"Desired Pain…!!" (望んだ痛み…!!, Nozonda itami…!!) is chapter 326 of the original Naruto manga.
Summary
Kakuzu sews Hidan's head back onto his body. With Shikamaru exhausted, Asuma tries to escape with his team, but Kakuzu blocks their exit. Izumo and Kotetsu attack him while Asuma goes after Hidan, intending to stop him from restoring their link. Hidan strikes with his Triple-Bladed Scythe. Asuma dodges and it strikes Hidan, but he discovers too late that Hidan has returned to the Jashin symbol that causes them to share damage. Asuma doubles over from the pain the scythe has done to Hidan while Hidan, despite Shikamaru's attempts to stop him, stabs himself in the heart.
