Hidan (飛段) is the foul-mouthed partner of Kazuku and is the second newest member of Akatsuki 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 by stabbing himself in the chest and lying upon the ground. In addition to his religion Hidan has been gifted with immortality, and as such he is able to survive fatal wounds and even retains the ability to speak after being decapitated. Despite this, Hidan needs to be connected to his body in order to control it. Kakuzu assists him in these instances by 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.
