There are two Sawada-Twins in this world,
  - Sawada Yuki (five-year-old younger brother) has been missing ever since Estrano abducted the experiment after 11 years. 
[Vongola's succession candidate for the tenth throne.]
- Sawada Tsunayoshi (seven year old brother) is hitman, hacker. Missing three years before his younger brother, the teenager was with Rokudo and fled to China. At the age of 16, he formed a group
| RIVOLUZIONE |.

**********************************

Not long before the guards except Hibari, Rokudo, Reborn (former teammates) erased the memory of moving souls to the parallel world according to the plans of Gesso,
Giglio Nero,
Sinclair,
Key (Tsunayoshi 19),
Cavallone,
Kozato,
Varia (Xanxus in this world are older, separated from Vongola),
Hibari (Kyoshi's third great-grandfather (21) heard the information from afar calmly accepted),
Rokudo (father (19) Mukuro's (6) grinning, he and Tsuna went to the same school)

-They all finally agreed to this plan.

**********************************

The brown-haired man glanced outside for a moment, looking through the closed window with the cracked curtain halfway through. It was enough to let light in, but dark enough for him to rest easily.

"Hey, I have a question for both of you."
With the puzzled expression he received, he continued, "If I tell you both to join a group, will you do so? Even if I 'don't' plan to join the said group?"

The two security guards exchanged glances, confused at the question, with Hayato being the first to speak up. "What do you mean, Boss? You mean Vongola? And we don't really want to join anything without you."
The brunet shook his head, "No, I will no longer join the Vongola. I am no longer considered an heir because Yuki, my younger brother, has reappeared to take over. That's why Varia suddenly withdrew. Find him." Leaning back in his chair, he sighed again as he looked up at the office ceiling. "Because both of them received half of the Vongola Rings noticeably, everyone is free to do whatever they want. You can return to your normal life or you can both join Vongola as Yuki's guardian."

"Absolutely not!" Hayato shouted loudly enough to make Takeshi beside him dance to the volume, and stepped forward with his fists clenched into fists.

"You are MY BOSS! The only man I will follow, nobody else, because all I have to do is serve you!"

Takeshi took that time to add, "That's right Key, we want to move on and stand by you because we are friends."

The steadfast gaze of the swordsman was pinned to the brown-haired man.

"Just because you're not going to be a boss without changing anything about how we feel about you, Key." He nudged his sheathed sword to the side of his shoulder for lighter weight. "And we will forever be with ou everywhere."

"Really?" Tsuna looked at the two of them still nodding their stubborn eyes determinedly hoping to look at him.
Tsuna sighed, "Although we have " good memories ", I don't want you to get involved, sorry, I have no choice but to do this." Tsuna snapped his fingers, both of them looking at Tsuna with weird eyes.

"What it mean you say, Key?" Takeshi was the first one to speak, before he could get close to both of them suddenly kneeling and hugging their heads; "Ring Ring" sound kept ringing in their heads. Takeshi held up one hand and covered his ears with the other "K-Key.... ", Hayato trembled and looked up at Tsuna. "B-Boss..... ".

A thrust thrust them both into the black hole.

**********************************

"Plan?" The other asked. Tsuna smirked sadly at the two people who just disappeared. He looked at Tsuna's face like a metaphor of success, he said:

"It went smoothly. The two of them?"

The last sentence, as he wanted, he answered. He replied. "Both have passed through."

"Good. Hope everything goes as Planned."

Reborn stood beside the wall and watched as the two men pulled down the brim.
