REBORN! - Season 5 Episode 149

Reborn tells Tsuna and his guardians to assemble at Namimori Island for the next trial. When everyone reaches Namimori Island, the trial is revealed to be a battle of Tsuna's family against Reborn. Reborn knocks Tsuna unconscious and battles against Tsuna's guardians. While watching the trial, Lal Mirch recalls what had happened when the chosen seven to protect the Arcobaleno pacifiers met for the first time, and reveals that Reborn was the strongest of them. Tsuna regains consciousness after the defeat of his guardians and engages Reborn in battle. During the battle, Reborn reminisces on the day he became an Arcobaleno. Tsuna gains the advantage over Reborn, hesitates to use the X-Burner and is defeated. Reborn then announces Tsuna has failed his trial.
