Reborn

Tsuna receives the Vongola Box from Irie. However, Irie shockingly tells him that in order to draw out the true power of the Vongola Rings and open the Vongola Box, the Seven Arcobaleno Seals are needed.

Back in the past, the Arcobaleno are heading to Namimori to present Tsuna with their trials. Meanwhile, in the future, Irie is giving Tsuna and his friends instructions on how to return to the past.

One day has passed since Tsuna and his friends had returned to the past and they still have yet to receive a trial. However, during recess they are suddenly attacked on the roof!

Colonnello shows off his overwhelming strength. Barely able to catch his breath dodging the attacks, Tsuna can’t use his X Burner.

Concern for Chrome brings Tsuna to Kokuyo Health Land. Hibari and Mukuro suddenly show up. The longstanding grudge between the two comes to a boil as soon as their eyes meet and they begin to fight!

A fog-draped morning, Tsuna is called out to Nami Middle by a mysterious phone call. On the way there, he runs into Yamamoto, Ryohei, and Gokudera, who received same kind of mysterious phone call.

Tsuna receives a letter. Inside the letter, there is a photo of someone wearing sunglasses and a note that reads “Try and catch me.” Reborn says that the person in the photo is I-Pin’s master, Fon.

There are three remaining Arcobaleno Trials, one of which is the sky Arcobaleno. Tsuna resembles the Arcobaleno and thus takes an interest in them, but Reborn tells him that the sky Arcobaleno has been missing for quite a while.

At last, the day of Reborn’s trial rolls around. When Tsuna and the others arrive at the assigned destination, Reborn tells everyone they are to fight him to the death.

Tsuna and his friends are told that they did not pass Reborn’s trial. Tsuna and his friends are upset, but they somehow muster up the energy to ask Reborn for a second shot.

Verde attacks Tsuna and his friends with a weapon of his own invention. Verde’s intention was to attack Tsuna and his friends while they were weak so that he could steal the Vongola Ring.

Verde takes Reborn and the Arcobaleno hostage and demands Tsuna to hand over the Vongola Ring. Tsuna and his friends refuse to hand it over, and they head for the unfinished box weapon in order to save Reborn and the Arcobaleno.

It turns out that the Verde they were fighting this whole time was not actually Verde, but a robot! The guardians are overcome with fear. Time is running out before they have to return to the future.
