Although Kakuzu avoids being hit by the mace, he ends up being stuck by the Starch Syrup. Using his special ability, he unwinds his hands and uses them to keep Izumo and Kotetsu in a death grip. Hidan, now restored, draws his Jashin circle and attempts to finish off Asuma. Asuma, however, attacks back with his chakra blades, but misses; Hidan, however, manages to slice Asuma with his Retractable Spear. Hidan then pulls his Triple-Bladed Scythe and attempts to impale Asuma from behind, but misses when Shikamaru manages to warn Asuma in time. The scythe ends up embedding itself within Hidan, but as Hidan had ingested Asuma's blood and was in his Jashin circle, Asuma is wounded too. Wanting to finish Asuma off, Hidan takes his Retractable Spear and stabs himself in the heart, mortally wounding Asuma.
Back in Konoha, Kurenai notices a flower drop and split in two, and immediately senses that it is related to Asuma.
When Hidan's decapitated body was shown during a panoramic shot of the battlefield, he had his right side of his cloak, even though it was destroyed during a previous episode by Asuma's Fire Release technique.
Also, when Kakuzu strangled Kotetsu and Izumo, his ring wasn't present on his left middle finger.
