8x188 - REBORN!

Daemon engages Tsuna alone in battle and traps him in an illusion and tricks Tsuna into firing an X-Burner at where Kyoko, Haru, Yuni, I-Pin, and Chrome are. Mukuro quickly takes over Chrome, averts the attack, and disperses the illusion allowing Tsuna to defeat Daemon. Daemon, convinced he is unable to change the Tsuna and his friends, gives up on changing them. Instead, he begins to questions Mukuro and deems him worthy as the Mist Guardian and allows him to pass the trial as he sees Mukuro much more promising than the other guardians. At that moment, Primo appears and declares Tsuna to be worthy to be the Tenth Vongola Boss after observing his every actions and also passes him. The First Generation of the Vongola Family then return their consciousness to the Vongola Rings and so does the remaining Arcobaleno. The next day, Tsuna and his friends gather at the Namimori Shrine where they are then sent back to the future by Spanner.
