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.
Byakuran parvient à provoquer une réaction du 7³ qui l'isole lui et Tsuna à l'intérieur d'une barrière impénétrable, à l'intérieur de laquelle Uni est à son tour attirée. Byakuran, Tsuna et Uni s'y retrouvent donc seuls sans que personne ne puisse intervenir.
Tsuna e Byakuran portano la fiamma dei loro anelli al massimo e intorno a loro si forma una barriera. Anche il ciucciotto di Uni inizia a brillare e intorno a lei si forma una barriera che la trasporta dove i due si stanno affrontando.
白兰的实力令阿纲完全无法招架，双方不断强化死气之火，进行力与力的对抗。在火焰强度达到极限的时候，两人的戒指忽然共鸣发出响亮的声音，远方优尼身上的奶嘴，也发出相同的声音并释放死气之火。里包恩推测这是天空属性的Tre ne sette在相互呼唤，优尼就这么浮到空中前往白兰与阿纲那里，这究竟是怎么回事？这样下去优尼将有危险。
La batalla entre los jefes Vongola y Millefiore continúa, pero las cosas no se ven bien para Tsuna. La fuerza de los Anillos del Cielo trae a Uni a la zona de combate, creando un campo de fuerza que rodea a los tres e impide el acceso de todos los demás. Tsuna queda inconsciente poco después, sin ser rival para Byakuran. Aun cuando parece no haber esperanza, Tsuna se levanta y es apoyado por la voluntad de la Primera Generación y sus amigos. Su motivación son todos los momentos preciados.
