...

Shirou looked out the window at the rain careening down outside, the dreary atmosphere completely opposite to the feelings of his peers currently in class awaiting their homeroom teacher. The banter they spoke amongst one another surrounded the fact of how they had been recognized by the populace for their performances regarding the Sports Festival. Had he actually stepped off the campus at any time that would be dictated as normal, he too might have been acknowledged for his actions. Since he only went out exploring through the cover of night, he was highly confident that nobody would have noticed him

The chaos in the room swiftly subsided as Aizawa stepped in, many of the students not wanting to get on his bad side so early in the morning. "Morning," he mumbled, paying little attention to the response that the students gave him in response. "This morning's hero informatics period is a little special. It's time to formulate your codenames, your hero names."

The students in the class exploded in enthusiasm and Shirou almost found himself covering his ears from the noise that assaulted him. It was understandable as to why they were excited. In this society it was evident that a hero whose name was recognized by the populace was a hero whom people could look up to.

Temporarily ignoring Aizawa as he continued, Shirou thought back to the names of the heroes that he had combatted against back in the Holy Grail War. While Berserker, Rider, Caster and the rest were the class they were assigned to and the title they were referred to as, it wasn't their name. Their names were still the ones that had been given to them by their parents. True it was a different dimension and a different time, but it was something that Shirou acknowledged as true heroism, simply to be known by their name and the actions they undertook.

"Now, the tally of nominations," announced Aizawa. "Typically the results are more balanced but this year it was clear where the attention was leading to."

Shirou couldn't help but scoff. There he was, at the top of the leaderboard with thousands of agencies wanting him to temporarily work under their wing. More likely than not it would just be to get some manner of prestige, to have the winner of the competition as part of their team even if it was for only a temporary measure of time.

Shirou allowed his eyes to drift to the bottom of the leaderboard where Midoriya sat with three nominations, despite the fact that he hadn't made it past the first obstacle. Clearly he had proven something in the brief period of time that he had had. There were some names missing from the leaderboard in general, students having missed out on making a statement to those watching.

"Based on this," stated Aizawa, his gaze drifting over the class. "Regardless of whether or not you received any nominations, I'll be having you go get some so called Work Experience. With that being said, the lot of you have already experienced far more than your peers and have taken a glimpse of the world of pros. But I think experiencing the activities of pros firsthand will be more fruitful training than before."

"And because of that we need hero names!" shouted Sato, pumping his fist.

Shirou returned his attention to the rain pouring outside of the window, barely caring as another member of the faculty entered the room and began pandering the importance of names. He really could not wait for this class to end.

...

Midnight continued evaluating the names the students of 1-A presented before her. Some had needed much alteration while others had been simply perfect. With the recently named Uravity returning to her seat, Midnight acknowledged those who had yet to present. "All that's left are Bakugo's revision and then the names of Iida, Midoriya and Emiya."

While Iida and Midoriya seemed to be overthinking their choice, she was worried to see that Shirou had yet to touch the whiteboard that had been handed out at the beginning. Ryoku's words from the other night rang in her mind once more. If he didn't have to be here, Shirou wouldn't be here. Why would he designate himself a hero name if he had no aspirations to become a hero?

The sound of a student standing up caused Midnight to shift her attention away from the student whom she was concerned about. Iida marched forward towards the front of the class in an almost robotic fashion. Once at the front, he turned to face his peers. "As many of you are aware, my brother, the hero Ingenium, was hospitalized from having faced a villain," he said, not showing his name just yet. "The initial reports indicated that he might never walk again and knowing such, he asked me to take his name. Last night I was left wondering if I could uphold such a legacy, to be the new Ingenium. Then this morning, we heard news from the hospital that a miracle had happened. My brother, who had had no feeling in his legs, was seen walking the hospital halls. We don't know how this happened, we don't know why and I don't know if I could have been able to take on my brother's name. With that being said, I will do my best I can be, as the Rapid Hero: Imperium!"

It was odd, far stranger than many of his peers who had stepped up before him to present their hero names. When a slow clap rang out however it was all worth it. Midnight herself had not even been aware that Ingenium had been administered to hospital, let alone with such devastating wounds. To hear that he was healthy once more was wonderful to hear.

Turning her attention back to the class, she watched as Midoriya walked forward having decided on his name. While he went on a spiel, explaining why he had chosen his name, her eyes focused once more on Emiya who seemed to be in his own little world. Chances were that he hadn't paid attention to a single name that had been delivered to the class.

As Midoriya returned to his seat, the name 'Deku' having been given for all to see, the rest of the class seemed curious as to what name would come next. A few curious glances were sent across the room as the students tried to catch a glimpse of what Shirou would produce. To see that he had yet to even touch his whiteboard which only caused some whispers to pop up.

"Hey man," said Kaminari, feeling the need to add a suggestion to Shirou. "What about Arsenal? I mean you're basically a walking armory."

This of course resulted in Kirishima chiming in. "Nah, Blacksmith would be much cooler."

"Please, he should be called Slice and Dice."

"What are you talking about? If Shirou is going to be called anything it's going to be..."

"Nothing."

"Nothing, see...wait, what?"

Mineta's current state of confusion was mirrored by the rest of those in attendance, whose curious glances were now direct stares at the person who had demolished the tournament the previous day. Allowing a sigh to escape his lips, Shirou turned his head so that he could address the students gaping at him. "The heroes I aspire to are known by the legend they left behind, heroes whose names will never be forgotten no matter how much time has passed," he explained. "I don't deserve to be acknowledged amongst the heroes of old and I will not sully their reputation by pretending to play hero."

His words struck like a knife and silence reigned supreme. There was a lot to digest out of what he had just said and it felt as if he was almost a different person, as if something had drastically changed in his life since after he had won the tournament. Then there was the mention of that despite his incredible power, he didn't even compare himself to the champions of a bygone era.

"Detention," declared Midnight, her gaze firm on the student in her line of sight. It was a harsh punishment in retrospect but she had her instructions from the higher up members of the faculty. She had been ordered to try and ensure that she, along with the rest of the members of staff available, would be able to break the news to Shirou in an environment where the rest of the students wouldn't be in harm's way. It was a worse case scenario but it was better to be prepared.

Now she had to brace herself for how Shirou would react to having been issued detention. Surprisingly he didn't act out, he didn't shout how unjust the punishment was and didn't even turn his attention back to the window. Instead, Shirou turned his attention to somebody else in the class. "Midoriya, you're in charge of training after class with Yaoyozoru's assistance in crafting anything you feel is necessary."

"Me? What? Why?" stammered Midoriya, clearly having not expected this in the slightest.

"You honestly think that you haven't been spotted mumbling after every training session?" said Shirou with a raised eyebrow. "It's time to stop keeping all of your notes to yourself and share some of your knowledge."

"Umm, yes, of course," said Midoriya, less than convincingly.

With that, Shirou turned his attention back towards the window creating a sense of unease amongst the students and faculty members. This of course was all shattered as Bakugo marched to the front and proclaimed that his hero name would be 'Baron of Explodo-Kills,' which understandably, didn't stick.

...

Stain was resting, perched atop the rooftop that he had been teleported to after negotiations broke down. Perhaps it had been for that reason that instead of finding himself back in his hunting ground of Hosu, he had been spat out here, wherever here was. It looked familiar but it wasn't as if he could wander up to the nearest travel guide and get some intel on the place.

This of course meant that he would get some information another way.

Scanning the horizon, focused eyes spotted another person standing atop a roof a little distance away. A female by the looks of things who looked as if they should have been sitting in class right about now. A wry smile spread across his lips as he started moving, curious how the woman he had spotted would react to his presence.

With speed and skill forged by determination and grit, the Hero Killer leapt from rooftop to rooftop with grace. Due to the layout of the city, he hadn't been able to take a direct route to his target but instead had had to circle around. Which of course meant that the following moments would be more entertaining as he landed on his target rooftop staring at the back of the woman whom had yet to move.

"Young lady, mind if I ask you a few questions?" he asked, awaiting the response he would get. It was oddly dissatisfying however that there seemed to be no sense of shock from the person that her personal space up here had been infiltrated. In fact, she only casually turned her head to acknowledge him and even then showed no signs of horror of the person standing upon the other side of the roof.

Maybe he was losing his touch.

"You may, however I don't know what answers I will be able to provide," they stated before turning their back on him once more. This of course, only served to annoy the person who had the blood of dozens of heroes on his hands.

Feeling irritated, Stain marched forward, the katana that he wielded upon his back now clutched in his hand. He wasn't going to kill the woman before him, she wasn't a hero who lacked conviction but some scare tactics in order to get the information he wanted seemed to be in order.

The blade of the katana thrust forward, deliberately missing her right shoulder by the smallest of margins. The speed of his thrust had blown several strands of hair away from the previous location and yet the woman didn't flinch nor tremor in fear from the weapon that so easily could have spilled her blood. Seemed that she had quite a bit of resolve.

"Now little lady, you will..."

That was all that Stain was able to say before pain surged through his body, every inch of his being feeling as if it was being struck by electricity coursing through his veins. The intense pain may have only lasted for a few seconds but he couldn't prevent himself from collapsing to his knees.

"Now that was rather rude of you now wasn't it," stated the woman who had not even turned to face him.

Grinding his teeth together, Stain tightened his grip on the weapon in his hand. He was feared throughout the land as one of the most terrifying villains out there. Nobody made a fool out of him! His weapon swung swift and true and as the tip of the blade threatened to pierce skin, his katana turned into sakura petals. His primary weapon, the steel he had utilized for so long, had turned into flower petals.

Still, he wasn't a renown villain for nothing and twin daggers swiftly found their way into the palms of his hands. Before he even had the chance to attack with them however he could only watch as the metal melted away, puddling at the ground just in front of him.

His mind swiftly went over a number of things that could be happening right now and divulged the theory that the person in front of him had a quirk that could reshape metal into anything they wished. It might have been a long shot and may have been well of track but in only a matter of seconds he had lost a good chunk of his arsenal and would likely lose more unless he got a handle on the situation.

Dropping the handles of his now useless weapons, Stain swung out with his fist just in the pure hope of dealing some manner of damage. In what seemed like pure luck, his attack struck true nailing the woman before him right in the lower ribs...only for him to retract his hand in pain, his knuckles feeling as if they had struck solid concrete.

"My, my, it seems you are out of tricks," they said, almost in a scolding tone before they moved, far faster than Stain had thought possible. A pair of arms found themselves wrapped around his waist before he was hoisted off of the ground, his torso still being clung to as he found the world revolving before his head crashed into the rooftop. A gurgled moan was all that escaped his lips before the Hero Killer found his consciousness slipping away.

The Hero Killer Stain, the man who had murdered seventeen professional heroes and crippled a further twenty three, had been defeated.

...

"I'm going to make the bold assumption this isn't how detentions usually go," said Shirou, crossing his arms across his chest as he looked at the members of the faculty standing before him. Had it been one, perhaps even two members of staff who were present it wouldn't have been surprising. Having half a dozen, including All Might, standing in line left him somewhat curious as to what he had done to deserve such treatment.

Standing atop the desk, Principal Nezu addressed the student standing before the faculty. "You're right, this isn't a detention in a traditional sense but we needed to speak with you privately," he said.

"You know you could have just come to my house and knocked on my door," said Shirou.

This only served to stir up Hound Dog who began to growl beneath his muzzle. Nezu spoke up again before his head of security did or said something foolish. "Be that as it may, we needed to discuss with you a couple of topics which would bode unwell to be heard by others."

Shirou's mind swiftly went into overdrive as he gathered some intel from the principal's comment that the diminutive figure likely hadn't intended to get out. "You think somebody's leaking details out into the public, or more specifically, villains," he said connecting dots together.

"That seems like a rather large leap in logic," declared All Might.

"Considering that attack that happened a few weeks ago, it really isn't," said Shirou before pointing at the number one hero. "The leaders even said that you were meant to be there according to the curriculum they acquired. Even on that day that the media got through the front door, they couldn't simply have wondered around the school for long enough to track down the exact piece of paper they were looking for. It got handed to them and you don't know who to trust."

"You were at the top of the list for a while," said Eraserhead, his gaze hardened on the person in front of him and prepared to activate his quirk at the first sign of trouble.

"I can picture that," said Shirou. "Sketchy background probably didn't help."

"Not to mention the fact that you clearly are more advanced than anybody your age," said Midnight. "Your skill with your quirk speaks of years of dedication to honing your ability to the best you could."

"Which is why we need to ascertain right now, just how strong you are," declared Ectoplasm.

"How strong I am," repeated Shirou. "Tell you what, why don't I show you? Tonight at eight in the gymnasium and I will show you just what I'm capable of."

The menacing smile that Shirou sent their way as he said that stirred some manner of fear into the heroes' beings.

"I'm sure that we will be there," declared Nezu. "On another bit of news, it would seem as if your friend missed class today and when we went to investigate her lodgings to see if she was unwell, it turned out that she wasn't there either. Would you happen to know where she may be?"

"Well we did have a bit of a falling out," admitted Shirou.

"Do you know anywhere she may have gone?" asked Midnight.

"If she has run off, then you won't be able to find her," declared Shirou matter of factly. "She'll return if she wants to but quite frankly if she wants to spend some time to herself I feel sorry for anybody who gets in her way."

"Regardless of where Miss Tohsaka may be right now, we have come to the conclusion that you will not be joining your peers working alongside the heroes in the weeks to come," declared Principal Nezu.

"Because I'm a flight risk," stated Shirou, reading between the lines.

"You catch on far too quick for my liking," said Eraserhead.

"If that is all, I might take this opportunity to see how Midoriya is running my class," said Shirou.

"I will accompany you," said Ectoplasm, the 'detention' effectively over and done with. Shirou merely shrugged his shoulders as he allowed the faculty member to join him. His mind meanwhile drifted off to Rin once more as he pondered just what she was up to right about now.

...

Stain came to slowly, blinking several times at the unfamiliar ceiling above his head. He tried to move swiftly but the aches and pains from his previous battle made his movements sluggish as he raised an arm to rub at the side of his head. This of course raised the very obvious point that he was unrestrained. Tilting his head to the side he found himself not caged in some prison cell, but rather a plain looking room desolate for everything other than the bed he was on.

He didn't know whether this was a good or a bad sign.

Pushing himself into a seated position, the door to his temporary accommodations opened up to reveal his captor, smiling sweetly at him. "Good, you're awake," they said. "I need you to tear down some walls, install a window, pick up some groceries..."

"Just who do you think I am!" growled Stain, his aura pulsating out as he tried his best to intimidate the person standing before him.

To absolutely no effect.

"Why," said Rin coyly, the smile not leaving her face, "You're my little errand boy of course."

Stain had a terrifying feeling that being thrown in prison would have been a better alternative to whatever it was this woman had planned for him.

...

Hope you enjoyed.
