Is Hidan still alive? From what I recall, Hidan's head was buried deep inside a hole in the Konoha Forbidden Jungle.

Does it mean that Hidan is still alive after all this year? Is it possible for someone to rescue him and bring him back if he is still alive?
Although it's mostly based on speculation and it isn't really mentioned in the series that that he is definitely alive, when Kakuzu was reincarnated during the Fourth Shinobi World War, he took Hidan's absence as proof that he was still alive (Chapter 530, page 3).
