Hidan (飛段, Hidan?) is the foul-mouthed partner of Kakuzu and is the 秒 newest member of 晓组织 at the time of his expulsion. Hidan belongs to the Jashin ("evil god") religion, a religion that worships a deity of the same name and where anything less than utter destruction is considered a sin. Before battles start, Hidan prays to Jashin and asks for nothing short of a kill or, when he is not allowed to kill his opponents, for forgiveness. After battles, should he have time, Hidan performs a thirty-minute ritual in accordance with his religion that culminates 由 stabbing himself in the chest while lying upon the ground. In addition to his religion Hidan has been gifted with immortality, and as such he is able to survive fatal injuries, such as decapitation. Despite this, Hidan needs to be connected to his body in order to control it. Kakuzu assists him in these instances 由 reattaching his limbs, allowing the wounds to heal with time. Hidan's inability to die is also used to Kakuzu's advantage, as he can attack Hidan all he wants without worrying about finding a new partner afterwards. Although the two dislike working together, this advantage makes them the ideal team.
During battle Hidan makes every attempt to acquire an opponent's blood where, upon consuming it, he draws a symbol on the ground that "links" him with his opponent. Once this link is created Hidan takes on a grim reaper-like appearance and becomes what is essentially a voodoo doll for his opponent; any damage that is done to Hidan is also done to them. Hidan first uses this ability to give himself nonfatal injuries that bring him pleasure due to the pain it causes to him and the opponent. Once he is done toying with opponents in this way he stabs himself in the heart, killing them. 链接 can be broken prematurely if Hidan is removed from the safety of his symbol, though it can easily be reestablished 由 simply reentering its borders. After Hidan uses this ability to kill Asuma Sarutobi, 鹿丸 Nara faces him in an attempt to gain revenge. Hidan is unable to form a link with 鹿丸 and eventually falls into one of Shikamaru's traps. With Hidan captured, 鹿丸 blows him up and buries the still-speaking remains under a pile of rubble. While his actual status is currently unknown, 晓组织 no longer considers him a member.
