A/N: Yes, I will be leaving dumb memes in the headers on new chapters unless a new character's being introduced. Considering how many OCs are already in this fic (Kazue, Katashi, Iwata/Tecton, Aerogale, Fueki, Hamasaki, Furuya, Chisaka, and Takibi), there's not going to be that many more.

Took forever to write this chapter, istg.

Also, if you don't know the names of all of Izuku's Quirks, they're going to be listed but not described later in this chapter. Spoiler alert.

~-~-~-~

"Um... Kimura-kun? What are you going to have me do today?"

Midoriya's voice broke Kazue out of his momentary trance. He blinked once, his hand cramping with the speed at which he'd been writing, then slowly raised his head to look at the shorter boy.

Right. He'd almost forgotten.

"Endurance," Kazue replied, all the while berating himself for becoming too focused on one topic to the point where he couldn't multitask. "Start with laps. Maintain one and a half percent for the first five, then lower to one for five more, and half for the last five."

Essentially, it was like a ladder progression for weights in reverse. Rather than start light with many reps, then gradually increase every set while reducing reps, Midoriya would start big and end small with the same number of reps each time.

As an added bonus, it would force the other boy to be able to maintain control of One For All while changing its power percentage.

Midoriya, ever the dutiful student, just nodded determinedly and ran off to begin his laps with green lightning in his wake.

Not even four seconds had passed when the doors to the gym opened and in stepped Kazue's roofmates. Furuya was in the lead, the confident one leading the two girls into unfamiliar territory. He wasn't scared of anything, despite the fact that he possessed roughly as much strength as the average adolescent child.

Kazue could feel Midoriya's surprised gaze flick back and forth between himself and the newcomers while he continued to run at a slightly elevated rate. The brunet, however, simply ignored his first student in favor of striding over to his new students.

"Yo, Shamrock, who's broccoli boy?" Furuya wasted no time in asking rather loudly. Midoriya almost tripped over his own feet at the... nickname? Familiarity with which he spoke? Both?

"Go introduce yourself while you run laps," Kazue replied without hesitation, having essentially created joint physical lessons up until the Sports Festival. Quirk practice would be more of a one-on-one lesson with his roofmates, while Midoriya just needed more experience and direction. "You three do ten."

Assuming he was timing it right, that would mean they'd finish around the same time as Midoriya. Kazue knew little about their physical capabilities, but it was relatively easy to estimate based on the difference in experience.

Mostly. Hamasaki would likely start off strong, due to the innate strength of her legs, but quickly run out of stamina. Chisaka was always out of breath after climbing the many flights of stairs to the roof. As for Furuya... he was a wild card. Full of energy at all times, surprisingly quick on his feet, but lacking in power.

"Ah, shit, you were serious," Furuya hung his head over-dramatically. "I'mma die, aren't I?"

"Probably," Chisaka replied, then dragged him off to the perimeter of the gym where they began to jog. "But I will first."

Hamasaki smiled awkwardly, then jabbed a thumb back at the door. "Uh, you don't think I can just... go, can I?"

"No," Kazue deadpanned, creating three separate graphs in his mind for each person in motion. Position versus time, velocity versus time, and acceleration versus time. He waited a long second before shrugging a shoulder. "If you want to do well in the Sports Festival, that is."

"Noooooo..." she groaned quietly with her eyes squeezed shut. Nevertheless, Hamasaki broke into a fast-paced jog and swiftly caught up to their other two roofmates. Once they were all together, they picked up the pace until their velocity reached Chisaka's maximum.

Kazue simply observed, taking mental notes as fast as his synapses could fire while simultaneously constructing twelve graphs. It was times like these where his mental capabilities were pushed to their limits, but he prevailed. While they trained their bodies, he trained his mind.

Even so, no one but his father and his sidekicks knew his true processing power. Kazue's brain, while it naturally retained anything and everything he'd ever seen, heard, smelled, touched, tasted... it was also mutated due to his mother's Quirk. The ability to process information instantaneously, suited perfectly for the 'read' capability Amplify allowed him to utilize.

He sighed to himself and continued to count down the laps each of his trainees had remaining. Midoriya was doing quite well on his twelfth lap, still going strong at half-percent. Hamasaki had tired after the fourth lap and was half-walking-half-jogging around for her ninth lap. Furuya had yet to break a sweat, energetically jogging backwards while cheering on a stumbling Chisaka. Both were on their eighth lap.

Kazue stared at the latter two for a moment, then raised his voice loud enough for them to hear. "Furuya-san. Finish your last two laps in a sprint."

The other boy shot him a raised eyebrow, shrugged, and took off like a bullet. Kazue... didn't know what to think as he watched Hamasaki get passed like it was nothing, then as he took in Midoriya's face of shock that Furuya was gaining ground on him.

Kazue hid a small smile at the sight. Unpredictable variable, huh? It'd been a while since he'd trained someone with that much energy, and he found himself looking forward to seeing just how far Furuya's stamina would be able to take him.

"Midoriya-san, don't let him pass you," Kazue called out in warning, mildly interested in seeing whether a Quirkless boy would be able to beat All Might's successor in a footrace. "You have my permission to raise to a higher percentage, if you can handle it."

The green-haired hero student almost tripped over his own feet in surprise, but wasted no time in imbuing his muscles with one percent more power.

Furuya didn't stand a chance, fast as he was. He lost ground even swifter than he'd gained it, yet still kept up the quick pace. He finished his ten laps a mere second behind Midoriya completing his fifteen, immediately folding in half and resting his hands on his knees while gasping for breath.

He had the speed, but not the endurance. They could work on that.

Apparently, Kazue's roofmates understood exactly what the calculating look in his eyes meant and they all groaned.

"This is hell," Chisaka muttered, wheezing despite her rather slow pace.

Hamasaki sucked in a breath, nodding several times in quick succession. "I regret everything and all we've done is run."

~-~-~-~

Oh shit-

Kazue lunged forward the second the smoke began to disperse, barely managing to make contact before it could escape. Even if the air conditioning was on low power, it was still enough to blow away Chisaka's form.

He clenched his jaw and pulled, restraining her Quirk and limiting it to only maintaining smoke form. Nothing more. She was, by far, not ready for motion in the slightest.

The girl dropped a few centimeters to the ground a moment later when she deactivated her Quirk, breathing heavily and sweat soaking her wavy bob of brown hair. "Shit, Kimura, how am I gonna do this in time?"

"You don't have to," Kazue replied, keeping his hand on her shoulder. Her Quirk was rather volatile after being used, and she didn't have a great deal of control. He still didn't know why, however, they'd all decided they needed to team up. It wasn't a logical decision, given the differences in abilities of the members, but then again... none of them seemed to operate by logic.

Chisaka made a face of distress, as though she were about to agree and not genuinely try in the Festival after all.

She did not.

"Can't... can't you just control my Quirk like this and get everyone through the obstacle course?" she suggested, stating his plan C. "Like... I can make contact with everyone, and you make us all into smoke without the wind killing us and carry us to the end."

Kazue shrugged a shoulder, observing Hamasaki jump around with Midoriya and Furuya doing weighted squats in his peripheral vision. Today appeared to be leg day. "I could do that, yes, but I'd rather you have more control over your Quirk to lessen the strain on myself."

There were two more events after the obstacle course, of course, and he might end up having to use Amplify for two of them in a row. Then, depending on how the matchups for the one-on-one battles went, he'd likely have to continue to use it. While Kazue was used to using his Quirk for an extended period of time due to his training, this would be pushing that limit considerably.

The one-on-one fights would actually be the easiest, considering that there was nearly a one-hundred percent chance that every competitor would be a heroics student. Everyone's Quirks would be developed and much easier to use against them.

Then again, there was a high chance that Kazue's father would give him a specific challenge. Everything was training, even the high-stakes competition that was broadcasted worldwide and could make or break a new hero's career.

"Training's over for today," Kazue called, his mental clock helpfully informing him that half an hour had passed. "If you want to keep working on your physical capabilities or your Quirks, I'll still be here after school every day after school."

Hamasaki promptly collapsed, Midoriya's training regimen far too rigorous for her to do for too long. She had the leg strength to outmatch Midoriya's current power levels, but her stamina was on the low side. "Help, I've fallen and I can't get up," Hamasaki wheezed, extending a shaking arm towards a panicking freckled boy.

"Call Life Alert today," Furuya completed the advertisement in a voice an octave higher than usual, laying on the floor of the gym and clutching his legs.

Kazue sweatdropped at the sight of every single one of his roofmates so exhausted by a training session only half an hour long. It was understandable, yes, as they had no experience, but he was so used to training hero students that regular civilians were a whole new arena.

"Are... are they okay, Kimura-kun?" Midoriya asked hesitantly, edging closer to the brunet. Unlike the rest of them, he didn't appear to be as winded.

"They're fine," Kazue replied, watching as Chisaka heaved Furuya back to his feet and they both pulled up Hamasaki. He winced at the built-up pressure behind his eyes, rubbing the bridge of his nose in an attempt to alleviate the uncomfortable sensation. "They're just not in the hero course like you."

"Oh, yeah, definitely fine," Furuya managed to wheeze, he and Chisaka stumbling toward the gym doors like their lives depended on it. Hamasaki wasn't far behind, her legs shaking with every step. "Sure, Shamrock, let's go with that."

"See you tomorrow," Kazue replied, unperturbed at the sight. His training was hell, as his current student had since learned. The moment the doors shut, he turned around to face a concerned Midoriya. "Do you want to see what a higher percentage feels like?"

The other teen's eyes grew as wide as saucers at the question. "How...how high?" Midoriya asked, fists clenched at his sides in both apprehension and eagerness to excel.

The brunet's lips quirked up into what could almost be identified as a dry smile. Honestly, the whole offer was more out of curiosity. Midoriya's body wasn't nearly developed enough to properly handle higher than his current one-and-a-half percent. Sure, Kazue knew he'd be able to maintain roughly four percent—give or take a half-percent—but he would struggle to both keep a consistent power level and move with the same ease. "Right now, I can give you enough strength to maintain thirty percent for one minute."

Midoriya's jaw dropped, but his hand was already thrust forward before he could even speak. He nodded hurriedly, a bead of sweat rolling down his forehead. "Yes, please!"

Kazue reached out and grasped Midoriya's hand, then, in a single pulse, transferred the precise amount of energy required. Exhaustion instantly crashed over him like a wave and he stumbled a step back, feeling as though he'd just gone seventy-two hours without sleep. "Have at it," the brunet managed, sitting down heavily on the gym floor.

While he did want to see how Midoriya would be able to handle his current power level being multiplied fifteen times over, that wasn't his true intention. No. With the way that Kazue's training plan was set up, he'd only have the opportunity to use Amplify on Midoriya on the very first session.

His true goal was to further investigate the latent Quirks hiding within. Kazue's 'read' ability was excellent with his eyes, but contact was best when it came to his Quirk and his eyes were already sore as is. He hadn't gotten the chance the first time, as the revelation had come by surprise and there wasn't enough time to fully look into it.

This time, however, he was prepared. The names of the Quirks spun through his mind on repeat, basic information about each attached. Kazue hadn't maintained contact long enough to gain detailed summaries, but it was enough for now.

Gearshift. Fa Jin. Danger Sense. Blackwhip. Smokescreen. Float.

Kazue blinked a few times at the flood of Quirks, his eyelids fluttering as he began to painstakingly sort the new information into his mental file cabinets. From what he could tell, Blackwhip was the closest to emerging, but it would still require a stressful event to 'pop the cork out of the bottle'.

He took a moment to observe Midoriya bounding from one wall to another with considerable speed. So far, he'd fumbled a few times, but was gradually catching on to the necessary timing. It was genuinely intriguing how fast he was able to grow; Kazue wasn't sure if he'd ever met someone with so much potential.

Seven Quirks, entrusted to a fifteen-year-old boy that had been Quirkless. It was unheard of, mainly because nothing like that had ever happened. Even with the other users of One For All, such as All Might, they'd possessed no other power than their own and what had been passed down. Not even the Number One Hero was able to use the Quirks of his predecessors.

Kazue was looking forward to his career.

Chisaka: 0, A/C: 1

Yeah, Furuya's a speed demon, but his endurance is shit. Hamasaki  has the leg strength to jump off a skyscraper and survive, but would literally die if she had to take the  Pacer Test. Chisaka's just plain unathletic (like how I used to be lol, def not self-inserting here).

Next chapter will be wrapping things up (Takibi's first tutoring session, 'conning' Recovery Girl again, and Katashi's challenge for the SF), and then 29 we'll finally be at the Sports Festival arc.

Sure as hell took long enough 💀
