Pain.

That's the last thing that he felt before he was consumed by darkness.

He felt empty and lonely in the void.

Nothing to see, nothing to feel, nothing to hear.

Just nothing.

His only companion was his mind.

Until everything came back again.

Until he opened up his eyes again.

Tsuna didn't remember lying on a mattress. The last thing he laid on was the floor. The beeping machine that he already used to hear. The numb feeling in his body that he is already familiar with.

He tried to move his finger slowly until he could move his hands. When he was sure he could sit, he moved and sat.

Tsuna looked at his surroundings. Just like he had guessed it, he was at the hospital.

Does someone save him? Is it his guardians? But he was sure he was dead.

So how?

The cluttered sound of a falling object brings back his attention to his surroundings only to see the shock on the nurse's face.

"DOCTOR!!!! " She screamed and left to find the doctor. Leaving Tsuna bewildered and alone on the bed.

Nagisa felt a bit bitter about the exam result. Of course,he does better than before. However, the bitterness is still lingering.

Since Koro-sensei had high expectations of them.

Nagisa's step faltered upon seeing a man standing in front of the entrance to the 3-E school building. The man wore a simple white shirt and seemed lost. "Excuse me, can I help you? " Nagisa asked the stranger.

The stranger looks at him with delight.

"Oh my, thank you!You see, I was wondering, do you know where the class 3-E is? They told me to go here but I have lost."

Class 3-E? Why would he go there? Wait... Is this person in any way connected to the assassination? Maybe he is another hitman...?

The stranger smiled at Nagisa while waiting for his response, as Nagisa stared back in contemplation.

But... His smile seems too nice for that...

"I'm a 3-E student, I could lead you there."

Hearing Nagisa's answer, the stranger smiled in delight. " Thank you for your offer!!! "

Nagisa couldn't help but smile as he saw the stranger's beaming smile.

Sincerely, Tsuna was confused. To think that he woke up in a completely different world.

Well, not like an Isekai world but still different than what he knows.

For instance, he was in a coma for 3 months.

The doctor was sure that he would not make it. Yet, here he is. It's not like the doctor was wrong. He indeed died.

The other him.

If it were not for Byakuran, he would definitely think that his experience as the tenth boss of Vongola was just a make-up life.

And all of his friends would be just an illusion. A fever dream that he wishes is real.

But they are real. Even if they live in another timeline,another universe.

Even if Tsuna would never see them again. They are still his precious comrades that he was glad to meet.

That knowledge is enough to ease his heart.

The second reason is that he is not the only candidate for the throne in this world, meaning that Nono's sons are still alive.

So, he concluded that there is no reason for the no-good Tsuna to be the heir. Since he is not the heir, he lives an ordinary life and somehow becomes a teacher.

The knowledge for him that he had become a teacher is important because...

"Do you understand what we just informed you? "

It appears that his job has ties with the government. Also, It's absurd to think that his job is being taken by an insane, earth-destroying octopus with mach speed.

Now he is jobless.

" I understand that. Don't worry about it. " He dismissed them. For now, he should worried about money. He didn't know this world Tsuna's financial position. Does he have enough money to pay for the medical bill?

As Tsuna contemplates his next move, Karasuma chooses to speak. " Truthfully, you should be the one teaching them. But because of this circumstance, you lose your right and opportunity as an educator."

Tsuna gazed fixedly at the envelope that Karasuma held in his hand. "We would like to offer you a teaching position for class 3E as compensation."

Oh, it seems that luck finally came rolling to him. For everything that he had been through, he really needed a breather.

and that's how he became a counsellor despite having no experience.

The two keep on walking silently. Tsuna didn't know what his future student was thinking but he couldn't help but feel at peace. To be able to walk in nature like this reminds him of his old headquarters. A castle surrounded by nature.

He just hoped it still standing.

" Mister, we already arrived," Nagisa informed him. His voice is a sign for Tsuna to start to focus on his new job.

This person didn't talk at all in their journey to the old building. In fact, he seems to be at peace. It makes Nagisa wonder if he could feel the same when he walks to the school.

When they arrived, he told the mister. The mister smiled and thanked him before walking to the door. Right before he went inside, he stopped and looked at Nagisa.

" By the way, Call me sensei next time." He winked and left. Leaving Nagisa gaping alone.

" This is Sawada Tsunayoshi. From today onward, he will be your counselling teacher."

The said teacher was blatantly staring at Koro-sensei. The students began to whisper to each other.

" A new teacher..."

"Is he an assasin?"

"You mean like Bitch-sensei?"

"But he doesn't look like one..."

Tsuna could hear all of that but chose to ignore it. Right now, the octopus teacher looks more interesting. If Gokudera's here, he would flip. Literally.

The stare that Tsuna gave makes Koro-sensei sweat.

"Are you an alien?"

Koro-sensei sweatdrop. "No..."

Ehhh... A bummer. Tsuna couldn't help but lose interest for a bit and the octopus could feel it too.

"I... I'm fast!!!"

So do Tsuna and Hibari and other people.

It seems that Tsuna's disappointment was showing on his face making Koro-sensei panicked for a bit. He immediately flew outside and came back with a gelato from Italy.

" See! See! I bought a gelato from Italy!" He gave it to Tsuna.

"Oh! Thank you! But you could just buy it in Japan, right?"

And that statement made Koro-sensei speechless. Honestly, the situation was kinda absurd. They had never seen Koro-sensei act goody-two-shoes with someone who was not his superior. Sawada-sensei is not even a hot chick like Bitch-sensei. So why did he act like that?

And Karma was willing to ask it. " Sawada-sensei! Do you have dirt on the octopus?"

Thank goodness for that. The other didn't have a thick skin like him.

Sawada-sensei seem to be contemplating about it. Even he looks lost.

"You... You don't remember...?"

'Remember...? ' He thought.

Scratching his head, Tsuna looks bashful. "Ah... Sorry, but it seems that I lost my memory due to the accident..."

The other may not know the story between those two but surely, Koro-sensei seemed to be feeling guilty about it.

"Whatever happened in the past, let it stay there. Right now, we are just colleagues. I'm new in this industry so please take care of me, Koro-sensei!" Tsuna gave a bright smile to him.

Whatever history in the past is between this world Tsuna and Koro-sensei. It has nothing to do with him.

'So, please don't use me to pay for your mistake. I didn't deserve it.' he thought.

Koro-sensei doesn't seem to agree with it but... " If you said so, welcome to the class 3E! Sawada-sensei!"

The welcome that he received felt bitter for some reason, yet he couldn't help but smile.

" Please take care of me, everyone!"

And that's the first time the class 3E met with the former mafia boss. Not like they know about it.
