Because Reborn was the first one to get blasted into the future…

Disclaimer: I don't khr or any of its characters.

Reborn never wants to have children because believe him; two dame-students were more than enough. But to him, his students are his kids, in a very warped twisted way, so he's willing to do anything to make sure they reach their furthest potential, even if it leads to death. So that is why, he is neither surprised nor shocked when he finds out that he has died in the future.

Since he has become an arcobaleno, he knew that his time was ticking away. It only ticked faster when he started to teach Dame-Tsuna to become the best mafia boss in the world. It is already good enough for him that at least he can see dame-Tsuna become the Vongola Decimo before his death.

Until he finds out that in the future, dame-Tsuna has died as well.

For a brief moment, Reborn can't breathe. There is the sinking of his heart as he tries to process the damned news; there is the roaring of blood in his ears as it drains from his face and there is the simple numbness of his body as he is thrown into this mad, mad world.

Reborn has failed.

As a tutor, as Vongola's best hitman, as the strongest arcobaleno…as a father, he has failed completely.

Because he is supposed to have taught dame-Tsuna to become the best mafia boss, the best didn't die so easily, he is supposed to have made sure no harm came to the Vongola Decimo when his guardians weren't there. He is supposed to protect his 'kid' with his dying will even if he had to rise from the grave to do so. Where was he when Vongola and dame-Tsuna needed him the most?

He was dead.

Reborn find it rather ironic, that all this time he was about ready to answer death should it knock…but now, now he wanted his future to be alive more than anything…if his future was alive, dame-Tsuna had a chance. But now, they had this chance…Reborn was going to save dame-Tsuna, without a fail and dame-Tsuna would be the best mafia boss who wouldn't die.

At least, Reborn had planned to do it alone…until dame-Tsuna was shot from the present…into his coffin enclosed future. Reborn very nearly hugs dame-Tsuna…but he restrains, because that would be nothing like 'the demon tutor' he had been so far and a good hitman does not show his emotions. Reborn just waits for things to be explained and he plans. Dame-Tsuna can train in the future, his guardians can grow…they can become stronger and Vongola will be better than ever…but even as Reborn plans, he can't stop the cold darkness of failure from seeping into his soul.

Later that night, when he slips into dame-Tsuna's room, he tells himself that it's because he sleeps better with familiar people…but that night, Reborn doesn't sleep a wink. For every twitch dame-Tsuna makes, every breath he exhales and inhales, Reborn is watching. He never blinks, never once tries to catch a wink of sleep…because he needs to make sure that that steadily beating heart remains beating, thrumming with life.

Reborn has already failed once…never again will there be a repeat.

If he cannot save the future…at the very least, he will save the present.

Question: For my next oneshot, should it be a cracky-angst or a serious-angst?
