Byakuran coaxes Tsuna into igniting his ring causing a 7^3 reaction which creates an impenetrable barrier whilst drawing Yuni into the same barrier. Byakuran crushes Tsuna into unconsciousness. He then discovers Yuni was attempting to revive the Arcobaleno to restore the balance of the 7^3 and to assist in the defeat of Byakuran. Reborn converses with Tsuna and is able to awaken him by disclosing that Yuni is using her life force to revive the Arcobaleno and will die when the rite is complete. Byakuran mocks Tsuna about his unlucky life and attempts to kill him once more but is saved by Lancia's ring. Tsuna realizes his friends have been with him throughout all the bad times and regains the resolve to fight resulting in Vongola Primo and his guardians to appear from their respective rings.
