Shirou finished cleaning the dishes and wiping down the bench, ensuring that his workspace would be clear for the coming day. Dinner tonight had felt...off for lack of a better word. He had been feeling off all day to be honest and he knew that his reactions had been a touch harsh. Knowing now what had become of his confidant in Rin, he had been able to calm himself down.

The whole concept though of cooking dinner without her by his side was still something that would take weeks if not months or even years to get used to. Hearing her voice bickering about one topic or another to which he could banter with had been something of a staple in his life. Knowing that silence would be his companion for a while, it was an interesting concept for him to get used to.

There was always the television he supposed.

Checking the time, Shirou rolled his shoulders before making his way towards the exit. He had a deadline to keep after all. Heading out the door the first thing he could feel was the chill of the night air dancing across his skin. The second thing he could feel were the sets of eyes locked on his position.

Was he at all surprised by this development, not at all. If anything he would have been more shocked had there not been people watching his every move. His partner had left the premises after all without consulting anyone and as such there was a theoretical possibility that he would flee as well. Of course he had no intentions of doing so but they were wary of any possibilities.

"Are you guys going to keep watching from a distance or going to be social?" asked Shirou, looking over his shoulder at a nearby tree. There was momentary rustling before two figures leapt down.

"Your knack for knowing when you're being watched is frustrating," said Eraserhead, complete in uniform. Again, Shirou couldn't blame him for being prepped and ready for any situation. Also he could understand why Aizawa had been assigned to this position. They still thought that his ability to produce weapons was the result of a quirk as opposed to his magecraft. It made sense to send in the teacher who was capable of preventing people from using their abilities, even if his quirk was useless against him.

"Then you shouldn't be so obvious," retorted Shirou with a light smile.

Aizawa couldn't help but click his tongue in annoyance, knowing full well that it wasn't that he was terrible at not being discovered but rather Shirou's situational awareness was ridiculous. Thankfully, Ectoplasm didn't rise to the taunts either and simply gazed at Shirou with a look of humour. "Truly, our future looks grand with you as part of it," he commented.

"Perhaps," said Shirou with a shrug of his shoulders.

"I bore witness to how you instructed your peers today," stated Ectoplasm. "Your methods may be unconventional but it is clear that they are benefitting from your teachings. Pray tell, were you taught in similar methods?"

Shirou allowed a thoughtful hum to resonate from his throat as he put his hands behind his head. Beginning his journey towards where he would be making his demonstration, Shirou answered. "To say my mentor was harsh would be an understatement. The first time I held a weapon against her she knocked her down within moments. Days would pass by and no matter how many times I stood up she would knock me down just as fast. Increasing my time combatting her by a single strike was a sign of improvement, by two was a miracle. It was brutal, yet effective."

"I trust such measures were done only due to necessity," declared Ectoplasm.

"The opposite actually," said Shirou with a chuckle. "She didn't want me fighting in the slightest despite what was happening."

"And she taught you why exactly?" asked Eraserhead.

"Because I wouldn't take no for an answer," said Shirou flashing a cheeky smile.

Aizawa could only respond with an elongated sigh.

"By the way, we should warn you," said Ectoplasm as they closed upon the gymnasium. "Word may have spread about your coming demonstration."

"I blame Midnight," Shirou swiftly accused.

Neither Eraserhead or Ectoplasm could deny the accusation.

"How many should I be expecting?" asked Shirou as the three of them closed in on their destination.

"While the number is quite vast," stated Ectoplasm, "I believe you should be more worried about the calibre of those in attendance."

"So some top tiers are here then," acknowledged Shirou as they stopped at the gym where he had a rough idea of what was awaiting him.

"I would implore you not to do anything reckless," said Aizawa as he gripped the handle. "However I know that you wouldn't pay attention."

"I'll keep that in mind," said Shirou as he opened the door and embraced what was before him. First thing that his eyes noticed was that the gym had undergone some serious renovations in the last few hours. Most likely for the protection of the school property, now hardened cement covered the floor whilst several pillars now stood tall creating some obstacles which he assumed were for viewing entertainment.

The mumbling that had been going on before his arrival was swiftly silenced with all eyes drawing to where he was standing. A quick head count had Shirou estimating that the number of people present was close to the triple digit mark if not a little over. The only member of the faculty that he was aware of not currently present was All Might. He did kind of drop this out of the blue so it wasn't surprising if somebody couldn't take time out of their schedule.

Many of those who had come were not people that he was aware of and he assumed that many of them were here to try and gain his favour in hopes that he would intern with them. There was a high chance that none of them were aware that he was forbidden from interning with any of them but if they didn't know that fact then when he failed to arrive at their base they would simply assume he went elsewhere. No point in bursting their bubble.

A few were heroes that he was aware of. Ryuko had come once again and she had a gleam of determination in her eye. It seemed as if their brief tussle from the other day had made her eager to witness what else he was capable of. Also here was Ryuko's friend Uwabami that he recognized from that night in the penthouse.

There was also one face that he was very familiar with. After all it had been someone whom he had launched a weapon at during the tournament, someone whom he hadn't actually been fighting against. Someone whom would likely agree if he was to ask for some assistance in showing off what he was capable.

Endeavour, the number two hero in the country behind All Might. He hadn't really paid much attention during the fight itself. Todoroki had an uncanny ability that could reshape a battlefield in the blink of an eye, hence there was little time to turn away. Had he had that little bit of extra time to realize just who it was that he had been adamant of launching a lethal weapon at, he might have rethought his actions. However, the man had disrupted his lesson so the punishment seemed just.

Shirou watched as every set of eyes in attendance followed his movements as he walked forward and stood before them. A vast number of those dubbed as heroes by society, and here he was standing before them. Yep, this wasn't quite what he had expected but he'd make do.

"Thank you everyone for being here," he started, clapping his hands lightly together. "I don't know how many of you found out about this but the fact of the matter is that you are all here I'm going to assume for the same reason. Tonight, I have been asked to demonstrate some of the possibilities of my power. You will be happy to know that during these times I will likely need a volunteer and if nobody wishes to join me I will have to choose blindly when asking for assistance."

Quite a few select individuals knew straight away that as soon as Shirou had set eyes on those in front of him that he already had selected whom would be joining him in front of the rest.

"A hero first and foremost, should be able to protect any and all that they are able, regardless of the impossible odds before them," said Shirou as he placed his hands behind his back. "It should not matter how difficult the challenge before them is, a hero will always be willing to put themselves at risk to protect those unable to protect themselves. As many of you are aware, my ability allows me to craft any weapon that I have seen and any abilities that go with it."

"Weapons don't possess quirks," said one random hero, skeptical of what Shirou was getting at. "How is one sword different from another?"

"Weapons don't possess quirks," repeated Shirou as he stroked his chin. "Tell me then, how was it that a single sword trapped in stone selected a single soul that was capable of removing it from it's entrapment? Would you consider that sword the same as one wielded by samurai of years long since past?"

"What you're talking about is a legend..."

"There, right there," said Shirou. "The sword in the stone is legend, one which has passed through the centuries yet even in this present day and age it is still well known. It is not the only legendary weapon by far. For centuries there have been tales of weapons that can split mountains, part oceans and even split the sky. Their strength is sometimes more well known than those who wielded them."

"Are you saying you possess such weapons?"

Shirou manifested two swords into existence, the twin blades looking only minutely different from one another. With a simple gesture of the hand he beckoned one of the heroes who had come to see him to step forward. At first they looked momentarily uncertain but knew that considering the amount of their peers beside them they couldn't really back down without being scrutinized. As they stepped forward, Shirou spoke. "Firstly, I want you to take this blade here and strike at the pillar behind me, then do exactly the same with the seconds. That is all."

Again they looked at Shirou questionably but knew that they weren't really in a position to not do as they were asked. While Shirou could have watched the hero he had chosen do as they were instructed, instead he focused his attention on those who were watching the display. They were still skeptical and rightfully so, to them he was still a student, someone who had barely gotten his feet wet in the terrifying world around them. He could hear the first sword clank against the concrete pillar that the hero he had selected swung true, the weapon ineffective against the hardened material.

Thankfully the second was far more efficient.

"Thank you for your assistance," said Shirou, allowing the weapons he had crafted to fade away into nothing. "I believe that demonstration has just shown that indeed, two weapons are not the same."

Looking over his shoulder, Shirou took a momentary glance at the clean cut that had sliced through solid concrete as if it had been nothing more than butter. "As I was saying before however was that a hero has to be able to defend those unable to defend themselves. Ryuko, for this I will need your assistance."

...

Ryuko could hear the hushed whispers from around her as she felt her teeth grind together. To protect those unable to defend themselves was what she was being brought up for. Many in attendance wouldn't have thought much of the wording but she knew exactly what Shirou meant. Nevertheless, she stepped forward before standing in front of Shirou. "How can I help?" she asked professionally, doing her best to ensure this teenager did not get further beneath her skin,

"All I'm going to do is have you stand behind me," instructed Shirou. "I hope you don't mind."

"Not at all," said Ryuko, composing herself. It seemed as if he was going to shield her from harm and it seemed as if that since he was aware of her status as a member of the top ten heroes that in the worst case scenario, she would be capable of protecting herself. Knowing those in attendance, there were very few whom she would consider at her level of strength.

"Endeavour, would you mind assisting in this next part?"

That however, was not something she had been anticipating. She also had hoped that Endeavour's pride would prevent him from assisting what he likely thought as trivial. Sadly as he stepped forward with something reminiscent of a smile upon his lips she could sense that he only had malice on his mind.

"Now, I am going to go over there, far away from the spectators," said Shirou, gesturing to a point opposite to where the masses stood. "Ryuko, as my lovely assistant, will stand behind me. I take it that your fire will reach that point Endeavour."

"Count on it," grumbled the number two hero.

"Excellent, come now Ryuko," said Shirou, beckoning for the number nine hero to follow him.

For her part, Ryuko walked with purpose in her steps while internally she was scared beyond belief. Not only for herself but for Shirou as well. He had demonstrated and spoke of legendary weapons but nothing was particularly coming to mind in regards to any sort of weapon that had the ability to shield the wielder from fire. That wasn't even including her in the mix, how was a weapon that Shirou held meant to protect her from harm?

Stopping at the designated point, Shirou turned to face Endeavour. As Ryuko walked past to stand behind him, he could hear faint words being almost whispered from Shirou's mouth. "Do not fear, I will protect you."

Had her senses not been on high alert, she may have missed those reassuring words. That was truly what they sounded like. There had been no cockiness or bravado, it had been a simple fact. He would defend her at all costs.

Having felt her resolve uplifted, she took her place a handful of feet behind where Shirou stood. "Whenever you are ready Endeavour," stated Shirou as he stood calmly.

A handful of seconds ticked by as everyone in attendance watched on with baited breath. It was only after tensions were at their highest that Endeavour unleashed his power, sending a torrent of fire directly towards where they stood. For Ryuko, time seemed to slow to a crawl as she watched flames hot enough to melt skin from bone rush towards them faster than she had anticipated. Her eyes drifted to Shirou who raised an arm in front of him, directly at the flames which closed in on them.

"Rho Aias!"

In the last possible moment, she watched as a shield of light bloomed forth, the fiery destruction awaiting them crashing upon it and parting around them leaving them unscathed. Ryuko could only watch on in amazement, almost unable to believe what it was that she was watching as the flames continued to rain down upon the shield projected in front of them.

Eventually the torrent of destruction came to an end, revealing the pair unharmed to those watching on. Like the weapons beforehand, the beautiful shield too vanished from existence and Shirou was greeted with a round of applause from those watching. Endeavour did his best to not look insulted but Ryuko knew that a blow had been struck to his pride, even if Shirou had not meant it.

Ryuko watched on as Shirou stepped forward giving out his spiel for the next demonstration he was going to take, Ryuko couldn't help but look at the figure walking away from her. She may have just been sitting inside the top ten but with the future generations already making a stand, chances were that within a few years her ranking would plummet. Perhaps it was time that she spent some time to train once again and come up with some new ways to deal with any and all issues that stood in her way.

...

Shirou shook the hand of the last hero who had come to witness his demonstration, answering politely that he would consider their agency for the upcoming internships. As the doors to the gymnasium closed, Shirou turned to look at the last few people in attendance, namely the school faculty. "So, how did you think that went?" he asked modestly.

"I'd say you put on an admirable display," declared Snipe.

"If I may, I'd like to ask a few things about your power," said Nezu.

Shirou crossed his arms as he heard the wording that the mouse had said. Not once tonight had he said that his abilities in crafting weapons was the work of a quirk and Nezu had seemed to pick up on that. He sincerely doubted that it had been a simple slip of the tongue. "Go ahead," he said.

"Roughly how long does it take for you to look at a weapon for you to analyze it to such a point that you can recreate it?" asked the headmaster.

"As soon as my eyes lay contact on the weapon," said Shirou. "Though there have been some weapons that I have been unable to comprehend in the past."

"Oh, such as what?" asked Midnight genuinely curious.

"I cannot replicate firearms of any kind," declared Shirou. "There has also been a single sword my mind was unable to comprehend when I looked at it. No matter how long it remained in my vision, I couldn't grasp it's reality."

"Reality," repeated Ectoplasm.

"My second question," said Nezu bringing the train of thought back on track, "Is that when you mentioned legendary weapons you seemed almost defencive. Have you bore witness to any such weapon?"

"As Aizawa will attest, I have shown off one of Masamune's finest creations," stated Shirou. "When combatting Mirio, the stone axe I brought forth had been wielded during ancient times, well over three thousand years ago when humanity needed to be strong to survive."

"And you just happened to stumble across such a weapon?" asked Aizawa.

Well he had jumped in front of it and had nearly been cleaved in two by it but he felt no need to tell them that part of his history. "Stumble probably isn't the most accurate of words," he said sheepishly as he rubbed at the back of his head.

"Alright then, one final question," said Nezu coming to the crux. "Why did you never describe your ability as your quirk?"

Shirou's eyes picked up the subtle gestures that the faculty members made, almost bracing themselves for what he might do in response to that question. "You wouldn't believe me if I told you," said Shirou.

"I think we will be the judge of that," said Ectoplasm.

Shirou allowed a sigh to escape his lips before he turned to face his homeroom teacher. "Aizawa, would you be so kind as to use your quirk on me?"

Shirou watched as Aizawa's glare hardened ever so slightly and his eyes change colour, indicating that his quirk was in effect. Without hesitation, Shirou crafted a broadsword into existence and those watching couldn't help but allow their breath to get caught in their throats.

"I don't refer to my tracing as a quirk because quite simply, it's not."

...

Hope you enjoyed. PLUS ULTRA!
