Hey everyone! BlueSkyBlue is back! I am so so sorry for the long wait! I have been really busy with life, and this year is an important year for me as I have some major exams coming. I cannot guarantee frequent updates. Still, I am trying to keep updating. Just to notify you guys though, I will not be updating at all from September to December.

Anyways, most of you guys should know this already but this is the companion fic to When Nagisa Goes MIA. I will not be updating this as frequently as I do with my other fics. Another note, this fic will be completed when When Nagisa Goes MIA is completed.

I will try to update When Nagisa Goes MIA as soon as possible, but there are no guarantees.

Once again, I apologize for the late update. Enjoy the chapter!


Teaching is a tough job no doubt. Having to teach a bunch of students while trying to keep them quiet and under control is hard. However, Shiota Nagisa loves his job and he would not trade it for anything else.

Well, except for the once in while assassination trips he had to go on for the ministry. He could not say no to those...

Of course, Nagisa cannot deny that teaching is a job full of obstacles. There was always a student that would have some problem or another. Not to mention the weekly meetings teachers would have on Mondays afer school about the progress of the classes they are teaching, which Nagisa found was a big waste of time.

Ever since his first day of teaching, Nagisa had taken in upon himself to educate the 3-5 Class of Kunigigaoka School every subject there was on the syllabus, seeing as the the other teachers were afraid of even walking into his class. Of course, with his time taken up by the class, he was unable to teach any other classes in the school. That was taken care of with the help of Karasuma, who had "walked" into the principal's office a week after Nagisa's teaching carreer, document in hand to describe how dangerous it is for an assassin to have a relationship with too many students and what not.

But Nagisa is happy, so nothing else matters.

And since then, the students of Class 3-5 Paradise High have learnt a lot about their chibi of a homeroom teacher.


(Never call Shiota-sensei "short", or anything that implies that the teal headed teacher is shorter than the average guy of their age.)

It never escaped any of the students attention that their homeroom teacher is really short. In fact, he is even shorter than the shortest male student in the class. It really amazed everyone that their teacher is actually a twenty-one-year-old man who had studied in a university, not a wannabe middle school student trying to play a prank on them.

It happened on the second week after Shiota-sensei became their homeroom teacher of the year.

They were causing a ruckus, as usual. After all, they are the troublemakers of the school, and they got to live up to their reputation. No matter how hard the board of teachers tried to handle the issue by transferring some smart students to the class, it was to no avail.

It was at that moment that the door slid open and Shiota-sensei walked into the class, silent as usual with a file in hand. It baffled the class how the teacher was able to walk along the wooden floor without making any noise. The way he moves were like a snake, silent and deadly.

Yes, they were well aware that their teacher is not one to be crossed. His demonstration on the first day of his teaching job clearly left a significant mark on them.

The class fell silent.

Shiota-sensei greeted the class and started taking attendance. When he finished doing so, there were a few minutes of homeroom left, to which the students used to badger their teacher with many questions.

...

"Shiota-sensei, which school did you study in when you were our age?"

"Kunigigaoka High School."

"You are lying! That school doesn't exist!"

"It shut down a year after I graduated."

...

"Shiota-sensei, what are your hobbies?"

"I quite like researching, if you can count that a hobby."

"Researching? Shiota-sensei is a geek!"

"... Extra maths homework for you, Kikuchi-kun."

...

"NAGISA!"

"What is it Akita-kun?"

"Look where you are walking to, you idiot! Why are you so clumsy?"

"Because it's my middle name."

...

"Shiota-sensei, why do you always carry that notebook around with you?"

"It's my Death Note in disguise."

"... You are not serious, are you?"

"Just kidding, I'm just used to carrying it around with me, I guess. I have been doing this since my high school days."

...

"NAGISA!"

"What is it this time, Akita-kun?"

"Hurry up and start class!"

"Class will be starting soon. Also, refer to me as sensei next time."

"Tch, the day when you stop being clumsy."

...

"Shiota-sensei, why are you so short?"

It was as if the temperature in the classroom had dropped by a few degrees. The students gulped as their homeroom teacher let out a dark aura around him.

Then Shiota-sensei strode over to the student who had uttered those words and pressed a rubber knife at his throat.

"Care to repeat those words, Soichiro-kun?"

Every one shuddered at their homeroom teacher's voice, which seemed as if it had adopted a bloodthirsty tone.

That day, Class 3-5 of Paradise High School stayed back after school, trying their best to calm down their irate homeroom teacher who seemed really touchy to the subject of his height.


(Shiota-sensei has the ability of reading their emotions and intentions.)

"Natsuka-chan, please do refrain from using your scissors in my class."

"...I wasn't going to."

"I understand that Haruhiko is being a total douchebag at the moment. You can take care of him during break time. Until then, your red scissors stay in the left pocket of your skirt."

"...Yes, sensei."

...

"No matter how much you hate History, please pay attention to class, Hayuka-chan."

"I'm not!"

"...What page are we on?"

"U-um..."

"My precise thoughts. Stop writing fanfictions in that notebook of yours and pay attention. Your readers can wait."

"Yes, sensei..."


(Shiota-sensei wore a wig for a whole period once before realising that he was wearing it.)

The classroom was full of lively chatter as the students talked to each other during their lunch.

Then the bell rang, signalling the end of lunch time and that classes are about to start.

Yet, Shiota-sensei did not show up.

He did not show up for English class and arrived panting heavily give five minutes into their Mathematics class.

The class stared.

Shiota-sensei was wearing a wig.

The boys in the class gulped, questioning their preference about the opposite sex as they had perverted thoughts of kissing their teacher against the wall.

Shiota-sensei was embarassed when he found out he was wearing a wig for the entire Mathematics period. He even made them promise that they would not tell anyone else about the wig.

They spent the entire day teasing him.


(Shiota-sensei is a neat freak.)

The students stared as their teal headed teacher dumped a large plastic bag full of cleaning materials in front of them.

"We will spend the entire day cleaning up the classroom. You will not be allowed to go home until the classroom is spotless and everything is arranged neatly. Please begin immediately."

That day, Class 3-5 changed drastically. The students had to repaint the graffitified walls and scrub the floor till it was clean. The table were arranged neatly and seating arrangements were made.

The students of Class 3-5 did not leave the school until 6pm that day.


(That one time when Shiota-sensei was absent was fun, but they paid the consequences.)

"Shiota-sensei is unavailable today, so I'll be taking over for him just for a day," the substitute teacher, Misa Kazawa announced.

Operation Scare-the-Teacher begin.

After nine hours of "teaching", Misa Kazawa left Class 3-5 with paint in her hair, scribbles on her clothes and unable to speak a sentence without stuttering and stumbling over her words.

Shiota-sensei was furious.

"I have many friends," he had said, his voice quiet and deadly as he spoke to them. "I have many connections, be it a ministry officer, a lawyer, a doctor or even a yakuza. If I pull some strings, it would be no problem for me to destroy your families and friends just like how you destroyed the substitute teacher's mind. This is my last warning. The next time something like this happens again, you can say goodbye to your parents and siblings because they are going to end up in a mental hospital with no recognition of ever being related to you."After that, Shiota-sensei sent them to run around the school compound for half an hour before sending them home.


It took them a while, but the students of Class 3-5 slowly started respecting their chibi of a homeroom teacher. They would joke around with him a lot. They also learnt many things from him.

But they cannot say that they approve of the constant bizarre substitute teachers they often had when their homeroom teacher is absent.


And that's it for this fic! I hope you guys enjoy! Till then, ja~
