"Nurufufufu~"

The octopus' black, beady eyes peered down at you, along with the rest of the students in 3-E. As comical as he seemed, with his protuberant head, silly smile, and signature laugh, the authorities sternly elucidated the caliber of such a monster. A year from present-day, on March 13th, the monster would destroy the Earth, if not properly dealt with.

Tadaomi Karasuma, an agent sent from the Ministry of Defense, was to serve as an assistant teacher to supervise the tentacle-sporting beast. His blankly serious expression contrasted the yellow octopus' goofy one, though he seemed cool nonetheless.

The same creature that had obliterated seventy percent of the moon into antimatter stood before you, his slimy tentacles waving around at Mach 20 speed as he plastered calligraphy on the empty walls at the back of the classroom.

'Tentacle', they read. In spite of the dire situation, you discerned a small coterie of delinquent boys poking fun and whispering inappropriate jokes in the background.

Ignoring them, you avert your gaze around the other parts of the degenerating room, as the decaying wood clearly displayed the way Kunugigaoka's funding was distributed-- anywhere but the End Class. Rather, the sole explanation for allowing an octopus to teach class was for the sake of more funds for the elite-- a ten billion yen bounty shared between those involved in the homicide.

Arrays of windows lined the sides of the classroom, allowing warm light to filter in on sunny days, and fresh air in general. The seats were mostly filled with your new peers, roughly twenty-five others in the locality, stuck in the same state as you.

You lightly sigh at the circumstances given, a train of thought chugging interminably to solve your dilemma. Class E was to become the Assassination Classroom, a place kept secret from the rest of the school, in terms of massacring a colossus.

You were afraid of dying, uncertain of utilizing a weapon. You thought that there was no way mere students could have the capabilities to assassinate such an omnipotent being-- one that not even the world's most talented assassins could handle, despite the administration's rational reasoning to prove otherwise.

On the bright side, the monetary reward acted as a tempting sweetener, and for just a split second, you greedily fantasized about all the favorite things you could've purchased with the bounty, guilty as charged.

Well, it wasn't like you had a choice, anyway.

Loaded with anti-sensei BBs, an assortment of guns, firearms, pistols, revolvers, rifles, and others were handed out to the class accordingly. You gripped onto the gun's handle with both hands tightly, palms growing sweaty from agitation-- it was your first attempt, after all.

Was your aim going to be successful? Probably not. Was the octopus going to be killed? Refer to the previous query.

Promptly, a bombardment of BBs shot towards the homeroom teacher, pellets ricocheting off the wooden walls, and bouncing flat onto the floor. Seemingly without effort, the yellow tentacles sped around in Mach 20 speed, and in less than a second, all weapons were temporarily confiscated from the students, yourself included.

Your eyes dilated at the sight, of not having the weapon in your hands any longer. The other teenagers had felt the same, gasps of surprise, shock, fear, and admiration filling the room.

"Nurufufufu~ Your mobility and assassination skills need work, students, though it wasn't too shabby for your first try. Not to fear! Karasuma-sensei will be your Physical Education teacher, and I'm sure he'll be able to shape you into perfect assassins!" the octopus smiled, green stripes suddenly embellishing his face.

An exasperated sigh escaped the supervising adult, rolling his eyes as he proceeded to observe stoically.

"Now, class, let's proceed on to self-introductions!" Even if he was a monster, he was oddly motivated and passionate about the role of teaching, grasping onto several pens as he prepared to write in his notebook, adorned by a crescent moon motif.

---

You were obediently listening to the other introductions, finding your classmates for the year rather interesting. You had almost forgotten that you were even in the End Class, from the lively events that transpired on the first day. Was this really the 5% of Kunugigaoka used as scapegoats? The 5% that was hated?

"I'll certainly expect for you to climb the ranks by the end of this year. Okay?"

Your mother's words repeated, snapping you back into the reality that 3-E was not a place intended for fun and games. Alongside the assassination business, you had to boost your marks, to be on par with the top 95% of the populace.

"Try befriending others while you're there, alright?"

Paying heed to whomever was speaking, the activity progressed relatively quickly. In particular, Nagisa Shiota and Kaede Kayano were specific individuals that you found especially intriguing, having the desire to hopefully befriend them.

You recognized Kaede as the girl who spoke about naming the instructor Koro-sensei during her introduction, derived from the word 'unkillable' (korosenai), which was indeed, quite clever.

On the topic of friendships, however, you couldn't help but to wonder how Kaho was doing, back in C Class. Was she okay without you? Were you okay without her?

"Last but not least, [Name]! Please, make your way to the front of the class for your highly anticipated speech~! Nurufufufu~"

Your muses were interrupted by Koro-sensei's announcement, blinking widely at the sight. You hadn't even realized that you were the last one to go up. Awkwardly, you stood up from your seat, pushing out your chair, as you stepped towards the center of the classroom in your school uniform, your [length] hair in its usual style, and [color] eyes suddenly firing with determination.

"My name is [Name] [Last Name]. It's a pleasure to meet you all! Ah... my hobbies include [activities], and I like [stuff]."

The rest of the students applauded, as you politely bowed. You were sauntering back to your assigned desk, head held mellowly low, only to suddenly halt in your tracks as you bumped into human flesh.

You glance upwards, only to see that you had made it to the doorway. Standing beside you was a slender teenage boy in a black blazer (a rebellious choice, opposed to the standard uniform), pale skin, and sharp, golden mercury eyes. His unmistakably short red hair was the explanation for your stupefaction.

Karma Akabane, the vicious bad-boy threatening to all.

You didn't understand-- his grades were said to be excellent, so there was no plausible reason for him to be in E Class for poor performance. Regardless, you were caught up in the moment to think properly, quickly voicing your apologies.

"I'm terribly sorry--!"

Karma glanced over at you, his vehement eyes almost softening as his lips tugged upwards into an amused grin. "Mm~? Don't think too much of it. [Name]-san, was it?"

At that instant, the revelation became pellucid.

With perfect timing, he arrived during your lovely introduction. He was aware of your name.
