Author's Note: Hey, Chapter 2 here. Not much else to say, but let me know what you think.

There was a charge in the atmosphere of the classroom when the new student stepped in.

Nagisa could see it clearly in the green eyes that were drawn to Koro-Sensei's fluorescent yellow skin and in the tightening lines of his face. He must've been briefed by the Ministry of Defense, as they all had, and had seen pictures before. But now, seeing Koro-Sensei standing before him with that smile on his face... it was a whole new level of fear to be experienced.

West's hand fell immediately to the handle of the knife at his side, resting it there as if drawing comfort from the weapon.

Nagisa wasn't the only one watching West. Everyone watched with baited breath for his reaction.

"So, you must be West-kun," Koro-Sensei smiled as genially as he was able, but that only served to unnerve his newest student further. When Koro-Sensei smiled, he tended to show an awful lot of teeth and that was never a useful component when trying to convey a calming presence. "I, as I'm sure you're aware, am Koro-Sensei. Welcome to Class 3-E. I hope you have a productive year!"

There was the briefest hesitation, before West nodded weakly, looking a little sickly as he breathed. "Sure..."

Maybe it would be Karma who won the pool after all. He'd put money on the new kid fainting.

"Now, why don't you come up here and introduce yourself to the class," Koro-Sensei offered a bulbous yellow tentacle to West, waiting patiently as he smiled. West stared at it, his gaze shifting from Koro-Sensei's face to the proffered limb with fear in his eyes.

But, slowly, he nodded, stepping forward and taking a stand at the center of the blackboard. His back to Koro-Sensei as he looked out at his new classmates.

He flinched when Koro-Sensei's tentacle rested on his shoulder, in what Nagisa was sure was meant to be a comforting gesture. West's instinctively reaching for the knife but again failing to actually do anything.

Maybe Nakamura would win after all? Poor guy was absolutely terrified, but didn't seem to have the resolve to at least make an attempt on Koro-Sensei's life. Which Nagisa supposed he understood. Koro-Sensei's inhuman appearance alone was intimidating enough, but the fact that he stood twice as tall as his students didn't help any.

And the fact that they knew he'd blown up the moon? Well, nobody wanted to attack someone they knew to be so much stronger than themselves.

"Hello..." West's voice wavered. His accent immediately clear and marking him as an American, even if his records hadn't already given him away. "I'm, uh... I'm 'West Wallace', but, uh... feel free to call me 'Wally'. Heh, it's kind of weird always being called by my last name..."

There was a class wide twitch. The unintended insult to the Japanese naming system was taken in stride as a foreign quirk. But still, it was... odd to try and put yourself on a first name basis with an entire classroom of people you didn't even know.

"Well, I'm from America," his hand moved to brush through his short red hair, his eyes darting around the room, shining with uncertainty. "From Kansas, actually."

"Oh? That's interesting," Koro-Sensei leaned over West's shoulder as he interjected. "I've spent quite a bit of time there. That Superman is such a friendly fellow, you know. A little slow though..."

West froze in place as a portion of Koro-Sensei's weight settled onto his shoulder. But then he did what everyone in the class had been waiting for.

He moved. And his audience watched.

His reach for the knife was... inefficient. He wasted precious time and energy by darting for the handle rather than starting the assault with his hand already in position. He'd alerted Koro-Sensei and the entire class to his plans before he'd even reached the blade.

And then his attack... Koro-Sensei at least allowed him to turn and face him head on, but he didn't go for a lunge or a stab. He slashed.

Nagisa winced at the execution. Even if it had landed, it would have been a shallow wound. A complete waste against someone with Koro-Sensei's regenerative capabilities.

Of course, he didn't even get that far.

Koro-Sensei backed out of reach rather than stopping the assault cold. He wanted to see West's best efforts. And West obliged, lunging in for the stab that should have been his first strike.

It didn't land. West found himself lifted aloft, his arms held above him by Koro-Sensei's tentacles and the knife falling from his slackened grip.

No one, bar perhaps West himself, was surprised. It was an amateur assassination, no better than any of their first attempts.

It was okay though. He was here to learn, after all.

Still, the demonstration was important not just for West. Not only did he learn that Koro-Sensei would require a far more fantastical assassination plan than 'hack and slash' in order to be done in. But the students also learned a valuable lesson.

They had the chance to see how much they had improved over the past three months.

And perhaps that was Koro-Sensei's intention.

"Sorry, Wally," Koro-Sensei at least had no problems referring to West by his given name. "But I'm afraid that if killing me was that easy, it would've been done long ago. You'll have to do better next time."

Koro-Sensei released him to the ground, before politely pointing out a vacant desk at the back of the class. Shuffling nervously down the aisle, keeping his eyes on Koro-Sensei as he backed his way along, Wally shortly made it to his desk, just behind Okuda.

To his right, Karma smiled as he sat.

"Don't worry, Wally," Karma said the other boy's name with a teasing lilt. "Koro-Sensei's a big softie. Killing him'll be a cinch once we figure out how."

Once the introductions were cut short and done away with by the failed assassination attempt, Wally was soon subjected to the surreal experience of being taught science by a giant yellow octopus monster.

Well, 'taught' was a strong word. Wally had a working understanding of chemistry and scientific procedure and the grade at which Koro-Sensei was teaching was far below him. He was being lectured on science by a yellow octopus monster.

With Koro-Sensei distracted, Wally's thoughts quickly turned to review. So far, things had gone off without a hitch. Playing the weak little nerd was a specialty of his, honed and mastered back in Keystone City to keep any would-be Hero Hunters from finding Kid Flash's secret I.D.. The arrogant coward aspect of the facade was a relatively recent addition.

Back home, he was the good little nerd who never spoke out of turn. Mostly because he didn't really have any friends. Here in Japan, he'd quickly turned delinquent in order to push his teachers into dropping him like a hot potato. Not scared in the slightest by academic failure or a stern lecture, but put the prospect of physical pain before him and Wally could set his knees knocking with the best of them.

He needed to make sure that Koro-Sensei didn't see him as a threat. Make him let his guard down.

Wally would play the fool for a week or so, maybe try another assassination or two to cement Koro-Sensei's ideas of his physical capabilities. And then, when he let his guard down, he'd strike and put Koro-Sensei's Mach 20 speed to shame.

It was just a matter of time.

As the first day dragged on and lunch soon arrived, Wally kept a close eye on both his target and his fellow students.

He was starting to believe he'd been severely misinformed about the nature of this mission.

The main campus building was flush with rumors and horror stories about Class 3-E and, even after dismissing half of what he heard as baseless gossip, he'd still come to the conclusion that the students of the End Class were either psychotics, delinquents or idiots. Sometimes even some feral combination of the three.

Just from his seat at the back... Karma was quite possibly psychotic (he enjoyed the thought of assassinating a teacher way too much) and Terasaka was both an idiot and a delinquent. But as far as he could tell, the rest of the students were pretty much normal.

A couple of oddballs here and there, but nothing really out of the ordinary. Other than the fact that the class had to be going through about a dozen bottles of hair-dye a week. No way in hell were some of those colors natural.

And their relationship with Koro-Sensei... When Wally had first heard of the 'Assassination Classroom' he had pictured constant and relentless attempts on the tentacled creature's life. After all, here was the thing that planned to destroy the Earth! And there he was, right in arms' reach... and nobody was taking advantage.

"Well, yeah," Karma had told him with a nod when he asked. "I guess, but, come on... exactly how well did that go for you again? Koro-Sensei expects things to go down in class and he's way too fast for us to do anything other than waste time. And, I don't know if you noticed, but some of these kids need all the help they can get. Interrupting class time isn't exactly a great way to make friends around here."

"Such actions are disruptive to the learning environment, and Koro-Sensei has requested assassination attempts be restricted to personal time whenever possible."

Wally flinched at the sound of 'Ritsu', the automated weapons system that was mounted two seats to his left. Designed quite literally as a killing machine, Koro-Sensei had programmed the bubbly personality of a high school girl into its circuits. The result was a cyber girl with an innocent face that could kill anything and anyone it chose... except for its original target. Although Wally had been assured that 'she' was working on it.

It had taken a single conversation for Wally to decide that she seriously creeped him out and to do his best to carry an EMP generator at all times in case someone ever decided to send the thing after him. Or in case she decided to take over the world. Wally figured there was a better than decent chance of that happening at some point in the future.

But it was as they were discussing such previous attempts that Wally raised the question. "So, other than these weird knives, does he have any weaknesses?"

"A few," Karma shrugged. "Okuda's been trying to work out a couple of poisons that should have an effect on him, but the one you want to talk to is Nagisa. Kid's been taking notes on everything that sets Koro-Sensei off. Keeps a notebook about it."

Wally quickly decided that he and Okuda would need to compare notes in the immediate future, but his first priority would have to be getting a look at that notebook.

"Yeah?" He kept his voice calm. Casual. "Which one's Nagisa?"

"Blue hair. Pigtails." There really wasn't much else needed to narrow it down and Wally's eyes zoned in on the student in question, analyzing carefully from the back of the class.

"Think she'd let me take a peek if I asked nicely?" He asked offhandedly, his eyes never leaving Nagisa's desk, where he could see the pigtailed student hard at work jotting something down in what Wally could only assume was a veritable cornucopia of intel that had not yet made its way to the Ministry of Defense.

Had Wally been looking in Karma's direction, he would have been able to see the malicious gleam appear in his fellow redhead's eye.

"I don't know," Karma replied airily. "She plays it pretty close to the chest. But she does have a thing for redheads- we even used to have a thing- so you might have a shot there if you butter her up first."

"Really?" Wally smirked confidently. He had recently found that combining 'new student' with 'country bumpkin' and 'innocently ignorant foreigner' gave you a lot of leeway when talking to girls. He was reasonably certain he could sweet-talk his way into some intel. "You don't mind?"

"Nah," Karma waved him off. "She was too much of a tomboy for me. Wears trousers instead of skirts, you know? Good luck to you."

Karma was a cruel cruel boy, he thought to himself as he watched Wally eye his friend confidently. Really, it was a wonder why Nagisa put up with him.

Koro-Sensei kept a close eye on Wally during the sixth period study session. The new transfer student seemed to have struck up an easy dialogue with both Karma and Okuda, which he supposed was a good thing. Wally's transcripts suggested that his grades could surpass even the Chariman's son in most subjects, but he had trouble communicating effectively with his peers and had poor behavior. New friendships in a new classroom could be just the thing he needed to turn himself around.

Although, judging from the light shining behind Okuda's glasses, Koro-Sensei suspected they may have found themselves another assassin with a knack for chemical warfare, in which case he supposed he'd have to keep a close eye out.

Things could well get bumpy in the next few days with the class's latest assassin joining the mix. Oh well. A pity he'd already lost the month's molting to his little confrontation with Itona. Koro-Sensei supposed he'd just have to keep his guard up.

And besides, it would be good for his students to take on the role of teachers regarding their newest classmate. Wally would need their guidance in order to catch up and become a competent assassin.

When classes ended for the day, Koro-Sensei disappeared without much preamble. Apparently there was a basketball game to be caught in L.A. and not much time to catch it.

The students began the long walk down the mountain together at first, splitting off bit by bit as the faster students outpaced the slower ones or friends chatted and stopped for a break.

Wally spent much of the walk continuing the discussion he had begun with Okuda. He was intrigued by the girl's love for chemistry, having met few people in life who could rival his own. She had already attempted to poison Koro-Sensei with a few different chemical combinations and had kept detailed notes on what the effects had been.

Learning that Koro-Sensei had proved unaffected by Aqua Regia and Hydrogen Flouride was more than a little disheartening.

"What is he even made off?" He exclaimed, after learning that Koro-Sensei had guzzled these acids and commented only on their poor flavor.

"I'm not entirely sure," Okuda admitted shyly. "I've been trying to determine that by working backwards. Seeing how different acids react to him to narrow down his chemical composition... but it's slow going."

"Hmph," Wally muttered. "Maybe we should try Selenium? Or melt down one of the knives to see what's in that?"

"I've tried," Okuda informed him disparately. "Whatever it is, it's almost completely inert. As far as I can tell, it only reacts to Koro-Sensei."

"That... narrows it down, I guess?" Wally scratched his head. It wasn't much, but it wasn't nothing. Maybe Nagisa'd have more?

The conversation continued as they walked. But, Wally was disturbed to discover, the topic shifted almost constantly. No matter how often he tried to lead the discussion back to how to kill their homeroom teacher, either Karma or Okuda would find something else to talk about or another student would join them.

Most common segues involved questioning into Wally's past. The usual stuff, really. Life in America, friends and family, hobbies... all things that had been pushed to the wayside for this missions and, as such, were things he emphatically did not wish to talk about at this point in time.

It didn't take the other students long to take the hint- Wally was hardly subtle in shutting down conversation pertaining to himself- and to lead the conversation in other directions. Wally tried to keep the focus on Koro-Sensei with mixed results.

When they finally reached the main campus and began to disperse along their own individual routes home, Wally watched as Nagisa separated from the girl with green hair and made to head south.

As everyone else continued to slowly depart around him, Wally waved Karma and Okuda a goodbye once he was sure they were heading west and followed after the girl with the notebook.

Nagisa couldn't say for sure what alerted him to the other's presence. If he were pressed, he'd claimed he'd felt the pursuing individual, but that didn't quite explain the particulars of it all. It was a little too instinctual for such base description.

He slowed his pace, turning his head around to peak over his shoulder and achieve visual confirmation of West's approach. Upon this, he stopped and waited for the foreigner to catch up.

"Hey," West greeted with a cheerful grin and jaunty wave as he neared. He was far livelier than he'd appeared in class. But, Nagisa supposed, Koro-Sensei tended to have that effect on new people. And old people. On all people really.

"Hello," Nagisa raised a hand to return the taller boy's greeting, though at a far more subdued pace. "What are you doing here?"

"I'm on my way home," West shrugged, gesturing vaguely in the direction they had both been walking just a moment ago. "My place isn't far from here. Shiota, right?"

"You can call me 'Nagisa', West-kun," the pigtailed boy replied easily. "Everyone does."

"Only if you call me 'Wally'," the redhead grinned back. So far Karma and Koro-Sensei were the only ones to adhere to his request. "Where I come from, hearing 'West' is usually a sign my ass is about to get beat."

"I wouldn't worry about that around here," Nagisa assured him. "You missed it this morning, but Karasuma-Sensei usually teaches self-defense and assassination techniques during P.E.. People don't beat up on E-Class so much anymore."

"Really?" Wally asked as though he hadn't already known that. He'd been careful to dawdle as much as possible after his briefing this morning to ensure that he missed the lesson entirely. Karasuma would be able to tell at a glance if he held back. "I'll have to check that out... P.E. might actually be fun here."

"Hmm," Nagisa nodded, still standing stock still. He was a little unsure of where to go from here.

Fortunately, or unfortunately depending on how you looked at it, Wally had some idea.

"So," he started slowly. "Since you're the one with the ninja assassin training, maybe I should stick with you on the way home? I sort of made a couple of enemies my last day in D-Class that I think might be following me."

"Really?" Nagisa pursed his lips, uncertain. He certainly couldn't detect any other presences, and it was doubtful that someone from D-Class would have the requisite concealment skills.

Even so, he wasn't about to leave a classmate to fear for his life.

"I guess," he allowed, smiling hesitantly back when Wally beamed at him.

"That's mighty kind of you," Wally bowed his head a little with a grin. "Pretty girl like you, taking time out for the new kid. I really appreciate this and did I say something wrong?"

Nagisa's hesitant smile had changed to a frown in the space of a single sentence.

"Karma told you I was a girl, didn't he?" Nagisa's voice was tight and controlled. His frown clear, but tempered. Almost tired, really.

Wally paused, unsure as he awkwardly cocked his head. "Was he... not supposed to?"

Nagisa sighed, his whole body deflating for the briefest of moments before he inhaled deeply, closing his eyes as he calmed himself. It was just Karma playing a stupid joke. He wasn't about to upset himself over something so trivial.

"No, he was not," he said, as plainly as he could. "He was lying to you. I'm a guy."

Wally blinked. "...really?"

With a soft sigh, Nagisa confirmed it. "Really."

"Wow..." Wally took a small step back. "This is... awkward."

There was a pause as both boys stared at each other, neither one really sure of how to proceed.

"I am so sorry," Wally eventually told him.

"It's... fine," Nagisa tried to wave it off. "Really. Karma does this kind of thing a lot."

"Well, then remind me to kick his ass tomorrow," Wally promised.

Nagisa smirked. "I think you'll find killing Koro-Sensei a simpler goal."

"Yeah..." Wally saw his chance and took it. He needed to change the conversation. "Speaking of... Karma mentioned you've been keeping track of his weaknesses... he actually said I'd probably have to date you to get a look at them, but now I'm thinking that was just so I'd play along with his joke..."

Nagisa gave off a quiet snort, "Yeah. That sounds like Karma."

Reaching into his satchel, Nagisa pulled out the notebook Wally had seen him working on in class. Small and unspectacular, one would never guess that it could well hold the secret to saving the world.

"You can have a look if you want though," he offered. "And you won't even have to buy me dinner."

"Really?" Wally's eyebrows shot up in surprise. The value of this thing was almost incalculable and he was just giving it away?

"Sure," Nagisa shrugged. "It's not much, I know, but at least this way you'll be caught up with the rest of us."

Wally flipped the cover, finding that the first few pages were scribbled with doodles and measurements of Koro-Sensei. The actual weaknesses didn't appear until the fourth page and so far took up less than half a page in and of itself.

He scanned them quickly, noting that one of them was an observation Superman had already passed on to him. Koro-Sensei, despite his incredible speed, landed incredibly weak punches. He wasn't anywhere near as solid as he looked and the strength of his attacks reflected that.

A few others were odd... when he tries to act cool, his weaknesses show? He is humble and subservient to his superiors? He can't sleep on a pillow other than his own? Was he reading these right? Did these even count as weaknesses?

And then there were a few others that were a little perplexing. Koro-Sensei is surprisingly quick to panic. He has no patience for wire puzzles.

That... could be very interesting.

And then there was this.

"Koro-Sensei Weakness #4," Wally read aloud. "'Boobs'?"

Nagisa actually blushed, careful to avoid Wally's eye. "He... isn't exactly subtle about his tastes. And he keeps a collection of magazines in his desk."

"But boobs are a weakness, now?" Wally inquired. If they were, then maybe he did have a Kryptonite of his own to worry about.

"Yes," Nagisa agreed firmly. "You should've seen him when he met Bitch-Sensei. He loses all focus."

"Huh," Wally briefly wondered if he could convince Wonder Woman to flash Koro-Sensei 'for the fate of the world'. If he could prove to Batman that it would be effective, maybe dreams could come true...

He frowned.

"Wait, who's a bitch?"
