...

If the opening moment had intended to shock Shirou, no such surprise came across his features. Instead of a look of horror, there was simply a single eyebrow raised in curiosity.

His opponent, the third year student who had earlier introduced himself as Mirio, seemed to only smile in response. Whether the boy had been expecting a larger or more dramatic response from Shirou it seemingly no longer mattered.

It was an opening move Mirio had used against all first time sparring partners, getting a psychological advantage before a punch had even been thrown. Whether or not Shirou had encountered somebody with a similar quirk to his own, Mirio didn't know. What he did know was that he could practically feel his blood boiling.

The tension in Shirou's feet was the opening sign that something was about to happen before the weapon creator charged forward, crossing the distance between the two competitors in a flash. In his hand, Torashinai roared through the air with the will to deal damage to the person before it.

The strike struck true but there was the surprising lack of weapon on flesh which usually came when a blow connected. Many on the sidelines could only watch in curiosity but in the middle, Shirou had already garnered something of an understanding of Mirio's quirk.

Mirio, feeling like he had already given too much away, pressed on the offence, his fist cocked back with his target in sight. Shirou reacted in time, gliding slightly to the left to avoid the blow which had threatened to imbed itself into his stomach. He watched as his retaliation strike went over Torashinai's prey but not by his own merit, but rather Mirio having sunk into the ground.

It took only a handful of moments for Mirio to have completely submerged himself from view before Shirou swung out behind him, adjusting slightly to the fact that Mirio was several feet off the ground.

Like his previous assault, Torashinai phased through Mirio but Shirou halted his attack midway, keeping the weapon fixated in Mirio's body. The third year student landed on the ground and Shirou got the answer in that moment he required. It was only when Mirio went to attack him, did he allow Torashinai to glide out of Mirio's body.

Mirio's oncoming attack was a twofold one from what Shirou could tell. The hand reaching for his face was merely a distraction to the fist cocked and primed to strike him in the chest once more. Ignoring the fingers mere inches away from his eyes, Shirou conjured his counter for what was about to happen.

Mirio meanwhile felt himself freeze for the briefest of seconds as his phased fingers didn't necessarily go through closed eyelids, but rather the very wide opened eyes of Shirou who seemed to have realized that he had no intention of permanently blinding a fellow student. Mirio pressed on however and launched his fist forward, this time managing to connect with Shirou's torso.

Only to pull back his hand in shock and pain, blood openly oozing from several nasty cuts he had received. It had been a while since he had felt such pain though he didn't try to let the emotion show on his face. Those on the sidelines could only watch on in confusion, partially because of what had happened and the pace of everything. The entire bout had so far lasted no longer than six seconds and so much had already happened in such a short period of time.

"You crafted weapons underneath your clothes," stated Mirio, having worked out what Shirou had done.

"You aren't always intangible, you have to focus on what part of your body you want to be at any given time," retorted Shirou, mildly reeling from the blow which had pushed the steel he had crafted into his abdomens. The boy could pack a punch that was for sure.

While the words couldn't be heard by those standing in attendance, it was clear that there was some sort of understanding between the two combatants, the following clash was clear as day. Again, it was an incredible display of agility, skill and cunning as Shirou did his best to try and strike down an enemy he couldn't hit while his opponent tried to get an upper hand on a swordsman who was prepared for blows coming from his blind spots.

Breaking apart momentarily, Shirou altered his course of action as Torashinai vanished from sight. Mirio figuring something was afoot, allowed himself to slip beneath the surface once more, forcing his body to reappear several feet behind where Shirou was standing, having expected a trap of some sort. What he hadn't expected to see was that his opponent was not in his line of sight. As his feet hit the ground, Mirio turned around to protect his back and gain some leverage of sight of where Shirou would attack him from. Yet again however, he saw nothing.

Once more, the unfamiliar sensation of pain pierced through his body as an arrow struck his foot, grateful that the tip hadn't pierced his flesh. It would seem as if his opponent had opted not to use a tipped area, choosing to use one with a rubber end. Considering the accuracy of which it was shot, Mirio knew that it had been Shirou's target, his opponent already having utilized the times they had collided to work out several vantage points. Most people out of force of habit, aimed for the torso and head, two of the major targets.

While he could manipulate his quirk to allow blows to phase through when he knew they were coming, having his quirk permanently activated on his torso would prevent him from seeing or hearing anything. Perfect timing was required for him to utilize his quirk to the fullest.

His feet however, as soon as he allowed his quirk to flow through that part of his body he would lose his footing and begin to fall. Shirou had worked out that anytime they were standing across from each other was a time Mirio could be struck.

Shifting his gaze, Mirio looked above him to where Shirou hung more than thirty feet in the air, a black bow in his hands and another arrow notched and ready. Upon the loosening of the projectile, Mirio sunk into the ground beneath him, already having worked out the necessary amount of time to fall in order to find himself next to where Shirou was.

It was with little surprise that once light was once again accepted into his eyes to find Shirou facing him, the two of them on the descent towards the ground. In that brief moment when Mirio had been absent from sight, Shirou had changed weapons once again. The behemoth of a weapon was something which sent shivers through Mirio's system.

The club was nearly the same size as him and seemed to be some sort of hybrid between an axe and a club. Crafted of seemingly solid stone, Mirio prepared himself, watching the swing arc to see where Shirou would try to strike him with the weapon.

Yet it wasn't coming at him.

Shirou plummeted downwards, doing a complete front flip and bringing the club down with all the force he could muster. The moment that the weapon struck the ground the results were instantaneous. For those on the sidelines, they could do little more than scream in panic and shield their eyes as debris was sent in every feasible direction, crashing into the walls of the gymnasium.

Mirio landed on the ground as the dust was subsiding to discover the sheer destruction that Shirou had just displayed. The ground was in tatters, chunks of the ground stuck up from the floor while severe cracks more that half a foot wide spiderwebbed their way to the walls. Yet that was only the surface damage, Mirio could only imagine what had happened beneath ground level.

"You got me," he said sheepishly as he rubbed the back of his head.

"I'm going to go out on a limb here," said Shirou as he hefted the colossal weapon so that it sat on his shoulder. "When you go beneath the surface, distance, timing and angle have something to do with where you next find yourself. You've only ever had to worry about beneath surface areas which were flat. If you were to fall now and try and reappear when your body would theoretically be where a crack of open space was, your trajectory would drastically change."

"You're not far off, when I deactivate my quirk and relocate myself, as far as I know it is only due to two objects of mass not being able to exist in a single location," explained Mirio. "With what you have done to the battleground, I sincerely doubt that I would be able to accurately predict where I would appear."

"Would you like to continue?" asked Shirou.

"No, I think you have given me enough to think about, though if you ever wish to spar again I will be more than happy to be your opponent," said Mirio giving Shirou a genuine smile.

"Very well, until we meet again," said Shirou as the massive weapon he had been holding vanished into nothing. He watched as Mirio went about putting his clothes back on, much to the relief of those who had been in attendance. Shirou had to admit that the student's ability was powerful when used correctly, though the mindframe he'd have to constantly be in would have taken an incredible amount of time to get to the level he was at.

"What's your name?" asked Shirou as Mirio finished dressing himself. For a couple of seconds, Mirio didn't respond considering he had given his name before the two of them had begun to combat one another. Slow realization came through before he gave his answer.

"Lemillion!" he boldly declared.

"Lemillion," repeated Shirou.

"Yes, the hero who will save a million people," said Mirio as he clenched his fist in front of his body, emphasising his declaration.

"Best of luck," said Shirou, Mirio giving him a farewell gesture before making his way across the desolation towards the exit.

While Tamaki followed behind Mirio, Nejire watched on for a little bit longer. Ryuko, the professional hero whom she trained under, had asked her to get any sort of intel that she could about the individual who had battled against her peer. What she had witnessed was something that she had kept rapt attention to and her usual bubbly demeanour had found itself silenced at the feat she had seen. Such things like the ability to leap as high into the air as Shirou had without a quirk that boosted him in such a way were definitely things that Ryuko would wish to be informed about. With those thoughts in her mind, she left the gymnasium following behind her fellow third year students.

With them now gone, Shirou turned his attention to his classmates, many of them staring at him standing in the middle of the destroyed landscape. "So, who's next?" he asked casually.

Understandably, nobody was keen to go first.

...

Principal Nezu sat in his chair, watching the footage from the gymnasium with his paws pressed together beneath his chin. To say that what he was watching was outstanding was putting it lightly. Also in the room were a vast number of the school faculty who had gone to the aid of the first year students when they had been under attack only to arrive at the scene too late.

"Kid's got some power," commented Snipe, analyzing the damage done to the establishment. Cementoss nodded in agreement, already preparing himself to fix the damage that had been done.

"I think that's putting it lightly," said Ectoplasm as she scratched at her cheek. "The force necessary to deal that level of damage is something which shouldn't be possible for someone with his quirk."

"Which means that he did that with just raw strength," stated Snipe.

"Raw strength, the ability to react to the difficult situations placed before him and adapt accordingly, incredible bursts of speed and we haven't even gotten to his quirk," listed Nezu as the camera showed Kirishima stepping forward to challenge. "At this stage if he felt like leaving on his own accord I don't believe that we'd have the ability to stop him."

"But All Might..."

"Isn't here all the time," said Nezu as he turned from the monitor. "The question is how do we keep him here? He was forced here through no will of his own and while he will be wanted by the authorities, he could fend them off if he so wished and only perhaps the top thirty heroes could stop him."

"Should we increase our security?" asked Snipe.

"No, that would make it too obvious that we are watching them," said Nezu. "I dare not set up cameras watching their lodgings under fear that they would be discovered and it could trigger them. Having Hound Dog doing perimetre checks should be enough for the moment."

"Well considering there is no school records for him, should we offer him some Quirk Counseling?" suggested Cementoss.

"I don't think that would be a wise option," stated Nezu, dreading the idea of one of his staff trying to talk to Shirou about when and where to use his quirk. "No, for now I think it best we wait and watch, act accordingly when the time is right. Plus we cannot focus on a single student when we have the Sports Festival approaching."

"And what's to prevent him from wiping out the competition?" said Snipe, pointing to the monitor where Shriou had successfully dispatched Kirishima with ease before beckoning the next student to step forward. The faculty members watched Midoriya approach, the green haired boy nervously moving forward before standing in front of Shirou. There was a brief exchanging of words, Shirou saying something that seemed to trigger Midoriya into action.

It was almost comical, how Shirou dodged the first three punches with ease and on the fourth blow simply extended his foot causing Midoriya to trip over it. There had been a good chance that the boy could have maintained his balance until Shirou gave him a moderate nudge with the end of the non lethal weapon he was holding. Midoriya fell to the floor and as he turned, the tip of the training Shinai found itself pressed to his chest, right where his heart was.

Shirou, his point having been made, turned his attention to where the rest of his peers were located, signalling for the next one to step up to him. As Momo came forward, the members of the staff could understand that this wasn't a training exercise for Shirou per say but he was pointing out the most obvious flaws with his opponents plans of attack.

"Something tells me that he won't go all out in the festival," commented Nezu, hoping that he was right in his beliefs.

...

Shirou took the empty dishes to the sink, he and Rin having finished their dinner for the evening. The sun had long since set and their homework was done for the day (as ridiculous as it was to do homework, though it helped them learn more about the world around them) but Shirou could see a look in Rin's eye informing him that there was something she wished to discuss. Placing the empty dishes down and opting to clean them later, Shirou returned to the table where Rin was resting, one hand holding her head up as her elbow rested on the wooden top.

"Are you aware there is a sports festival coming up?" she asked.

"First I've heard of it," said Shirou as he knelt down. "I take it, it's not your standard school sports carnival."

"Over the top is putting it lightly," said Rin. "We were shown last year's event in class today and it is essentially a platform for everyone to show off their abilities. The flashier your moveset, the higher the opportunity that you will get scouted by a pro. It's basically a giant promotional event staged as a festival."

"Okay, and what do you want me to do?" asked Shirou.

"It's not so much what I want you to do, but what you're going to have to do," said Rin as she sat up straight. "They have a tradition where the highest ranking student has to do an opening speech."

"Yeah, what's the problem with that?"

"The problem is that I know you Shirou," stated Rin, her eyes sharpening. "I know that given the chance, you will say something that will irk the entirety of the world to the point where you are the most hated person on the planet."

Shirou remained silent but didn't dismiss the thought that that was a distinct possibility. "So, with your help to ensure it at least sounds like you, we're going to spend the night working you what you're going to say to ensure we don't get lynched down the street."

"We? So you're participating in the event as well," said Shirou picking up the single word used.

"Of course," said Rin as she flicked a lock of hair behind her ear. "I have my own agenda at the moment."

Shirou wasn't even surprised.

...

The following two weeks passed quicker than anybody in class 1-A could have realized. Between classes and the extracurricular training they did with Shirou almost daily after school had finished time seemed to just fly by. To say that the majority had improved would be an outright lie on the surface. None of them could say that they had witnessed improvement in their battles against Shirou but it had all been a good learning experience about the difference between where they were now and what their ultimate goal was.

One thing that the training that they had gone through was surprisingly helpful was that they were no longer afraid of failure. The almost repetitive nature of getting knocked know and then to force themselves to get up and do it again and again was something they hadn't particularly counted on. It was an awkward conundrum for the faculty to find themselves in when during practical sessions the students who took the loss seemed to learn more from how they had failed then from those who succeeded. On a handful of occasions, members of the teaching staff had overheard conversations of how students had felt that they were so close to a breakthrough, if they were a touch faster, a smidgen smarter or even a little more mentally prepared they could last longer. They weren't focused on actually being able to overcome the obstacle in front of them, just to be able to stand in its presence for just a touch longer.

Understandably, this mindset had ruffled a few feathers and one of the teachers had actually marched in and demanded that Shirou stop what it was he was doing. Present Mic had laid down the challenge and Shirou had instructed the class to wait outside while the two of them, 'talked it out like adults.' From outside the building, they had heard the destructive wails that Present Mic could produce for all of twelve seconds before he went silent and a minute afterwards, walked out of the gymnasium, clutching his right arm whilst walking with a noticeable limp and rightfully looking ashamed as he made his way to see Recovery Girl.

Surprisingly, after the encounter with Present Mic, Shirou did alter his training a bit. When a student got knocked down, they had to do twenty push ups before joining the line again. A little change but a change nonetheless.

A small alarm went off in the room where the room that the students of 1-A were gathered in, signalling that it was time. For a few it was at that moment when their nerves started to kick in. However, the first person to move was where all eyes caught on. Shirou stepped out of the room and was swiftly followed by the rest of the class. The walk behind him was more than a little symbolic as they watched him march on without hesitation. They forced themselves to remember that this was their chance, their opportunity to show just what they were capable of in front of an audience. The world knew what Shirou was capable of, now it was their time to show just what they could do.

...

Hope you enjoyed.
