#bkdk #omegaverse #regencyau (CW: starts Dk//Hawks w/age gap, underage)
Alpha Bakugo Katsuki was a great fighter. He had to do it to survive after his parents passed away due to an illness than ransacked his village. There weren’t many upstanding ways to make enough money.

If you were an omega, you prostituted yourself. If you were an alpha, you fought in front of all the snooty rich people for their entertainment.
Katsuki hated it and he had his ass kicked a handful of times. But soon, no one could beat him.

3
By 15 years old, he had the entire country’s attention. Stronger and stronger fighters came from all over to try and end his long reign. And Katsuki stood up to each one of them. The rich bastards loved to bet against him but they always lost out!
4
Katsuki didn’t do it for the glory. He did it to survive! But damn, did he hate it when the wealthier brats came to watch him!
“That was so cool!”
“AH!” Katsuki screamed as he snuck out of his dressing room like he always did after a big fight to avoid the crowd.

5
An omega with lush green curls and bright green eyes wearing fabrics that could only be bought from the higher class beamed as caught him jumping out the window.
“WHO THE HELL ARE YOU STALKER?!” Katsuki barked. “HOW’D YOU KNOW I LEAVE THIS WAY?!”
“You always leave this way!”
“WHO THE HELL ARE YOU STALKER?!” Katsuki barked. “HOW’D YOU KNOW I LEAVE THIS WAY?!”
“You always leave this way!”
6
The omega pointed out. “I’ve been watching your past three fights and the way you take out your opponents is different each time! Sometimes it’s a quick knock off their balance! Sometimes you outsmart them! And sometimes you simply overpower them!”
7
He analyzed as his mouth moved so quickly, it made Katsuki dizzy! “You’re only my age so I can’t help but wonder, how do you-MMMMMM”
Katsuki slapped his hand over his mouth and shoved him into the nearest alley trash can.
“SHUT UP AND LEAVE ME ALONE!” He snapped.

“SHUT UP AND LEAVE ME ALONE!” He snapped.
8
“WAIT! KACCHAN!” The omega leapt out of the trash unphased and chased him.
“KACCHAN?!” Katsuki couldn’t believe the brat called him something so familiar!
“Sorry! That’s what all the grown ups called you in your younger years when they placed the bets!”
“KACCHAN?!” Katsuki couldn’t believe the brat called him something so familiar!
“Sorry! That’s what all the grown ups called you in your younger years when they placed the bets!”
9
“How long have you been paying to watch me, you brat?!” Katsuki growled.
“Not paying!” The omega put his finger up. “Sneaking in!”
“Huh?”
“My mom would never let me come see a violent underground fighting ring!” He chuckled. “She’s too protective!”

“Huh?”
“My mom would never let me come see a violent underground fighting ring!” He chuckled. “She’s too protective!”
10
“My allowance definitely doesn’t cover it! But the kids in the orphanage she runs heard the rumors about you and I just had to see it for myself! I overheard a couple of our donors talking about coming to see your next match and I’ve been sneaking in to watch you ever since!”
11
“Look, Deku!” Katsuki flicked him on the forehead.
“Deku?!” Izuku pouted. “My name is Izuku!”
“Fuck if I care! You’re useless to me! I don’t need fans! You know how I got so strong?! You know why I do this?! Cause I had to survive, idiot!” He shoved him to the ground.
“Deku?!” Izuku pouted. “My name is Izuku!”
“Fuck if I care! You’re useless to me! I don’t need fans! You know how I got so strong?! You know why I do this?! Cause I had to survive, idiot!” He shoved him to the ground.
12
“You said yourself, huh? You’re my age?! Yet you’re sneaking in to watch me almost die every day for your entertainment! Fuck off! And go home to your nice mom who actually cares about orphans!”
“I’m sorry! Wait! I didn’t mean to-” Izuku stood up and reached out for him,
“I’m sorry! Wait! I didn’t mean to-” Izuku stood up and reached out for him,
13
before Katsuki spit at his feet and got on his horse, leaving him in the dust.
At least he thought he did! He managed to spot Deku at almost every damn one of his next fights!
“Kacchan! That head injury looks bad! Please! Take this ice!”
“FUCK OFF!”

“FUCK OFF!”
14
“Kacchan! I made you some lunch! That was amazing the way you tripped that guy up by his clothes! Do you need some new clothes? I can-”
“Go away, Deku!”
“I fed your horse some brushed out her main for you!”
“DON’T TOUCH MOTHER OF MURDER!”
“Go away, Deku!”
“I fed your horse some brushed out her main for you!”
“DON’T TOUCH MOTHER OF MURDER!”
15
After months of trying to get rid of his stalker, Katsuki eventually like everything else bad in his life, got used to his company.
“Your house is nice and cozy.” Izuku made him some tea after Katsuki was the closest to losing he had been in a long time.
“Your house is nice and cozy.” Izuku made him some tea after Katsuki was the closest to losing he had been in a long time.
16
The only reason he couldn’t tell the omega to fuck off was because his throat had been ruthlessly stepped on by his opponent.
Izuku wasn’t completed dense and managed to gauge his mood as he patched him up and got a warm bath set up for him.

17
He wasn’t too chatty and wasn’t too annoying either. Dare the alpha think, it was actually nice having someone care for him after a long hard day.
“I apologize for overstaying my welcome but… you work hard and… I just think you should have someone work hard for you too!”
“I apologize for overstaying my welcome but… you work hard and… I just think you should have someone work hard for you too!”
18
Izuku smiled softly.
Katsuki groaned at the cheesy sentiment before pointing at a quill and an unused journal on the kitchen counter. The omega connected the dots as he brought it to him.
Katsuki took his time writing in big letters “DON’T YOU HAVE BETTER THINGS TO DO?!”

19
Izuku giggled before writing back in much smaller neat letters “I guess not!”
Suddenly the clock tower’s bell rung 6 times.
“Oh! It’s late! I better get back home before mom worries! Do you need anything else before I-”
Katsuki dismissed him with his hand,

Katsuki dismissed him with his hand,
20
and Izuku smiled softly at the gesture.
“Take care, Kacchan!”
After that day, Katsuki never saw him again. As much as he hated to admit it, the loss of his presence grated on him! Months and months of stalking and yapping and suddenly it was like Deku never existed!

After that day, Katsuki never saw him again. As much as he hated to admit it, the loss of his presence grated on him! Months and months of stalking and yapping and suddenly it was like Deku never existed!
21
Katsuki hated how his eyes searched the audience after every fight for those large green eyes. He hated how he snuck out the window to no one waiting for him! He hated how Mother of Murder was depressed all of a sudden as if Deku took care of her better than he ever could!
22
It weighed on him heavily. Suddenly, fighting just seemed pointless. He had enough money to not do it anymore. So why did he? Was he really so pathetic that he kept doing something he hated for the chance that he could see that omega again?!
23
In his short 15 years of life, Katsuki never felt so old. Just what was the point anymore?! Fight after fight, punch after punch, bloody noses and knuckles and broken bones he had to tend to himself. Damnit, without Deku he felt lonely!
And the one day while he was fighting,
And the one day while he was fighting,
24
he saw them.
Big round green eyes shining through a cloth that covered half his face. It was him! It was Izuku!
“DEKU?!” Katsuki leapt out of the ring, immediately losing the fight.
“AH!” Izuku gasped before running.
“OH NO YOU DON’T! GET BACK HERE!”

“OH NO YOU DON’T! GET BACK HERE!”
25
The audience gasped and whispered as he chased the omega out the nearest window.
“KACCHAN! STOP!” Izuku begged as he ran away.
“NO WAY! NOT UNTIL YOU TELL ME WHERE YOU’VE BEEN!”
“NOWHERE!” Izuku knocked a fruit cart over as if that could stop him!

26
Katsuki leapt in front of him and grabbed him by his cloak which was way fancier than anything he had ever worn before.
“Why’re you running, huh?! Finally found something better to do?!” The alpha sneered.
“Midoriya! There you are!” Katsuki froze at that voice.
“Why’re you running, huh?! Finally found something better to do?!” The alpha sneered.
“Midoriya! There you are!” Katsuki froze at that voice.
27
He would recognize it anywhere. The Duke of their land’s right hand man. Who bet the most out of anyone in the fighting ring.
Todoroki Touya.
“Running away again?” He shook his head. “What am I gonna do with you?”
“What the hell do you want with Deku?!” Katsuki growled.
Todoroki Touya.
“Running away again?” He shook his head. “What am I gonna do with you?”
“What the hell do you want with Deku?!” Katsuki growled.
28
“My question to you is what do you want with him Bakugo Katsuki?” Touya shook his head as he slowly approached them. “You’ve been fighting in that ring for years, without throwing a fight! But hell, I didn’t even notice him until you pointed him out? So what’s with you two, huh?”
29
“Nothing, Touya-San!” Izuku tried to break out of Katsuki’s grip on him and failed. “I’m just a fan! Like you… that’s all…”
“Give him here, Bakugo. And I’ll pay you the money you lost out on.” Touya held his hand before pulling it back. “Actually… I have a better idea!”
“Give him here, Bakugo. And I’ll pay you the money you lost out on.” Touya held his hand before pulling it back. “Actually… I have a better idea!”
30
He clapped his hands and laughed at his own genius. “I don’t know what your interest is in this kid. But I’m so tired of chasing him around! So how about your come and work for me? You never have to beat up for scraps again!”
“I’d rather eat shit than work for you!”
“I’d rather eat shit than work for you!”
31
Katsuki snapped.
“Fine then. Be ready to never see him again.” Touya leered. “I’ll just break his legs since you won’t help!”
“What the hell did you say?!” Katsuki was about to lunch at him before the Duke’s right hand pulled out a sword.
“KACCHAN!”
“Fine then. Be ready to never see him again.” Touya leered. “I’ll just break his legs since you won’t help!”
“What the hell did you say?!” Katsuki was about to lunch at him before the Duke’s right hand pulled out a sword.
“KACCHAN!”
32
“That’s enough, Todoroki!” A man with long black hair and drabby looking clothes rushed in with a horse drawn carriage.
“Aizawa-Sensei…” Izuku grumbled.
“I’m sorry he caused you trouble.” Aizawa apologized to Katsuki. “Get in, Midoriya. Before anyone else sees you.”
“Aizawa-Sensei…” Izuku grumbled.
“I’m sorry he caused you trouble.” Aizawa apologized to Katsuki. “Get in, Midoriya. Before anyone else sees you.”
33
“Yes, sensei…” Izuku tried to wiggle out of Katsuki’s grip but failed again. “Kacchan…”
“Aizawa, look at this! This fighter here is the best in the ring! And he got Midoriya under control in less than five minutes! Let’s hire him to keep him under control!”
“Aizawa, look at this! This fighter here is the best in the ring! And he got Midoriya under control in less than five minutes! Let’s hire him to keep him under control!”
34
Aizawa looked Katsuki up and down in a way that made the alpha flare his nose.
“Is this who you snuck out to see?” Aizawa questioned Izuku who looked away in shame.
“Get in, then Bakugo.” Aizawa demanded. “Before you get thrown in jail for kidnapping the Duke’s wife.”
“Is this who you snuck out to see?” Aizawa questioned Izuku who looked away in shame.
“Get in, then Bakugo.” Aizawa demanded. “Before you get thrown in jail for kidnapping the Duke’s wife.”
35
“What did you just say?!” Katsuki felt his stomach turn.
The Duke’s wife? He looked down to the tears prickling in Izuku’s eyes. He was his age. 15! And the Duke was young but he was way too old to be with someone like Deku!

36
“Now that you know our little secret, you have no choice!” Touya put his hand on Katsuki’s shoulder and pressed the cold steel of his blade against his back. “Come on. Your new job awaits!”
“I’m so sorry, Kacchan!” Izuku croaked as Touya forced them all into the carriage.

38
Katsuki knew the rich lived in big ass houses but he had never actually been inside one. The mansion Aizawa escorted them to was bigger than all of the city hall and the courthouse combined. It took them twenty minutes to get from the gate to the front entrance.
39
Touya kept his sword pointed at the alpha the entire ride while Izuku tried and failed to cry inconspicuously.
“Kacchan, I’m really-” Izuku tried to apologize again as soon as they entered the tall mahogany doors with solid gold knobs before Touya shoved him toward the stairs.

40
“Shut it, you! You don’t get to give him the grand tour after all the trouble you caused me! Get to your room! And you better stay there this time!” The right hand of the Duke seethed.
“Enough Todoroki!” Aizawa scolded. “Midoriya, leave it to me. Go.”
“Enough Todoroki!” Aizawa scolded. “Midoriya, leave it to me. Go.”
41
Izuku cursed to himself before bolting up the stairs, upset by the turn of events.
“You go too, Todoroki.” Aizawa instructed. “I’ll inform him of everything.”
“Ya sure? You know his reputation!” Touya pointed the sword to Katsuki’s neck. “He can take down ten of our guards.”
“You go too, Todoroki.” Aizawa instructed. “I’ll inform him of everything.”
“Ya sure? You know his reputation!” Touya pointed the sword to Katsuki’s neck. “He can take down ten of our guards.”
42
“I’m firmly prepared to handle that myself.” Aizawa easily whacked the sword out of Touya’s hands. “Go tend to the rest of your duties.” He ordered.
“Whatever…” Touya grumbled before walking away towards the opposite stair case that Deku used.
“Whatever…” Touya grumbled before walking away towards the opposite stair case that Deku used.
43
After Touya left, Aizawa turned to Katsuki and stared at him seriously. “My name is Aizawa Shota. This is Duke Takami Keigo’s civic house. He only comes here when he needs to meet with town officials to sign documents he can’t avoid doing in person.”
44
“This stair case leads to his chambers,” he gestured to the one Izuku ran up. “And this one leads to the offices and staff rooms.” He gestured to the one Touya went to. “I’m the house manager who keeps everything in top shape for any moment the Duke chooses to arrive.”
45
“Midoriya’s situation has obviously complicated things which I guess is where Todoroki wants you to come in. Bakugo Katsuki… a teenager yourself who fights in underground rings to survive… it’s irrational. But Midoriya himself is irrational. So it might work.”
46
“WILL YOU JUST TELL ME WHAT THE HELL IS GOING ON?!” Katsuki barked. “ISN’T THE DUKE ALMOST 30?! WHAT IS HE DOING WITH SOMEONE HALF HIS AGE?!”
“He’s only 22, and far far too irrational himself.” Aizawa explained. “Come with me this way, I’ll tell you everything.”
“He’s only 22, and far far too irrational himself.” Aizawa explained. “Come with me this way, I’ll tell you everything.”
47
Katsuki followed him toward the back of the home where his office was. The entire estate was opulent, and well decorated except for that office! It was plain, with all white walls, and had nothing but a poorly organized desk, a chair in front of that desk and a sleeping bag.
48
“Sit.” Aizawa sighed as he gestured to the chair.
“I’m fine.” Katsuki clicked his tongue.
“Suit yourself. As I was saying, the Duke, Takami Keigo tends to make quick rash decisions in everything he does. He is never in one place too long.”
“I’m fine.” Katsuki clicked his tongue.
“Suit yourself. As I was saying, the Duke, Takami Keigo tends to make quick rash decisions in everything he does. He is never in one place too long.”
49
“The last time he was here on business was four months ago. And that’s when he ran into Midoriya.” Aizawa explained, making Katsuki grit his teeth. Four months was the last time he saw Deku. “The Duke didn’t feel like waiting for me to pull up in his carriage after a meeting,”
50
“and he decided to walk home. Of course criminals used the opportunity and attacked him. While the Duke is a great fighter in his own right, he had no weapons on him and these men did. That’s when Midoriya rushed in and scared them off by saying he saw the police up the road.”
51
“The Duke Takami, irrational as he is, decided to ‘reward’ him for his bravery by bringing him here. Since omegas are always throwing themselves at him, he expected Midoriya to be the same. But I don’t think the kid even knew what he was offering until it was too late.”
52
Katsuki felt anger boil inside him as he realized what Aizawa was saying.
“Of course I do research on everyone the Duke brings home before they leave the next morning and draft papers for them to sign swearing them to secrecy. And when I found out Midoriya’s age,”
“Of course I do research on everyone the Duke brings home before they leave the next morning and draft papers for them to sign swearing them to secrecy. And when I found out Midoriya’s age,”
53
“I realized we had a big problem! The age of consent in Yuuei is 17. The royal family doesn’t give any leniency if crimes of this nature are found out! Which is why Takami immediately requested I draft a contract of marriage!”
“Huh?! How does that fix anything?!”
“Huh?! How does that fix anything?!”
54
“It’s essentially a legal kidnapping.” Aizawa confessed. “Midoriya agreed in exchange for his mother and the orphanage to be very well compensated. And his mother agreed without knowing what took place to instigate this marriage in the first place.”
55
“The plan is to keep him here in hiding until he’s of legal age before announcing the marriage to the public. An 18 year old omega marrying a 24 year old royal wouldn’t cause scandal three years from now.”
“So you want me to keep him inside for three damn years?!”
“So you want me to keep him inside for three damn years?!”
56
“I don’t want you to. You have to.” Aizawa leered at him harshly. “Listen to me, Bakugo. I don’t like this any more than you do. But if I go against the royal family, it’s not just my head on the line. It’s everyone I can’t afford to lose.”
57
“You’ve lived your entire life fighting for it. Here, you don’t have to fight anyone. You can live comfortably, you will always have food. And wine when you’re old enough. But if you betray the Duke, the pain you will be forced to endure will make you wish for death, understand?”
58
Katsuki didn’t like this feeling at all! His gut told him to run and get the hell out! But… he couldn’t leave Deku. It didn’t feel right!
“My horse.” Katsuki growled. “There a stable for her?!”
“Of course.” Aizawa sighed, glad he didn’t have to fight him himself.
“My horse.” Katsuki growled. “There a stable for her?!”
“Of course.” Aizawa sighed, glad he didn’t have to fight him himself.
59
After the awful introduction, Katsuki was given a tour of the estate, a key to his own room and then a team of five guards followed him home to pack up his things, and grab his horse. When the day was finally over, Katsuki was exhausted.
60
But he had a job he was accosted to do so before he went to test out his new bathtub that was in his room, he went to check on Deku.
He stood in front of the Duke’s large marble doors before pounding on it.
“Deku! You in there?!”
He stood in front of the Duke’s large marble doors before pounding on it.
“Deku! You in there?!”
61
Katsuki waited for a response… nothing. He knocked again. “Hey! Open up! Don’t make my new job harder, damnit!”
The door slowly opened as Izuku peaked out from behind it. “You took it?”
“Didn’t have a choice.”
“I’m sorry…” Izuku moped as he opened the door fully.

“Didn’t have a choice.”
“I’m sorry…” Izuku moped as he opened the door fully.
62
“I hoped you wouldn’t see me… I…” Izuku teared up and Katsuki realized his eyes were swollen from crying all day. “I just needed to watch you because… watching you up there always gave me hope! I’m sorry! I know it was hard for you! And now…”
63
“Stop yer crying.” The alpha chuffed. “Do you know how freakin’ pissed I was that you just up and disappeared on me after annoying me non-stop?! Well you can’t escape me now, Deku!” He grinned. “Now you have to see me!”
“R-right…” Izuku brightened. “I guess I do…”
“R-right…” Izuku brightened. “I guess I do…”
64
“Ya better not try and sneak outta here then!” Katsuki roughly grabbed him and carried him over his shoulder.
“AHH! KACCHAN! WHAT ARE YOU DOING?!” Izuku blushed as the alpha threw him on the bed.
“I’m your jailer now, Deku!” He grinned evily, making Izuku laugh.
“AHH! KACCHAN! WHAT ARE YOU DOING?!” Izuku blushed as the alpha threw him on the bed.
“I’m your jailer now, Deku!” He grinned evily, making Izuku laugh.
65
“You play the villain roll really well, Kacchan! Hahaha!”
Katsuki didn’t realize how much he missed his smile until then. Damn… his chest ached from how much relief he felt that he now knew exactly where Izuku was… and he didn’t find something better than him.
“KACCHAN?!”
Katsuki didn’t realize how much he missed his smile until then. Damn… his chest ached from how much relief he felt that he now knew exactly where Izuku was… and he didn’t find something better than him.
“KACCHAN?!”
66
Izuku gasped as the alpha collapsed to the floor in exhaustion, finally able to sleep after the longest four months of his life.
