God's Judgement!! (神の裁き!!, Kami no sabaki!!) is chapter 323 of the Naruto manga.
Izumo and Kotetsu rhetorically ask if Hidan is immortal, which he confirms. Asuma had intended to kill Hidan and capture his partner, but given this development decides to switch the fates of the Akatsuki members. Since Hidan is captured by Shikamaru's shadow Asuma goes looking for Kakuzu, but finds Kakuzu attacking Shikamaru in order to release Hidan. The Konoha ninja regroup while Hidan, freed, draws a design on the ground with some of his blood. Asuma engages him in battle while Shikamaru observes and Kakuzu refuses to participate. Hidan injures Asuma with his Triple-Bladed Scythe and, after licking some of Asuma's blood off the scythe, transforms.
