A/N: Alright! We are at the first episode. Some of the words are directly from the manga and some are just similar. I don't know how closely I'm going to follow the story line throughout the fic but we'll see. Also thank you for the follows. Please leave a review if you like the chapters and such so that I know whether I need to mix things up or not:) Okay, enjoy!


Timeskip (First episode)

Slithery sounds of something slimy crawling across the floor could be heard outside the wooden doors of Class 3-E. The students all had their heads down, a heavy atmosphere clung to the room much like the humidity. Outside, the slithery sounds stop as the door slides open to reveal a large yellow octopus in a teacher's robe.

"We will start homeroom now!" He greeted, "whoever is on day duty, issue your commands."

Nagisa called out, "Stand!"

The whole class stood as one unit—minus one student—guns aimed at the front of the room. There was a tense beat before Shiota-san issued his next command.

"Attention!"

Another beat of silence.

"Now!"

The whole class openly fired at their teacher. Immediately the octopus started dodging the bullets, moving side to side so fast he left an image clone of himself so it appeared like there were three of him. The bullets he couldn't dodge were being knocked to the side with the pen in his hand.

"Alright, seeing as you are all still firing, I will take attendance. Isogai-kun," he called out to the mass of student assassins.

"Hai" came a wavering voice.

"I'm sorry, but as we are in the midst of gunfire, could you speak up?"

"Hai!" Isogai's voice rang loud and clear this time.

"Okajima-kun"

"Hai!" Pervert dude.

"Okano-kun"

"Hai" That one girl who's kinda athletic I think?

"Okuda-kun"

"Hai!" Ah, the quiet science girl.

"Kataoka-kun"

"Hai" Ummmm… whoops. Still don't know who she is.

The list continued through the whole class. Mizuki attempted to remember the names and faces of her classmates, but she was more focused with her task.

The list finally got down to the last few names.

"Yada-kun"

"Hai!"

"Yoshida-kun"

"Hai!"

"Hiyashi-kun"

At the sound of her name, Mizuki threw open the window to the classroom from the outside and aimed her gun at her unexpecting teacher. Except, instead of seeing the side of his giant yellow head, all she saw were his white beady eyes boring right into her own.

Realizing she had already lost the element of surprise, Mizuki stopped firing and was soon followed by the rest of the class. Sighing, she stepped over the ledge of the window into the classroom before taking her seat at the back of the room.

"No absences! How wonderful! Sensei is very pleased." The aggravating yellow monstrosity exclaimed.

As they collected the ammo for their guns, their senses lectured them on their tactic.

"What a shame. There were no direct hits today either. Tactics which rely on only numbers lack individual thought." He said with his ever present grin, "Your gaze, the direction of your guns, the movement of your fingers. Each and everyone is far too simplistic."

The whole class looked down in shame and defeat. How could they kill someone who could dodge so many gunshots at once?

"Hiyashi-kun, that was an interesting tactic. It was a good idea to attack from the side; however, I could smell your scent from that direction."

Teresaka-baka yelled from the back of the room, "Teme, what do you mean you could smell her? You don't even have a nose!"

Face flashing purple with an X for a brief second, the octopus replied, "Actually, I have two nostrils that I keep hidden under my eyes. My sense of smell is really quite strong."

"Hey! Are you sure you dodged all of these? I mean they're just BB bullets. You could've just pretended not to get hurt." Maehara accused from the front of the room. The whole class perked up at that, joining him in question their Sensei.

"Someone hand me a loaded gun, please." The octopus said with a bit of a sigh, holding out one tentacle towards the class.

One of the girls at the front of the room held out her handgun. Grabbing it from her, their sensei aimed it at one of his other tentacles and pulled the trigger.

BAM!

The end of his tentacle was blown off and wriggling on the floor. Ok ew that's kinda gross.

"I told you already, these bullets were specially designed by the government in order to kill me. They are able to slice through my cells like tofu. Of course my cells will regenerate after a few seconds. To you they are regular BB pellets. That said, it can still hurt you if it hits your eyes, so no firing during class unless you want to kill me."

"Haaaaiiiii" the class drones out, dejected at their failure.

"Nruhuhuhuhu! I hope you can all kill me before your graduation." He teased, his arrogance shown by the green stripes on his face.

Ding-dong

The bell signaling the start of the school day chimed as the strange sensei ordered his students to clean up.

The day wore on without incident. Mizuki sat in the back with her latest book hidden in her lap. She had recently gotten into body language and was hoping it would help her social skills when she inevitably lost her whole "mute" persona.

So far, it has been quite helpful, but she knew that they were not convinced. Ryonosuke-San was kind but he needed to stop trying to get her to talk. He had attempted to make conversation with her every single day and failed each time. She wasn't sure why he wouldn't just buy her story like everyone else but it was starting to get on her nerves.

The other person was actually her sensei. A few days after he first came, he had asked her to stay after class and confronted her about it.

Flashback

"Hiyashi-kun, could you stay back after class please?"

Immediately the class perked up a bit. The ex-class A elites already in trouble with the alien teacher? Mizuki could practically feel the stares of her fellow classmates. Nevertheless, she nodded her head at the teacher in acknowledgment.

After class, she put away her notes and books before pulling out her phone to message her siblings that she would be late to pick them up.

Once everyone had left, she picked up her bag and walked to the front of the room where her sensei was finishing up erasing the notes from the chalkboard.

"Why do you pretend to be mute?"

His sudden outing of her lie threw her off. Still she refused to speak. She tapped on his desk to get his attention, but he would not turn around.

" Hiyashi-kun, I have ready your student profile and there is no where that indicates any reason for you to be mute. I will not face you until you give me the courtesy of a response."

His mistake, she thought slyly pulling out her anit-sensei knife from beneath her sleeve. Holding it in her hand, she stabbed him from behind the teacher podium between them. Instead of meeting yellow flesh, however, all she found was a white chalk in her hand instead of the anti-sensei knife.

Glancing around, she spotted her sensei staring at her from the corner of the room holding the anti-sensei knife with a cloth. She narrowed her eyes. This was a test of wills and she would not be the first to back down. Going to the board, she wrote out, "I don't know what you mean sensei. The accident may not have been in my records but that doesn't mean it didn't happen."

"Hmmmm," he hummed thoughtfully, "Well then, I suppose there is nothing I can do about it. You may go."

Picking up her bag, Mizuki rushed towards the door but not before her sensei called out, "It won't work you know."

She knew she should just leave. Unfortunately, curiosity got the better of her and she turned towards him with an inquisitive glance.

"No matter how hard you try to distance yourself from others, there will always be at least one person who manages to weasel their way into your heart. It is then you'll realize how much joy others can bring into your life. Don't wait too long to let them in Mizuki or you'll end up regretting it." He said, staring out the window with what almost seemed like a longing glance (but it was impossible to tell because his face always looked the freaking same).

His speech made her uncomfortable. Uncomfortable because she felt at that moment she wanted to pull down her walls and let her classmates in. Instead, she rushed out, breaking the spell, bringing herself back to reality.

If there was anything she did gain from that conversation was that her sensei was almost definitely human before he became whatever he was now. He claimed to have been born and raised on Earth and seemed to have first hand knowledge on human emotions. No amount of studying could allow one to understand human emotion to that extent. Humans were simply too complex.

As she walked to pick up her siblings from their school, she decided to keep that in mind and to forget the real piece of advice her sensei had hoped she would take away from their talk.

End Flashback

Mizuki rapidly blinked realizing she had blanked out and was reading the same line over and over again. Sighing mentally, she closed her book and slipped it back into her bag next to her desk. She couldn't seem to focus today. None of the strategies she could think of were going to kill the stupid octopus. How in the world were they supposed to kill someone who could move at Mach 20 and seemed to know their every move? They couldn't even sneak up on him.

She glared at him standing at the front of the room calmly teaching the class about the relative terms… Hold on. I thought these guys were further behind than this. Wow, I must have been spaced out longer than I thought. I mean, this is Class E; they're supposed to be slower at learning.

Bam!

A gunshot was heard coming from the middle of the class. The class stared in resigned exasperation at their teacher as he held the pink bb bullet between two pieces of chalk like chopsticks. At this point they were not surprised the shot didn't hit. Mizuki looked towards her right to see who had attempted the attack. Standing at her seat was that white, blond haired girl whose name she could never remember. All Mizuki knew was that the girl was a goofball and had a loud personality.

"Nakamura-san!" Their sensei scolded, "I told you that your assassinations cannot interfere with your learning. Go stand in the back of the room for the rest of the lecture as a punishment."

Nakamura put a hand behind her head in embarrassment, "Hai, hai, sensei. No need to turn red like that when you're angry."

Putting her gun down at her desk, Nakamura walked to the back of the classroom and stood behind the desk next to Mizuki. She leaned against the classroom's back wall looking like she didn't have a care in the world.

Mizuki, on the other hand, was irritated. Nakamura could have stood anywhere else in the back of the room and she had to go choose the spot right behind her. Personally, Mizuki thought Nakamura would have fit better behind Teresaka, aka Idiot. The class goofster and class idiot would go great together. But it seemed Nakamura wasn't interested. Instead, she seemed determined to peek over Mizuki's shoulder to see what she was working on.

Annoyed at the lack of privacy, she flipped to a new page on her notebook and wrote down, "Do you mind?" before lifting the notebook slightly to allow the annoyance behind her to read it.

"Hmmmm, that depends. What were you writing in there Mizuki-chan?" Nakamura whispered in a playful voice not at all deterred by the rude message.

Mizuki huffed silently before writing another note, "I am writing notes for the class, obviously. Also I would appreciate it if you refrained from such a familiar title. We are merely classmates."

She could feel Nakamura's smirk as she said, "Those didn't look like English notes, Mizuki-chan."

"Well, then I guess the rest is none of your business." Mizuki wrote back deciding to ignore the girl behind her from then on. All she wanted to do was go back to her list of ways to kill their sensei which was aggravatingly small due to his far too many advantages. She didn't want to do it with her classmate peering over her shoulder the whole time, though. It wasn't just privacy. Mizuki needed that prize money to ensure her siblings' future as well as their escape from their horror of a father.

"That's no way to speak to a classmate who is worried about your education. After all, you probably need to pay attention if you ended up here in Class E with the rest of us." Nakamura's voice lost a bit of inflection towards the end as she recalled her own failures that led her to the End Class.

Mizuki was done. All she wanted was some peace and quiet with her thoughts and schemes. Besides, she already knew the concept they were learning as English was her best subject and being booted to Class E had nothing to do with grades for her. Irritated with her classmate, she wrote, "Please. Unlike you, my presence here has nothing to do with my inability to grasp the lessons. Instead of being hypocritical, why don't you focus on what sensei is saying before you fall behind? Oh wait, there is no where left for you to fall."

After reading the scathing message, Nakamura fell silent. Whether it was due to anger or shock or some other emotion, Mizuki couldn't find it in herself to care and decided to rest her head on the desk as she stared at the front of the room while drifting off into her mindscape.

POV Change (Nakamura Rio)

Rio didn't know whether to feel outraged or sad. On one hand, this Hiyashi Mizuki had no right to be talking down to her in such a way. What did she know? She was just a stuck up elite from the A Class who couldn't accept her fate as one of the scums of Kunugigaoka Junior High. On the other hand, there was some truth in her words. While Rio had no trouble keeping up with what her sensei was teaching, she had lost her motivation to learn.

Being an outcast at such a young age takes a toll on one's psyche. Especially if that child is an extrovert that thrives on her connections and friendships with others as Rio does. Now, she had gotten the friends she so desired but lost her genius title in the process and was stuck in the End Class.

Rio shook her head to clear it before the depressing thoughts got her down. She was known as the cheerful class clown. She couldn't let herself get down. Instead, she decided to settle on her anger at her stuck up classmate. All she was trying to do was goad the girl into opening up a little but instead she somehow ended up closing up more while offending Rio and all their classmates in the process.

You know what? I don't care. She thought, still miffed at the other girl's words. Clearly she still feels superior to the rest of us. Just wait a few weeks and she'll realize she is just as doomed as the rest of us.

Back to Mizuki POV

After telling off the blonde behind her, Mizuki fell into a sleep-like daze. It was a habit for her especially when she grew bored or someone was prattling on about a topic she could really care less about.

Ding Ding Ding

The sound of the bell signaling the end of class broke her out of her trance. She glanced up at the front of the room just as her sensei was raising a slimy yellow tentacle at them saying he was going to China for their famous Ma Pao Tofu.

*sigh* Mom made the best Ma Pao Tofu. Mizuki thought with longing at her late mother before shaking her head. Nope. Not dealing with this now.

Instead, she glanced around the room at her classmates. So far, she had deduced that she would not be able to kill their sensei on her own. As much as it hurt her pride, she knew this was something she could not do on her own. Now the question was how she could use her classmates' strengths to corner her sensei.

Mizuki glanced around the room, trying to determine who to approach first. If they were going to help her, she would have to make friends with them. Probably shouldn't have been so rude to Nakamura-san then. A small voice in the back of her head whispered.

Truth be told, she felt slightly guilty, but really the other girl should mind her own business. Besides she was technically only stating facts even if the wording wasn't the gentlest. Class E students truly had nowhere left to fall. Except being expelled like you almost were…

Mizuki's face screwed up in irritation. Her inner voice was annoying today. She was about to stand up to stretch her legs when she noticed the dummy and his crew move towards her side of the room. She tensed for a second ready for a confrontation, but they simply passed her and headed towards Shiota Nagisa's desk.

The poor blue haired boy looked even more feminene than half the girls in the class. She wasn't sure why, but she had a feeling it wasn't his choice. Something in his eyes gave her the sense that he was constantly miserable in a way that didn't have anything to do with the fact that he was in Class E.

Mizuki narrowed her eyes as the three boys cornered the smaller boy at his desk before they all stood up and headed out the door. Mizuki was pretty sure that Shiota was being bullied into going with them but it also wasn't her business so she wasn't about to interfere.

Imagine if that happened to Reo and someone watching used the same logic as you…

She scowled as the guilt built in her gut. No, she wasn't about to give into her inner voice. Nothing ever good came of her risking herself for someone else. So, she simply stood and stretched her hands over her head letting out some of the aches of sitting for so long. When she opened her eyes and put down her hands, she could see Kayano Kaede, Nakamura, Maehara Hiroto, Okano Hinata, and Isogai Yuuma whispering amongst themselves while stealing glances at her.

As their conversation wore on, the glances started turning into glares. It wasn't difficult to figure out. Nakamura probably was telling them about what she said and they were defending their friend by hating her. I can use this. Mizuki thought. It was the perfect time to catch them off guard by a kind gesture.

If I apologize then they will doubt their own judgements and feel guilty for jumping to conclusions about me. This will make them more receptive to my plans for killing in the future.

Writing a quick, genuine sounding apology on a piece of paper Mizuki approached the gossiping group.

"What do you want Hiyashi?" Nakumara questioned sharply, not wanting to deal with another insult.

Holding out the note, she let her read it.

Nakamura was quiet for a bit, eyes scanning the note again and again as if trying to find the lie. When she didn't detect one, she looked back up at the brown haired girl, "Tch, it's fine I guess. It's not like you were completely wrong."

That statement took Mizuki off guard. Her surprise must have shown on her face because Maehara spoke up next, "Yeah that was rude, but it's true that we don't have any lower to fall."

The whole group's atmosphere dampened heavily at that. It was a common occurance any time someone mentioned the future of those in Class E. After all, who wouldn't feel discouraged when everyone kept telling them they were stupid scum not worth the time or attention?

Deciding to break the gloomy atmosphere, Okano spoke up, "It's alright. If we manage to kill sensei then we'll be set for life with ten billion yen." The conversation gained ground quickly after that.

"Yeah, we would never have to work with that much money." Nakamura started with a smirk thinking of the enormous prize money.

"But we have to actually kill him," Maehara countered, "if not then… well, the money won't matter I guess because we'll all be dead."

Isogai laughed, giving his friend a friendly shove, "Don't be so pessimistic, Hiroto. We'll find a way before March."

"You know, I think Nagisa-kun has been taking notes on sensei. He might have some helpful tips about how to gain an advantage to kill sensei." Kayano added.

Bingo. Mizuki thought. I guess other people can be okay sometimes.

Now that she had the information she needed, Mizuki was trying to figure out a way to excuse herself without seeming too obvious when the perfect opportunity presented itself in the form of Ryunosuke Chiba.

"Hi Mizuki-san." He greeted politely.

Waving a courteous goodbye to the rest, she walked back to her desk with Ryunosuke in tow. Grabbing her pen and paper, she wrote back, "Hello Ryunosuke-san."

"I see you are still sticking to your mute lie." he said with a bit of bitterness in his voice.

Narrowing her eyes at him, she wrote, "I don't know what you are talking about."

Scoffing, he simply replied, "Sure. ANyway, I didn't want to talk about this again. I just wanted to ask how your day is going."

Mizuki paused before writing back a single word, "Why?"

Ryunosuke sighed, "Geez, I don't remember you being so suspicious. I'm asking because that's what friends do."

"We aren't friends"

"So you say, but that isn't how I see it. Besides, you still owe me that favor remember?" He said with a small smirk.

Mizuki grit her teeth slightly. No, she had not forgotten but she had hoped he had. "What do you want?"

"I want you to admit we are friends and come hangout with me after school tomorrow like a friend would."

Mizuki was still for a second trying to think a way out of this. Her whole purpose of acting mute was so this wouldn't happen. She didn't want these bonds of friendship. They meant nothing because in the end everyone just betrays you for their own selfish purposes. The only people she would ever trust are her siblings because they were her whole world.

Aha. My siblings are coming through for me even now. She thought as she wrote out her response.

"I can't. I have to pick up my siblings after school everyday." She wrote out smugly thinking he would have to come up with another favor.

"Okay, that's fine. I'll go with you to pick them up and we can go for ice cream afterwards." He replied easily before going back to his seat so she couldn't argue.

Wha- That little… Ugh. Fine. I do still have to pay up. Better this than something worse. Mizuki relented in her mind. Guess I have a date tomorrow afternoon.
