Well, I'm sorry that I took this long to upload... Life is just distracting. Also, this was actually almost finish since months ago, but there was just something that was missing about it, which is why it took this long for me to upload. But anyways, here it is! The final chapter for this fic! There will be more chapters about other random ideas I get for the fic, but I have officially marked this fic as completed with this chapter. I'm working on my other ideas which are sadly not anime fics. It'll take some time before I write more fics as I'm just trying to figure out a schedule for myself and not get distracted by my Nintendo Switch or Kdramas or reading fics instead of writing them. Welpppppp.

Well, just enjoy the chapter!

Kayano: So…

Kayano: It's that time of the year again, huh?

Nakajima: Yep

Nakajima: I might be late though

Nakajima: Catching the earliest flight to get there as soon as I can

Isogai: Maehara and I have already informed our customers that we are going to close shop

Nagisa: It's a school day

Nagisa: Would you guys mind if I brought my students along?

Yada: I wouldn't mind

Yada: The more the merrier!

Kataoka: Sure bring them along

Karma: I shall bring my wasabi

Nagisa: Karma!

The students of Class 3-5 were anxious and excited. Their homeroom teacher, Shiota Nagisa, had announced a few days prior that he was going to be bringing them out on a one day outing that day. He told them to bring some extra clothing and pack some food with them. He also told them to meet him in front of the school gate that morning. It is clear to say that the students were wondering what their teacher was up to.

They did not need to wait long before the familiar figure of their homeroom teacher came into sight. Simultaneous greetings of "Good morning" and variations thereof were exchanged.

"Good morning, everyone!" The teal-headed man smiled as he did a head count, making sure all the students are present. "Now, we don't have a means of transport to our location, but it should be easy enough to head there on foot. When everyone is ready, follow me."

Their curiosity grew as they followed their teacher, crossing roads and passing by shops. Finally, they reached the foot of what seemed to be a forest located at the foot of a mountain.

"It'll be trickier to navigate up, but take your time," Shiota-sensei told them. "As long as you follow me, you won't get lost."

With that, he jumped to a tree branch and began making his way up the mountain, swinging across the trees as if he was Tarzan. The students stared after him. It was no longer a secret that their homeroom teacher is a part-time assassin. They were constantly in awe of his flawless skills when he demonstrated them in class. However, this was the first time they saw him moving with such agility.

Shiota-sensei stopped, looking back to them. "Come on!" He hollered. "I'll wait up for you."

The first one to move, unsurprisingly, was Kazuya. The boy was a fanatic when it comes to parkour after all. With a whoop, he began mimicking his teacher, successfully pulling off his launches, catching himself in time to swing across to another branch and rolling to cushion his falls. Soon after, his best friend, Akari followed. The rest of the students were more cautious, as they were not as athletic as the two boys. Some, like Satoshi, were light on their feet and could make their way up through the rough ground. The rest just trekked up slowly, careful not to slip and hurt themselves.

It took a while, but at last, they reached a large clearing where a lone wooden building stood. The exterior looked rundown, with several places on the rood and a few windows boarded up.

"Yo, Nagisa!" A voice shouted out from within the building. "You're late!"

Nagisa's face lit up. "Maehara-san! It's good to see you again! The others are already here?"

A figure walked out, revealing a familiar woman with green hair. "Yea, you're the last one to arrive. Everyone's here already."

The students recognized the two people, having met them before. These were their homeroom teacher's classmate when he was in highschool. And from the sound of it, all of his ex-classmates seem to be present in the location with them.

Where were they, anyways?

"Everyone," Shiota-sensei spoke, interrupting their thoughts. "Welcome to the Class 3-E. My classroom when I was your age."

The students were not even surprised anymore. After hearing about their teacher's past and also experiencing the bizarre events since he started teaching them, there was really little that can shock them. Looking around, it was a situation similar to that of their own where the class of troublemakers are far removed from the general student population. It is a wonder that Shiota-sensei managed to graduate and become the teacher he is now, respected by his students.

"Right then," their attention was drawn to Toka Yada as she clapped her hands. "There's a box of cleaning supplies in the main hallway. Everyone! Grab something from there and let's get started. With this many helping hands, we should be able to finish in two or three hours and hang about after!"

The students stared at her for a minute before groaning and started getting to work. After all, they wouldn't dare piss off any of the adults there.

Okajima yelped as a pair of scissors narrowly missed his right ear, embedding itself at the tree behind him. He backed away as a pair of indigo eyes narrowed suspiciously at him.

"If that camera comes anywhere near us, I would not hesitate to fling the next one right into your throat," Natsuka threatened as she pulled out another pair of scissors from god knows where.

"Yes, yes!" Okajima squawked. "What in the world has Nagisa been teaching you all? This is not a life or death situation! There's no need to train another class full of assassins!"

The female class representative just kept her eyes trained on him for another good minute before returning to cleaning the windows with her friends.

…

Students ran in fear as they were chased by none other than a vicious Karma who decided to pull out his infamous tubes of wasabi and mustard with the intention of force-feeding the stuff to the students.

"Hide yo kids! Hide yo wives! He's after us!"

"RUN! THE DEVIL HAS BEEN AWAKENED!"

The screams of horror and malicious cackling only stopped when their chibi teacher stepped in and disarmed the red headed man, telling him off as he did so.

…

Kayano squirmed uncomfortably as a small squad of fans crowded around her. Questions were thrown from left and right to the point that she could not keep up with the tirade of inquiries.

"Akari-san! Can you please take a selfie with me?"

"Do you have a boyfriend? If no, do you have a secret boyfriend?"

"Fuck, marry, kill: The Avengers! Seriously, who would you like to get some with from that group?"

"Are you going to star in another movie soon? Like, I really liked it when you starred in Itazura na Kiss and that one time when you were Uraraka Ochako in that My Hero Academia live action. Also, you looked so cool when you were playing Yuno from Mirai Nikki. Like, you were so cool!"

"OH MY GOD. I STILL HAVE NOT WASHED THE AUTOGRAPH OFF MY BUTT YET! THIS IS SUCH AN HONOR! WOULD YOU LIKE TO TAKE A LOOK AT IT, AKARI-SAN?!"

…

The triplets gawked as they watched a robot manoeuvre itself around the multiple people in the place.

"Yes! Itona, the code that you have implemented for me to move around is superb!" Ritsu exclaimed as she made her way around. "What else have you implemented into this thing?"

The platinum blonde haired man jotted down notes into a notebook as he replied. "Oh, there are some guns in the upper chamber of the body, amongst some of them is a Colt 90, a M4 Carbine Commando with a M203 grenade launcher attached to it and a Ceska Zbrojovka Scorpion EVO3. There're also some sedatives in the bottom chamber. Your camera also allows you to look around in the dark, scan for heat waves and record activities."

Yep, they definitely did not need to know more about that. Why is the robot even equipped with such a large arsenal of weapons anyways?

…

"Here you go… I have one for you too! And here's another for you!"

The small group of students stared dumbfoundedly as Hara handed out packed bento boxes to them. They were wrapped beautifully with insulated cloth to keep the food warm and upon opening the boxes, they were greeted by a scrumptious sight. Half the bento was filled with steaming hot rice while the other half was filled with tamagoyaki and chicken cutlets along with some cherry tomatoes.

"Go on! Eat up!" Hara urged. "I spent a lot of time preparing those for all of you. Now if you will excuse me, I'm going to give out the remaining bentos to the rest! See ya'!"

…

"Oh my goshhhh! That scene was too cute, let's rewind and watch it again!"

A group of girls were gathered around Fuwa as they all watched a Youtube video featuring a group of men dancing and singing a song. For some odd reason, they thought that kissing each other every few seconds was a good activity to show in the video.

"That kiss was phenomenal, and that's kiss number twenty-one of the music video!"

"Did you see that kiss he gave that guy while lovingly holding his head in place?"

"I just realised that this was in a church and they are all wearing religious outfits. Whoever came up with the setting is a genius! The BL is so great!"

…

Terasaka gulped as he mopped the floor of the staffroom. Behind him stood Nagisa who was dusting the shelves using a feather duster. Aside from the occasional sound of squishing when he wetted the mop and squeezed it dry, the room was silent as the two ex-classmates cleaned the room. However, the dirty blonde headed man can only feel chills up his spine as he continued working away on the floor.

"You know, I do not recall giving you permission to tell my students about my other profession," Nagisa said nonchalantly.

Terasaka froze.

The tealnette paid no attention to him as he continued talking, somehow managing to make the feather duster he was using seem like a lethal weapon. "Imagine my surprise, finishing up my job when I suddenly get bombarded with thousands of notifications from my students questioning me about Koro-sensei, about the times we spent with him seven years ago."

He was afraid to turn around, for fear that he would witness an angry Nagisa ready to wallop him with the feather duster.

Nothing happened.

"I would really appreciate it if you avoid doing something equally stupid in the future," Nagisa said at last.

Terasaka let out a breath that he did not know he was holding.

"However," the tension in the room was back once more. "If you do commit something of an equitable moronic degree, I would not hesitate to kill you in your sleep."

…

"So, I believe we have not been very well acquainted the last time I was substituting your class," Nakamura said as she suddenly appeared before a group of students. "After all, I was under the disguise of a large yellow octopus. Did you all enjoy that prank?"

The startled students just shook their heads as they eyed the woman warily. This was the woman who traumatised them by dressing up as an alien and harassing them with it. There was no way that they are going to let their guard down around her.

"Oh, come on!" The blonde headed woman beamed at them. "Y'all are looking at me like I killed a puppy in front of you! Aren't you guys like, you know, the troublemakers of the school or whatnot?"

Silence.

"…Well then! I guess I'll just go prank some other people who would probably have a better sense of humour than you guys!"

"…Shiota-sensei?"

The teal headed teacher looked up. "Yes?"

"So the next time you'll be going off on an assassination assignment, it'll be one of your friends who'll be substituting, right?"

Nagisa hummed in agreement.

"Like, there will be anyone else that will be substituting for you, right?"

"Nope, no one that I can think off."

It was another school day in Paradise High School. It was early in the morning and the first period was not in session yet. The students of class 3-5 were happily conversing with each other, unfazed by the numerous non-lethal weapons being thrown about the classroom.

The door opened and a man with strawberry blonde hair walked in. He looked rather handsome, especially since he was wearing a formal suit. However, the students were just confused and curious. Did their chibi of a homeroom teacher get called away for another assassination assignment again? They did not recognize the man standing before them at all.

"Good morning, students. My name is Asano Gakushu, and I will be your substitute teacher for the day."

Well, shit.
