A/N: Just a quick update 😘 I had like half a brain cell writing this, but you're all so beautiful and fucking amazing that I'm going to post it anyway. Enjoy my garbage writing, okay thanks. 

"Daddy."

"Daddy."

"Daddy."

"Daddy."

"Bloody hell---what, Katsuki?"

Shouto hasn't the slightest clue of what time it is when Katsuki shakes him awake, limbs heavy with sleep and brain full of a sensation akin to white noise as he attempts to center himself amidst the spinning room. He groans, hand coming down to wipe over his face as his eyes flutter open to see the blonde straddled and looming over him with big, anxious eyes.

"Daddy, I heard a noise!"

His harsh whispering is almost like nails on a chalkboard to Shouto's dazed and confused

Shouto sighs. "It's the literal ass crack of dawn, Katsuki, that could literally be any one of the several people who also live in this building. Go to bed."

Katsuki wiggles and bounces until Shouto opens his eyes again, brows knit together in frustration.

"But daddy, I really did hear something!"

"Katsuki---"

"No, listen!"

The overexcited blonde is quiet for all of ten seconds but nothing happens. Not even a cricket outside their window.

Shouto groans.

"Maybe it was just a dream, pumpkin."

"Daddy---"

"For fuck's sake, Katsuki, what?"

He doesn't mean for it to come out as harsh as it does but it's too late to take it back now. Katsuki flinches and curls away at the tone of his voice. His head hangs low, purposely avoiding Shouto's intense gaze. He's twisted and rolling the hem of his shirt like he does when he's nervous and Shouto instantly regrets having raised his voice and cursed at him. He sits up from the bed, one hand resting at Katsuki's hip and the other moving to coax him into eye contact.

"Hey---look at daddy." He taps his chin and Katsuki peeks up at him through the fringe of long blonde lashes, eyes shiny with a fresh coat of tears that tug at Shouto's heart strings.

"Daddy is so, so sorry for yelling, baby. You didn't do anything wrong, okay? Daddy's just really exhausted is all and he gets cranky when he's sleepy. You understand, don't you, darling?"

A sniffle. Katsuki nods in affirmation. He gets cranky when he doesn't have a nap, too.

"B-But daddy..."

"What is it, princess?"

Katsuki opens his mouth but quickly closes it again, eyes focused on the way his thumbs fidget and mess with his pajama shirt.

"I-I s-scared..."

It's a pitiful little whine that Katsuki let's out, followed by the sound of him sniffling as the tears finally fall and now Shouto feels like an absolute asshole for brushing him off so easily. Of course he'd be afraid, especially with the notion in his head that something sinister is bopping around in their bedroom.

Daddy of the year, Shouto, really. Might as well rename yourself Enji Todoroki and grow a fucking flaming beard.

"Oh no, don't be scared, kitty. There's nothing to be afraid of---"

"B-But the monsters---"

"There aren't any monsters, pumpkin. Daddy promises there aren't any monsters. And if there were any, they'd never be able to hurt you cause Daddy's right here to protect you no matter what. You believe that?"

Katsuki gives another affirmative nod because, yes, he does. He trusts Shouto more than anyone else in this world and he didn't have the slightest bit of doubt in his sweet little heart that Shouto would do whatever it takes to make sure his baby is safe but still---

"C-Can you...check the bed for monsters?"

Shouto goes from exasperated to absolutely enamored in record time, having to mentally beat the urge to smile back with a stick as the corners of his lips curl at how absolutely adorable Katsuki is.

"Yes, honey, I can check the bed for monsters. Stay up here where Daddy can see you, okay?"

"Okay!"

Shouto slides out of bed with a groan, a few of his limbs crackling as they set into their rightful place. He'd done quite the number on himself the prior while training with his father---he was definitely going to feel that tomorrow morning. He rotates his arms and adjusts his sleep shorts before dropping down onto his front to look underneath the bed, carpet scratchy against his bare chest.

Just as he thought, there was nothing there.

He jumps back up with a huff and holds his arms out at either side of him as if to show Katsuki that he'd returned from his hunt empty handed.

"See? No monsters, just like daddy said. Feel better?"

"Yes, papa. Thank you." He said with a relieved smile. Shouto leans over to place a tired kiss on cherry plump lips.

"You're very welcome, kitty. Now, let's go back to bed, okay? Daddy needs his beauty sleep."

Katsuki giggles but curls into Shouto's side after crawling underneath the blankets with him. Maybe now he could finally get some rest.

#

Going to sleep had proven to be a more difficult task than Katsuki was prepared for. Not because he had heard something or because he'd heard something going bump in the night---he was far past that and had the utmost assurance that his big, strong daddy could beat up all the monsters---cause he's the best.

Well, All Might is the best.

But Daddy is a close second.

The culprit of Katsuki's restlessness, however, is a familiar foe.

His bladder.

He's been holding it for quite some time now, not wanting to wake his daddy again but now it's nearing unbearable and painful as he twists and turn in their bed.

Shouto stirs from his sleep after a few minutes of being unintentionally kneed in his side, tossing an arm around the explosive boy's thin waist in an attempt to quell him but it does little to nothing.

"Katsuki. What is it, baby?" His voice is deep and groggy and very much exasperated, but he's trying his absolute best to have patience with him.

"I-I-I gotta potty..."

Shouto groans again. "You can hold it, can't you, baby?"

"I---I can't hold it!"

There's a long pause and after a while, Katsuki can hear Shouto snoring again. He sighs and weighs over his option.

1. He can try to hold it until morning and risk wetting the bed.

2. He can wake Daddy again and risk being fussed at.

3. He can be a big boy and find the potty by himself.

None of those sounded like pleasant options, but the most bearable option seemed to be braving the dark corridors on his own to find the bathroom.

He scoots off of the bed as gently as he can as not to wake Shouto and tip toes over to his desk where his All Might plushy is sitting. He raises it to eye level and squeezes it's tummy.

'Never fear! Do you know why? Because I AM HERE!'

Katsuki smiles at the little voice recording and hugs the plushy into his chest as he turns on his heels and leaves, careful to shut the door as quietly as possible behind him. Once he's out into the dark corridor with nothing but the light of the moon to guide him, he realizes he may have just taken on a task he wasn't ready for.

"I-It's r-really s-s-scary, huh, A-All Might?" He says, squeezing the toy again.

As long as I am around, you have nothing to fear!

"Y-You're right! A-and I-I-I am a b-big boy!" He takes a deep breath and steels himself.

"Let's go potty, All Might-sama!"

#

Katsuki finds the bathroom fairly quickly, which was a pleasant surprise to the little blonde. He supposes maybe he should be grateful for the several signs hung around the building that guide him in the right direction. All Might has kept him company and encouraged him to brave on through even the darkest hallways, which is why it's his favorite toy.

Ellie doesn't encourage him. She just watches him with her judgemental eyes.

A happy gasp leaves Katsuki when he sees the bathroom's entrance just a few feet away.

"Look, All Might! We did it!" He breathes out in a whisper as he happily pads closer to the door. The urge to pee becomes stronger, almost like his body can tell that there's a toilet nearby and it's just bordering on uncomfortable.

"Agh---mmmrph!"

Katsuki practically slides to a halt at the noise, nearly crashing into the entryway frame. It's the noise he heard earlier, like an angry animal or a beast who's just won its prey. The sound of whimpering and whining and sliding---almost like a struggle, that accompanies it along with the sound of something that reminds Katsuki of playing outside in his rain boots after it storms and daddy let's him splash in the puddles.

He's shaking, holding All Might by the head in a crushing hold.

What if the monster got one of his friends?

What if they're being eaten by the monster?!

What if they're trying to get away?!

"W-w-w-we h-h-have t-to h-help!" He whispers to All Might, who says nothing to encourage him this go around.

Katsuki swallows audibly around peeks around the corner.

It's hard to make out in the dark but he can see the silhouette of someone on their knees scrambling---can hear them choking as someone looms over, movements violent and calculated. It almost look like they're shoving something down their throats!

'Oh no! I have to help! I have to save them!'

But he's not sure how he can do that. Should he call for help? Should he try and fight the monster by himself to save them? His anxiety skyrockets and he squeezes All Might as hard as he can to try and quell his shaking but---

'Everything will be just fine! Why? Because I AM HERE!'

Katsuki's breath catches in his throat and the shadow jerks to a halt, movements stuttering violently as an inhuman noise echoes against the bathroom followed by a loud scream.

Katsuki thinks his heart is going beat out of his chest and he screams, too. His bladder empties itself between his thighs and onto the floor, teeth chattering as his tremors become violent. The shadow moves and Katsuki tenses and curls into himself, squeezing his All Might plushy so hard that one of its eyes pop out---

And then the lights come on.

"Katsuki?"

The blonde's eyes snap open and he come face to face with one Eijirou Kirishima.

"E-Eiji-nii! You're alive!"

He nearly pulls the redhead onto the floor with his bear hug, nevermind the uncomfortably wet feeling between his legs as he begins to cry. His All Might plushy lays forgotten on the floor.

Eijirou seems very confused.

"Hey, whoa. Of course I am, baby, why wouldn't I be?"

"T-the monster---the m-m-monster w-was here a-a-and it w-was g-gonna eats you!"

Eijirou pulls away from Katsuki's hug to wipe his face and attempt to calm his hysterical tears.

"Monster? What monster?"

Katsuki points over to the corner where he saw that menacing shadow and pauses when he sees Izuku on the floor---on his knees---wiping spit and drool from his face. He turns beet red when he makes eye contact with Katsuki and quickly tries to wipe away the rest of the thick liquid with paper towels he finds on the counter. It's all over his chest too, bare as it is, covered in scratches and bruises.

"Oh no! T-the monster got Zuzu!"

Eijirou looks over to where Izuku is sitting and snorts, trying to hold back the obvious laughter bubbling up in his chest.

"Oh, honey---"

"The monster did get me, Kacchan! But because you were so brave, you scared him away. Such a brave boy." Izuku butts in, glare cutting right through Eijirou as if he dares him to say another word. He snorts again and raises his hand in surrender as Izuku begins to dote and love on the fluffy blonde ball of sunshine.

"What are you doing down here so late and all by yourself, hm?"

"I-I-I h-had to potty..."

"Had to---oh. Oh, sweetie."

Tears well up in Katsuki's eyes again and his knees rub together, trying to rid himself of the incredibly itchy and uncomfortable feeling of urine drying on his skin.

"I-I'm s-sorry, I didn't m-mean to!"

"Oh no, sweetie, it's okay! You were just scared, it's not your fault. Let's get you cleaned up, okay? Don't worry, you're not in any trouble."

"P-Please don't tell Daddy!"

"Don't tell daddy what?"

Katsuki freezes when he hears Shouto's still very exhausted voice from behind him. He curls into Izuku with an embarrassed whimper.

"He just had a little accident is all, no big deal." Eijirou says, hoping that Shouto would just leave it at that.

But when has Shouto ever let Eijirou have his way?

"Oh, I see. Did you not make it to the potty in time, baby? Why didn't you wake Daddy so he could take you to potty?"

Katsuki huffs. "I did. You fell back asleep again!"

He scratches the back of his head sheepishly.

"Oh."

"Can we not just let him stand here in his own piss, please?" Izuku intervenes as Katsuki fidgets uncomfortably once more.

"Sure, I'll go get him some clean clothes so we can get him another bath. What were you guys doing down here, anyways?"

Katsuko thinks Izuku kind of resembles a deer stuck in headlights.

"We---uh---ahm---"

"They were being attacked by the monster, daddy! But I saved Zuzu and scared the monster off!"

Shouto's brow raises and Izuku feels a concerning amount of heat clawing up his neck. He registers the exact moment that Shouto takes note of the bite marks and bruises peppering his skin.

"Uh huh. What was the monster doing to Zuzu, baby?"

"Shouto---"

"It was really scary, daddy! He was choking him and stabbing him down his throat!"

"His throat? Oh, yeah, that does sound scary, baby. What did the monster look like?"

"Shouto, please---" Izuku pleads, entire body red with embarrassment now but Katsuki is much too invested in regaling his close encounter with this monster.

"I-I-I couldn't see too good in the dark b-but when the l-light came on, it ran!"

"I see." Shouto says, a sly expression on his face as he makes eye contact with Izuku. He decides to have mercy on him. "My brave boy, you did so good. Go to the washroom with Eiji for me and daddy will be there in just a bit to help clean you up, okay?" He sends them off with one last kiss, stepping over the puddle of urine to stand over Izuku with enough scrutiny to make him squirm.

"What?" The freckled boy hisses out at him, arms folded over his chest.

"So are you actually going to let him believe there are monsters in the dorms or are you going to come clean and tell him that what he saw was you getting skull fucked in---"

"BECAUSE HE'S A PRECIOUS BOY AND HE DIDN'T NEED TO SEE THAT, OKAY? Are you happy, Shouto? Did you enjoy embarrassing me?"

"Honest answer?"

"I hate you."

"You love me."

"Not anymore, you traitorous bitch."

"Whatever you say, Zuzu. Have fun cleaning up piss all night."

Izuku huffs at his so called friend. Standing to his feet with a sigh as he looks at the mess on the floor. He supposed since it was his fault that Katsuki ended up emptying his bladder onto the bathroom tile, he'd take the responsibility of mopping it up. He doesn't miss the smug look Shouto throws him on the way out.

"One of these seasons, I'm gonna kick your ass."

Shouto pokes his head in from around the corner. "What was that?"

"Nothing, just go clean the child!"

Shouto's laugh echoes as he leaves again.

"Sometimes I wonder why I even agreed to be apart of this disaster family."

And he smiles, because he knows this is the family he'd always wanted. Maybe it's okay to let them drive him a little crazy every now and again.

Maybe.
