Author's Note: Hello all! New chapter, a little longer than usual, but before we get started on that I wanted to clear something up. I recently received a review that made me realise I'd left a few things a little ambiguous and maybe made the Justice League seem incredibly incompetent when contrasted with Class-E and I just wanted to say that that was not my intention.

I've implied in previous chapters that Koro-Sensei has gone up against the Justice League, both dealing with individual members on a one-on-one basis as well as the team as a whole, but what I only ever made clear was that Koro-Sensei escaped from these altercations unscathed and not how exactly that came about. What I wanted to make clear was that Koro-Sensei is not beating the League so much as he is evading them. Koro-Sensei's speed, invulnerability and healing factor enable him to survive conflict with the League largely by surviving whatever they throw at him and then just leaving. He doesn't do much to them and he makes sure they can't follow him. Theoretically, if he were cornered, the League could beat Koro-Sensei, but they can't contain him and don't know how to kill him and therein lies his advantage.

E-Class then has the advantage because Koro-Sensei willingly nerfed himself by voluntarily tying himself to the classroom. Not only did he swear not to fight back against the students and offered them the chance to study him for a way to kill him, but he also stripped himself of his greatest survival technique: running away. He refuses to leave the classroom during school hours on principle because he is a teacher and teachers don't do that.

If the Flash had done what Wally had done in the last chapter, Koro-Sensei would've been out the window and into the air, but because class was in session, he wouldn't and couldn't leave.

Anyway, I hope I've cleared that up. Let me know what you think of the latest chapter.

Wally spent the next few hours in something of a daze, wandering and running on and off and without direction as he questioned his current purpose in life. He was a superhero. He saved lives. He stopped bad guys before they even knew what hit them and he always did his best to see that everyone got out okay.

And yet, Koro-Sensei had been his mission. He had accepted the duty to kill this living, intelligent, absolutely insane being. He had tried to do just that, and he had failed.

The power of hindsight is a marvelous thing, but right now all it was doing was showing him what he should not have done with no thoughts as to what he should do now.

Obviously, he should have waited. Koro-Sensei's deadline wasn't for another eight months, so it's not like he didn't have the time. He could've sat in that classroom and made sure he knew all of Koro-Sensei's tricks before he went and made his move.

And now he learned that speed was of even greater importance than he'd ever thought. If Koro-Sensei had even the slightest inkling that an attack was coming, apparently he could turn completely indestructible at will.

But he'd been impatient. He'd wanted to get back to his life. He'd wanted to leave Kunugigaoka as soon as humanly possible.

Maybe Wally could force Koro-Sensei to change again when the Lanterns were back in the solar system...? Hal and John could send him into a black hole or something. See if he comes back from that.

But Koro-Sensei was going to be wise to the trick. And, as Nagisa had well informed him, Koro-Sensei never fell for the same trick twice.

And, in the meantime, Wally was going to be stuck in that class. Well, actually, the class wasn't really the problem. He was going to be stuck in that school. And his parents were still going to think he was a delinquent... no, actually, screw that. Batman would let him let his parents in on the secret and, in exchange, Wally wouldn't throw him under the bus when it came time to explain themselves to Dick.

Wally shuddered at the very thought of that. Dick was not going to be happy at the way he'd left things. Good thing there was an ocean between them right now.

Casting aside such gloomy thoughts, Wally turned his eyes to the heavens above, his gaze catching on the crescent moon hanging in the sky. It was beautiful up there, despite the hole. Not for the first time did Wally wonder exactly how Koro-Sensei had managed to blow it up in the first place.

His thoughts once again returned to Koro-Sensei, Wally found himself wondering what exactly the League was doing to him right now. Had they tried Canary's cry? If she managed to hit the right vibrational frequency, Koro-Sensei could well shatter.

What about Zatara's 'magic'? Maybe J'onn would be able to get inside Koro-Sensei's head? Or Captain Atom... maybe nuking him really was the solution?

Ugh. Knowing Koro-Sensei he'd laugh it all off. Wally didn't much doubt that he'd be back in class tomorrow with a smile on his face. Come to think of it, Wally had yet to really see a smile not on his face... except for today.

Wally could feel his face drawing pensive, which he hated. Brooding about the mysteries of the universe was a Batman thing. Flashes were meant to laugh it all off.

But, for a moment there, when Wally had made his move... Koro-Sensei hadn't been smiling.

Wally had seen him laugh off everything E-Class could throw at him in his little indestructible shell. Wally had seen him laugh off just about everything without that as well.

But for a few split seconds when Wally had attacked today, Koro-Sensei had been scared. Scared for his life. So that 'Ultimate Defensive Form' of his wasn't a reflex. For a moment there, he had been vulnerable.

If Wally could just catch him off guard again, this time without the surprises and the mistakes and the hesitation, then Koro-Sensei really could be killed.

That, at least, was a happy thought. Wally's eyes shifted from the moon as he habitually sought out the little speck of white in the sky, a touch brighter than any of the stars, that signaled the Watchtower, only to frown when he realized that the constellations he was looking at most certainly did not match those found in the skies of Japan.

Wally was brought screeching down to Earth as he came to a startling realization.

When the hell did he get to Africa?

Wally walked to into Kunugigaoka Junior High the following morning with all the enthusiasm of a young child on their way to their very second day of school. That is to say, he was sullen, moody and depressed, with the large majority of his hope and optimism having been soundly beaten from him the previous day.

Since Clark had bailed on him, taking Koro-Sensei off to the Watchtower, Wally had not heard word from any of the Justice League. Dick had buzzed him five times now in search of answers, but Wally wasn't going to risk telling him anything without the Bat's approval, which only served to worsen his mood.

This did have one advantage, however. As he entered the school grounds, Wally drew the attention, as he often had in the past several days, of some of his former classmates from D-Class.

These classmates took one look at Wally this morning and, in a surprising fit of self-awareness, had wisely decided not to engage him on this day. However subconsciously, a portion of their minds recognized the look of someone in a mood so foul that they were beyond caring of the consequences, for truly nothing could make them feel any worse.

It was a dangerous and unpredictable state, and the D-Class students were wise to recognize and avoid it.

The same could not be said for the students of C-Class. They were at a perfectly imperfect point of the hierarchy, just arrogant enough to believe that a student of E-Class would never really try anything against them, but insecure enough of their positions that they still felt the need to prove it.

Wally noticed a trio of individuals blocking his path and looked up, finding three boys with relaxed features and found himself halting, his frown only deepening.

When Wally arrived at the dilapidated schoolhouse, he was smiling.

Then he came face to face with Karasuma, a single eyebrow arched dangerously.

Wally met his eyes, doing his darndest not to look away.

"So, tell me honestly," he broke the silence. "When did you have me marked as an assassin?"

"Everyone in this class is an assassin from the moment they enter, Mr. West," Karasuma replied blithely. "But, if you are referring to your abilities, I was aware you were limiting yourself in P.E.. I trust that that will no longer be the case?"

"No sir," Wally nodded. "Actually, if you don't mind, do you think I could say something to the class before we get started this morning?"

"Well that depends," Karasuma eyed him curiously. "What exactly did you have in mind?"

Karasuma watched the boy smile broadly.

"Myself, of course. What else?"

The students of E-Class weren't particularly surprised when Koro-Sensei didn't show up for school. According to Nagisa's watch, his 'Ultimate Defensive Form' wouldn't revert for another three hours. They were a little surprised when Karasuma-Sensei gave Wally the floor.

Standing before the class, many of them noted the difference in the way that he carried himself when compared to how he had first appeared to them. Where before he had stood before them nervous and uncertain, hiding behind a veil of arrogance, he had since dropped the façade and was now confident and self-assured. The act no longer required now that his assassination had failed.

He stood before them no longer hiding his abilities or himself. They were now aware that, perhaps barring Ritsu, he was likely the most dangerous of their classmates. And he knew that they knew. It was a strange feeling.

And it made more of a difference than you might think.

"So," West said, clapping his hands together in lieu of a proper greeting. He stood at the center of the blackboard, almost exactly where he had been when he made his first lackluster attempt on Koro-Sensei's life. "I'm guessing you've all figured it out by now but, for the record... I am Kid Flash."

The confession that could've made papers the world over was met with blank stares.

"Get to the point, idiot," Terasaka told him bluntly.

"I know what you're thinking," Wally offered. "And I'll answer all of your questions. Firstly; yes. Wally is my real name. When I was assigned to infiltrate the class, we knew that a Koro-Sensei would pick apart any false identity in minutes. Second; also yes. I am faster than Koro-Sensei. Third... actually that was all I had. What else do you want to know?"

The stares continued. Waly squirmed, uncomfortable under the combined gaze of 25 odd teenagers. He'd never been great with crowds.

"Have the Justice League had killed Koro-Sensei yet?" Yada was the first to break the silence.

"I haven't heard a thing from them since Superman took off," Wally admitted. "So I doubt it."

Nagisa raised his hand. "Will they let us see the notes from their attempts?"

Wally blinked dumbly. "Probably not. The League likes to keep that kind of stuff under wraps, but I'll see if I can't get someone to hack their security feed for us."

Nagisa nodded, satisfied by the promise of further data.

Fuwa leaned forward, her eyes shining intently. "Does this mean your dad's the Flash?"

"No," Wally told her bluntly, before addressing the class as a whole. "And, while we're on that subject... no. Don't ask me anything about who the League really are. I won't tell you anything, and if I do, it will be a lie. Moving on."

"Are Superman and Wonder Woman dating?" Nakamura asked.

"Moving on," Wally insisted. Nakamura grinned.

"What about Superman and Batman?"

"I said moving on!"

"Now," Wally did his best to follow his own advice. "We've got a chance to talk without Koro-Sensei popping in on us and I wanted to show you that Koro-Sensei is more vulnerable than he lets on."

"Nagisa," he pointed out the boy in question. "Could you please read off Koro-Sensei weaknesses numbers 2 and 7?"

The pigtailed boy furrowed his brow in confusion, but dutifully recited the items in question."Koro-Sensei is surprisingly quick to panic and has no patience for wire puzzles. What of it?"

"A little known fact about speedsters is that we see time differently than most people," Wally explained patiently. Blurring into motion, Wally's form was a vague haze that settled almost immediately and the students in the front row were startled to discover origami effigies of what was likely to be their teacher upon each of their desks. Tapping at his watch, Wally explained, "According to this, that took about five seconds. But to me it felt like five minutes."

"Patience is something we're good at because we've always got more time than we know what to do with. But it's also something we need to learn," he insisted, bringing the discussion back to his point. "And if Koro-Sensei hasn't learned it yet then I think he might be a lot newer to his abilities than we thought."

It had never been much of a secret that Koro-Sensei had once been human. He had made clear from the beginning that he was not an alien and understood human culture far too well to have been raised in isolation, so the only question remained was when he had gained the inhuman qualities that he had become so proud of.

Many of the students had made the assumption that Koro-Sensei had been living with his form for the majority of his life, if only due to the casual ease with which he disregarded humanity and appeared to hold such mastery over his own biology. But if what Wally said was true, then Koro-Sensei as they knew him may have emerged only in the weeks before the decimation of the Moon.

Which to Wally meant exactly two things. The first was that Koro-Sensei may still have tricks up his sleeves that even he wasn't fully aware of. The second was that the same was also true of any potential weaknesses.

Much of the morning was spent with the students of E-Class furthering their own pursuits. Karasuma-Sensei considered it a reward for their efforts the previous day and a time of personal reflection. Bitch-Sensei simply couldn't be bothered taking the class.

For the more studious amongst them, this involved preparation for upcoming midterms. For the more determined, it meant plotting new ways to kill Koro-Sensei. And for the majority of them, it meant talking freely with amongst themselves about both these subjects and many others.

All of these ceased the moment Koro-Sensei arrived. He was a little later than expected, and his robes were a touch scorched, but overall he seemed no worse for wear and, judging from the smile on his face, he was feeling just peachy.

At least fifteen hours taking everything the full might of the Justice League could throw at him and he was just peachy.

An odd noise filled the classroom, caused by the collective grinding of the entire class's teeth.

"Well, I'm happy to be here," Koro-Sensei muttered snootily, turning his nose up to the class (metaphorically of course). An array of tentacles unveiled themselves from his robes, each carrying a stack of papers. "And you'll be happy to know that I fully intend to see you all make up for the time we lost yesterday. So, if you could all just pass these around- each quiz has been personalized and marked with your name."

Grudgingly, the students did just that, sorting through the pile before them for their own booklet before passing it on. Koro-Sensei was their target and they'd just spent a full day unified in their attempts to kill him... but he was still their teacher. And class was in session.

The papers were slowly distributed and, personalized as they were, most of the students found themselves with a small quiz that ranged in length between 3 to 8 pages depending on their current level, each varied in subject matter and difficulty.

Only Karma and Wally broke the pattern. Karma having a full 12 pages worth of questions sitting before him and Wally having absolutely nothing.

Looking around awkwardly, idly wondering if his test was simply hiding in Karma's booklet, he began to raise his hand, only to jump when Koro-Sensei appeared at his desk, slamming an object on to his desk with a heavy 'thump'.

Wally stared slack-jawed at the book placed beside him. A4 sized paper, the book was as thick as a dictionary. His name was written at the top of the first page.

Wally shifted his gaze up to Koro-Sensei's smiling face, a little bit of fear shining through in his eyes.

"I know it seems like a lot, Wally," the teacher grinned. "But after seeing what you've been holding back yesterday, I think it's time we really started giving you a challenge, don't you agree?"

Wally's eyes narrowed. It was something of a flaw in the heroic line of the Flash that all speedsters seemed to share an innate inability to back down from a challenge.

He set his jaw. He picked up his pen.

Addressing the class, Koro-Sensei declared it time to begin. "You have thirty minutes."

For the first two minutes the students made a genuine go at the quizzes placed before them. No matter Koro-Sensei's eccentricities, they had learned to trust him as a teacher and were certain that the tests had been designed to help them with only a slight percentage (maybe 12% at most) of their existence being due to petty vengeance for the previous day.

So they knuckled down and started to work through the first questions. Some, like Okuda, attacking at speed brought about by panic, their own pace working against them as they missed vital information when reading the questions, resulting in answers that were, though technically accurate, were also hopelessly incomplete.

Others, like Terasaka, read at a far more relaxed pace (due largely to not caring whether or not they succeeded). Taking their time, they were able to determine the full measure of the questions, but, lacking the motivation or the drive, their answers were broad and lacked specificity.

Most students had moved on to their third question, with only a few still stuck on their second, when their keen senses began to note an anomaly in the air. That being, the sharp scent of smoke.

In a wave radiating from the back of the class, students began to turn to seek out the source the moment they detected the acrid aroma.

The source was Wally, a thin trail of smoke rising slowly from the yellow blur that was his #2 pencil. He was already a good quarter of the way through his stack and showed no signs of slowing down.

Almost as one, the students glanced from Wally to Koro-Sensei, in order to see what their teacher was making of this.

Judging from the frown, he wasn't too sure either.

With a collective shrug, the students turned back to their papers. Wally's display was interesting and all, but it wasn't going to help their grades any.

Five minutes left on the quiz and the students were back to staring. Their papers lay on their desks, unfinished and forgotten as the display took up their collective attention.

Wally knew they were staring, but that was okay. They may not have been his intended audience, but this was still a show, after all.

This was a message. For Koro-Sensei.

His pencil raced across paper, filling out bubbles and writing out answers wherever needed. Whenever he reached the end of a page, it was ripped away from him, only to be replaced by another. This one with questions more difficult than the last.

He'd finished his quiz early, you see. Koro-Sensei couldn't stand for that. Couldn't admit that he'd underestimated his student's abilities. So he'd given Wally more. And Wally finished that too.

And so it had become a race, of sorts. Koro-Sensei crafted questions, trying to do so faster than Wally could answer them. He'd had a bit of a head start, but Wally was gaining fast.

Wally was making a statement, now that he couldn't hide it. He could move faster than Koro-Sensei, that was a known fact, but now he was proving that he could think faster too. He'd give the octopus a reason to be scared. He'd show him how fast he really was.

And as the clock finally ticked over, with Wally having finished his final sheet before Koro-Sensei could replace it, he truly did.

For many of the students, the remainder of the day passed without major incident. Already having given up on the school day for regularly scheduled classes, Koro-Sensei declared the remaining class-time as an intensive study session, creating and maintaining his speed duplicates in order to give each and every student the attention they required for their personal tuition.

Of course, not everyone gave their full attention. Despite the insanity of the past day, there were still looming threats to steal focus.

Sugino, for example, was idly wondering if the class's recent training in assassination could possibly help them make a decent showing at the school's annual inter-class baseball tournament.

Nagisa's thoughts had turned to considering Wally's speed. He considered the possibility of E-Class training against him, using him as a testing ground for new assassination techniques. With his speed and intelligence, he might be the perfect stand-in for Koro-Sensei.

But, for the most part at least, focus was returned to the upcoming midterms, and the class passed with at least some degree of productivity.

And when the final bell for the day rang clear, the students didn't really give it much thought that Wally was asked to remain behind.

They filed out, beginning their trek back to the main campus just so they could head home. Wally, meanwhile, made his way to Koro-Sensei's desk.

He moved, deliberately slow, his eyes glued to Koro-Sensei as he tried to gauge some kind of reaction. He knew Koro-Sensei was impatient, but the exact extent had yet to be determined.

Koro-Sensei did not offer any answer. He merely sat at his desk, a pair of tentacles folded before him as the rest were stashed away under the desk, giving him at least the basic outline of an ordinary man should one ignore the sheer size of his head.

"Take a seat," he gestured softly at the empty space before him. Wally grabbed Isogai's and shuffled it into place, lowering himself into the chair without much thought. Across the desk, Koro-Sensei leaned in intently.

"You are a very interesting young man, West Wallace," he spoke simply and without malice. His tone no different than if he were stating any other fact. "And I have to wonder... why exactly are you here?"

Wally arched an eyebrow. "I kinda thought that was pretty clear by this point?"

"Well, yes, to kill me, obviously," Koro-Sensei nodded, dismissing the thought with an offhanded gesture. "That's why you're in Japan. But what I mean is, why are you still in high school to begin with?"

"Clearly you're intelligent enough to do away with the whole institution," he continued, not giving Wally the chance to do no more than smirk softly. "You're smarter than I thought, actually. Judging from your records, I knew you were bright. But I had assumed that was merely for your year level. But it's far more than that, isn't it?"

"You really are a genius, aren't you?" Koro-Sensei smiled. "I wonder, how much of that is your natural abilities, and how much is being enhanced by your unique perception?"

"First one, then the other," Wally shrugged, but his face spoke not of indifference. He was proud. Smug. It wasn't often he was really praised for his intellect and it felt good to get some recognition. "I figured out how to give myself superpowers when I was thirteen. What'd you expect?"

"I expected that I would teach all of my students the sanctioned curriculum, but it's clear that that would be a waste of time for you, wouldn't it?" Koro-Sensei mused. "Well, except for Literature, that is. Your essay skills clearly haven't received the same attention as your other subjects."

Wally shrugged. Literature was the one subject where his phenomenal recall did little to aid him and his interest waned. He could quote Shakespeare word for word should the need arise, but analyzing it was an entirely different beast.

"So what I'm curious about is, why haven't you already graduated?" Koro-Sensei asked him straight. "You could be well on your way to a doctorate right now- probably several, actually- but here you are sitting through lectures that must bore you to tears."

Wally shifted his gaze, suddenly uncomfortable with the line of questioning, but still unquestionably defiant. "You're not getting rid of me that easily. I can tank any test you give me to try and get me to graduate early. And besides, my parents wanted me to do school the normal way. Something about 'making friends' and 'socializing' and stuff."

"Which went wonderfully, I'm sure," Koro-Sensei's response was dry and humorless. Judging from the reports, Wally hadn't had a single friend back at Central City High. "Wally, I have no intention of having you graduate out of my class. Well, at least not before the school year is over. No, I think, however counterintuitive it may be to my own survival, this class may be the perfect place for you."

"Here, in this class of assassins, where everyone already knows the truth about your dual life, your speed and your intellect... you might actually manage to make some friends."

For a moment, silence reigned. Koro-Sensei waited patiently, and perhaps a little smugly, for Wally to process and properly react to his statement.

Wally, for his part, tried to figure out whether Koro-Sensei was genuinely concerned for his social development or if he was just taking an easy shot at him.

"I have friends," he stated bluntly, deciding that he was just being insulted.

"Kid Flash has friends," Koro-Sensei corrected, pulling a photograph from his desk and showing it to him. It was a shot taken from a camera-phone of himself, Robin, Kaldur and Superboy after the breakout from Cadmus Labs. Nothing on any of his more recent teammates. They'd since gotten a lot better at stealth. "Rather interesting ones, too. Is Superboy really the child of Wonder Woman and Superman's? He seems a bit old..."

"Hybrid clone made from Kryptonian and Human DNA," Wally replied without thought. "And Wonder Woman digs Batman."

"What? How does that make sense?" Koro-Sensei frowned. The Superboy tidbit was interesting and the blogs would have to be informed, but the Justice League shippers were not going to be happy with the second revelation. "Clearly she belongs with Superman! Batman's human! He'd... break."

Wally cringed at what his teacher was implying, willing for just that moment to trade away everything he had just to get that image out of his head. "Never say anything like that ever again!"

"Or what?" Koro-Sensei gave a sardonic smile. "You'll kill me?"

"Don't tempt me."

"Heaven forbid," Koro-Sensei waved him off. "But, back to the matter at hand... I won't be recommending you leave my class, Wally. I may not have much to offer you academically, but I can think of no better place for you to continue your social development."

"My 'social development' is just fine," Wally snapped. "I have friends! I made friends in this class before they even knew who I was!"

"Yes, and let's look at those, shall we?" Koro-Sensei replied coolly, before listing them off on his tentacles. "Okuda, Nagisa and Karma. All of whom possessed knowledge or skills that you knew you could use against me. You didn't make friends. You made allies. Since you arrived in this class you haven't done a single thing with anyone here outside of school hours."

"You ingratiated yourself with those you knew might be useful," he concluded. "And whilst it was an intelligent tactic as far as your assassination went, such subterfuge is no longer necessary. You only have about eight months left, Wally. Live a little."

"I will kill you," Wally told him.

"I sincerely anticipate seeing you try," Koro-Sensei responded. "But now that I know your tricks, you'll have to be a lot more creative. And you'll need friends by your side, not just allies."
