Pro Hero Alpha Katsuki likes to keep his work and private life separate. Mainly to protect his quirkless omega husband at home. In this day and age of heroes, it was common to have secret identities. So by day he was Great Explosion Murder God Dynamight, but

his husband simply knew him as ‘Kacchan’. They had grown up together but went their separate ways when Katsuki went to hero school and Izuku continued his studies elsewhere. Then they reunited when Katsuki saved Izuku from a villain by chance.

He was still in his hero costume so he had to pretend like he didn’t know him. But then he stepped away, changed immediately and pretended like he was passing by and saw the whole thing.

“You almost died, you damn nerd!”

“K-Kacchan!” Izuku gasped. “You saw that?!”

The rest was history. They married and mated quickly and now they lived a quaint life in a cozy apartment. Izuku was under the impression Katsuki worked an office job while he stayed home and kept the house clean. Katsuki valued that privacy above all else,

so he never told his friends about his husband. He had a few hero friends who knew his secret identity but they had no idea he was married.

One day, Pro Hero Pinky, real name Ashido Mina, found out.

“This is a bad idea.” Kaminari Denki protested.

He, Mina, Kirishima Eijio and Hanta Sero were making their way to Katsuki’s apartment while he was on a mission.

“It’s for his own good.” Mina said seriously. “What was Bakugo thinking marrying someone quirkless! If I found out, anyone can find out!”

“We should let him be happy!” Denki groaned. “He’s done a great job of hiding him so far! We have no business interfering!”

“We should at least warn the guy what he’s up against.” Ejiro cautioned. “Believe it or not this is being heroic. Bakugo put this omega in grave danger.”

“We as heroes put our lives on the line every day AND our happiness for the peace of everyone else.” Sero added. “It only makes sense for us to be with other heroes. Or at least someone who can properly defend themselves!”

“This the one?” Eijiro started at the apartment door.

“That’s it.” Mina informed him.

“Kinda surprising.” Denki smiled at the floral reef on the door and the cutesy welcome mat on the floor.

“Here goes nothing.” Eijiro knocked on the door.

“Who is it?” He heard a sweet voice question.

“We’re heroes of this town!”

“Red Riot, Cellophane, Pinky, and Chargebolt! We need to ask you some questions.” Eijiro introduced them.

Izuku quickly unlocked the door and swung it open excitedly. The heroes were surprised to see such an adorable Omega look at them with stars in his eyes.

“It’s really you!”

He beamed. “Wow! C-come in! Don’t mind the mess! I slept in today while my husband was out.” He laughed nervously. “Oh! Pardon my rudeness, I’m Midoriya Izuku and I’m such a huge fan!” Izuku led them to his living room and frantically pranced around for pillows for them to sit on

Eijiro was surprised at all the photos of Izuku and Katsuki around the apartment. To anyone who didn’t know, they looked like your normal every day couple.

“Woah! Check this out!” Mina whispered as she pointed at a photo of Izuku and Katsuki as kids.

“You guys can sit here and make yourselves at home while I get some tea.” Izuku blushed. “Then I will answer any questions you have!”

“Thank you for your hospitality!” Kaminari bowed guiltily. He was shocked Katsuki was married to such a kind person.

The four sat around and waited for Izuku to return.

“Guys, we should just leave them be.” Kaminari suggested once again. “They clearly have a happy home. This is wrong.”

“No. What’s wrong is putting him in harms way like this.” Eijiro said.

“He’s definitely different than I thought he would be.” Sero nodded. “He looks like he wouldn’t hurt a fly much less defend himself. This guy is so painfully nice, I wouldn’t be surprised if Katsuki faked his entire personality to get him!”

“Oh come on!” Denki rolled his eyes.

“They’ve known each other a long time, it seems.” Mina grumbled. “How long has he been hiding him?”

“I’m back!” Izuku entered carrying a tray of tea. “I really can’t believe you’re here in my living room. I wish my husband was home! He’s a big fan of you guys too!!”

He babbled as he served each one of them.

“Yeah, about your husband.” Kirishima cut to the chase before sipping his cup. “How much do you know about the guy?”

“How much?” Izuku blinked. “Everything!” He beamed. “Kacchan’s the best!” Suddenly it dawned on him.

“He’s not in trouble, is he?”

“Izuku.” Mina smiled. “Can I call you that?”

“Um, sure.”

“We see that you have a happy life with Bakugo, but… it’s not safe for you.” She informed him. “He’s actually a hero, like us!”

“Great Explosion Murder God Dynamight.” Ei clarified.

“We read on your file that you’re quirkless.” Sero went on.

“Not that here’s anything wrong with that!” Kaminari interjected.

“There’s nothing wrong with it but there is something wrong with your husband not informing you of all the circumstances of your life together!”

Kirishima went on. “As heroes, we recommend separating. It’s not good for you two to be together.”

Izuku looked sad and Kaminari felt angry that he was part of this. He was such a sweet guy.

“It’s your choice at the end of the day! We can’t make it for you!”

“But we strongly recommend you sever your bond and find someone who’s not going to hide their life from you.” Mina added.

“I appreciate your concern.” Izuku said after a beat. “And thank you for informing me, but I already knew about Kacchan’s real job.” He giggled nervously.

The heroes paused and looked at each other as Izuku grabbed the empty tea cups and brought it to the nearby kitchen. “Kacchan doesn’t know I know so I’d appreciate it if you don’t tell him. He’s very proud of himself for how well he hides things but he’s actually very bad at it.”

He began to wash the cups while they looked at him in bewilderment.

“I know all of the risks that come with dating a hero as amazing as him. It’s fine if you look down on me or him for mating me but I wouldn’t change anything.” Izuku smiled at them.

“We don’t look down on you!” Kaminari leapt up to protest but apparently a little too quickly. “Woah…” He stumbled back and plopped back on the pillow as a dizzy spell hit him.

“Of course you do.” Izuku said as his voice echoed in the room. “All heroes do.”

“It’s natural, right?” He said as Mina suddenly passed out on the table. “The strong look down on the weak. Heroes are meant to protect but when they see themselves as God,” Ei passed out next.

Kaminari wondered if he was seeing things as green electricity surrounded the omega.

“They don’t notice the devil staring at them right in the face.” Izuku smiled wickedly as he floated in the air with black tendrils surrounding him before Kaminari felt the world go black.

He suddenly woke up in Mina’s living room gasping for air.

“Where am I?”

“Here.” Mina blinked in bewilderment. “Gosh, where had the day gone? Now it’s too late to go over Bakugo’s.”

“Guess we’ll have to go tomorrow?” Eijiro felt his head point. “Shit. I have a hangover. Did you spike those beers or something, babe?” He asked her.

“I don’t remember drinking beer.” Sero wracked his brain. “How did we all fall asleep?!”

“I don’t know.” Denki felt like something was off. But he couldn’t quite place it. “I think this plan is a bad idea guys. We should just… leave it alone?”

Izuku purred as he sat in his husband’s lap after he returned from a ling day of work.

“How was the office today?” Izuku questioned before showering his face with sweet kisses.

“Lame as always.” Katsuki said before catching his mouth and sticking his tongue down his throat.

“I’d rather do this all day.” Katsuki tackled him, making Izuku giggle.

“Another successful rescue from Hero DynaMight!” The reporter on the TV spoke. “The number one hero has been making record time, keeping the peace even better than All Might did!”

“That’s a big claim.” Izuku mused. “I love DynaMight as much as the next person, but better than All Might?”

“You don’t think agree?” Katsuki cocked his brow.

“I don’t know. I guess the crime rate has been much lower since he took the number one spot.”

“But maybe that’s because he’s much much scarier than All Might with that temper of his.” Izuku laughed.

“Yeah? Well I’ll show you scary! Come here!” Katsuki layed him over his lap and spanked him.

“KACCHAN!” Izuku blushed.

“While DynaMight sure is great at keeping crime down”

The other reporter spoke. “I can’t help to feel a sense of unease. Afterall, the leader of the underworld, Deku, could still be out there. That terrifying power of his would give even DynaMight a scare. His terror on Japan was unmatched,”

“yet his activities all but ceased suddenly two years ago.”

“Oh. I remember that. I was so worried about picking our honeymoon destination because villains were so scary back then!” Izuku laughed.

“Yeah, but that coward seemed to runaway after I- after erm- Dynamight debuted.”

“I’m really glad things are safe now.” Izuku grabbed his arm. “Maybe we have DynaMight to thank for having such a peaceful life together. Afterall, if he didn’t save me, we wouldn’t be here.”

Katsuki grabbed his face and kissed him gently before shutting off the TV.

“Yeah. A life I wouldn’t trade for the world.”

They kissed and snuggled before Izuku’s phone started to buzz.

“Ah. I gotta take this. It’s my knitting club.” Izuku giggled. “I’ll be back.”

“Be back soon, I need to blow off some steam.” Katsuki said suggestively.

“I’ll try!”

Izuku giggled before stepping outside to the balcony and shutting the door. “What do you want?! I’m busy.” He answered the phone coldly.

“Deku, we need your help.”

“I told you. I’m done, Ingenium. It’s your underworld now.” He said firmly.

“Come to the base. It’s urgent.”

Izuku rolled his eyes and ended the call. He really hated being summoned away from the life he worked so hard to get.

“Kacchan.” Izuku walked in with watery eyes. “I’m so sorry, I have to go to an emergency meeting for my knitting club. They entered a fair last minute!”

“I’ll drive you. It’s dangerous to walk by yourself.” Katsuki stood up.

“No need! Todoroki-kun is already on his way to pick me up! Let me just gather my supplies really q-” He froze as Katsuki suddenly bent him over the couch.

“How much time do you think we have?” He whispered

“Mmm…” Izuku squirmed. “5 minutes.”

“That’s all I need.” Katsuki chuckled as unbuckled his belt. At least his evening wasn’t completely ruined.

Uravity, Shoto, Ingenium and Izuku all sat in the corner of the library with their knitting materials.

Uravity had bruises on her face and her hair was singed. “Do we really have to actually knit?”

“It’s soothing.” Izuku said as he made a scarf. “You should try it. Might be a better outlet for your anger.”

“Deku.” Iida whispered under his breath.

“This is serious. We have a major operation underhand and we need you to keep DynaMight distracted!” He seethed.

“I told you, I’m not to interfere in my husband’s job.” Izuku said coldly. “You’ll have to finish the operation without my help.”

“What’s wrong with you?!”

Uraraka chastised. “You used to be ruthless. You hated heroes. Didn’t let any of them boss you around and now you wanna play good little housewife while he does THIS to us?!” She gestured to her burnt hair.

“I finally got what I always wanted.” Izuku said.

“A happy, peaceful life where I can be who I am and no one will judge me for it. Kacchan loves me for me. Even if he finds out about all this, which he won’t, he will still love me. And I love him. And because I love him, no one will touch him.” Izuku smirked.

“Not unless they want to die. Don’t you see what that means? The villains fear me so they fear him. Crime has gone down because I want it to go down. If I wanted it to go up, it would go up. There is only peace because I want peace. I have control over all of it.”

“Heroes. Villain. They are all people born with power and too much ego to know what to do with it. And me, someone born powerless. A powerless, male omega has complete dominion over all of their pathetic lives. All because of All Might.” Izuku giggled. “Because he trusted me.”

“But rest assured on his grave. His Will was realized. He became the symbol of peace. But me? I am peace. And you can’t have peace without also having control of chaos.” Izuku said as he finished his hat. “Do you think Kacchan will like how I look in this?” He beamed.

“Yes.” Shoto nodded before snapping his picture.

“Todoroki, stop.” Uraraka rolled her eyes.

“Perhaps that’s what you think.” Iida stood up before snatching the hat away. “But chaos is far more powerful than you realize!”

Suddenly the “staff” locked all the doors. The “patrons” stood up. And everyone surrounded them.

“You’re really going to try this?” Izuku sighed.

“You WILL help us.” Iida demanded as Izuku grabbed his cell phone.

“Yeah. Hold on just one second.”

Everyone looked as uneasy as Izuku suddenly began to cry.

“Kacchan! Kacchan help! Call a hero! The library is being attac-”

Iida snatched the phone and threw it on the floor, breaking. “Have you no shame anymore?!”

“You have 5 minutes Iida.” Izuku grinned. “Try your best.”

Katsuki burst into the library in full costume along with his hero friends 5 minutes later.

“Oh my god… what happened here?!” Mina was shocked by all the blood, dead bodies and broken furniture.

“IZUKU!” Katsuki screamed. “IZUKU! BABY! WHERE ARE YOU?!”

“Kacchan…” Izuku whimpered. “Help…”

Katsuki ran and opened a closet where Izuku was cradling his friend, Todoroki Shoto. “He’s barely breathing. We have to get him to a hospital!”

“Izuku…” Katsuki grabbed him. “It’s me. It’s me. I’m here.”

“Y-you?! You’re- a hero?”

“We can talk about that later. Come on. Let’s get your friend to a doctor!”

Kaminari looked around at all the carnage as everyone else tended to Shoto. Katsuki wrapped Izuku in a blanket and held him close to comfort him as they waited for the paramedics. But something was off.

“What happened? Did you see who did all this?” Katsuki whispered.

“I-Ingenium and Uravity… b-but they got away.” Izuku sniffled. “It was awful Kacchan! So scary!”

“Well I’m here now.” Katsuki held him tight. “And your friend will be fine, okay? You did good. You stayed alive.”

Katsuki held him tight and as Izuku’s eyes met Denki’s across the room everything came swarming back to him. The tea. The tendrils. The wicked smile. The electricity.

His face paled in realization as Izuku shakily out a bloody finger to his lips.

He knew that meant one thing. He said a word? He was dead.

Later that night after a trip to the police station, Katsuki tended to his mate in their nest. He covered him in his favorite covers and kissed him tenderly over and over on his scent glands.

“I’m sorry. I should have gone with you. I’m worried they somehow found out who you are.”

“I don’t think so. They weren’t really targeting people. Just killing for the sake of it. How is that there’s such evil in the world, Kacchan?” Izuku sniffled.

“I don’t know, baby,” Katsuki rolled him on top of his chest and caressed his face gently. “But where there’s evil, there’s peace.” He kissed him. “You taught me that. When I saw you again, and rescued you that day, I knew I would whatever it takes to make sure you were safe.”

“That’s why I didn’t tell you. I didn’t want you to ever be scared anyone would hurt you.”

“Well you did a very good job at hiding it. I had no idea!”

“Really?!”

“Kacchan’s amazing!” Izuku beamed and Katsuki kissed once more.

“More amazing than All Might?”

“Hmmm… almost there.” Izuku teased him. “But only because you have me.”

“Right.” Katsuki grinned. “Because you give me something to fight for every day.”

“Exactly.” Izuku laced their hands together. “So together, let’s let everyone have a peaceful life.”

“Yeah. Together.”
