Hidan can't be killed, but Shikamaru DOES amputate his head and bury it REALLY deep into the ground somewhere in his family's deer forest place where he won't be able to attach his head back to his body.But I make it sound like a dull adventure, but he uses a clever strategy, as always. The episodes for those manga chapters are coming up in a few weeks.
