The Guardians have collectively betrayed us!

The battle for the rings had just begun when Tsuna, from ten years in the future, suddenly arrived from the future. It turned out that the future world had undergone a massive upheaval, and all of Tsuna's guardians had betrayed him.

To free his companions from their shackles and confront the enemies of the future world, Tsuna decides to recruit Xanxus and Byakuran from this era to his side. Unexpectedly, Tsuna awakens a treasure chest system. By following the system's instructions and arriving at designated locations on time, he can open treasure chests and receive rewards.
