The Judgment

is episode 78 of the Naruto: Shippūden anime.

Synopsis
Asuma's Fire Release technique strikes Hidan, but, to his team's surprise, Asuma gets burnt as well. Hidan then reveals his ability to link his body to his opponent's after ingesting their blood. Asuma rushes at Hidan, but collapses after Hidan stabs himself in the leg, thereby injuring Asuma. Shikamaru realises Hidan needs to be in the circle for his curse ritual to take effect, and so, uses his Shadow Imitation Technique to force Hidan to step out of it. As he does so, Asuma gets to strike a finishing blow on Hidan. As Hidan screams, Asuma decapitates Hidan with his chakra knife.
