Together with the Thunder…!!

Summary
A storm brews. Zetsu realizes that Sasuke has taken advantage of his own fire technique and Itachi's Amaterasu to create perfect conditions for lightning. By controlling the natural lightning, Sasuke gains a devastating and unavoidable technique: Kirin. Itachi is struck and the surrounding area is destroyed. After the clouds dissipate Sasuke believes he has won. Itachi corrects him. Angry that his final attack has failed, Sasuke activates level two of his cursed seal. Itachi assures him that Kirin was a powerful attack, but that he has Susanoo.
