25-year-old Lambo has just been summoned. Levi A Than uses his Levi Volta for the second time, but 25-year-old Lambo absorbs it with his perfected Elettrico Cuoio and turns it into Elettrico Reverse. 25-year-old Lambo suddenly notices the pair of horns child Lambo left behind and uses one to block a parabola Levi A Than threw at him. 25-year-old Lambo shows them what was under the paint that was knocked off by the parabola: "Dumb cow", revealing that the horns Adult Lambo got from Iemitsu actually belonged to 25-year-old Lambo. Lambo promptly takes out his backup horns, equips his real horns, and activates his Thunder Set. Reborn comments that the user would need to be within close range of the opponent to use Elettrico Cornata, but 25-year-old Lambo releases the lightning as a blast instead. The blast successfully strikes Levi A Than, doing a great amount of damage. Before 25-year-old Lambo could strike the final blow, he is suddenly replaced by child Lambo. Enraged, Levi A Than stomps on Lambo several times and smashes him with a parabola. As Levi A Than is about to kill Lambo, he jumps out of the way to avoid the falling lightning rods of the Elettrico Circuit. Tsuna, the cause of the fall of the lightning rods, states that "If I have to watch my precious comrades die with my own eyes, I wouldn't be able to atone for it, no matter how many times I died."
