Naruto Shippuuden Unfulfilled Scream Season 4 Episode 8 - fanaru
Hidan's immortality enables him to stay alive even with his head cut off, although he cannot move his body. Kakuzu sews Hidan's head back on with threads that sprout from his body. Izumo and Kotetsu try to attack Kakuzu, but he manages to grab them both by using his body threads, restraining them and suffocating them as well. Hidan, now able to move again, returns to the circle and stabs himself with the blades of his scythe; he finishes it off by stabbing himself in the chest with another spike, fatally wounding Asuma.
