Side A

 

 ---

 

Beep! Beep! Beep! Bee-

A hand whaps at the blaring alarm clock and sends it to the ground as the hand retracts under the blankets. The small bundle under the plush covers lay still for a moment more before throwing them off excitedly. The little girl has a large smile on her face as she hops out of bed and rushes to get ready for the day. She brushes her teeth aggressively, knowing that her parents instilled good hygiene habits into her since she was able to do it on her own, brushed the knots and tangles out of her dark green hair, and washed her face.

Once she is freshened up, and dressed, she bounds down the stairs and into the kitchen, quietly packing the lunch her parents prepared for her the night before into her backpack. She takes out a piece of paper and a handful of assorted crayons and scrawls a message for her parents. She leaves it on the table, the message reading, ‘See you at school later! I love you!’, surrounded by hearts of different colors.

The girl grabs a handful of strawberries and drops them into a snack-sized Ziploc baggie before heading towards the front door. She doesn’t bother telling her parents that she's leaving, usually muttering a quiet "I'm going now" as she knows that the life of pro-heroes is a tiring one, especially one of their stature. It’s routine after all and routine means, letting her parents sleep as much as they can.

She skips happily to school, knowing today is Parent Visit day so she gets to see her family a little later. The elderly lady living next door notices her and she waves like she does every morning.

“Ah, Ame! Good morning!”

“Good morning, Kinami!”

“Off to school?”

“Mhmm!”

She makes her way over to Ame and hands her a flower picked from her own bushes.

“Do your best then!”

Ame smiles brightly and waves goodbye to her before resuming skipping down the street towards school. She pulls out a small music player from her pocket and plugs the earbuds into her ears, playing her favorite song on the way to school.

This is just routine.

It is routine when she turns the corner and is greeted by a cat that lives in the neighborhood, offering it pets. It is routine when she said good morning to the mailman delivering the morning mail and working his route, and it is routine when she passes by the corner store and the man behind the counter sneaks Ame a piece of candy that he received that morning.

It is routine when she turns a corner and see her school ahead of her, classmates and teachers ahead of her, chatting happily with parents or friends they walked with.

It is not routine when she is grabbed all of a sudden by her arm and forcefully pulled into a dark alleyway, a cloth held over her mouth. She struggles against him, trying to scream but her vision starts to become fuzzy, causing the noise around her to turn into a faint, high pitched buzz. She could hear the music player clatter to the ground at the mouth of the alley, still blaring her favorite song.

“Ah the Symbol of Peace’s daughter. How lucky of me!” The man breathes into her ear, but she's barely able to hear him. Even when she tries to strain her ears to make sense of the garble that is coming out his mouth, it only serves to exhaust her more. Though, she does manage to make out one thing.

“Days and days of watching and studying and I finally got you! You’re too easy to predict! Can’t believe his daughter was this easy all along!”

Despite her efforts, Ame’s head lazily rocks back on his his arm. Her vision goes in and out, barely making out the man put a hand on the brick wall in front of her. A swirling vortex forms and she makes one last effort to struggle, scream, cry but nothing comes out, even as he throws her in, effortlessly.

---

A beep is heard when a boy with dark green hair presses a button on his watch, effectively stopping the timer, recording his time.

“Deku!”

He turns and sees his brunette-haired friend, catching up to him and stopping the timer on her own watch as well, panting heavily. They both struggle to catch their breaths, even as they each down a water bottle.

“Did you beat your time?” she asks him, pointing the open end of her bottle towards him and he nods, a proud smile on his freckled face.

“Yeah! I actually managed to shave a few minutes off! What about you, Uraraka?”

She looks down at her watch and gives him a triumphant smile as well, pumping her fist into the air.

“A couple minutes better than the last one!” Ochako starts jumping with glee and high fives her best friend, proud of the progress the two of them are making. They worked so hard to make sure they get better, faster, stronger together and it’s starting to pay off now that there are results.

“Oh! I was wondering when the two of you would finally show up!” the chipper voice of their friend causes them look over to where their spectacled friend is, waving at them.

“Iida, that’s not fair! You’re fast to begin with!” Ochako whines and he only laughs.

“As true as that may be, I am nowhere near my top speed. Running with the both of you during these mornings is proving to be of huge benefits, though.”

Izuku smiles and laughs with his friends, watching the exchange between the two and finding it cute. He looks around and sees a few of his classmates finally catching up to them. Looking in the direction past their Class rep, he sees the other half of the class laying back in the grass and catching their breaths. This isn’t something that their teacher told them to do but, rather, something the class thought of collectively. Not only are they training, but also building a stronger bond together.

Izuku’s wandering green eyes finally land on fiery reds and he feels his heart jump into his throat, looking away. He tries but fails to erase the sight of his childhood friend’s sweaty body, dressed in the black tank top he always wears when training. It’s almost criminal with how good of a look it is on him.  He hates this crush he has for the other, wanting to only view Kacchan as a rival rather than a lover. At least one is plausible while the other is impossible.

Izuku blushes, conveniently lucky that they were just on a run. He can easily excuse the redness as being tired and sweaty.

When did it become like this? When did it become ‘I want to beat you’ to ‘Beat me off’? He internally slaps himself for that thought. He sighs heavily and wipes the sweat from his forehead with his arm. No need to think about him, just focus on getting better.

“Oooh, I think I know who you’re thinking about.” Ochako’s teasing causes him to jump and quickly recompose himself, denying any and all claims of what she’s talking about, though her eyebrows wiggle knowingly.

“No! You got it all wrong! I wasn’t thinking about anyone, I swear!” Izuku sputters, trying his best to defend himself from his all-knowing friend. She laughs and winks, nodding her head towards a certain blonde’s direction.

“Deku!" the sudden shout of his name makes him jump and slowly turn his attention to Katuski. "What’s your time?!” the sweaty angry blonde stalks over towards him, while their classmates only sigh and shrug. No amount of team building will ever change anything between the two, they've concluded.

“It’s uhm…” He fiddles with his watch, hands effectively shaking as he struggles to find where the time is recorded. Katsuki is face to face with him in no time though and Izuku just stares dumbly at him.

“Doesn’t matter. I got here before you did, and it’s gonna stay that way!” he shouts, pressing a finger onto his chest with a significant amount of pressure, to the point where it hurt.

Izuku winces but toughens up before him, meeting the glare with a look of determination, full of challenge and fire. He can see the twitch Katsuki has in his eyes.

“That may be true but, I’m gonna keep working hard with everyone!”

Katsuki clicks his tongue and rolls his eye, stalking away.

“Annoying as always, you shitty nerd. Just don’t get in my way!”

Izuku releases a breath he didn’t know he was holding, shoulders slumping as Katsuki walks further away from him and towards the dorms. A few others rush over to Katsuki and give him their usual stern talking to about lighting up, which falls on deaf ears. Ochako jumps towards him, hands on his shoulders, breaking him from his thoughts. She gives him a sympathetic look.

“Hey, ignore him. Let’s head back and get ready for class soon!”

He nods and begin to jog with the rest of their class back towards the dorms when a very loud whoosh sound comes from behind them, effectively stopping the class and gaining their attention. A vortex appears from thin air, causing the students to activate their quirks and take a defensive stance. Something like this shouldn’t be happening here. Izuku watches the vortex carefully, ready to act quick if and when anything decides to slither its way through and onto school grounds. They picked the wrong school and group of students to mess with.

He imagines a horrible villain, or one of the League of Villains to show up through the vortex. What ends up appearing is a small girl, unconscious and being spat out of the vortex rather violently. His body is moving before his mind is to catch her before she hits the ground.

“Midoriya, be careful!” Someone shouts behind him, but he doesn’t look back, just looking down at the small bundle in his arms, sleeping. He’s never seen her before and she doesn’t appear to be any threat to them, but he can't be too careful. He looks up at the vortex, expecting for something to follow her out but slowly, it shrinks until it eventually disappears. The others slowly drop their defenses and run up behind him to see who the child is and mumble amongst each other, wondering what to do or who she is.

“That's it? A little runt like her? It could be a fucking cheap trick…” Katsuki growls and this confirms the fears of a few of their peers but Izuku doesn’t believe that, not at all. Ochako carefully takes the yellow backpack off of the girl, Izuku finding it strangely familiar.

“Let’s look through her belongings. She must be in elementary school, so they must have that little card stating who they are. You know the one, right?” Ochako asks, gaining the support of Tenya.

“Ah, yes! I remember the one. The cards they're required to carry around should they go missing. It would have her information and everything we need to identify her.”

The students nod in agreement as Ochako looks through the bag. She feels a bit guilty, invading the little girl’s privacy like this, it feels very un-heroic like.

As she looks for the card in the bag, Izuku feels movement in his arms and he looks down, seeing the young girl stirring and finally, awakens. She rubs the sleep and crud from her eyes and slowly turns her attention up at him.

“Hi there.” Izuku greets her gently, not wanting to spook her.

She stares up at him, shock evident on her face. She looks around, the shock forming into confusion. Suddenly, her face shrews up, tears forming in her large, green eyes.

“P…papa…”

Time seems to freeze as they register what she just called Izuku, who’s only 16 years old. Not the ideal age at all to be anyone’s ‘Papa’.

“Papa!” She cries louder, clutching at his tank top tightly and crying into it, practically bawling.

“Deku…”

He turns his attention from the sobbing girl, clutching onto him tightly, to Ochako. The others look to her as she shakily holds the small girl’s id card in her hand.

“Midoriya Ame. 6 years old. In case of emergency, contact: Midoriya Izuku.”

The revelation is hard to take in and Izuku feels his blood turn cold. The dark green hair, the yellow backpack, bright green eyes? No wonder it seems familiar.

“This…this is a joke, right?”

“Let me see that!”

Tenya snatches the card from Ochako's trembling hands and reads it over carefully before his eyes widen and he nearly drops the card from shock.

“She…She was born 20 years from now.”

Momo takes the card and a few of their classmates gather near her, reading it for themselves.

“This is a joke, right? It has to be joke! There’s no way this is even possible!”

Izuku has no idea what to do, not with the questions his classmates are throwing at him and not with the little girl clutching onto him like her life depends on it. She must be so confused, that had to be it. There’s no way he would ever have a child, he’s never even had sex before! He wants to question the young girl, but he thought better of it. She's clearly distressed nad he doesn't want to further confuse or distress her. For now, his questions will have to wait.

Ochako digs deeper through the bag, looking for more clues, sheets of construction paper bounded together by yarn tied in a bow fall out and drift towards Izuku. The cover only confirms the craziness and the impossibility of all of this. Written in black crayon, the title is messily scrawled at the top.

‘Why I love my Papa!’

He bends down, little girl still in his arms, and picks up the makeshift book, observing the photo glued on the front more closely. He's met with a very grown up Izuku smiling brightly with the little girl sitting on his shoulder, smiling as brightly as him, almost like a spitting image.

“We…We have to get Aizawa-sensei.” Denki suggests, though with hesitance in his voice. They don’t want to do anything that would put the girl in harm’s way but there is nothing that could be done with just them.

The others nod in agreement and collectively decide to hurry and get ready for their classes, jogging back to the dorms. Izuku stands with shaking legs as he carries Ame in his arms, unsure of what exactly to do and it doesn't seem like she was going to let go of him. Ochako gathers Ame’s belongings and slings the backpack over he shoulder, walking side by side with him, who, no doubt, would need so much support right now.

There’s no room to joke or talk, the air tense at the revelation before them. It’s quiet as they enter the dormsm his classmates throwing glances and side eyes at Izuku's way as he walks past everyone. Ame crying and wailing had calmed down significantly, reduced to whimpers and hiccups. He manages to open the door to his dorm room and enters with Ochako following in and lays Ame carefully on his bed.

Ochako closes the door and once it does, Izuku nearly collapses, only to be caught and stabilized by his friend.

“Deku…”

“What do we do?”

“What?”

Izuku is as pale as a ghost and for once, he isn’t muttering insistently like he usually does. He truly is at a loss for words at the revelation that this little girl could potentially be his daughter 20 years in the future. Despite all of this, his heart feels warm at the thought that he was able to have a precious little girl, who loved him so dearly and it’s evident that he loved her dearly too.

Izuku sighs heavily and finally stands, with the support of Ochako and the wall behind him, thanking her.

“Let’s…Let’s get ready for class.” Ochako is hesitant at first to leave him but she nods and jogs away, finding there is only so much she can do.

---

When Izuku returns to his room to grab his bag, he finds the door is open, a crowd gathering and Aizawa-sensei inside, kneeling before Ame, who keeps asking for him.

“When did-?”

“Iida ran to the school to get Aizawa-sensei to come here instead. He said something along the lines of not needing the rest of the school to know about this…” Toru tells him, and he nods, finding that it made a lot of sense. Having the whole school find out about his apparent daughter will only get twisted and eventually, reach the ears of the media. That’s the last thing he wants and he imagines the school wants.

He manages to squeeze his way through the crowd and the little girl brightens up when Izuku comes into view, practically lunging toward him and clutches his pant leg.

“See mister, this is my papa, he can answer all the hard questions!” she proudly claims, pointing up at Izuku, and if the situation wasn’t so serious, the class would find her love for her father adorable as can be. However, this is a very serious situation.

Aizawa looks over at the flustered Izuku and sighs heavily.

“Explain.” it isn’t a question, but a demand.

One by one, starting with Izuku, the students begin to recount what happened and what they saw, minus the presence of Katsuki, Shoto, and Eijirou. Once he got their accounts, Ochako hands Ame’s schoolbag to their teacher, who proceeds to take it, as well as taking the id card handed to him.

He observes everything silently, firstly telling the rest of the class, minus Izuku and Ame, to head to class for the time being. They hesitate for a moment but nod nonetheless, offering Izuku a quiet ‘good luck’ and walk away. Both Tenya and Ochako give Izuku a reassuring squeeze on his shoulders before walking away as well.

It’s quiet in the room and Izuku is lucky Ame is so well-behaved as she doesn’t say anything to disturb the strange man looking at all of her stuff or constantly asking questions. He must be a pretty good dad. The only move she makes is the nudge on his hand and he takes her small hand into his, holding it tightly. They both need the support as Izuku figures all of this is new, strange, and scary to her as well.

“This definitely isn’t the first time something like this has happened.” Aizawa confides to his student and this sends Izuku’s mind reeling. What? This has happened before?

“What do you mean, sensei?”

Aizawa sighs heavily and crosses his arms.

“It’s best that I discuss this with the school board on how we should proceed. This is a very serious matter and her present will alter heavily if anything from our present changes. Go and head to class, I'll take care of Ame.”

He feels Ame’s hand tighten in his and looking down at her, he sees the fear and confusion in her eyes, not wanting to be away from her presumed father.

Of course, she knows that the current Izuku isn’t her father at all but, he’s the only familiar face amongst the sea of stranger faces and she needs the support of someone familiar. Izuku kneels before her and covers her hand with the both of his.

“Ame, Aizawa-sensei is going to take care of you now while I go to school. Can you be good to him, for me?” he speaks with her gently, wanting to comfort and reassure her that she'll be ok. All he can do is try his best, to hope that his future-self instilled strength in her.

Ame holds his gaz and sees the pleading green eyes of her father before nodding slowly, letting go of Izuku’s hands and shyly walking up to Aizawa. He looks over to his student and nods.

“Join the rest of the class, she’ll be ok.”

Izuku nods and waves goodbye to her before jogging out of the building and towards the school.

---

He can hear the sounds of his classmates speaking wildly, wondering what the heck is going on and how this is happening. When Izuku slides open the door of his classroom, the talking ceases almost immediately and he quietly, nervously, shuffles over to his desk.

It remains quiet for a bit before Tsuyu speaks up.

“Midoriya-chan, Is Ame-chan with Aizawa-sensei?”

He nods and looks around the room, seeing all of them sharing in his nervousness and hesitation, apparent on their faces. They aren't familiar with this kind of thing, time travel that is, and are unsure of how to even proceed. Should they even be interacting with her at all? Won't that mess things up for not only her but them? 

“Aizawa-sensei, he…said this kind of thing happened before.”

“What?” it’s collective and sudden and only brings about more questions. Only Tsuyu says anything positive in light of the situation, in hopes of lifting the mood.

“So, if it’s something that happened before, doesn’t that mean that they already know how to fix it? Then Ame-chan can go back home with the Midoriya-chan of the future.”

Eijirou smiles and nods in understanding.

“Hey, that makes sense! So, the situation isn’t as dire then, right? Things will be ok!” though not by much, this does somewhat lift the mood in the class and they’re rowdier than ever. Now that the seriousness is temporarily out of the way, Mina, Toru, Momo, and Ochako begin to coo over how adorable Ame is, clinging so tightly to Izuku and overall, being a good girl. The class gathers over to where he sits and begin to praise the future him, to the great annoyance of Katsuki.

“Huh, makes you kind of jealous, though doesn’t it?” Denki states, gaining the nods of agreement from a couple of their male classmates.

“Does it? Didn’t really think of it that way. Now that I do though, Midoriya, you’re super lucky to have a good kid like her!” Hanta states, giving him a friendly nudge on his shoulder with his fist. Izuku turns from tense to sheepish. He nervously scratches at the back of his neck.

“I...I shouldn’t be getting any of this praise, it wasn’t really…me, you know?”

Though he has to admit, he is pretty lucky to have a well-behaved and adorable daughter. Ame looks almost identical to Izuku, to the cute freckles across her nose and cheeks, though not as heavy as his own, green eyes as bright as emeralds, dark green hair that’s fluffy and messy like his, though it’s longer and not as curly.

It does make Izuku wonder…

Is there a mother in the picture?

He didn’t see any picture of a woman amongst Ame’s things and when Ame looked at the class, she didn’t react to any of the girls in his class quite like how she reacted when seeing him. Is he even sure if there’s a woman in the picture?

Izuku blushes a bit at that.

Is there…is there another man in the picture?  

Katsuki grinds his teeth in annoyance as he leans back in his char, feet propped on the desk, and is only further provoked when Eijirou points his thumb in his direction, smirking.

“Kinda makes you think what kind of dad Bakugou would be, huh?” the class erupts into laughter and Katsuki turns his head at them, angry and annoyed beyond belief.

“Shut up, shitty hair! I would make a great dad for runts like Deku’s!” He shouts, and the girls coo even further at the proclamation, to which Katsuki yells at them to shut their traps.

Katsuki walks over to where Izuku is sitting and grabs at the collar of his uniform, wrinkling the material as he nearly pulls him out of his seat.

“Ya hear that, Deku!? My kid would be better than yours!”

Izuku feels a sense of protectiveness over his future daughter and gets riled up, grabbing tightly at Katsuki’s wrist.

“Kacchan’s kids will be amazing like you but Ame will be the greatest!”

Watching the two argue about their future kids bring smiles and laughs out of the class, finding the exchange adorable. Even if they’re too young to think about this kind of thing and obviously, are wanting to be pro-heroes first and foremost, the prospect of having a family is humbling. To have a child where you can pass on your knowledge and know-how and watch them grow into someone who could potentially make a difference.

But again, they’re too young to think about this kind of thing.

The door to the classroom slides open and Ame is standing there, hand in hand with Aizawa, smiling when she sees Izuku and then smiles even further when her eyes land upon the blonde who’s grabbing Izuku.

“Papa! You found daddy!”

Revamp completed 11/12/24

lmao I love this fic and think so fondly of it but going back and rewriting/revamping makes me cringe like "man who let me write this!?" Anyway, I hope it's much more enjoyable and easier to follow!

This is also to say that characters may be considered OOC to the latest chapters of my hero as I've stopped keeping up with it. Consider this right before the Eri stuff so when they're much younger and not as jaded.
