“kacchan? 10-101, do you copy?” izuku was panting, his body aching from fighting off the little crew of villains he and katsuki had been called in to fight off together.

nowadays it was rare that he and his mate were called in together for work.

after himiko was born six months ago, izuku and katsuki made sure that one of them was always with her.

izuku wanted to see his strong amazing omega make the most badass comeback from his maternity leave, so ‘hero deku’ took a hiatus.

and things were //amazing//.

himiko was the best baby as soon as she was born. so beautiful and sweet and sleepy—being a stay-at-home sire was a breeze.

katsuki was coping almost too well, no noticeable postpartum distress (and izuku was keeping an eye out).

anxiety seemed to be the only one.

the only one to cripple and terrify his mate.

anxiety of something bad happening to their daughter while he was working, or of him dying in the field, or of izuku dying, or them being kidnapped, or sids.

izuku always reassured him, and katsuki would always calm down after.

but today was, again, a rarity. katsuki had been on his normal patrol when he got an SOS text from their agency.

/Hero Dynamight is cornered, please send any available heroes to the following area:/

izuku had never called his mom so fast to come over to watch ko-ko.

he didn’t care about the possible reprimand he could face about putting himself in danger too—

all he cared about was kacchan. saving him, because he would always save him. no matter the circumstances, or the cost.

he’d arrived on the scene first (because of course he had) and discovered it was a group he remembered katsuki talking about. low grade, strong quirks, but poorly organized.

it was easy enough to take them down, but when he got to where kacchan had last been seen…

he wasn’t there. the villains that had cornered his kacchan were already unconscious, but kacchan was nowhere to be found.

he tried the comm again, “kacchan? i need your 10-101 confirmation, do you copy?”

silence was his only reply, and a growl was building in his chest.

he got in touch with hero support after one minute of no response.

“it appears hero dynamight’s communication device and tracking are offline. his last known location was… ‘hero boba cafe’?”

though the support representative sounded confused, izuku immediately understood.

he quickly released the villains to on-duty heroes and officers and raced to their home.

the hero boba cafe was the boba shop the lived right above, specifically choosing that apartment during kacchan’s pregnancy to both upgrade and accommodate for his cravings.

izuku checked his phone and saw a text from his mom.

/Katsuki just came home. He’s pretty distressed, but he didn’t want to inconvenience me, so I left but I’m just waiting downstairs if you think I should go back up./

his mom was //amazing//.

he sent back a quick reply thanking her and asking her to head home, and please text him when she makes it in safely.

it takes him no time at all to get to their apartment, go through security and biometrics and carefully, slowly walk into their den, their home.

“kacchan?” he called out quietly, listening and searching for any signs of distress from either his omega or his pup. his instincts on high alert because it wasn’t like kacchan to not respond, especially not with izuku.

after toeing off his boots, he went into the nursery.

the lights were off, the sound machine on, their baby fast asleep in her crib, and kacchan was sitting crisscross on her rug, right across from her.

his shoulders were shaking and izuku immediately noticed that his heat resistant gloves were on—

something he hadn’t work since /high school/.

izuku slowly and carefully joined his mate on the ground, sitting close enough for their thighs to touch, but not making any sudden movements past that.

“hey sweetheart,” he whispered, not wanting to overwhelm kacchan or wake ko-ko.

he was met with sniffles, only heightening his concern.

“i was worried when you didn’t report back,” he explained, “i heard you were cornered and i…i’m sorry if my going to the scene upset you, kacchan. you know how i can get,” he tried to tease, but kacchan wasn’t budging.

katsuki was looking at his hands, his bottom lip quivering, “th-they…” he shook his head, tears falling onto his cheeks, “it’s s-so stupid, but they said… the most //horrific// shit,” he grit out, and it was clear that it was a struggle to keep quiet.

izuku frowned, reaching out a hand to rub soft, soothing circles on the small of his back. he opened his mouth to ask what, or if katsuki wanted to talk at all, but his omega beat him to it.

“‘i hope you and your baby //die// in a fire that you cause from your n-negligence.’”

izuku’s eyes widened, “kacchan, that’s…!”

kacchan wasn’t done.

“‘i hope you and your baby choke and suffocate, and that your h-husband dies trying to save you, you s-stupid omega whore.’”

izuku was seeing red as he heard the words fall from katsuki’s lips.

but he had to reign that in. he had to stop the growl that was emitting from his body.

but most importantly he had to //comfort// his kacchan.

slowly, he turned & coaxed kacchan to look at him by tilting & holding his chin. his free hand went to one of katsuki’s gloved ones.

“look at me, katsuki,” he murmured, searching those beautiful red eyes that he had begged the universe, more than once, to open, or look at him.

“you are the best dam for our ko-ko, you take such //such// good care of her. you are so gentle, and patient, and careful with her.”

“there has never been a doubt in my mind that you are the best at everything you do—and you prove me right again and again with everything you do for her. the way you make sure she’s safe, and happy, and healthy. the way you remind me to take care of myself after a long day.”

he took off the gloves, one by one, and laced his fingers through katsuki’s shaking ones.

“and that villain was //wrong//, and a coward,” he added, his voice laced with poison, “the most incorrect thing he implied was that i couldn’t save you and ko-ko.”

emerald eyes burned with an intensity he hasn’t felt since kacchan’s heart was ripped from his chest. “i would burn the world down to save my family,” he told him, and he meant it.

katsuki hiccuped on his quiet sobs, “y-you… you really promise that she’s s-safe with me?”

that intensity flickered out and was replaced with a softness he only ever really showed to kacchan. he squeezed his hands three times, “i swear on my life, kacchan. you are the //best// and strongest and sweetest dam and mate and partner in the world.”

and when he offered a smile, katsuki slowly relaxed enough to let izuku lead him out of their daughter’s nursery, where his alpha cooked for him, loved on him, and made sure //he// felt safe and secure in his own body.

and if izuku snuck out while both his omega and pup slept?

he scheduled a whole outing day with his little family, just a little arts market kacchan had mentioned a few weeks ago.

it was a great day (and a bonus that they had an alibi, and they didn’t get a whiff of the news: APPREHENDED VILLAINS MISSING, FOUL PLAY SUSPECRED).

— end!

(this is very self-projectionist bc something like this happened to me so what better way than to channel the experience than through dkbk?)
