Katsuki

As expected, the ball I'd thrown with a soft, inaudible kiai of 'die', completely blew past my record of 67 meters in my last, quirkless, physical.

I couldn't just scream die out loud! That'd be hella embarrassing!

But, well, I didn't just boost the baseball with an explosion on top of raw muscle power either. I could've but it would've been inefficient.

With all the time I'd spent with Deku, obviously we were going to start talking about our quirks. More mine since he hadn't had one until recently. It wasn't just him training day after day on the beach either. And over the month that he's been taking baby steps with his quirk, I'd joined him in training, trying to figure out ways to improve myself with the gold mine of a training area.

The beach was deserted most days, even after the trash was cleared out the place was well known as a dump.

This meant that since there was no one to disturb and report illegal quirk usage, Deku and I had a chance to really cut loose for the last twenty something days.

I'd known about shaped explosions since I was a kid. I didn't know the science behind it, only that explosions felt different depending on how I shaped my hands or changed the timing of my detonations.

It was Deku that showed me a wiki page when we were kids and helped me study physics and chemistry when I figured out that wasn't just school work, but practical knowledge I could use to better my personal abilities. And now I'd finally gotten to test my studies in a live fire environment as Deku focused on not breaking his limbs every time he powered up.

So taking the long nights of studying I'd done, the practical experience of last month, and my own intimate knowledge of my abilities, I'd thrown the ball.

I'd gripped the ball snugly in both of my hands. Like I was poised to bounce off a volleyball while maximizing the circular surface area where my skin would contact the ball.

Checking my stance, I nodded to myself before lowering the ball and methodically painted a shimmering, pasty layer of slow, and weakly burning gelatinous sweat designed to make the ball spin from a secondary detonation. On the portion that my hands would be touching, I applied much the same, but in layers of denser, firmer, and hardier explosive residue that grew thicker and chalkier the closer said fuel was to the cover of the ball.

Essentially I'd adhoc'd a crude, multi-stage booster mechanism that would be ignited in bursts after the initial primer and thrust that my hands provided. It wasn't perfect, but it'd do the job in a pinch.

So I leaned back, used my body as a catapult, and at the correct angle where my snug grip would've released the ball, both my hands detonated the shimmering layer of glycerin that had coated, but hadn't had enough time to mix with the preparations I'd made to the ball.

A second, third, fourth, and a final fifth delayed explosions caused the ball to fly out of the marked grounds.

Way farther.

Far enough that Toshinori-sensei, who'd unobtrusively and uncharacteristically quietly towered over Aizawa-sensei's side, had to leap into the air himself in order to catch the burnt ball that was still flying at dangerous speeds outside of UA's training grounds.

"Ho…" The bandaged teacher muttered, taking the still smoking ball seconds later from All Might's unaffected hands and turning it over his palm.

"Pretty good. Good to see at least one of my students has invested time in learning how to improve upon their quirk." He nodded at me before tossing the nearly destroyed training object and tilting his head towards the next person.

"Looks like we got a good group this year so I won't bother with motivating you. Midoriya, you're up next."

Deku nods, the slightly nervous look on his face mostly washed away with the shimmering awe in his eyes and the praise he was undoubtedly holding back as he stepped up to the plate.

Hmph. This wasn't much, idiot.

"Ah… is it okay if I take my uniform shirt off, sensei? I think I got one a size too small…" Deku mutters, noticeably straining the blue fabric as he shifted and flexed his upper body. "I might rip it if I'm not careful."

"That's fine." Aizawa nods. "I'll put the paperwork into the clothing department to exchange your clothes."

Izuku nods in return and immediately begins to pull his uniform over his shoulders-

'Man. Deku's sure been filling out lately.' I note carefully as I watch part of his black undershirt be pulled up along the outer covering to show a delicious flash of rippling back muscles before it's pulled back down by gravity.

A year ago while before the whole training montage, I'd been taller than him by an inch or so. In that time, my buddy has gone through one hell of a growth spurt much to his consternation and my own confusion.

Consternation for him because the baggy closed he used to sport were now way too small for him.

Confusion for me because… oh fuck it, yum.

I'm not gonna lie to myself. I'd always thought well of him, and there was no one else who was so earnestly fun to tease. When we'd played house together as kids, I thought he was the best hubby out of all those other snot nosed brats who were too busy raving about their own newly developed quirks.

That hadn't changed as we grew up. Sure Deku was… Deku, but that just meant his weedy, dorky flaws were offset by his charming earnestness, willingness to please, disarming kindness, and his somewhat overbearing attitude whenever I did something to worry him.

That he had the balls to stand up to me when I was doing something dumb like getting sick and trying to drag myself to school last year was only the tip of the things the worrywart had placed on his then small shoulders.

In my fever induced delirium, I even thought it wouldn't be so bad to be doted on him 24/7 if I settled for Deku later in life.

'Which I probably would've anyway.' I admitted, my eyes drinking in the tanned, and delectably toned skin of Deku's arms as he reared back on a single foot in a pitcher's pose.

Izuku was never what I believed to be my type, but he was my best friend and I could do way worse than snapping that tiny ass up and putting a ring on his finger ten years down the line.

That was the plan. It was always the plan if neither of us had found someone else by then.

But now?

Fucking. Yum.

At almost sixteen years old, Deku stood at 5'8 compared to my 5'5, and by the way he still looked slightly gangly despite his body filling out saliva inducingly well, he was only going to get taller. And broader. And thicker. And-

You get the picture.

Fuuuuuuck. When what's left of that baby fat on his face turns into a chiseled jawline with 5 o'clock stubble, maybe a scar or two, he's gonna go from plain faced dude with a god bod to moistened panty dropping tier in the span of an all too sudden day.

There were still a few kinks that needed to be ironed out, but hey, what's a little bit of spit and polish to clean up something that's already hitting most of my fuck me buttons?

Shit, I'm not blind and I can't lie to myself that hard. The small thing that used to be a tiny coal of 'he's kinda cute in a dorky, house hubby way' has turned into a full on wildfire of 'can we please make babies now so I can stop waking up thirty minutes earlier to make sure I don't jump your bones while we're training? That'd be really hot at first but seriously awkward after I get my brain working right again.'

Deku's not dumb either. He's socially awkward, not a complete failure at life. I'm like, 99% sure that he's realized I've been pushing the boundaries in our relationship, a playful touch there, a hungrily lascivious glomp there, and then there was this morning-

"Hah." I huff, folding my arms underneath my breasts and regrettably close my eyes as Deku winds up.

I'd rather not get grit in my eyes from the coming shockwave-

'Yeah, like that.' I roll my now open eyes at the invisible girl who is blindingly rubbing at a persistent grain of dirt that floats at what I think is her eye level. Or at least, that's what I think is happening with how her sleeve are moving and how she's yelping.

"Hold still, keep your eye open." I grunt, reaching out to grab invisible arms and slowly trailing my hands down to grasp the mob's wrists.

"I'll blow out the dirt, just guide me." I order, placing surprised hands along my head so that I could be guided to where the shorter girl's eye was.

"Uhm. O-okay… be careful please?" The formerly exuberant girl quiets down, and as I get closer I can feel the heat of her face warming my lips by our sheer, unseeable proximity.

"Is your eye open?" I ask, quietly, not wanting to speak too loud and hurt her ears.

"Y-yesh!" She gulps, naturally afraid of something so close to her eye.

"Alright, try not to flinch." I say, count down softly, and delicately blow against the speck of dust that remains persistently floating in the air.

"Hey, I felt you flinch." I growl, narrowing my eyes and looking to where I know at least one of hers are.

"S-sorry!" She yelps, and takes a deep breath before lightly tugging on my cheeks to signify that she's ready.

"Alright. Stay still this time!"

It takes a few tries, but eventually the piece of dirt is sent flying away as Deku begins stepping towards us in concern.

"Kacchan? What's up?" He calls out, stopping close enough to where I, and probably the invisible girl can feel the wafting heat of his '5% Power' mode cooling down the furnace that is his powerful body when under the effects of his quirk.

"Eh, nothing. This girl…?"

"T-toru... I mean, Hagakure Toru! K-Katsuki-sama really helped me out of a bind! I got some dirt in my eye from staring too- I mean, because I was too busy watching the ball fly!"

"Katsuki...sama?" Deku raises a brow and makes a confused face that mirrors my own.

I didn't really do much?

Ah well, maybe that's just how this girl talks?

"Whatever. The next mob is going. We should probably watch the competition…?" I say, letting the girl's hands go and she allows them to fall to her sides after a moment of indecision.

It's about then I notice it's that brown haired villager's turn and confidently cross my arms, knowing that there was no way she was going to beat my score-

Ten minutes later I have to remember my anger management exercises as Aizawa-sensei brings up his phone and shows us that it isn't able to track the ball anymore.

Naturally, Deku goes over to congratulate the blushing girl along with the rest of the class.

I really don't like how she's eyeing My Deku up and down like that.

"Sooo… uh… Katsuki-chan?" Toru asks, nudging me with her shoulder and causing me to startle slightly.

"What?" I respond, a little irritated that I'd been taken off guard.

Yeah. That.

"So Izuku-kun is really… um."

"What?" I say again, feeling my eyes narrow into a glare at her irritatingly nervous voice and overly exaggerated flapping of her clothes as she swishes the air between us.

"Ah, I don't mean to pry but…"

"Just spit it out girl, shit." I respond, whispering that last part under my breath.

"You guys are dating right?" She asks, with nervous tingle in her voice and a shifted collar letting me know she's tilting her head.

…

"You know what. Yeah. Something like that, anyway." I grumble, arms still folded as the mob who's been shyly rubbing the back of her head, tenses, and looks my way with a panicked look of apology.

"Um… so do you mind if I…?"

"What? Check him out?" I ask the obvious.

"Ah! No, no, actually that's a little relevant, but-"

"Go for it. It's not like half the class hasn't been staring at him and Todoroki like they're made of eye candy."

Still sizzling beef welly with a healthy side of veggies for Deku and melted fudged top strawberry sorbet for the pretty boy, respectively.

Yeah, Todoroki's hot too. That red haired guy is kinda cute, glasseses dude in an uptight way, and that muscled dude with the moon pies in his pocket if you're into huskier, homey men.

The others don't look bad either. Shit, our class is like an all you can eat buffet where every type of food group is represented.

"Fufu! The boys in are class are kinda scrump, aren't they?" Toru whispers conspiratorially, bumping her hip against mine. "But the girls are cute too~"

My lips twitch downward as my eyes find themselves drawn once more on the mob with the country girl accent.

"Yeah." I grumble succinctly, tapping my finger against my arm.

"Ufu! Well, it's my turn next! Cheer for me Katsuki-chan!" Toru giggles mischievously, her uniform spinning in circles as she happily moves up to the plate.

I'd take the warning for what it was and tentatively slot Toru in the 'allied quest giver NPC section' of my internal faction page.

The girls of this class were pretty fucking hot.

If I wasn't careful, I was going to lose Deku before we'd even became a thing.

Fuck. No.

"Maximum Power Kamehameha!" I hear a voice in the corner of my ear followed by a pathetically underpowered ball landing a few feet away from Toru's voice.

"Yeah, you go girl." I mutter under my breath, doing the bare minimum to maintain a positive relation with my new 'maybe friend', and slide my slim frame next to Deku's steel chorded arm.

"Kacchan?" He asks questioningly, looking down at me with a small, satisfied smile.

Well, he wasn't nervous anymore.

"Mine." I mumble only sorta, kiiiiinda petulantly with what I know is a devastatingly cute pout as I latch onto his suddenly tense arm.

"K-Kacchan? What is it?" His nerves amp back up from buried just under his hot skin to erupting like the probably completely planned uniform malfunction of Mt Lady's literally giant knockers just the other week during a press event.

And now he was nervous again!

Heee~

"Just felt like officially claiming you." I whisper, tugging his powerful frame down so that I can brush my lips against his flushed ear.

Deku being Deku, of course, reacts how I expect him to.

Loudly like a confused pigeon thats faceplanted against a window one too many times.

"C-claimed!? Official!? Nani the what!?" He stutters, doing the little verbal tick of speaking in English that he'd picked up over the training with Toshinori-sensei.

Expectedly, my action and Deku's little outburst is enough to rip the eyes I'd wanted to our way.

Just one more thing.

Letting one of my hands playing with his fingers go, I tug down the collar of his black tank top, pull him a little closer, and peck him softly on the cheek.

"Yup. Claiming." I giggle in that way I know drives him closer rather than farther to figure out what he did wrong, and break my hold on him before we drew too much attention. Toshinori-sensei's teeth were already blinding the sun and making me somewhat ill with his hammy, and badly hidden thumbs up.

...

It wasn't like that actually counted as me asking him out, but it was hopefully enough of a message for Deku to get his fine ass in gear and break the question himself.

I only put on that ten year stipulation before I dragged him yelping into a tux because I could afford to play the long game. And that was how long I was willing to wait for him to pop the question before I'd got fed up enough that I'd toss away a silly, girlish wish of mine.

'I want you to ask me out like a man, damn it!'
