I shouldn't be starting another fanfiction with so many uncompleted fictions, but I couldn't stop myself from typing this out.

I did a Assassination Classroom fanfiction of KarmaxNagisaxAsano(Gakushuu) so I thought, ' Why not make a Koro-senseixNagisaxAsano(Gakuho)? ' But somehow this fiction is veering itself into becoming a general fiction.

If someone asked me who was the most handsome guy in Assassination Classroom, my answer would be undoubtedly "The God of Death. Aka Koro-sensei." So, I wanted to do a fiction with him as one of the main characters, so I wrote this out.

Of course, I'd still be updating my Trouble Time(With updating speed so slow you'd think it was written by a sloth.), but school is draining my stamina and I wrote this 2k word chapter in like, 3 hours?(I wonder how some people writes 10k words for a chapter) in the middle of the night. Yup, it's around 5am in my area. Why am I not asleep yet.

*If anyone wants to beta this, I will welcome you with open arms(same goes for Trouble Time.)*

*Anyone is welcomed to give me an appropriate title for this fanfiction. To be very honest, no solid sounding titles came into my mind while writing this story, so a little help here please?*

Disclaimer: I do not own Assassination classroom. (I'm only going to include the disclaimer in the first chapter since it's what people see when they click on this fic.)

Whelp anyway, enjoy~

Something was wrong with Class-E's form teacher.

That, even the air-headed and oblivious Nagisa could tell. After a month of being a student teacher under Koro-sensei, Shiota Nagisa was sure that there was something weird going on with the teacher he was learning under.

It started with just a weird flowery scent that clung onto Koro-sensei's self when Nagisa walked beside the male teacher. Maybe it was weird for a male to be sniffing another male's body, but Nagisa could not help himself. Since he was born, Nagisa had a unique sense of smell and Koro-sensei's flowery scent did not help his sensitive nose.

Nagisa tried his best to ignore the fact that the type of flower he identified off Koro-sensei's body was of a poisonous type, but he couldn't help but let his gaze wonder to the black haired teacher whenever he saw him by the corner of his sight.

"Is something wrong?" Koro-sensei would sometimes ask, voice tinted with fake kindness Nagisa could easily identify. "If you need my assistance, do inform me. I'd be happy to help."

"No, it is nothing of importance, thank you," Nagisa would reply, because he had a feeling that whatever Koro-sensei was up to was of no good. Nagisa wasn't the type to dive into trouble, especially when his intuition was screaming at him to get away from the other male.

But Nagisa was curious. Why would a teacher be covered with the scent of Ricinus communi?

After a day, the scent on Koro-sensei became so unnoticeable Nagisa had to do a double take when the teacher walked into class. Class roll in hand, the tall and handsome teacher was rid of any kind of dangerous smelling plant, and Nagisa wondered for a brief moment, if he had imagined the smell from yesterday.

Even so, the memory of the scent lingered in his mind. Without any promptings, the idea of Koro-sensei being involved in something dangerous formed itself in his head.

A week passed without anything happening, but by the third week, he saw a bloodied vase right by the side of the headmaster's desk. When he passed the room by to enter the meeting room, Nagisa would have never thought that entering the headmaster's room without any permission would lead him to discover a dirty blood stain on the famous prized vase. It was small, hidden and veiled, but Nagisa took notice of it nonetheless.

He had decided to pretend that he hadn't seen anything, but his luck was against him when he found out that Asano-kouchou* took a medical leave on that very same day. Instantly, Nagisa felt himself to be getting even more involved with whatever Koro-sensei was doing.

That day, Nagisa willed himself to believe that the only reason why he went to visit his employer was because he was concerned with the older male, not because he was curious or dubious.

He had also willed himself to stop a blush from forming when Asano-kouchou smirked knowingly at his relentless questioning. Since middle school, Asano-sensei has had the habit of teasing his shy student whenever they crossed paths. From his height to his personality, Gakuho Asano always had something to tease Nagisa with.

Even after so many years, Nagisa still couldn't get angry with his ex-teacher who had helped him so much in middle school. Although Asano-sensei had undoubtedly changed a lot since he last saw him during the funeral, Nagisa believe that the kind and friendly teacher who had helped a bullied him was still there, no matter how much more manipulative he had become-if the sawtooth leaf pin pinned on his neck tie was of any evidence to Asano-sensei's lingering affections towards his students.

Shaking his head rapidly in denial when his teacher(Employer now) implied that he had an attraction of sorts to Koro-sensei, Nagisa sighed in relief when Asano-kouchou decided to drop the topic. Discreetly, Nagisa took a glanced at the clock by the table and winced. It was already seven-thirty, and he doubted that his mother would have cooked him, her 'unfilial' son, any dinner. It wasn't his fault they accepted him as a teacher before a professor when he had signed up for the job.(He had just wanted to go against his mother once, and lied to her about his acceptance that's all. Never had he thought that one lie would end up in such a disaster.)

He was about to excuse himself when Asano-kouchou invited him for dinner.

Even though Nagisa had wanted to refuse the invitation with the excuse that he would be bothering Asano-kouchou's family time, Nagisa thought better of it and accepted that invitation. He was hungry, and there was no homely cooked meal at home waiting for him , It was nice to eat a meal with the company of someone for a change.

Taking a seat right beside the uniform wearing teen, Nagisa gave the frowning(Suspicious; his brain supplied) boy a smile, hoping to dispel any sort of unfriendliness that oozed off his employer's son. He gave himself a cheer at the back of his mind when Asano-kun gave him a smile in return.

Starting a small chit-chat when the topic on the boy's day, Nagisa found himself quickly getting comfortable with the boy who seemed like an exact replica of his father. Not an exact replica, he quickly switched the way his brain labelled the younger Asano when he realised he was being very rude to both Asanos. The longer he chatted with the young man, the more he realises that Asano-kun is similar, yes, but at the same time very different from his father.

While Asano-kouchou was a man filled with ambition and confidence, Asano-kun was someone with charisma and although he seems as though he was trying a bit too hard, Nagisa could tell that he was going to be as good as his father in manipulating people someday- which isn't a good trait at all, Nagisa decides, when Asano-kun once again tried to change the topic to himself.

He was having fun playing with Asano-kun when Asano-kouchou placed a plate filled with mushy rice and omelet that looked too crispy to be edible in front of him.

"I apologise for my lack of cooking skills," was the curt-as if Asano-kouchou didn't want to admit he had a fault- apology given to him and all he could do was smile at the nostalgia that hit him. He had eaten Asano-sensei's handmade lunch box when he was still a student, and is glad to find out that the taste hasn't change.

Nagisa took a peek at the teenager's face and concluded that this must be a very rare occasion for the young boy. After Ikeda-kun's death, Asano-sensei had never been the same. Even so, Nagisa wanted the kind teacher he knew back. It was thanks to Asano-sensei that Nagisa inspired to become a teacher after all. He wanted to help students who had all sorts of problems, and teach those who never had any. He wanted to remind Asano-kouchou that teaching someone to be 'kind' is never a action.

Asano-sensei was the one who helped him when he was in need of help. Now, it was Nagisa's turn to help his ex-teacher who looks as if he is still in pain because of his student's death. Nagisa is sure that if he was still alive, Ikeda-kun wouldn't have wanted Asano-sensei to drown himself in self-loathing, self-hating, even changing himself into someone who used people as if they were disposable items; so that a repeated tragedy would never have to occur.

The reason why he had signed up for a place in Kunigigaoka Junior High when he was offered better paying places was because of his ex-teacher. He had wanted to help the teacher who had helped him. Repay the kindness he received with kindness he could provide.

Nagisa wanted the students to see that side of Asano-sensei he saw when he was still a teenager. Moreover, He wants Asano-kun to have a better relationship with his father. His relationship with his parents is horrible, and he doesn't want any teenager having a bad familial relationship like him.

And the first step to that was to get a closer relationship with Asano-kouchou.

Picking up the smoothly carved chopsticks, Nagisa placed the glass of water down and continued with his burnt dinner, then starting small conversations which, is a great way to make up for lost time with his ex-teacher. Getting to know his son is a welcomed addition.

However, Nagisa would have liked the occasion even better if the father-son duo would just stop throwing insults at each other across the table. He had held back his tongue when they reached a few sensitive topics, and pinched himself under the table to prevent his outburst from ever happening.

The reasons? One, he might lose his job. Two, it was rude to the person who had invited him for dinner. Three, he still wanted to form a amiable relationship with the both of them.

Ignoring Asano-kun's crude language of calling his father a womaniser, Nagisa continued to nibble at his food, grateful that he was able to enjoy his food surrounded by noise; albeit a bit too colourful for his liking.

His eyebrows twitched when Asano-kouchou suggested his son to visit the red lights district for a change, but Nagisa turned a deaf ear to it in favour of trying to chew his half burnt omelet.

Really, these two could score perfects on their examinations, but can't even cook a simple dish. Judging from how Asano-kun did not use his father's cooking skills as an insult, Nagisa could take that hint and form the conclusion that Asano simply did not want to call the kettle black.

Eyes facing down, Nagisa forced himself to not notice the lack of female present in the room. Nagisa thought back to how he would have brought up the topic of his employer's deceased wife when he was chatting privately with him just now, but knew better when he did not see a single picture of her when he went down for dinner.

Nagisa had a huge suspicion that the framed photograph that was facing downwards was of Ikeda, not of his wife.

A small part of him was still curious. Why would Asano-kouchou not pin up a single photograph of his wife in his own house? Not to mention the lack of a wedding ring on his ring finger... But Nagisa knew that he shouldn't bring the topic up with the teenage boy still in the same room.

Mrs Asano was a kind lady, and Nagisa had never met the nice lady who gave him plaster when he fell, a second time.

.'.'.'.

"When did Koro-sensei started working here?"

Asano Gakuho knew something was wrong when his ex-student asked that particular question. Although he shifted the topic off to something lighter, he knew that he won't be able to hid anything from Nagisa if he truly wanted to know.

He invited Nagisa for dinner-something that he had never done ever since the death of his student, Ikeda.

He had never eaten dinner in his own house ever since that fateful day, always choosing to dine with politically influential clients over his own son. He needed the power. He needed the money, to build his perfect world. But Nagisa is always an exception.

He still remembers the first day when he had met the boy, bruised and hurt in such a terrible way that he had saw it fit to expel the offending bullies. No way was he letting those horrible students near Nagisa ever again.

It was a horrendous sight, to see a student of the school being so horrible treated and no one to help. Instantly, Gakuho had decided to take the young Nagisa under his wing and taught him how to defend himself-how to read in between lines and decide on the best course of action to take when dealing with people he could not win against physically.

Nagisa was his favourite Gakuho could not deny that fact, even when Gakuho had vowed to not show any favouritism. It was hard not to treat Nagisa differently. Unlike many of his students, Nagisa was, well...different.

And even after so long, Nagisa has hardly changed, remaining kind and friendly to others. Although he was still shy and had a lack of confidence, his eyes glinted a hidden sort of knowledge he didn't had before. He had known of how Nagisa had protected a student from being thrown into the trash bin known as Class-E, and though Gakuho knew he shouldn't had, but he had gave in to Nagisa's pleading and left the Akabane boy in the main building.

Now that Nagisa was interested in that cunning death god, Gakuho could only pray that his favourite student doesn't get himself too involved in the tasteless 'experiment' started by a useless scientist.

End of chapter

*- Kouchou is a title for the Headmaster/Principal of a school.

I would have written more if it wasn't for my need to sleep, but I wanted this up as soon as possible. (;_;) Maybe I'll edit it, but that'll be after a few more chapters are posted.

This is most likely gonna end up as a Koro-senseixNagisa(cause Gakuho is married, and I find it against my morals to make a married man love another person. But the plot might change and Gakuho might just be added into it for the sake of making it a love triangle.) fic, but who knows? It might stay general.

Some characters are OOC, but this is a an Au(If you didn't notice with Koro-sensei being a human, or with Nagisa being a lot older than he should be, now you know.) for a reason.

1st chapter not so much of Koro-sensei-even though he's one of the main characters-, but the upcoming chapters would have more of him(Hopefully).

*Shipping Nagisa and the God of Death is a guilty pleasure of mine.*
