"Well. This is awkward."

If anything, Nakamura's joking comment only intensified the tension between the two classes. The classroom was somehow bigger than it was before, with twenty extra seats at what used to be the back of the classroom but was expanded over the weekend.

Uraraka poked Iida, whose arms were quivering on his desk. "You're our class rep, right? Say something, maybe? Anything to break this tension?"

Iida swallowed and took the girl's advice, shooting up from his desk and walking to the front of the classroom. A few students squeaked in surprise at the shrill screech the wooden chair made as it scooted backwards. Iida cleared his throat and whipped out a set of cue cards. "Good morning, class 3-E! I'm the class representative of UA High's class 1-A, and I would like to declare that we will try our best to learn and cooperate with you to save the planet from this villain's wrath -"

A gust of wind almost knocked him over as the blur cleared up to reveal Korosensei. "Excuse me for interrupting, Iida Tenya-kun, but starting today, you are students in my classroom. Therefore, I would prefer that you call me by the name my class has bestowed upon me: Korosensei."

Bakugou clicked his tongue in annoyance. What makes him think he's in a position to demand something from us? We're the ones killing him here, aren't we? He flipped the green knife distributed to the class last Friday over, staring unblinkingly at Korosensei. How fast is he, anyway? The ash blond thought, taking aim and letting the knife sail through the air.

"... since I still don't know your class very well, I was hoping that you, as the class rep, could -" Without a single trace of shock on his face, Korosensei paused mid-sentence and caught Bakugou's knife with a handkerchief in his tentacle. "Not yet, Bakugou Katsuki-kun. I would like you to start your assassination attempts only after I've properly introduced myself."

Bakugou crossed his arms. "Was just testing the waters, teach." So he really is fast...

"On behalf of my students, I would like to extend a warm welcome to the heroes-in-training of UA's class 1-A. As I have just mentioned, do call me Korosensei, now that I have taken you under my wing for the time being. Well, under my tentacles."

Someone sneezed.

"Sorry," Hagakure apologized as Ojiro handed her a tissue.

"Anyway, A-class, I hope you won't think that having quirks makes you more worthy of taking my life than E class, because in my classroom, quirks don't matter. You can use them as an accomplice to success, but you can't simply rely on them. As for 3-E, think past the fact that they have quirks while you don't. We're all equals here in this classroom, and it will please no one if your differences in genetics drive a wedge between you."

"Are you done?" Terasaka grunted, irritated.

"Nurufufufu, I see you're very impatient today, Terasaka-kun. Without further ado, then, let us begin roll call! Take your pistols and rifles, children, and make your responses nice and loud!"

3-E was in position already; 1-A, new to this new routine, scrambled to follow suit. "Aizawa-sensei didn't tell us how guns worked in class, did he?" Momo eyed her rifle, unsure.

"Here, do this!" Ritsu, who was wearing a bandanna with the words 'welcome to our assassination classroom', raised a virtual rifle of her own in addition to the actual guns that emerged from the sides of her box.

"Thank you," Momo said gratefully after a simple tutorial from the AI. "And, um, if you don't mind me asking, are you -"

Ritsu winked. "I'm Ritsu - short for 'Jiritsu Shikou Kotei Houdai': Autonomously Intelligent Fixed Artillery."

"An AI! So cool!" Kaminari gushed. "And she's cute too!"

Ritsu blushed. "Thank you!"

"Can we just fucking start this off already?!" Bakugou snapped, his finger tapping the trigger of his pistol impatiently.

"Why do you always act like you're a girl on her period?" Todoroki deadpanned.

Bakugou gaped at the nonchalant boy. "The fuck, Icy Hot?"

Uraraka burst into a fit of giggles. "T-Todoroki-kun, you really shouldn't s-say stuff like this with such a straight f-face!"

"... I shouldn't?" That only made her laugh harder.

"Uraraka-kun, roll call is about to start! Please calm down as soon as possible!" Iida reprimanded sternly.

"Pfft! S-sorry!"

Whoa, Midoriya thought as bullets whizzed towards their new teacher from every corner of the classroom. The octopus was a blur as he dodged them at mach speed all the while reading out names from his list. "Oh, it appears that Karma-kun is absent today. All right then. Isogai-kun!"

"Present!" The class rep yelled, rejoining the shooting fest after an expeditious reloading of his weapon.

"Okajima-kun!"

"Here!"

It was soon confirmed that apart from Karma, the rest of 3-E was present.

"Now, on to our guests from class 1-A! Aoyama Yuuga-kun!"

"Ici "

"Bonjour, Monsieur Aoyama! Ashido Mina-san?"

"Heeeeeeere~!!" came Mina's overenthusiastic shout.

"Energetic! Asui Tsuyu-san?"

And so roll call went on like this until at last Momo had her attendance taken (with Bakugou screaming 'DIE!' at Korosensei when his name was called, leading to Kirishima, Kaminari, Mina and Sero having to stop firing at Korosensei due to an outburst of laughter as the teacher reacted to Bakugou's statement with an 'I wish you the best of luck!') A collective sigh rose from E-class as they lamented yet another failure at killing their teacher, while A-class buzzed with comments at the back.

"How the heck did none of those bullets manage to hit him?!" Mineta screeched.

"This is the perfect wake-up call! I'm fully awake now!" Kirishima grinned.

"Same!!" Mina pumped her fists in the air.

Midoriya immediately grabbed his notebook and began scribbling furiously in it. "... he's fast... unknown quirk... do the tentacles play a role in his speed...? Aizawa-sensei said something about him being able to move as fast as Mach 20... some kind of mutation, maybe?"

"There he goes again," Ojiro sweatdropped.
