Well, I'm back! And this is the final Class 3-E character to be added to the mix! WOOOOOOOO! Man, it has been such a long time since I first uploaded this fic and everything and now it's coming to an end. There's still one final chapter and a few mini omakes, but all in all, this fic will be ending soon.

Is anyone looking forward to Terasaka teaching the class? You know, half the stuff in this chapter is stuff I made up when I write and the rest is loosely based on the plot I have in my head for the past two years. Yea, I'm a really consistent writer. Obnoxious, but consistent. Now can anyone tell me where that quote came from?

Anyways, it is best to just stop my Author's Note and let you all read. So, please sit back (or lie down on your bed if you are doing that), relax and enjoy!

When Nagisa signed up to be a part time assassin, he did not expect his job to take up so much time of his teaching career. He really loved the students of Class 3-5, every single one of them, and he felt that he is not spending enough time with them to improve the bonds between teacher and student.

He really wanted to turn down the latest assignment given to him by his ex-mentor. It was really tempting to but...

He glanced at the downloaded PDF document in his files.

He turned his attention back to his phone with his messaging application available right on the screen and Karasuma's name glaring at him.

Moving his mouse, he directed the cursor to click on the downloaded document and skimmed through the assignment.

Then he read it again.

And again.

And again.

Five minutes later, he sent off a message to his ex-teacher.

To: Karasuma Tadaomi

Time: 10:43 p.m.

I'll do it, provided that I get a two-month break. No assignments during those two months.

It was the same boring old day for one Terasaka Ryoma. He wakes up, does his daily morning routine and goes to work just to get yelled by his boss. How is it that even politicians have bosses anyways?

Back to point, Terasaka was having his usual grumpy day. He mouthed off some random intern in the IT department and cursed his boss behind his back, He grumbled at the fact that he did not stock up his kitchen the previous day and thus has to go out grocery shopping after work that day. He complained about the non-existing workload he had. Its like his day couldn't get any worse.

Then his phone rang.

He jumped up at the sudden ringtone and started frantically searching for his phone. Where the hell was his phone, did he not leave it on the table five minutes ago? From the corner of his eye, he saw his boss seating up and giving him the "look", which basically meant that if he did not shut the phone up in five seconds something bad will happen. Without even looking at the Caller's ID, he accepted the call and placed the phone next to his ear as he got up from his seat and exited the office, failing to notice the stink eye his boss was shooting at him as he did so.

"Terasaka speaking. What the hell do you want?"

There was a familiar laughter from the other line. "Terasaka-kun, you are as brash as ever."

"Oh, yo, Nagisa. What's up?"

There was a slight cough that could be heard from the other line. "I'm hoping you can do me a favor actually."

Terasaka snorted. "What, with that shitload class of yours?"

Spluttering could be heard. "W-What did you just call my students?"

"Dunno. Seems like a pretty accurate description if you ask me. Everything I've heard about them from the WhatsApp group gave me a headache," the dirty blonde haired man said as he idly kicked the wall beside him, leaving shoe-prints on the pristine white walls of the building.

"A WhatsApp group? And where am I in this group?"

"Hmph. Dunno. I don't think Okajima bothered to add you into the group."

"... I need to have a word with him."

"Yea, so I gotta be you for a day at your class, huh?"

"That's the idea, provided that you can do it?"

"Argh, sure. I don't have much to do anyways."

"Thank you, Terasaka. I hope you have a nice day."

"Yeah, you too," Terasaka grumbled as he hung up. He pocketed his phone and entered his office, taking his seat.

"Hey, bossman!" He yelled, even though the man was already sitting in the same room. "I'm busy tomorrow and can't make it to work!"

He ended up staying back after hours to finish the next day's workload.

Nagisa sighed. He didn't want to have to resort to it, but there was no one else available for the job. He tried contacting a few other of his friends and they all were having busy work schedules. Of all people, Terasaka is definitely a person he wanted to put on his "last resort" list. Not that he does not trust the man, but Terasaka just does not have the skillset to be a substitute teacher. One must wonder how on earth the man managed to get himself to where he is now.

The teal headed man then proceeded to get his things ready for his next mission, not getting much done as he constantly found himself worrying over his students and the possibility of Terasaka just sleeping in the middle of class. Amongst all the 3-E classmates, the dirty blonde headed man was the one who changed the least over the seven years. Till this day, Nagisa is not sure whether that is a good thing or not.

Going through his checklist. For example, making sure that he had ten knives, with an extra five hidden all around his body. He added several necessities like a first aid kit, a handgun or two (He particularly likes the Colt 40) and his specialized lockpicking kit. He also stuffed a few shirts and pants into a small bag. After all, one can never know when extra clothing will come in handy, especially when one is in the profession of an assassin, or a hitman.

Once again, his mind began to wander. He really hoped that his decision to call on Terasaka for help was not something he would regret.

The state of his bedroom was in a mess.

Terasaka looked around the place, scanning for something that he could use as teaching material for Nagisa's students. Contrary to his friends' beliefs, he can take things seriously. That is, if he wanted to. Teaching should be an easier job compared to what he was doing anyways.

His eyes landed upon a large book buried under a few textbooks he still kept in a corner of his bedroom, even though seven years has passed since the last time he touched them. He couldn't really remember what the large book was about, but if its big then it should be good teaching material for kids. He grabbed the book and shoved it into his rucksack. After a few moments of hesitation, he also shoved the rest of the textbooks into the rucksack.

He then checked his mess of a bedroom once again. Sure, he would not be as awesome a teacher like Koro-sensei, but he at least wanted to be a decent one, though it is only a substitute position that he will be filling in.

It was not ten minutes before he gave a groan of frustration and gave up. He had just shoved in a few books into his bag, after all. That should be enough for the students anyways. For now, he deserved a good eight hours' worth of sleep. That boss of his really was a slave driver, making work after hours that day!

It was a beautiful day in Paradise High School. Students and teachers were bustling around, getting ready for the day in school. It was the usual day, really, with nothing out of ordinary.

That is, until a large bulky man came stumbling into the gates of the school.

"Incoming! Sorry! Substitute teacher incoming!" The man yelled as he stomped all over the place.

Everyone made way for the strange man, staring at him as he made his way through the school. Who on earth is this person and what is he doing at their school? They seriously doubted that he was a substitute teacher, as he was not even wearing the proper attire to be a teacher in the school.

So, one very responsible teacher by the name of Ishihara Kotoko decided to take matters into her own hands. Taking a step forward, the teacher made her way through the large crowd and placed herself firmly in front of the unknown person, effectively stopping him in his tracks.

"And who are you exactly, mister?" The woman asked firmly as she stared the stranger in the eyes, trying her very best to as intimidating as possible. "There has been no absent notice from our current teachers so there shouldn't be a need for substitute teachers today. Unless you make yourself clear as to who you are and what you are here for, please leave the school compounds."

The brunette scratched his head. "Name's Terasaka Ryoma, I don't know which class I'm supposed to be substituting but it's Nagisa's class."

With those words, everything went silent. Students and teachers alike stopped whispering to each other as they processed the words that were just uttered from the man's lips. Everyone knows who Shiota Nagisa is. Of course they do, that man is the homeroom teacher of the 3-5 class. Everyone has seen the teal headed man around the school multiple times but have never held a conversation with him. None of the students had the pleasure of being taught by him, as he had his hands full with teaching his own class. Most teachers pity him, really. None of them enjoyed the experience when they taught the 3-5 class. To be honest, they were gladder that he is the one teaching the class of misfits and not them.

"Right, so where is his class, anyways? Can anyone of you direct me?" The man asked, oblivious to the silence around him.

Well, it was needless to say that no one is willing to bring the substitute teacher to the class. Who in their right mind would even want to be near that hellhole of a class anyways?

"Hey, I'm sure one of you must know where the class is, right? If so, just lead me there!" Terasaka demanded, getting impatient.

All eyes rivetted to Kotoko. After all, she was the one who was brave enough to confront the man. She should be the one to direct him to one of the unruly classes in the campus. The female teacher sighed as she realized that she would be delaying the inevitable, and between gritted teeth she managed to bark out to the substitute teacher to follow her to the 3-5 class.

It was an awkward fifteen-minute walk to the desolated wing of Paradise High. Kotoko barely said a word and Terasaka only contributed to the situation by muttering random words and phrases to himself. With every step, Kotoko could only feel the growing sense of dread as they slowly approached Class 3-5 as the sounds of students' voices grew nearer and nearer.

Then the door came into sight. The sign with the words "Class 3-5" printed clearly on it can be seen hanging lopsided on the door. It then all happened in a split second. The door slid open and Terasaka suddenly pulled her aside. Her eyes widened as the man moved with surprisingly fast reflexes, catching what seemed to be a knife that was flying out of nowhere. Her body moved as gravity pushed her into Terasaka's chest with a gentle thud.

Ba dump. Ba dump.

It was so warm.

"Hey, you're okay, right?"

Then it all registered.

With a shriek, Kotoko pushed herself away, cheeks flushing red. What the hell just happened? She knew that the 3-5 students were troublemakers, but she did not know that they were throwing sharp, pointy, lethal items around their classroom! Why on earth did she even agree to escort this substitute teacher to their classroom anyways? She should have just given him directions and ran towards the opposite direction!

Nonetheless, there was a little voice that seemed to be fangirling somewhere at the back of her mind. Woah, that teacher was fast, and the way he caught the flying knife was so hot.

It took her a few minutes to realize that she was checking the man before out. Letting out a squeak of embarrassment, she backed a couple steps before running back to the main campus.

She just might have a crush on the strange substitute teacher.

As students of the 3-5 class, it was normal to fling random sharp object towards the door whenever the sound of footsteps approaches. It was a daily routine, in fact, just in case their homeroom teacher suddenly forgot that he had a class full of students that were waiting to kill him. Not a likely situation, but one can hope.

Thus, it was a bit of a shock when someone else walked into their classroom and managed to catch the deadly throw of a knife with ease, even managing to pull off a stereotypical scene from a romance movie as he pulled a random woman towards himself.

Natsuka watched, her eyes narrowed as the man strode into the class and looked around. She had received a message from her homeroom teacher about this particular substitute teacher. From what she read, even Shiota-sensei was wary about the man. "His attitude can be a bit… questionable." was what he wrote in his message and Natsuka did not like the sound of that.

"Throwing knifes, huh." The man said gruffly as he dumped an enormous bag onto the teacher's desk. "Gotta admit, your aim was great. Nagisa taught you guys well. Right, so he won't be here today. Instead, I'll be taking his place. The name's Terasaka Ryoma. Any questions?"

All noise ceased as the students stopped and stared at their substitute teacher. Most of them were already on their guard, ready for any sign of madness in his personality. Of course, they were not yet informed by their class representative about the current substitute teacher, but plenty of experience on their part contributes to their wariness to any of Shiota-sensei's friends.

"No questions? Right, then let's get started with classes. What period is it now?" The man then proceeded to look around the class for a timetable or a schedule of some sorts, missing the timetable that was stuck onto the teacher's desk because his giant rucksack was in the way. "Where the hell is the timetable?"

They stared at each other. Should they tell him? Before any one of them could open their mouths though, the teacher slumped into the chair behind him and sighed. "Well, never mind then. I'll just teach whatever is in the books."

Reaching for his rucksack, he pulled out some books and stared at them for a while, before tossing a few to a side. He opened a book and skimmed the first few pages, before closing it.

He sighed again. "Unfortunately, the books that I brought with me are not suitable to be taught to highschool students. So, unless there are extra textbooks here, let's talk Mathematics, shall we?"

The students who sat in the front row claimed that he pulled out a few textbooks for primary students and the rest were out of date textbooks from years ago. Did Terasaka not check before packing anything into his bag? Some eyed the large bag suspiciously, what else could be in that thing?

Nagisa cursed to himself as he nearly slipped up while stalking his assassination target. He was not in top shape that day, which is not a good thing. The problem was that his mind kept wandering to his students and Terasaka.

He was worried. Of course he was! Terasaka of all people was the one to be teaching his class, he should be worried.

The tealnette felt slightly guilty for doubting his friend. All of the 3-E students, Terasaka included, really went through thick and thin together. They were once considered scum of the school, but they managed to graduate and obtain better opportunities in life. After all that they've been through, Nagisa should not have doubted his friend.

Trust Terasaka a bit more, Nagisa chided to himself. He may not be a very reliable person in the past, but he could have changed!

With those words, the tealnette continued through his mission, certain that his friend would be able to handle teaching his class.

It did not take long for the students to realize that Terasaka is a pretty chill teacher and would not mind if they started throwing knives and toy grenades around the class. Unless they caused trouble and injure someone else, everything is fine and dandy. His ability to teach, on the other hand, turned out to be horrendous. It was as if the guy failed every single test during his time in highschool. That, or he just forgot everything that he had ever learnt. Nonetheless, the brunette still tried to conduct a few lessons with them and learnt alongside them. To be honest, it was actually quite fun, a situation where the teacher learns with the students.

He can be a bit insulting, too.

"You! The nerd over there!"

Emiru and Satomi looked up from their seats. For some reason, the triplets were wearing glasses that day, hence the reason why they responded to the word "nerd".

Terasaka sighed. "Not you. The nerd sitting at the back of the room, scribbling stuff into a book."

Everyone looked to the back.

Sitting in her usual seat, was Hayuka who was busy as usual with a pen flying over her "Book od Randomness", writing out some ridiculous fanfiction again, no doubt.

"You mean Hayuka?"

The blonde-haired girl looked up upon hearing her name. "Yes?"

"Wait, how is Hayuka a nerd?" Emiru asked incredulously.

Terasaka just shrugged. "She's studying. All nerds like to study."

"I'm not studying, why on earth would I do that?" Hayuka questioned, confused. "I'm just writing fanfiction. It's the last chapter of the one I'm working on, actually. The Fullmetal Alchemist one, though I am still working on finishing the Legend of Zelda fic. That, and I'm planning on writing one for the Marvel Cinematic Universe…"

The girl continued to rattle on about her ideas on various fanfictions she would like to work on while the rest of the class just sighed and resigned themselves to the fate of listening to Hayuka's ideas for another hour. Terasaka just nodded, a serious look on his face.

"She's not a nerd, she's a geek and a weeaboo."

"So, how did you come to know Shiota-sensei?"

Terasaka looked up. It was nearing the end of the day and he had proclaimed that the last hour is going to be a free period. All in all, he had done a pretty good job of teaching his friend's students. At the question, he frowned.

"Well, the both of us were classmates back in highschool seven years back. We still keep in touch all the time. In fact, there's a group chat with all of us discussing who's the next to be the next substitute teacher."

The class exploded with questions immediately.

"Wait, you mean all those people who taught us before were all your ex-classmates?"

"You studied together?"

"Even the teachers last time, what was their names again, were classmates of yours?"

The man nodded at all the questions. "Yeah, the ones last time were Kataoka and Hinata. Kataoka was our female class representative back then. I think she's now working as a flight attendant and Hinata's a gymnast."

Questions started pouring in from the students who were curious about their homeroom teacher and his friends, who were apparently his classmates from seven years back.

"Wait, what about that man from way back? The red-haired man who poisoned us with wasabi?"

"That's Karma, he's the class sadist. He's now a bureaucrat."

"That demon is a bureaucrat?!"

"You were friends with the famous Yukimura Akari? And the Tomohito Sugita?"

"Yea, but she was introduced to us with the name Kayano, and we all still call her by that name. Man, he was such a baseball freak back then. Now he's just a bigger baseball freak."

"And the French lady and her husband?"

"They were our teachers, obviously. Bitch-sensei taught us languages and Karasuma-sensei was our PE teacher. They returned to working in the government, though."

"Returned?"

"What about that AI machine thingy? How do you explain that?"

"Oh right, Ritsu was there to assassinate our teacher."

Silence.

"Did we hear that right?"

"Yea, you know. That's why Nagisa's always away. He's always being called in for carrying out assassinations. Damn, he's a popular one."

More silence.

"WHAT?!"

Nagisa smiled to himself as he made his way home. His mission went well, and everything was pulled off successfully. All he wanted to do right then was to head back home and rest, then prepare for his lessons the next day.

Checking the time, he noted that the school bell would ring soon, signifying the end of the school day and his students would be heading home. Hm, he should really contact Terasaka and enquire him about his day.

Just then, his phone's notification tone rang.

And again.

And again.

And it wouldn't stop.

Pulling out his phone, Nagisa frowned as he checked his notifications. There were lots of messages on his WhatsApp, and most of them were from his students' WhatsApp group.

Shinji Akari: Woi Nagisa!

Shinji Akari: You never told us that you work as a part time assassin!

Nagisa spluttered as he read the message. What has happened while he was away? Why did his students-

Hiroyama Emiru: YOU never told us that you were part of the class who was under threat of the alien being seven years ago!

Ito Kazuya: Yo teach, why don't you teach us the ways of assassination?

Ito Kazuya: It's better than what we are learning in school anyways

Otonashi Hayuka: Shiota-sensei!

Otonashi Hayuka: Your highschool life was so fun!

Otonashi Hayuka: It was almost like your life could be turned into a manga!

Otonashi Hayuka: I bet people would love to read the story of your life!

The conversation continued as more and more messages poured in from his students. Nagisa stared as cogs finally turned in his head and he let out a frustrated growl.

"TERASAKA!"

So... many of you were like "make the students find out that Nagisa is an assassin by someone randomly attacking the school and Nagisa decides to save the day by being heroic badass assassin". Well, that idea is too stereotypical for me. Nope. Instead, Terasaka spills the beans because he's Terasaka and he's dumb. I told you all I had special plans for him!

Now, who was expecting that ending?

Anyways, that's all from me this chapter and I am going to be working on the next and last chapter. This chapter will be a special one. Now, can anyone guess what it could be about? Till then, ja~

Yours,

BlueSkyBlue,

a.k.a Otonashi Hayuka
