Summary
Kirishima stayed planted in the chair, lungs burning like he'd sprinted the whole way home. His cum was already turning sticky across his stomach and between his fingers. His cock gave one lazy twitch against his thigh, finished but not really done. He raked a hand through his hair, trying to shake some sense back into his skull, when the soft chime hit.
A private message window popped open in the corner of the app.
From X.
𝗲𝗫𝗽𝗹𝗼𝘀𝗶𝗼𝗻: 𝙃𝙤𝙥𝙚 𝙮𝙤𝙪 𝙡𝙞𝙠𝙚𝙙 𝙩𝙝𝙚 𝙨𝙝𝙤𝙬, 𝙍𝙚𝙙.
Kirishima stared at the line until the letters blurred a little. His thumb hung over the keyboard, and he started typing before he could talk himself out of it.
𝗥𝗲𝗱 𝗔𝗹𝗽𝗵𝗮: 𝗬𝗲𝗮𝗵. 𝗟𝗶𝗸𝗲𝗱 𝗶𝘁 𝗮 𝗹𝗼𝘁. 𝗧𝗵𝗮𝗻𝗸𝘀 𝗳𝗼𝗿 𝘁𝗵𝗲 𝘀𝗵𝗼𝘄.

Summary
Working with Izuku Midoriya was supposed to be simple.
Do the job. Build the gear. Keep it professional.
Instead a quirkless support specialist omega named Katsuki Bakugo finds himself caught in the orbit of a rage-baiter alpha who smells like comfort, looks at him like he’s already chosen and flirts with devastating sincerity...and who breaks his gear way too fast.
Picnic not-dates, bright laughter and fierce desire start to change their relationship, and Bakugo has no idea what to do with himself. The problem isn’t Izuku’s attention, it's that Bakugo wants it -- and once this alpha falls for this omega it’s only a matter of time before something gives.

Summary
A canon-compliant My Hero Academia retelling with A/B/O dynamics.
Second genders are subtle, but expectations are not.
As U.A. High unfolds exactly as it does in canon, Eijirou Kirishima—an alpha who has never felt strong enough—and Katsuki Bakugou—an omega who refuses to be seen as weak—find themselves drawn together through rivalry, respect, and an unbreakable bond.Kiribaku-centric. Canon events, rewritten through instinct, suppression, and choice.

Summary
Izuku is 21 and unmated. Hes quite a strong alpha and is part of clan Shimo, but none of the omegas appeal to him in that clan, hence why hes unmated and why he finds himself running away from them with gentle warning snarls while they whine behind him. He doesnt think much of it, just thinks 'alright i guess ill be unmated till the end of my days 'until a blonde, red eyed omega with a sharp mouth and intense personality sweeps him up..

Summary
Kirishima hasn’t heard from his mate, Katsuki, in nearly five years. The system insists everything is fine—he’s been compensated, the files say he exists, the heroes say he’s safe—but Kirishima knows something is wrong. His omega is missing from the official records, absent from the world he trusted. Everyone tells him he’s imagining it, that his grief is misplaced, that he’s overreacting. When he finally finds Katsuki, the truth is horrifying: voice stripped, body twisted by cruel government experiments, conditioned to live in constant heat. The world tells him he’s imagining it, that his grief is misplaced—but Kirishima sees the shattered shell of his mate. Consumed by sorrow, rage, and devotion, he vows to protect Katsuki, to reclaim the life stolen from him, and to show his omega love and safety in a world determined to erase him. He would kill for love. The world calls him delusional, but Kirishima sees the broken shell of his mate. Consumed by rage, sorrow, and unshakable devotion, he vows to protect Katsuki, reclaim the life stolen from him, and give him love, safety, and comfort. He would kill for love, endure unimaginable pain, and get back at those who did this to him.

Summary
The omega was up and ranting again about one of the newest members of the Debate team, pacing back and forth while his roommate sat calmly on the couch.
Shoto chortled, tilting their head to one side and finally glancing up from their phone.
“What a fucking cunt, I hate these big-dicked SHITHEADS who wander in and think they can whore around at every turn. I heard he’s in one of the fucking frats too, so its no surprise he’s such a-” He froze.
His own frustration was overpowered, slowly, another smell wound itself around him. Katsuki’s hands fell from his face, looking around with slight puzzlement.
Something in his gut shifted, and ease flooded him. He glanced towards the source, watching him with a subtle force. They patted the spot next to them.
“Come here,” they beckoned him.

Summary
Kirishima swallowed hard. After years tangling with each other, Kirishima was well-aware of the prince’s secondary gender. The last time they’d met, Kirishima had almost been captured by Sheriff Todoroki. That hadn’t gone well. During his (rather sexy) escape, Kirishima had spun around Prince Bakugou, leaning in just close enough to brush his lips against the prince’s golden collar.
Then he’d slipped past and vanished into the night.
Ah, what a night that was.
He still tasted the prince’s scent on his lips.

Learning to be by KingHugin

Summary
Katsuki had learned that sometimes being a Hero meant putting one's needs on the back-burner, and to be honest he was more okay with that than most. Easier to deflect questions when he had a ready answer; being a Hero came first.
He wants nothing more than to be the best he can be, secondary gender by damned. That is until the only brand of suppressants he could stomach suddenly became discontinued. Now his body is forcing a heat he hasn't asked for, making decisions for him. He’s left wondering if it would be better suffering in silence at home, buried under a nest that will never feel like enough. Or giving in to his friend's request to try out the one place he never wished to visit even if he was dragged there kicking and screaming.
How far Katsuki willing to go to seem normal.
Being an Omega sucked.
(this fic started out with me just wanting to write some good ol A/B/O porn, and well it spiraled. You're welcome?)

Summary
Cuando todos se graduaron inmediatamente el mundo estaba enfocado en las nuevas integraciones a héroes profesionales, había grandes promesas que ya se especulaban y susurraban en el aire, pero entre todas esas personas no apareció una tan polémica y esperada, ni siquiera sus compañeros sabían nada de él, se desvaneció por completo por al menos un año completo, debutó un año más tarde, Jeanist no parecía darle tanto bombo y fuerza como esperaban pero claramente aún le apoyaba.
Habían pasado unos años de eso y en una pequeña reunión con otros héroes la mayoría jadeó con sorpresa cuando el rubio entraba con una niña en brazos que no pasaba los cuatro años, usaba una mascara que la protegía muy bien, pero algo en ella les llamaba la atención, no solo por su mera existencia, el saber que Bakugo tenía una hija era una locura, pero la mayoría enloqueció cuando la niña corrió para abrazar a Endevor apenas toco el piso.

Summary
“Your eyes are silver,” Shouto said, simply. “And I’m guessing mine are gold.”
The omega bares his teeth. He only comes up to just past Shouto’s shoulders, as most people do, but the alpha gets the feeling that his aura normally makes him seem taller than he actually is. “And what of it, fucker?” His voice is gruff and cruel.
“Normally, that’d mean we’re a fated pair.” he responds, bluntly, wondering if his omega knows a kinder tone.
He doesn’t. “Oh yeah, asshole?”
“Uh… yeah.”
Todoroki Shouto doesn’t know when exactly it happens or why, because he’s high off the adrenaline of the moment at that point, but then he and his omega are on the floor engaged in a fist fight that would go down in UA history.
Yeah. Fated Pairs are normally unconventional.

[Shouto and Katsuki are fated on their first day at UA and wreak havoc on the entire student body + hero world because of it]

Summary
Bakugo Katsuki thought he could handle everything alone. As an omega, he spent years balancing hero duties with careful use of suppressives, keeping his instincts tightly controlled. After a patrol incident lands him in the hospital, a doctor’s recommendation for a heat partner leads him to ask the one alpha he trusts—Kirishima—to move in.
Living together forces them into close contact, and the boundaries between care, desire, and trust blur. Bakugo must learn what it truly means to rely on someone, confront his fears, and embrace who he is—while preparing to return to the hero work that defines him.
~~
Eijiro Kirishima thought he knew what it meant to protect others, always charging forward, strong and dependable. When Bakugo asks him to move in after a patrol incident, Kirishima faces a new responsibility—navigating the vulnerabilities of someone he trusts.
Living together pushes him to confront his own fears and understand Bakugo in ways he never expected. Through shared challenges and quiet moments, Kirishima learns the balance of care, trust, and desire—and what it takes to protect someone he deeply cares for.

Summary
Bakugou Katsuki doesn’t owe anyone anything—not the alphas who pay for his body, not the dead-end job that barely keeps a roof over his head, and definitely not the past he walked away from three years ago.
Survival means strict rules, numb detachment, and never letting himself believe kindness comes without strings. But one unexpected client breaks every pattern: paying triple without demanding more, offering food before touch, and looking at Katsuki like he’s a person instead of a service. It’s unsettling. Dangerous.
Worse, it makes Katsuki wonder what it would feel like to stop fighting for once.
