Summary
Novarch City. Five rings, five cages.
Captain Shoto Todoroki has spent his life serving the Novarch City Police Department upholding the laws that keep the city running. When a rebel ambush turns into a one-on-one fight with Dynamight, the most notorious mechanic-turned-saboteur in District Five, Shoto’s world tilts on its axis.
The rebels take him alive. He expects brutality. Instead, he finds something far worse: a glimpse of truth.
Smoke and static follow Shoto back to his polished world. His loyalty is questioned, his leash pulled tighter, but the memory of what he saw in the undercity refuses to let go. And when he crosses paths with Katsuki Bakugo again they ignite something that wasn't meant to burn, lines blur, and an unlikely alliance begins to form.
Together, they will challenge a system that was never meant to bend — and if they fail, the city might burn with them.
OR:
Dystopian BNHA Cyberpunk AU. Police Captain Todoroki isn't just kidnapped, he's forcefully drowned in the ugly truth and finds himself falling for the rebel who started it all. Enemies-to-lovers, rebellion, found family, action, angst, slow-burn romance, and a dash of hope. -
Moments That Feel Like Home by Interstellarcomet, KeikoAkai

Summary
A story of a life time told in fragments — thirty-five years of Shoto and Katsuki stitched together through warmth, grief, softness, chaos, and everything that makes a life shared worth living. These aren’t in any particular order. They’re memories: some long, some short, some sharp, some blurred at the edges, some loud, some whispered, all of them shaping the life they built together.
From their first, messy kiss to the quiet middle-aged mornings full of tea, cats, and aching backs, to grief shared, to joy rediscovered — this is the long slow miracle of growing up together and choosing each other again and again and again — this is how they grew, how they healed, how they loved.
A retrospective.

Summary
“What if I tell you I’m married instead?” The other returns with a honeyed voice and Katsuki is ready to throw his head back and groan. He doesn’t. He contains it by his limitless willpower, because he’s just amazing like that and the supposedly nameless man doesn’t seem to notice his internal struggles.
He just keeps smirking instead, shamelessly obnoxious now. He’d be damned if he gave up just now. Oh no. He’s not a quitter for fucks sake. “Then I would call it bullshit, no sane partner would let you wander around all by yourself looking like that.” it’s risky, sure, he can admit that, but so far this pretty boy hasn’t told him to fuck off or slapped him across the face? No risk, no fun, huh?
“If I was your husband, I would be right by your side, making sure people keep their greedy hands to themselves. Really irresponsible.” and the other chuckles which is tugging on Katsuki's heartstrings for some god damn reason. God. He’s going to fuck a married man and he’s obnoxiously thrilled to do so.

Shoto asks for a one-night-stand and Katsuki knows how to deliver, because he'd be damned if he can't fulfill Shotos every wish

doggystyle by underfallingflowerpetals

Summary
Now, Katsuki’s a giant wolf pinning him to the floor, and instead of feeling terrified about it, Shouto wants to press his thighs together.
Katsuki noses at his neck with his snout, follows the line of his carotid, and Shouto’s clit throbs so hard he whines. And then he’s nuzzling his jaw, licking at it with a rough tongue, and part of Shouto wants to open his mouth and say please.
But instead—
Instead, he says, “Do you, um, want to fuck me?” because he’s never been one to do anything by halves.
Or: Omega Shouto lets Katsuki knot him in wolf form. But make it soft.

Warmth by underfallingflowerpetals

Summary
Shouto wonders if it's a wolf thing. The, uh, breeding instinct. Or if it’s just a Katsuki likes Shouto thing. Maybe—maybe both? But still, when Katsuki talks to him like that, like Shouto is his so intrinsically and inescapably that only a fool would dare question it—
Slick trickles down Shouto’s thighs, slips out of him around Katsuki’s half-swollen knot. “Katsuki,” he whines, fighting the urge to unwrap his tail from Katsuki’s thigh and put it in his mouth just for a familiar comfort to cling to through the best and worst pleasure of his life.
Or: During their first time, Shouto gets a little overwhelmed.

Summary
“You’re mine,” Katsuki hisses now, voice raw, filled with unmistakable desperation, need so palpable Shouto’s scared he’s going to slick right through all his clothes even if he’s nowhere near his heat. His alpha wants him. His alpha needs him. His alpha needs—
This. The part where Shouto takes him in, in, in. Shouto. Because while Katsuki might be borderline feral from his rut, Shouto’s the only one he’s looked at, the only one he’s pulled close by the waist, the only one he’s wanted to touch and scent and, apparently, fuck. Knot. Keep.
Shouto nods, tilting his head so Katsuki has an easier time reaching his scent gland. “Yes,” he says, eager for it. “Yeah, okay. I’m yours. I’m your omega.”
Or: Shouto helps Katsuki through an unexpected rut while undercover.

Knotty Mouth by Inatodo (Phinphin)

Summary
Shouto has to admit that when the idea first entered his head, he dismissed it as not only a bad idea, but also a sign that he needed to stop ogling Inasa during their workouts lest the horny police came to arrest him for horny crimes. Because honestly, the idea of Inasa knotting his mouth should not be turning him on.
