As the fight continues, Xanxus tries to break the ice and release his flames. However, Tsuna prevents him and begins to freeze Xanxus' entire body. As Xanxus becomes frozen, he reveals that this scenario is similar to when the 9th Vongola froze him. Squalo finally reveals the whole story of what happened 8 years ago during the "Crib Incident" and how the Varia attacked Vongola headquarters but failed due to the freezing of Xanxus. Meanwhile, Ryohei is shown freeing Gokudera, Yamamoto and Chrome from Mammon and Bel's trap. However, Mammon was able to get all the guardian rings and is seen at the end hovering over the frozen Xanxus saying that all the rings will reawaken Xanxus.\

With no escape routes available, and Mukuro Rokudo being in a weakened state, Mukuro explains to Chrome Dukuro that it is up to her to win the fight. Drawing power from both her trust in Mukuro and the Vongola Ring, Chrome's illusions become far more effective, to where even Glo can't tell whether or not they are real. The fight soon concludes in a victory for Chrome, and the future Ryohei is introduced at the very end of the episode.

The Shark and Rain collide on this exciting conclusion.

Gokudera talks about his Sistema C.A.I. and explains how he discovered its use. Hibari continues his way into the subway and uses his box weapon to trap the Millefiore members on the other side.

The battle for the Ring of Rain commences. Yamamoto shows off his new Shigure Souen Style and it looks like victory is assured. But slowly Squalo gains the upper hand as none of Yamamoto's attacks are hitting. He then reveals that he can read through all of Yamamoto's moves.

Yuni explains that like the Mare ring's ability to allow its user to travel through parallel worlds, the Vongola rings allow the past generation to communicate with their current successors. Vongola Primo converses with Tsuna, revealing the rings had a seal on them, allowing them to be split in half for the Vongola Tournament and their current forms only possess powers equal to the Mare ring. Primo releases the seal causing the Vongola Rings to change forms and disappears. Tsuna continues his battle with Byakuran, overwhelming him completely. As Yuni nearly completes the rite, Gamma manages to infiltrate the barrier and embraces her; exclaiming he will die with her. As the rite completes, their bodies disappear leaving behind the Arcobaleno pacifiers. Tsuna and Byakuran's battle climax with Byakuran perishing from Tsuna's X-Burner.

As Gamma is about to deliver the finishing blow to Gokudera, the future Hibari arrives to save him. Hibari manages to defeat Gamma with his hedgehog box animal and tonfas, both which are enchanted with the cloud flames.

After the fight, Xanxus is released with the power of the 7 rings which he was originally released by from the 9th. There is a short flashback of his life, and a secret is revealed: Xanxus is not actually the 9th's blood son, and so, the rings rejected him. At the end of this, an elite group of Varia arrives.

Dino's unsuspected guest is revealed to be Squalo, who Dino saved instead of Yamamoto and brings to see the sky match. Yamamoto along with Gokudera propose a trade between Mammon and Bel, which turns out to be a well played trick but is countered by Mammon's illusions which binds both Yamamoto and Gokudera, Gokudera of which drops the remaining rings. Tsuna and Xanxus have a struggle where Xanxus powers up, which seems to turn the tide of the battle. Tsuna and Xanxus then charge at each other which results in a huge explosion.

However, Gokudera figures out the secret to his trick, and unveils his new technique: Rocket Bombs. However, once Gokudera finally strikes Belphegor, he starts to act strangely.

With the new Rebuke Bullet, Tsuna has reached a new level of power, but it still may not be possible to defeat Mukuro, who still has not revealed his strongest form.

Tsuna prepares to use the fruit of his hard training: the Zero Point Breakthrough. Xanxus, however, recognizes this attack and proceeds in a hectic beat down. Reborn reveals that maybe using it to attack won't beat Xanxus anyway.

After the Cloud ring conflict, Xanxus tries retrieve Gola Mosca. After Hibari halts his attempt at retrieval, Mosca goes on a rampage, shooting wildly at everyone friend and foe.
