"Intemperance," a story from the secret journals of Doctor John H. Watson, intimate friend and long-time companion of the infamous Sherlock Holmes: A most curious and instructive report of the great man's improbable fecundation, gestation, and parturition.

Tsuna doesn't know how he dies for good, only that he still has regrets when he does. When he wakes up, he's in the body of Sawada Nana, mother of a 2 year old Tsuna, and those regrets become tenfold. He's drowning in the implications, when an Arcobaleno appears on his doorstep, and the future becomes infinite possibility.

It was only supposed to be a game. A fun way to pass the time. Maybe even make friends. How was Tsuna supposed to know Jumanji had a mind of its own, or that 'survival game' was very literal?

Later, he will say it was a calculated choice, that he looked at the odds and looked at the clones and decided that better the Jedi he didn't know than the Sith he did. This is, as it happens, a bare faced lie. (or: A Sith Lord realises, abruptly and rather late, that war means casualties, and decides that the great Jedi genocide plan can go fuck itself.)
