SEASON 1
The story will gonna take place when Tsuna is reunited by her childhood friend Mato Kuroi.
It'll have Tsuna having killed Byakuran, the leader of the Millefiore family from the future, who had been trying to retrieve Tsuna's beloved Yuni.
The series would be more "darker" and a "serious" tone and it's still gonna have a comedic tone. But, it'll deeply be a soft reboot to the original and will retell the events of Reborn!.
It will reintroduced Kensuke Mochida, the captain of the Namimori Middle Kendo Club and the first antagonist of Katekyo Hitman Reborn, after his initial confrontation with Tsuna in the first place. Also, he didn't appear in any episodes but once last scene when Mochida was injured at a hospital during the Kokuyo gang incident (which was unconfirmed if Mochida's hair grew or had a wig).
Kensuke Mochida, Nezu Dohachiro, Osamu Kaneda will return ever since they only appear in one season of Katekyo Hitman Reborn!.
The season would focused on the mysteries of the future that Tsuna and the gang are up against and dark secrets of the series. Then, it'll focus on Mochida's family tree who had ties to the mirror masked figure, the Reign.
