Chapter 1

Chirp! Chirp!

A sound that he had missed to hear. When was the last time he heard the birds chirping happily? He can't remember. What he remembers was the sound of gunshot everywhere.


Unconsciously, his hand retracted from under the duvet and slam on the poor clock. Pulling the duvet from his head, he opens one eye. He grimaced as he touched his heart where he was shot at. He watched the ceiling for two minutes as the gears on his brain start functioning. The first word he said:

"Where the heck am I?"

He sits on the bed, clutching his head that's hurting like hell. One question lingers, unanswered.

"Why am I alive?"

Yes, why is he alive? He still remembers what had happen. A war between Vongola and San Lorenzo, the death of his father, Sawada Iemitsu and his guardians and many more. And finally, him. He was the last person who had protected him, the person who had loved him. Reborn, jis tutor and his lover was the last one who had died in front of him.

All of them had died. Died while protecting the Decimo. Him.

"Heh, even though I'm the Decimo, I'm the one who being protected." He chuckled bitterly. Images of his precious family, guardians and tutor played in front of him. The smiles, laughter, fighting; he missed all of it.

Tsuna watched the rising sun.

A new day and a new world.

A sigh. He let his eyes drift around the room. It was the same room he had lives since his younger days. A photo frame on the desk catches his attention. He walks towards it and grab the frame. It was him with his mother. He gave a longing smile, brushing through the frame. His mother had known about him being in the Mafia – not before she gave hell towards his husband after knowing it.

After a while, he sees something on the desk, shining. It was a ring. A ring that he had wears every time and every second. It was the ring that Reborn had given him, the same day he had confess to him. Tsuna of course happy, so happy that he could die of happiness.

Just remembering about it, is enough to make the dam he had hold to broke. He clutched the ring like it was his life line, sobbing while repeating his lover name.

He wants him.

After an hours of breaking down, he finally calm down. Dame-Tsuna, the Boss shouldn't show weakness towards anybody. He remembers what Reborn had said. Well, you always had place if you want to cry, with me that is. His smiles grew fonder. Reborn had always been the tease one and he always fell helplessly with it. After another set of exhaling and inhaling, he tried to sort of his mind for now.

After that, he take a look on his desk, there's computer and laptop on the desk, a sheets, and USB that he rarely saw. A 'Ping!' sound come from the computer made him diverted his eyes towards it.

New mail just comes.

He stared at it before deciding to open it.

From: Unknown
To: HackerCielo27
Subject: None

Thank you for giving us the information. As promise, we have transfer the pay to your account. Until next time.

Tsuna look at the mail for a minute as the thought of him being a hacker in this world invaded his mind. Sighing, he closed the mail before opening the folder from the computer one by one. Each folder consists of information that higher-ups couldn't get in. He frowned when there is picture attached to each of files he had open. They are various kind of crime.

Smuggles, thief, drug-dealer, human-trafficking, parent's abuse, etc. This is not something he likes to see. But, as he was the Vongolo Decimo in his previous world, he had seen all kind of crime and he had stopped almost all of it. He open more and more folder and grew disgust at each of the information.

But, there is one folder that really catches his attention. It was about the moon being destroyed by some kind of Yellow Octopus creature. Is that even possible? Well, if he thinks more of it, what kind of people had fire on their head but didn't get burn by it? So, he just thinks of the possibility of some yellow octopus creature exist is possible.

It's already afternoon when he stopped looking at the computer. The angry growls on his stomach are the sign for him to stop and just eat to ease his stomach. When he go towards the kitchen, he can felt how empty the house is. In his previous world, hei old home in Namimori would be already full with bickering from the kids, Lambo, I-Pin and Fuuta, with Bianchi profuse his love towards Reborn – of course Reborn ignore it. And when they had move to Vongola mansion in Italy, the bickering, fighting, laughing and crying had been their daily life.

Tsuna let out a smile as he cooked some simple Omelet for him.

That evening, after he had his brunch, something happen.

The memories of this world Sawada Tsunayoshi suddenly attack him. Too many information and too many memories had come like a machine gun being shot at his head. Can't take any more of it, he collapsed on the dining room. When he wakes up, the sun already set at the horizon. It's been seven hours since he faint.

He groans.

He didn't know that this world Sawada Tsunayoshi was a loner despite being a hacker and assassin. This world Sawada Nana was admitted to the hospital due to stress, anorexia and depression. It was months ago he visit his mom. He should apologize after this, even though it's not his fault at all.

His circle of friend is limited or should we say there's only one person. Tsuna was of course surprised by the information he get, his friend was – is – Karasuma Tadaomi from the Ministry of Defense. At first, he thought, what kind of friend he is if this Karasuma person is from the Ministry of Defense? Another puzzle that made his head wants to explode right there and right now.

As night soon comes, he's tired already. Wake up in a parallel world, being a hacker an assassin, memories of this world Sawada Tsunayoshi and information had finally get the better of him. He just wants to rest now. Had good night sleep.

When suddenly his phone ringing.

He cursed at whoever had invaded his sleeping time. Answering it with a gruffer voice.

"It looks like I'm interrupting your sleep, Sawada?"

"Hell yes you are…"

"Well, I'll make it short then."

Tsuna wait for this mission. How he knows it's a mission? Because it's that person who had called him.

"What mission this time Karasuma?"

"Become a teacher at Kunugigaoka Junior High School."

That wake him up.
