"From today onwards, I'll be your PE teacher."

For students, there's nothing big about that statement. Oh, look! We got a new teacher who would teach us how to kill, not a big deal.

But for a certain teacher, that statement was like a provocation. Like an alpha from another territory tried to take over his domain.

No one knows from that simple statement, a clash would occur.

Flashback, shall we?

"Such a good day today ~~~ it's a good thing that I bring this ice (from the North Pole ) to make shaved ice. If only there's a lovely lady who would join me~~"

Suddenly, the students come from behind the trees and bushes. Running happily towards him.

"Sensei~~ the shaved ice look good!"

"It's unfair to eat that alone you know!!"

"Sharing is caring! So you should do too!"

Ahh... Such a lovely sight. To see his students running and smiling at him. Wanting to spend time with him. It makes the octopus cried in joy. He can not help it, okay! This scene was just heartwarming for his lone wolf heart!

Then, the heartwarming sight change into students attacking him with knives in their hands.

And in one moment, Koro-sensei disappeared and reappeared behind them and knives magically change into flowers.

"I would say that your idea was good but your acts are too stiff to drop my guard."

He dropped the knives on the ground.

"Please admire the flowers and learn to smile like them. Then, maybe you could drop my guard."

'Nurufufufu... Such a charming man I am~~ with this my popularity with them would boost in tenfold !' He thought in mind. Thinking that his students would look at him in awe or something.

But too bad... Reality and imagination were completely different. Even our mighty octopus couldn't change that fact.

"Nee... Sensei... Where do you get these flowers?" Kataoka asked. Her and some other girls eyes were hidden with shadows.

He and the boys sweat drops.

"Don't tell me that these are the flowers that we had growing up..." Her shoulders shook with anger.

Suddenly, tears drop from Yada lovely eyes. Her hand clasped her mouth. "That's horrible sensei... We had risen the flowers with so much care but only for you to pull out heartlessly...!"

This makes the octopus freaked out. To see tears dropping from his student - especially he was the one at fault - and guilt started to form inside him. "I'm sorry!!! I'll immediately go to buy some new plant bulbs right away!!"

He vanished and reappeared with some bulbs for them. The girls, with the eyes of predators, wouldn't lose this chance to give the octopus some payback.

"Flowers are fragile! You can't use your speed to plant them! It would harm them! Got it!!" Okano yelled at him.

"Please make sure you be careful with each of them!! Plant them like you taking care of your children!!" Kataoka gave strict instructions to him.

Anyone who saw this scene would definitely sweatdrop. The so-called octopus who proclaimed that he would destroy the earth was now being scolded by his students.

And some of them would scowl at this and thinking that the octopus was just being a goody-two-shoes to gain the students' acceptance. For them, the octopus is just a monster. Nothing more nothing less.

But, for a certain student, he saw this as one of the openings that can be used for his assassination attempt. He saw this scene as valuable information. Who knows, with every - even little - information he gained might give him a chance to strike and end the octopus for once and for all. Even how trivial and weird the info was.


Karasuma was walking towards the class E3 building since he received the mission to monitor and teach the students the fundamentals. This might not be his first time as an instructor but it would be his first time teaching some civilians.

As he arrived at the building, he greets a student - he believed her name was Kayano - and saw a completely absurd situation where the students tried to jab their teacher like some kind of pinata. There's some mocking and the branch broke, the students chased him and even with those numerous handicaps, they still couldn't touch him. Furthermore, they had the guts to be proud of this not so achievement! Granted, they were amateurs but ignorant and dreaming wouldn't bring help to assassinate him.

Any pro would either laugh or felt insulted if they saw this assassination.

He grits his teeth.

Nevertheless, he realised after watching this sad attempt, that some students didn't follow the others assaulted. The troublesome gang members and the three new students. This could be problematic, so he should ask them their reasons.

He walked to the students. "Everyone, I need your attention."

Thus the end of the flashback.

"Nuoooooohhhhh!!!! You can't do that!!!"

"Yes, I can." Deadpan Karasuma.

"But! But! But!..." Koro-sensei whining.

"Just accept it, sensei... When it's come to human capabilities, you suck!!" One f the students said.

"Remember our home economic class? He asked us to sew a clothe in a minute! A full body!!"

"How absurd..." The students started whining.

An arrow struck his heart. He couldn't say anything about that. That doesn't mean that he had to give up.

"Even so, can you teach, Karasuma-san...?"

A tick mark shows up on Karasuma's forehead.' This octopus sure is irritating.'

"I'm. I have a teaching license. So no need to worry."

"Nurufufufu... Having a license doesn't mean that you're capable ~~" the octopus taunting him.

Fuwa suddenly interrupts them by asking." Does Koro-sensei had a teaching license??"

The said teacher froze. This makes the students and a certain person who was soon to be a teacher deadpan at him.

"Nurufufufu... A...as I said... Having a license doesn't mean that you could teach..." The octopus tried to reason them.

"What are you saying koro-sensei... It's just the same with a driving license. You could drive doesn't mean the authority permitted you..." Nakamura chided.

"So, does that mean koro-sensei illegally teach us?" Yada asked out.

Everyone went silent.

"Well... His existence and most of his actions are illegal..."

They went silent again.

"Koro-sensei... Go get your license..."


Even until the end of the class, Koro-sensei didn't give up.

"Karasuma-kyun~~ are you sure someone as brute as you could teach the students ~~?"

"That's why I'm a PE teacher."

"There's no need for you to teach them! Am Alone is enough!"

"And let them do the pathetic assassination? They didn't even know the fundamentals. Forget about the assassination. If this goes on, even until the end of their lives, they would not be able to touch you."

'Ouch.' They all thought. That's harsh! But they did knew what Karasuma-san said was indeed true. They were amateurs in this assassination. Like a newborn baby who was about to come into the world. Wait, does that mean koro-sensei is the mother - since he is the cause of this assassination classroom - and Karasuma-san our father that teaches us to kill our mother to get the money... Ok. Let's stop these ridiculous images. Let's pretend that we never thought about this.

We never thought about this.

Overall, Koro-sensei attempts to bring down Karasuma were fairly failed - since he mostly ignored him- but for sure, he nearly pushed him to go to learn with a hermit or commit homicide.

Well, either way... It's fairly annoying.


"You three. Can I talk with you for a bit?"

Tsuna and his friends were walking in the corridor. They're about to leave when Karasuma-san suddenly approached them.

"What can we help you, sensei?" Yamamoto asked.

"Can you tell me why you didn't follow the class assassination before?"

Gokudera grumbling. "Which one? The fake smile or the monkeys using some sticks to poke a flower? If the latter, I already answered your question." He ended it with a glared.

'That's quite harsh.' He thought.

"Haha! Not in the mood, I guess..?"

'Such an easygoing answer'

" I afraid to be step by them...?"

'What the...' What with that answer...

"Haha, it's quite messy out there."

"Tch! They are just stupid."

"Gokudera..." Tsuna just sweatdrop.

Well, the silver head- Gokudera?- surprisingly had a good reason. And his answer suits his image. It's either he just likes the bleach's gang- who had lame pride to join the class - or he just simply thought that attempt was futile in the first place. For the black hair and the brunette... Just a lost cause... Well, it's a normal reaction he guesses? They came to school to study but ended up learning and trying to kill their teacher.

Now that he thought about it... The class reaction was not normal though.

They were too willing. In his case, it's better for him but in general... It's either they prepare to kill or...

They just simply playing...

Ahh...

He understood now... The reason he found their attempt today was irritating... They just do it. They merely do it. They didn't actually put their hearts into this mission.

As long as they thought a bit...

As long as they swing the knives...

Do they think only doing that would be enough?

Whether they were aware or not... It's not gonna change the fact that they were too naive.

Looks like he needs to alter his instruction for a bit.

"A...Are you okay...sensei?" A soft voice wakes him up from his thoughts.

He looked at the brunette. "Yes... I'm fine..."

"Then... Can you let us leave...?" He said hesitating for a bit.

"Ah... Yeah. You can go now. Thanks for conversing with me."

The brunette gave a bow and started walking but before Karasuma could start to dive into his thoughts again, the brunette and his friend suddenly said to him.

"Please take care of us, sensei!"

"Haha! We'll be in your care starting tomorrow sensei!"

Maybe becoming a teacher is not bad.


Tsuna hated his luck. He just wants to do his groceries in peace. That's why he told his best friends to not come with him today. - of course, with some verbal fight but he managed!- Thus, going to the market alone. He went to buy something for today and when he finished... Bam! The enemies appear!

It's the bullies.

"Well, well... Look what we have here~~"

"Kehehe~~ another victim has come!"

"Oi brat! Gave us your money or else... Meet with the lefty and the righty!"

The bullies tried taunting him while tsuna struggle to not cringed at this situation. He was already too used to this situation that he was kinda bored(?) Or faded up with this.

'Just hurry up. Do whatever you want and leave me already...'

Yeah, just leave him already... Leave him alone...

Alone...

Lone...

I don't want to be alone

Suddenly, one of the bullies plummets to the floor. Tsuna dazed out from his thoughts. In front of him, stand a tall redhead guy who gave a quite creepy smile.

"Ne~ you all~~ if you that bored... Why don't you play with me?"


"Thank you for helping me!"

The redhead smiled. "Nothing really... I just enjoy the fight ~ though, those guys just knew how to bark than bite."

'Wow... What with this scene of deja vu?'

'Ah! He reminds me of byakuran for a bit...'

"Even so... You still helped me. So, I'm grateful to you." He gave a soft smile. Tsuna went to one of his plastic bags

And pull out something.

A chocolate bar.

"Here! You can have this!"

The redhead's eyes lit up. "Eh~~ really ~~ Then, I'm gonna take it." He took it, opened the wrapper and ate it.

"Then... Thanks again. But I need to go home now or my friends will be worried about me." He said as he prepared to leave.

"Sure! Hope when we meet again, you are not in trouble."

"Haha... No promise..."

As the two walked in opposite directions, they realised at the same time.

'Ah... I didn't get his name...'


Karma knew that he was different from most of the kids. He absorbed his studies more easily than other children. He's also quite strong and knew how to utilise his knowledge and surrounding to his advantage.

But... You see... Karma is also a violent person. Yet, he didn't want to be a bad guy. After all, he likes heroes. So what should he do?

The answer is quite simple.

He became the bullies' tormentor. After all, heroes are the villain's taunter.

With that, he can become violent and be a good guy at the same time. And when the teacher in his class support him. Saying that he would be on his side as long as he is in the right... It's made him fluttered and proud of what he's doing.

' That's right, teachers are someone who would protect, support and educate you. If you're in the wrong, teachers would correct them.'

' Teachers are someone with high morals. They wouldn't be swayed by money or other things.'

' They wouldn't betray their student's trust. '

And Karma trusted that ideology for a long time. Until that faithful day...

He saw the teacher's true face.

And when that ideology crumble...

All people that called themselves as a teacher were dead to him.

That's why when the opportunity for him to kill a teacher came, he couldn't let the chance escape. After all, he couldn't kill that teacher - since that person killed his existence as a teacher by himself.-

' Welp, since teachers are the same either way... So killing him is like killing that thing.'

He will kill the thing called a teacher.

Just like how that teacher killed his trust.


"Alright, you all. Today we will learn how to swing a knife and getting used to it." Today was the start of Karasuma's first instruction.

First, he needs to implant the importance of basics on them. Basics are easy to overlook in general. Furthermore, it looks boring for the beginner such as those students. When people saw someone did some incredible techniques, they would usually try to copy it with a mind that he too could do it immediately. Doing that would lead them to cause some harm to themselves. He wanted to avoid that.

"As I said, you will learn how to hold the knife, the posture when you swing it and make your body remember the movement smoothly. Is there any questions?"

Maehara immediately hand's up. "But sensei... Is there's any reason to do all that? Furthermore, with the said target watching us..."

The target, Koro-sensei was watching the students like a hawk in a gym uniform. It's quite disturbing...

"Target! You're disturbing the class! Go play with the sand there!" Karasuma yelled at him.

"Nuoh!! But I'm just watching you all!"

"Your gaze itself is creepy." He retorted.

"That... That's cruel... Karasuma-sa... Karasuma-sensei... Just so you know, my PE class are not that bad!"

'Liar!!' All students retorted in their minds.

"Whatever. Right now is my time. You shouldn't disturb your colleagues class. It's not like I'm doing something bad."

'Well, teaching students how to kill is bad enough...' Tsuna silently responded.

"Back to the topic..." Karasuma ignored him.

' Uwaah... He ignored him...' The class sweatdrops.

"The reason that I'm teaching you this is that fundamentals are vital towards your skill. It's just like studying. Without knowing the basics of your subjects, you would not be able to answer the test." He looked at Isogai and Maehara. "Both of you. Come and attack me with all you got."

Isogai hesitate. "Is it okay...?" Maehara also thought the same.

"It's fine. That knife would not be able to hurt humans."

After hearing that, both of them immediately attack him but Karasuma was able to dodge it with ease. He gave his speech as he deflated all the attacks that came to him.

"In kindergarten, you learn the alphabet and numbers."

Isogai tried to sneak attack and failed when Karasuma avoid it.

"In elementary, you learn how to read and counting."

Maehara strike his head but Karasuma shoved his hand away.

"Without knowing all that, you will not be able to learn something more advanced."

Both of them strike at him. Karasuma immediately holds their hands and yank them to the earth.

"It's the same with every technique in this world. Without knowing any fundamentals, you would not be able to hit me or any enemies that may come... Or that target. When you're able to hit me, your chance to kill him might increase."

All of them gaped at him.

Karasuma assist both of his students that he had yank to stand. "That's why in this PE, I'll teach you about many necessary skills for assassination. From handling knives to using guns."

The students could only gape at what they had seen and heard. Yamamoto was smiling in excitement, Gokudera had a serious face on him while Tsuna felt kinda down for some reason.

' I don't want to be disappointments...'

"Now that you know it, let's start the exercise!"


After the class, Koro-sensei watch his students talked excitedly about the PE class or how Karasuma sensei looks cool or something.

Koro-sensei gave him crocodile tears. "Karasuma-sensei... Are you trying to take away my popularity with my students...?"

"Don't be absurd. [ if the school chooses... It could add teachers in the design subject to class E.] That's a condition for your teaching contract."

He threw a knife at him. Of course, Koro-sensei dodge it. "But yesterday, your actions said otherwise. You should know that I come here to oversee these hitmen and you for the purpose to kill you."

The neverending smile was silent for a bit before he started to talk. "Nurufufufu~~ I may have said that but doesn't mean that I like it. After all, I'm quite fond of the benefits of the doubt. Furthermore, it's not you or the target. Please call me Koro-sensei from now on. After all, this name has been picked up by my students ~~"

Karasuma is just quiet.

"Pretty please...?" He sweatdrops.


The students were preparing to leave when suddenly a boy come into the view.

"Karma-Kun... looks like you've return..." Nagisa said.

The redhead, karma gave a cheery smile. "Yo, Nagisa-Kun. Been a while~"

Then, he looked at Koro-sensei and walked towards him.

"Hee~ So you're the famous Koro-sensei? You're just like what I had heard."

The octopus and the brunette were surprised when he saw him.

'The redhead from yesterday!'

"You are... Akabane Karma-Kun... I heard that your suspension ended today..." His skin turns colour. " but late on your first day is no good, you know!!"

Karma gave him an apologetic smile.

"Sorry... It looks like I need to get back to the rhythm of school life..."

He extended his hand to the teacher.

"It would be more relaxing if you call me by my first name. Anyway, nice to meet you, sensei..."

Koro-sensei beam. He reached karma's hand as he said." Same here. Let's have a good and interesting year-"

But his words were cut down when suddenly his tentacle meltdown. This gave everyone who saw it a shock reaction except karma himself.

Without missing a beat, he immediately pulls out the knife hidden under his sleeve and attack him with a maniac grin.

Koro-sensei who realised it immediately move away from him.

Sweating profusely.

Everyone was speechless. It's the first time they saw the invincible koro-sensei getting hurt and lose his composure! By a mere student nonetheless!

It looks like the class assassination would not be that dull.


"So, how's your day today?" Reborn asked them at dinner.

Yamamoto who was chewing his food stop to answer him. "Interesting I would say. We got another student this time."

For some reason that Tsuna didn't know, Reborn would start a conversation about their daily life. He would ask, "how's school?" Or " how's your day?" And so on.

Reborn could know it without them telling him. So why?

"Tch. The Karma guy just taunting that UMA before left the class."

"Well, he might have a personal grudge or something. Right, Tsuna?"

"Eh? Ah... Maybe...?" Seeing that uninterested reaction, they frowned.

"What's wrong, tsuna?" Yamamoto asked.

But tsuna's just quiet.

"Dame-tsuna, if you didn't say anything, no one would understand what you want," Reborn told him.

There were many things that Tsuna want to say.

'Why did you send me here?'

'Why did you bring Gokudera and Yamamoto?'

'What do you know about this situation?'

'What are you hiding?'

'Why suddenly you become thoughtful?'

But Tsuna didn't tell them all the questions that plagued his mind.

"Nothing..."

Just one word that he could mumble.

And Reborn knew his student's concerns. Of course, he could. His student is a bad liar. That's why he executed this plan.

Now that they have all the time they need. He didn't need to rush just like in the past. This time, what his student need was not high education.

Neither is a pressure.

Reborn is not a slow educator. But, if that what's it needs to make sure that Tsuna wouldn't break... Then, he would slow down. All for this lovable dame-student. Welp, he better appreciates his efforts later.

"I knew that there is something but I'm not gonna push you. However, remember Tsuna. Don't forget what I just said. Unless you speak, no one would know."

The dinner goes on.
