Hello! I had this idea and absolutely had to write a oneshot for it in honor of Father's Day for our favorite underground hero! Just a warning: this is a purely self-indulgent parental fic with loads of fluff and absolutely nothing else. Shouta adopts Eri, Hitoshi, and Shouto because I really want him to and this is my fic. I hope you all enjoy!

I do not own My Hero Academia.

"SHOUTA!"

Shouta rolled over and covered his head with a pillow. The voice had come from his living room and he could hear the loud footsteps coming toward his bedroom. There was a fist pounding on the door a few seconds later.

"Shouta, you need to get up!"

"Go away, 'Zashi," he grumbled. "How the hell did you even get in here?"

"It's almost noon!"

He shot up into a sitting position and rubbed his eyes. He checked his phone. Sure enough, his friend was right.

I need to make lunch for Eri. Has she even gotten dressed for the day? Is Hitoshi even up? Well if he wasn't—wait, weren't he and Shouto supposed to paint with Eri today? They both promised her they would. Did Shouto come down from his room already….

The infinite questions rattling in Shouta's brain ceased when the door flung open.

"What the hell—"

He was cut off when a pair of black sweatpants hit him in the face and fell down in his lap. His brow furrowed when he realized they were his favorite pair that he'd just worn a couple days ago.

I haven't had a chance to do laundry yet.

"I found these folded for you on the couch and figured you would probably want them. Anyways, you have ten minutes to get ready before I drag you out of here!" Hizashi announced before slamming the door shut.

He shook his head and got up. Grabbing a loose, long-sleeved shirt from his dresser, he quickly put on the dark ensemble and shoved his feet into the closest pair of shoes. He trudged into the bathroom. He did a double take when he saw his reflection, noting how his eyes didn't seem as bloodshot as they normally are. The cold water he splashed on his face dashed any remnants of sleep.

"Five minutes, Sho'!"

He rolled his eyes at Hizashi's voice. After brushing his teeth and combing his fingers through his hair, he finally left the bedroom. He froze when he passed by Eri's room and found it empty. He peeked into Hitoshi's room only to find it empty as well. The living room was surprisingly quiet. He walked in and paused when he noticed the two stacks of laundry neatly folded on the couch. A brief glance told him those were his and Eri's clothes. His friend stood near the kitchen and had his eyes glued to his phone. His eyebrows rose when he saw the man wearing a simple pair of jeans and a light yellow short-sleeved shirt. His long blond hair hung around his shoulders, slightly frizzy with a few tangles here and there.

"Where are Hitoshi and Eri?"

The blond perked up with a grin. Shouta barely lifted a hand in time to catch his campus and dorm access cards.

"Let's go!"

Hizashi grabbed his arm and started dragging him to the door. He yanked his arm back.

"Wait, where are—what the hell? Put me down!"

The voice here didn't hesitate for a second before bending down and picking Shouta up in a fireman's carry. He laughed, his quirk slipping a tad and slightly shaking the room.

"Sorry, Shouta, but we're in a bit of a rush today. Eri's with Shinsou and Todoroki right now, so there's no need to worry."

"But my students—"

"Most of them went home for the weekend, remember? Besides, I've already asked Ishiyama to keep an eye on the few that are still here. They'll be fine!"

Hizashi had no problems carrying him through the halls and out of Heights Alliance. He was grateful the few remaining students weren't around in the common area; or, if they were, they were wise enough not to laugh or comment.

"Where are you taking me?" he asked, his friend not even phased by his attempts to get down.

Damn hero work.

"I can't tell you! I don't want to ruin the surprise!"

"You know I hate surprises, so you'd be doing me a favor."

"You can't change my mind!"

Shouta groaned and let his head drop. The two didn't say another word until Hizashi had carried him to the staff lot. He glared at the car and opened his mouth, but his friend beat him to it.

"You and I both know I'm not afraid to shove you in the trunk. Just get in."

Despite the laughter, there was no missing the underlying threat. Shouta plopped down in the passenger seat. He rubbed his eyes as Hizashi got in and started the car. His eyebrow twitched when the car didn't move. Huffing and turning in his seat, he tensed when he saw his friend smiling at him, and not with his over-the-top Present Mic smile. He fought not to squirm under the voice hero's gaze and faced forward.

"Didn't you say we were in a hurry?" he grumbled.

He could feel the gaze linger on him a moment longer before Hizashi finally put his hands on the wheel.

"Yeah, we are," the blond conceded. "Just out of my own curiosity: what day is it, Sho'?"

"Sunday?"

Shouta couldn't stop the question in his tone.

Am I missing something?

Hizashi laughed again, this time careful not to let his quirk slip. He drove out on the streets of Musutafu, and Shouta couldn't even begin to guess where his best friend was dragging him off to.

*break*

"Is your side good?"

Shouto looped the string around his fingers one last time before pulling it taut. He looked up at the tree across from him and nodded. Hitoshi, straddling the branch, was tying his last knot. The two couldn't help their relief when the banner actually stayed put. The purple-haired teen swung himself off the branch and landed with a grace that was eerily similar to their homeroom teacher turned adoptive father. Shouto blinked before following suit.

"It's about time, you two! They're probably almost here by now!" Nemuri teased.

Shouto tensed, but slowly relaxed when Hitoshi snorted and shook his head.

"As if you can talk. How long has it taken you to put up that dartboard?"

The somnambulist rolled her eyes. Securing the mount to the tree and hanging the dartboard, she stepped back and admired her handiwork. It dropped a second later and she hung her head.

"Dammit," she swore under her breath. "Could you two help Eri finish her card?"

As if the little girl could hear her all the way from the picnic table, she came running toward the two students. Glitter trailed behind her with every step.

"Hitoshi! Shouto! I finished my card!"

Shouto crouched down and took the paper in his hands. Four stick figures were on the front. His brow furrowed when he saw the figure with red and white hair. He opened it, careful not to rip the paper when it stuck together. Giant letters covered the entirety of the paper with glitter strewn over it in reckless abandon. He nearly jumped when he felt an arm on his head.

"I have to say, Eri," Hitoshi said, looming over him, "you're definitely an artist. Aizawa will love it."

As if the girl's smile couldn't get any brighter, she grabbed Shouto's hand and dragged him toward the table.

"We have to put it with the others!"

Shouto couldn't quite stop the slight upward quirk of his lips. Eri had wasted no time warming up to him the second he was introduced to her as her new brother just a couple months ago. She'd probably seen him around Izuku and that alone probably comforted her.

They stopped at the table, a dark green table cloth draped over the wood. A couple bags and an assortment of Tupperware containers sat on top of it, along with Shouto and Hitoshi's own cards. He picked his up and opened it. Unlike Eri's there wasn't anything colorful about it.

But it was filled with his handwriting.

"Have you found a card yet?" he asked.

Hitoshi looked over his shoulder and joined him. His heart sunk when he realized he'd already picked one out. His newly adoptive brother followed his eyes, scanning over the infinite number of cards.

"I've looked through so many," he said, fighting to keep the annoyance out of his voice, "but nothing seems to…."

He couldn't even get himself to finish. Hitoshi's eyebrows rose and he plucked a card out and handed it to him.

"Try this one," he suggested.

He opened it.

"It's blank?"

"You can write whatever you want in it. You can't seem to find what you're wanting, so you're better off writing it yourself." Hitoshi checked his phone. "We should probably find Yamada and Kayama. They have to be out of the craft section by now."

Hitoshi was right. Once he started, he couldn't quit writing until he'd taken up all the space on the card. He took out a folded sheet of paper from his pocket and tucked it inside, his thoughts not even fitting with all the blank space the card provided. His eyes bounced between the card and presents.

It's only been two months. Will Aizawa-sensei even like it….

"He's going to love it, Todoroki."

The art history teacher shook him out of his thoughts. He turned around, seeing a softness in her gaze that he'd never seen during class. He nodded before putting his card in the envelope and setting it back on the table.

*break*

He checked his phone. Three minutes until the final bell. A quick glance up at his class told him they were still struggling with their worksheets. Browsing through his messages, he read the text one last time.

"Not" Shouta's Kid: Can Shouto and I stop by after classes today?

Not that he could really forget the text. Hitoshi had only reached out to him a couple times in the eight months Shouta had adopted him, and Shouto had only been out of Endeavor's custody for a couple months now. Despite his insistence for the two of them to ask him if they needed anything, they'd yet to take him up on his offer.

He stood up and slammed his hands on the desk.

"HEY, LISTENERS! Why don't you all take those worksheets home and have them ready by the next class?"

The relieved sighs drowned out the final bell ringing, and the room evacuated quickly. He plopped back down in his chair. Picking up his pen, he returned to his grating. He perked up when the classroom door opened again. He stood when his two guests entered.

"Shinsou! Todoroki! What can I do for you?" he asked with a wide smile. "Based on your last exam scores, I know neither of you are needing help with English."

Hitoshi didn't hesitate stepping further into the room, and Shouto briefly stopped before following until the two stopped in front of his desk. The two shared a glance before Hitoshi spoke up.

"Do you need any help at the radio station?"

His brow quirked and he leaned back a little.

"I honestly never thought either of you would be interested in radio work..."

He trailed off, realizing both of them seemed to be avoiding his gaze. Shouto crossed his arms and looked at the ground. Hitoshi never had any problems talking to him when he helped Shouta with his training. He's taught the two for almost a year now. Neither of them would be this shy...

He straightened instantly.

"Wait...do you two need money?" Hitoshi bit his lip before nodding. "Hey, I know Aizawa isn't the easiest man to approach, but if you guys needed anything he would—"

"We need to get something for him," Shouto interrupted.

Hitoshi nodded again.

"Father's Day is in a few weeks, and Aizawa's made a lot of sacrifices for us. We wanted to get him something, and I know Eri was wanting to make something for him, too. It seems like your radio station constantly has events going on, so we'd though we'd ask you if..."

He sat back down in his chair and took off his glasses. He couldn't even hear what the kid was saying, if anything. He buried his face in his hands, forcing himself to take a deep breath.

"Is everything all right?" Shouto asked.

He couldn't stop the smile from spreading across his face, and not Present Mic's smile.

"You're completely right." He forced himself to take another deep breath when his voice hitched. "I've been friends with Aizawa nearly half my life, so it means the world to me that you truly understand everything he's done for you. I'm very impressed that you two were willing to work for that money, but that won't be necessary. I'm more than happy to help out with this."

He may not have commented on it, but he'd forever treasure the light in the boy's eyes. They clasped their hands and bowed.

"Thank you, Mic-sensei," Shouto said, and he could practically feel the graditude radiating from the boy.

"It's no problem, but please call me 'Yamada'."

"We're here!" Hizashi exclaimed, putting the car in park. He reached behind him to the backseat and threw a cloth at the dark-haired man. "Put this on!"

"This isn't logical. I already know where we are."

The blond looked back out the windshield to the trees and nearly empty sidewalks. The two of them hadn't had a chance to come out to this park in quite some time.

"Humor me."

Shouta huffed and tied the blindfold around his eyes. The voice hero jumped out of the car and helped his friend out. He adjusted the cloth over the man's eyes.

"Are you sure you can't see anything?"

"Hizashi—"

"Let's go!"

Shouta didn't flinch when a pair of hands clamped down on his shoulders and steered him away from the car. Hizashi was surprisingly considerate, warning him to watch his step, not running him into anything.

How long have we been walking? Where could we possibly be—

They stopped, and Shouta could feel his friend untying the blindfold. He blinked once it was removed, eyes widening at the sight before him.

"Surprise!" Eri yelled, sitting on Hitoshi's shoulders.

His three young charges stood under a massive banner reading "HAPPY FATHER'S DAY!". Nemuri's old dartboard was mounted on one of the trees, and he could see a picnic table set up just beyond the two trees. A camera shutter turned his attention to the somnambulist.

Nemuri's in on this, too?

"Seems like you forgot what day it was, Shouta," she chuckled under her breath.

That got Shouto to cover his mouth, but Hitoshi didn't even bother hiding his laughter. He hesitantly approached the three kids. Eri frowned.

"Do you not like it?" she asked.

He carefully lifted her off Hitoshi's shoulders and into his arms.

"I love it, Eri. I have to say, I'm very surprised."

That's an understatement.

"We thought you might like a day away from the dorms," Shouto explained.

"We've got plenty of food for the day," Hitoshi continued, gesturing toward the picnic table, "and we should even have leftovers for the next few days. Kayama and Yamada helped us make it this morning. It's probably cold by now, but I guess it's a good thing we've got a human microwave with us."

Shouto actually cracked a grin at that. Shouta looked between the two boys.

"Did you also do laundry this morning?"

They both nodded. He rubbed a hand down his face.

These kids...

Eri wiggled out of his arms and dropped to the ground. She grabbed his hand a heartbeat later and ran toward the table.

"You have to open your presents!" she yelled.

The others followed. Eri insisted she sit next to him, Hitoshi and Shouto sitting across from them.

"There was no need—"

Hitoshi practically shoved his and Shouto's present into his arms.

"Please, just open it."

Shouta would be lying if he said he didn't appreciate the black blanket with white paw prints dancing over the fabric, or the mug Eri had painted for him. The two boys looked to Hizashi and Nemuri before handing over the last bag. His eyebrows rose when he ruffled through the paper.

Is this a book?

He opened it and his heart stopped. A picture of him and Hitoshi took up the entire page. Neither of them were looking at the camera. He was wearing a suit, but Hitoshi had gotten away with just wearing his school uniform. He recognized the background instantly.

This was taken at the courthouse the day the adoption papers finally went through. I know Hizashi and Nemuri insisted on being there, but did they actually get a photo...

Sure enough, there was a similar one of him and Eri on the next page. They even got one of him and Shouto after he gained custody of the kid couple months ago. The picture was a little blurry, but he was surprised someone had gotten one at all.

He couldn't stop his grin as he flipped through the next few pages. Hitoshi, Shouto, and Eri seemed to have taken it on themselves to fill a few more.

"There's not many," Eri said sadly, but she perked up instantly, "but there's plenty of room to add more!"

"And today's as good of a day as any to add some!" Hizashi said, grabbing Nemuri's camera.

Shouto and Hitoshi moved stand behind their adoptive father and sister. Much to everyone's relief, Shouta didn't put up ounce of resistance.

And if Shouta genuinely smiled in every photo they took on their first Father's Day as a family, the pictures would simply get added to the album without another word.

Well, there it is! I hope this was a nice ball of fluff to add to your day. This was my first time writing Shouto, so I hope he was as in-character as he could be in this situation. Writing Hizashi and Shouta interacting was a lot of fun, so I hope you enjoyed that too!

I have a lot of fanfics planned for this fandom, and I can't wait to get to it! I'm really hoping that's sooner rather than later, but we'll see!

Until next time,
