Midoriya stood in awe at the aftermath of the fight that had taken place in front of him. The floor was torn up and rent in different places, either from the heavy charge of the transforming student Tamaki's charges or his various attacks, or blasted apart by the spiralling blasts let loose by the flying girl Hadou.

Kanetsuki threw down the towel he'd been using to wipe down his face and turned to face the three students he'd been sparring with, bringing one hand up to press an ice compress against the bruised cheek that even now my quirk was rapidly healing. One of the sleeves of his shirt had bene ripped away entirely, after the Pro Hero had made use of it to pin one of his opponents in place and of the fight. The boots he was wearing were literally smoking at the moment, and as Midoriya looked at the arena once more he could make out shoeprints that had literally been burnt into the floor, almost like the after effects of Endeavour's Flashfire Dash.

The Big Three were on the floor before me in similar states of disarray, Tamaki having pressed himself up against a wall as an impromptu support to keep himself upright with his face covered by an ice pack, Mirio down on one knee breathing heavily as he slowly forced his body to take in air at a normal rate, and finally Nejire splayed out on the floor like a dog that had exhausted itself running about at the park and promptly collapsed as soon as it got home.

He was still in shock at the fight itself.

He'd thought that after what he'd seen at the USJ he'd understood what it meant to watch people with expertise in their quirks fighting looked like.

But this?

The three students clearly had experience working together, if the way they seamlessly worked together was any indication. If it weren't for Kanetsuki-sensei saying otherwise then he would have believed that they were already pro heroes instead of just students.

They'd even managed to land hits on a Pro Hero a few times, someone in the Top 20!

But at the same time, watching the Pro Hero Shiro Madoushi in action was even more incredible.

The only times Kanestuki had been caught on camera using his Quirk was the photo of him holding back Kurobe Dam that everyone instantly thought of when someone thought of Shiro Madoushi, and a few clips of him helping out disaster zones and after accidents, assisting in the recovery and healing of civilians.

But even with all his practice researching heroes, when Midoriya had tried to search for information about the Number 12 fighting, all the news clips and videos were of the aftermath to the fight, or were so blurry that they were practically unwatchable.

After watching what had taken place, Midoriya understood why.

Kanetsuki coughed lightly, the sound drawing Midoriya out of his own thoughts. "Okay then kids let's get started with the review." Kanetsuki spoke up, one hand going up to brush his hair out of his face.

Review?

"Oh you must be wondering what he means by that don't you Midoriya!?" The female upperclassmen said brightly, turning to face towards him from her position on the floor. "Whenever we have a spar like this, even when he's not involved, Kanetsuki-sensei makes us do an analysis of what took place, both of our own performance and our teammates as well as his own! He says that we should do it while it's still fresh so we don't for…"

"Nejire, let's start with you." Kanetsuki sensei interrupted with a wry grin as his student tiredly pushed herself up to sit cross legged on the floor. "I'm glad you listened to my advice from last time. While your more powerful attacks can certainly change the battlefield, your last attempt had me telling you that most opponents are not going to give you time to charge up your attacks. You, are going to have to force me give you time. And I have to say that increasing your flight time is certainly a way to do it."

Despite her clear fatigue from the combat that had just taken place Midoriya was still shocked at just how energetic the more experienced student was. "Awesome! Did you see how much better I am at flying this time? I learnt how to use my hands to help stabilize my flight, because I kept trying to fly without it, but I kept just flying all over the place and wasting my energy, so I asked Ryukyu and she…"

Kanetsuski-sensei stood there and waited for Nejire to finish talking, with an expression that seemed to be equal parts amused and annoyed.

The blonde student, Mirio laughed and spoke up, interrupting the verbal assault. "I think Kanetsuki-sensei has something to say, Nejire."

Nejire stopped and turned towards Mirio at that, blinking owlishly. "Then why didn't he say anything?"

Midoriya heard the teacher let out a sigh at that before he spoke up again. "Alright, yes I see that you've made great improvements to your flight since last time Nejire." The sound of his voice neither approving or disapproving. If Midoriya had to describe it, he would have called it clinical, like a doctor examining a patient.

"Nejire-chan!" Nejire interrupted her cheeks puffing out at how he addressed her.

Kanetsuki-sensei continued on, ignoring her outburst as if it had never happened.

"Now your use of the flashbang, normally great idea, but if you have allies fighting alongside you who aren't expecting it, it can be more harmful then helpful." He finished with a wave of his arm indicating the dented wall where a blinded Tamaki had crashed head long into it, leaving him stunned for an easy attack by the Pro Hero.

Nejire winced at that, turning towards her fellow student, clapping her hands together and bowing her head in apology. "Sorry Tamaki! I won't do it again."

Izuku couldn't make out the muffled reply through the ice pack that the student with the transformation quirk said, but given the way that Nejire perked up it seemed likely that he had forgiven her.

"And while flight is a wonderful way of ensuring that you keep distance with your opponent, don't forget that just because your opponent can't fly doesn't mean that he can't reach you." Kanestsuki continued on, bopping Nejire on the head with the bokken, now cracked and splintered compared to the immaculate finish it had had possessed at the start. "Repeat after me. Never assume that you're out of reach."

"Never assume you're out of reach." Nejire dutifully responded, one hand coming up to rub at the spot where the bokken had bounced off the top of her head.

"Other than that? Well done over all. I like how your able to control your flight on your own purely via your quirk instead of having to rely on hero tools instead. Given how your Quirk drains your stamina, my advice is simple, do what you can to increase it even further." He said, an approving tone to his voice.

Nejire snapped a hand to her forehead to give a sharp salute at that. "Yes sensei!" She replied happily, smiling broadly in response.

Kanetsuki nodded before turning towards Tamaki who was still propped up against the wall, but Izuku could see that he was clearly playing close attention to the teacher's words.

"Okay first off, that new technique Centaur? I love it. The sheer shock factor of something like that is going to throw most people for a loop the first time they see it." Kanetsuki-sensei said approvingly, applauding briefly as he did so.

Izuku agreed with him. The sight of Tamaki stampeding forwards during the spar, the floor shaking from the force of his passage was enough to cause his heart to race at the mere sight of it. He couldn't imagine what it was like to actually come up against it.

"That being said," The teacher continued, wincing as he presses a particularly tender part of his face, "It's pretty clear that you're not used to moving around in that form yet. Understandable given just how much of a difference it is to your normal movements, but at the moment it's a glaring weakness to the new technique."

Again, another fair criticism. After the flashbang had gone off, blinding not only the students but also Izuku himself when he was able to see properly again, Suneater was still trying to stand up again on all four legs before he eventually decided to abandon the technique, transforming his legs into something more reminiscent of a raptor then a horse.

But by that point Nejire had already been struck from the sky by Kanetsuki.

"When you fell you had no idea how you were supposed to get yourself back up. That's just a matter of getting more practice in with your form I suppose, but great initiative throughout the fight on your part." Kanetsuki finished, praising the teen's performance.

Tamaki only pulled his hood down further at the teacher's words, seemingly trying to hide within it, mumbling a response so quietly that Izuku couldn't make it out.

His two teammates could however if they're laughter was any response.

"Still can't take a compliment though." Kanetsuki said with a sigh, pulling the ice compact away from his face to reveal the bruise on his cheek had vanished, his face just as immaculate as it had been when he had first entered. "And finally, we turn to you boy wonder."

Mirio leapt to his feet in defiance of the exhaustion that clearly gripped him, smiling broadly. "How'd I go teach?"

"Well your battlefield awareness has gotten even sharper so I applaud you for that, but you've still got to remember to be aware of where your allies are when using your quirk." He began, cautioning the senior student.

Izuku winced as he remembered the kick that had scythed through Mirio's head as if it wasn't even there to crash into an unsuspecting Tamaki's chest, blasting him off of his feet, and causing yet another dent to be formed in the wall.

If the sparring match he had just watched has taught Izuku anything, it was that Kanetsuki did not hold back when it came to sparring.

"You might have avoided my blow entirely, but because your form was obscuring my attack Tamaki had no hope of seeing that kick in time, which was exactly why I did it." The teacher admonished lightly before his face seemed to take on a peculiar expression.

"That being said, the way you dove through Tamaki to punch me in the face was inspired, very well done, if not for the fact that you left yourself in the air afterwards."

Mirio's broadening grin seemed to fracture at that as the other two students let out low hissing sounds in sympathy.

"What's the first rule of aerial combat if you can't control your movement freely in the air?" Kanetsuki asked dryly, even as Mirio hung his head with a sigh.

"Don't do it." The three exhausted students droned in a way that said this was not the first time that their teacher had tried to teach them this lesson.

"Why?" He continued, half a grin on the hero's face as he awaited their response.

"Because it's a dumb idea and you'll make us all do laps until it sinks in."

Kanetsuki nodded seriously at that. "That's right. Speaking of which, you'd best get started if you want to be finished before classes resume.

A new chorus of groans rang out at that, but the three upperclassmen pulled themselves up and started jogging around the outside of the training hall, taking care not to trip over any of the new dents and craters that had been left in the aftermath.

"Midoriya!" Kanetsuki-sensei's called out loudly waving him over to where he was standing. "What were your thoughts on the match?"

"Sir?" Midoriya responded questioningly, not knowing quite what he was expected to say here.

The teacher looked at Midoriya's clear expression of confusion and rolled his eyes, the wry grin he always seemed to have spreading across his face. "I won't bite." He said teasingly. "I read your responses to the problem question for the entrance exam. Your level of analytical analysis of Quirk is astounding at someone your age. I know I wasn't half as good as you are know when I was that young." He said, praising Midoriya directly.

Midoriya had to fight back a blush at that. He was still getting used to teacher's treating him with more than thinly veiled mockery like they had back at Aldera Junior High.

It was a nice feeling.

"So in your opinion, what would you think is the most powerful aspect of my Quirk that you saw on display out there?" The teacher prompted, his expression controlled as he stared down at the much shorted student. "My durability? My mobility? He suggested.

Midoriya thought over the fight again, of the way that he'd been able to block blows of incredible strength, of the way he'd been able to pursue and even outpace the speed of his opponents.

It was certainly powerful.

But that wasn't it.

Through the whole fight, Kanetsuki had only thrown a few actual 'attacks' at his opponents, but when he had done so it had been to devastating effect, during brief moments of vulnerability or in a way that turned his enemies strengths into their own downfall.

It was almost like watching Nighteye, All Might's final sidekick in action weaving around attacks as if he had already seen them coming.

Midoriya gave his answer and Kanetsuki blinked at him for a moment before roaring with laughter, a broad grin on his face. "Well in a way I guess your right, but not exactly." He said chuckling before pulling a playing card forth with a flourish with one of his hands. "As far as I understand it, Nighteye's quirk lets him see the actions that another is going to take in the future for a certain length of time, allowing him to make actions that would in turn counter or avoid those actions entirely. He threw the card with a flick of his wrist sending it spinning across the room before it reversed course and slapped back into his hand.

"I on the other hand see the action when it happens." At his words he threw the card again and closed his eyes, only this time instead of the card reversing it's path it continued forward, arcing through the air like a boomerang as it looped around towards the Midoriya. "I just make myself fast enough to react to it before they can finish it." the pro hero continued, eyes still closed, before his hand flashed up on a blur of movement and caught the card just before it would have bounced of Midoriya's forehead.

Midoriya found himself gaping at that.

That was…

How were you supposed to counter that!?

It was like trying to outpace someone in a footrace when they were in a sports car!

"I think you've got the potential to be able to do it yourself, when you've got your Quirk more under control." The teacher said earnestly, the reassuring words having the opposite effect.

The power he'd inherited from All Might, One For All, was ludicrously powerful. The first time he'd used it, he'd shattered every bone in his arm and both of his legs, and that was after spending months training under All Might to make himself strong enough to survive using it.

How was he supposed to learn how to control that?

"Togata! Get over here!" Kanetsuki called out, signalling for the other two to continue their laps, the words distracting Midoriya from his self-deprecating thoughts.

Mirio jogged over, running on the spot when he stopped approaching. "Something I can help you with teach?"

Kanetsuki clapped Izuku on the shoulder. "Bucket the younger, meet Bucket the elder." He said broadly, gesturing first to Izuku and then to Mirio.

Mirio blinked at that before his grin spread. "Does this mean I'm no longer bucket the younger?"

Kanetsuki laughed at that. "You'll always be bucket the younger to me kid." The teacher disagreed with a smirk. "Time to teach the next generation the way of the bucket."

The teacher went to say more before a chime went off and Kanestsuki lifted his phone up out of his pocket and cursed. "Blast it, I should have been back at the classroom by now." The teacher griped, hurriedly pulling his jacket on and smoothing out his outfit as he made his way towards the doors, "I look forward to seeing everyone's performance at the Sports Festival!" He called out over his shoulder hurriedly, and then he was gone, dashing out of the door.

Midoriya stood there, shocked at the teacher's sudden departure only to feel a hand ruffle his hair as Nejire strode by him, her sunny smile lighting up the room as she did so. "He's always running late." She said in a loud whisper, giggling as she did so. "Ryuko says the reason why he'll never be in the top Ten is because he'll never manage to make it to the ceremony on time."

"Probably because of his car breaking again." Tamaki's voice emerged from beneath the hood, his response slightly distorted by whatever it was that he was chewing on.

As Nejire and Tamaki continued chatting away, making their way out of the training room, Mirio turned towards his underclassmen and gave a bright beaming smile.

"Alright Bucket the younger! I am Bucket the elder, your new mentor on the path of the bucket to help you achieve greater control and understanding of your quirk!" The blonde said cheerfully, gesturing dramatically all over the place as he did so.

And as he stood there, watching his upperclassmen pose all over the place, he felt the lightbulb click on as realisation stuck him over the back of the head like a Detroit Smash.

"I'm the bucket!" He almost shouted staring down at his hands as the realization of what he had just learned started to sink in.

Mirio's grin spread even further, clapping both of his hands on the boy's shoulders. "You're the bucket." He agreed, nodding as he did so.

As Mirio started talking again about his own experience as 'the bucket' and how he'd learnt how to use his quirk, one thought dominated all others.

This…

This changed everything.
