Xanxus is eight years old and desperate to find something more than a future in the slums. When he comes across a man with broken eyes and a mastery of orange flames, he thinks he’s found it.

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.

When you have access to the future, you'd be a fool not to use it when it comes to matters of great importance. And within the mafia, nothing is more important than Inheritance. Or, Lambo discovers there's a reason the Bovino shouldn't read the Epilogue first.
