorm. And who would happen to inhabit the form room directly below her, on the fourth floor?" Mina moved her head looking directly at the answer.
And Ochako grew extremely pale as she felt the whole room gasp and place their undivided attention all on top of her.
"Chako-chan..." Mina said, "You remain the only question mark in this entire room, but one thing is clear: you're well aware of Midoriya's friends-with-benefits escapades. You're in on it, and I believe you have been from the very start. And unlike anyone else in this room, you have no alibi, no reasonable doubt to indicate you got the idea from someone else. Out of all of us here, you had the most reasons to open up to Midoriya, tell him the truth, but also explain to him that, due to how important your studies are, that you weren't interested in anything too serious. And so, an agreement was made..." Mina turned and paced away.
Ochako didn't say anything, just shrinking into the couch as her face grew red.
"All signs point to one solution..." Mina said, crossing her arms as she closed her eyes, "But even those signs aren't based on hard evidence. Still, with all of that said..."
Everyone leaned forward.
"It's my belief that Ochako..."
Expectation was at an all time high, eyes widening and brows sweating.
"Is-"
Click!
"Excuse me?" Izuku peeked into the common area from the front door, "Sorry to interrupt, but as anyone seen Uraraka to...day....?"
He blinked, seeing an entire room of classmates, schoolmates, Heroes and Sidekick all staring directly at him.
And the mood in the room got dangerous, and he felt like he was being stared down by an army of hungry panthers.
"IT'S HIM!"
"THERE HE IS!"
"GET HIM!"
All at once, a sea of girls jumped at him, grabbing his shirt to yank him into the room and slam shut the door behind him.
"Why're we wasting time when we can just wring it outta him!" growled Mount Lady!
"Yeah! Spill it, Izuku!" said Setsuna.
"Sex! Sex!" demanded Pony as best she could in broken Japanese.
"Who's the bitch that took your virginity!?" roared Miruko as she lifted Izuku off the ground by his shirt, "Was she better than me!? I'll kill her!"
As more and more chaos surrounded him, every woman in his life shouting at him to come clean and answer their question overwhelming him as he babbled incoherently, unable to even come up with the necessary brain functions to come up with an answer to-
"IT WAS ME!"
The crowd all turned to see Ochako standing on top of a chair.
"I-...I admit it! It was me! Y-You got me! I was Izuku's first! W-We started this four months ago, four before Hero Lecture Day, and... l-like Mina said, we just... had an agreement..."
She was met with confused looks, before Miruko let go of Izuku and asked- "Wait, how's that supposed to work! You're just a brat; how could you pick up on all the stuff he knows!?"
Ochako's face grew redder. "W-...We do it... a lot..."
"..."
"...a-a LOT... I guess w-we just kinda... figured out what works and what doesn't..."
There was a short moment of silence, before Midnight said: "That does make sense... what better to motivate two lovers to get better and better than youthful spirit!"
Itsuka nodded. "I... guess that makes sense..."
"Yeah, that tracks." Kyouka said. "I mean, we know Midoriya's a really fast learner anyway, and Uraraka's no slouch either."
The crowd seemed to be well in agreement, muttering amongst each other about how they were glad this whole thing was finally over with.
Which only meant one thing- "Well, now that that's outta the way-" Miruko picked Izuku off the floor, getting him back to his feet, "All this sex talk got me mad horny! So, you, me, let's tear the damn walls down!"
"H-Hey! You're not the only one with needs here, you know!" Mount Lady barked, "Why should you get dibs!?"
"Yeah!" said the rest of the crowd, which quickly devolved into an argument over who got Izuku first.
"HOLD ON A SECOND, WILL YA!" Miruko shouted, "Why do we gotta take lots anyway? Maybe we should find out if Green Machine here's man enough for all of us~"
The crowd stopped and went silent for a moment, staring at Miruko, then at Izuku.
And that feeling of being watched by very hungry panthers quickly returned, just in a different sense.
"That's a great idea!"
"A marvelous idea!"
"I wish to partake in this."
"Sex! Seeeeex!"
"The gym building is completely empty today! Nobody goes there!"
"Let's go there right now!"
"You better be good and ready, I-zu-ku~!"
The crowd talked amongst themselves as they left the building, chatting and giggling along as they all made their way to the assigned place, leaving behind Izuku to mentally and physically prepare himself.
At the moment, he just felt like a scarecrow who was really bad at its job and just got pecked to bits by a murder of crows. His mental faculties did return a bit when he felt Ochako brush his cheek with her hand and give him a kiss, mouthing something to him that only he could hear. He smiled at her, and she went to follow the crowd to the gym.
Izuku sighed, feeling much more relieved even if he didn't fully understand what had just happened.
But then he felt a chill on the back of his neck, stiffly turning around to find Mina still standing there, arms crossed, staring him down with a judging look in her eyes.
"U-Uhm... M-Mina, is-"
"I don't buy it."
"E-Eh...?"
"As I was going to say before I was so rudely interrupted... even if there's a lot pointing towards it, I don't believe Ochako was your first. And I don't believe you guys just 'figured it out' as you went along either."
Izuku flinched, the nervousness quickly apparent on his face. "W-Well... th-that's... y-you see-!"
Mina kept her glare on him for a few more seconds, but then finally, just sighed and relaxed. "But... I know Ochako only said that because she was being a good friend." she stepped closer to Izuku, "Look, I took this way too far. I didn't mean to get a mob breathing down your neck like that. I'm sorry, Midori."
Izuku blinked, but ultimately just smiled gently at the pink girl. "It's fine, Ashido-san. It just took me by surprise, that's all."
Mina smiled back. "Still, why the secrecy anyway? I mean, you seem pretty comfortable talking about all of this as is, but why's this one detail one you can't bring up?"
"W-Well... maybe it's silly..." Izuku rubbed his head as he blushed, "But the truth is... I just don't think anyone would believe me."
Mina raised an eyebrow at the answer, unsure if she was satisfied by it. But, in the end, she'd taken this far enough, and it wasn't important if she was satisfied or not. She giggled and walked past Izuku, poking him on the forehead as she did so. "I'll pry it out of one of these days, Midoriya Izuku. Now, you better be a gentleman, and not let all of us wait for too long~" with a wink, Mina skipped off towards the gym along with everyone else.
Izuku smiled and let out a sigh. This definitely wasn't how he was expecting his day to go.
But a Hero's gotta do what a Hero's gotta do...
It was quiet. It was always quiet there, that's what made it so relaxing. The dark smoke hovering over a nearly-endless expanse, a place that wasn't a place, without terrain, without wind, without smell, without up or down.
"Someone had an eventful afternoon."
Her voice called to him, urging him to open his eyes. Through the smoke, the form of Shimura Nana was perfectly clear, like a light in the endless dark.
"Ah, Sensei... y-yeah, it's... been..." Izuku chuckled weakly, "I'm just taking a small break..."
"I'd say you earned it." Nana chuckled.
"...uhm... were you, uhh-"
"Watching? Well, you can't blame me for being curious can you?" she chuckled again with a playful grin. "My cute student was put through his biggest challenge yet; of course I was going to want to see how he performed!"
Izuku chuckled a bit awkwardly. "R-Right..." he then couldn't help but ask: "Uhm... a-and...?"
Nana hummed. "Well, given the circumstances, I'd say you performed quite admirably!" she then reach behind her, pulling out a ghostly notebook, "Still, I found some flaws we could improve on for the next time.
Izuku let out a groan at "next time", as even in his internal ghostly realm of One For All where he is nothing more than a bodyless spirit, he could feel how sore his entire body still was in the real world.
"Now, now, chin up!" Nana lightly punched his shoulder, "This is what you asked help for, right?"
"A-All I asked was if you could help me not be so shy around girls!" Izuku said.
"And my method worked, didn't it!" Nana chuckled again, giving him that devilish grin again. But her grin softened into a smile, as she lay down on the groundless floor next to him. "Izuku... you know you can always stop any time you want to, right?"
"N-No, I know that..." Izuku answered, opening his eyes to look at her, "I don't want to stop, really! Maybe it's silly, but... all my life, I wanted to be a Hero. I wanted people to feel safe around me, to help them in any way I can... deep down, all I could ever want is to make people feel happy... secure..." a tired but genuine smile appeared over his lips. "Sure, this is... an unconventional, a-and very specific way of doing that... but when I see the look in their faces... making them feel as good as I possibly can, that just makes me feel happy. And I have you to thank for, Sensei."
Nana chuckled, leaning over to place a soft kiss on his forehead. "You're a good student, so don't undermine your stake in all of this. True, this whole scenario might be unconventional, but like I told you, as long as you're honest and upfront, then there's no harm in it." she then lightly poked her fingers over his chest. "Now... there's still the matter of those notes I mentioned...~"
Izuku closed his eyes and took in a breath, before smiling up at Nana with a determined look. "Please, teach me, Sensei!"
A Hero's job is manifold as they fight to protect others around them. But so too is a lover's job in keeping their partner happy and comfortable. Love is a powerful tool, one that needs to be wielded with immense caution and care.
Midoriya Izuku is one who wishes to make everyone happy. For that, he will learn, he will train, he will do everything in his power to make sure he could bring smiles to everyone who needed them, no matter the circumstance.
All so he could become... One For All Seasons!
