Universe In Flames

Prologue - Murphy's Law

The universe was on the verge of falling apart.

Ever since both Kawahira and Yuni vanished, the remaining holders of the Tri-ni-sette were no longer able to rebalance the flow of power needed to maintain the universe.

"Tsuna," Shouichi paused, peering worriedly at his boss over the top of his spectacles. "Are you certain that you want to go through with this? If it fails..." his voice drifted off.

Smiling wryly, Tsuna couldn't help but rub his palm over his tired eyes. It has been days - maybe even weeks since he had a proper sleep. "If it fails, at least we have tried," he paused, his mind flashing through the events which happened over the past month. "It is not as if we have any more to lose. Not after what happened to Lambo..."

No one expected that to happen and it took everyone by surprise to say the least.

It started off as a regular day - as regular as it could have been by Vongola's standards, and no one thought much about it when Lambo vanished in a puff of smoke. With the way his younger self used the bazooka every hour, the puff of smoke was a common occurrence whenever Lambo was in the room.

But when the younger Lambo failed to appear from the smoke cloud, a silver of worry crept into his heart. After 5 minutes, the worry only heightened when their Lambo never returned.

It has been 6 months since then.

Months of investigation and research only brought about the most worrying of results.

Kawahira and Yuni's disappearance had a greater than expected impact.

Especially since the Sky Pacifier was never found.

A month ago, his team of scientists presented to him their findings. While reading through the binder of testing results and theories, his eyes caught the final conclusion which the team agreed on.

Universe Entropy.

In simpler terms, the universe itself was disintegrating and Lambo disappearance was merely a side-effect due to the underlying problem.

The Arcobeleno - when Tsuna reached out to Reborn for help, were also experiencing a rapid decline in terms of flame output and an increased aging. In the past 6 months, Tsuna estimated that the group have aged by at least a decade.

At this point, the machine in front of him was the only possible solution.

Powered by both the Mare and Vongola rings, Shouichi and his team created this device to send the holders of the rings back to a point in time where they would be able to prevent all of this from happening.

Vongola rings are needed to push the participants back through the generations.

Mare rings to allow the device to lock on the correct timeline.

"When will it be ready?"

Shouichi moved over to the console screen and tapped on the keyboard a couple of times before replying, "it should be ready by the end of the week. There is a couple of calculations which I would like to confirm before proceeding."

"Thank you," a tiny smile graced his face, Tsuna stood up and made his way towards the door. "I will be in the main wing, please let me know if anything comes up."

-------

"Tsuunaa~" a chirpy voice sounded right next to his ear, "are you ready?"

Side eyeing the person who tormented him for most of his teenage years, Tsuna resisted the urge to sigh. "There isn't any other option, is there?"

"It has only been a week, but Reborn's condition has already detoriated to the point where he's nearly bedridden." He clenched his fist as the image of his mentor came to mind.
