1 Prologue

It has been 20 years and the people, including mafias all around the globe, was at peace.

After the Vongola Family succeeded on sealing Byakuran's power with the help of the Arcobalenos - seven powerful babies around the world, it has been peaceful.

It had been peaceful.

"Vongola Decimo is dead!" it was written in the headlines of The Mafiosi Lines - a newspaper only distributed to Mafias. It includes the bounties for some bounty hunters in a mafia and some for the economic growth of each mafia.

After seeing the headlines of the said newspaper, the seven guardians of Vongola was in a shock.

"B-boss is dead?" Gokudera said with his unbelieving eyes.

Among the guardians, Gokudera with his loyalty towards Vongola Decimo - Tsunayoshi Sawada, did not believe about his death.

The six guardians were summoned to the headquarters of Vongola Famiglia in Italy by Reborn - the home tutor who looked after Vongola Decimo. With that being known to the guardians, Reborn is yet to appear.

"How can we tell this to her?" Ryohei mutters to himself.

Ryohei is worried about what to tell to Tsuna's family, most of all, his wife. Having this news known to his family, he knew that it will only bring grief to them.

The room inside the HQ was quite.

It was quite till somebody knocked on the door.

"Please, come in." Takeshi opened the door.

On the other side of the door, there appears a man in his black suit and wearing a top hat. He was far different for how he was before but all of the six guardians knew it was him.

"Reborn." all of the six guardians said in different tunes.

What greeted Reborn is the grieving auras of the seven guardians.

Hayato Gokudera, the wielder of the Storm Ring; Takeshi Yamamoto, the wielder of the Rain Ring; Ryohei Sasagawa, the wielder of the Sun Ring; Lambo, the wielder of Lightning Ring; Kyoya Hibari, the wielder of Cloud Ring; and Chrome Dokuro, the wielder of Mist Ring and the one which Mukuro Rokudo - the guardian of the Mist, possesses.

"Reborn, is it true? Is the boss already dead? Tell me, it is just fake news, right?" Gokudera immediately approached the newly arrived Legendary Arcobaleno who wield the Yellow Pacifier - Reborn.

After hearing the immediate question of the storm guardian, Reborn wears a stern look at his face.

"Yes, it is true. Tsunayoshi Sawada - the Vongola Decimo had died right beside me."

After hearing the answer of Reborn, all six of them were inaudibly shocked. They heard that Tsuna is really dead, but what shocked them the most is that Tsuna died beside Reborn.

"W-what?! How did he die?! How can he die when you are right beside him?" Gokudera continues to ask questions rapidly to Reborn which proves his disbelief. He cannot accept the fact that Vongola Decimo has died.

"Honestly, I do not know myself how he died. He just fell on his knees and then the next thing I knew, he has no pulse already and was not breathing." Reborn answers with a doubt in his mind.

He doubted the way Tsuna died. He knows it well that Tsuna is a loser by nature but he also knows that he won't go down that easily.

After answering Gokudera's question, he pulled out a brown envelope in his suit's pocket and hand it over to the six guardians. It contains a letter from Tsunayoshi Sawada and looks like it was recently made.

"Tsuna asked me to hand it over to you. He asked to keep this thing a secret for us and I will clear all of the rumors surrounding the death of Vongola Decimo. Nobody has to know about the death of Tsuna or else, the future will be in big trouble." Reborn ordered them.

"But it was already released on the press, Reborn." Kyoya finally talked after being silently standing in a corner.

"I have my connections to clear those rumors," Reborn answered him briefly.

All of the guardians silently read the letter for them by Tsuna. Reborn was taking his time to wait for the guardians to finish what they are reading.

"Is this real?" Chrome asked Reborn as soon as she finished reading hers.

"As you might know, I have to go somewhere to do my work as a home tutor. You guys might already know your tasks by now as per ordered by Tsuna." Reborn cleared.

The six guardians nod in agreement as soon as Reborn finished.

"Well, I shall take my leave now. I have some cleaning to do after all." Reborn left the room which left the guardians in a silence.

Just outside the room, Reborn opened his letter.

"Reborn,

If you have received this letter through your mail with the letters for the six guardians, you should do just as what this letter says for you.

First, you have to hand over the guardians' letter and make sure they follow what's in it.

Second, clean after the rumors about my death was being spread.

and Third, you will need to go at southeast Asia ten years after my death and tutor my grandson which my daughter will bear ten years in the future. I have traveled accidentally through time and saw that when these events were not met, a dark future is ahead of us. You need to make this boy be a good one and shall deserve the name of the Vongola.

I am entrusting you with this task Reborn and shape him up to be a better Vongol boss than I ever was.

Tsuna."

"Ten years in the future, huh?" Reborn uttered to himself.
